摘要 |
<p>Disclosed is an electroacoustic transducer of the electret type, wherein above a diaphragm (307) a backplate (305) is arranged, which backplate is provided with spacers (308). The diaphragm is clamped on a frame-shaped carrier (309) located at the underside of the diaphragm. The carrier is provided with supporting portions (330) which are aligned with the spacers (308). In one embodiment, supporting posts (551) are formed on the supporting portions to allow the carrier to rest on a case bottom (501a). The electroacoustic transducer according to the invention can be assembled more easily and with less risk of damage. <IMAGE></p> |
