Description of the Invention (1)… Love: The field of the invention The present invention relates to flat speakers, especially, but not exclusively, I. yI— »(Please read the first; i (Please fill in this page for further information) About the flat-type loudspeaker described in my international patent application WO 97/09842 and is well-known as a distribution modal loudspeaker. Distribution mode speakers can cover the full range of sound in a single plane. Because the current state of the art in material technology will rule out the possibility of such a solution, my international patent application WO / 9709846 is to design a small distribution mode speaker plane suspended from a large distribution mode speaker plane with a low cut-off frequency. Internally, a speaker with a wide acoustic band width is produced. This design requires at least two appropriate types of exciters and careful design of the mechanical interface between the two planes. Because the two planes can cover a wide frequency range within their individual energies, there is also a wide frequency range within the output overlap of the two planes. Therefore, it is expected to have an electricity across the network ', although it will reduce the sound quality and increase the manufacturing cost. The object of the present invention is to provide a device which can alleviate or overcome these difficulties. General point of view of the Ministry of Foreign Affairs of the Central Ministry of Standards and Industry of China—In a conceptual aspect, the present invention may provide a planar speaker including at least two acoustic planes of a resonant distribution mode. A single exciter may be provided to Exciting all of the planes can thus effectively transmit the energy of the crossbow wave to each plane to stimulate the distribution mode resonance within it and thereby increase the output. Ideally, there should be two planes and the first plane should be larger than the other plane. The larger of the two planes is the best, and the smaller of the two planes has the low treasure curve hardness. The positioning of the smaller of the two planes is best offset from the relatively large plane of the paper.

Invention Explanation (2) '^ ~' 最佳 The optimal deviation of the position of the exciter relative to the center of the smaller of the two planes. According to an example, most smaller planes are combined with a single larger plane. The device is on the or each smaller plane, and the smaller plane is mated to the larger plane. The mating condition is such that the bending wave energy from each exciter and its associated smaller plane can be Effectively transfer to larger planes. The smaller and larger planes are best mated together face to face. The planes are fixed together by glue with low mechanical loss. According to another example, each smaller plane is formed Within the larger plane and mated to it, the exciter is mated to the smaller plane. One material can be used to complete the mating between the smaller and larger planes to form a restrained compliant joint. Then press another An example of the smaller plane system device at one end of the joint coupler 'light coupling passed The larger plane is connected to it, and the exciter is connected to the coupler. The exciter is best connected to the other end of the coupler. One material can be used to form one-gram compliant joint.

Description of the invention (3). The smaller plane (10) is a face-to-face mating to a larger distribution mode loudspeaker plane (14) of appropriate low hardness and orientation to properly cover the required low-frequency range. .By choosing the right materials and the design of the exciter, it can be shown that when the small plane (10) is excited, it can continue to produce its useful band width, which is superimposed on the low-range frequency output, so it can provide a relatively wide band width. Larger plane (丨 4). By applying a suitable adhesive with low mechanical loss, it can be matched with a smaller distribution mode speaker plane to a larger plane in order to maintain efficient transmission of mechanical energy at low frequencies while maintaining good high-frequency transmission. Capability and low loss. Epoxy resin is suitable for this The smaller plane (10) can be selected to fit into the larger plane (M) in accordance with the distribution modal principles described in our international patent application w〇 / 97 / 〇9842, just like the exciter ( 12) Fitted to the smaller plane (10). Figure 2 illustrates another type of planar loudspeaker according to the example of the present invention, in which a larger 'low-frequency optimal distribution mode plane (2 ... is added to a smaller plane) The high-frequency optimal plane (22) is formed in the region of the exciter (24). The common excitation point of the exciter (24) indicates that two parts or two areas of the plane can be excited. The additional hardening of the local chip collection area (26) can provide smaller, high-frequency parts or areas (please read the precautions on the back before filling this page) i-511 Printed by the Consumers' Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs Pretend to use the appropriate size paper I in the home country and the middle school.

Carbon fiber, glass fiber or similar high-strength substances. Just replace it by adding a new higher rigid skin section in the area. Available power depends on the natural balance of frequency distribution, depending on the characteristics of radio wave propagation in larger planes. Alternatively, a suitable compliant boundary (28) can be incorporated to distinguish between high and low frequency parts of the plane. The control of the elastic frequency-dependent amplitude reduction of the rebound coupling can be determined mechanically with the effective control of the amplitude reduction at the boundary between the two planes mechanically. Fig. 3 illustrates another type of flat speaker according to an example of the present invention. According to the device of Fig. 3, the high-frequency plane (30) is adhered and fixed on the light-weight tubular coupler (32). The coupler is mated to a plane as shown in (36) through a large, low-frequency plane (34) and is elastically connected. The elastic coupling of the coupler to the larger plane (34) acts as a mechanical low-pass filter to further define the energy balance between the two planes (30 and 34). It can be seen that the terminal of the coupler (32) separated from the high-frequency plane (30) is fixed to the exciter (38) of the exciter. Figure 4 illustrates another arrangement in the example of the present invention, in which a single-large resonance distribution mode acoustic f-plane (50) has been associated with many of its smaller planes (52) each having a joint exciter (54). Combine the smaller plane (52) with the larger plane (50) in the manner described in the modified figures 1 to 3. In other words, the smaller plane (52) is adhered face-to-face to the larger plane (50) and is also mounted on its own shaker. Alternately, the smaller plane (52) includes many sections of the larger plane (50), and the sections have been appropriately strengthened and provided with individual exciters (54). The strong section (52) is according to the reference The method described in Fig. 2 is coupled to a larger plane. Coincidentally, the smaller planes (52) include the planes' carried by the coupler. Each plane is associated with an individual exciter in the manner described in reference to Fig. 3. This shows that the smaller plane (52) in the device of Figure 4 (please read the precautions on the back before filling in this book)
