[0079] To fully understand the purpose, features, and effects of this utility model, the following specific embodiments, in conjunction with the accompanying drawings, will provide a detailed description of this utility model:

[0080] Please refer to Figures 1 to 4 As shown in the figure, this utility model provides a shock-absorbing loudspeaker 1, which includes: an elongated speaker base 11, a sound-generating unit 12, a magnetic return assembly 13, and two metal springs 14.

[0081] The elongated horn base 11 includes two long sides 111 and two short sides 112.

[0082] The sound-generating unit 12 includes a diaphragm 121 and a voice coil 122. The diaphragm 121 is disposed on the top of the elongated speaker base 11, and the voice coil 122 is connected to the bottom of the diaphragm 121.

[0083] The magnetic return assembly 13 includes a magnetic base 131 and a magnetic unit 132. The magnetic unit 132 is disposed on the magnetic base 131. The voice coil 122 is movably disposed outside the magnetic unit 132. The magnetic unit 132 may have a magnetic plate 133 and a magnet 134. The magnet 134 is disposed on the magnetic base 131, and the magnetic plate 133 is disposed on the magnet 134. The magnetic base 131 may be U-shaped iron. The voice coil 122 is movably disposed outside the magnetic unit 132 and is located between the magnetic unit 132 and the magnetic base 131.

[0084] Each of the metal springs 14 is symmetrically connected between the elongated horn seat 11 and the magnetic base 131. Each metal spring 14 can be made of stainless steel, beryllium copper alloy, or carbon steel, with stainless steel being the preferred material. Each metal spring 14 includes two elastic arms 141, two elongated horn seat connecting portions 142, and a magnetic return assembly connecting portion 143. One end of each elastic arm 141 is connected to the elongated horn seat connecting portion 142, and the other end is connected to the magnetic return assembly connecting portion 143. Each elongated horn seat connecting portion 142 is connected to the long side portion 111 and may be adjacent to the short side portion 112. Each magnetic return assembly connecting portion 143 is connected to the two short sides of the magnetic base 131. Each elastic arm 141 has a first bending portion 1411, a second bending portion 1412, and a first connecting portion 14. 13. A second connecting portion 1414 and a third connecting portion 1415, each of the first connecting portions 1413 being connected to each of the elongated horn seat joint portions 142, each of the first bent portions 1411 being connected to each of the first connecting portions 1413, each of the second connecting portions 1414 being connected to each of the first bent portions 1411, each of the second bent portions 1412 being connected to each of the second connecting portions 1414, and each of the third connecting portions 1415 being connected to each of the second bent portions 1412 and the magnetic return assembly joint portion 143, and the bending direction of each of the first bent portions 1411 and each of the second bent portions 1412 being parallel to each of the long side portions 111.

[0085] In addition to the above embodiments, in one embodiment of the present invention, a recessed portion 113 may be provided at one end of each short side portion 112, and each recessed portion 113 may be provided with a pad 114. The voice coil 122 may be electrically connected to each pad 114. Each pad 114 is located at a different height from each long side portion 111, so that the height of each pad 114 is reduced to avoid interference with each metal spring 14. Furthermore, as... Figure 8 As shown, one end of the long side portion 111 may be provided with a recessed portion 113, and each recessed portion 113 is provided with a pad 114. The voice coil 122 can be electrically connected to each pad 114. Each pad 114 is located at a different height from each short side portion 112, so that the height of each pad 114 is reduced to avoid interference with each metal spring 14.

[0086] When the vibration-damping speaker 1 is used, it can be combined with a speaker box (not shown). After the voice coil 122 receives the external electronic signals input from each of the pads 114, the magnetic force provided by the magnetic guide seat 131 and the magnetic guide unit 132 of the magnetic return assembly 13 causes the electromagnetic effect of the voice coil 122 to work in conjunction with the magnetic return assembly 13 to drive the diaphragm 121 to move, thereby increasing the volume of the vibration-damping speaker 1 when it is operating.

[0087] When the vibration-damping speaker 1 operates as described above, due to the cooperation of the first bending portion 141, the second bending portion 1412, the first connecting portion 1413, the second connecting portion 1414, and the third connecting portion 1415 of each of the metal springs 14, the elongated speaker base 11 and the magnetic return assembly 13 do not directly contact each other. Therefore, each of the elastic arms 141 can be used as a buffer between the elongated speaker base 11 and the magnetic return assembly 13, so that the vibration frequency of the magnetic return assembly 13 can be similar to but opposite in phase with the vibration frequency of the elongated speaker base 11. This reduces the vibration of the elongated speaker base 11 when the vibration-damping speaker 1 is operating, thereby improving the stability of the vibration-damping speaker 1 during operation and achieving a better vibration damping effect. Furthermore, through the elasticity of each elastic arm 141 and the weight of the magnetic return assembly 13, the magnetic return assembly 13 can generate a specific vibration frequency (i.e., a damping frequency). This vibration frequency can be similar to but out of phase with the vibration frequency of the elongated speaker mount 11, thereby reducing the vibration of the damped speaker 1. Moreover, the metal spring 14 can act as a buffer between the elongated speaker mount 11 and the magnetic return assembly 13 to prevent the kinetic energy generated when the magnetic return assembly 13 vibrates from being transmitted back, thus achieving the effect of damping and vibration isolation when the damped speaker 1 is operating, thereby avoiding discomfort for the user when using electronic devices.

[0088] In addition to the above embodiments, in one embodiment of the present invention, each of the metal springs 14 may further include the required cushioning material in other embodiments. For example, silicone can be injection molded together with each of the metal springs 14 so that the silicone covers each of the metal springs 14, reducing the ringing sound of metal vibration and helping to reduce vibration.

[0089] In addition to the above embodiments, in one embodiment of the present invention, each of the long sides 111 of the elongated horn seat 11 may be provided with an assembly part 115 at both ends, and each elongated horn seat joint part 142 is provided in each assembly part 115. Each assembly part 115 may be provided with a first fixing post 1151 and a second fixing post 1152. Each elongated horn seat joint part 142 may be provided with a first fixing hole 1421 and a second fixing hole 1422. Each first fixing hole 1421 is correspondingly assembled with each first fixing post 1151, and each second fixing hole 1422 is correspondingly assembled with each second fixing post 1152. Each first fixing hole 1421 and each first fixing post 1151 may be assembled by gluing or by hot riveting, and each second fixing hole 1422 and each second fixing post 1152 may be assembled by gluing or by hot riveting. Thus, the shock-absorbing speaker 1 of this utility model can securely mount the elongated horn seat joint 142 of each of the metal springs 14 to each of the assembly parts 115 of the elongated horn seat 11, thereby increasing the stability of each elastic arm 141 when it acts as a buffer.

[0090] In addition to the above embodiments, in one embodiment of this utility model, each of the first fixing posts 1151 and each of the second fixing posts 1152 may have different shapes (for example, each of the first fixing posts 1151 may be square, and each of the second fixing posts 1152 may be circular), and the shape of each of the first fixing holes 1421 corresponds to the shape of each of the first fixing posts 1151, and the shape of each of the second fixing holes 1422 corresponds to the shape of each of the second fixing posts 1152. This achieves a foolproof effect by facilitating easy alignment, thereby increasing the accuracy of assembling the elongated horn seat joint 142 of each of the metal spring pieces 14 with each of the assembly parts 115 of the elongated horn seat 11.

[0091] In addition to the above embodiments, in one embodiment of this utility model, a fixing protrusion 1311 may be provided on each of the two short sides of the magnetic base 131, and the magnetic return assembly connecting portion 143 may be glued or welded to the fixing protrusion 1311. In this embodiment, the magnetic return assembly connecting portion 143 of each elastic arm 141 is connected to the magnetic base 131 on the inner surface of the vibration damping speaker 1. However, in other embodiments, it may also be connected to the outer surface of the vibration damping speaker 1, for example, to the bottom surface of each fixing protrusion 1311 of the magnetic base 131, which also prevents the elongated speaker base 11 from directly contacting the magnetic return assembly 13. In this way, each elastic arm 141 can have a better buffering effect and can achieve better balance during vibration, thereby producing the maximum vibration damping effect.

[0092] In addition to the above embodiments, in one embodiment of the present invention, each of the first bending portions 1411 and each of the second bending portions 1412 can be bent at 180 degrees, and each of the first bending portions 1411, each of the second bending portions 1412 and each of the second connecting portions 1414 can be connected to form an S-shape. Thus, the vibration-damping speaker 1 of the present invention allows each of the elastic arms 141 to increase the displacement of each of the metal spring pieces 14 through the cooperation of the first bending portions 1411, the second bending portions 1412 and the second connecting portions 1414. Therefore, the present invention can increase the stability of each of the elastic arms 141 as a buffer by adjusting the vibration frequency and amplitude (displacement) through the first bending portions 1411 and the second bending portions 1412 of each elastic arm 141.

[0093] Please refer to Figure 5 As shown in the figure, in addition to the above embodiments, in one embodiment of the present invention, at least one buffer element 15 may be provided between each of the long side portion 111 and the two sides of the magnetic base 131. Each buffer element 15 may be a type of buffer material or coated with soft glue (e.g., glue that retains its softness after curing). This avoids direct contact and abnormal sound distortion caused by excessive vibration displacement between the long speaker base 11 and the magnetic return assembly 13. This is beneficial to improving the vibration reduction effect of the vibration-damping speaker 1 of the present invention.

[0094] Please refer to Figure 6 and Figure 7 As shown in the figure, in addition to the above embodiments, in one embodiment of this utility model, an iron piece 16 may be embedded inside the elongated horn seat 11, and the connecting portions 142 of each elongated horn seat may be welded to the iron piece 16. Thus, the shock-absorbing speaker 1 of this utility model allows the elongated horn seat connecting portions 142 of each metal spring 14 to be securely mounted on the iron piece 16 of the elongated horn seat 11, thereby improving the assembly efficiency of each metal spring 14 and the elongated horn seat 11, and increasing the stability of each elastic arm 141 when acting as a buffer.

[0095] Please refer to Figure 8 and Figure 9 As shown in the figure, in addition to the above embodiments, in one embodiment of this utility model, the positions of the elastic arms 141 of each metal spring 14, the connecting portions 142 of each elongated horn seat, and the connecting portions 143 of the magnetic return assembly can be staggered to give each metal spring 14 a slightly V-shaped structural design. The shape of each metal spring 14 allows the connecting portions 142 of each elongated horn seat to connect with the long sides 111 and short sides 112 of the elongated horn seat 11. This avoids the vibration of each metal spring 14 interfering with the magnetic return assembly 13, allowing the magnetic return assembly 13 to be manufactured in a larger volume as needed. Furthermore, the elastic arms 141 of each metal spring 14 can be appropriately extended to facilitate frequency adjustment.

[0096] Please refer to Figure 10 and Figure 11 As shown in the figure, in addition to the above embodiments, in one embodiment of the present invention, the iron part 16 can be integrally injection molded into the two long sides inside the elongated horn seat 11, so that each iron part 16 can replace the first fixing post 1151 and the second fixing post 1152 of each assembly part 115. The elongated horn seat joint 142 of each metal spring 14 does not need to be provided with the first fixing hole 1421 and the second fixing hole 1422 due to the provision of each iron part 16. Thus, each elongated horn seat joint 142 can be directly welded to each iron part 16, and each magnetic return assembly joint 143 can be joined to each fixing protrusion 1311 by welding or gluing. Thus, the vibration-damping speaker 1 of this utility model can securely mount the elongated horn seat joint 142 of each metal spring 14 to the iron part 16 of the elongated horn seat 11, thereby improving the assembly efficiency of each metal spring 14 and the elongated horn seat 11 and increasing the stability of each elastic arm 141 when used as a buffer.

[0097] Please refer to Figures 12 to 14As shown in the figure, in addition to the above embodiments, in one embodiment of the present invention, each metal spring 14 may further include a connecting arm 144, the two ends of which are connected to the connecting portions 142 of each elongated horn seat, and each connecting arm 144 is respectively connected to the short side portions 112 of each elongated horn seat 11; wherein each connecting arm 144 and each elastic arm 141 have the same thickness, but the width of each connecting arm 144 is greater than that of each elastic arm 141, so that the rigidity of each connecting arm 144 is greater than that of the elastic arm 141. In this way, each metal spring 14 can be formed into a frame structure through each connecting arm 144, which can make each metal spring 14 highly rigid and difficult to bend, thereby enhancing the structural strength of each metal spring 14. Therefore, when picking up each metal spring 14 for assembly, it can achieve the effect of preventing deformation, so as to avoid the metal spring 14 being difficult to fix to the long horn seat 11 due to deformation or bending. In addition, it can also prevent the metal springs 14 from getting tangled with each other during storage, thus achieving the effect of easy access, and making it easy for each metal spring 14 to be combined with the long horn seat 11. Furthermore, since each connecting arm 144 is not connected to the magnetic return assembly 13, and the thickness of each connecting arm 144 is greater than the thickness of each elastic arm 141, and the rigidity of each connecting arm 144 is also greater than that of each elastic arm 141, each connecting arm 144 does not provide elasticity. Therefore, each connecting arm 144 does not participate in generating the damping frequency, and each connecting arm 144 has no direct relationship with damping.

[0098] In addition to the above embodiments, in one embodiment of the present invention, each short side portion 112 may be provided with a first limiting portion 1121, a second limiting portion 1122 and a third limiting portion 1123. The second limiting portion 1122 and the third limiting portion 1123 are arranged adjacent to each other. The first limiting portion 1121 is adjacent to the side of the second limiting portion 1122 and the third limiting portion 1123 and is located between the second limiting portion 1122 and the third limiting portion 1123. Each connecting arm 144 may be provided with a first engaging portion 1441 and a second engaging portion 1442 on both sides. Each first engaging portion 1441 is engaged with each first limiting portion 1121, and each second engaging portion 1442 is engaged between each second limiting portion 1122 and each third limiting portion 1123. In this way, each of the metal springs 14 can be easily aligned and securely joined to the elongated horn seat 11 by its connecting arm 144 and the junction 142 of the elongated horn seat.

[0099] Please refer to Figures 15 to 16As shown in the figure, in addition to the above embodiments, in one embodiment of the present invention, each short side portion 112 may be provided with a protrusion 1124, a first fixing portion 1125 and a second fixing portion 1126. The protrusion 1124 is provided on the short side portion 112, and the first fixing portion 1125 and the second fixing portion 1126 are provided adjacent to one side of the protrusion 1124; each connecting arm 144 is provided with a first docking portion 1443 and a second docking portion 1444.

[0100] Based on the above embodiments, each of the first docking portions 1443 can be coupled to each of the first fixing portions 1125, and each of the second docking portions 1444 can be coupled to each of the second fixing portions 1126. Furthermore, in this embodiment, each of the iron pieces 16 can replace the first fixing post 1151 and the second fixing post 1152 of each of the assembly portions 115, and the elongated horn seat connecting portions 142 of each of the metal spring pieces 14 do not need to have first fixing holes 1421 and second fixing holes 1422 due to the provision of each of the iron pieces 16. This allows each of the elongated horn seat connecting portions 142 to be directly welded to each of the iron pieces 16, and allows each of the magnetic return assembly connecting portions 143 to be coupled to each of the fixing protrusions 1311 by welding or gluing. Thus, each of the metal spring pieces 14 can be easily and securely coupled to the elongated horn seat 11 by its connecting arm 144 and the elongated horn seat connecting portion 142.
