    • 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.
    • 本发明的目的是提供一种具有吸收振动和高频噪声,减少部件数量以及同时防止热传导的效果的电声换能器。 根据本发明的电声换能器包括:导电胶囊,具有用于将内部电路电连接到外部物体的开口; 从开口向外突出的端子; 以及作为开口侧上的胶囊的一部分并且与胶囊的内部结构间隔开的凸起部分。 凸起部分和端子被布置成使得凸起部分和所有端子能够直接焊接到布线板。 凸起部分可以以开口变窄的方式朝向端子延伸。 此外,凸起部分可以具有延伸到胶囊的凸起部分和另一部分之间的边界的狭缝。
