Piezoelectric vibrator |
摘要 |
A piezoelectric vibrator adapted to operate in a spreading vibrating mode comprises compensation parts for compensating for the non-vibratory, or dead, region of a piezoelectric element which is formed between two confronting coupling pieces. The compensation parts comprise peripheral parts of the piezoelectric element that extend in an non-uniform manner from a center line passing through the respective centers of the confronting coupling pieces.
