摘要： A loudspeaker is made of a panel (1) supporting bending waves and a transducer (3) covering a substantial portion of the panel surface. At least one constraint, for example a clamp or a mass, is fixed to the panel. Each constraint reduces the mobility of a small area of the panel. Excitation of the transducer excites bending waves in the panel; the constraints discourage simple motion and encourage the production of a plurality of bending waves instead. The constraints can constrain the panel to be excited to produce a good distribution of resonant bending wave modes.

摘要： A method of reducing features occurring at particular frequencies such as at coincidence is described. A panel (11) has exciters (13, 15) arranged to reduce the feature. The exciters may be driven in phase but be spaced apart by a distance substantially equal to half the wavelength of bending waves in the panel at this particular frequency.

摘要： A rectangular, polymorphous or elliptical loudspeaker which is flat and has one or more flat diaphragms 14, 15 made of paper, double skinned fluted polypropylene copolymer, corrugated cardboard, layers of EVA (Ethlene-Vinylacetate), EPS (Polyform), PVC (Polyvinyl Chloride). The panel has a longitudinal bending strength greater than the transverse bending strength. The diaphragm is vibrated by a driver unit 16 which comprises a magnet 17 and voice coil 18. Magnet 17 can be mounted on the rear panel 15 and the voice coil 18 is mounted on the front diaphragm 14. An alternative is to mount magnet 17 on the rear diaphragm instead of panel. The diaphragm 14 is mounted at its edges to a frame 11 with the driver unit 16 mounted in the space enclosed by the frame and the panel 15.

摘要： A method of operating a resonant panel-form loudspeaker, comprising arranging the loudspeaker panel near to a boundary so as to be acoustically linked to the boundary and with the plane of the loudspeaker panel at an angle to the boundary. The method may comprise moving the panel between a rest position in which the panel is parallel to and adjacent the boundary and a position of use in which the panel is at an angle to the boundary. A resonant panel-form loudspeaker support comprising means engaging and retaining the loudspeaker panel to be supported, means adapted for engagement with, and fixing to, a boundary, e.g. a wall or ceilling, and means connecting the respective loudspeaker and boundary engagement means, whereby the loudspeaker is supported adjacent to the boundary and at an angle thereto and such that the loudspeaker is linked acoustically to the boundary. The combination of a resonant panel-form loudspeaker and a support as described above.

摘要： The invention relates to so-called panel loudspeakers (11) working according to the multiresonance principle. Said loudspeakers are generally formed by a core layer (13) and at least one outer layer (14.o, 14.u). The outer layers (14.o, 14.u) are connected to the core layer (13). A periphery is also provided (12) enclosing the panel loudspeaker (11) at a lateral distance (A). The panel loudspeaker is connected to the periphery (12) by means of connecting elements (17, 17'). Although good reproduction results can be obtained in the mid and high audio frequencies with the panel loudspeakers (11) described above, undesired large panel surfaces are known to be required for good low frequency reproduction. When such panel surfaces are not used, the lowest panel resonances ensuring bass reproduction are shifted towards the midfrequencies. Hence, the invention aims at providing a panel loudspeaker (11) exhibiting improved acoustic reproduction in the low frequency range despite a relatively smaller panel surface. According to the invention, this is achieved in that the connecting elements (17 17') are subjected to mechanical tension when they are connected to the periphery (12) resulting in supplementary particularly low frequency drum resonances in addition to the existing low frequency panel resonances, which can be modulated by the tension in the connecting elements (17, 17').

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 transducer means (31-34). The transducer means (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 localised marginal clamping, rely on assessing best or better operative interaction of said transducer means (31-34) and the panel members (11) according to parameters of acoustic output for the device as an acoustic radiator.

摘要： Erfindungsgemäß wird eine Anschlußkontaktierung für Schallwiedergabeanordnungen nach dem Biegewellenprinzip angegeben. Da die Antriebssysteme 21 solcher Anordnungen hohe Stromstärken erfordern und solche Stromstärken nur von massiven, aber die Biegewellenausbreitung behindernden Anschlußkontaktierungen sachgerecht übertragen werden konnten, war Aufgabe der Erfindung, eine Anschlußkontaktierung anzugeben, welche die Probleme im Stand der Technik beseitigt und außerdem sehr einfach realisiert werden kann. Hierzu wird angegeben, daß wenigstens eine der beiden Deckschichten 12 und / oder die Kernschicht 11 leitfähig Bereiche 17 aufweist, die mit den Leitungen 32 einer Tonsignalquelle verbunden sind. Besonders vorteilhaft ist es, wenn die leitfähigen Bereiche 17 zusammen mit den Komponenten herstellt werden können, die auch sonst zur Herstellung der Kernschicht 11 verwendet werden.
