Abstract
The oscillator consists of a U-shaped vibrating part (11) made from piezoelectric material having a pair of opposing limbs (11a, 11b) and a yoke (11c) connecting the limbs. Two electrodes (15a-f; 16a-f) are applied to the side faces of the vibrating part as a continuous, vapour-deposited layer. The connecting leads (17, 18) are constructed as flexible wires, and the vibrating member is held by a retaining device (13, 14). The connecting leads (17, 18) and the retaining device are connected, in each case in the region of the nodal point of the vibration, to the electrodes or to the vibrating member, in order not to influence the form of vibration of the vibrating member. <IMAGE>
