本発明はマイクロホン装置に口を近づけて送話
した際に発生する耳障りな音を防止するようにし
たマイクロホン装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a microphone device that prevents harsh sounds that occur when a user speaks by bringing his or her mouth close to the microphone device.
たとえば、インターホン装置の送受信器におい
て、送話口に口を近づけて送話した際、人の息に
よる風圧をマイクロホンが拾い、相手送受器にお
いて、非常に開き苦しいという問題があつた。 For example, in the transmitter/receiver of an intercom device, when a person speaks with his or her mouth close to the mouthpiece, the microphone picks up the wind pressure from the person's breath, making it extremely difficult for the other party's handset to open.

うにしてもよい。 1 is a case of a handset of an intercom device, for example, and this case has an annular wall 3 forming a first opening 2 on the back side and a second opening 4 spaced apart from the wall on the inside of this wall. A sound introduction hole 6 is formed between the projecting wall 5 and the wall 3 of the case, and a sound introducing cavity 7 is formed in the projecting wall 5 on the end side of the second opening 4. This space may be a hole drilled in the center of the projecting wall 7, or may be a notch as in this embodiment. Reference numeral 8 denotes a main body of a microphone such as a condenser microphone, and the peripheral edge of the front side end having the sound introduction hole 9 is connected to the first opening 2 of the wall 3.
At the same time, the end surface thereof is brought close to the end surface of the projecting wall 7, so that the entire surface of the second opening 4 is covered with the end surface of the microphone body 1. and,
A sound introduction hole 9 of the microphone main body 8 is made to face this opening 4. Note that 10 is a rubber cover for vibration isolation of the microphone body 8, and 11 is a lead wire. Moreover, the wall body 3 does not have to be formed by a projecting wall, but may be formed by leaving a portion where the end portion of the microphone main body 8 fits, and forming the other portion thick. Further, the second opening 4 may be formed by forming the projecting wall 7 in an annular shape.

た。 When making a call using an intercom device,
The speaker speaks into the microphone device of the handset. In this case, the sound enters the sound introduction hole 6, is guided from there to the sound introduction cavity 7 of the projecting wall 5, is then guided to the sound introduction hole 9 of the microphone body 8, and reaches the microphone body 8. In other words, since the sound reaches the sound introduction hole 9 of the microphone indirectly rather than directly, even when speaking with the mouth close to the microphone device, the wind pressure caused by the person's breath is weakened, and the sound is not heard as the sound generated from the receiver of the other party. will be of good quality. In the past, some people sometimes brought their mouths extremely close to the microphone, i.e., the transmitter, making it extremely difficult to hear the other party on the receiver. The situation has gradually eased, and it is no longer considered a problem.

も簡単であり、安価に製作できるものである。 As described in detail above, the present invention includes a wall forming a first opening on the back surface of the case, a projecting wall forming a second opening spaced apart from the wall on the inside of this wall, and A sound introduction hole is formed in the projecting wall between the wall body and the projecting wall, and the peripheral edge of the front side end of the microphone body is fitted into the first opening, and the front side end is fitted with the first opening. The end face of the microphone is brought close to the end face of the projecting wall, and the second opening faces the sound introduction hole of the microphone, so even when speaking with the mouth close to the microphone device, it is difficult to hear the voice on the other party's handset. The pain is greatly alleviated,
Further, since the wall body and the projecting wall are formed on the back surface of the case, and the sound introduction holes are formed therein, the structure is simple and can be manufactured at low cost.
