Abstract

In an apparatus (1) having a housing (2) and having an electroacoustic transducer (14) accommodated in the inner housing space (9) and having at least one passage (28, 29) which traverses a housing wall (6, 7) and which, together with the inner housing space (9) and the rear volume (25) of the transducer (14), which rear volume (25) is open to the inner housing space (9), forms an absorption-circuit resonator which causes a dip (31) in the sound pressure versus frequency response (27), compensation means (32) for the compensation of the dip (31) in the sound pressure versus frequency response (27) have been provided, the housing (2) being provided with a plurality of ducts (33, 34, 35, 36; 41) to form the compensation means (32), which ducts traverse the housing (2) and each forms an acoustic friction.
