摘要： A low cost dynamic speaker (10) prevents damage of the diaphragm (16) when the speaker (10) is mounted on a printed circuit board (2). An insulating ring (22) is attached to the front surface of the diaphragm (16) at the periphery. The insulating ring (22) has a pair of terminal pins (24) supported thereon for continuity of the lead wire (18a) with the conductor (4) of the printed circuit board (2). The conducting portion (24b) of each of the terminal pins (24) is protruded forward beyond the annular flat surface (22a) of the insulating ring (22).

摘要： Fixing of a voice coil (16) to a diaphragm (12) is performed by caulk-fixing a coil supporting member (26) to the diaphragm (12) and by fit-supporting the voice coil (16) by the coil supporting member (26). Hereby, the voice coil 16 is physically fixed to the diaphragm (12) and its fixing strength is heightened. The caulk-fixing is performed by subjecting a caulking projection of the coil supporting member (26) to a plastic deformation thereby to provide a caulk-fixed portion (26b), whereby deformation injurious to the acoustic property does not occur in the diaphragm (12). Further, the fit-supporting is performed by interposing a flange portion (16a1) formed at an upper end portion (16a) of the voice coil (16) between an engaging portion (26a) of the coil supporting member (26) and a central flat portion (12b) of the diaphragm (12) and holding it by them from upper and lower sides.
摘要翻译：音圈（16）固定在隔膜（12）上是通过将线圈支撑构件（26）固定在隔膜（12）上并通过线圈支撑构件（16）将音圈（16） 26）。因此，音圈16物理地固定在隔膜（12）上，其固定强度提高。通过对线圈支撑构件（26）的铆接突起进行塑性变形从而形成填缝固定部（26b）来进行铆接固定，由此在隔膜（12）中不会发生对声学特性有损害的变形）。此外，通过将形成在音圈（16）的上端部分（16a）处的凸缘部分（16a1）插入在线圈支撑构件（26）的接合部分（26a）和中心隔膜（12）的平坦部分（12b）并且由它们从上侧和下侧保持。

摘要： In an electroacoustic transducer, a pair of coil terminals elongating from a voice coil are electrically connected to a pair of terminal members attached to a frame via a flexible printed circuit board, respectively. According to the configuration, even in a case where an electroacoustic transducer is used at a high sound pressure, breakage of the coil terminals hardly occurs. In the flexible printed circuit board, the width of an intermediate portion is set to be smaller than the widths of an end portion on the side of the coil terminals and an end portion on the side of the terminal members. Therefore, the flexibility of the intermediate portion can be enhanced, whereby transmission of characteristic vibration of the flexible printed circuit board to a diaphragm, and stress concentration in the vicinity of the end portions are effectively suppressed.

摘要： By forming a flange portion (16a1) protruding inward in the radial direction at an upper end portion (16a) of a voice coil (16), a coiling sectional shape of the voice coil (16) is set to a L-shape. And, the upper end portion (16a) of this voice coil (16), is bonded and fixed to a central flat portion (12b) of a diaphragm (12). Hereby, by only increasing slightly the weight of the usual voice coil having an I-shaped coiling section, the large bonding area can be obtained between the voice coil (16) and the diaphragm (12), so that separation of the voice coil (16) can be prevented. Further, since other portions of the voice coil (16) than the upper end portion (16a) thereof have the usual coil thickness, it is not necessary to expand the width of a cylindrical magnetic gap G in a magnetic circuit unit (18), whereby it is prevented that electroacoustic conversion efficiency of a speaker (10) lowers.
