<p>An electro-acoustic transducer of dynamic type, particularly a small loudspeaker or microphone, such as a loudspeaker for use in headphones, comprises a magnetic circuit including an air gap, a diaphragm having a voice coil disposed in the air gap, and lead wires for the voice coil, the lead wires extending substantially tangentially from the voice coil and being bonded to the diaphragm by two different kinds of adhesive, a relatively hard adhesive being used near the voice coil and a relatively soft adhesive being used near the periphery of the diaphragm.</p> |
