Hand type microphone device with touch sensor function
[0001]
The present invention relates to a hand type microphone device such as a wireless type or wire
type microphone, and more particularly to a hand type microphone device having a touch sensor
function.
[0002]
Conventionally, as a hand type microphone device, those having various structures are known.
Among them, for example, a hand type microphone used in a broadcasting station, a hall, etc. has
no power switch. Often.

In a hand-type microphone with a structure that does not have such a power switch (manually
turned on and off operation switches), in the case of a so-called wireless type, the power is turned
on and off substantially by turning the battery on and off. It corresponds by turning on and off.
Further, in the wired type, the power supply is substantially turned on and off by connecting or
extracting a microphone cable connected to the amplifier side.
[0004]
However, in such a wireless microphone, when the power is turned on and off by taking in and
out the battery, the power is kept on unless the battery is taken out even when not in use, so the
battery is wasted. There is a problem of consuming
Also, wired microphones may pick up unwanted sounds unless the microphone cable is removed.
[0005]
On the other hand, a hand type microphone with a power switch is supported by turning on and
off the switch. However, such a microphone with a power switch has a problem that the battery
or the power is consumed if the switch is turned off.
[0006]
Furthermore, as to both the wireless type and the wired type microphone devices, there is a
disadvantage that an impact sound when it is dropped unexpectedly may be input, which may
affect the acoustic device.
[0007]
Further, in the hand type microphone device having a structure without a power switch as
described above, the switch is turned on and off by detecting that a person stands or approaches
in front of the microphone. Also, conventionally, they have already been proposed (see, for
example, Patent Document 1 and Patent Document 2).

1 to 2 show an embodiment of a hand-type microphone device with a touch sensor function
according to the present invention, and in these drawings, in this embodiment, a wireless
microphone is exemplified as the hand-type microphone M. Will be described below.
However, the present invention is not limited to this, and may be a wired type connected by a
microphone cable.
[0024]
In the hand-type microphone M, the touch sensor 1 is formed on the entire surface of the grip
portion of the housing (microphone body 7) as apparent from FIG.
Then, the microphone M is configured to be powered on by touching any part of the grip portion
of the case.
That is, as shown in FIG. 1A, the touch sensor 1 detects this state and sends a signal to the
control unit 2 as the user's hand H touches and grips the case grip as shown in FIG. , The power
supply circuit 3 is to be turned on.
Further, as shown in (b) of the figure, when the hand H is released, the touch sensor 1 detects the
state and sends a signal to the control unit 2 to turn off the power supply circuit 3.
[0025]
Here, as the touch sensor 1, for example, a resistive type or a capacitive type is used.

In FIG. 2, reference numeral 4 is a microphone amplifier circuit, 5 is a modulation circuit, 6 is a
radio wave output circuit, 8 is a microphone head to which an audio signal is input, and 9 is an
antenna.
[0026]
In such a configuration, the radio wave output circuit 6 may be powered on by holding the grip
of the housing of the microphone M, and the radio wave output circuit 6 may be powered off
when released.
Alternatively, the power supply of the microphone amplifier circuit 4 may be turned on by
gripping the grip of the housing of the microphone M, and the power supply of the microphone
amplifier circuit 4 may be turned off by releasing it.
[0027]
The operation of the hand-type microphone M having such a configuration will be exemplified
below.
That is, in FIG. 2, when the touch sensor 1 mounted on the microphone body 7 is touched, a
signal is input from the touch sensor 1 to the control unit 2, and the control unit 2 controls the
power supply circuit 3 or the microphone amplifier circuit 4 of the microphone body 7. Power
control of the power supply or the radio wave output circuit 8 is performed.
When the hand H is released from the touch sensor 1, the signal operates to turn off the power
supply circuit 3, the microphone amplifier circuit 4, and the radio wave output circuit 8.
[0028]
With this configuration, the power is turned on simply by touching it and turned off by releasing
it, so it is possible to reduce the consumption of the battery and power as in the prior art, and
switch operation, inserting and removing the battery, or cable There is no need for troublesome
operations such as connection and removal, and usability is improved.

[0029]
Moreover, according to such a configuration, since the control circuit inside the housing can set
the power on / off control by the touch sensor 1, the difference in the housing due to the
presence or absence of the power switch can be eliminated. Commonality can be achieved.
Furthermore, since the power is turned off by leaving the user's hand H, even if the microphone
M is dropped accidentally, the power is cut off during the drop, so the impact sound at the time
of the drop affects the acoustic equipment. There are no problems.
[0030]
Here, in the embodiment described above, the case where the user turns on the power when
touching the hand H and turns off when releasing the hand H, for example, the power turns on
when the user touches the hand H once by touching it or the like Then, the circuit can be
configured such that the power is turned off when the user grips by touching the next.
[0031]
In addition, a predetermined time is delayed from when the touch sensor 1 provided on the grip
of the housing 7 of the microphone M is touched to the power on after the touch sensor 1 is
touched or from when it is released to when the power is turned off. A delay circuit may be
provided to adjust the power on / off timing.
[0032]
FIG. 3 shows an example in which the timer unit 12 for performing the delay operation as
described above is provided.
Here, in the figure, 10 is a terminal, and the terminal 10 is a communication cable from a
personal computer (PC) or the like (not shown), for example, a terminal for a connection cable
such as USB, and the cable is connected to this terminal 10 The mode switching unit shown by

place of the terminal 10 in FIG. 3 described above.
Here, the receiving unit includes the filter 21, the receiving circuit 22, and the demodulation
circuit 23, and is configured to perform mode switching control of the mode switching unit 11 by
wireless communication to the antenna 9 of the microphone M.
Of course, not limited to this, the mode setting of the mode switching unit 11 may be set in
advance by a dip switch or the like at the time of assembly.
In FIG. 4, reference numeral 13 denotes a filter.
[0034]
In the embodiment in FIG. 3 and FIG. 4 as described above, for example, the mode switched on at
the time of touch detection, the mode switched on after a predetermined delay time has elapsed
from touch detection, and the touch detection There is a mode etc. which are turned on by, and
turned off by the next touch detection. Even with such a configuration, substantially the same
effects as those of the embodiment described with reference to FIGS. 1 and 2 described above
can be obtained.

pseudo manner, for example, is stuck on the inside, thereby holding the touch on the microphone
stand. It is preferable that the sensor 1 be operated to turn on the power, and disconnecting the
microphone holder 20 turn off the power.
[0036]
Note that a capacitive tape may be used as the above-described tape 21. Then, this may be
detected by a capacitance sensor. Here, although the above description has described the case of
using the microphone holder 20 separately from the microphone stand, the present invention is
not limited to this, and the tape 21 may be directly attached to the inside of the microphone
stand.
[0037]
Furthermore, as a modification thereof, the microphone M described in the above-described
embodiment is held on a normal microphone stand, the touch sensor 1 is operated by touching
the hand, the power is turned on, and the touch is performed again. It may be configured to turn
off the power.
[0038]
The present invention is not limited to the structure described in the above embodiment, and it is
needless to say that the shape, structure, and the like of each part constituting the hand-type
microphone M can be appropriately modified and changed.
