Patent ID: 8636750

Claim:
A device for removing hair, comprising: a vibratory unit having an ultrasound transducer element, a vibrating element and an acoustic horn between said transducer element and said vibrating element, wherein vibratory motion of said transducer element is transferred by said horn to said vibrating element; and a biasing unit having a gripping element and an actuator mechanism configured for closing and opening said gripping element onto said vibrating element, said actuator mechanism being operative to establish a linear motion of said gripping element along said horn such that a linear motion along a first direction opens a gap between said gripping element and said vibrating element to receive hair shafts in said gap, and a linear motion along a second direction, opposite to said first direction, closes said gripping element on said vibrating element so as to grip said hairs therebetween and to transfer said vibratory motion to said hair shafts for generating ultrasound wave therein.
