Description of the invention C. Scope of the invention The invention belongs to an acoustic device, and in particular to an acoustic device using a -distributed resonant bending wave mode on a board. Background Art The distributed speaker is described in WO 97 / _42. A bending wave converter forms an excited resonance mode distributed on Bangladesh, and thereby generates sound. Participants such as 胄 'this kind of yang can suffer from all · entity is-lower. The opposite effect of all vibration frequency modes of the bag body and this mode may occur when the disc body is placed in a shallow closed = body . If the outer edge of the disc is fixed on = ^, the center of the disc body can vibrate forward and forward; the frequency of this vibration is affected by the effect of the air cushion encapsulating the air and produces about A relative critical frequency of 1000 Hz. An example of another "solid" solid model might be the vibration = combination of its elastic suspension and disc vibration. The peaks in the frequency response of such individual frequencies caused by the all-solid mode are flawed. Therefore, in normal design, the distribution mode of the device must be in the frequency region outside this mode. In any case, i is not possible, so it is necessary to reduce the impact of this mode on the distributed mode audio device. According to the invention, there is provided an acoustic device comprising a disc body capable of supporting bending waves and a disc body having a total-solid resonance at a total-solid resonance frequency, -4 This paper is in accordance with Chinese National Standard (CNS) A4 Specifications (210 X 237 mm (please read the precautions on the back before filling out this page) -------- ^ --------- ^-488183 V. Description of the invention (· 2) The conversion service is used on the disc body to stimulate the distributed bending wave mode to make the disc body sound, and a mass is fixed to the disc body at a distance from the converter to control all-substance resonance. It is best to use a coupling body to mass Fixed to the disc, the coupling body is at a relatively high frequency day: the mass can be adjacent to the mass from the disc body. The coupler can be a directional coupling, such as a spring or a compliant metal foil at a frequency More than all _ When the resonance frequency of the entity is higher, the resonance bending wave is removed from the disc body. Compliance: The compliance can also be obtained by the elastic transformation or addition of the core and the skin of the disc body. The coupler can fix the mass to the disc body. When the resonance frequency of the weight on the coupler is high, the mass can be completely decoupled from the disc body. The compliance of the compliant coupler is optional so that the resonance frequency of the mass on the compliant coupler can meet the required Acoustic results. The resonance frequency of the coupler with mass and compliance can be above the frequency of the solid mode. When the basic frequency of the life curve mode is in the case of isometry, we get f0 = 7Γ / Α λ / (B / ζ〇, Here A is the area of the disk body, B is the bending strength, and 〆 is the unit density of kilograms per square kilometer. The distribution mode speaker of the prior art has a relatively low basic frequency arrangement, which makes the disk body within the operating frequency range. It has a sufficient distribution pattern. In any case, it is possible that the disk body is harder than the better one in some applications, that is, the disk body may need to be “excessively hard”, and there is a bending hardness that should be selected to reduce it when it is more normal. The fundamental frequency is high. In this case, the reduction of the effect of plus-quality on the all-entity mode may be particularly useful. -5- This paper size applies the Chinese National Standard (CNS) A4 specification (21〇X 297) Meal) Γ% First read the phonetic on the back?

Description of the invention (.3) The mass fixed to the disc body can be directly proportional to the mass of the disc body. That is, about 0% or 20% of effective exercise quality. And 2% or 300% of the mass. Light-weight multimedia speakers can have, for example, an effective sports disk with a mass of 8 grams. For this application, a mass between 丨 grams and 10 grams must be fixed on the disk. In any case, the mass depends on several parameters, such as the weight of the system, the associated spring constant, and the actual mechanical connection of the new body. The mouth quality f is preferably fixed near the center of the disc. This choice has nothing to do with the mode drive, but it is considered that the mass should be placed close to the center of mass of the disk, so that the added mass can control the all-solid mode. The best position is the coupling to the low-resonance mode compared to the full_solid mode. This position can be found by systematic experiments or computer analysis of the mechanical connection of the disk. After the closure body can be provided to the disc body, the closure body can have an open hole or a full closure type, and in particular, the closure body can be a conventional shallow closure body whose action is like a buffer. The invention relates to a method for manufacturing an acoustic device, and its continuous steps are to provide: a disc body capable of supporting bending waves, and a converter on the disc body; using the converter to excite the distributed bending wave mode on the disc body; The sound of the disc body determines the frequency response of the disc body, finds a full-body solid resonance frequency of the all-solid resonance frequency, and adds a mass to the disc body at a special place to control the all-body resonance. The panel < frequency response can be obtained by using system analysis or mathematical calculations. Once a sound device is completed, you can simply use a similar disk and a -6-This paper size is applicable to China National Standard (CNS) A4 specifications (210 x 297).

The optimal disk thickness compared to the same material is 035 ton-meter, 333 mm long, 2M mm wide, and frequency 7 · 8 kHz. The disc body according to the invention is 78 Hz higher. The plate body 11 is supported by a 4mm thick double-face-transformation * / S-bead T17 glued to the outer periphery of the plate 11 and elastically supported on the frame 13 to provide relatively compliant support.

Description of invention r5 ). As shown in Figure 717 above, two exciters 19 are installed in the f-set / excitation hybrid as described in WO 97/09842. A 25 ohm cable is connected to a 9 ohm DC resistor in series. Parallel connection is also possible. Figure 3 does not show the sound pressure and volume of the disk as a function of frequency when measured at a distance from the disk. & The first peak value between M0 Hz and 1000 Hz should be the result of all the body modes caused by the disk 11 with air and air cushion under the envelope 15.舲 Enter, & a This complete Shao-entity model can be overcome by adaptors that encapsulate the air in the body. > Shell 1, 21, that is, a very small mass is added to the plate along the edge 8 8 亳 meters and 63 Mao meters away from the edge with the same amount of double-sided adhesion as the general adhesive tape-thin Compliant with plastic body 23 and fixed together. The mass is 31 grams. It can be seen in Figure 4 that the 'spikes' can be completely controlled at higher frequencies without significant changes. The selected amount of f 2 1 used to control its output can reduce its sensitivity and the resonance frequency completely at all-solid mode frequencies. When the disk body becomes denser, that is, at a higher frequency, the mass 21 changes from the disk body 11 to uncoupling and increases. The position of quality is obviously extremely important for fine-tuning control. Adjusting the position 'mass and installing the mass to the disc body can obtain control of the system response, and obtain a better acoustic response such as a frequency function.
