ABSTRACT:
An object of the present invention is to provide an electro-acoustic transducer having the effects of absorbing vibration and high-frequency noise, reducing the number of components, and preventing heat conduction at the same time. An electro-acoustic transducer according to the present invention includes: an electrically conductive capsule having an opening for electrically connecting internal circuitry to an external object; terminals which protrude from the opening to the outside; and a raised part which is a portion of the capsule on the opening side and is spaced with a gap from the internal structure of the capsule. The raised part and the terminals are arranged in such a manner that the raised part and all of the terminals are able to be directly soldered to a wiring board. The raised part may extend toward the terminals in such a manner that the opening is narrowed. Furthermore, the raised part may have a slit extending to the boundary between the raised part and the other part of the capsule.
