<P>PROBLEM TO BE SOLVED: To provide a practically available and low-priced ear-cover type sound collector which is fixed only by mounting sound collecting covers which cover the ears onto a band and covering the ears, mounting to and removing from the ears can be facilitated, and collection sound pressure to the ears is increased by the ear covers without using any microphone, speaker, amplifier, battery and the like. <P>SOLUTION: (1) Ear covers 1a and 1b are fixed to a band 2, thereby facilitating mounting/removing. (2) Any speaker, microphone, amplifier and the like are abolished, thereby reducing manufacturing costs. (3) The ear covers are tightly mounted around the ears by a concatenation structure of the band and the ear covers. (4) A sound collector is structured to be hung from the neck, when it is not used, by removing the ear covers from the ears. <P>COPYRIGHT: (C)2012,JPO&INPIT |
