摘要： A method of improving the modal resonance frequency distribution of a panel (2) for a distribution resonant mode bending wave acoustic device involves analysing the distribution of the modal resonance frequencies of the panel, identifying a modal resonance frequency that is non-uniformly spaced relative to adjacent modal resonance frequencies, identifying a location on said panel that exhibits anti-nodal behaviour at said modal resonance frequency and changing the local impedance to bending wave vibration at said location (6). The method has particular application to distributed mode loudspeakers (1).

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.
