Abstract (en)
[origin: WO2019197149A1] The invention relates to a sound transducer for sending and/or receiving underwater sound signals, wherein the sound transducer comprises at least two sound transducer shells, each comprising a piezoceramic material and each being electrically conductive on an outer surface and an inner surface, the sound transducer shells forming a toroidal shape so that an underwater sound signal can be sent and/or can be received rotationally symmetrically. The invention also relates to an underwater antenna, a trailing antenna, a sonar for sending and/or receiving underwater sound signals, and a watercraft.
