[0017]
On the other hand, the button group 20 provided in the right operation area 22 is provided so as
to surround the BUILD UP group 25 provided so as to surround the top of the operation knob 21
in plan view and the bottom of the operation knob 21 in plan view. BREAK DOWN group 26 is

[0018]
Buttons of various audio effects are pressed, and a lamp 60 located inside the selected and
pressed effect button lights up.
[0019]
The operator selects an audio effect to be added to the input music by pressing each button in
the button group 20.
When a plurality of audio effects are selected, the effects to be added to the music are switched
in the selection order, that is, in the order of pressing the button. When the DJ effector 1 is

generation unit 14, an audio signal processing unit 15, and a signal output unit 16.
[0021]

The signal input unit 11 inputs an audio signal of music from an external device such as the DJ
player 46 or the like. The operation unit 12 includes an operation knob 21 which can be rotated
and pushed in, as will be described in detail later. The operation unit 12 detects the rotation
angle of the operation knob 21 by the variable resistor 51, detects the amount of depression of
the operation knob 21 by the pressure sensor 52, and outputs the detection result to the
parameter generation unit 14. The variable resistor 51 is an example of the “rotation
acquisition unit” and the “rotation detection unit” in the claims. The pressure sensor 52 is an
example of the “push acquisition unit” and the “push detection unit” in the claims.
[0022]
The parameter generation unit 14 generates a switching cycle parameter based on the rotation
angle of the operation knob 21, and generates a sound generation frequency parameter based on
the amount of depression of the operation knob 21. The switching cycle parameter is for
changing the switching cycle for sequentially switching the audio effect added to the music input
to the signal input unit 11 from a plurality of types of audio effects. The sounding number
parameter is for changing the sounding number of the audio effect in the switching period. The
parameter generation unit 14 generates a switching cycle parameter and a sound generation
frequency parameter at timing matched with the beginning of the beat of the music to which the
audio effect is added, and outputs the parameter to the audio signal processing unit 15. The DJ
effector 1 may be provided with a beat position detection unit (not shown) for detecting the beat
position of the music, and the beat position of the music is detected in an external device such as
the DJ player 46 and the DJ effector 1 beats Position data may be acquired.
[0023]
The audio signal processing unit 15 adds an audio effect to the input audio signal based on the
switching period parameter and the number of times of sound generation parameter from the
parameter generating unit 14. Further, the signal output unit 16 outputs the audio signal
processed by the audio signal processing unit 15 to the DJ mixer 45. Thereby, the sound in
which the audio effect is added to the music is output from the speaker 47.
[0024]
11-04-2019

Next, with reference to FIG. 3, the change of the switching period of the additional sound based
on the rotation angle of the operation knob 21 will be described. Around the operation knob 21,
a quarter note mark 30a, an eighth note mark 30b, a sixteenth note mark 30c, and a thirtysecond note mark 30d are displayed. When the operation knob 21 is turned to the rotation angle
of the quarter note mark 30a, the rotation angle of the eighth note mark 30b, the rotation angle
of the sixteenth note mark 30c, the rotation angle of the thirty second note mark 30d, the
detection result of the rotation angle The parameter generation unit 14 generates the first
switching cycle parameter, the second switching cycle parameter, the third switching cycle
parameter, and the fourth switching cycle parameter, respectively. When the audio signal
processing unit 15 receives the first switching cycle parameter, the switching cycle for switching
the audio effect to be added from the plurality of audio effects is set to one beat. When the
second switching cycle parameter is received, the audio signal processing unit 15 receives the
switching cycle as 1⁄2 beat and when the third switching cycle parameter is received, the
switching cycle as 1⁄4 beat and the fourth switching cycle parameter Then, the switching cycle is
set to 1/8 beat. For example, it is assumed here that “TRANS 41”, “CLAP 42”, “HIHAT 43”
and “ROLL 44” are selected as audio effects. When the operator such as the DJ player 46
rotates the operation knob 21 to the rotation angle of the quarter note mark 30a, the parameter
generation unit 14 generates the first switching cycle parameter, and the audio signal processing
unit 15 performs the switching cycle. Make one beat. As a result, the audio effect added to the
music is switched in the order of “TRANS 41”, “CLAP 42”, “HIHAT 43” and “ROLL 44”
for each beat (see FIG. 3A). When the operator rotates the operation knob 21 to the rotation
angle of the eighth note mark 30b, the parameter generation unit 14 generates the second
switching cycle parameter, and the audio signal processing unit 15 halves the switching cycle.
Make a beat. As a result, the audio effect is switched in the order of “TRANS 41”, “CLAP 42”,
“HIHAT 43” and “ROLL 44” every half beat (see FIG. 3B). The same applies to the case
where the operation knob 21 is rotated to the rotation angle of the sixteenth note mark 30c and
the rotation angle of the thirty-second note mark 30d.
[0025]
The change of the switching cycle of the audio effect based on the rotation angle of the operation
knob 21 has been described above, but the number of selection of the switching cycle by the
rotation operation is not four as in this embodiment, but three or less. There may be more than
one. Further, in the present embodiment, the option of the switching cycle is fixed to one beat,
1/2 beat, 1/4 beat, and 1/8 beat, but this is because the operator selects a plurality of switching
cycles. It may be configured to be selectable.
11-04-2019

[0026]
Next, with reference to FIG. 4, a change in the number of times of sound production of the audio
effect based on the amount of depression of the operation knob 21 will be described. The details
of the operation knob 21 will be described later, but the pushable amount is 3 mm. The position
of the operation knob 21 is "small" (for example, 0 mm or more and less than 1 mm), the position
for "medium" (for example, 1 mm or more and less than 2 mm), and "large" When the pressing
operation is performed to the position of, the parameter generating unit 14 generates the first
sound generation frequency parameter, the second sound generation frequency parameter, and
the third sound generation frequency parameter based on the detection result of the pressing
amount. When the audio signal processing unit 15 receives the first sounding frequency
parameter, the sound signal processing unit 15 sets the sounding frequency of the audio effect in
the switching cycle to one. The audio signal processing unit 15, when receiving the second
sounding number parameter, sets the sounding number to two, and when receiving the third
sounding number parameter, sets the sounding number to four.
[0027]
For example, here, it is assumed that “TRANS 41”, “CLAP 42”, “HIHAT 43” and “ROLL
44” are selected as the audio effect as described above. The operation knob 21 is rotated to the
rotation angle of the quarter note mark 30a, and the switching cycle is one beat. When the
operator operates the operation knob 21 to the position of the pressing amount "small", the
parameter generating unit 14 generates the first sound generation number parameter, and as a
result, the audio effect added to the music has a switching cycle It is pronounced once in (one
beat) (see FIG. 4 (a)). In addition, when the operator operates the operation knob 21 to the
position of the pressing amount “middle”, the parameter generating unit 14 generates the
second sound generation number parameter, and as a result, the audio effect has a switching
cycle (one beat Sounded twice in the)) (see FIG. 4 (b)). In addition, when the operator operates
the operation knob 21 to the position of the pressing amount "large", the parameter generating
unit 14 generates the third sound generation number parameter, and as a result, the audio effect
has a switching cycle (one beat Sounds four times in) (see FIG. 4 (c)).
[0028]
In this way, the number of times of sound generation of the audio effect added to the music is
changed once per beat, twice per beat, four times per beat based on the amount of depression of
the operation knob 21. be able to.
11-04-2019

[0029]
Although the change in the number of times of sound generation of the audio effect based on the
amount of depression of the operation knob 21 has been described above, the number of
selections of the number of times of sound generation by the depression operation is not three
but four or less. There may be more than one.
In the present embodiment, the choice of the number of times of sound generation is fixed to
once, twice, or four times, but this may be configured so that the operator can select from among
a plurality of kinds of number of times of sound generation.
[0030]
Next, with reference to FIG. 5, the case where the operation of switching the switching cycle and
the operation of switching the number of times of sound generation are simultaneously
performed, that is, the case where the rotation operation and the pressing operation of the
operation knob 21 are simultaneously performed will be described. As described above, the
parameter generation unit 14 generates the switching cycle parameter and the number of times
of sound generation parameter at the timing matched with the beginning of the beat of the
music, and outputs the parameter to the audio signal processing unit 15. Therefore, even when
the rotation operation and the pressing operation of the operation knob 21 are performed in the
middle of the beat, the switching cycle and the number of times of sound generation change from
the beginning of the next beat.
[0031]
First, in the first beat, the rotation angle of the operation knob 21 is rotated to the range of the
quarter note mark 30a, and the pushing amount is "small". At this time, the switching cycle is one
beat and the number of times of sound generation is one. Therefore, "TRANS 41" is sounded once
at the first beat.
[0032]
11-04-2019
10
During the first beat, the operator sets the rotation angle of the operation knob 21 within the
range of the eighth note mark 30 b and sets the pressing amount to “middle”. As a result, in
the second beat, the switching cycle changes to 1⁄2 beat and the number of times of sound
generation changes to 2 times. For this reason, "CLAP42" is pronounced at the beginning of the
second beat, and "HIHAT" is pronounced one half beat after that. Also, "CLAP 42" sounds twice in
1/2 beat. Similarly, "HIHAT 43" is pronounced twice in 1/2 beat.
[0033]
During the second beat, the operator sets the rotation angle of the operation knob 21 within the
range of the sixteenth note mark 30 c and returns the amount of depression to “small”. Thus,
in the third beat, the switching cycle changes to 1/4 beat and the number of times of sound
generation changes to one. Therefore, "ROLL 44" is pronounced at the beginning of the third
beat, "TRANS 41" is pronounced after one-fourth beat, "CLAP 42" is pronounced after one-fourth
beat, and one-fourth later "HIHAT 43" is pronounced. Also, "ROLL 44" sounds once in 1/4 beat.
Similarly, "TRANS 41", "CLAP 42" and "HIHAT 43" each sound once in 1/4 beat.
[0034]
During the third beat, the operator returns the rotation angle of the operation knob 21 to within
the range of the quarter note mark 30 a and makes the pressing amount “large”. Thus, at the
fourth beat, the switching cycle changes to one beat, and the number of times of sound
generation changes to four. Therefore, "ROLL 44" is sounded four times at the fourth beat.
[0035]
As described above, according to the DJ effector 1 of the present embodiment, by rotating the
operation knob 21, the parameter generation unit 14 changes the switching cycle parameter, and
the audio signal processing unit 15 changes the switching cycle. Further, by pressing the
operation knob 21, the parameter generation unit 14 changes the sound generation frequency
parameter, and the audio signal processing unit 15 changes the sound generation frequency.
Therefore, the operation to change the switching cycle and the operation to change the number
of times of sound generation can be performed by one operation element. In particular, in DJ
play where quick and accurate operation is required, remarkable effects can be obtained. In
11-04-2019
11
addition, the parameter generation unit 14 generates the switching period parameter and the
number-of-pronunciation number parameter at the timing matched to the beginning of the beat
of the music to which the audio effect is added, so that the rotation operation and the pressing
operation of the operation knob 21 Even in the middle of the switching cycle and the number of
times of pronunciation change from the beginning of the next beat. Therefore, the operator can
add the audio effect according to the beat timing of the music without performing the rotation
operation and the pressing operation according to the beat timing of the music. Further, the
parameter generation unit 14 may generate the switching cycle parameter and the number of
times of sound generation parameter at timing based on the beat position of the music, not
limited to the timing matched to the beginning of the beat of the music. For example, the
switching period parameter and the number-of-pronunciations parameter may be generated at
timing matched to the 1/2 beat of the music.
[0036]
A modification of the present embodiment will be described with reference to FIG. The DJ
effector 1 according to the modification has substantially the same configuration as the abovedescribed DJ effector 1 except that the control unit 17 is further provided.
[0037]
Here, the parameter generation unit 14 generates the switching period parameter and the
number-of-sounds parameter regardless of the timing of the beat of the music.
[0038]
The control unit 17 outputs the switching cycle parameter and the number-of-pronunciation
number parameter generated by the parameter generation unit 14 to the audio signal processing
unit 15 at a timing aligned with the beginning of the beat of the music to which the audio effect
is added.
[0039]
As described above, the parameter generation unit 14 may generate the switching cycle
parameter and the sound generation frequency parameter, and the control unit 17 may control
the output of the switching cycle parameter and the sound generation frequency parameter.
11-04-2019
12
Also in this case, even when the rotation operation and pushing operation of the operation knob
21 are performed in the middle of a beat, the switching cycle and the number of times of sound
generation change from the beginning of the next beat.
Therefore, the operator can add the audio effect according to the beat timing of the music
without performing the rotation operation and the pressing operation according to the beat
timing of the music. Further, the parameter generation unit 14 may generate the switching cycle
parameter and the number of times of sound generation parameter at timing based on the beat
position of the music, not limited to the timing matched to the beginning of the beat of the music.
[0040]
The operation unit 12 will be described with reference to FIGS. 7 and 8. In the following
description, the upper and lower sides on the sheet of FIG. 7 will be described as “upper and
lower”. Of course, this direction is for convenience of explanation, and it is not limited to this
direction with regard to the implementation of the present invention.
[0041]
As shown in FIG. 7, the operation unit 12 is a rotary variable resistor 51 (hereinafter, also simply
referred to as “variable resistor 51”) provided with the operation knob 21 projecting from the
upper surface of the upper case 61. ), The mounting plate 62 to which the variable resistor 51 is
attached, the damper 63 provided on the peripheral edge of the mounting plate 62, and the
position restricting convex projecting from the lower case 64 toward the peripheral edge of the
mounting plate 62 A portion 65, a supporting plate 66 provided below the mounting plate 62, a
compression coil spring 67 provided between the mounting plate 62 and the supporting plate
66, and fixed to the lower case 64 below the supporting plate 66 And a pressure sensor 52.
[0042]
The variable resistor 51 includes, in order from the bottom, a volume substrate 68 on which a
resistance pattern (not shown) is formed, a stepped cylindrical case portion 71 inserted through
11-04-2019
13
an opening 69 formed on a mounting plate 62, and a resistance pattern. A rotary shaft 72 for
rotating a sliding element (not shown) sliding on and a cylindrical operation knob 21 with a lid,
which is fixed to the tip of the rotary shaft 72, is provided. The variable resistor 51 is fixed to the
mounting plate 62 by screwing the volume substrate 68 to the lower surface of the mounting
plate 62.
[0043]
When the operator rotates the operation knob 21, the rotary shaft 72 and the slider rotate, and
the resistance value of the variable resistor 51 changes. Thereby, the output voltage or the
output current is changed, and the rotation angle of the operation knob 21 is detected. The
parameter generating unit 14 generates the four types of switching cycle parameters described
above according to the detected rotation angle. The click position may be provided at one or
more locations in the rotational direction of the operation knob 21. A touch sensor 73 is attached
to the upper surface and the outer peripheral surface of the operation knob 21 so that it can be
detected whether the operator is touching the operation knob 21 or not.
[0044]
Variable resistor 51 is supported on support plate 66 via mounting plate 62 and compression
coil spring 67. For this reason, the operation knob 21 of the variable resistor 51 can be pushed
in against the compression coil spring 67.
[0045]
The mounting plate 62 is formed in a substantially disc shape, and an opening 69 through which
the case 71 of the variable resistor 51 is inserted is formed at the center.
[0046]
At the peripheral edge portion of the mounting plate 62, guide holes 75 through which guide
pins (not shown) extending downward from the upper case 61 are formed at three locations.
The three guide holes 75 are provided at equal angular intervals, ie, 120 ° intervals, around the
11-04-2019
14
center of the mounting plate 62. The mounting plate 62 is vertically slidable while being guided
by the guide pins. For this reason, when the operation knob 21 is pushed downward, the
mounting plate 62 slides downward against the compression coil spring 67. When the pressing
force of the operation knob 21 is reduced in a state where the mounting plate 62 slides
downward, the mounting plate 62 is biased by the compression coil spring 67 and slides upward.
The guide hole 75 has a diameter with a margin for the guide pin. Thereby, when the operator
pushes the operation knob 21 obliquely to the vertical direction, the mounting plate 62 is
inclined obliquely, that is, inclined to a plane perpendicular to the extending direction of the
guide pin. In this state, the mounting plate 62 can slide vertically.
[0047]
In addition, boss-shaped upper spring positioning portions 76 are provided in a protruding
manner at three locations at the peripheral edge of the lower surface of the mounting plate 62.
Similar to the guide holes 75 described above, the three upper spring positioning portions 76 are
provided at equal angular intervals around the center of the mounting plate 62. The upper spring
positioning portion 76 positions the upper end portion of the compression coil spring 67.
[0048]
Furthermore, dampers 63 are provided at three locations at the peripheral edge portion of the
mounting plate 62. The three dampers 63 are provided at equal angular intervals around the
center of the mounting plate 62 in the same manner as the above-described guide holes 75 and
the like.
[0049]
The damper 63 includes a short cylindrical cylinder portion 77 attached to the peripheral portion
of the mounting plate 62, and a rod portion 78 which penetrates the cylinder portion 77 and
whose upper end is fixed to the lower surface of the upper case 61. . The damper 63 buffers the
downward slide of the mounting plate 62. The pressing force necessary for the pressing
operation of the operation knob 21 is adjusted by the damper 63. That is, the damper 63 allows
the operation knob 21 to be pushed in with an appropriate pushing force.
11-04-2019
15
[0050]
The position restricting convex portions 65 are protruded from the lower case 64 toward the
peripheral edge portion of the mounting plate 62 at three locations. The three position regulation
convex parts 65 are provided at equal angular intervals around the center of the mounting plate
62 as in the case of the above-mentioned guide holes 75 and the like. The position restriction
convex portion 65 restricts the downward sliding end position of the mounting plate 62, that is,
the pushing end position of the operation knob 21 by the mounting plate 62 sliding downward
(see FIG. 7B). doing. Thereby, the slidable amount of the mounting plate 62 in the vertical
direction, that is, the pushable amount of the operation knob 21 is, for example, 3 mm.
[0051]
The support plate 66 is configured in a substantially rounded square regular triangle plate shape,
and a lower spring positioning portion (not shown) is formed on the upper surface of each
corner. Further, at the central portion of the lower surface of the support plate 66, a pressing
portion 81 shaped like a circular arc surface is provided in a protruding manner. The pressing
portion 81 is a portion for pressing a pressure receiving portion 82 (described later) of the
pressure sensor 52 when the operation knob 21 is pressed. By forming the pressing portion 81
in an arc shape, the pressure receiving portion 82 can be appropriately pressed even when the
mounting plate 62 is inclined.
[0052]
The compression coil spring 67 is provided between the mounting plate 62 and the support plate
66 at three locations where the upper spring positioning portion 76 and the lower spring
positioning portion are formed. That is, the three compression coil springs 67 are provided at
equal angular intervals around the operation knob 21 when viewed from the direction
perpendicular to the mounting plate 62. The compression coil spring 67 biases the mounting
plate 62 in the direction opposite to the pushing direction of the operation knob 21, that is,
upward. In place of the compression coil spring 67, another elastic body such as a leaf spring or
a rubber-like member may be used.

The pressure sensor 52 includes a sensor substrate 83 and a pressure receiving portion 82
provided on the sensor substrate 83. The pressing portion 81 of the support plate 66 is in
contact with the pressure receiving portion 82. When the operator presses the operation knob
21, the pressure receiving portion 82 is pressed via the mounting plate 62, the compression coil
spring 67 and the support plate 66. The pressure sensor 52 detects the pressing force applied to
the pressure receiving portion 82.
[0054]
In the operation unit 12 configured as described above, when the operator presses the operation
knob 21 against the compression coil spring 67, the mounting plate 62 slides downward
according to the amount of depression, and the compression coil spring 67 To contract. Further,
due to the nature of the compression coil spring 67, that is, the hook's law, the larger the
pressing amount of the operation knob 21, that is, the larger the contraction amount of the
compression coil spring 67, the larger the pressing force on the operation knob 21 becomes. The
pressing force on the operation knob 21 is applied to the pressure receiving portion 82 via the
mounting plate 62, the compression coil spring 67 and the support plate 66, and is detected by
the pressure sensor 52. In other words, the operation unit 12 converts the pressing amount of
the operation knob 21 into a pressing force by the compression coil spring 67 interposed
between the operation knob 21 and the pressure receiving unit 82, and detects the pressing
force by the pressure sensor 52. Thus, the amount of depression of the operation knob 21 is
detected.
[0055]
The above-mentioned parameter generation unit 14 generates three kinds of sound generation
frequency parameters in accordance with the pressure detected by the pressure sensor 52, that
is, the amount of depression of the operation knob 21. For example, when the amount of
depression is "small", that is, less than 1 mm (detection pressure is less than 2 N), the parameter
generation unit 14 generates the first sounding frequency parameter, and the amount of
depression is "medium", that is, 1 mm or more and less than 2 mm (detection When the pressure
is 2N or more and less than 4N, the second sound generation frequency parameter is generated,
and when the pressing amount is "large", that is, 2 mm or more (the detection pressure is 4N or
more), the third sound generation frequency parameter is generated. The click position may be
provided at one or a plurality of places in the pressing direction of the operation knob 21.

As described above, according to the operation unit 12 of the present embodiment, when the
operation knob 21 can be depressed, the operator adjusts the operation amount, that is, the
pressing force in the operation of pressing only without pushing. The amount of operation, that
is, the amount of pressing can be easily adjusted. Thereby, the operator can operate so as to
achieve the target operation amount. That is, when the operator presses the operation knob 21, it
is possible to generate the target sound generation frequency parameter. Furthermore, as
described above, the operation unit 12 converts the pressing amount of the operation knob 21
into a pressing force by the compression coil spring 67 interposed between the operation knob
21 and the pressure receiving portion 82, and the pressing force is By detecting, the pressing
amount of the operation knob 21 is detected. Thus, even if the amount of indentation is a minute
amount (for example, in the unit of millimeter), the amount of indentation can be detected.
[0057]
Furthermore, the operation end 12 includes the position restricting convex portion 65, whereby
the push-in end position of the operation knob 21 is restricted. As a result, the compression coil
spring 67 does not contract excessively, and it is possible to prevent the pressure receiving
portion 82 of the pressure sensor 52 from being applied with a pressing force equal to or higher
than the rated pressure.
[0058]
Further, in the operation unit 12, three compression coil springs 67 are provided in a dispersed
manner around the operation knob 21 when viewed from the direction perpendicular to the
mounting plate 62. As a result, when the operator pushes the operation knob 21 obliquely to the
vertical direction, the pressing amount of the operation knob 21 can be appropriately set even
when the mounting plate 62 slides downward in the obliquely inclined state. It can be detected.
In other words, the operator does not have to press the operation knob 21 downward exactly,
and the operability is improved. Furthermore, when the three compression coil springs 67 are
provided at equal angular intervals around the operation knob 21 when viewed from the
direction perpendicular to the mounting plate 62, the mounting plate 62 is inclined in any
direction. Also, the amount of depression of the operation knob 21 can be detected appropriately.
As a matter of course, the number of compression coil springs 67 is not limited to three. The

same applies to the guide hole 75, the guide pin, the damper 63 and the like.
[0059]
Furthermore, in the operation unit 12, the rotational axis 72 direction and the pushing direction
of the operation knob 21 coincide with each other, but the relationship between the two
directions is not limited at all. For example, the configuration in which the rotational axis 72
direction is orthogonal It may be. However, as in the present embodiment, when the direction of
the rotation shaft 72 of the operation knob 21 coincides with the pushing direction, the operator
rotates the operation knob 21 by one operation such as screwing in the operation knob 21. Both
operation and pushing operations can be performed. Therefore, the operator can change the
switching period and the number of sounds by one operation.
[0060]
In the above embodiment, the operation knob 21 of the variable resistor 51 is exemplified as the
operation element for generating the switching cycle parameter and the sound generation
frequency parameter, but if the rotation operation and the pushing operation are possible, The
form does not matter. For example, jog dials, which are often mounted on the DJ player 46, may
be used. Also, these operators may be mounted on the remote controller. The controller may be
mounted on a DJ controller used in connection with a PC.
[0061]
Further, in the above embodiment, the parameter generation unit 14 generates the switching
cycle parameter based on the detected rotation angle, and generates the sound generation
frequency parameter based on the detected depression amount. It may be That is, the parameter
generation unit 14 may generate the sound generation frequency parameter based on the
detected rotation angle, and generate the switching cycle parameter based on the detected
depression amount.
[0062]
Further, the parameters obtained by the manipulation knob 21 may not necessarily be one
parameter, and a complex of a plurality of parameters may be used as a switching cycle

parameter or a number-of-pronunciation parameter.
[0063]
In the above embodiment, although the case where the additional sound control device of the
present invention is applied to the DJ effector 1 has been exemplified, even if applied to DJ
equipment other than the DJ effector 1 (DJ mixer 45, DJ player 46, etc.) good.
Further, the additional sound control device of the present invention may be applied to audio
devices other than DJ devices. Examples of the audio device include a CD player and an electronic
musical instrument.
[0064]
In the present embodiment, the “additional sound control device” in the claims is exemplified
as a device having the operation unit 12 and the parameter generation unit 14 as main
components. However, the “additional sound control device” does not have to include the
operation unit 12 and may be configured to acquire the rotation angle and the pressing amount
of the operation element provided in the external device. Further, in the present embodiment,
“audio equipment” in the claims is exemplified as a device having the operation unit 12 and
the audio signal processing unit 15 as main components. In the present embodiment, the audio
signal processing unit 15 changes the switching cycle and the number of times of sound
generation based on the switching cycle parameter and the number of times of sound generation
parameter, but is not limited thereto.
