Abstract
The present invention relates to an electroacoustic transducer which is arranged in an acoustic track (AS) and on a piezoelectric substrate () and which has two electrodes () which are arranged on the substrate () and which have interengaging electrode fingers () for exciting acoustic waves. The electrode fingers () of an electrode () are interconnected. The transducer also has means for increasing the mass occupation in a central excitation region (ZAB) which runs parallel to the acoustic track (AS), and the mass occupation in the central excitation region (ZAB) is higher than in an edge region (RB) which adjoins the central excitation region (ZAB) from both sides.
