Abstract

PURPOSE:To price low a vibrator made of a constantly-elastic material by using a polymer piezoelectric film as a driving piezoelectirc material. CONSTITUTION:To vibrating reed 10 made of a constantly-elastic material such as Elinvar, uniaxially-rolled film 11 of vinyliden polyfluoride, a polymer piezoelectric material is bonded and on it electrode film 12 is formed. With this film provided with an electric field as shown by arrow 13, vibrating reed 10 expands and contracts, causing inflection vibration. In this way, using a film as a driving piezoelectric material simplifies manufacture operation and also shortens the operation time of it. Consequently, a low-priced vibrator can be obtained.
