Abstract
An assembly (38) comprises a vibration transducer (50) coupled to a substrate (58) which incorporates a circuit (62) electrically connected to the transducer (50). The substrate (58) is adapted to be coupled to a bending wave member (30) for converting actuator vibration into acoustic radiation or vice versa and has sufficient flexibility to allow bending wave coupling between the substrate (58) and the member (30).
