Abstract

A method of making an acoustical member capable of supporting bending wave vibration comprising the steps of providing a panel (12) to form an acoustic radiator; identifying a position (14) on the panel (12) for mounting a vibration transducer (20) to excite bending waves in the panel and securing stiffening means (16) to the panel at the position (14) for mounting the transducer to stiffen the panel locally. A loudspeaker (10) comprising a bending wave panel-form acoustic radiator (12) and a vibration transducer (20) mounted to the panel (14) to excite bending-wave vibration in the panel, characterised by a stiffening member (16) which is secured to the panel locally of the transducer.
