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： An acoustic test apparatus, comprises an input, for receiving electrical signals; a first acoustically sealable enclosure; a second acoustically sealable enclosure; an acoustically sealable test volume, located between the first and second acoustically sealed enclosures; a first electroacoustic transducer, mounted between the first acoustically sealable enclosure and the acoustically sealable test volume; and a second electroacoustic transducer, mounted between the first acoustically sealable enclosure and the acoustically sealable test volume. The input is connected to the first and second electroacoustic transducers such that an electrical signal from the input causes each of the first and second electroacoustic transducers to generate variations in sound pressure in the test volume, and wherein said variations in sound pressure generated by the first and second electroacoustic transducers are in phase with each other.
