DEVICE FOR TRANSMITTING ACOUSTIC SIGNALS IN A PRIMARY DIRECTION AND/OR RECEIVING ACOUSTIC SIGNALS FROM THE PRIMARY DIRECTION

摘要

The invention relates to a device (1) for transmitting acoustic signals in a primary direction (2) and/or receiving acoustic signals from the primary direction (2), in particular in order to sense a vehicle environment, comprising an electroacoustic transducer (3) and a deflecting element (4). The electroacoustic transducer (3) is designed, when acoustic signals are transmitted, to transmit the acoustic signal in the primary direction (2) and a backward direction (5) and/or, when acoustic signals are received, to be excited by the acoustic signal from the primary direction (2) and from the backward direction (5). The deflecting element (4) is designed, when acoustic signals are transmitted, to deflect the acoustic signal output in the backward direction (5) into the primary direction (2) over a first acoustic path (6) in such a way that said acoustic signal passes the electroacoustic transducer (3) to the side thereof and/or, when acoustic signals are received, to deflect the acoustic signal, which arrives from the primary direction and passes the electroacoustic transducer (3) to the side thereof, over the first acoustic path (6) in such a way that said acoustic signal hits the electroacoustic transducer (3) from the backward direction (5).
