[Prior Art] Generally, a speaker is a device that converts an electrical signal into a sound signal. Micro-speakers are small speakers that are mainly used in small-sized audio equipment such as mobile phones, notebooks, mobile phones, notebooks, and other portable audio devices that have increased in demand in recent years. However, in recent years, electronic products including microspeakers, particularly mobile communication terminal devices such as mobile phones, have a structure for generating a vibration signal. Such a vibration signal is used to replace the incoming call signal or to confirm the input state in a touch screen that directly inputs information to the face. The microspeaker according to the present invention is provided with a speaker for generating a vibration signal, and also having a structure for generating a vibration signal. Micro speakers are called multi-function transmissions or multi-function electronic audio converters. A conventional microspeaker has a structure in which vibration is obtained by resonating a vibrator supported by a blade magazine. In such a conventional microspeaker, there is a 201129122 sound coil on a magnetic circuit having a side of a diaphragm which is also called a collecting plate, and when the sound signal is applied to the sound coil, the sound is turned "on" to the sound coil. Vibration is generated on the vibrator when a current is applied to the vibration signal. Fig. 1 shows an example of a conventional microspeaker. Referring to Fig. 1, a microspeaker 100 includes a frame 110, a sounding diaphragm 101, a voice coil 102, a permanent magnet 1 in which an N pole and an S pole are arranged in a downward direction, a flat plate 103, a yoke 1〇5, and a first suspension 106. The second suspension 1〇8, the upper cover 1〇7, and the weight member 109. The upper end portion of the voice coil 102 is fixed under the diaphragm 1〇1. The acoustic coil 102 is wound in such a manner that a current can flow in a direction perpendicular to the magnetic lines of force. The flat plate 103 is fixed to the upper surface of the permanent magnet 104, and the permanent magnet 1〇4 is fixed to the bottom surface of the yoke 105, and the yoke 105 is fixed to the first suspension 1〇6. The first suspension 106 is elastically supported by the frame 110. The yoke 1〇5, the permanent magnet 104, and the flat plate 103 form a magnetic circuit of the speaker. Next, the operation of the microspeaker 10A having the above configuration will be described. When a current suitable for audio is applied to the voice coil 102, an electromagnetic force is generated on the voice coil 102. Thus, the diaphragm 101 vibrates to output a sound of 9 frequencies. 103. The magnetic field of the voice coil 102 and the magnetic vehicle 105. At this time, the magnetic flux generated in the acoustic coil 1〇2 circuit interacts, and the diaphragm 101 vibrates, that is, the magnetic field lines emitted from the N-pole of the permanent magnet 104 sequentially pass through the flat plate to form an electromagnetic force on the ring 102 toward the permanent magnet 1〇4S.

圖是第3圖的俯視圖，第5圖是選取第2圖的重要部分而 表示的立體圖。 首先，參照第2圖，根據本發明的實施例的多功能微 型揚聲器包括：框架10;外周部固定在該框架1〇上的隔膜 20，固疋於該隔膜20下面的聲音線圈懸架4〇，其具 201129122 有彈性，且外周部結合在該框架10上；固定在該懸架40 上的磁耗（yoke)50 ;固定於該磁輛50底部51的永久磁鐵 60 ;以及固定於該永久磁鐵60上面的平板(plate)70，其中 該懸架40由與該框架10結合的主懸架部41和配置於該主 懸架部41上側的副懸架部42及連接該主懸架部41和該副 懸架部42的連接部43構成。 根據本發明的實施例的多功能微型揚聲器的主要特徵 在於該懸架40的結構。下面，首先對該懸架40的結構進 行說明。 如第3圖所示，該懸架40由具有彈性的材料構成。在 本實施例中，該懸架40由青銅等金屬板材製造而成。當然， 在其它實施例中，該懸架40可以由高分子彈性物質製造。 該懸架40包括主懸架部41和副懸架部42及連接部43。 該主懸架部41包括支承部411和安裝部412及支承架 413。 該支承部411是爲了將該懸架40固定於框架10上， 並且在懸架40進行振動時爲了支承其懸架40而設置的。 如第2圖所示，該支承部411作爲相當於主懸架部41邊緣 的部分而固定在框架10上。 該安裝部412是供該磁軛50的底部51安裝並固定的 部分。在本實施例中，該安裝部412形成爲圓形，並具有 比磁軛50底部51的直徑小的直徑。該磁軛50的底部51 黏接或焊接在該安裝面412上，或者可透過黏接膠片（未 圖示）而黏接在該安裝面412上。 201129122 »亥支承架413連接該支承部411和該安裝部412。該支 承架413的一端部與該支承部411連接，另一端部與該安 裝部412連接。. 如弟3圖所示’該支承架413在—定區域從該支承部 411延伸而與其支承部411隔開一定距離，然後朝向該安裝 部412而向内側折彎。在本實施例中，該支承架々η爲2 個連接及支承& 413與該支承部411 #支點4i3a彼此對 置而形成對稱。另外，連接該支承架413與該安裝部412的 支點413b也彼此對置而形成對稱。以對稱的方式配置的該 支承架413，使得懸架4〇以上下方向穩定地振動。 該副懸架部42包括延伸部421和結合部422。 該副懸架部42與該主懸架部41平行配置，並且透過 連接部43與該主縣牟邮4 ϊ、由& & 土 〜、木邛41連接。该連接部43從該主懸架 :丁 // 延伸。該連接部43向上側延伸該磁輛50的 上下冋度的量。在該連接部43的下

的寬度w與该磁輕50側壁部52的厚度相等。 201129122 在本實施例中，該磁軛50底部51安裝固定在該主懸 架部41的安裝部412上，該磁軛50的上端部固定在該結 合部422的下面。具體而言，如第5圖所示，在該磁輛50 的底部51結合有永久磁鐵60，該永久磁鐵60的上面結合 平板70的狀態下，該磁軛50的側壁部52的上端利用黏接 劑等而固定在該結合部422的下面。 因此，該磁軛50位於該主懸架部41和該副懸架部42 之間。更具體而言，該磁軛50的底部51與該主懸架部41 的安裝部412結合，該磁軛50的上端部與該結合部422的 下面結合。在懸架40進行振動時，磁軛50根據該主懸架 部41和副懸架部42而維持準確的位置。 另外，該懸架40的結構也可適用於線性振動器等致動 器（actuator)。 該永久磁鐵60以與磁輛50構成同心的方式固定於磁 軛50的内部底部51。爲了與磁軛50的形狀對應，該永久 磁鐵60形成爲圓盤形狀。該永久磁鐵60黏接在磁軛50的 底部51或透過黏接膠片而黏接在磁軛50的底部51。 該平板70固定於永久磁鐵60的上面。平板70由磁性 良好的材料構成，並且具有與永久磁鐵60幾乎相同的直 徑。該永久磁鐵60與該平板70被黏接或透過黏接膠片被 黏接在一起。 永久磁鐵60及平板70與磁軛50的上端部隔開距離而 固定。在與永久磁鐵60及平板70的外側面彼此對置的磁 軛50的上端部之間形成有空間，聲音線圈30的下部位於 201129122 該空間内。 永久磁鐵60、平板70及磁軛50構成揚聲器的磁性電 路。即，由永久磁鐵60產生的磁通形成經過平板70而進 入磁輛50的磁通路(path)。向該聲音線圈30施加適於振動 的電流（普通低頻的電流）時’根據由磁概5 0、永久磁鐵 60及平板70構成的磁性電路部（振動器）的上下運動而產 生振動信號。 該框架10通常由塑料構成。該框架10由形成側壁的 上部側壁框架12和下部側壁框架13及形成底面的底面框 架11構成。在該上部側壁框架12和下部側壁框架13之間 結合主懸架部41的支承部411。在該底面框架11上形成有 多個氣孔11a。該氣孔11a是爲了使在懸架40振動時產生 的框架10内部的空氣流動通向外部而設置的。如果在框架 10内部產生的空氣流動不通向外部，則會導致懸架40的諧 振頻率、衰減係數的變更而產生不完整的振動，因此需要 透過氣孔11a來使框架10内部的空氣通風。 在框架10的上部結合有隔膜20的外周部。另外，在 該隔膜20的上面結合有上部蓋90的外周部。 在本實施例中，框架10在整體上形成爲圓筒形狀，並 且爲了從外部供電，具有供電端子連接部（未圖示），在供 電端子連接部上結合有用於向聲音線圈30供電的引線（未 圖示）。 當然，在其它實施例的情况下，框架10的橫剖面外形 可以是四邊形狀、橢圓形狀或者軌道形狀。在各情况下， 11 201129122 内部部件也可根據其外部形狀而適當變形。 ，該隔膜20的外周部固定在框架1〇的上部。 爲圓形，通常由高分子化合物構成。隔膜2〇進行上下据 而產生人們能夠聽到的聲壓。 在本實施财，該_ 2G以結合聲音㈣3

與主懸架部41的安裝部412的下面結合。該配重部件8〇 12 201129122 黏接在該懸架40上。 該配重部件80與該懸架40共同構成產生振動信號的 振動器。透過調整構成振動器的懸架40之彈性程度和配重 部件80的重量而能夠調整諧振頻率和振動力。 下面，對具有上述結構的根據本發明的多功能微型揚 聲器的作用及效果進行詳細說明。 結合有永久磁鐵60和平板70的磁軛50被夾在主懸架 部41和副懸架部42之間而進行結合。該磁軛50的底部51 固定於主懸架部41的安裝部412,磁軛52的上端部固定於 副懸架部42的結合部422。 因此，維持磁軛50的下端部和上端部均固定於形成爲 2段結構的懸架40的狀態，因此即使懸架40持續振動，也 能夠穩定地維持磁輛5 0的位置。 另外，將懸架40形成爲主懸架部41和副懸架部42的 兩段結構而分別支承該磁軛50的下端部和上端部，因此提 供在懸架40振動時，分散磁軛50、永久磁鐵60及平板70 的重量的效果。以往，在多功能微型揚聲器100中，磁軛 105、永久磁鐵104、平板103均配置在該第一懸架106的 上侧。因此，該第一懸架106需要在該磁軛105的下側支 承該磁輛50、永久磁鐵103、平板103的重量，因此導致 施加到第一懸架106的重量加重，從而在第一懸架106持 續振動時容易發生破損。而在本發明的多功能微型揚聲器 200中，在下側由主懸架部41支承該磁軛50、永久磁鐵60、 平板70的重量，在上側由副懸架部42進行支承，因此提 13 201129122 供分散重量的效果。 另外，將磁軛50定位於主懸架部41的安裝部412時， 只要使磁軛50的上端部固定於結合部422即可，因此容易 進行磁輛5 0的定位。並且，能夠將磁輛5 0的位置始終保 持在相同的位置，從而減少產品特性偏差，並且容易進行 磁軛50的結合而縮短製造時間。 另外，根據本發明的多功能微型揚聲器，與習知使用 第一懸架106和第二懸架108的情况不同，僅使用一個懸 架40，因此減少多功能微型揚聲器的構成部件數而降低構 成部件中所需的費用，並且將製造程簡單化而減少製造時 間。 以上，詳細說明了本發明的較佳實施例，但是本發明 不限於上述實施例，在不脫離本發明範疇的範圍内可進行 多種變形。因此，本發明真正的技術保護範圍應該由所附 申請專利範圍的技術思想而定義。例如，主懸架部的支承 架之數量可變形爲各種各樣，副懸架部之數量也可變形爲 各種各樣。另外，在本發明實施例中使用了配重部件，但 是也可以採用磁鐵來代替該配重部件。 【圖式簡單說明】 第1圖是習知多功能微型揚聲器的概略性剖面圖。 第2圖是根據本發明實施例中多功能微型揚聲器的剖 面圖。 第3圖是選取第2圖重要部分而表示的立體圖。 14 201129122

circuit portion (vibrator). The conventional micro-lifting problem of the above structure. As shown in Fig. 1, the permanent magnet 104 and the flat plate 1〇3 are combined with the upper and lower layers to form a magnetic circuit. The bottom surface of the hybrid 1G5 is The first part of the suspension is the center of the suspension. The first suspension is vibrated in the upper and lower directions in order to generate vibration. However, at this time, only the bottom surface of the magnetic vehicle (10) is set to be vibrated at the H1G6, so When the suspension 脳 is vibrated, it is possible that the yoke β 105 is separated, and when the first suspension 106 is twisted due to an external impact or the like, the miscellaneous (10), the permanent magnet 104, and the flat plate 103 are vibrated in an inclined state. If the yoke 1〇5, the permanent magnets 1〇4, and the flat plate 103 vibrate in an inclined state, the sound level of the multifunctional microspeaker is lowered. Further, the bottom surface of the yoke 1〇5 is bonded by an adhesive or the like. The The central portion of a suspension 1 ' 6 'However, it is difficult to accurately position the magnetic vehicle in the central portion of the first suspension 1 , and sometimes it becomes an important cause of variation in product characteristics. Moreover, in order to control the vibration force, in addition to the use of In addition to the suspension 1〇6, the second suspension 108 and the weight member 109 are additionally used, so that the number of components is increased, and the productivity is lowered due to the complicated internal structure. The present invention is to solve the above problems. Rather, the object of the present invention is to provide a multifunctional microspeaker that stably maintains the position of the magnetic body coupled to the suspension when the suspension is vibrating 5 201129122, and combines the magnetic vehicle at a predetermined position of the suspension while enhancing the combination thereof. And the assembly process is simplified and the component cost is reduced. In order to achieve the above object, the multifunctional microspeaker of the present invention comprises: a frame; a diaphragm having a peripheral portion fixed to the frame; a sound coil fixed under the diaphragm (4); a suspension , which has elasticity, and the outer peripheral portion is coupled to the frame to fix the magnetic vehicle (yGke) m on the suspension a permanent magnet of the bottom of the magnetic vehicle; and a flat plate fixed to the upper surface of the permanent magnet, wherein the suspension is connected to the main suspension portion coupled to the frame, and a sub-suspension portion disposed on the upper side of the main suspension = and connected to the main Preferably, the suspension portion is connected to the connection portion of the sub-suspension portion. Preferably, the main suspension portion is disposed in parallel with the 悬j suspension portion, and the yoke is located between the main suspension portion and the sub-suspension portion.

The clothing further preferably, the auxiliary suspension portion includes: from the The upper portion of the connecting portion and the extension portion of the extending portion and the end portion of the extending portion are preferably combined with the central portion of the main suspension portion, the yoke of the yoke The upper end portion is combined with the lower surface of the joint portion. Preferably, a weight member is coupled to the lower surface of the main suspension portion. According to the multi-functional microspeaker of the present invention, since the two-stage structure of the suspension portion and the (four) frame portion are (4) reduced between the main suspension 6 201129122 portion and the sub-suspension portion, the suspension is stably maintained during vibration. The position of the yoke. Further, since the yoke is disposed between the main suspension portion and the sub-suspension portion, the position of the magnetic beam coupled to the suspension can be easily selected. The bottom surface of the magnetic yoke is fixed to the main suspension portion, and the upper end portion of the yoke is fixed to the sub-suspension portion, so that a strong bonding force can be maintained between the yoke and the suspension. Further, unlike the case where the first suspension and the second suspension are used in the past, the present invention employs only one suspension, so that the assembly process is simplified and the component cost is reduced, thereby providing an effect of improving production efficiency and reducing manufacturing cost.

The έ 结合 joint portion 422 is divided into a predetermined space by the 磁 〇 〇 、 、 、 、 、 、 、 、 、 、 、 421 421 421 421 421 421 421 421 421 421 421 421 421 421 421 421 421 422 422 422 422 422 422 422 422 422 422 422 422 422 422 422 The edge support jaws 411 have the same curvature as the skewed sheep. The width w of the joint portion 422 is equal to the thickness of the side wall portion 52 of the magnetic light 50. In the present embodiment, the bottom portion 51 of the yoke 50 is attached and fixed to the mounting portion 412 of the main suspension portion 41, and the upper end portion of the yoke 50 is fixed to the lower surface of the joint portion 422. Specifically, as shown in Fig. 5, a permanent magnet 60 is coupled to the bottom 51 of the magnetic vehicle 50, and the upper end of the side wall portion 52 of the yoke 50 is viscous in a state where the upper surface of the permanent magnet 60 is coupled to the flat plate 70. An adhesive or the like is fixed under the joint portion 422. Therefore, the yoke 50 is located between the main suspension portion 41 and the sub-suspension portion 42. More specifically, the bottom portion 51 of the yoke 50 is coupled to the mounting portion 412 of the main suspension portion 41, and the upper end portion of the yoke 50 is coupled to the lower surface of the joint portion 422. When the suspension 40 vibrates, the yoke 50 maintains an accurate position in accordance with the main suspension portion 41 and the sub-suspension portion 42. Further, the structure of the suspension 40 can also be applied to an actuator such as a linear vibrator. The permanent magnet 60 is fixed to the inner bottom portion 51 of the yoke 50 so as to be concentric with the magnetic vehicle 50. The permanent magnet 60 is formed in a disk shape in order to correspond to the shape of the yoke 50. The permanent magnet 60 is bonded to the bottom 51 of the yoke 50 or bonded to the bottom 51 of the yoke 50 through the adhesive film. The flat plate 70 is fixed to the upper surface of the permanent magnet 60. The flat plate 70 is made of a magnetically good material and has almost the same diameter as the permanent magnet 60. The permanent magnet 60 is bonded to the flat plate 70 or bonded through the adhesive film. The permanent magnet 60 and the flat plate 70 are fixed at a distance from the upper end portion of the yoke 50. A space is formed between the upper end portions of the yokes 50 opposed to the outer surfaces of the permanent magnets 60 and the flat plates 70, and the lower portion of the voice coil 30 is located in the space of 201129122. The permanent magnet 60, the flat plate 70, and the yoke 50 constitute a magnetic circuit of the speaker. That is, the magnetic flux generated by the permanent magnet 60 forms a magnetic path that enters the magnetic vehicle 50 through the flat plate 70. When a current suitable for vibration (current of a normal low frequency) is applied to the voice coil 30, a vibration signal is generated by the vertical movement of the magnetic circuit portion (vibrator) composed of the magnetic field 50, the permanent magnet 60, and the flat plate 70. The frame 10 is typically constructed of plastic. The frame 10 is composed of an upper side wall frame 12 and a lower side wall frame 13 which form side walls, and a bottom frame 11 which forms a bottom surface. A support portion 411 of the main suspension portion 41 is coupled between the upper side wall frame 12 and the lower side wall frame 13. A plurality of air holes 11a are formed in the bottom frame 11. The air hole 11a is provided to open the air flow inside the frame 10 which is generated when the suspension 40 vibrates to the outside. If the air generated inside the frame 10 does not flow to the outside, the resonance frequency and the attenuation coefficient of the suspension 40 are changed to cause incomplete vibration. Therefore, it is necessary to ventilate the air inside the frame 10 through the air holes 11a. The outer peripheral portion of the diaphragm 20 is coupled to the upper portion of the frame 10. Further, an outer peripheral portion of the upper cover 90 is coupled to the upper surface of the diaphragm 20. In the present embodiment, the frame 10 is formed in a cylindrical shape as a whole, and has a power supply terminal connecting portion (not shown) for supplying power from the outside, and a lead wire for supplying power to the sound coil 30 is coupled to the power supply terminal connecting portion. (not shown). Of course, in the case of other embodiments, the cross-sectional profile of the frame 10 may be a quadrilateral shape, an elliptical shape, or a track shape. In each case, 11 201129122 internal components can also be appropriately deformed according to their external shape. The outer peripheral portion of the diaphragm 20 is fixed to the upper portion of the frame 1A. It is circular and usually consists of a polymer compound. The diaphragm 2 is driven up and down to generate sound pressure that people can hear. In the present embodiment, the _2G is divided into a _ portion of the _ and an outer portion of the outer portion with reference to the boundary portion of the three parts of the sound (four). The inner portion and the outer portion are respectively formed as a 'dome' boundary portion which is flat. The outer part is also (♦). The diaphragm 20 can be formed in a specific shape, material f, and thickness. The acoustic coil 30 is fixed to the lower surface of the diaphragm 20. The upper end portion of the voice coil 3 is fixed below the boundary portion of the diaphragm 2G. The voice coil % is curled in such a manner as to flow a current in a direction perpendicular to the magnetic lines of force. The voice coil 30 receives current from the outside. The lower portion of the sound coil 30 is located in the upper and lower side of the permanent magnet 60 and the flat plate 70 and the side wall sandwich space of the magnetic core. Such a mezzanine space is also referred to as a magnetic gap. The sound coil 3 is moved in the up and down direction in accordance with the correlation between the magnetic fields generated by the permanent magnets 6 在 in the case of sound _ such as a streaming audio signal. Thereby, the diaphragm 20 combined with the voice coil 30 vibrates to generate audio. Further, the multi-function microspeaker according to the present invention is provided with a weight member 80 〇 the weight member 80 is coupled to the lower surface of the suspension 40. Specifically, it is coupled to the lower surface of the mounting portion 412 of the main suspension portion 41. The weight member 8〇 12 201129122 is bonded to the suspension 40. The weight member 80 and the suspension 40 together constitute a vibrator that generates a vibration signal. The resonance frequency and the vibration force can be adjusted by adjusting the degree of elasticity of the suspension 40 constituting the vibrator and the weight of the weight member 80. Next, the action and effect of the multi-function micro-speaker according to the present invention having the above configuration will be described in detail. The yoke 50 to which the permanent magnet 60 and the flat plate 70 are coupled is sandwiched between the main suspension portion 41 and the sub-suspension portion 42 to be joined. The bottom portion 51 of the yoke 50 is fixed to the mounting portion 412 of the main suspension portion 41, and the upper end portion of the yoke 52 is fixed to the joint portion 422 of the sub-suspension portion 42. Therefore, the lower end portion and the upper end portion of the yoke 50 are maintained in a state in which the suspension 40 is formed in a two-stage configuration. Therefore, even if the suspension 40 continues to vibrate, the position of the magnetic vehicle 50 can be stably maintained. Further, the suspension 40 is formed into a two-stage structure of the main suspension portion 41 and the sub-suspension portion 42 to support the lower end portion and the upper end portion of the yoke 50, respectively, thereby providing the dispersion yoke 50 and the permanent magnet 60 when the suspension 40 vibrates. And the effect of the weight of the tablet 70. Conventionally, in the multi-function microspeaker 100, the yoke 105, the permanent magnet 104, and the flat plate 103 are disposed on the upper side of the first suspension 106. Therefore, the first suspension 106 needs to support the weight of the magnetic vehicle 50, the permanent magnet 103, and the flat plate 103 on the lower side of the yoke 105, thereby causing the weight applied to the first suspension 106 to be increased, thereby continuing in the first suspension 106. It is easy to break when vibrating. On the other hand, in the multi-function microspeaker 200 of the present invention, the weight of the yoke 50, the permanent magnet 60, and the flat plate 70 is supported by the main suspension portion 41 on the lower side, and is supported by the sub-suspension portion 42 on the upper side, so that 13 201129122 is provided for dispersion. The effect of weight. Further, when the yoke 50 is positioned at the attaching portion 412 of the main suspension portion 41, the upper end portion of the yoke 50 can be fixed to the joint portion 422, so that the positioning of the magnetic vehicle 50 can be easily performed. Further, the position of the magnetic vehicle 50 can be always maintained at the same position, thereby reducing variations in product characteristics, and facilitating the bonding of the yoke 50 to shorten the manufacturing time. Further, according to the multi-functional microspeaker of the present invention, unlike the case where the first suspension 106 and the second suspension 108 are conventionally used, only one suspension 40 is used, thereby reducing the number of constituent parts of the multifunctional microspeaker and reducing the number of constituent members. The cost is required, and the manufacturing process is simplified to reduce manufacturing time. The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments described above, and various modifications may be made without departing from the scope of the invention. Therefore, the true technical protection scope of the present invention should be defined by the technical idea of the scope of the appended claims. For example, the number of the support frames of the main suspension portion can be variously deformed, and the number of the sub-suspension portions can be deformed into various types. Further, a weight member is used in the embodiment of the invention, but a magnet may be used instead of the weight member.
