Description of the invention: [Technical field of invention] In the multi-functional micro-speaker, more specifically, the y-mouth: functional micro-speaker: when performing the multi-functional mini-sound " The various constituent members are laminated on the outer cover in turn, and after the layer is read as a member, the upper end portion of the outer cover is crimped and assembled, thereby simplifying the assembly process, improving production efficiency, and protecting the composition in the event of an external impact. Parts improve durability. [Prior Art] Usually, 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 devices such as mobile phones, notebook computers, MP3 players, and earphones, which have been in great demand in recent years. However, in recent years, electronic products having micro-speakers, in particular, mobile communication terminal devices such as mobile phones, have largely constituted a structure for generating a vibration signal. Such a vibration signal is used to replace the incoming call signal or to confirm the wheeling state in the touch screen that directly inputs information to the screen. 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. Mini speakers are called multi-function transmissions or multi-function electronic audio converters. ▲ The 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 sound line 201129120 on a magnetic circuit having a side of a diaphragm which is also called a collecting plate, and audio is output when a current signal is applied to the sound coil, when the sound coil is applied to the sound coil. When the vibration signal uses current, it generates vibration on the vibrating body. Figure 1 shows an example of a conventional microspeaker. Referring to Fig. 1, the microspeaker 100 includes a frame 110, a sounding diaphragm 1 (n, a voice coil 102, a permanent magnet 1〇4 in which N and s poles are arranged in the upper and lower directions, a flat plate 103, a magnetic vehicle 105, and a suspension). 106. The upper frame 1〇7. The upper end portion of the s-hai sound coil 102 is fixed to the lower surface of the diaphragm 1〇丨. The voice coil 102 is wound in the up-down direction. The flat plate 1〇3 is fixed on the upper surface of the permanent magnet Sichuan 4, and the permanent magnet 1〇4 is fixed to the bottom surface of the yoke 1〇5, and the yoke 1〇5 is fixed to the suspension 1〇6. The suspension 1〇6 is elastically supported by the frame 11〇. The yoke 105, the permanent magnet 104 and the flat plate 1 〇3 forms a magnetic circuit of the speaker. Next, an operation of the microspeaker 1A 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 1, whereby the diaphragm 1 〇丨The vibration is generated and the audio is output. That is, the magnetic lines of force emitted from the N pole of the permanent magnet 104 sequentially pass through the flat plate 103, the voice coil 102, and the yoke 105 to form a magnetic field toward the S pole of the permanent magnet 1〇4. When electromagnetic force occurs on the coil 102 The magnetic flux generated by the magnetic circuit generates a mutual sound, and the film 101 of the acoustic coil 1〇2 is vibrated to realize the speaker function of outputting the audio. In addition, 'electrical vibration applied to the sound coil 102 is applied. In the case of the low-frequency current, a vibration signal is generated by the up-and-down motion of the magnetic circuit portion (vibrator) composed of the magnetic light 1〇5, the permanent magnet just and the flat plate ι〇3. 5 201129120 Description Next, the microspeaker 100 having the above structure is described.

多功能微型揚聲器1是透過將構成部件從外側蓋90的 底部92層疊而進行組裝的。具體而言，將第二隔離物150、 第二懸架130、第一隔離物80、第一懸架40、框架10、隔 膜20、及上框架120從底部92依次層疊而組裝。此時，該 框架10的供電端子連接部14嵌入外側蓋90的開放槽98 中。 在該第一懸架40的上面結合磁輛50，在磁輥50的底 面52結合第一永久磁鐵60，在該第一永久磁鐵60的上面 結合平板70。另外，在該第二懸架130的下面結合第二磁 鐵 140。 該第一懸架40的結合突起42嵌入框架10的嵌入槽12 中，第一懸架40的第一支承部44在該框架10和第一隔離 物80之間支承第一懸架40。 另外，該第二懸架130的邊緣配置於該第一隔離物80 和該第二隔離物150之間。另外，該第二懸架130的第二 支承部132在該第一隔離物80和該第二隔離物150之間穩 固地支承該第二懸架130。該第二支承部132的折彎部132a 被卡在該第一隔離物80的倒圓部82。 接著，如第3圖所示，將該外側蓋90的上端部捲曲而 形成捲曲部91，從而完成構成部件的組裝。 如上所述，根據發明實施例的多功能微型揚聲器1將 構成部件依次層疊在外側蓋90内之後將上端部捲曲而組裝 16 201129120 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，因此舒緩了構成部件帶 來的衝擊，從而提供提高耐久性的多功能微型揚聲器1。 另外，爲了確保第一懸架40和第二懸架130之間的空 間及第二懸架130和外側蓋90的底部92之間的空間而使 用第一隔離物80和第二隔離物150，從而能夠在容易確保 構成部件的空間的同時完成構成部件的組裝。 另外，爲了將框架10和第一懸架40穩定地結合，在

In addition, the second support portion 132 of the second suspension 130 stably supports the second suspension 130 between the first spacer 80 and the second spacer 150. The bent portion 132a of the second support portion 132 is caught in the rounded portion 82 of the first spacer 80. Next, as shown in Fig. 3, the upper end portion of the outer cover 90 is crimped to form the curl portion 91, thereby completing the assembly of the constituent members. As described above, the multi-functional microspeaker 1 according to the embodiment of the present invention laminates the constituent members in the outer cover 90 in order, and then crimps the upper end portion to assemble the components of the 201120112120. Therefore, the manufacturing process can be simplified and the productivity can be improved. Further, the external impact is absorbed by the outer cover 90, so that the impact of the constituent members is relieved, thereby providing the multifunctional microspeaker 1 which improves durability. In addition, in order to secure the space between the first suspension 40 and the second suspension 130 and the space between the second suspension 130 and the bottom 92 of the outer cover 90, the first spacer 80 and the second spacer 150 are used, thereby enabling It is easy to ensure the assembly of the constituent parts while ensuring the space constituting the components. In addition, in order to stably join the frame 10 and the first suspension 40, the insertion groove 12 is formed on the frame 10, and the coupling protrusion 42 is formed in the first suspension 40, thereby facilitating the combination of the frame 10 and the first suspension 40 even when subjected to In the case of an external impact, the first suspension 40 is also not detached from the frame 10. Further, the cross section of the first spacer 80 is formed in a quadrangular shape as a whole, and the corner portion is rounded, and the bent portion 132a of the second support portion 132 is sandwiched in the rounded portion 82, whereby the first spacer 80 and The second suspension 130 can also be combined easily and stably. Further, the air holes 96 formed in the bottom portion 92 of the outer cover 90 allow air to circulate inside and outside the outer cover 90. Air flowing during the vibration of the first suspension 40 and the second suspension 130 circulates through the air holes 96, thereby causing air generated when the first suspension 40 and the second suspension 130 vibrate to flow to the first suspension 40 and the second suspension The vibration of 130 is minimally affected. In addition, the first protrusion 46 formed on the first suspension 40 and the second protrusion 99 formed on the outer cover 90 prevent the first suspension 40 and the second suspension 130 from tilting to one side. Thereby, the first suspension 40 and the second suspension 130 are prevented from being broken or incompletely vibrated by 17 201129120. The versatile microspeaker according to the present invention can be realized as, for example, the electrical terminal connecting portion employed in the embodiment of the present invention, but it can also be energized. Further, each of γ is formed so as to be housed in the outer cover. In the example, the first suspension is formed separately on the first suspension, but the first support portion may not be formed. Also, in the second suspension - a second support portion is formed not so long. Further, the first suspension: the opening/shape of the wood can be changed to various shapes depending on the shape of the bottom of the outer cover. Further, in the present embodiment, the second magnet is coupled to the lower side of the second suspension, but may be coupled to the upper surface of the second suspension.
