Acoustic transducer with piezoelectric ceramic transducer built into vibrating diaphragm

摘要

The acoustic transducer (1) comprises a functional group (2), which functional group (2) comprises a diaphragm pot (6) and at least one electroacoustic transducer element (3). Furthermore, the acoustic transducer (1) comprises a housing (5). The diaphragm pot (6) comprises a vibrating diaphragm (8) and a surrounding wall (7) and at least one electroacoustic transducer element (3), which transducer element (3) excites the diaphragm (8). Configured to vibrate and / or convert vibration of the diaphragm (8) into an electrical signal. The diaphragm pot (6) is made of a plastic material, and according to the invention, at least one transducing element (3) is incorporated in the vibrating diaphragm (8), in particular without an additional adhesive layer, The element (3) is formed as a piezoelectric ceramic element.
