Oscillator device and electronic apparatus
摘要:
In an electro-acoustic transducer 100 which is an oscillator device, center positions of principal surfaces of piezoelectric elements 130 that are positioned on both surfaces of an elastic member 120 are different from each other. As such, since the two piezoelectric elements 130 are disposed asymmetrically on the upper and lower sides in the electro-acoustic transducer 100, it is possible to prevent vibrations of reversed phases at the time of divided vibration in which the reversed phases overlap with each other. In other words, since it is possible to prevent the generation of sound waves due to the vibration of local reversed phases, the sound pressure level can be improved.
