FIELD: engineering of devices for generating mechanical oscillations in ultrasound spectrum. ^ SUBSTANCE: ultrasound emitter contains emitting plate with non-through hollow, in which a pin with rod is positioned, tightening the radial shelf of emitting plate and the tub wall through an elastic ring by means of a case. Reflecting plate, contacting piezo-ceramic rings through contact plates, is made with apertures for efficient suppression of resonance waves. ^ EFFECT: increased durability of device in optimal modes while preserving all positive properties of ultrasound emitter. ^ 2 dwg |
