Abstract

PURPOSE:To carry out the support and wiring of a vibrator assembly by providing a socket with holds the vibrator assembly elastically. CONSTITUTION:Piezoelectrics 2a and 2b are stuck near base part 5 of vibrator 1 composed of a U-shaped metal plate. Here, 3a and 3b are insulators and piezoelectrics 2a and 2b are provided with conductive layers 4a and 4b. Socket 10 is provided with insulating poles 13a and 13b, conductive pole 12 is provided between both the poles, and conductive poles 14 and 15 are further provided on both the sides of pole 12. Inserting base part 5 of vibrator 1 makes electric connections between conductive layer 4a and conductive pole 14, conductive layer 4b and conductive pole 15, and the bottom surface of base part 5 and conductive pole 12 respectively while holding vibrator 1 by the elasticity of socket 10.
