<p>The massager consists of an electromechanical vibrator (11) formed by an electric motor (12) with two 10 - 40g weights (14, on the ends (18A, 18B) of its rotor shaft, and a feed circuit (42) with vibration frequency controller. The weights, designed to produce cycloid vibrations at amplitudes close to 1 mm, rotate in two cylindrical cavities (24, 26) inside protective covers (20 22), and the whole assembly is sealed inside an over-moulded shell (32) of an insulating resin material suitable for immersion i liquid such as water.</p> |
