    摘要： A loudspeaker includes a box-form structure made from stiff lightweight sheet material to define a plurality of faces, at least one face of the structure forming a panel-form bending wave acoustic radiator, and an electro-acoustic vibration transducer coupled thereto to apply bending wave energy to the radiator to cause it to radiate an acoustic output when an input signal is applied to the transducer. The box-form structure is collapsible, so that the box-form structure can be stored and transported in a flat form and erected as a box when required as a loudspeaker.

    摘要： A loudspeaker includes an assembly of at least two bending wave panel-form acoustic members each having a set of modes which are distributed in frequency. The parameters of at least two of the acoustic members are selected so that the modal distributions of each acoustic member are substantially different. The arrangement is such that the modal distributions of the assembly of acoustic members are interleaved constructively in frequency. A transducer applies bending wave energy to the acoustic members to cause them to resonate to produce an acoustic output. A method of making such a loudspeaker is also provided.

    摘要翻译： 扬声器包括至少两个弯曲波形面板形式的声学构件的组件，每个具有频率分布的一组模式。 选择至少两个声学构件的参数，使得每个声学构件的模态分布基本上不同。 这种布置使得声学构件的组件的模态分布在频率上被建设性地交织。 传感器将弯曲波能量施加到声学构件以使其谐振以产生声输出。 还提供了制造这种扬声器的方法。
