A hydromassage bathtub with ultrasound micromassage system comprising a plurality of ultrasound emission devices (13, 113) distributed over the walls of the bathtub. The ultrasound emission devices (13, 113) comprise means (23, 26; 118, 125) for orientating the direction of emission of the ultrasounds into a wide beam, at least 10 cm. wide at a distance of 20 cm. from the source. In case of conical beam, the means orient the beam into a solid angle of not less than 30.degree. and advantageously at least 50.degree.. With one ultrasonic emitting element (24) inside the emission device the emission beam obtained is superior to the natural width or divergence of said element.
A hydromassage bathtub with an ultrasonic micromassage system comprising a plurality of ultrasound emitting devices distributed over the wall of the bathtub, and wherein each of the ultrasound emitting devices comprises orienting means for producing an ultrasonic beam which is at least 10 cm. wide at a distance of 20 cm. from the bathtub wall.
A hydromassage bathtub with an ultrasonic micromassage system comprising a plurality of ultrasound emitting devices distributed over the wall of the bathtub, and wherein each of the ultrasound emitting devices comprises orienting means for producing an ultrasonic beam which is at least 10 cm. wide at a distance of 20 cm. from the bathtub wall, and each of said devices including an ultrasonic emitter, said orienting means of each device comprising a surface which reflects the beam emitted by the associated ultrasound emitter.
A hydromassage bathtub with an ultrasonic micromassage system comprising a plurality of ultrasound emitting devices distributed over the wall of the bathtub, and wherein each of the ultrasound emitting devices comprises orienting means for producing an ultrasonic beam which is at least 10 cm. wide at a distance of 20 cm. from the bathtub wall, said orienting means comprising a support having mounted thereon a plurality of ultrasound emitters disposed to emit beams inclined at angles to one another.
