发明名称 UN DISPOSITIVO TRANSDUCTOR ELECTRODINAMICO.
摘要 <p>An electrodynamic transducer of the flat-diaphragm type in which the movement of the voice coil and coil former (2, 3) is transmitted to the flat diaphragm (1) via at least one auxiliary cone (8 or 20). The auxiliary cone is secured to a centering diaphragm (7) along its outer rim (10), if required via a coupling element (23). This is advantageous in the construction and the method of manufacturing the transducer. Moreover, a low-distortion transducer is obtained. A method of manufacturing the transducer is disclosed.</p>
