Abstract: A moulded suspension for an electro-acoustic transducer in the form of a microphone or a receiver has three regions. A transducer supporting region fits closely around the transducer. A tubular inlet region connects the acoustical inlet or outlet of the transducer to a respective port of the appliance containing the transducer. The third region is a tubular foot which has an annular flange so that the moulding can be mounted adjacent to an aperture formed in a supporting plate. The suspension is made of an elastomeric material. It provides a high degree of vibration isolation and is particularly suitable for use in "behind-the-ear" hearing aids.
