1246349 五、發明說明（1) 【發明所屬之技術領域】 本案係關於一種揚聲板結構，尤指一種掛晝式平面 -揚聲器之揚聲板結構。本發明亦關於具此一揚聲板之掛 畫式平面揚聲器。 【先前技術】 傳統的揚聲器主要是利用一圓柱狀電磁動力式激震 器來推動一圓錐形振膜以達到揚聲的目的，雖然傳統揚 聲器的應用範圍不小，但因其需靠一音箱來幫助揚聲， 所以會有體積大、笨重、具揚聲死角等缺點。近年因科 技進步，不少附有音效的電子與通訊產品如手提電腦、 手機、個人數位助理（P D A )等正朝影音合一、輕與薄的方 向發展，因此，平面揚聲器（panel-form loudspeaker) 有逐漸取代傳統揚聲器的趨勢。 除了應用於電子與通訊產品外，近年來，平面揚聲 器亦開始應用於音響設備中。以家用音響為例，除光碟 機以夕卜，音箱所佔的體積實在太大了 ，在室内佈置上相 當費心，例如除需考量擺放於收聽效果佳之位置外，亦 不可使外觀單調的音箱影響室内裝潢之整體評價。為了 解決此問題，近年來，技藝中發展出一種掛晝式平面揚 聲器，其係將平面揚聲器之原理應用到掛晝上，以畫板 作為揚聲板，利用激震器振動晝板而達到揚聲的目的。 晝板上可預先繪上世界名畫，或者可視使用者之需要在 畫板上貼上所欲的圖畫，例如山水畫、風景晝、明星照1246349 V. Description of the invention (1) [Technical field to which the invention belongs] This case relates to a speaker panel structure, especially a speaker panel structure of a day-type flat-speaker. The present invention also relates to a picture-type flat speaker having such a speaker board. [Previous technology] Traditional speakers mainly use a cylindrical electromagnetic power shaker to push a cone-shaped diaphragm to achieve the purpose of loudspeaker. Although the application scope of traditional speakers is not small, but it needs a speaker to help Loudspeaking, so there are shortcomings such as bulky, bulky, and dead angles. In recent years, due to technological progress, many electronic and communication products with sound effects, such as laptop computers, mobile phones, and personal digital assistants (PDAs), are developing in the direction of audio-visual integration, lightness and thinness. Therefore, panel-form loudspeakers ) There is a tendency to gradually replace traditional speakers. In addition to electronics and communication products, flat speakers have also been used in audio equipment in recent years. Taking home audio as an example, in addition to the optical disc player, the volume occupied by the speakers is too large, and the interior layout is very troublesome. For example, in addition to considering the placement in a location with good listening results, you cannot make the appearance of a monotonous speaker. Influence the overall evaluation of interior decoration. In order to solve this problem, in recent years, a hanging-type flat speaker has been developed in the art, which applies the principle of the flat speaker to the hanging day, using a drawing board as a speaker board, and using a shaker to vibrate the day-board to achieve a speaker. purpose. The world famous paintings can be painted in advance on the day board, or the desired pictures can be pasted on the board according to the needs of the user, such as landscape painting, landscape day, star photos

Description of the Invention (2) Films or personal photos. In this way, it not only solves the problem of traditional large speakers, but also listens to light music when watching paintings, ensuring that people are refreshed. The first figures (a) and (b) respectively show a conventional hanging-type plane speaker's top view and sectional view. The hanging picture plane speaker 1 includes a frame 1 1, a speaker board 12, an electromagnetic power type shocker 13, and a flexible suspension element 1 4. The frame 11 is a rectangular hollow frame at the center, and the cross-section of each side of the frame 11 is L-shaped. The platform part in the L-shape is used to support the flexible suspension element 14. The flexible suspension element 14 is composed of a plurality of flexible rectangular strips. The flexible rectangular strips can be, for example, rubber gasket strips impregnated with viscose on the surface, foamed cotton strips or strip-shaped thin shells with curved sections. sheet. The speaker board 12, which is rectangular in appearance, is fixed in the frame 11 and carried on the flexible suspension element 14. As mentioned above, the board can be painted in advance, or a desired picture can be pasted as needed. The shock absorber 1 3 is attached below the speaker plate 12 and is mainly composed of a magnet group and a voice coil (not shown). The induced magnetic field generated after the voice coil is energized is moved up and down by the annular magnetic field between the magnet groups. , And use this movement to promote the speaker board 1 2 to achieve the purpose of speaker. Although the picture-type flat speaker has the advantages of small size and beautiful appearance, the current problem is that speaker boards are mostly made of materials such as metal, paper, wood, polymer or woven cloth. These materials have heavy weight or insufficient rigidity. Disadvantages, not as an ideal material for speaker panels. If the rigidity is not sufficient, the speaker plate will be distorted during low and medium frequency shocks. The rigidity of the speaker panel is mainly determined by the elastic modulus of the material (or Young's system

Description of the invention (3) number) multiplied by the moment of inertia (in 0 m e n t u m i n e r t i a, I). For a flat plate, the moment of inertia I 2 1/12 x length x (thickness) 3. And the weight of the flat plate is W 2 density x degree (length X width X thickness). Generally speaking, the method of improving the rigidity of the speaker board requires the selection of a material that is both rigid and thick. However, the increase in thickness means that the weight is increased at the same time, which makes the amplitude amount insufficient. Although this problem can be solved as long as a material with high rigidity and low density is found, in practice, no suitable material with both characteristics has come out. Therefore, how to obtain a rigid and lightweight speaker panel is a major issue facing the development of daylight flat speakers.

Description of the invention (6) A flexible suspension system is made of soft material and is adhered between the edge of the lower surface of the speaker board and the frame. This case can gain a deeper understanding through the following drawings and detailed description: [Embodiment] The second picture (a) and (b) show the top view of the picture-type flat speaker and its A- A sectional view. The picture-type flat speaker 2 of this case includes a frame 1 1, a speaker plate 2 2, an electromagnetic power type shocker 1 3, and flexibility.
懸吊元件1 4 ，其中框架1 1 、激震器1 3及柔性懸吊元件1 4 之構造及工作原理與第一圖同，在此不再贅述。 請配合看第二圖（b)及第三圖，本案之特徵在於揚聲 板2 2之結構，揚聲板2 2外觀上成矩形（長與寬分別為A及 B)，其主要由一片具長度a及寬度b之中央矩形子板220及 四片梯形子板2 2 1〜2 2 4所組成，其中個別梯形子板之上底 實質上相當於與梯形子板2 2 0相鄰之邊的邊長，且個別梯 形子板之下底實質上構成該矩形揚聲板之四邊。例如， 梯形子板222及224中每一者之上底及下底之長度分別為a 及A，而梯形子板221及223中每一者之上底及下底之長度 分別為b及B。The suspension element 14 is the same as the first figure in the structure and working principle of the frame 1 1, the shock exciter 13, and the flexible suspension element 14, and is not repeated here. Please look at the second picture (b) and the third picture, this case is characterized by the structure of the speaker plate 22, the speaker plate 22 is rectangular in appearance (length and width are A and B, respectively), which is mainly composed of a piece It is composed of a central rectangular sub-board 220 with a length a and a width b and four trapezoidal sub-boards 2 2 1 ~ 2 2 4. The upper and lower parts of individual trapezoidal sub-boards are substantially equivalent to those adjacent to the trapezoidal sub-board 2 2 0. The sides are long, and the bottom of the individual trapezoidal sub-boards substantially constitutes the four sides of the rectangular speaker board. For example, the lengths of the upper and lower bases of each of the trapezoidal daughter boards 222 and 224 are a and A, respectively, and the lengths of the upper and lower bottoms of each of the trapezoidal daughter boards 221 and 223 are b and B, respectively. .
矩形子板2 2 0之厚度（dl )較每一梯形子板22 1〜224 (d 2 )為厚。激震器1 3係黏貼於矩形子板2 2 0下方，藉此推 動揚聲板22，以達到揚聲的目的。其次，矩形子板2 2 0與 每一梯形子板2 2 1〜2 2 4相對於激震器1 3之側實質上呈一平The thickness (dl) of the rectangular sub-board 2 2 0 is thicker than each of the trapezoidal sub-boards 22 1 to 224 (d 2). The shock absorber 1 3 is attached to the bottom of the rectangular sub-plate 2 2 0 to push the speaker plate 22 to achieve the purpose of sound. Second, the rectangular sub-plate 2 2 0 and each trapezoidal sub-plate 2 2 1 ~ 2 2 4 are substantially flat with respect to the side of the shaker 1 3
第11頁 1246349 五、發明說明（7) 坦面，藉此可作為畫板而預先繪晝於其上，或者可視需 要貼上所欲的圖畫。 • 如前述，平面揚聲器之揚聲板結構之剛性與材料的 彈性模量X(厚度）:3成正比，而平板之重量與密度X厚度成 '正比，因此，當厚度增為2倍時，剛性即可增加8倍。利 用此特性，可設計出兼具高剛性與低重量之揚聲板。 在本案中，矩形子板2 2 0厚度d 1與每一梯形子板2 2 1〜 2 2 4厚度d 2之比例較佳為2以上，更佳為4以上。梯形子板 222及224中每一者之上底長度a及下底長度A之比例較佳 為1 / 4至2 / 3，更佳為1 / 3至1 / 2，而梯形.子板2 2 1及2 2 3中 每一者之上底長度b及下底長度B之比例較佳為1 / 4至 2/3，更佳為1/3至1/2。 為了獲致較大的剛性，矩形子板之彈性模量E為5 Μ P a 以上，更佳為1 GPa以上。再者，由於矩形子板220之厚 度d 1較傳統揚聲板厚度為大，故可提供整個揚聲板之大 部分岡J性（此時矩形子板2 2 0增加的重量有限）。由於每一 梯形子板221〜2 2 4之厚度d2較小且本案揚聲板22之重量主 要集中於梯形子板部分，故揚聲板2 2之總重量可大大地 降低。因此，本發明所提供之揚聲板可兼具高剛性與低 重量，同時解決習知技藝所面臨的問題。 再者，為了防止各梯形子板2 2 1〜2 2 4受激震時產生扭 曲現象，每一梯形子板平行兩底方向之彈性模量E 1須大 於垂直兩底方向之彈性模量E 2，且矩形子板2 2 0之彈性模 量E大於E 1。較佳地，E 1與E 2之比例為至少2。Page 11 1246349 V. Description of the invention (7) It can be used as a drawing board to draw the day in advance, or paste the desired picture if necessary. • As mentioned above, the rigidity of the loudspeaker structure of a flat speaker is directly proportional to the material's elastic modulus X (thickness): 3, and the weight of the flat plate is proportional to the thickness X thickness. Therefore, when the thickness is doubled, The rigidity can be increased by 8 times. With this feature, a speaker board with both high rigidity and low weight can be designed. In this case, the ratio of the thickness d 1 of the rectangular sub-board 2 2 0 to the thickness d 2 of each trapezoidal sub-board 2 2 1 to 2 2 4 is preferably 2 or more, and more preferably 4 or more. The ratio of the upper base length a and the lower base length A of each of the trapezoidal sub-plates 222 and 224 is preferably 1/4 to / 2, more preferably 1/3 to 1/2, and the trapezoidal sub-plate 2 The ratio of the upper base length b and the lower base length B of each of 2 1 and 2 2 3 is preferably 1/4 to 2/3, and more preferably 1/3 to 1/2. In order to obtain greater rigidity, the elastic modulus E of the rectangular daughter board is 5 MPa or more, and more preferably 1 GPa or more. Furthermore, since the thickness d 1 of the rectangular sub-board 220 is larger than that of the conventional speaker board, it can provide most of the J-shaped nature of the entire speaker board (at this time, the increased weight of the rectangular sub-board 220 is limited). Since the thickness d2 of each of the trapezoidal sub-boards 221 to 2 2 4 is small and the weight of the speaker panel 22 in this case is mainly concentrated on the trapezoidal sub-board part, the total weight of the speaker panel 22 can be greatly reduced. Therefore, the speaker board provided by the present invention can have both high rigidity and low weight, while solving the problems faced by conventional techniques. Furthermore, in order to prevent distortion of the trapezoidal daughter boards 2 2 1 ~ 2 2 4 when excited, the elastic modulus E 1 of each trapezoidal daughter board parallel to the two bottom directions must be greater than the elastic modulus E 2 of the vertical two bottom directions. And the elastic modulus E of the rectangular sub-plate 2 2 0 is greater than E 1. Preferably, the ratio of E 1 to E 2 is at least 2.
1246349 五、發明說明（8) 適用於本案揚聲板2 2中之矩形子板2 2 0可由木材、金 屬、紙、高分子或編織布製成。為了提供更佳的揚聲效 •果，矩形子板及每一梯形子板均可由選自木材、玻璃纖 維加勁之高分子樹脂材料、碳纖維加勁之高分子樹脂材 ‘料、克夫拉纖維加勁之高分子樹脂材料或硼纖維加勁之 局分子樹脂材料中之'一種材料製成’且其中該南分子樹 脂選自環氧樹脂、酚醛樹脂和多元酯樹脂。 綜上所述，本案僅藉由結構設計上之改良，即可獲 致具剛性大且重量輕之揚聲板，藉此有效地將揚聲板的 最佳振形及振動量激震出來，並可免除習知技藝中遇到 的缺點，實為一新穎、進步及實用之發明，爰依法提出 申請。 本案得由熟悉本技藝之人士任施匠思而為諸般修 飾，然皆不脫如附申請專利範圍所欲保護者。1246349 V. Description of the invention (8) The rectangular sub-board 2 2 0 suitable for the speaker board 2 2 in this case may be made of wood, metal, paper, polymer or woven cloth. In order to provide better sound effects and results, the rectangular daughterboard and each trapezoidal daughterboard can be selected from wood, glass fiber reinforced polymer resin materials, carbon fiber reinforced polymer resin materials, and Kevlar fibers. One of the molecular resin materials or boron fiber reinforced local molecular resin materials is made of one material, and the southern molecular resin is selected from the group consisting of epoxy resin, phenol resin, and polyester resin. To sum up, this case only through the structural design improvement, can obtain the speaker board with high rigidity and light weight, which can effectively excite the optimal shape and vibration amount of the speaker board, and Eliminating the shortcomings encountered in the know-how is a novel, progressive, and practical invention, and applies in accordance with the law. This case can be modified by anyone who is familiar with the art, but it is not as bad as the protection of the patent application scope attached.
