摘要： A speaker gasket formed in a required shape out of elastic materials such as rubber has a plurality of bolt-through holes formed at regular intervals. The speaker gasket is formed with varying thicknesses, for example, in a such manner that the central portion in the width direction is formed with thickness greater or smaller than that of the portions on either side of the central portion; a plurality of recesses are formed; or the surfaces of the speaker gasket has a sawtooth waveform in the width direction.

摘要： A voice coil assembly for a speaker comprises a substrate, a spiral pattern coil formed on the substrate, at least one holder fixedly secured to the periphery of the substrate, and at least one metallic layer attached to said substrate. The metallic layer facilitates the dissipation of the heat generated by the voice coil, while a pair of metallic layers establishes electrical connections between the voice coil terminals and external terminal strips. The shape of the opening of the holder(s) may be made other than rectangular for avoiding the occurrence of standing waves which cause the frequency characteristic of the speaker to be deteriorated.
摘要翻译：用于扬声器的音圈组件包括基板，形成在基板上的螺旋图案线圈，固定地固定到基板周边的至少一个支架以及附着到所述基板的至少一个金属层。金属层有助于消除由音圈产生的热量，同时一对金属层在音圈端子和外部端子条之间建立电连接。保持器的开口的形状可以不是矩形的，以避免发生扬声器的频率特性恶化的驻波的发生。

摘要： An electroacoustic transducer includes: a diaphragm; a frame that is disposed around the diaphragm so as to surround the diaphragm; an edge that closes a space between the diaphragm and the frame in a manner of forming a membrane so as to connect the diaphragm and the frame; a base body that supports the frame and has a through sound output hole in front of the diaphragm; a magnet that is attached to the frame; and a voice coil body that is attached to the diaphragm. The frame has an annular first fitting portion that is disposed around the diaphragm so as to surround the diaphragm. The base body has a second fitting portion that fits with the first fitting portion. The electroacoustic transducer further includes a sealing member that is made of a thermoplastic substance and seals a space between the first fitting portion and the second fitting portion fitted with each other.
