【考案の詳細な説明】
本考案は、頭部に装着して音声をピックアップする振動
型マイクロホンに関するものである。[Detailed Description of the Invention] The present invention relates to a vibrating microphone that is worn on the head and picks up sound.
頭部に装着され、外耳道における振動から音声をピック
アップする外耳道ピックアップ型マイクロホンがあるが
、このマイクロホンのｆ％性は第１図に示すように、高
域が低下しており、明瞭度が悪い欠点がある。There is an ear canal pickup type microphone that is worn on the head and picks up sound from vibrations in the ear canal, but as shown in Figure 1, the f% characteristic of this microphone is low in the high range and has poor clarity. There is.
又、振動型ピックアップで、前額部の音声を拾うと、第
２図に示すような特性となり、低域不足で、音質が悪く
なる。Furthermore, when a vibration-type pickup picks up sound from the forehead region, the characteristics shown in FIG. 2 occur, resulting in a lack of low frequencies and poor sound quality.
