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.

1. A signal transmitter device comprising: an electrical acoustic signal transmitter having a piezoceramic disk on a metal membrane, and comprising a printed circuit board, on which said signal transmitter is arranged,wherein said printed circuit board has an opening in a region near said piezoceramic disk or said metal membrane,wherein said opening has an edge region around said opening and said metal membrane substantially extends over said opening for the purpose of bearing on said printed circuit board in said edge region,wherein said piezoceramic disk on said metal membrane is arranged in a region of said opening and said piezoceramic disk is directed towards said opening,wherein a contact projection for electrical contact-connection to said signal transmitter is provided at said edge region of said opening, andwherein said contact projection projects from said printed circuit board and is formed by a projecting part of said printed circuit board. 2. The signal transmitter device according to claim 1, wherein said metal membrane substantially covers said opening in said printed circuit board and rests on a ring electrode extending around said opening, wherein said metal membrane is electrically connected to said electrode as a connection to said signal transmitter. 3. The signal transmitter device according to claim 2, wherein said metal membrane completely covers said opening in said printed circuit board and rests at said edge region on said ring electrode extending around said opening. 4. The signal transmitter device according to claim 1, wherein said contact projection is in the form of a bar or nose-piece and projects into said opening. 5. The signal transmitter device according to claim 1, wherein said contact projection projects into said opening by approximately 10% to 50% of the diameter of said opening. 6. The signal transmitter device according to claim 4, wherein said contact projection comprises an end region having a contact zone for bearing against and making an electrical contact-connection to said piezoceramic disk. 7. The signal transmitter device according to claim 1, wherein said electrical contact-connection to said piezoceramic disk is provided with a plated-through hole through said printed circuit board to a contact zone or a conductor track on an other side of said printed circuit board. 8. The signal transmitter device according to claim 7, wherein said plated-through hole is provided in a region of said electrical contact-connection to said piezoceramic disk and penetrates through said contact projection. 9. The signal transmitter device according to claim 1, wherein said electrical contact-connection on said contact projection to said piezoceramic disk is formed without through-plating onto an other side of said printed circuit board and runs on a side of said printed circuit board, wherein a conductor track from a contact zone on said contact projection to said piezoceramic disk to an electrical connection is provided with an insulating cover, at least in a region in which said metal membrane projects beyond said piezoceramic disk runs over said conductor track. 10. The signal transmitter device according to claim 9, wherein said insulating cover covers said conductor track at least over the length of said contact projection. 11. The signal transmitter device according to claim 1, wherein in a region of a transition of said contact projection to said edge region of said opening of said printed circuit board an incision is provided on both sides of said contact projection into said printed circuit board thereby lengthening said contact projection and increasing its flexibility. 12. The signal transmitter device according to claim 11, wherein each said incision has between 50% and 300% of the length of said contact projection into said opening. 13. The signal transmitter device according to claim 1, wherein said opening in said printed circuit board and said piezoceramic disk have a substantially corresponding form. 14. The signal transmitter device according to claim 13, wherein said piezoceramic disk is arranged concentrically with respect to said opening in said printed circuit board. 15. The signal transmitter device according to claim 1, wherein a drive circuit for driving said signal transmitter is arranged on said printed circuit board at a small distance from said opening. 16. The signal transmitter device according to claim 15, wherein said small distance is approximately of the order of magnitude of the diameter of said metal membrane. 17. The signal transmitter device according to claim 15, wherein said drive circuit is arranged on the same side as said metal membrane on said piezoceramic disk. 18. The signal transmitter device according to claim 1, wherein said piezoceramic disk has a thickness of approximately 30 μm to 150 μm, wherein it is printed or vapor-deposited as a layer onto said metal membrane. 19. The signal transmitter device according to claim 1, wherein a resonator housing is provided over said metal membrane and said piezoceramic disk.
