    摘要： A resonant bending wave loudspeaker comprising a panel-form acoustic radiator in the form of a beam and a vibration transducer mounted to the beam at a position to apply bending wave energy thereto to enable low frequency modes to be excited in the radiator both lengthwise of the radiator and crosswise of the radiator, and means mounting the radiator to permit the excitation of low frequency lengthwise and crosswise modes therein. From another aspect, the invention is a method of designing a resonant bending wave loudspeaker of the kind described above, comprising determining a position for locating the vibration transducer on the beam by deriving a model of the resonant modes in the beam from physical parameters of the beam, using the model to calculate the mechanical input power from the transducer to the beam as a function of frequency, calculating a measure of smoothness of the mechanical input power and selecting the position of the vibration transducer which has a desired value of the measure of smoothness.

    摘要： A panel form acoustic member capable of supporting bending wave vibration has the bending wave velocity varied in the region of coincidence to provide a range of coincidence frequencies, for causing the acoustic coupling of the bending waves in the panel to occur over a broader range of angles or for making the coupling more uniform. The member may be incorporated in a loudspeaker having a panel member (1) and an exciter (3) fixed to the panel member to excite bending waves in the loudspeaker to cause an acoustic output.

    摘要： Active acoustic device comprises a panel member (11) having distribution of resonant modes of bending wave action determining acoustic performance in conjunction with a transducer (31-34). The transducer (31-34) is coupled to the panel member (11) at a marginal position. The arrangement is such as to result in acoustically acceptable action dependent on said distribution of active said resonant modes. Methods of selecting the transducer location, or improvement by location of localized marginal clamping, rely on assessing best or better operative interaction of said transducer (31-34) and the panel members (11) according to parameters of acoustic output for the device as an acoustic radiator.
