Electro-acoustic transducer
专利汇可以提供Electro-acoustic transducer专利检索，专利查询，专利分析的服务。并且PURPOSE:To make pickup of vibration from both ears possible to improve sensitivity by making it possible to insert protrusions of a pair of ear pieces into left and right external auditory canals at a using time. CONSTITUTION:A pair of ear pieces 21 and 22 have protrusions 21a and 22a which can be inserted to external auditory canals respectively, and these ear pieces are fitted to ear muffs 9a and 9b as a pair of holding materials, which can be mounted on ears, through support materials 10a and 10b. Ear muffs 9a and 9b have ear cushions 11a and 11b, by which the use feeling for mounting is improved, in ear contact parts. These ear muffs are linked with each other by link material 12 so that protrusions 21a and 22a of ear pieces 21 and 22 may be opposite to each other at a prescribed interval. One piezo-electric element which converts, for example, vibration to an electric signal is incorporated in each of protrusions 21a and 22a of ear pieces 21 and 22.，下面是Electro-acoustic transducer专利的具体信息内容。
