Description

  The present invention relates to a hand type microphone device such as a wireless type or a wired type microphone, and more particularly to a hand type microphone device having a touch sensor function.

  Conventionally, there are known hand-type microphone devices having various structures. Among them, for example, hand-type microphones used in broadcasting stations, halls, etc., have no power switch. Often.

In a hand-type microphone having a structure that does not have such a power switch (an operation switch that is turned on and off by manual operation), in a so-called wireless type, the power is turned on and off by inserting and removing the battery. It is supported by turning it on and off.
Also, the wired type is supported by turning the power supply on and off substantially by connecting or disconnecting a microphone cable connected to the amplifier side.

However, in such a structure where the power is turned on and off by inserting and removing the battery, such as a wireless microphone, the battery remains wasted unless the battery is removed even when not in use. There is a problem of consumption.
Also, with a wired microphone, there is a possibility that unwanted sounds will be picked up unless the microphone cable is removed.

  On the other hand, a hand-type microphone with a power switch can be handled by turning the switch on and off. However, such a microphone with a power switch has a problem that a battery or a power source is consumed if the switch is forgotten to be turned off.

  Furthermore, as it applies to both wireless type and wired type microphone devices, there is a problem that an impact sound when it is dropped unexpectedly is input, which may affect the sound device.

  In addition, in the hand type microphone device having no power switch as described above, the switch is turned on / off by detecting that a person stands or approaches in front of the microphone. Has already been proposed (see, for example, Patent Document 1 and Patent Document 2).
