SIGNAL TRANSMITTER DEVICE COMPRISING AN ELECTRICAL ACOUSTIC SIGNAL TRANSMITTER |
摘要 |
A signal transmitter device comprises an electrical acoustic signal transmitter signal, which has a piezoceramic disk on a metal membrane, on a printed circuit board. The printed circuit board has an opening in the region of the piezoceramic disk or the metal membrane, wherein the metal membrane extends over the opening for the purpose of bearing on the printed circuit board in an edge region of the opening. The piezoceramic disk arranged on the metal membrane is arranged towards the opening and substantially in the region of the opening, wherein a contact projection as part of the printed circuit board for electrical contact-connection to the signal transmitter is provided at the edge region of the opening. Separate parts can thus be obviated.
