Abstract:
1. An electroacoustic transducer with a transducer axis and comprising a membrane, which membrane is arranged perpendicular to the transducer axis so as to be oscillatory, wherein the membrane includes an intermediate area adjacent to a U-shaped peripheral area and an annular securing area adjacent to the intermediate area, and a central area located within the annular securing area, said central area serves for sound generation, and comprising a magnet system, which magnet system is equipped with two magnet-system components, which magnet-system components bound an air gap, and comprising a moving coil, which moving coil is, in part, arranged in the air gap and is connected to the membrane, and comprising a circuit module, which circuit module is equipped with a circuit frame and one single circuit component which forms a transducer circuit, the one single circuit component mounted on the circuit frame, the one single circuit component being an integrated circuit connected to the circuit frame, wherein the magnet system is arranged in an annular shape and encloses an inner space, which inner space is accessible from outside the magnet system during production of the transducer and before the circuit module is mounted, and wherein the at least one circuit component is arranged on a first carrier surface of the circuit frame which first carrier surface faces the membrane, and in the inner space of the magnet system.
