Making contact with piezoelectric-acoustic transducers for electro-acoustic capsules

摘要

Piezoelectric-acoustic transducers normally have two small connection strips: one small strip makes a pressure contact onto the adhesive-side electrode of the piezoceramic part and the second is soldered onto the other electrode. The invention removes the need for soldering the small connection strip onto the ceramic plate. For this purpose, the force to make contact with the second connection element is derived from a connection element shape (for example a Z-shape) which produces a contact pressure, and the other end of the small connection strip is soldered onto the conductor track of an amplifier unit only if required. <IMAGE>
