Electroacoustic transducer with built in transducer circuit

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.
