In the case of an electroacoustic transducer, in particular for underwater use, having a ceramic body (10) and a pair of electrodes, whose flat electrodes (11, 12) are arranged on mutually averted end faces (101, 102) of the ceramic body (10), at least one electrode (11) is structured in order to effectively suppress the sidelobes in the direction characteristic for all spatial directions such that the density of the ceramic body (10) decreases from the body centre to the body edge (Figure 1). |
