Abstract
Element for reproducing and/or recording sound, consisting of a membrane (3) which is equipped with a piezo-electric element (5), electric connecting means (6) working in conjunction with the piezo-electric element (5) and a housing (2) for the membrane (3), characterized in that the element (1) contains a wall part (17) situated at a short distance (D1) from the membrane (3), such that the sound vibrations which are generated by the membrane (3) are damped.
