Abstract

PURPOSE:To make it possible that an electroacoustic transducer has an arbitrary frequency characteristic adapted to use purposes, by sticking an adjustng material to the outside circumference part of the vibrating material spread over the aperture face of the fixing material. CONSTITUTION:One vibrating piece 2 of of tuning fork type crystal vibrator 1 is fitted to substrate 4 through fixing stand 3 consisting of insulating materials, and handle part 5 corresponding to the node of vibration and the other vibrating piece 6 are supported above substrate 4, and lead wires 7 and 8 led out from a pair of electrodes of vibrator 1. Clindrical material 9 is caused to adhere to the peripheral part of substrate 4, and vibrating material 10 is stuck to the aperture face to seal the box hermetically. Further, the center corresponding to the belly of vibration of vibrating material 10 and the tip part of vibrator 6 are linked with each other by linking material 11. An adjusting material such as a rubber plate is stuck to the outside circumference of vibrating material 10. As a result, the upper limit of the frequency band of this electroacoustic transducer can be extended to a high-frequency band.
