For the sake of clear illustration, many implementation details will be described together in the following narrative. However, it should be understood that these implementation details are not used to limit the present application. That is to say, in some embodiments of the present application, these implementation details are unnecessary. In addition, for the purpose of simplifying the diagrams, some conventional structures and components will be shown in a simple schematic manner in the diagrams. In the following embodiments, the same or similar components will be denoted by the same reference numerals.

[0030] Please refer to Figures 1 to 6 , Figure 1 which is a perspective view of the loudspeaker device, Figure 2 which is another perspective view, Figure 3 which is an exploded view, Figure 4 which is another exploded view, Figure 5 which is yet another perspective view and Figure 6 which is Figure 5 a cross-sectional view taken along the line A-A' of . As shown in the figure, the present application provides a loudspeaker device 1, which includes: a magnetic conductive carrier plate 11, a magnetic circuit module 13 and a vibration module 15. The magnetic circuit module 13 includes a main magnet 131 and a sub-magnet 132. The main magnet 131 and the sub-magnet 132 are disposed on the magnetic conductive carrier plate 11, and the sub-magnet 132 is located outside the main 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 column 1512. The frame portion 1511 is disposed on the sub-magnet 132. One end of the connecting column 1512 extends downward from the frame portion 1511 through the magnetic conductive carrier plate 11, and one end of the connecting column 1512 is fixed to the magnetic conductive carrier plate 11 by hot melting. The vibration assembly 152 is disposed on the frame portion 1511. The vibration assembly 152 is located on the magnetic circuit module 13. The voice coil 153 is disposed under the vibration assembly 152. The voice coil 153 is located between the main magnet 131 and the sub-magnet 132.

[0031] In this embodiment, there are four connecting columns 1512. The connecting columns 1512 respectively correspond to the positions near the four corners of the frame portion 1511. The magnetic conductive carrier plate 11 has a carrier plate notch 111. The carrier plate notch 111 of the magnetic conductive carrier plate 11 corresponds to the connecting columns 1512, and one end of the connecting columns 1512 passes through the carrier plate notch 111. This enables the frame portion 1511 of the bracket 151 of the vibration module 15 to be stably positioned at the position of the magnetic conductive carrier plate 11 (as Figure 2As shown). Furthermore, the magnetic conductive carrier plate 11 further has a connection groove 112. The notch of the connection groove 112 is on the side away from the magnetic circuit module 13. In other words, the connection groove 112 is located at the bottom of the magnetic conductive carrier plate 11. The bottom of the connection groove 112 has a carrier plate notch 111. One end of the connection post 1512 has a connection end portion 15121. The connection end portion 15121 is fixed in the connection groove 112 by hot melting, so that the connection end portion 15121 of the connection post 1512 is deformed and completely fills the connection groove 112, so that the connection end portion 15121 and the bottom of the magnetic conductive carrier plate 11 form a flat bottom surface structure (as Figure 5 shown), so that the bracket 151 on the outside of the overall structure of the speaker device 1 can be effectively and stably fixed on the magnetic conductive carrier plate 11 at the bottom of the overall structure of the speaker device 1. After the magnetic circuit module 13 is arranged between the magnetic conductive carrier plate 11 and the vibration module 15 in the above manner, and then the bracket 151 of the vibration module 15 is fixed to the magnetic conductive carrier plate 11 by hot melting, the overall structural strength of the speaker device 1 can be enhanced, and the anti-drop effect of the speaker device 1 can be improved.

[0032] In addition, the magnetic conductive carrier plate 11 has a groove 113. The groove 113 is located on the side of the magnetic conductive carrier plate 11 where the magnetic circuit module 13 is located. The groove 113 is located between the main magnet 131 and the sub-magnet 132. Among them, there are four grooves 113. The grooves 113 are respectively arranged at both ends of the magnetic conductive carrier plate 11, and the grooves 113 extend outward respectively. The groove 113 partially corresponds to the voice coil 153. In this embodiment, the groove 113 can be used as a weight reduction structure to reduce the weight of the magnetic conductive carrier plate 11 as a whole, and provide a voice coil 153 to prevent the lead wire connecting the conductive component 19 from hitting the magnetic conductive carrier plate 11 during the operation of the speaker device, thereby affecting the sound generation of the speaker device.

[0033] In this embodiment, the magnetic circuit module 13 further includes a main magnetic conductive member 133 and a sub-magnetic conductive member 134. The main magnetic conductive member 133 is located on the main magnet 131, and the sub-magnetic conductive member 134 is located on the sub-magnet 132. The main magnetic conductive member 133 and the sub-magnetic conductive member 134 are used to concentrate the magnetic force lines of the main magnet 131 and the sub-magnet 132 to enhance the magnetic field intensity of the main magnet 131 and the sub-magnet 132. Further, the main magnetic conductive member 133 is a long plate structure corresponding to the rectangular structure of the main magnet 131, and the main magnetic conductive member 133 is a structure for assisting in strengthening the magnetic field of the main magnet 131. In addition to being used as a structure for assisting in strengthening the magnetic field of the sub-magnet 132, the sub-magnetic conductive member 134 further has an annular structure corresponding to the annular structure of the bracket 151 of the vibration module 15, and the sub-magnetic conductive member 134 can be used as an auxiliary support structure for the vibration module 15.

[0034] Furthermore, a side notch 1340 is provided on the outer side of the auxiliary magnetic conduction member 134. The side notch 1340 corresponds to the number of structures of the connecting column 1512. One end of the connecting end 15121 of the connecting column 1512 passes through the side notch 1340, so that the connecting column 1512 and the auxiliary magnetic conduction member 134 are further assembled and matched, strengthening the structural bonding strength between the vibration module 15 and the magnetic circuit module 13. Also, notches 1321 are provided at both ends of the auxiliary magnet 132. One end of the connecting end 15121 of the connecting column 1512 passes through the notch 1321. Among them, the notch 1321 of the auxiliary magnet 132 corresponds to the side notch 1340 of the auxiliary magnetic conduction member 134. In this way, the connecting column 1512 is also further assembled and matched with the auxiliary magnet 132, strengthening the structural bonding strength between the vibration module 15 and the magnetic circuit module 13, and at the same time fixing the auxiliary magnet 132 between the two connecting columns 1512.

[0035] Please refer to Figure 7 , which is Figure 6 an enlarged view of area B of

[0036] Please refer back to Figure 6 and Figure 7 , Figure 6 which is Figure 5 a sectional view taken along line A-A' of Figure 7 and Figure 6 is

[0037] Furthermore, in the present embodiment, the elastic support member 1522 is integrally formed by the connecting portion 15221, the elastic portion 15222 and the fixing portion 15223. When the sound device 1 is immersed in water, the elastic portion 15222 of the elastic support member 1522 will be pressed inward by the water pressure into the interior of the sound device 1, causing the elastic support member 1522 to concave toward the inner magnetic conduction portion 1341 of the secondary magnetic conduction member 134. The inner magnetic conduction portion 1341 is designed as a platform protruding toward the elastic support member 1522 of the vibration assembly 152. The elastic portion 15222 of the elastic support member 1522 will be structurally supported by the inner magnetic conduction portion 1341. Therefore, the influence of the external force pressing on the elastic portion 15222 of the elastic support member 1522 is reduced, and even the risk that the elastic portion 15222 of the elastic support member 1522 breaks due to excessive external force pressing is reduced.

[0038] In the present embodiment, the elastic support member 1522 of the vibration assembly 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 side wall 15111, an outer side wall 15112 and a plurality of fixing holes 15113. The plurality of fixing holes 15113 penetrate the inner side wall 15111 and the outer side 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 fixedly connected to the diaphragm member 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 side wall 15111 and the fixing portion 15223 of the frame portion 1511, and the fixing portion 15223 is formed on the inner side wall 15111, the outer side wall 15112 and the plurality of fixing holes 15113. The fixing portion 15223 is a sealing silica gel, and the connecting portion 15221 and the elastic portion 15222 are silica gel films, and the above two materials are integrally formed. The elastic support member 1522 of the present embodiment is fixed to the frame portion 1511 by an integral forming method, so that the anti-drop effect of the sound device 1 can be enhanced.

[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 side wall 15111, and the outer fixing portion 15225 is fixed to the outer side wall 15112. The outer fixing portion 15225 of the fixing portion 15223 has a convex portion 15226, and the convex portion 15226 is located on the side away from the inner fixing portion 15224. In other words, the convex portion 15226 of the outer fixing portion 15225 corresponds to the outside of the sound generating device 1. Furthermore, the convex portion 15226 has 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 both sides of the convex surface 152261, and the first inclined surface 152262 and the second inclined surface 152263 are symmetrically arranged with respect to the convex surface 152261. When the structure of the convex portion 15226 is in a state where the sound generating device 1 enters the water, the convex surface 152261, the first inclined surface 152262 and the second inclined surface 152263 can disperse the pressure for compression towards the inside of the sound generating device 1 with respect to the external water pressure, so that the pressure on the outside with respect to the convex surface 152261 is dispersed to the first inclined surface 152262 and the second inclined surface 152263, thus dispersing the water pressure on the outer fixing portion 15225 and further relieving the internal pressure of the water pressure on the sound generating device 1.

[0040] Furthermore, the outer side wall 15112 of the frame portion 1511 of the bracket 151 has an outer side groove 15114, and the outer side groove 15114 communicates with a plurality of fixing holes 15113. The outer fixing portion 15225 is filled in the outer side groove 15114 and the plurality of fixing holes 15113. Also, the outer side wall 15112 further has an outer fixing groove 15115, and the outer fixing groove 15115 is located inside the outer side groove 15114. The outer fixing groove 15115 communicates with the outer side groove 15114, and the outer fixing portion 15225 is further filled in the outer fixing groove 15115. The outer fixing groove 15115 of the present embodiment can be located above or / and below the plurality of fixing holes 15113, and can be set according to the needs of the user. The above increases the contact area of the outer side wall 15112 with respect to the outer fixing portion 15225 through the outer side groove 15114 and the outer fixing groove 15115. In this way, the structural bonding strength of the outer fixing portion 15225 formed on the outer side wall 15112 can be increased, and the non-planar structure formed by the frame portion 1511 of the bracket 151 and the fixing portion 15223 of the elastic support member 1522 is more conducive to preventing water from entering the inside of the sound generating device 1. In addition, the inner side wall 15111 of the frame portion 1511 of the bracket 151 has an inner side groove 15116, and the inner side groove 15116 communicates with a plurality of fixing holes 15113. The inner fixing portion 15224 is filled in the inner side groove 15116 and the plurality of fixing holes 15113.

[0041] In this embodiment, the elastic part 15222 serves as a connecting structure connecting the fixing part 15223 and the connecting part 15221. The elastic part 15222 has the greatest tensile toughness. It provides a structure for the connecting part 15221, the diaphragm member 1521, and the voice coil 153 to vibrate, and also serves as a structure for limiting the vibration amplitude. The outer side of the elastic part 15222 is divided into a first elastic connection side 152221 and a second elastic connection side 152222. The first elastic connection side 152221 extends and adheres to the groove wall of the inner groove 15116, and the first elastic connection side 152221 is connected to the inner fixing part 15224. The second elastic connection side 152222 extends and adheres to the side wall above the notch of the inner groove 15116. In this way, an L-shaped structure is formed and adhered to the inner side wall 15111 of the frame part 1511 to enhance the outer connection strength of the elastic part 15222.

[0042] Furthermore, the inner side of the connecting part 15221 of the elastic support 1522 wraps around the peripheral side of the diaphragm member 1521. In other words, the connecting part 15221 extends to the top surface and the bottom surface of the diaphragm member 1521. In this way, the connecting part 15221 can stably connect the diaphragm member 1521. Then, the voice coil 153 is fixed to the connecting part 15221. In this way, when the voice coil 153 vibrates under the action of the magnetic field of the magnetic circuit module 13, the voice coil 153 directly acts on the connecting part 15221 of the elastic support 1522, and the elastic support 1522 can directly bear the vibration intensity higher than that of the diaphragm member 1521. In this way, the fixing strength of the voice coil 153 is improved; in addition, as can be seen from the figure, the inner side of the connecting part 15221 wraps around the upper and lower sides of the peripheral side of the diaphragm member 1521 and extends towards the inner center of the diaphragm member 1521. Another function of this structure is to enhance the waterproof effect.

[0043] Please refer back to Figure 7 , the sound generating device 1 further includes a support ring 17, and the support ring 17 is arranged at the connection position between the inner side of the bracket 151 and the elastic part 15222. Further, the connection position of the elastic part 15222 is where the second elastic connection side 152222 extends and adheres to the side wall above the notch of the inner groove 15116. In other words, the support ring 17 is arranged at the connection position between the second elastic connection side 152222 and the inner side of the bracket 151. The support ring 17 of this embodiment can be used as a support structure for arranging a dustproof net (not shown in the figure), and the dustproof net is used to prevent dust from invading the diaphragm member 1521 and the elastic support 1522.

[0044] Please refer back to Figures 3 to 5, the loudspeaker device 1 further includes a conductive component 19. The conductive component 19 includes a conductive member 191 and a conductive circuit 192. The conductive member 191 is fixed to the bottom of the magnetic conductive carrier plate 11. One end of the conductive member 191 extends and is fixed to the secondary magnetic conductive 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 conductive carrier plate 11 is electrically connected to an external power source (not shown in the figure), and the conductive member 191 then transmits the power to the voice coil 153 through the conductive circuit 192. Further, there is a circuit notch 1343 inside the secondary magnetic conductive member 134, and one end of the conductive circuit 192 is connected to the voice coil 153 through the circuit notch 1343. This is beneficial for the conductive circuit 192 to pass through the secondary magnetic conductive member 134 and be connected to the voice coil 153. In this way, when the voice coil 153 vibrates and drives the conductive circuit 192 to vibrate, the circuit notch 1343 can reduce the interference of the vibration of the conductive circuit 192 by the secondary magnetic conductive member 134, and further avoid the situation where the conductive circuit 192 in turn affects the vibration of the voice coil 153. In this embodiment, when the voice coil 153 receives the power and changes the magnetic field, the voice coil 153 interacts with the magnetic circuit module 13, causing the voice coil 153 to vibrate, and then driving the diaphragm member 1521 and the elastic support member 1522 of the vibration component 152 to vibrate. The diaphragm member 1521 emits sound through vibration.

[0045] In summary, the present application provides a loudspeaker device. The elastic support member of the vibration component wraps around the periphery 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.
