A bending vibration transducer 10 comprises a primary piezoelectric element 16 and a secondary piezoelectric element 18 having at least one end aligned with an end of the primary element 16. The aligned ends of the primary and secondary elements are attached using connecting means (14). The transducer is coupled to a load 12, e.g. a loudspeaker, using coupling means (20) which are attached only to the primary piezoelectric element 16. The secondary element 18 may lie below the primary element 16, or to the side (see figs 6,7a). |
