Abstract

An electromechanical transducer device includes a casing having a distal end and a proximal end, and an acoustic wave generator disposed inside the casing for generating an acoustic type vibration in response to an electrical signal. The acoustic wave generator having an axis extending between the proximal end and the distal end of the casing. An electrical transmission lead is mounted to the casing and is operatively connected to the acoustic wave generator for transmitting an electrical signal to the acoustic wave generator to energize the generator. A wave transmission member is in acoustic contact with the acoustic wave generator for transmitting the vibration from the acoustic wave generator to an active point outside the casing. The wave transmission member includes a stud which defines a fluid guide channel with a continuous wall extending axially through the acoustic wave generator from the active point to the proximal end for guiding fluid between the active point and the proximal end during operation of the acoustic wave generator. Mounting elements are provided for mounting the wave transmission member to the casing, the mounting elements including means for acoustically…
