Abstract
Spray device comprising a piezoelectric element, a sonotrode having a base coupled to the piezoelectric element, and a tube extending as far as a horn, a drive circuit for vibrating the piezoelectric element, and a feed device for bringing the product to be sprayed up to the front face of the horn. The sonotrode mainly vibrates in a mode parallel to the tube, the horn being dimensioned so as not to flex along the longitudinal axis, without flexing when the drive circuit vibrates the piezoelectric element. This spray device is applicable in cosmetology and in perfumery.
