Abstract

PURPOSE:To increase the sensitivity of the speaker through a simple constitution by linking the film to which the tension is given by the stretch ring provided at the edge of the speaker and the driving substance which vibrates by the signals via the connector. CONSTITUTION:The magnetic circuit is composed of magnet 1, pole piece 2 and yoke 3, and voice coil 4 is provided between piece 2 and yoke 3 to form a driving substance. Then frame 8 is sealed to the edge of yoke 3, and stretch ring 9 is buried at the upper rim of frame 8 via elastic substance 10 is order to stretch film 6 of polyester opposing to coil 4. After this, coil 4 is connected to film 6 via connector 5 made of the cone paper, and these objects are adhered to frame 8 via damper 7. Thus the resonance is caused at the joint between connector 5 and film 6 to the high frequency, and entire film 6 has resonance to the low frequency. As a result, the sensitivity can be increased for the speaker.
