Definitions
- Connection layer is electrically conductive.
- it comprises a conductive second adhesive layer.
- conductor tracks are arranged within the terminating layer, which contact the second electrodes.
- each piezoelectric element 105 at least partially on the
- Piezo elements 105 a lateral distance which is less than half the airborne sound wavelength of an operating frequency of the sound transducer assembly.
- the operating frequency is in the range of 20 kHz to 150 kHz, preferably 50 kHz.
- the acoustic transducer arrangement comprises between two and fifty piezoelectric elements 105, preferably two to twelve.
- the piezo elements 105 are arranged in the form of an array.
- the array may be linear, matrix-like, oval or circular.
- the Schallwanlderanssen is in motor vehicles, moving or stationary
- Piezo elements is an electrically conductive second connection layer, also preferably an adhesive layer, applied to the bearing surfaces.
- first recesses of the perforated plate carrier are at least partially filled with a damping material.
