Abstract

The transducer, e.g. for a telephone earpiece or microphone, has a centre pole shoe (2), front shoe (1), rear shoe (3), a permanent magnet (4) and a coil (13). - The assembly is held together by forming a plastics material or soft metal (7) around the centre pole shoe and the outer periphery of the units. ADVANTAGE - Simplified mfr. of units and thus costs. (First major country equivalent to HU-051438) (5pp Dwg.No.1/2)
