Parts improve durability.
通常，揚聲器是將電信號轉換為聲音信號的裝置。微型揚聲器是主要使用於尺寸小的音頻設備例如手機、筆記本電腦、MP3播放器、耳機等近年來需求量大幅增多的便携式音頻設備中之小型揚聲器。 Typically, a speaker is a device that converts an electrical signal into a sound signal. Microspeakers are small speakers that are mainly used in small-sized audio devices such as mobile phones, notebook computers, MP3 players, and earphones, which have been in great demand in recent years.
但是，具備微型揚聲器的近年來電子產品，特別是手機之類的移動通信終端裝置大部分構成係用於產生振動信號的結構。這樣的振動信號用來代替來電信號音或者在向畫面直接輸入信息的觸摸屏中確認輸入狀態。 However, in recent years, electronic products including micro-speakers, in particular mobile communication terminal devices such as mobile phones, are mostly configured to generate 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 screen.
根據本發明的微型揚聲器是具備發生聲音基本功能的同時，還具備用於產生振動信號結構的揚聲器。微型揚聲器被稱為多功能傳動裝置或多功能電子音頻轉換器等。 The microspeaker according to the present invention is provided with a speaker for generating a vibration signal structure while having a basic function of generating sound. Micro-speakers are called multi-function transmissions or multi-function electronic audio converters.
以往的微型揚聲器為透過使由扇葉彈簧支承的振動器諧振而獲得振動的結構。在這樣習知一般的微型揚聲器 中，在具有又稱為收集板的隔膜的一側的磁性電路上具有聲音線圈，當向該聲音線圈施加聲音信號用電流時輸出音頻，當向該聲音線圈施加振動信號用電流時在振動器上產生振動。 A conventional microspeaker has a structure in which vibration is obtained by resonating a vibrator supported by a blade spring. Such a conventional micro speaker In the magnetic circuit having one side of the diaphragm, which is also called a collecting plate, there is a sound coil, and when a current for applying a sound signal is applied to the sound coil, audio is output, and when a current for a vibration signal is applied to the sound coil, the vibrator is Vibration is generated on it.
第1圖表示習知微型揚聲器的一例。參照第1圖，微型揚聲器200包括：框架210、發聲用隔膜201、聲音線圈202、以上下方向配置有N極和S極的永久磁鐵204、平板203、磁軛205、第一懸架206、第二懸架208、上框架207、配重部件209。 Fig. 1 shows an example of a conventional microspeaker. Referring to Fig. 1, the microspeaker 200 includes a frame 210, a sounding diaphragm 201, a voice coil 202, a permanent magnet 204 in which an N pole and an S pole are arranged in the upper and lower directions, a flat plate 203, a yoke 205, a first suspension 206, and a first The second suspension 208, the upper frame 207, and the weight member 209.
該聲音線圈202的上端部固定在隔膜201的下面。聲音線圈202以電流能夠向與磁力線垂直方向流動的方式被捲繞。平板203固定於永久磁鐵204的上面，永久磁鐵204固定於磁軛205的底面，該磁軛205固定於第一懸架206。第一懸架206由該框架210彈性支承。該磁軛205、永久磁鐵204及平板203形成揚聲器的磁性電路。 The upper end portion of the voice coil 202 is fixed to the lower surface of the diaphragm 201. The voice coil 202 is wound in such a manner that a current can flow in a direction perpendicular to the magnetic lines of force. The flat plate 203 is fixed to the upper surface of the permanent magnet 204, and the permanent magnet 204 is fixed to the bottom surface of the yoke 205, and the yoke 205 is fixed to the first suspension 206. The first suspension 206 is elastically supported by the frame 210. The yoke 205, the permanent magnet 204, and the flat plate 203 form a magnetic circuit of the speaker.
下面，對具有如上結構的微型揚聲器200的動作進行說明。 Next, the operation of the microspeaker 200 having the above configuration will be described.
向聲音線圈202施加適於音頻的電流時，在聲音線圈202上產生電磁力，由此隔膜201發生振動而輸出音頻。 When a current suitable for audio is applied to the voice coil 202, an electromagnetic force is generated on the voice coil 202, whereby the diaphragm 201 vibrates to output audio.
即，從永久磁鐵204的N極發出的磁力線依次透過平板203、聲音線圈202及磁軛205而形成朝向永久磁鐵204S極的磁場。此時，在聲音線圈202上發生電磁力時與由磁性電路產生的磁通產生相互作用，固定於聲音線圈202的隔膜201進行振動，從而實現輸出音頻的揚聲器功能。 That is, the magnetic lines of force emitted from the N pole of the permanent magnet 204 sequentially pass through the flat plate 203, the voice coil 202, and the yoke 205 to form a magnetic field toward the pole of the permanent magnet 204S. At this time, when an electromagnetic force is generated on the voice coil 202, an interaction with the magnetic flux generated by the magnetic circuit occurs, and the diaphragm 201 fixed to the voice coil 202 vibrates, thereby realizing a speaker function for outputting audio.
另外，向聲音線圈202施加適於振動的電流(普通低頻電流)時，透過由磁軛205、永久磁鐵204及平板203構成的磁性電路部(振動器)的上下運動而產生振動信號。 Further, when a current suitable for vibration (normal low-frequency current) is applied to the voice coil 202, a vibration signal is generated by the vertical movement of the magnetic circuit portion (vibrator) including the yoke 205, the permanent magnet 204, and the flat plate 203.
下面，對如上結構的微型揚聲器200的組裝過程進行說明。 Next, the assembly process of the microspeaker 200 constructed as above will be described.
首先，框架210由形成側壁的上部側壁框架212和下部側壁框架213及形成底面的底面框架211構成。將底面框架211黏接在下部側壁框架213上，將第二懸架208的外周部固定在該下部側壁框架213上。並且，將該上部側壁框架212固定在該下部側壁框架213的上側。此時，在上部側壁框架212和下部側壁框架213之間固定第一懸架206。 First, the frame 210 is composed of an upper side wall frame 212 and a lower side wall frame 213 which form a side wall, and a bottom frame 211 which forms a bottom surface. The bottom frame 211 is adhered to the lower side wall frame 213, and the outer peripheral portion of the second suspension 208 is fixed to the lower side wall frame 213. Further, the upper side wall frame 212 is fixed to the upper side of the lower side wall frame 213. At this time, the first suspension 206 is fixed between the upper side wall frame 212 and the lower side wall frame 213.
接著，在懸架206上依次結合並層疊磁軛205、永久磁鐵204、平板203。然後，在該上部側壁框架212的上側邊緣黏接隔膜201，在該隔膜201的上部黏接上側蓋207。通常，構成部件之間是透過黏接劑進行結合的，金屬材料的構成部件之間是透過焊接進行組裝的。 Next, the yoke 205, the permanent magnet 204, and the flat plate 203 are bonded and laminated in this order on the suspension 206. Then, the diaphragm 201 is bonded to the upper side edge of the upper side wall frame 212, and the upper side cover 207 is adhered to the upper portion of the diaphragm 201. Usually, the constituent members are bonded by an adhesive, and the constituent members of the metallic material are assembled by welding.
如上該，習知的微型揚聲器200是為了結合各個構成部件而需要進行多個程序，因此非常不方便。另外，組裝程序的難度又大，在組裝時需要花費相當多的時間，因此存在生產性降低的問題。 As described above, the conventional microspeaker 200 is required to perform a plurality of programs in order to combine the respective constituent members, and thus is extremely inconvenient. In addition, the assembly procedure is difficult, and it takes a considerable amount of time to assemble, so there is a problem that productivity is lowered.
特別是，作為組裝構成部件的方式，一般適用的是在部件之間塗敷黏接劑並將其硬化的方式，但是由於液體型黏接劑的定量及調整到正確位置的難度較大，因此在產品 特性上出現偏差。另外，為了解決這樣的問題會導致組裝設備的投資費用增加的問題。 In particular, as a method of assembling the constituent members, a method of applying an adhesive between the members and hardening them is generally applicable, but since the liquid type adhesive is quantitatively adjusted and adjusted to the correct position, it is difficult. In the product There is a deviation in characteristics. In addition, in order to solve such a problem, there is a problem that the investment cost of the assembly equipment increases.

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10上的隔膜20；固定於該隔膜20下面的聲音線圈30；第一懸架40，其具有彈性，且在該框架10上結合有外周部，在中央部形成有通孔42；磁軛(yoke)50，其固定在該第一懸架40上，並具有底面51和從該底面51邊緣向上方延伸的側面52及從該側面52的上端部向外側折彎的折彎部53；固定於該磁 軛50底面51的永久磁鐵60；固定於該永久磁鐵60上面的板(plate)70；以及向該第一懸架40的下方隔開距離配置，且具有彈性的第二懸架80，其中，該磁軛50嵌入該通孔42中，該折彎部53固定於該第一懸架40，該磁軛50的底面51與該第二懸架80結合。 First, referring to Fig. 2, a multifunctional microspeaker according to an embodiment of the present invention includes: a frame 10; a diaphragm 20 having an outer peripheral portion fixed to the frame 10; a sound coil 30 fixed to the underside of the diaphragm 20; and a first suspension 40 It has elasticity, and a peripheral portion is coupled to the frame 10, and a through hole 42 is formed in the center portion; a yoke 50 is fixed on the first suspension 40, and has a bottom surface 51 and a bottom surface 51 a side surface 52 extending upward from the edge 51 and a bent portion 53 bent outward from the upper end portion of the side surface 52; fixed to the magnetic a permanent magnet 60 of the bottom surface 51 of the yoke 50; a plate 70 fixed to the upper surface of the permanent magnet 60; and a second suspension 80 disposed at a distance from the lower side of the first suspension 40 and having elasticity, wherein the magnetic The yoke 50 is embedded in the through hole 42 . The bent portion 53 is fixed to the first suspension 40 , and the bottom surface 51 of the yoke 50 is coupled to the second suspension 80 .
根據本發明的實施例的多功能微型揚聲器的主要特徵之一是懸架的結構。為了將結合有永久磁鐵60和平板70的磁軛50容易地與第一懸架40和第二懸架80進行組裝，根據本實施例的第一懸架40和第二懸架80具有如下結構。下面，首先對第一懸架和第二懸架的結構進行說明。 One of the main features of the multifunctional microspeaker according to an embodiment of the present invention is the structure of the suspension. In order to easily assemble the yoke 50 incorporating the permanent magnet 60 and the flat plate 70 with the first suspension 40 and the second suspension 80, the first suspension 40 and the second suspension 80 according to the present embodiment have the following structure. Next, the structure of the first suspension and the second suspension will be described first.
如第2圖及第3圖所示，該第一懸架40具有彈性，在其中央部形成有通孔42，在邊緣具有朝向下側折彎的隔離部41。 As shown in FIGS. 2 and 3, the first suspension 40 has elasticity, and has a through hole 42 formed in a central portion thereof and a partition portion 41 bent toward the lower side at the edge.
該通孔42形成為僅使磁軛50的底面51透過而不使磁軛50的折彎部53透過的尺寸。透過該通孔42，磁軛52的底部51被嵌入。在組裝該第一懸架40和磁軛50時，借助於該通孔42而容易進行磁軛50的定位。 The through hole 42 is formed to transmit only the bottom surface 51 of the yoke 50 without transmitting the bent portion 53 of the yoke 50. Through the through hole 42, the bottom 51 of the yoke 52 is embedded. When the first suspension 40 and the yoke 50 are assembled, the positioning of the yoke 50 is easily performed by means of the through hole 42.
該隔離部41產生確保第一懸架40和第二懸架80之間空間的作用。因此，透過該隔離部41，在不使用另外隔離物的情况下也能夠確保第一懸架40和第二懸架80之間的空間。 This partition 41 produces a function of securing a space between the first suspension 40 and the second suspension 80. Therefore, the space between the first suspension 40 and the second suspension 80 can be ensured through the partition portion 41 without using another spacer.
第一懸架40也可稱為彈性部件、彈簧或扇葉彈簧等。在本實施例中，第一懸架40為盤形狀，並且為了與框架10的形狀對應而形成為圓盤形狀。第一懸架40由青銅等金屬 板材製造而成。另外，在其他實施例中，第一懸架40可由高分子彈性物質製造。 The first suspension 40 may also be referred to as an elastic member, a spring or a leaf spring or the like. In the present embodiment, the first suspension 40 has a disk shape and is formed in a disk shape in order to correspond to the shape of the frame 10. The first suspension 40 is made of metal such as bronze Made of sheet metal. Additionally, in other embodiments, the first suspension 40 can be fabricated from a polymeric elastomeric material.
該第二懸架80與該第一懸架40一樣具有彈性。在本實施例中，第二懸架80由與第一懸架40相同的材料構成。另外，在其他實施例中，第一懸架40和第二懸架80的材質可以互不相同。 The second suspension 80 has the same elasticity as the first suspension 40. In the present embodiment, the second suspension 80 is constructed of the same material as the first suspension 40. In addition, in other embodiments, the materials of the first suspension 40 and the second suspension 80 may be different from each other.
該第二懸架80配置在第一懸架40的下側。在該第二懸架80的邊緣結合有該第一懸架40的隔離部41。 The second suspension 80 is disposed on a lower side of the first suspension 40. A partition 41 of the first suspension 40 is coupled to an edge of the second suspension 80.
該第二懸架80具有安裝面81。 The second suspension 80 has a mounting surface 81.
該安裝面81是該第二懸架80的中央部向下側折彎的部分，該磁軛50的底面51安裝在該安裝面81上。在本實施例中，該安裝面81具備嵌入孔82，該嵌入孔82形成在安裝面81的中央部。 The mounting surface 81 is a portion where the central portion of the second suspension 80 is bent downward, and the bottom surface 51 of the yoke 50 is mounted on the mounting surface 81. In the present embodiment, the mounting surface 81 is provided with an insertion hole 82 formed at a central portion of the mounting surface 81.
該磁軛50包括底面51、側面52、及折彎部53。 The yoke 50 includes a bottom surface 51, a side surface 52, and a bent portion 53.
在本實施例中，該底面51形成為圓形，該側面52從該底面51向上側延伸。該底面51安裝在第二懸架80的安裝面81上。該磁軛50的底面51黏接或焊接在安裝面81上，或者可透過黏接膠片(未圖示)而黏接在安裝面81上。 In the present embodiment, the bottom surface 51 is formed in a circular shape, and the side surface 52 extends from the bottom surface 51 to the upper side. The bottom surface 51 is mounted on the mounting surface 81 of the second suspension 80. The bottom surface 51 of the yoke 50 is adhered or soldered to the mounting surface 81, or is adhered to the mounting surface 81 via an adhesive film (not shown).
該折彎部53是從該側面52朝向外側折彎的部分。該折彎部53固定在形成於該第一懸架40的通孔42的邊緣上。該磁軛50的折彎部53也黏接或焊接在該通孔42的邊緣上，或者透過黏接膠片(未圖示)而黏接在該通孔42的邊緣上。 The bent portion 53 is a portion that is bent outward from the side surface 52. The bent portion 53 is fixed to an edge of the through hole 42 formed in the first suspension 40. The bent portion 53 of the yoke 50 is also bonded or welded to the edge of the through hole 42 or adhered to the edge of the through hole 42 through an adhesive film (not shown).
即，該磁軛50底面51嵌入第一懸架40的通孔42之 後，安裝在第二懸架80的安裝面81上，由於折彎部53不能透過通孔42，因此以搭掛在通孔42邊緣的狀態進行固定。 That is, the bottom surface 51 of the yoke 50 is embedded in the through hole 42 of the first suspension 40. Thereafter, it is attached to the mounting surface 81 of the second suspension 80. Since the bent portion 53 cannot pass through the through hole 42, it is fixed in a state of being hung on the edge of the through hole 42.
該永久磁鐵60以與磁軛50構成同心的方式固定於磁軛50的內部底面51。為了與磁軛50的形狀對應，該永久磁鐵60形成為圓盤形狀。該永久磁鐵60黏接在磁軛50的底面51或透過黏接膠片而黏接在磁軛50的底面51。 The permanent magnet 60 is fixed to the inner bottom surface 51 of the yoke 50 so as to be concentric with the yoke 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 adhered to the bottom surface 51 of the yoke 50 or adhered to the bottom surface 51 of the yoke 50 through the adhesive film.
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。 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.
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的下部位於該空間內。 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.
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而進入磁軛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，根據由磁軛50、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。 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 yoke 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 based on the vertical movement of the magnetic circuit portion (vibrator) composed of the yoke 50, the permanent magnet 60, and the flat plate 70.
該框架10通常由塑料構成。在框架10的上部結合隔膜20的外周部。另外，在該隔膜20的上面結合上框架110的外周部。 The frame 10 is typically constructed of plastic. The outer peripheral portion of the diaphragm 20 is joined to the upper portion of the frame 10. Further, an outer peripheral portion of the frame 110 is coupled to the upper surface of the diaphragm 20.
在本實施例中，在整體上框架10形成為圓筒形狀，為了從外部供電，供電端子連接部14從外周面的一部分突出。該供電端子連接部14嵌入該外側蓋90的開放槽94中而向外部突出。向聲音線圈30供電的引線15結合在該供電端子連接部14上。 In the present embodiment, the frame 10 is formed in a cylindrical shape as a whole, and the power supply terminal connecting portion 14 protrudes from a part of the outer peripheral surface in order to supply power from the outside. The power supply terminal connecting portion 14 is fitted into the open groove 94 of the outer cover 90 to protrude to the outside. A lead 15 that supplies power to the voice coil 30 is coupled to the power supply terminal connecting portion 14.
當然，在其他實施例的情况下，框架10的橫剖面外形可以是四邊形狀、橢圓形狀、軌道形狀。在各情况下，內部部件也可根據其外部形狀而適當變形。 Of course, in the case of other embodiments, the cross-sectional shape of the frame 10 may be a quadrilateral shape, an elliptical shape, or a track shape. In each case, the inner member may be appropriately deformed according to its outer shape.
該隔膜20的外周部固定在框架10的上部。隔膜20為圓形，通常由高分子化合物構成。隔膜20進行上下振動而產生人們能夠聽到的聲壓。 The outer peripheral portion of the diaphragm 20 is fixed to the upper portion of the frame 10. The separator 20 is circular and is usually composed of a polymer compound. The diaphragm 20 vibrates up and down to generate a sound pressure that one can hear.
在本實施例中，該隔膜20以結合聲音線圈30的上端部的邊界部分為基準，分為位於內側的內側部分和位於外側的外側部分。內側部分和外側部分分別形成為拱形(dome)，邊界部分是平平的。外側部分還被稱為稜邊(edge)。隔膜20在具體形狀、材質及厚度上可進行各種變形。 In the present embodiment, the diaphragm 20 is divided into an inner portion located on the inner side and an outer side portion located on the outer side with reference to the boundary portion of the upper end portion of the acoustic coil 30. The inner portion and the outer portion are respectively formed as domes, and the boundary portions are flat. The outer portion is also referred to as an edge. The diaphragm 20 can be variously deformed in a specific shape, material, and thickness.
該聲音線圈30固定於隔膜20的下面。聲音線圈30上端部固定於隔膜20邊界部分的下面。聲音線圈30以可向與磁力線垂直的方向流動電流的方式被捲曲。聲音線圈30從外部得到供電。 The voice coil 30 is fixed to the underside of the diaphragm 20. The upper end portion of the voice coil 30 is fixed to the lower surface of the boundary portion of the diaphragm 20. The voice coil 30 is curled in such a manner as to flow a current in a direction perpendicular to the magnetic lines of force. The sound coil 30 is supplied with power from the outside.
該聲音線圈30下部位於以上下方向結合的永久磁鐵60和平板70與磁軛50的側壁夾層空間內。這樣的夾層空間又被稱為磁隙。在聲音線圈30流動音頻信號用高頻電流 時，根據由永久磁鐵60產生磁場之間的相互關係，聲音線圈30朝上下方向移動。由此，與聲音線圈30結合的隔膜20振動而產生音頻。 The lower portion of the voice coil 30 is located in the upper-side direction of the permanent magnet 60 and the flat plate 70 and the side wall sandwich space of the yoke 50. Such a sandwich space is also referred to as a magnetic gap. High frequency current for audio signal flowing in sound coil 30 At this time, the acoustic coil 30 moves in the vertical direction in accordance with the correlation between the magnetic fields generated by the permanent magnets 60. Thereby, the diaphragm 20 coupled with the voice coil 30 vibrates to generate audio.
另外，根據本發明的多功能微型揚聲器具有外側蓋90和配重部件100。 Further, the multifunctional microspeaker according to the present invention has an outer side cover 90 and a weight member 100.
該外側蓋90和第一懸架40、第二懸架80的結構特徵是本發明的重要特徵之一。該外側蓋90是為了提高微型揚聲器的構成部件的組裝性而設置的，如第2圖所示，該各構成部件層疊在外側蓋90內而進行組裝。 The structural features of the outer cover 90 and the first suspension 40 and the second suspension 80 are one of the important features of the present invention. The outer cover 90 is provided to improve the assemblability of the components of the microspeaker. As shown in FIG. 2, the components are stacked in the outer cover 90 and assembled.
具體而言，該外側蓋90具有底部91和側壁部92。在由該底部91和側壁部92構成的空間部內收納該框架10、第一懸架40等構成部件。該外側蓋90具有其上端部向內側折彎而捲曲的捲曲部93。 Specifically, the outer cover 90 has a bottom portion 91 and a side wall portion 92. Components such as the frame 10 and the first suspension 40 are housed in a space portion including the bottom portion 91 and the side wall portion 92. The outer side cover 90 has a curling portion 93 whose upper end portion is bent inward and curled.
該外側蓋90優選由不銹鋼、黃銅等金屬材料構成。該外側蓋90的捲曲部93是透過衝壓加工而形成，或者將外側蓋90向一方向旋轉的同時根據另外的加壓手段，將外側蓋90的上端部向內側加壓後透過旋製法(spinning)等多種方法來實現。 The outer cover 90 is preferably made of a metal material such as stainless steel or brass. The curling portion 93 of the outer lid 90 is formed by press working, or the outer lid 90 is rotated in one direction, and the upper end portion of the outer lid 90 is pressed inward by the other pressing means, and then the spinning method is performed. ) and other methods to achieve.
如第4圖所示，該外側蓋90的底部91上形成有用來使由第一懸架40及第二懸架80的振動而產生的空氣與外部進行通風的氣孔911。在第一懸架40及第二懸架80進行振動時，在外側蓋90內部發生空氣流動，因此如果不使產生的空氣通風，則會給第一懸架40及第二懸架80的振動產生影響。並且，可能導致諧振頻率、衰減係數的變更而 產生不完整的振動，因此需要使空氣與外部進行通風。在本實施例中，該底部91形成為圓形。不言而喻，底部91的形狀可變形為四邊形、橢圓形。 As shown in FIG. 4, the bottom portion 91 of the outer side cover 90 is formed with air holes 911 for ventilating the air generated by the vibration of the first suspension 40 and the second suspension 80 to the outside. When the first suspension 40 and the second suspension 80 vibrate, air flows inside the outer cover 90. Therefore, if the generated air is not ventilated, the vibration of the first suspension 40 and the second suspension 80 is affected. Also, it may cause a change in the resonance frequency and the attenuation coefficient. Incomplete vibrations are generated, so air and external ventilation are required. In the present embodiment, the bottom portion 91 is formed in a circular shape. It goes without saying that the shape of the bottom portion 91 can be deformed into a quadrangular shape or an elliptical shape.
該外側蓋90的側壁部92由第一側壁部921和第二側壁部922及連接部923構成。 The side wall portion 92 of the outer side cover 90 is composed of a first side wall portion 921, a second side wall portion 922, and a connecting portion 923.
該第一側壁部921從該底部91的邊緣向上側延伸，該第二側壁部922從該第一側壁部921的上端部向上側延伸。該第二側壁部922的內徑比該第一側壁部921的內徑大。該連接部923作為連接該第一側壁部921和該第二側壁部922的部分，在本實施例中是沿水平方向延伸的部分。結果，該外側蓋90形成為從底部91向上側延伸後向外側折彎，然後再向上側延伸的2段結構。 The first side wall portion 921 extends upward from an edge of the bottom portion 91, and the second side wall portion 922 extends upward from an upper end portion of the first side wall portion 921. The inner diameter of the second side wall portion 922 is larger than the inner diameter of the first side wall portion 921. The connecting portion 923 is a portion that connects the first side wall portion 921 and the second side wall portion 922, and is a portion extending in the horizontal direction in the present embodiment. As a result, the outer side cover 90 is formed in a two-stage structure in which the bottom side 91 is extended to the upper side and then bent outward, and then extended to the upper side.
該外側蓋90的側壁部92形成為能夠將構成多功能微型揚聲器的框架10、第一懸架40、第二懸架80、隔膜20的外周面全部包圍的高度。另外，在該外側蓋90的側壁部92上形成有開放槽94，以使形成在框架10上的供電端子連接部14向外側蓋90的外部突出。 The side wall portion 92 of the outer side cover 90 is formed to be able to surround the frame 10 of the multi-functional microspeaker, the first suspension 40, the second suspension 80, and the outer peripheral surface of the diaphragm 20 at all heights. Further, an opening groove 94 is formed in the side wall portion 92 of the outer side cover 90 so that the power supply terminal connecting portion 14 formed on the frame 10 protrudes to the outside of the outer side cover 90.
該配重部件100結合在該第二懸架80的下側。在該配重部件100上形成有供該安裝面81嵌入結合的聯接槽101。該配重部件100的中央部嵌入形成在該安裝面81上的嵌入孔82中。該配重部件100黏接在該第二懸架80上。 The weight member 100 is coupled to the lower side of the second suspension 80. A coupling groove 101 into which the mounting surface 81 is fitted and coupled is formed on the weight member 100. The center portion of the weight member 100 is fitted into the fitting hole 82 formed in the mounting surface 81. The weight member 100 is adhered to the second suspension 80.
該配重部件100與該第二懸架80共同構成產生振動信號的振子。透過調整構成振子的第二懸架80的彈性程度和配重部件100的重量而能夠調整諧振頻率和振動力。 The weight member 100 and the second suspension 80 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 second suspension 80 constituting the vibrator and the weight of the weight member 100.
下面，詳細說明具有如上結構的根據本發明的多功能微型揚聲器的組裝過程及作用。 Next, the assembly process and action of the multi-function microspeaker according to the present invention having the above structure will be described in detail.
首先，在隔膜20的下側結合聲音線圈30，並且透過焊接和黏接等方式，將結合有該聲音線圈30的隔膜20結合在框架10上。這樣，將結合有框架10、隔膜20及聲音線圈30的狀態稱為第一部分組裝品。 First, the voice coil 30 is bonded to the lower side of the diaphragm 20, and the diaphragm 20 to which the voice coil 30 is coupled is bonded to the frame 10 by means of welding, bonding, or the like. Thus, the state in which the frame 10, the diaphragm 20, and the voice coil 30 are combined is referred to as a first partial assembly.
接著，將構成磁性電路的磁軛50、永久磁鐵60及平板70黏接。在磁軛50的底面51上結合永久磁鐵60，在該永久磁鐵60的上面結合平板70。將第一懸架40的隔離部41和第二懸架80的邊緣結合，在該第二懸架80的下側結合配重部件100。 Next, the yoke 50, the permanent magnet 60, and the flat plate 70 constituting the magnetic circuit are bonded. A permanent magnet 60 is bonded to the bottom surface 51 of the yoke 50, and the flat plate 70 is bonded to the upper surface of the permanent magnet 60. The partition portion 41 of the first suspension 40 and the edge of the second suspension 80 are coupled, and the weight member 100 is coupled to the lower side of the second suspension 80.
接著，將結合有永久磁鐵60和平板70的磁軛50嵌入該第一懸架40的通孔42中，並且將該磁軛50的底面51安裝結合在第二懸架80的安裝面81上。這樣，將結合了磁軛50、永久磁鐵60、平板70、第一懸架40、第二懸架80、及配重部件100的狀態稱為第二部分組裝品。 Next, the yoke 50 incorporating the permanent magnet 60 and the flat plate 70 is fitted into the through hole 42 of the first suspension 40, and the bottom surface 51 of the yoke 50 is mounted and coupled to the mounting surface 81 of the second suspension 80. Thus, the state in which the yoke 50, the permanent magnet 60, the flat plate 70, the first suspension 40, the second suspension 80, and the weight member 100 are combined is referred to as a second partial assembly.
接著，從外側蓋90的底面部91依次層疊該第二部分組裝品和第一部分組裝品。並且，在該第一部分組裝品的上側結合上框架110。此時，該框架10的供電端子連結部14嵌入外側蓋90的開放槽94中。 Next, the second partial assembly and the first partial assembly are laminated in this order from the bottom surface portion 91 of the outer cover 90. And, the upper frame 110 is coupled to the upper side of the first partial assembly. At this time, the power supply terminal connecting portion 14 of the frame 10 is fitted into the open groove 94 of the outer cover 90.
接著，如第2圖所示，以將該外側蓋90的上端部捲曲而按壓該上框架110的方式形成捲曲部93，從而完成構成部件的組裝。 Next, as shown in FIG. 2, the curling portion 93 is formed by crimping the upper end portion of the outer side cover 90 and pressing the upper frame 110, thereby completing assembly of the constituent members.
如上所述，根據本發明實施例的多功能微型揚聲器能 夠將構成磁性電路的磁軛50、永久磁鐵60、平板70簡單地組裝在第一懸架40、第二懸架80上。即，將結合有永久磁鐵60及平板70的磁軛50嵌入第一懸架40的通孔42中之後安裝在第二懸架80的安裝面81上即可，因此在組裝時容易進行磁軛50的定位，故組裝簡單。 As described above, the multifunctional microspeaker according to the embodiment of the present invention can The yoke 50, the permanent magnet 60, and the flat plate 70 constituting the magnetic circuit are simply assembled to the first suspension 40 and the second suspension 80. In other words, the yoke 50 incorporating the permanent magnet 60 and the flat plate 70 is fitted into the through hole 42 of the first suspension 40, and then attached to the mounting surface 81 of the second suspension 80, so that the yoke 50 can be easily assembled at the time of assembly. Positioning, so assembly is simple.
另外，第二懸架80的安裝面81朝向下側折彎而將磁軛50的底面50夾住，因此即使第一懸架40和第二懸架80持續振動，也能夠穩定地維持磁軛50的位置。 Further, since the mounting surface 81 of the second suspension 80 is bent toward the lower side to sandwich the bottom surface 50 of the yoke 50, the position of the yoke 50 can be stably maintained even if the first suspension 40 and the second suspension 80 continue to vibrate. .
另外，將構成部件依次層疊在外側蓋90內之後將上端部捲曲而組裝構成部件，因此能夠將製造程序簡單化，提高生產性。進而，外部衝擊被外側蓋90所吸收，因此緩解給構成部件帶來的衝擊，從而提供提高耐久性的多功能微型揚聲器。 In addition, since the constituent members are sequentially laminated in the outer cover 90 and the upper end portion is crimped to assemble the constituent members, the manufacturing process can be simplified and the productivity can be improved. Further, the external impact is absorbed by the outer cover 90, thereby alleviating the impact on the constituent members, thereby providing a multifunctional microspeaker that improves durability.
另外，在第一懸架40的邊緣上形成有向下側折彎的隔離部41，因此能夠確保提供第一懸架40向上下方向移動的充分的空間，從而不需要為了確保第一懸架40和第二懸架80之間的空間而設置另外的隔離部件，因此可提供降低製造費用的效果。同時，在形成為兩段結構的外側蓋90的連結部923上安裝第二懸架80的邊緣，因此不需要用於使第二懸架80從外側蓋90的底面91隔開距離的另外的隔離部件，因此節省製造費用。 In addition, since the partition portion 41 bent downward is formed on the edge of the first suspension 40, it is possible to ensure a sufficient space for providing the first suspension 40 to move up and down, so that it is not necessary to secure the first suspension 40 and the The space between the two suspensions 80 is provided with additional isolation members, so that the effect of reducing the manufacturing cost can be provided. At the same time, the edge of the second suspension 80 is mounted on the joint portion 923 of the outer cover 90 formed into a two-stage structure, so that an additional partition member for separating the second suspension 80 from the bottom surface 91 of the outer cover 90 is not required. Therefore, manufacturing costs are saved.
另外，如上所述，在外側蓋90內層疊各個構成部件時，組裝半成品狀態的第一部分組裝品和第二部分組裝品後，透過將第一部分組裝品和第二部分組裝品層疊在外側蓋90 內而製造成品，因此與組裝個別產品相比，可達到組裝程序簡單，縮短製造時間的效果。 Further, as described above, when the respective constituent members are stacked in the outer cover 90, the first partial assembly and the second partial assembly in the semi-finished state are assembled, and then the first partial assembly and the second partial assembly are laminated on the outer cover 90. The finished product is manufactured inside, so that the assembly process can be simplified and the manufacturing time can be shortened compared with the assembly of individual products.
並且，在外側蓋90內層疊第一部分組裝品和第二部分組裝品之後，在形成捲曲部93的程序中可省略黏接劑塗敷程序，因此可減少相當大的黏接劑塗敷量。如第1圖該，以往為了將各個產品單獨地進行結合，需要第一懸架、第二懸架和框架之間的黏接過程，但是根據本發明的多功能微型揚聲器能夠省略這樣的程序。 Further, after the first partial assembly and the second partial assembly are laminated in the outer cover 90, the adhesive application procedure can be omitted in the procedure for forming the curled portion 93, so that a considerable amount of adhesive application can be reduced. As shown in Fig. 1, in the past, in order to individually bond the respective products, the bonding process between the first suspension, the second suspension, and the frame is required, but the multi-function microspeaker according to the present invention can omit such a procedure.
另外，透過形成在外側蓋90底部91的氣孔911，能夠使空氣在外側蓋90的內側和外側進行循環。在第一懸架40和第二懸架80振動時產生的空氣流動透過該氣孔911而循環，因此使得在第一懸架40和第二懸架80振動時產生的空氣流動對第一懸架40和第二懸架80的振動產生的影響最小。 Further, the air can be circulated inside and outside the outer cover 90 through the air holes 911 formed in the bottom portion 91 of the outer cover 90. Air flowing during the vibration of the first suspension 40 and the second suspension 80 circulates through the air holes 911, thereby causing air generated when the first suspension 40 and the second suspension 80 vibrate to flow to the first suspension 40 and the second suspension The vibration of 80 produces the least impact.
另外，根據本發明的多功能微型揚聲器可實現為各種變形例。 Further, the multi-function microspeaker according to the present invention can be implemented in various modifications.
例如，在本發明實施例中採用的框架上突出形成有供電端子連接部，但是也可以形成為收納於外側蓋內的形態。另外，本發明的實施例中採用了配重部件，但是也可以採用磁鐵來代替該配重部件。 For example, the power supply terminal connecting portion is formed to protrude from the frame used in the embodiment of the present invention, but may be formed to be housed in the outer cover. Further, a weight member is employed in the embodiment of the present invention, but a magnet may be used instead of the weight member.
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內可進行多種變形。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。 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.
