摘要： Circular flat panel loudspeaker comprising a resonant with a rear surface opposite the front surface. An exciter is provided at an axial centre of panel and coupled to the rear surface of the panel to cause the panel to vibrate, on operation of the exciter, to generate sound. A frame is provided for mounting in the surface and having the rear surface of the panel fixed thereto around the whole of the outer boundary of the panel, such that when mounted in the mounting surface and when the panel is caused by the exciter to vibrate on operation of the exciter, the outer boundary of the panel is fixed relative to the mounting surface. Means are provided to induce non-circularly symmetric distortion of natural modes of oscillation of the panel, the support frame and the exciter absent the mode distribution means

摘要： The present application provides a method of manufacturing a resonant panel (200) of a flat panel loudspeaker. The method comprises: pressing a resonant panel blank between a first pressing surface (302) and a second pressing surface of a press, whereby to form the resonant panel (200) of the flat panel loudspeaker. The second pressing surface substantially opposes the first pressing surface (302). The first pressing surface (302) comprises at least one tool relief region (306, 312, 314, 316, 318), whereby to form at least one corresponding respective panel relief region (206, 212, 214, 216, 218) in a surface of the resonant panel (200).

摘要： There is provided a flat panel loudspeaker comprising a resonant panel, an exciter comprising a foot generally cylindrical in shape, coupled to the resonant panel and defining an inner region of the resonant panel. The exciter is drivable to vibrate the resonant panel via the foot, whereby to produce a sound. A stiffness of the resonant panel in the inner region is greater than a stiffness of the resonant panel in a region of the resonant panel outside the inner region. Additionally or alternatively, the flat panel loudspeaker further comprises a damping member in contact with the inner region of the resonant panel and arranged inside the foot to generally brace against the vibration of the resonant panel so as to damp a response of the resonant panel in the inner region to a vibration from the exciter.

摘要： A flat panel speaker comprises a mounting unit for mounting inside the surface and having a front and a back; a speaker unit having a flat panel, wherein the speaker unit is seated in the mounting unit and at least partially extending frontwardly from the front of the mounting unit; and at least one holding portion arranged for extending frontwardly outwards past the speaker unit and to be usable to hold the flat panel speaker in the surface during mounting. A method of mounting the flat panel speaker in a surface is also disclosed, comprising: inserting the mounting unit of the flat panel speaker through an opening defined in the surface; using the at least one holding portion to hold the flat panel speaker in the surface during mounting; and securing the mounting unit to the surface, whereby to hold the flat panel speaker in place in the surface.
