M352209 八、新型說明： 【新型所屬之技術領域】 本創作係有關一種喇u八之散熱裝置，尤指一種針對薄型 小喇叭之有限空間内，以一板型金屬體套設在U型導磁軛周 圍，以增進散熱效率之構成。 【先前技術】 按，一般如筆記型電腦（NB)、液晶螢幕（LCD)、個人 數位助理器（PDA)等3C電子裝置，其除了運作效能之提升 外，更逐漸往薄型化之方向設計，以及多媒體功能之發展， 因此諸如此類之3C電子裝置會搭配一個適合之小型剩π八，作 為聲音輸出介面。 次按，喇π八是一種把電子訊號轉換成聲音訊號的電聲器 件，主要是在音圈通電後與磁體之間會產生互斥，形成類似 活塞式作用，因而順勢推動磁體前方的振膜，將振膜前方的 聲波向四周輻射出去。然而，音圈在與磁體作動時容易導致 高溫，此高溫的問題亦已成為無可避免的缺失。 再按，由於現今薄型消費性產品體積愈做愈小，因此產 品内部的電子或塑膠零件與喇队單體位置相當靠近。所以， 當喇"八單體的音圈通電後，音圈與磁體間的活塞作用會產生 高溫，高溫除了影響音質的表現，持續過高的溫度，也可能 影響產品内部鄰近零件的運作效率，更有甚者，音圈還可能 因為持續高溫而燒毁，或造成該產品本身的損壞，甚至對消 費者的使用造成危險。 M352209 承上，喇D八單體的散熱不良，嚴重者除了可能導致音圈 燒毁外，高溫也會影響既有的音質表現。因此，傳統上有不 少解決音圈散熱問題的習知技術，主要有氣體的對流、單體 喇叭結構的改良、以及改善金屬散熱材質等方式。 如我國專利00305509,將喇》八的防塵蓋材質改成金屬材 質，並直接置於音圈的開口處，直接將音圈的熱透過金屬的 防塵蓋，將熱氣排出。 又，如我國專利00431741，則是透過制D八機構的改良， 於喇《八作動時，可以將喇β八外部的冷空氣帶入音圈與磁體的 間隙中，順勢把間隙中的熱氣帶出，避免音圈過熱。 又，如我國專利00453601内容，直接於音圈上設置環 型散熱片，並將磁鐵包覆住，以導出音圈與磁體的高溫。 又，如我國專利M249394C大陸地區的專利ZL02288716.4) 内容，該發明直接在音圈與磁體後端的金屬體上，黏著一板 片型之散熱片，將11 刺11 八作動的熱氣排出，以避免音圈過熱。 又，如大陸地區的專利ZL200620014749. 2，該發明主要 在華司（喇《八單體的上導磁片）設置一環型散熱片，該散熱片 呈鋸齒狀結構，可加快音圈熱能的排出。 又，如大陸地區的專利ZL200720000787. 7，該發明為， 設置一凹型散熱裝置，將磁鐵下的導磁軛鐵（U鐵），安置於 該凹型散熱裝置中，再透過散熱膏將兩者緊密結合，因此， 當單體的熱傳導至導磁輛鐵時，可以直接透過外部的凹型散 熱裝置，將熱能快速的排出。 又，如大陸地區的專利ZL99217826. 6，則是在導磁輛鐵 (Τ鐵）的周圍開設數個散熱孔，並於導磁柱上同樣開立圓 M352209 孔，同時於導磁輛鐵的底部，採用鰭片設計以加強散熱的效 率。 又，如大陸地區的專利ZL200520053787.4,則是將原本 導磁輛鐵（U鐵）的導磁與固定磁體功能分離，並透過導磁 軛鐵材質的改變，採用輕質的材質取代傳統的鐵質材質，除 了可以減輕單體重量之外，也可以達到散熱的目的，同時， 在導磁輛鐵外設有散熱片，以加強散熱效率。 又，如大陸地區的專利ZL200420083784. 0，該發明將内 磁式單體結構進行改良，除了強化了單體的導熱效率外，也 提升了低音的音質。該發明主要是透過對内磁式單體結構改 良，於導磁軛鐵（U鐵）外設有一鋸齒狀散熱器，可將音圈 的熱能透過導磁軛鐵，傳導至該散熱器。同時，此散熱器帶 有圓周方向的開槽，透過喇队支架上的開孔，延伸振膜後面 的氣腔空間，可以在不額用使用音箱的情況下，進一步降低 最低共振頻率點F0，達到提升低音音質的目的。 惟查，上揭先前技術中（Prior Art)，針對音圈散熱問 題所揭露（Disclosure)之方法或結構，有的散熱效率仍未 臻理想，有的則是體積太大，不適用於薄型喇°八之極有限空 間，故仍有改善空間。 是以，針對上述問題點，提出有效的解決方案，為本創 作之主要課題。 【新型内容】 緣是，本創作之主要目的，係在提供一種薄型小喇'1 八散 熱裝置，其具有將導磁輊所產生熱能，以一板形金屬體迅速 且均勻地導出，以達最佳散熱效率。 M352209 本創作之又一目的，則在提供一種薄型小喇°八散熱裝 置，其作為散熱介質之板形金屬體，係套設在該LJ型導磁軛 之周圍，不僅裝設便捷。且不會佔用到薄型小喇'1八的有限内 部空間，具有實用性及3C產業的利用性。 為達上述目的，本創作所採用之技術手段包含： 一小型喇叭單體，至少具備上方之振動膜件及下方之U 型導磁軛； 一上蓋，具備一通孔供該小型喇叭單體之振動膜件將聲 音送出； 一下蓋，係配合該上蓋所設成並能將該小型喇叭單體包 覆其内；以及 一板形金屬體，其形狀可配合該上、下蓋内部空間所設 成，且其相對於該U型導磁軛設有一鏤空孔，且該鏤空孔内 徑，設有一可套設在該U型導磁輛周圍之環形固定框，據以 使該板形金屬體與該U型導磁輊結合，俾將U型導磁輛所產 生的熱能均勻導出者。 依據本創作前揭特徵，該板形金屬體可包括為銅、鋁、 鐵.....等任何具有散熱性的金屬材料所構成。 進一步，該板形金屬體亦可呈現波浪狀溝槽或熱散鰭片 之型態，藉以增進散熱面積及效率。 再者，該板形金屬體亦可配合上、下蓋之空間設有數個 柩孔，據以增進組裝之穩固性。 藉助上揭技術手段，本創作具有迅速地解決薄型小喇°八 的散熱問題，不僅增加產品之可靠度及使用壽命，並具提昇 音響品質之功效。 M352209 【實施方式】 首先，請參閱第-〜三圖所示，本創作之一較佳實施例 包含有： 一小型喇八單體（ίο)’其至少具備上方之振動膜件（ιι) 及下方之u型導磁軛（12);當然，如第四圖所示，其内部尚 包括音圈（14)及磁鐵（13)等元件，惟此皆非本創作^專 利標的，容不贅述。 上蓋（2 0)，具備一通孔（21)供該小型制„八單體门〇) • 之振動膜件（11)將聲音送出； 一下蓋（30)，係配合該上蓋（2〇)所設成，並將該小 型喇叭單體（10)包覆其内。其一較佳實施例，但不限定於 此，即其相對於該u型導磁軛（12)具有一通孔（31)，供該 u型導磁輛（12)底緣顯露。再者，另—較佳實施例係該通 孔（31)具有環壁（32)。此外，該下蓋（3〇)對應於該上蓋 (20)之上結合孔（22)，可設有與之配合之下結合孔（33)， 使上、下盍（20)、（30)能穩固結合。 • 一板形金屬體（40)，其形狀可配合該上、下蓋（20)、 (30)内部空間所設成，且其相對於該口型導磁軛（12)設 ' 有—鏤空孔（41)，且該鏤空孔（41)内徑，設有-可套設在 • 該1_]型導雜（12)周圍之環形固定框（42)，據以使該板形 金屬體（40)與該u型導购（12)結合，俾將⑽導磁輕 (12)所產生的熱能均勻且快速導出。 本創作之主要特徵’即在於該板形金屬體（4〇) 巧妙結 合在該u型導磁_ (12)的周圍，藉以增加散熱效率。且其 組裝非承便捷，又不會佔用到薄形小剩口八的有限内部空間， M352209 堪稱具實用性。 而’板形金屬體包括由具有散熱性之銅、紹..... 材料所成型。且，如果需要可於其中-部分表面 吾又有數個枢孔（43)。 第五圖所不’係第二圖中4-4及5-5斷面剖示圖， 八顯不βυ型導磁輛（12)内部之磁鐵⑴）及音圈（⑷M352209 VIII. New description: [New technical field] This creation is related to a kind of heat dissipation device, especially a kind of thin metal speaker in a limited space, with a plate metal body set in U-shaped magnetic Around the yoke to enhance the efficiency of heat dissipation. [Prior Art] Press, generally, such as notebook computer (NB), liquid crystal display (LCD), personal digital assistant (PDA) and other 3C electronic devices, in addition to the improvement of operational efficiency, it is gradually designed in the direction of thinning, As well as the development of multimedia functions, such 3C electronic devices will be paired with a suitable small π8 as a sound output interface. Sub-press, π 八 is an electro-acoustic device that converts an electronic signal into an acoustic signal, mainly because the voice coil is energized and mutually repulsive with the magnet, forming a piston-like action, thereby pushing the diaphragm in front of the magnet. , the sound waves in front of the diaphragm are radiated out. However, the voice coil is prone to high temperatures when it is operated with the magnet, and the problem of this high temperature has become an inevitable deficiency. Press again, as today's thin consumer products are getting smaller and smaller, so the electronic or plastic parts inside the product are quite close to the lama's monomer position. Therefore, when the voice coil of the eight-cell is energized, the piston between the voice coil and the magnet will generate high temperature. In addition to affecting the performance of the sound quality, the high temperature may continue to affect the operation efficiency of adjacent parts inside the product. What's more, the voice coil may also burn out due to continuous high temperature, or cause damage to the product itself, and even cause danger to consumers. M352209 bearing, the heat dissipation of the La D eight single unit, in addition to the serious cause of the voice coil burned, the high temperature will also affect the existing sound quality performance. Therefore, conventionally, there are conventional techniques for solving the problem of heat dissipation of the voice coil, mainly including convection of a gas, improvement of a single horn structure, and improvement of a metal heat dissipation material. For example, in our patent 00305509, the material of the dust cover of the 》8 is changed into a metal material, and is directly placed at the opening of the voice coil, and the heat of the voice coil is directly transmitted through the dust cover of the metal to discharge the hot air. In addition, as in the case of China's patent 00431741, it is through the improvement of the D-eight mechanism. In the case of the eight movements, the cold air outside the beta-beta can be brought into the gap between the voice coil and the magnet, and the hot air in the gap is taken along the way. Out, to avoid overheating the voice coil. Moreover, as in the case of our patent 00453601, a ring-shaped heat sink is placed directly on the voice coil, and the magnet is covered to derive the high temperature of the voice coil and the magnet. In addition, as for the patent ZL02288716.4 of the Chinese patent M249394C, the invention directly adheres to the heat sink of a plate type on the metal body at the rear end of the voice coil and the magnet, and discharges the hot air of 11 thorns and 11 octaves to Avoid overheating the voice coil. Moreover, as for the patent ZL200620014749. 2 in the mainland, the invention mainly provides a ring-shaped heat sink in the Huashi (La's "eight-unit upper magnetic sheet", the heat sink has a sawtooth structure, which can accelerate the discharge of the voice coil heat energy. . Moreover, as in the case of the mainland patent ZL200720000787. 7, the invention provides a concave heat sink, and the magnetic yoke (U iron) under the magnet is placed in the concave heat sink, and then the heat is applied through the heat sink. The combination, therefore, when the heat of the monomer is conducted to the magnetically conductive vehicle, the heat can be quickly discharged through the external concave heat sink. In addition, as for the patent ZL99217826.6 in the mainland, several heat dissipation holes are provided around the magnetic iron (small iron), and the hole M352209 is also opened on the magnetic conductive column, and at the same time, the magnetic iron is guided. At the bottom, fins are used to enhance the efficiency of heat dissipation. In addition, the patent ZL200520053787.4 in the mainland is to separate the magnetic conduction of the original magnetic iron (U-iron) from the function of the fixed magnet, and to change the material of the magnetic yoke to replace the traditional one. In addition to reducing the weight of the unit, the iron material can also achieve the purpose of heat dissipation. At the same time, a heat sink is arranged outside the magnetic conductive iron to enhance the heat dissipation efficiency. Moreover, as for the patent ZL200420083784. 0 in the mainland, the invention improves the structure of the inner magnetic unit, and in addition to enhancing the heat conduction efficiency of the unit, the sound quality of the bass is also improved. The invention is mainly achieved by improving the structure of the inner magnetic type body, and has a sawtooth heat sink on the outer periphery of the magnetic yoke (U iron), and the thermal energy of the voice coil is transmitted to the heat sink through the magnetic yoke. At the same time, the radiator has a circumferential slot, and the air cavity space behind the diaphragm is extended through the opening on the racquet bracket, so that the lowest resonance frequency point F0 can be further reduced without using the speaker. Achieve the purpose of improving bass sound quality. However, in the previous technology (Prior Art), the method or structure for the disclosure of the voice coil heat dissipation problem, some of the heat dissipation efficiency is still not ideal, and some are too large, not suitable for thin type There is still limited space in the eight extremes, so there is still room for improvement. Therefore, in response to the above problems, an effective solution is proposed, which is the main subject of this creation. [New content] The main purpose of this creation is to provide a thin type of small '1 eight heat sink, which has the heat energy generated by the magnetic yoke, which is quickly and evenly exported by a plate-shaped metal body.
