Abstract

PURPOSE:To easily mount the titled microphone without a special outfit by constituting it so that a vibration pick-up body may be fitted in a suspended condition in a space around a vibration sensing part. CONSTITUTION:An spindle body 301 is provided at the center part of a vibration sensing part 3, and a linking body 5 stuck and fixed at the center of a vibration pick-up body 4 is screwed and fixed at the tip of the spindle body 301. Thus, the pick-up body 4 is supported in the suspended condition in the internal space of a case 1. The bone-conduction microphone with such a constitution is fitted at the inner surface of a helmet, and when a diver puts on the helmet, the sensing part 3 contacts with the head at a suitable contact pressure. When the diver utters a voice, the vibration generated in the skull of the diver is sensed by the sensing part 3, transmitted through the spindle body 301 and the linking body 5 to the pick-up body 4, and outputted to a mike code 7.
