摘要：
In an electroacoustic transducer (1), an annular shaped magnet system (14) is provided, enclosing an inner space (22), in which inner space (22) an integrated circuit (31) is accommodated, with the aid of which integrated circuit (31) an electrical signal to be sent to a moving coil (29) of transducer (1) can be amplified.
