Abstract

【課題】マイクロホン感度が高くて摺動ノイズに強く、しかも外部騒音や振動を感知しにくく、高騒音下での通話用のマイクロホンとして、あるいは、音声認識入力用のマイクロホンとして好適な、小型で高感度の振動ピックアップ型マイクロホンを提供する。 【解決手段】第１のスペース５と第２のスペース６とを設けたハウジング１と、第１のスペース５に覆設される外部振動板２と、第２のスペース５の奥端部に空隙８を保持して収納されるマイクロホンユニット３とから成り、外部振動板２が覆設されることによって第１のスペース５に形成される気室７と第２のスペース６に形成される空隙８とが、細通路４を介して連通されることにより、外部振動板２によってピックアップされた音声振動が音波としてマイクロホンユニット３に伝達され、その伝達経路において、音波の周波数成分の内、音声周波数より高域の成分が減衰される。
