However, it should be understood that these implementation details are not intended to limit the present application. In other words, in some embodiments of the present application, these implementation details are optional.

In the following embodiments, the same reference numerals will be used to represent the same or similar components.

[0030] See also Figures 1 to 6 , Figure 1 This is a three-dimensional diagram of the speaker system. Figure 2 Another stereogram, Figure 3 It is an exploded diagram, Figure 4 This is another exploded diagram. Figure 5 It is another stereogram and Figure 6 yes Figure 5 As shown in the figure, the present application provides a speaker device 1, which includes: a magnetic carrier plate 11, a magnetic circuit module 13, and a vibration module 15. The magnetic circuit module 13 includes a primary magnet 131 and a secondary magnet 132. The primary magnet 131 and the secondary magnet 132 are disposed on the magnetic carrier plate 11, with the secondary magnet 132 located outside the primary magnet 131. The vibration module 15 includes a bracket 151, a vibration assembly 152, and a voice coil 153. The bracket 151 includes a frame portion 1511 and a connecting post 1512. The frame portion 1511 is disposed on the secondary magnet 132. One end of the connecting post 1512 extends downward from the frame portion 1511 through the magnetic carrier plate 11. One end of the connecting post 1512 is fixed to the magnetic carrier plate 11 by heat fusion. The vibration assembly 152 is disposed on the frame portion 1511 and is located on the magnetic circuit module 13. The voice coil 153 is disposed below the vibration assembly 152 and is located between the primary magnet 131 and the secondary magnet 132.

[0031] In this embodiment, there are four connecting posts 1512, which correspond to the positions near the four corners of the frame portion 1511. The magnetic carrier 11 has a carrier notch 111, and the carrier notch 111 of the magnetic carrier 11 corresponds to the connecting posts 1512. One end of the connecting post 1512 passes through the carrier notch 111. This allows the frame portion 1511 of the bracket 151 of the vibration module 15 to be firmly positioned on the position of the magnetic carrier 11 (such as Figure 2As shown). Furthermore, the magnetic carrier plate 11 further has a connecting groove 112, the notch of the connecting groove 112 is away from the side of the magnetic circuit module 13. In other words, the connecting groove 112 is located at the bottom of the magnetic carrier plate 11, and the bottom of the connecting groove 112 has a carrier notch 111. One end of the connecting column 1512 has a connecting end 15121, and the connecting end 15121 is fixed to the connecting groove 112 by hot melt, so that the connecting end 15121 of the connecting column 1512 is deformed and completely filled in the connecting groove 112, so that the connecting end 15121 and the bottom of the magnetic carrier plate 11 form a flat bottom surface structure (as shown). Figure 5 As shown, this effectively and securely secures the outer brackets 151 of the overall structure of the speaker device 1 to the magnetic carrier plate 11 at the bottom of the overall structure. This method, in which the magnetic circuit module 13 is positioned between the magnetic carrier plate 11 and the vibration module 15 and then the brackets 151 of the vibration module 15 are fixed to the magnetic carrier plate 11 by heat-seal, strengthens the overall structural strength of the speaker device 1 and enhances its drop resistance.

[0032] Furthermore, the magnetic carrier plate 11 has a groove 113. Groove 113 is located on the side of the magnetic carrier plate 11 that includes the magnetic circuit module 13. Groove 113 is located between the primary magnet 131 and the secondary magnet 132. Four grooves 113 are provided, one at each end of the magnetic carrier plate 11. Groove 113 extends outward, and portions of groove 113 correspond to the voice coil 153. In this embodiment, groove 113 serves as a weight-reducing structure to reduce the overall weight of the magnetic carrier plate 11. Furthermore, groove 113 prevents the leads connecting the voice coil 153 to the conductive element 19 from colliding with the magnetic carrier plate 11 during operation of the speaker device, thereby affecting the sound produced by the speaker device.

[0033] In this embodiment, the magnetic circuit module 13 further includes a main magnetic member 133 and a secondary magnetic member 134. The main magnetic member 133 is located on the main magnet 131, and the secondary magnetic member 134 is located on the secondary magnet 132. The main magnetic member 133 and the secondary magnetic member 134 are used to concentrate the magnetic lines of force of the main magnet 131 and the secondary magnet 132 to enhance the magnetic field strength of the main magnet 131 and the secondary magnet 132. Furthermore, the main magnetic member 133 is a long plate structure corresponding to the rectangular structure of the main magnet 131, and the main magnetic member 133 serves as a structure that assists the main magnet 131 in strengthening the magnetic field. In addition to serving as a structure that assists in strengthening the magnetic field of the secondary magnet 132, the secondary magnetic member 134 has an annular structure that corresponds to the annular structure of the bracket 151 of the vibration module 15, and the secondary magnetic member 134 can serve as an auxiliary support structure for the vibration module 15.

[0034] Furthermore, the outer side of the secondary magnetic conductive member 134 has side notches 1340 corresponding to the number of side notches 1340 in the structure of the connecting post 1512. One end of the connecting end 15121 of the connecting post 1512 passes through the side notches 1340. This further assembles and cooperates with the secondary magnetic conductive member 134, strengthening the structural connection between the vibration module 15 and the magnetic circuit module 13. Furthermore, the secondary magnet 132 has notches 1321 at both ends. One end of the connecting end 15121 of the connecting post 1512 passes through the notches 1321. The notches 1321 of the secondary magnet 132 correspond to the side notches 1340 in the secondary magnetic conductive member 134. This further assembles and cooperates with the secondary magnet 132, strengthening the structural connection between the vibration module 15 and the magnetic circuit module 13, and also secures the secondary magnet 132 between the two connecting posts 1512.

[0035] Please also refer to Figure 7 ,yes Figure 6 : Enlarged view of area B. In this embodiment, the secondary magnetic conductive member 134 includes an inner magnetic conductive portion 1341 and an outer magnetic conductive portion 1342. The outer magnetic conductive portion 1342 is located on the outside of the inner magnetic conductive portion 1341. The height from the top surface of the inner magnetic conductive portion 1341 to the top surface of the secondary magnet 132 is higher than the height from the top surface of the outer magnetic conductive portion 1342 to the top surface of the secondary magnet 132. In other words, the height of the secondary magnetic conductive member 134 relative to one side of the vibration module 15 is such that the inner height is higher than the outer height. In addition, the frame portion 1511 of the bracket 151 is disposed on the outer magnetic conductive portion 1342, and the bottom of the bracket 151 has a fixing recess 1510, in which the outer magnetic conductive portion 1342 is fixed. This allows the frame portion 1511 of the bracket 151 and the outer magnetic conductive portion 1342 of the secondary magnetic conductive member 134 to be firmly combined and fixed.

[0036] Please refer back to Figure 6 and Figure 7 , Figure 6 yes Figure 5 The cross-sectional view of line A-A' is Figure 7 yes Figure 6 An enlarged view of area B is shown. As shown, vibration assembly 152 includes a diaphragm 1521 and an elastic support member 1522. Elastic support member 1522 is supported around diaphragm 1521 and mounted on bracket 151. Diaphragm 1521 primarily serves as the diaphragm structure in the sound-producing area of speaker 1, through which sound is primarily emitted. Elastic support member 1522 primarily serves as the ring structure in the sound-producing area of the speaker, providing an elastic space for diaphragm 1521 to vibrate upward and downward.

[0037] Furthermore, in this embodiment, the elastic support member 1522 is formed as an integral body with the connecting portion 15221, the elastic portion 15222 and the fixing portion 15223. When the speaker device 1 is immersed in water, the elastic portion 15222 of the elastic support member 1522 will be pressed toward the interior of the speaker device 1 by the water pressure, so that the elastic support member 1522 will be recessed toward the inner magnetic conductive portion 1341 of the secondary magnetic conductive member 134, and the inner magnetic conductive portion 1341 is designed to be a platform protruding toward the elastic support member 1522 of the vibration component 152. The elastic portion 15222 of the elastic support member 1522 will be supported by the structure of the inner magnetic conductive portion 1341. Therefore, the influence of external pressure on the elastic portion 15222 of the elastic support member 1522 is reduced, and even the risk of the elastic portion 15222 of the elastic support member 1522 being broken due to excessive external pressure is reduced.

[0038] In this embodiment, the elastic support member 1522 of the vibration component 152 is made by injection molding on the frame portion 1511 of the bracket 151. The frame portion 1511 of the bracket 151 has an inner wall 15111, an outer wall 15112 and a plurality of fixing holes 15113. The plurality of fixing holes 15113 penetrate the inner wall 15111 and the outer wall 15112. The elastic support member 1522 has a connecting portion 15221, an elastic portion 15222 and a fixing portion 15223. The connecting portion 15221, the elastic portion 15222 and the fixing portion 15223 of the elastic support member 1522 are integrally formed. The inner side of the connecting portion 15221 is connected to the inner side of the connecting portion 15221. The elastic support member 1522 is fixed to the diaphragm 1521. The outer side of the connecting portion 15221 is connected to the inner side of the elastic portion 15222. The outer side of the elastic portion 15222 is connected to the inner sidewall 15111 of the frame 1511 and the fixing portion 15223. The fixing portion 15223 is formed on the inner sidewall 15111, the outer sidewall 15112, and the plurality of fixing holes 15113. The fixing portion 15223 is made of sealing silicone, while the connecting portion 15221 and the elastic portion 15222 are made of silicone film, and the two materials are integrally formed. The elastic support member 1522 of this embodiment is fixed to the frame 1511 through an integral molding method, which can enhance the drop resistance of the speaker device 1.

[0039] As described above, the fixing portion 15223 includes an inner fixing portion 15224 and an outer fixing portion 15225. The inner fixing portion 15224 and the outer fixing portion 15225 are connected to each other through a plurality of fixing holes 15113. The inner fixing portion 15224 is fixed to the inner sidewall 15111, and the outer fixing portion 15225 is fixed to the outer sidewall 15112. The outer fixing portion 15225 of the fixing portion 15223 has a protrusion 15226, which is located on the side away from the inner fixing portion 15224. In other words, the protrusion 15226 of the outer fixing portion 15225 corresponds to the outer side of the speaker device 1. Furthermore, the convex portion 15226 includes a convex surface 152261, a first inclined surface 152262, and a second inclined surface 152263. The first inclined surface 152262 and the second inclined surface 152263 are located on either side of the convex surface 152261 and are symmetrically arranged relative to the convex surface 152261. When the speaker device 1 is submerged in water, the convex surface 152261, the first inclined surface 152262, and the second inclined surface 152263 can disperse the pressure of external water pressure compressing the interior of the speaker device 1, so that the external pressure relative to the convex surface 152261 is dispersed to the first inclined surface 152262 and the second inclined surface 152263. In this way, the pressure of the water pressure on the external fixing portion 15225 is dispersed, further reducing the internal pressure of the water pressure on the speaker device 1.

[0040] Furthermore, the outer wall 15112 of the frame portion 1511 of the bracket 151 has an outer groove 15114, which communicates with the plurality of fixing holes 15113. The outer groove 15114 and the plurality of fixing holes 15113 are filled with the external fixing portion 15225. Furthermore, the outer wall 15112 further has an external fixing groove 15115, which is located within the outer groove 15114 and communicates with the outer groove 15114. The external fixing portion 15225 further fills the outer fixing groove 15115. In this embodiment, the external fixing groove 15115 can be located above, below, or both of the plurality of fixing holes 15113, and can be positioned according to user needs. The outer groove 15114 and the outer fixing groove 15115 described above increase the contact area of the outer wall 15112 relative to the outer fixing portion 15225, thereby enhancing the structural bonding strength of the outer fixing portion 15225 formed on the outer wall 15112. Furthermore, the non-planar structure formed by the frame portion 1511 and the fixing portion 15223 of the elastic support member 1522 further prevents water from entering the interior of the speaker device 1. Furthermore, the inner wall 15111 of the frame portion 1511 of the bracket 151 has an inner groove 15116, which communicates with the plurality of fixing holes 15113. The inner fixing portion 15224 fills the inner groove 15116 and the plurality of fixing holes 15113.

[0041] In this embodiment, the elastic portion 15222 serves as a connecting structure connecting the fixed portion 15223 and the connecting portion 15221. Having maximum tensile toughness, the elastic portion 15222 provides a structure for vibration of the connecting portion 15221, the diaphragm 1521, and the voice coil 153, while also limiting the vibration amplitude. The outer side of the elastic portion 15222 is divided into a first elastic connecting side 152221 and a second elastic connecting side 152222. The first elastic connecting side 152221 extends toward and adheres to the inner groove 15116 wall and is connected to the inner fixed portion 15224. The second elastic connecting side 152222 extends toward and adheres to the sidewall of the inner groove 15116 above the notch. This L-shaped structure adheres to the inner sidewall 15111 of the frame portion 1511, strengthening the outer connection strength of the elastic portion 15222.

[0042] Furthermore, the inner side of the connecting portion 15221 of the elastic support member 1522 covers the circumference of the diaphragm 1521. In other words, the connecting portion 15221 extends over the top and bottom surfaces of the diaphragm 1521, thereby firmly connecting the diaphragm 1521. The voice coil 153 is then fixed to the connecting portion 15221. When the voice coil 153 vibrates due to the magnetic field of the magnetic circuit module 13, it directly acts on the connecting portion 15221 of the elastic support member 1522. The elastic support member 1522 can directly withstand vibrations at a higher intensity than the diaphragm 1521, thereby enhancing the fixing strength of the voice coil 153. Furthermore, as can be seen from the figure, the inner side of the connecting portion 15221 covers the upper and lower sides of the circumference of the diaphragm 1521 and extends toward the center of the diaphragm 1521. This structure also serves to enhance waterproofing.

[0043] Please refer back to Figure 7 The speaker device 1 further includes a support ring 17, which is disposed at the junction between the inner side of the bracket 151 and the elastic portion 15222. Specifically, the junction between the elastic portion 15222 and the inner groove 15116 is where the second elastic connection side 152222 extends and covers the sidewall above the notch. In other words, the support ring 17 is disposed at the junction between the second elastic connection side 152222 and the inner side of the bracket 151. In this embodiment, the support ring 17 can serve as a support structure for a dust screen (not shown), which is used to prevent dust from intruding into the diaphragm 1521 and the elastic support member 1522.

[0044] Please refer back to Figures 3 to 5The speaker device 1 further includes a conductive assembly 19, which includes a conductive member 191 and a conductive circuit 192. The conductive member 191 is fixed to the bottom of the magnetic carrier plate 11. One end of the conductive member 191 extends and is fixed to the secondary magnetic member 134. One end of the conductive circuit 192 is connected to one end of the conductive member 191, and the other end of the conductive circuit 192 is connected to the voice coil 153. In this embodiment, the conductive member 191 located at the bottom of the magnetic carrier plate 11 is electrically connected to an external power source (not shown). The conductive member 191 then transmits power to the voice coil 153 through the conductive circuit 192. Furthermore, the secondary magnetic member 134 has a circuit recess 1343 on its inner side. One end of the conductive circuit 192 is connected to the voice coil 153 through the circuit recess 1343. This facilitates the connection of the conductive circuit 192 to the voice coil 153 via the secondary magnetic conductive member 134. This prevents the vibration of the conductive circuit 192 from being disturbed by the secondary magnetic conductive member 134 when the voice coil 153 vibrates, thereby preventing the conductive circuit 192 from influencing the vibration of the voice coil 153. In this embodiment, when the voice coil 153 receives power to change the magnetic field, it interacts with the magnetic circuit module 13, causing the voice coil 153 to vibrate. This in turn drives the diaphragm 1521 and elastic support member 1522 of the vibration assembly 152 to vibrate, and the diaphragm 1521 vibrates to produce sound.

[0045] In summary, the present application provides a speaker device, in which the elastic support member of the vibration component covers the peripheral side of the diaphragm member, so that the diaphragm member can be firmly fixed in the middle of the bracket by the elastic support member. In this way, the connection strength between the diaphragm member and the elastic support member is high and the waterproof effect is good.
