[0067] 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:

[0068] Please refer to Figures 1 to 6 As shown in the figure, the present invention provides a vibration-damping loudspeaker 1, which can be a thin and long loudspeaker and includes: a thin and long speaker base 11, a diaphragm 12, a voice coil 13, a magnetic return assembly 14, a metal spring 15 and a conductive spring 16. The voice coil 13 and the magnetic return assembly 14 can be circular or racetrack shaped.

[0069] The thin, elongated horn base 11 has an electrical connection part 111 on each of its two short sides.

[0070] The diaphragm 12 is located on top of the thin, elongated speaker mount 11.

[0071] The voice coil 13 is located inside the thin and long speaker mount 11. The voice coil 13 includes a coil 131 and a frame 132. The coil 131 is wound around the frame 132. The top of the frame 132 is connected to the bottom of the metal spring 15.

[0072] The magnetic return assembly 14 is located inside the thin, elongated speaker mount 11. The magnetic return assembly 14 includes a magnetic base 141 and a main magnetic unit 145. The main magnetic unit 145 is mounted on the magnetic base 141 and may have a main magnetic plate 146 and a main magnet 147. The main magnet 147 is mounted on the magnetic base 141, and the main magnetic plate 146 is mounted on the main magnet 147. The cross-section of the magnetic base 141 may be U-shaped. The voice coil 13 is movably mounted outside the main magnetic unit 145 and is located in a magnetic gap 148 between the main magnetic unit 145 and the magnetic base 141. Furthermore, the wall surrounding the magnetic base 141 may be an assembled external magnetic unit, allowing the magnetic return assembly 14 to form a dual-magnetic structure.

[0073] The metal spring 15 connects the thin and long horn base 11 and the magnetic return assembly 14. The metal spring 15 includes a central part 151, two positioning parts 152 and multiple elastic arms 153. The central part 151 is located on the magnetic base 141. Each positioning part 152 is located at the bottom of the two short sides of the thin and long horn base 11. Each elastic arm 153 is located between the central part 151 and each positioning part 152. Each positioning part 152 and each elastic arm 153 are symmetrically arranged on both sides of the central part 151 so that the magnetic return assembly 14 does not directly contact the thin and long horn base 11. The number of each elastic arm 153 can be four (but is not limited to four). The metal spring 15 can be made of stainless steel, beryllium copper alloy or carbon steel, with stainless steel being the preferred material.

[0074] The conductive spring 16 connects the thin, elongated speaker base 11, the diaphragm 12, and the voice coil 13. The conductive spring 16 includes two first conductors 161 and two second conductors 162. Each first conductor 161 is located on the outer side of the conductive spring 16, and each second conductor 162 is located on the inner side of the conductive spring 16. Each electrical connection portion 111 is electrically connected to each first conductor 161, and the two electrodes of the coil 131 are electrically connected to each second conductor 162.

[0075] When the vibration-damping speaker 1 is used, it can be combined with a speaker box (not shown). After the voice coil 131 receives the external electronic signals input from each of the electrical connection parts 111, the electromagnetic effect of the voice coil 13, in conjunction with the magnetic return assembly 14, drives the diaphragm 12 to move, thereby increasing the volume of the vibration-damping speaker 1 when it is operating.

[0076] When the vibration-damping speaker 1 operates as described above, the elastic arms 153 provided on the metal spring 15 prevent the thin, elongated speaker base 11 from directly contacting the magnetic return assembly 14. Therefore, each elastic arm 153 acts as a buffer between the thin, elongated speaker base 11 and the magnetic return assembly 14, allowing the vibration frequency of the magnetic return assembly 14 to be similar to but out of phase with the vibration frequency of the thin, elongated speaker base 11. This reduces the vibration of the thin, elongated speaker base 11 during operation, improving the stability of the vibration-damping speaker 1 and achieving a better vibration damping effect. Furthermore, the metal spring 15 acts as a buffer between the thin, elongated speaker base 11 and the magnetic return assembly 14, preventing the kinetic energy generated by the vibration of the magnetic return assembly 14 from being transmitted back, thus achieving vibration damping and isolation effects during the operation of the vibration-damping speaker 1 and preventing discomfort for the user when using electronic devices.

[0077] In addition, the conductive spring 16 can be a flexible circuit board. The wires laid in the conductive spring 16 can electrically connect each of the electrical connection parts 111 and the coil 131 of the voice coil 13. In addition to saving the assembly time of the voice coil 13, it can also provide damping to stabilize the axial movement of the voice coil 13 to avoid skewness, thereby increasing the power handling capacity of the vibration damping speaker 1 and avoiding distortion.

[0078] Please refer to Figure 3 and Figure 5 As shown in the figure, in addition to the above embodiments, in one embodiment of this utility model, each of the first conductors 161 and each of the second conductors 162 can be located on the same straight line and arranged at the center of the conductive spring 16 (for example, on the straight line connecting the centers of the two short sides of the conductive spring 16), so that each of the first conductors 161 and each of the electrical connection portions 111 are in direct face-to-face contact before spot welding is performed between them, and the two electrodes of the voice coil 13 coil 131 are directly welded to each of the second conductors 162. In this way, when the conductive spring 16 and each of the electrical connection portions 111 are welded, there is no need to consider the directionality, so that the conductive spring 16 and each of the electrical connection portions 111 can be directly positioned and joined before welding, thereby saving assembly time.

[0079] Please refer to Figure 2 and Figure 4 As shown in the figure, in addition to the above embodiments, in one embodiment of this utility model, the two short sides of the thin and elongated speaker base 11 may each be provided with an assembly portion 112, and each positioning portion 152 may be attached to the assembly portion 112 by adhesive bonding. Thus, the shock-absorbing speaker 1 of this utility model allows each positioning portion 152 of the metal spring 15 to be securely mounted on the assembly portion 112 of the thin and elongated speaker base 11, thereby increasing the stability of each elastic arm 153 when acting as a buffer. Furthermore, each positioning portion 152 may be provided with at least one overflow hole 154, and the overflow portion 1121 between each assembly portion 112 and each positioning portion 152 may be located in the overflow hole 154 of each positioning portion 152. Therefore, when the metal spring 15 is attached to the thin and elongated speaker base 11, adhesive can seep out from the overflow hole 154. In addition, when too little glue has seeped out, glue can be added through the glue overflow hole 154 to strengthen the bond.

[0080] Please refer to Figures 2 to 4As shown in the figure, in addition to the above embodiments, in one embodiment of the present invention, each electrical connection portion 111 may have an inner solder joint 1111 and an outer solder joint 1112. Each inner solder joint 1111 is electrically connected to each outer solder joint 1112. Each inner solder joint 1111 may be located at the center of the two short sides of the top of the thin elongated horn seat 11, and each outer solder joint 1112 may be located on the side of the two short sides of the bottom of the thin elongated horn seat 11 (for example, the connection between the short and long sides of the thin elongated horn seat 11). Each of the first conductors 161 can be electrically connected to each of the inner solder joints 1111, and each of the outer solder joints 1112 can be electrically connected to the external electronic wires. Each of the electrical connection parts 111 and the thin and long speaker base 11 can be integrally injection molded so that each of the inner solder joints 1111 can be exposed on the top of the thin and long speaker base 11 to electrically connect to each of the first conductors 161, and each of the outer solder joints 1112 can be exposed on the bottom of the thin and long speaker base 11 to electrically connect to the external electronic wires, thereby achieving the effect of saving assembly time.

[0081] Please refer to Figures 2 to 4 As shown in the figure, in one embodiment of the present invention, in addition to the above embodiments, the central portion 151 may be a hollow annular shape, and the central portion 151 may be located at the bottom of the magnetic base 141. Thus, the vibration-damping speaker 1 of the present invention, through the cooperation of the central portion 151 and each of the elastic arms 153, ensures that the thin, elongated speaker base 11 and the magnetic return assembly 14 do not have direct contact. Therefore, each of the elastic arms 153 can be used as a buffer between the thin, elongated speaker base 11 and the magnetic return assembly 14 to absorb (consume) the kinetic energy generated when the thin, elongated speaker base 11 vibrates, thereby reducing the vibration of the thin, elongated speaker base 11 during operation, improving the stability of the vibration-damping speaker 1 during operation, and thus achieving a better vibration damping effect, avoiding distortion problems such as skewing and polarization of the diaphragm 12 and the voice coil 13 during high-power output.

[0082] Please refer to Figures 2 to 4 As shown in the figure, in one embodiment of this utility model, in addition to the above embodiments, the central portion 151 can be a hollow annular shape or a solid circle, and the metal spring 15 can be integrally formed or two interconnected symmetrical bodies. The central portion 151 of each symmetrical body can be two interconnected arc-shaped bodies or two interconnected semicircles. Since the weight of the metal spring 15 affects the vibration frequency, different types of central portions 151 can be selected according to the weight requirements in actual use to adjust the weight of the metal spring 15 and determine the appropriate vibration frequency.

[0083] Please refer to Figures 2 to 4As shown in the figure, in one embodiment of the present invention, in addition to the above embodiments, each elastic arm 153 is symmetrically disposed between the central portion 151 and each positioning portion 152. Each elastic arm 153 may have a bent portion 1531, which may be S-shaped. One end of each elastic arm 153 is connected to the outer periphery of the central portion 151, and the other end of each elastic arm 153 is connected to the end of each positioning portion 152. In this way, the vibration-damping speaker 1 of the present invention can stably position each elastic arm 153 between the central portion 151 and each positioning portion 152. Furthermore, the longer the length of each elastic arm 153, the greater the curvature of each bending portion 1531, or the greater the number of each bending portion 1531, the greater the displacement of the metal spring 15. Therefore, this utility model can increase the stability of each elastic arm 153 as a buffer by adjusting the vibration frequency and amplitude (displacement) through the bending portion 1531 of each elastic arm 153.

[0084] Please refer to Figure 3 and Figure 4 As shown in the figure, in addition to the above embodiments, in one embodiment of the present invention, the conductive spring 16 may further include an outer connection portion 163, an inner connection portion 164, and a plurality of elastic electrical connecting arms 165. The outer connection portion 163 may be a rectangular frame, and the inner connection portion 164 may be a circular frame. The inner connection portion 164 may be located at the center of the inner side of the outer connection portion 163. Each elastic electrical connecting arm 165 is symmetrically arranged between the outer connection portion 163 and the inner connection portion 164. Each first conductor 161 may be located on the inner edge of the two short sides of the outer connection portion 163, and each second conductor 162 may be located on the outer edges of the two sides of the inner connection portion 164. Each of the flexible electrical connection arms 165 may be arc-shaped. One end of each flexible electrical connection arm 165 may be connected to the short side of the outer assembly portion 163, and the other end of each flexible electrical connection arm 165 may be connected to the outer edge of the inner assembly portion 164. Furthermore, the outer assembly portion 163 may be connected between the thin, elongated speaker mount 11 and the diaphragm 12, so that each of the first conductors 161 can be directly electrically connected to the inner solder joints 1111 of each electrical connection portion 111. Moreover, the inner assembly portion 164 may be connected between the frame 132 and the center portion 121 of the diaphragm 12, so that each of the second conductors 162 can be directly electrically connected to the two electrodes of the coil 131.

[0085] Based on the above embodiments, each of the elastic electrical connection arms 165 can provide damping to stabilize the axial movement of the voice coil 13 and increase the power handling capacity of the damped loudspeaker 1 to avoid distortion. In addition, since the conductive spring 16 also has wires laid inside to electrically connect each of the first conductors 161 of the outer connection portion 163 and each of the second conductors 162 of the inner connection portion 164, and each of the first conductors 161 and each of the second conductors 162 can be located on the same straight line, each of the first conductors 161 and the inner solder joints 1111 of each electrical connection portion 111 can directly contact each other face to face before spot welding is performed. The two electrodes of the coil 131 of the voice coil 13 can also be directly welded to each of the second conductors 162 respectively. Thus, when the conductive spring 16 is welded to the inner solder joints 1111 of each electrical connection part 111, there is no need to consider the directionality. After the conductive spring 16 is directly positioned and connected to the inner solder joints 1111 of each electrical connection part 111, the welding operation can be carried out, thereby saving assembly time.

[0086] Please refer to Figures 1 to 4 and Figure 6 As shown in the figure, in addition to the above embodiments, in one embodiment of the present invention, the two long sides of the thin and elongated speaker base 11 may each be provided with a notch 113, and the two sides of the magnetic base 141 are respectively located at each of the notches 113. In addition, the magnetic base 141 may include a magnetic base plate 144, an outer magnet 143 and an outer magnetic plate 142. The outer magnet 143 is stacked on the magnetic base plate 144, and the outer magnetic plate 142 is stacked on the outer magnet 143. The main magnetic unit 145 may be disposed in the outer magnet 143 and the outer magnetic plate 142 through a magnetic gap 148, and the voice coil 13 is movably disposed in the magnetic gap 148. The outer magnetic plate 142 may have cut-out sections 1421 on both sides, each of which can be located within the thin, elongated speaker base 11. The outer magnet 143 and the magnetic base plate 144 may each be located at the notches 113. In this way, without increasing the height of the damping speaker 1, a larger magnetic return assembly 14 can be accommodated by the notches 113. Furthermore, the notches 113 also prevent the magnetic return assembly 14 from contacting the thin, elongated speaker base 11 when the metal spring 15 is actuated, thus avoiding sound distortion.

[0087] Please refer to Figures 2 to 4As shown in the figure, in addition to the above embodiments, in one embodiment of this utility model, the central portion 151 may be a hollow annular shape, and the bottom of the magnetic base 141 may be provided with an annular limiting portion 1441, so that the bottom of the magnetic base 141 forms an annular step, and the central portion 151 is disposed on the annular limiting portion 1441. In this way, the shock-absorbing speaker 1 of this utility model can easily align and securely fit the central portion 151 to the magnetic base 141 through the annular limiting portion 1441, thereby improving the assembly efficiency of the metal spring 15 and the magnetic return assembly 14.

[0088] Please refer to Figures 2 to 4 As shown in the figure, in addition to the above embodiments, in one embodiment of the present invention, the assembly portions 112 on the two short sides of the bottom of the thin and elongated speaker base 11 may each be provided with at least one auxiliary positioning post 1122, and each positioning portion 152 may each be provided with at least one auxiliary positioning notch 155. Each auxiliary positioning post 1122 may be provided at each auxiliary positioning notch 155 to facilitate positioning each positioning portion 152 at each assembly portion 112. Thus, each positioning portion 152 and each assembly portion 112 can first be connected to each other through each glue overflow portion 1121 and each glue overflow hole 154, and then positioned by each auxiliary positioning post 1122 and each auxiliary positioning notch 155, so that the metal spring 15 can be attached to the bottom of the thin and elongated speaker base 11.

[0089] Please refer to Figure 7 and Figure 8 As shown in the figure, the inner edges of the two short sides of the thin, elongated speaker base 11 may each be provided with a bonding unit 114 (e.g., a bonding groove), and a buffer member 115 may be provided between each bonding unit 114 and the magnetic base 141. Each buffer member 115 may be made of UV adhesive. After the UV adhesive is applied between each bonding unit 114 and the magnetic base 141 and cured, it forms each buffer member 115 with softness and elasticity. Thus, each buffer member 115 can isolate the magnetic return assembly 14 from the thin, elongated speaker base 11, thereby helping to reduce vibration between them.
