[0062] In order to fully understand the purpose, features and effects of the present invention, the present invention is described in detail through the following specific embodiments and the accompanying drawings.

[0063] Please refer to Figures 1 to 8 As shown in the figure, the present invention provides a shock-absorbing speaker 1 (such as a long miniature speaker), which includes: a speaker seat 11, a three-magnetic magnetic return component 12, two elastic members 13, a diaphragm 14 and a voice coil 15. The speaker seat 11, the three-magnetic magnetic return component 12, the diaphragm 14 and the voice coil 15 can be slightly rectangular.

[0064] The speaker base 11 includes a speaker base bracket 111 and a metal bracket 112. The speaker base bracket 111 covers a portion of the outer surface of the metal bracket 112 that is molded out. The speaker base bracket 111 can be made of plastic, while the metal bracket 112 can be made of carbon steel. Thus, the speaker base 11 can utilize the combination of the speaker base bracket 111 and the metal bracket 112 to enhance the overall strength of the speaker base 11, thereby improving the resonance problem of the vibration-damping speaker 1.

[0065] The three-magnetic magnetic return assembly 12 is disposed at the bottom of the speaker base 11. The three-magnetic magnetic return assembly 12 includes a magnetic plate 121, a main magnetic unit 122, a first secondary magnetic unit 123, and a second secondary magnetic unit 124. The main magnetic unit 122 can include a main magnet 1221 and a main magnetic plate 1222 stacked on each other. The first secondary magnetic unit 123 can include a first secondary magnet 1231 and a first secondary magnetic plate 1232 stacked on each other. The second secondary magnetic unit 124 A second secondary magnet 1241 and a second secondary magnetic conductive plate 1242 may be stacked one on top of the other. The main magnetic unit 122 may be attached to the magnetic conductive plate 121 using the main magnet 1221. The first secondary magnetic conductive unit 123 may be attached to the magnetic conductive plate 121 using the first secondary magnet 1231 and spaced apart from one side of the main magnetic unit 122. The second secondary magnetic conductive unit 124 may be attached to the magnetic conductive plate 121 using the second secondary magnet 1241 and spaced apart from the other side of the main magnetic unit 122. Thus, the three-magnet magnetic return assembly 12 can utilize the cooperation of the main magnetic unit 122, the first secondary magnetic conductive unit 123, and the second secondary magnetic conductive unit 124 to provide more magnetic energy, thereby increasing the volume of the vibration-damping speaker 1 during operation.

[0066] One side of each elastic member 13 is attached to the speaker base bracket 111, and the other side of each elastic member 13 is attached to the magnetic conductive plate 121. Thus, each elastic member 13 can form a buffer between the speaker base 11 and the three-magnet magnetic return assembly 12, thereby reducing the vibration of the speaker base 11 during operation of the shock-absorbing speaker 1, thereby improving the stability of the shock-absorbing speaker 1 during operation.

[0067] The diaphragm 14 is attached to the top of the speaker stand bracket 111 and corresponds to the position of the three-magnetic magnetic return assembly 12 .

[0068] The voice coil 15 is movably disposed in the magnetic gap of the three-magnet magnetic coil assembly 12 and is attached to the bottom of the diaphragm 14 .

[0069] When the vibration-damping speaker 1 is in use, it can be combined with a speaker box (not shown). After the voice coil 15 receives an external electronic signal, the main magnetic unit 122, the first secondary magnetic unit 123, and the second secondary magnetic unit 124 cooperate to provide more magnetic energy, allowing the voice coil 15 to cooperate with the electromagnetic action of the three-magnet magnetic return assembly 12 to drive the diaphragm 14 to move, thereby increasing the volume of the vibration-damping speaker 1 during operation.

[0070] Furthermore, when the shock-absorbing speaker 1 performs the aforementioned operation, the three-magnetic magnetic return assembly 12 is suspended within the speaker base 11 due to the arrangement of the elastic members 13. Therefore, the elastic members 13 can simultaneously form a buffer between the speaker base 11 and the three-magnetic magnetic return assembly 12, thereby reducing the vibration of the speaker base 11 during operation of the shock-absorbing speaker 1, thereby improving the stability of the shock-absorbing speaker 1 during operation.

[0071] In addition to the above embodiment, in one embodiment of the present invention, each of the two long sides of the speaker base bracket 111 may be provided with at least one engaging portion 1111, and each of the two long sides of the metal bracket 112 may be provided with at least one corresponding engaging portion 1121 to engage with the engaging portion 1111. Thus, after the speaker base bracket 111 covers the portion of the metal bracket 112 that is molded out, the bonding strength between the speaker base bracket 111 and the metal bracket 112 can be further enhanced by the engaging portions 1111 and the corresponding engaging portions 1121.

[0072] In addition to the above embodiment, in one embodiment of the present invention, the two short sides of the metal bracket 112 can each be provided with a U-shaped bent section 1122, and the two short sides of the speaker base bracket 111 can each be molded around the U-shaped bent section 1122. In this way, the shape of the metal bracket 112 can be changed to match the shape of the speaker base bracket 111, thereby enhancing the strength of the speaker base bracket 111.

[0073] In addition to the above embodiments, in one embodiment of the present invention, one side of each elastic member 13 can be attached to the bottom of the speaker base bracket 111, and the other side of each elastic member 13 can be attached to the top of the magnetic conductive plate 121. Specifically, two first positioning portions 1113 can be respectively provided at the bottom of the two short sides of the speaker base bracket 111, and a second positioning portion 125 can be respectively provided at the top of the two short sides of the magnetic conductive plate 121. Each second positioning portion 125 can extend outward from the two short sides of the magnetic conductive plate 121, and both sides of each elastic member 13 can be respectively attached to the first positioning portion 1113 of the speaker base bracket 111 and the second positioning portion 125 of the magnetic conductive plate 121. Thereby, the three-magnetic magnetic return component 12 can be suspended in the speaker seat 11, so that each elastic member 13 forms a buffer between the speaker seat 11 and the three-magnetic magnetic return component 12, thereby reducing the vibration of the speaker seat 11 when the shock-absorbing speaker 1 is in operation, thereby improving the stability of the shock-absorbing speaker 1 during operation.

[0074] In addition to the above embodiment, in another embodiment of the present invention, each first positioning portion 1113 can be a column, and each second positioning portion 125 can be stepped. In this way, each elastic member 13 can be firmly combined between the speaker base 11 and the three-magnetic magnetic return assembly 12.

[0075] In addition to the above embodiment, in one embodiment of the present invention, each elastic member 13 may include two outer fixing portions 131, an inner fixing portion 132, and two U-shaped elastic portions 133. Each U-shaped elastic portion 133 is disposed between each outer fixing portion 131 and the inner fixing portion 132. Each outer fixing portion 131 may be attached to each first positioning portion 1113 at the bottom of the speaker holder bracket 111, while each inner fixing portion 132 may be attached to each second positioning portion 125 at the top of the magnetic conductive plate 121. The two sides of each U-shaped elastic portion 133 may be designed to be equal in length. The length of each U-shaped elastic portion 133 determines the vibration frequency of the three-magnet magnetic return assembly 12 (i.e., counteracts the vibration reaction force). Therefore, the length of each U-shaped elastic portion 133 can be appropriately extended to adjust the vibration frequency of the three-magnet magnetic return assembly 12 to achieve optimal vibration reduction. In this way, the shock-absorbing speaker 1 of the present invention can form a suspended state of the three-magnetic magnetic return assembly 12 in the speaker seat 11 by utilizing the elastic members 13 through the cooperation of the outer fixing portions 131, the inner fixing portion 132 and the U-shaped elastic portions 133, thereby allowing the elastic members 13 to form a buffer between the speaker seat 11 and the three-magnetic magnetic return assembly 12, thereby reducing the vibration of the speaker seat 11 when the shock-absorbing speaker 1 is in operation, thereby improving the stability of the shock-absorbing speaker 1 during operation.

[0076] In addition to the above embodiment, in one embodiment of the present invention, each outer fixing portion 131 may be provided with a fixing hole 134. Each fixing hole 134 may be correspondingly mounted on a respective column (first positioning portion 1113) at the bottom of the speaker base bracket 111. Thus, when assembling the shock-absorbing speaker of the present invention, each fixing hole 134 may be mounted on a respective first positioning portion 1113, ensuring a more stable connection after gluing.

[0077] Please refer to Figure 9 As shown in the figure, in addition to the above embodiment, in one embodiment of the present invention, a damper 17 may be provided on one surface of each U-shaped elastic portion 133 of each elastic member 13. Each damper 17 may be a coated silicone or a conformable sponge, and the shape of each damper 17 is the same as that of each U-shaped elastic portion 133. Thus, each damper 17 can enhance the shock absorption effect and appropriately adjust the kinetic energy and frequency of the vibration of each elastic member 13 to reduce the occurrence of metallic ringing sound.

[0078] In addition to the above embodiment, one embodiment of the present invention further includes two dampers 16. One side of each damper 16 can be attached to the bottom of the short side of the speaker base bracket 111, and the other side of each damper 16 can be attached to the bottom of the short side of the voice coil 15. Each damper 16 can include a first connecting portion 161, a second connecting portion 162, and two elastic portions 163. Each elastic portion 163 is disposed between the first connecting portion 161 and the second connecting portion 162. The first connecting portion 161 can be attached to the bottom of the short side of the speaker base bracket 111, and the second connecting portion 162 can be attached to the bottom of the short side of the voice coil 15. In this way, each damper 16 can maintain the axial motion of the diaphragm 14 and the voice coil 15 to prevent polarization distortion.

[0079] Please refer to Figure 10 As shown in the figure, in addition to the above-mentioned embodiment, in one embodiment of the present invention, each first positioning portion 1113 of the speaker base bracket 111 can be a column, and the outer periphery of each first positioning portion 1113 can include at least three interconnected flat surfaces 11131 and a curved surface 11132. A recess can be defined between each curved surface 11132 and two adjacent flat surfaces 11131. This facilitates alignment and sheathing between the fixing holes 134 of each outer fixing portion 131 and each first positioning portion 1113, and increases the strength of the connection between each elastic member 13 and the speaker base bracket 111.

However, those skilled in the art should understand that these embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of the present invention. It should be noted that any equivalent variations and substitutions to these embodiments are intended to fall within the scope of the present invention.
