[0048] 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.

[0049] Please refer to Figures 1 to 5 As shown in the figure, the utility model provides a shock-absorbing speaker 1, which can be a cylindrical speaker and includes: a speaker seat 11, a sound-generating component 12, a magnetic return component 13 and a shock-absorbing component 14.

[0050] The speaker seat 11 can be annular in shape, and the sound-generating component 12 includes a diaphragm 121, a voice coil 122 and a spring 123. The diaphragm 121 can be circular and arranged on the top of the speaker seat 11, the voice coil 122 can be annular and connected to the bottom of the diaphragm 121, and the spring 123 can be annular and connected between the speaker seat 11 and the voice coil 122.

[0051] The magnetic return assembly 13 can be cylindrical and include a magnetic base 131 and a magnetic unit 132. The magnetic unit 132 can be cylindrical and disposed on the magnetic base 131. The voice coil 122 is movably disposed in the magnetic gap between the magnetic unit 132 and the magnetic base 131. The magnetic base 131 can be U-shaped iron. The magnetic unit 132 can have a stacked combination of a magnetic plate 1321 and a magnet 1322, or a staggered stacked combination of two magnetic plates 1321 and two magnets 1322. In this embodiment, the magnetic unit 132 can be a staggered stacked combination of two magnetic plates 1321 and two magnets 1322.

[0052] The shock-absorbing assembly 14 connects the speaker seat 11 and the magnetic return assembly 13. The shock-absorbing assembly 14 includes a ring-shaped spring piece 141 and a fixing ring 142. The ring-shaped spring piece 141 can be annular and connected between the speaker seat 11 and the magnetic base 131. The fixing ring 142 can be annular and connected between the magnetic base 131 and the ring-shaped spring piece 141, so that the magnetic return assembly 13 does not directly contact the speaker seat 11. The ring-shaped spring piece 141 can be a metal spring piece, especially a metal material with high yield strength and fatigue resistance, including carbon steel materials such as high carbon steel or high carbon manganese steel or alloy steel materials such as stainless steel. Preferably, the ring-shaped spring piece 141 of this embodiment can be high carbon manganese steel, and the fixing ring 142 can be plastic or metal material. The material of the fixing ring 142 of this embodiment can be aluminum.

[0053] When the shock-absorbing speaker 1 is in use, it can be combined with a speaker box (not shown). After the two silk threads 1221 of the voice coil 122 receive the external electronic signal input by the conductive soldering plate 111, the magnetic force provided by the magnetic base 131 and the magnetic unit 132 of the magnetic return component 13 allows the electromagnetic action of the voice coil 122 to cooperate with the magnetic return component 13 to drive the diaphragm 121 to move, thereby causing the shock-absorbing speaker 1 to produce sound.

[0054] When the shock-absorbing speaker 1 performs the above-described operation, the annular spring 141 provided on the shock-absorbing assembly 14 prevents the speaker base 11 from directly contacting the magnetic return assembly 13. Therefore, the annular spring 141 can be used as a buffer between the speaker base 11 and the magnetic return assembly 13, so that the vibration frequency of the magnetic return assembly 13 can be close to the vibration frequency of the speaker base 11 but with an opposite phase. This reduces 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 and achieving a better shock-absorbing effect. Furthermore, the annular spring 141 can serve as a buffer between the speaker base 11 and the magnetic return assembly 13 to prevent the kinetic energy generated by the vibration of the magnetic return assembly 13 from being transferred back, thereby achieving a shock-absorbing and isolating effect during operation of the shock-absorbing speaker 1, thereby preventing discomfort to the user when using an electronic device.

[0055] Based on the description of the above embodiments, the vibration-damping speaker of the present invention can utilize the vibration-damping component 14 to increase the power handling capacity and exert a better vibration-damping effect, thereby avoiding the distortion problems such as skewness and polarization caused by the sound-generating component 12 when outputting high power.

[0056] In addition to the above embodiment, in another embodiment of the present invention, the inner periphery of the bottom of the speaker base 11 may be provided with an annular assembly groove 112, and the outer periphery of the annular spring 141 is connected to the annular assembly groove 112. In this way, the shock-absorbing speaker 1 of the present invention can firmly seat the annular spring 141 in the annular assembly groove 112 of the speaker base 11, thereby increasing the stability of the shock-absorbing assembly 14 when acting as a buffer.

[0057] In addition to the above embodiment, in one embodiment of the present invention, the magnetic base 131 may be a U-shaped iron, the inner periphery of the fixing ring 142 may be provided with a transverse assembly flange 1421, and the outer periphery of the fixing ring 142 may be provided with a longitudinal assembly flange 1422, the longitudinal assembly flange 1422 being provided below the outer periphery of the transverse assembly flange 1421. Furthermore, the annular spring 141 may include an outer ring body 1411, an inner ring body 1412, and a plurality of elastic connecting arms 1413, each elastic connecting arm 1413 connecting the outer ring body 1411 to the inner ring body 1412. In this way, the shock-absorbing speaker 1 of the present invention can be assembled with the top of the outer ring body 1411 connected to the annular assembly groove 112 at the bottom of the speaker seat 11, and the inner ring body 1412 can be sleeved on the magnetic base 131 and the top of the inner ring body 1412 can be connected to the bottom of the longitudinal assembly flange 1422, and the transverse assembly flange 1421 is connected to the top of the magnetic base 131. In this way, the shock-absorbing speaker 1 of the present invention can make the outer ring body 1411 of the shock-absorbing component 14 firmly set in the annular assembly groove 112 of the speaker seat 11, and the inner ring body 1412 cooperates with the fixing ring 142 to be firmly positioned and connected to the magnetic base 131 to improve the bonding strength, and at the same time, through each elastic connecting arm 1413, the speaker seat 11 and the magnetic return component 13 are not in direct contact, so as to improve the stability during buffering. Therefore, the shock-absorbing speaker 1 of the present invention can use the annular spring 141 and each elastic connecting arm 1413 as a buffer between the speaker seat 11 and the magnetic return component 13 to absorb (consume) the kinetic energy generated when the speaker seat 11 vibrates, and reduce the vibration of the speaker seat 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 to avoid the problems of distortion such as skewing and polarization of the diaphragm 121 and the voice coil 122 during high-power output.

[0058] In addition to the above embodiment, in one embodiment of the present invention, the number of elastic connecting arms 1413 can be three (but the number is not limited to three). In this way, the vibration-damping speaker 1 of the present invention can provide each elastic connecting arm 1413 with a better buffering effect, thereby achieving a better balance during vibration, thereby producing a maximum vibration reduction effect.

[0059] Please refer to Figures 6 to 10As shown in the figure, in addition to the above embodiments, in one embodiment of the present utility model, the magnetic base 131 can be a U-shaped iron and the outer periphery of the top of the magnetic base 131 can be provided with an annular joint flange 1311, the top of the inner periphery of the annular spring 141 is connected to the bottom of the annular joint flange 1311, and the inner periphery of the fixing ring 142 can be provided with a longitudinal assembly flange 1422, and the outer periphery of the fixing ring 142 can be provided with a transverse assembly flange 1421, the longitudinal assembly flange 1422 is provided below the inner periphery of the transverse assembly flange 1421, the longitudinal assembly flange 1422 is connected to the side of the magnetic base 131, and the top of the transverse assembly flange 1421 is connected to the bottom of the inner periphery of the annular spring 141. In addition, the annular spring piece 141 can be provided with an outer ring body 1411, an inner ring body 1412 and a plurality of elastic connecting arms 1413, each elastic connecting arm 1413 connects the outer ring body 1411 and the inner ring body 1412, the top of the outer ring body 1411 is connected to the annular assembly groove 112 at the bottom of the speaker seat 11, the inner ring body 1412 is sleeved on the magnetic base 131, the top of the inner ring body 1412 is connected to the bottom of the annular joint flange 1311, and the bottom of the inner ring body 1412 is connected to the top of the transverse assembly flange 1421, so that the inner ring body 1412 is located between the annular joint flange 1311 and the transverse assembly flange 1421.

[0060] Based on the description of the above embodiments, the shock-absorbing speaker 1 of the present invention can make the outer ring body 1411 of the shock-absorbing component 14 firmly set in the annular assembly groove 112 of the speaker seat 11, and the inner ring body 1412 cooperates with the transverse assembly flange 1421 and the annular joint flange 1311 to be firmly positioned and clamped between the magnetic base 131 and the fixing ring 142 to improve the bonding strength, and at the same time, through each elastic connecting arm 1413, the speaker seat 11 and the magnetic return component 13 are not in direct contact, so as to improve the stability during buffering. Therefore, the shock-absorbing speaker 1 of the present invention can utilize the annular spring 141 to use each elastic connecting arm 1413 as a buffer between the speaker seat 11 and the magnetic return component 13 to absorb (consume) the kinetic energy generated when the speaker seat 11 vibrates, and reduce the vibration of the speaker seat 11 when the shock-absorbing speaker 1 is in operation, so as to enhance the stability of the shock-absorbing speaker 1 during operation, thereby achieving a better shock-absorbing effect, and avoiding the problems of distortion such as skewness and polarization of the diaphragm 121 and the voice coil 122 during high-power output.
