Title: ACOUSTIC SENSOR WITH A HOUSING AND A MEMBRANE ELEMENT ARRANGED ON SAID HOUSING
Abstract:
The present invention relates to an acoustic sensor (1) comprising a carrier element (2), a membrane element (3), which is arranged on a first side of the carrier element (2), and an electroacoustic transducer (4), which is arranged on a side (4a) of the membrane element (3), said side being directed towards the carrier element (2), and is intended to cause at least one region of the membrane element (3) to oscillate, wherein, on at least one peripheral region (5), the membrane element (3) has a retaining region (6), which extends in the direction of the carrier element (2) and engages around a sub-region (7) of the carrier element (2).
