摘要: The present invention relates to a miniature transducer assembly for a wireless portable terminal. The miniature transducer assembly of the present invention comprises a transducer unit comprising a number of voice coils for displacing a diaphragm of said transducer unit. Moreover, the transducer assembly comprises at least one de-coupling coil for avoiding interference between the transducer unit and an antenna of the wireless portable terminal. In order to reduce the dimensions of the transducer assembly at least one de-coupling coil forms an integral part of a lead-out wire from of a voice coil.
