机译:反噪声电极拾取

摘要

A noise canceling pickup with an electret is provided with a cylinder body having a front cover and a rear cover, said front cover is provided with sound passing holes, said cylinder body is provided with an oscillating membrane of the electret, a back electrode sheet and a back electrode base, wherein said cylinder body is composed of a front cylinder body and a rear cylinder body, said oscillating membrane is provided into said front cylinder body, said rear cover of said cylinder body is provided with at least one sound passing hole, and said rear cover is provided with electric elements therein. With the arrangement according to the present invention, the distance between the opposite front and rear sound passing holes can be made smaller. The noise canceling pickup with an electret can be used in the higher frequency band and in a wide frequency range to cancel the noises more effectively.
