Abstract

An electroacoustic transducer arrangement comprises a two-dimensionally extended electroacoustic transducer (101), which has a main surface (103), which in a first state is convex and in a second state is concave. The electroacoustic transducer arrangement comprises a flexible surround (102), which extends axially away from the main surface (103) of the electroacoustic transducer (101), wherein a region (104) of the surround (102) that is remote from the electroacoustic transducer (101) is inclined inwards when the electroacoustic transducer (101) is in the first state relative to a position of the region (104) of the surround (102) that the surround (102) has when the electroacoustic transducer (101) is in the second state.
