摘要： An acoustic device and method of making said acoustic device. The acoustic device comprises a diaphragm (10) having resonant bending wave modes in the operating frequency range, and a plurality of electro-mechanical transducers (12) coupled to the diaphragm. The positioning and mechanical impedance of the transducers are such that at least a selected number of the resonant bending wave modes are balanced so that the net transverse modal velocity over the area of the diaphragm tends to zero with the balancing of the resonant bending wave modes being achieved substantially by the positioning and mechanical impedance of the transducers. The parameters of the diaphragm may be such that there are a plurality of nodal grouped locations at or around which the nodal lines of a selected number of resonant modes are clustered. Each transducer may be mounted at one of the plurality of nodal grouped locations.

摘要： A bending transducer (20) comprises an electrostrictive ceramic member (2) and electrodes (4, 5) for transmitting an electric field to or from said member and which do not contribute significantly to the bending stiffness of said electrostrictive ceramic member. At least one of the electrodes (4, 5) is capable of a yield strain significantly greater than that of the electrostrictive ceramic member (2); thereby accommodating any deformation of the electrostrictive member (2) that might cause a fracture of that member. In this way, electrical continuity is maintained. The bending transducer is suited to loudspeaker applications.
