本发明涉及一种用于发射和/或接收声信号的装置（1）。 该装置（1）包括电声换能器（2），所述至少两个相互电绝缘的第一触点（3A，3B，3C，3D），经由所述电声换能器（2）的可受激振荡的各个不同的区域， 其中，所述装置（1）在每个被施加的电信号在每种情况下，第一接触部（3A，3B，3C，3D），其特征在于，所施加的电信号具有相互不同的时间过程的适合于与一个传输声信号，并 在每种情况下的电信号抽头/或在每个第一触头（3A，3B，3C，3D）的接收声信号，以确定在抽头电信号的定时的差的电声换能器的振荡。

The present invention relates to a device (1) for transmitting and / or receiving acoustic signals. This device (1) comprises an electro-acoustic transducer (2), the at least two mutually electrically insulated first contacts (3a, 3b, 3c, 3d), via the respective different regions of the electro-acoustic transducer (2) can be excited to an oscillation, wherein the device (1) is adapted to that with a transmission acoustic signals at each of the first contacts (3a, 3b, 3c, 3d) is in each case applied an electrical signal, wherein the applied electrical signals have a mutually different time course, and / or at a receiving acoustic signals at each of the first contacts (3a, 3b, 3c, 3d) in each case an electric signal is picked up to be determined from the differences in the timing of the electrical signals tapped oscillation of the electro-acoustic transducer.
