Description of the Invention (The present invention relates to a sound device, and in particular to a sound device used for resonance bending wave types. A conventional resonance ridge wave device was described in WO 97 / 09842. This document describes a plate with a resonant bending pattern in the plate region. A converter can be set at a predetermined position to excite the resonant pattern to produce a loudspeaker or sound transmission state. This device is called Diffusion type loudspeaker. United States \ 347 335 describes a loudspeaker that bends along a beam. This installation =, bends and curved waves are excited at the -end of the beam and-non-reflection is reflected by other factors, ..., The anti-reflection is non-reflective, so the bending wave will end in the beam, will be discarded and will not be reflected back to the forward resonance type. According to the present invention, 0 # 1 ancient /, dagger /, you have this type of axis Multiple resonant bending patterns of the axis; 5 helmets 兪 _, m, and ...

Description of Invention (2气 1 轴 # The cut% is related to the fundamental frequency along the axis: Seeing the large frequency range, a large resonance pattern along the axis with a low fundamental frequency along one of the axes of a higher fundamental frequency will be followed. / For the purpose of h, the prior art document WO 97/09842 discloses The long and short axes, · 4 are related to each other and require similar basic frequencies.

It will be clear 'in order to achieve a high ratio of the width of the axis along the length axis: as far as possible, the visibility can be reduced by half, preferably less than three-thirds of the length. The non-m-line frequency of the wave pattern is excited. Preferably, these frequencies «the sound of the surroundings 2 == the pattern axis is orthogonal to the-plane, and is reduced in the plane of warp and non-pattern I. This can strengthen the alignment of the pattern axis plane of the warp pattern frequency. _ ^ ^ " As a result, the board can be particularly suitable for this type of tail-rate sound output that can be excited at the lower frequency. This output can compensate for a more even overall sound, with more sound on the ceiling or floor or phase.

Description of the invention (3) Prioritizing sound entry into a plane is the most favorable to enter a flat board rather than a shot, and increase the increase width. However, this assumption assumes that one-way performance is maintained and that the non-type axis along the non-type axis of the plate cannot be disturbed. The latter state requires a small space. In order to achieve a unidirectional behavior but a phase sequence shield repair of a plate with a sufficient width, a higher isotropic plate can be used. The plate can be rigid and bend about the non-type axis about the type axis. The bending rigidity of the pattern axis plate may be at least about 1.5 times that of the non-type axis, and more preferably at least about twice as hard. Because the resonant bending wave pattern along one axis causes a bend on a predetermined axis, the number of patterns along the non-type axis will be reduced if the plate is bent rigidly with respect to the pattern axis. One plate with isotropic bending rigidity can be used to have a wave or cell-like structure, so that each chamber or wave is concentrated on the plane of the plate along the non-type axis. In a specific example, a microphone may be provided with an excitation resonance bending wave pattern. In the better case, the microphone can be placed separately from the pattern space of the lower pattern in the pattern direction. To achieve this, the microphone may be placed at one of the preferred locations along the length of the element, such as substantially 4/9, 3/7 or 5/13 along the length of the pattern axis. These locations are similar to those shown in WO 97/09842, but in this document, these preferred locations have coordinates 値 in both directions. The microphone need not be placed on the pattern axis, but can be placed on it laterally. Multiple microphones are available. To provide multiple microphones in a preferred location, multiple microphones can be juxtaposed across the width of the board. This can increase the output. Alternatively, a unidirectional microphone may extend through the width of the plate in a preferred position. Even if it only causes bending along the pattern axis, this microphone can be more -6- This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) ~~ ----------- -Install -------- order --------- line (please read the precautions on the back before filling this page)

The curved microphone is used for two-dimensional elements that do not have a significant spatial range. For comparison: a single point transmission can also stimulate a plate in a poor position. For example, it is better to be close to the force. The F-curve hardness of the η axis at one end is' so that the other positions mentioned above can be weakened in the clamping plate in some ways, with «P to make the plate excited in a poorer position. The second step illustrates the present invention 'with reference to the accompanying drawings by way of specific examples-with Fig. 1 shows a sound device according to the present invention. Figure 2 shows the frequency output of the board shown in Figure i in three directions perpendicular to the plane of the board and along the pattern direction. Figure 3 shows the frequency output of the board shown in Figure 1 in three directions orthogonal to the plane of the board and along the non-type direction. Explanation of main component symbols: 1 component (or rectangular plate) 3 position (or line) 5 microphone 7 lead wire The rectangular plate 1 is shown as a flat plate extending substantially along the χ (length) and 7 (width) directions. The plate is isotropic in bending hardness and much narrower than its length. The plate also makes the X axis stiffer than the y axis. Therefore, the fundamental frequency is much smaller than the x-axis line ', that is, the pattern axis is much longer than the non-type y-axis. Therefore, there are far more resonant bending wave patterns along the X axis than the y axis. 479434 Xiu_111418 Patent Application Γ Commentary Ej ^ Revision sheet (October 90) 槪 A7 BJuly description (4a Multiple microphones 5 are spaced apart from each other and extend along the y direction across line 3 of the board width Line 3 is four-ninths of the length in the X direction from one end of the plate along the length of the plate.

In the description of Γ, the microphone position is restricted to a better position, but in a single board, the position is only affected by a preferred distance along the length of the board. In a conventional amplifier, there are a variety of traditional bending wave microphones. These microphones can be piezoelectric microphones. The dB pressure level of the sound produced on this board is a function of frequency. Figure 2 shows "on the axis, the sound Pressure level , That is, the vertical distance from the plane of the board, and from 45. and 60. 2 of the axis towards the X direction are offset in further directions. Figure 3 shows "on the axis, the sound pressure level, that is, the plane of the board The distance from the straight parent and the offset from 45 ° and 80 ° towards the y-axis are offset in the other direction. Therefore, Figure 3 shows the level of lateral sound pressure and Figure 2 shows the sound pressure level along the length of the board. The sound pressure level is measured at a distance of 1 m from the board. The board I is a corrugated polymer gauge sold under the trademark `` Correx ''. It is about 2.83 times the rigid axis and the rigid axis. Sound It is not very directional in the plane of the pattern axis (Figure 2). The frequency is eliminated to a very low angle, and the medium frequency is only slightly off the axis. The curve is a tradition obtained from, for example, WO 97/09842 The curve of the dispersion plate is similar. In contrast, in the plane of the non-type axis, the sound pressure level is strongly separated from the high-frequency axis and maintained at a flat level (Figure 3). The meter shows that the sound is sent sideways. . 'To increase the effect, the width of the board can be increased. When the board When it is large, the crest becomes a column and the lower frequency output decreases by 3 dB per octave. This point can compensate the drop output from these frequency ranges. However, the higher the rounding factor is, This paper scale applies the Zhongguanjia standard (5 ^ S) A4 specifications ⑽χ 297 public love 479434 Λ7 B7 6 V. Description of the invention (can be seen from the above relationship, so the board width is limited, so that the basic frequency is difficult to maintain fully in a single Direction behavior. ------------ ^ -------- Order --------- line (Please read the precautions on the back before filling this page) Ministry of Economic Affairs Printed by the Intellectual Property Bureau Staff Consumer Cooperatives -9-This paper size applies to China National Standard (CNS) A4 (210 X 297 mm)
