Abstract

PURPOSE:To obtain a quick response in a simple constitution, by opposedly and adjacently providing an optical fiber which is so set that the exit side of light may vibrate responding to the incident sound wave and a fixed fiber. CONSTITUTION:The light radiated from a light emitting device 5 is caused to enter both ends of one side of an optical fiber 6, and it is so set that this light may leave an exit plane 63 and enter an optical fiber 7. When sound is emitted in this state, the sound is transmitted to the fibers 6, 7. Of the fiber 6, the part 62 mechanically fixed by a clamp 10 does not vibrate, but since the end part 61 is not fixed, the end vibrates responding to the sound wave. As a result, the exit plane 63 and fiber 7 may be deviated in axis due to vibration, so that the intensity of light entering the fiber 7 may be modulated in response to the sound.
