Abstract
The present disclosure provides an acoustic wave transducer and a driving method thereof. The acoustic wave transducer includes cell groups, at least part of which each include acoustic wave transducer cells configured to perform a same operation, each acoustic wave transducer cell being configured to perform at least one of: converting an acoustic wave signal into an electrical signal and converting an electrical signal into an acoustic wave signal; and array element signal terminals, each of which is coupled to at least two adjacent cell groups, and is coupled to different cell groups through different switch devices, each switch device being configured to control connection and disconnection between the array element signal terminal and the cell group coupled to the switch device, and the cell groups coupled to an array element signal terminal and the cell groups coupled to an adjacent array element signal terminal are partly the same.
