ABSTRACT:
A transducer which is particularly suitable for hearing aids is set forth which has improved resistance to mechanical shock. The transducer includes a coil having a tunnel, a magnetic member with a pair of magnets defining an air gap and an armature extending through the tunnel and into the air gap. The coil is rotated with respect to the magnetic member in a manner such that the coil forms a stop for the armature, thus preventing excessive deflection of the armature leg in the occurrence of a shock. The armature may also be provided with expanded edge portions which assist in limiting its deflection.
