PURPOSE:To obtain a minimized and light-weight piezo-electric type ribbon microphone by forming a microphone by using a bimorph-type ribbon vibrator made of a highmolecular piezoelectric film. CONSTITUTION:A bimorph-type ribbon vibrator 1 is made of a high-molecular piezo-electric film. Both ends of the vibrator 1 are held by a ribbon holding body 2, and lead wires 3 which lead the output voltage from the both faces come out. The outer edge of the ribbon holding body 2 is supported by a frame 4 which encloses the vibrator 1 and the whole ribbon holding body 2. Such a formation makes it possible to have a minimized and light-weight piezo-electric type ribbon microphone. |
