A piezoelectric generator of mechanical oscillations comprises a piezoelectric ring polarized transversely to ring faces, two thin-wall ring-like electrodes located on ring’s faces that have means for connection to a pulse current source, a subsidiary ring-like metallic resonator located from side of a flat ring and equipped in peripheral aria at least one bent resilient pusher for rotation of a rotor of the piezoelectric generator, a ring-like sound-conducting laying between a subsidiary resonator and one of ring-like electrodes, an outer diameter of the said laying does not exceed an outer diameter of the subsidiary generator, and a means for compression of these details in an acoustical dense pack. The piezoelectric motor comprises a body, a sound-insulated stator rigidly connected with the body, at least one piezoelectric generator of mechanical oscillations and the rotor with an output shaft. |
