Abstract

The unit is used for underwater massage in a bath and generates ultrasonic vibrations. It is powered by batteries, for safety reasons, and is held in the hand. The vibrations are produced by piezo-electric ceramic elements, the unit being sealed to prevent entry of water. An oscillator and an amplifier give very low kilohertz frequencies. The control system enables the state of the batteries to be determined, together with the correct operation of the unit. It comprises a lamp connected to the amplifier output and in parallel with the ceramic elements.
