circuit 103.
[0019]
Here, for example, when the headphone 108 is not connected to the HP jack 107, the switch 109
is switched to a state (OFF state) in which the output of the microphone amplifier 110 is not
supplied to the mixing circuit 103.

That is, the HP jack 107 determines connection and non-connection of the headphone 108, and
supplies a switch signal according to the determination result to the switch 105 and the switch
109, respectively.
The so-called relay control for controlling the switching operation of the switch 105 and the
switch 109 is performed by this switching signal. Therefore, when the headphone 108 is not
connected to the HP jack 107, the switch 109 is turned off and the switch 105 is switched to the
speaker 106, and the headphone 108 is connected to the HP jack 107. When the switch 109 is

At this time, since the switch 109 is in the ON state by the switching operation as described
above, the external sound signal amplified by the microphone amplifier 110 is supplied to the
mixing circuit 103 via the switch 109.
[0028]
Therefore, the mixing circuit 103 is supplied with the tone signal obtained by the tone
generation circuit 102 and the D / A converter as described above, and the external sound signal

as described above, the mixed signal amplified by the power amplifier 104 is transmitted to the
HP jack 107 via the switch 105. Supplied.
[0032]
Therefore, the mixed signal amplified by the power amplifier 104 is supplied from the switch
105 to the HP jack 107, and the headphone 108 connected to the HP jack 107 has a sound
based on the mixed signal, that is, a musical tone and an external sound. It is output.

For example, even when the electronic piano 100 is played using the headphones 108, the
convenience can be increased because the user can hear the sound of the telephone and the
speaking voice during the performance.
In addition, since it is possible to input a key depression or key release on the keyboard unit 101
and an operation sound for stepping on a pedal (not shown) as an external sound with the
speaker 106, it is as if playing a live instrument, and As such, it is possible to obtain a state in
which the headphones 108 are not in use and to increase the sense of reality.
Furthermore, by having the speaker 106 function as a microphone, external sound can be easily
input without complicating the circuit configuration.
That is, the above effects can be obtained at low cost.
[0034]

operates the operation information such as the key number of the key operated by the keyboard
unit 201 and the tone parameter information set by the operation of the operation panel unit
215 or the like. Information is provided.
[0043]
The tone generation circuit 202 includes a plurality of tone generation channels (not shown) and
is configured to be capable of generating a plurality of tones.
Then, the tone generation circuit 202 forms tone data in digital data format based on operation
information of the keyboard unit 201 and the operation panel unit 215.
[0044]
The musical tone data obtained by the musical tone generation circuit 102 is converted into an
analog signal by a D / A converter (not shown) and supplied to the mixing circuit 103 and to the
power amplifier 204.
[0045]
The power amplifier 204 amplifies musical tone data (musical tone signal) analogized by the D /
A converter so as to obtain power for driving the speaker 206.
08-05-2019
12
Then, the power amplifier 204 supplies the amplified tone signal to the switch 205.
[0046]
Here, for example, when the headphone 208 is not connected to the HP jack 207, the switch 205
is switched to a state (the ON state) in which the output of the power amplifier 204 is supplied to
the speaker 206.
[0047]

obtained at low cost.
[0057]
Next, a third embodiment will be described.
[0058]
An electronic musical instrument according to the present invention is applied to, for example, an
electronic piano 300 as shown in FIG.

08-05-2019
15
As shown in FIG. 3, the electronic piano 300 has a configuration in which the correction circuit
150 is provided to the electronic piano 100 of FIG. 1 as described above.
That is, in the electronic piano 300, the correction circuit 150 is provided between the
microphone amplifier 110 and the switch 109, and the output of the operation panel unit 115 is
supplied to the correction circuit 150.
[0060]
In the electronic piano 300 of FIG. 3, the same parts as those of the electronic piano 100 of FIG.
1 operate by the same reference numerals, and the detailed description thereof will be omitted.
[0061]
First, by the control of the control circuit as described above, operation information such as tone
parameters set by the operation of the operation panel unit 115 is supplied to the tone
generation circuit 202 and also to the correction circuit 150.
[0062]
The correction circuit 150 includes an equalizer, a reverberation circuit, and the like, and when
the headphone 108 is connected to the HP jack 107, a predetermined external sound signal is
output from the microphone amplifier 110 based on the operation information of the operation
panel unit 115. Perform correction processing.
[0063]
Specifically, the correction circuit 150 corrects the tone of the external sound signal from the
microphone amplifier 110 to the tone selected by the operation panel 115 based on the
operation information of the operation panel unit 115, for example. Do.
When the correction circuit 150 selects an effect such as reverberation or equalization on the
operation panel 115 based on the operation information of the operation panel unit 115, for
example, the selected effect is output from the microphone amplifier 110. A correction process to
be added to the sound signal is performed.
08-05-2019
16
[0064]
At this time, the tone generation circuit 102 forms tone data based on the operation information
of the operation panel unit 115 as described above.
More specifically, the tone generation circuit 102 operates the operation information of the
operation panel unit 115, such as tone data having the tone color selected on the operation panel
115 and tone data to which effects such as reverberation and equalization selected on the
operation panel 115 are added. Based on the tone data is formed.
[0065]
Therefore, the external sound signal subjected to the correction processing by the correction
circuit 150 is output in a state in which the tone data, the effect, and the like are matched with
the tone data output from the tone generation circuit 102.
Thus, when the headphone 108 is connected to the HP jack 107, the musical tone and the
external sound are output from the headphone 108 in the same state in accordance with the
operation of the operation panel unit 115, so that the sense of reality can be further enhanced.
[0066]
In the electronic piano 300 described above, an automatic gain control (AGC: Automatic Gain
Control) process may be performed on the external sound signal from the microphone amplifier
110 by the correction circuit 150.
Further, a correction process for emphasizing the frequency characteristic may be performed on
the external sound signal from the microphone amplifier 110, or the frequency characteristic of
the speaker 106 may be corrected.
Furthermore, a stereo effect may be added to the external sound signal from the microphone

17
amplifier 110.
Furthermore, stereo processing may be performed not only on the microphone amplifier 110 but
also on the entire apparatus such as the tone generation circuit 102 and the speaker 106. For
example, the above-mentioned stereo processing may be performed by changing the right and
left phases by a phase correction circuit or by delaying a signal by a delay element such as a BBC
(Bucked Brigade Device) to give left and right time differences.
[0067]
Further, even in the electronic piano 400 in which the correction circuit 250 is provided to the
electronic piano 200 of FIG. 2 as shown in FIG. 4, the same effect as the electronic piano 300 of
FIG. 3 can be obtained. In the case of the electronic piano 400, as shown in FIG. 4, the correction
circuit 250 is provided between the microphone amplifier 210 and the mixing circuit 203, and
the output of the operation panel unit 115 is supplied to the correction circuit 250.

In the first to third embodiments described above, the speaker is configured to function as a
microphone when headphones are used, but a microphone is directly provided to the
headphones, and an external sound is input by this microphone. May be As a result, external
sounds in the vicinity of the performer's ear are input, and the presence can be more naturally
enhanced.
[0069]
Further, it goes without saying that the electronic musical instrument according to the present
invention can be applied not only to electronic pianos, but also to electronic musical instruments
to which headphones can be connected, for example, a guitar synthesizer and a drum pad. In
particular, in an electronic musical instrument that generates a musical tone by an operation
such as hitting a keyboard, a pedal, a string or a drum, the above-described effect is remarkable
by inputting the operation sound as an external sound.

As described above, according to the present invention, when headphones are connected to the
output means, the musical tone output from the speaker is cut off and the speaker is used as a
microphone as an external sound input means, and By outputting the external sound obtained by
the speaker and the musical tone based on the operation, not only the musical tone based on the
operation but also the external sound can be heard, so the headphone can be used. It can
eliminate the feeling of pressure and the unnaturalness of the sound. In addition, for example,
since the user can also hear the sound of a telephone and the speaking voice while playing an
instrument, the convenience can be improved. Further, by causing the speaker to function as a
microphone to input an external sound, the external sound can be easily input, and the cost of
the apparatus can be reduced. Further, by including the operation sound of the musical
instrument as the external sound to be input, it is possible to obtain a feeling as if playing a live
instrument and as if not using headphones. It can be obtained and can increase the sense of
reality. For example, by inputting the sound of striking the keyboard of the electronic piano as
the external sound, it is possible to hear the tone of striking the keyboard of the electronic piano
and the musical tones to be produced by the operation, and play the electronic piano without
using headphones. You can get the condition you are doing. Furthermore, since the tone color of
the external sound output from the headphone is corrected based on the musical tone generated
based on the operation, the external sound obtained by the speaker from the headphone, and The
tone based on the operation can be output with the same tone color. For example, when
equalizing or reverberation is applied to a musical tone based on operation, the external sound
obtained by the speaker can be corrected by equalizing or reverberating, so that the sense of
reality can be further enhanced naturally. . Further, according to the present invention, when the
headphone is connected to the output means, the external sound signal obtained by the speaker
is always supplied to the mixing means. Since there is no need to provide means for switching the
input, the cost of the apparatus can be further reduced. Further, according to the present
invention, by providing the microphone in the headphone and inputting the external sound by
the microphone, the external sound in the vicinity of the performer's ear will be input, and the
sense of reality will be more naturally It can be increased.
