<p>A moulded suspension (50) for an electro-acoustic transducer in the form of a microphone (16) or a receiver (17) has three regions. A transducer supporting region (51) fits closely around the transducer. A tubular inlet region (52) connects the acoustical inlet or outlet (16A, 17A) of the transducer to a respective port of the appliance containing the transducer. The third region is a tubular foot (53) which has an annular flange (54) so that the moulding can be mounted adjacent to an aperture formed in a supporting plate (20, 21). The suspension is made of an elastomeric material. It is particularly suitable for use in "behind-the-ear" hearing aids.</p> |
