Summary form only given, as follows. A vibration pick-up type ear microphone was developed in order to make howlingless,mask and free hand microphones or the like. Instead of monodirectional, noise cancelling, laryngeal and forehead microphone, this microphone is made by use of a pie3o element which is put in the ear along the canal and picks up the bone conducted sound by the principle of acceleration type vibration pick??up. By use of this newly developed microphone, phonating aid for patients with highly disturbed voices, loudspeaker built in gas masks, microphones used in airports, microphones for patrolling cars and wireless communicating apparatuses employed in industry or constructive fields have been designed and plays a very important role in daily use.
