A through hole 14 is formed below the power generation member 13 of the rechargeable battery 10, that is, in a space portion. This through hole 14 collects ambient noise from the back and side surfaces, as in the back sound collecting hole 9 shown in FIG. A rubber packing 15 is inserted in the gap between the main body 5 of the mobile phone device and the rechargeable battery 10, and the through hole 14
Ambient noise input from the device is prevented from leaking through this gap. In this type of structure, the differential microphone 12 is inserted into the through hole 14, and the front sound collecting hole 8 that is a transmitter is provided on the front surface of the mobile phone device body 5. Since the through-hole 14 is located exactly opposite to the front sound collecting hole 8, the ambient noise input from the front sound collecting hole 8 and
Since it has an opposite phase to the ambient noise input from the back sound collector 16 via the through hole 14, the ambient noise can be suppressed as in the first embodiment.

め、雑音抑圧の効果をむしろ向上する。In the figure, the back sound collecting hole 9 and the back sound collecting portion 1 are shown.
The passage connecting 6 and 6 is not a straight line but a deformed passage. This passage is formed in a substantially L shape extending downward. In this embodiment, the power generation member 13 is applied to the case where the power generation member 13 exists at the position opposite to the front sound collecting hole 8. At this time, if the back circumferential sound collecting hole 9 is provided at a position exactly opposite to the front sound collecting hole 8, that is, inside the power generating member 13, the power generating member 13 is exposed from the inner wall surface of the back sound collecting hole 9, so that the back portion This is done in order to solve the problem that the sound collecting hole 9 cannot be provided at a position opposite to the front sound collecting hole 8. As an example of this application, in addition to the configuration shown in the figure, a back sound collecting hole 9 is formed in the space portion such as the left and right and the upper part of the rechargeable battery 10 avoiding the power generating member 13, A deformed passage that is not a straight line can be formed so as to connect with the sound part 16. In this configuration, the rear sound collecting holes 9 cannot be provided at positions directly opposite to the front sound collecting holes 8 and the ambient noise input from each of them does not have an antiphase relationship. Since the back sound collecting hole 9 can be provided at a position further away from the sound hole 8, the effect of noise suppression is rather improved.

They are different in that they are formed directly inside. In this embodiment, since there is no space in the rechargeable battery 10, the back sound collecting hole 9 is directly formed in the power generation member 13. In this type of configuration, the power generation member 13 is protected by covering the inner wall surface of the back sound collecting hole 9 formed in the power generation member 13 with the resin member 17 so that the power generation member 13 is not exposed. In this embodiment, it is possible to dispose a large power generation member 13 in which no space is present in the rechargeable battery 10, so that not only the battery capacity can be increased, but also the back sound collecting hole 9 The degree of freedom of arrangement can also be improved.
