[0050] 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. The description is as follows:

[0051] Please refer to Figures 1 to 6 As shown in the figure, the utility model provides a shock-absorbing speaker 1, which can be a thin and long speaker and includes: a thin and long speaker seat 11, a diaphragm 12, a voice coil 13, a magnetic return component 14 and a metal spring 15, and the voice coil 13 and the magnetic return component 14 can be circular or track-shaped.

[0052] The diaphragm 12 is disposed on the top of the thin and long speaker seat 11 .

[0053] The voice coil 13 is disposed inside the thin and long speaker seat 11 and connected to the bottom of the diaphragm 12. The voice coil 13 includes a coil 131, a frame 132 and two silk threads 133. The coil 131 is wound outside the frame 132. Each silk thread 133 electrically connects the coil 131 and the conductive welding sheet 111 at the bottom of the thin and long speaker seat 11. The top of the frame 132 is connected to the bottom of the diaphragm 12. Since each silk thread 133 has strength and toughness, the vibration-damping speaker 1 can be prevented from breaking due to excessive amplitude under high power.

[0054] The magnetic return component 14 is arranged on the inner side of the thin and long speaker seat 11, and the magnetic return component 14 includes a magnetic base 141 and a magnetic unit 144. The magnetic unit 144 is arranged on the magnetic base 141. The magnetic unit 144 may have a magnetic plate 142 and a magnet 143. The magnet 143 is arranged on the magnetic base 141, and the magnetic plate 142 is arranged on the magnet 143. The magnetic base 141 may be a U iron. The voice coil 13 is movably arranged outside the magnetic unit 144 and is located between the magnetic unit 144 and the magnetic base 141.

[0055] The metal spring 15 connects the thin and long speaker seat 11 and the magnetic return component 14. The metal spring 15 includes a central portion 151, two positioning portions 152 and a plurality of elastic arms 153. The central portion 151 is disposed on the magnetic conductive seat 141. The positioning portions 152 are respectively disposed at the bottom of the two short sides of the thin and long speaker seat 11. The elastic arms 153 are respectively disposed between the central portion 151 and the positioning portions 152. The positioning portions 152 and the elastic arms 153 are symmetrically disposed on both sides of the central portion 151 so that the magnetic return component 14 does not directly contact the thin and long speaker seat 11. The number of the elastic arms 153 can be four (but the number is not limited to four), and the metal spring 15 can be made of stainless steel, beryllium copper alloy or carbon steel, among which stainless steel is a preferred material.

[0056] When the shock-absorbing speaker 1 is used, it can be combined with a sound box (not shown). After the silk threads 133 of the voice coil 13 receive the external electronic signals input by the conductive welding sheets 111, the electromagnetic action of the voice coil 13 cooperates with the magnetic return assembly 14 to drive the diaphragm 12 to move through the magnetic base 141 of the magnetic return assembly 14, the magnetic plate 142 and the magnetic force provided by the magnet 143, thereby increasing the volume of the shock-absorbing speaker 1 during operation.

[0057] When the shock-absorbing speaker 1 performs the above-mentioned operation, the elastic arms 153 provided on the metal spring sheet 15 prevent the thin and long speaker seat 11 and the magnetic return component 14 from directly contacting each other, so the elastic arms 153 can be used as a buffer between the thin and long speaker seat 11 and the magnetic return component 14, so that the vibration frequency of the magnetic return component 14 can be close to the vibration frequency of the thin and long speaker seat 11 but the phase is opposite, and the vibration of the thin and long speaker seat 11 is reduced when the shock-absorbing speaker 1 is in operation, so as to improve the stability of the shock-absorbing speaker 1 in operation, thereby exerting a better shock-absorbing effect. In addition, the metal spring sheet 15 can be used as a buffer between the thin and long speaker seat 11 and the magnetic return component 14 to avoid the kinetic energy feedback generated by the vibration of the magnetic return component 14, and achieve the effect of shock absorption and isolation when the shock-absorbing speaker 1 is in operation, thereby avoiding discomfort to the user when using the electronic device.

[0058] In addition to the above embodiments, in one embodiment of the present invention, an assembly portion 112 may be provided on both sides of the thin and long speaker seat 11, and each positioning portion 152 may be attached to each assembly portion 112 by pasting. In addition, each assembly portion 112 may be provided with a convex body 1121, and each positioning portion 152 may be provided with a notch 1521, and each positioning portion 152 is provided on each convex body 1121 of each assembly portion 112 with each notch 1521. In this way, the shock-absorbing speaker 1 of the present invention can make each positioning portion 152 of the metal spring 15 stably disposed on the assembly portion 112 of the thin and long speaker seat 11, so as to increase the stability of each elastic arm 153 when acting as a buffer.

[0059] In addition to the above embodiments, in one embodiment of the present invention, the central portion 151 may be a hollow ring, and the central portion 151 may be disposed at the bottom of the magnetic base 141. In this way, the shock-absorbing speaker 1 of the present invention can prevent the thin and long speaker base 11 from directly contacting the magnetic return assembly 14 through the cooperation between the central portion 151 and the elastic arms 153, so that the elastic arms 153 can be used as a buffer between the thin and long speaker base 11 and the magnetic return assembly 14 to absorb (consume) the kinetic energy generated by the vibration of the thin and long speaker base 11, and reduce the vibration of the thin and long speaker base 11 when the shock-absorbing speaker 1 is in operation, so as to improve the stability of the shock-absorbing speaker 1 during operation, and thus exert a better shock-absorbing effect, so as to avoid the diaphragm 12 and the voice coil 13 from being skewed, polarized, and other distortions when high power output is generated.

[0060] In addition to the above embodiments, in one embodiment of the present invention, the center portion 151 may be a hollow annular ring or a solid circle, and the metal spring 15 may be integrally formed or two symmetrical bodies connected to each other. The center portion 151 of each symmetrical body may be two circular arc bodies connected to each other or two semicircular bodies connected to each other. Since the weight of the metal spring 15 affects the vibration frequency, different types of center portions 151 may be selected according to the weight requirements during actual use to adjust the weight of the metal spring 15 to determine the appropriate vibration frequency.

[0061] In addition to the above embodiments, in one embodiment of the present invention, each elastic arm 153 is symmetrically disposed between the central portion 151 and each positioning portion 152, and the angle between the connection between each elastic arm 153 and the central portion 151 and the horizontal axis of the rectangular coordinate can be 40 degrees to 60 degrees. In this way, the shock-absorbing speaker 1 of the present invention can make each elastic arm 153 have a better buffering effect, and can achieve a better balance when vibrating, thereby producing the maximum vibration reduction effect.

[0062] In addition to the above embodiments, in one embodiment of the present invention, each elastic arm 153 may be provided with a curved portion 1531, each curved portion 1531 may be S-shaped, and 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 shock-absorbing speaker 1 of the present invention can stably arrange each elastic arm 153 between the central portion 151 and each positioning portion 152. In addition, the longer the length of each elastic arm 153, the larger the curvature of each curved portion 1531, or the more the number of each curved portion 1531, the more displacement of the metal spring 15 can be increased. Therefore, the present invention can adjust the vibration frequency and amplitude (displacement) through the curved portion 1531 of each elastic arm 153 to increase the stability of each elastic arm 153 when used as a buffer.

[0063] Please refer to Figure 7 and Figure 8 As shown in the figure, in addition to the above embodiments, in one embodiment of the present invention, the central portion 151 may be a hollow ring, and the bottom of the magnetic base 141 may be provided with an annular stopper 1411, so that the bottom of the magnetic base 141 forms an annular step, and the central portion 151 is provided on the annular stopper 1411. In this way, the shock-absorbing speaker 1 of the present invention can make the central portion 151 easy to align and firmly fit to the magnetic base 141 through the annular stopper 1411, thereby improving the assembly efficiency of the metal spring 15 and the magnetic return assembly 14.

[0064] Please refer to Fig. 9 and Fig.10 As shown in the figure, in addition to the above embodiment, in one embodiment of the present invention, the central portion 151 may be a hollow ring, and the periphery of the bottom of the magnetic base 141 may be convexly provided with an annular extension portion 1412, and the central portion 151 may be provided on the annular extension portion 1412. In this way, the shock-absorbing speaker 1 of the present invention can make the central portion 151 easy to align and firmly combine with the magnetic base 141 through the annular extension portion 1412, thereby improving the assembly efficiency of the metal spring 15 and the magnetic return component 14, and at the same time maintaining the magnetic return component 14 at a predetermined height position.

It should be noted that all changes and substitutions equivalent to the embodiment should be included in the scope of the present invention.
