Description of the invention (3) The low vibration energy in the suspension area is better than other possible methods, which is conducive to the use of stronger suspension components, so it can increase the durability of the finished assembly. / Flexible suspension system can be made by cutting the board to form a finger-shaped cantilever member with the board-body. The cutting system may include a parallel pair of slots through the plate structure. Cantilevered members can be straight or curved. When considering the use of a suspension as an oscillator, a 'straight cantilever-type member system is the best, because it is easy to cross the low average speed region and the distance that the oscillator is coupled to the high-effect section of the board. The release system may include a set of such cantilevered members. Therefore, the board can be cut into cantilever members that retain the strength of the board and formed in the board-a frame or a support. Another way—or another independent flexible suspension—such as a rubber-like material bonded with an adhesive is fixed to the low average speed region of the board ^ The rubber suspension is used to assist the cantilever, which can be installed in the The cantilever above. Resonant panel loudspeakers may include a sound radiator of a distributed mode as defined in the patent application W097 / 09S42. νμ The other target of the Γ is a decorative rectifier plate, such as for a car or a speaker such as X, ′-in which the aforementioned speaker is contained. Another concept of the present invention is applied to a vehicle such as a lifter or a rectifier. The other concept of Zao / Zhongjiao is a manufacturing method of resonant plate-type sound.

Description of the invention (6) '' ------ Figures 4 to 7 are illustrations of the aforementioned general type resonance plate type. ^ A resonance plate having a larger plate 24-part! For example, the decorative panel D of a Kobe-type automobile or such a vehicle. In this example, the speaker shoveled a wide groove; the slot 25 is defined by a rectangle in the larger plate 24; To bridge the gap around the low-average I-producing plate i 'domain Λ slot. Each side of the plate 1 is provided with a suspension, ° vibration: The Bao Yi 4 series can be suspended as described or in the desired manner. As shown in FIG. 6, the binding u passes only partially through the board 1. As shown in the figure, the slot 25 is passed through the sandwich 2 of the upper epidermis 3, and the following table [is retained to cover the slot. In a manner as shown in FIG. 7, the slot 25 can penetrate the plate 1 completely. Regarding the application of the present invention to automobile decorative panels and similar decorative structures, the slot system can be formed in the early stage of manufacture, such as cutting with laser or water jet, and the slot system only needs to be wide enough to make the vibration component have a stable gap. Degree. In practice, a width of 1 mm or 2 mm is usually sufficient. The width of the suspension component depends on the toughness and linear stiffness of the plate and the acceleration force in the area of the effective length of the cantilever needed for the entire assembly to continue. A value of 4 to 25 _ is proven to be the effective width of the cantilever. Another point is to consider its durability under lateral acceleration. A fairly narrow 2 slot width makes the board more securely grounded than the surface configuration bonded to the flexible suspension assembly. In the latter, the suspension is able to withstand damage during disassembly. / / Sound configuration%, radiation separation between the front and rear panel surfaces is required, larger panels can be used as buffer panels and usually by local structures, such as door frames or some frames

For use in a building, the structural panel is enhanced by the design of the house or building. Between the front and rear plates, the leakage of sound through the slit is negligible. This slow leak is good for stray noise isolation from back to front of the board, which is important in some applications. Regarding automobile decorative panels, in the later stage of manufacturing, it is considered to stack a light-weight soft decorative cloth on a layer of soft open polyurethane sponge. The structure can be applied over the slot without detracting from the operating principle. The slot is not visible to the user. Further subtle improvements in sound isolation are obtained from the limited acoustic resistance of the slots in the sponge and cloth cover. The industrial advantages as shown in the configuration are as follows: 1. The suspension device can be the same material as the board, so the cost is low; 2. The suspension device can be the same or slightly thicker than the board; 3. Some of the suspension The position can suspend the plate on the relatively fixed part of the vibration oscillator, and / or suspend the plate on a frame or other support; and 4. The simple cantilever / beam calculation can immediately provide the required compliance value.
