[0060] 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, as follows:

[0061] Please refer to Figures 1 to 7 As shown in the figure, the present invention provides a multi-drive type shock-absorbing speaker 1, which can be a rectangular speaker and includes: a speaker seat 11, a sound-generating component 12, two magnetic return components 13 and a shock-absorbing component 14. In addition, the multi-drive type shock-absorbing speaker 1 of the present invention can also include three magnetic return components 13 or four magnetic return components 13, etc.

[0062] The speaker seat 11 may be rectangular and have two adjacent setting portions 111. In addition, the speaker seat 11 may also have three adjacent setting portions 111 or four adjacent setting portions 111.

[0063] The sound-generating component 12 includes a diaphragm 121 and two voice coils 122. The diaphragm 121 may be elliptical (or racetrack-shaped) and disposed on the top of the speaker seat 11. Each voice coil 122 may be elliptical (or racetrack-shaped) and disposed on each setting portion 111 and connected to the diaphragm 121. In addition, the sound-generating component 12 may also include three voice coils 122 or four voice coils 122, etc.

[0064] Each magnetic return assembly 13 includes a magnetic base 131 and a magnetic unit 132. Each magnetic base 131 can be elliptical (or racetrack-shaped), and each magnetic unit 132 can be elliptical (or racetrack-shaped) and is disposed on each magnetic base 131. Each voice coil 122 is movably disposed in a magnetic gap between each magnetic unit 132 and each magnetic base 131. Each magnetic base 131 can be a U-shaped iron. Each 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, each magnetic unit 132 can be a staggered stacked combination of a magnetic plate 1321 and two magnets 1322.

[0065] The shock absorbing assembly 14 connects the speaker seat 11 and each magnetic return assembly 13. The shock absorbing assembly 14 includes a spring 141 and two fixing rings 142. The spring 141 is provided with two limiting ring bodies 1411. The two sides of the spring 141 are respectively connected to the two sides of the speaker seat 11. Each limiting ring body 1411 can be elliptical (or runway-shaped) and connected to each magnetic seat 131. Each fixing ring 142 can be elliptical (or runway-shaped) and connected to each magnetic seat 1 31 and each limiting ring 1411, so that each magnetic return component 13 does not directly contact the speaker seat 11, wherein the spring 141 can be a metal spring, 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 spring 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. In addition, the shock absorbing component 14 can also include three fixing rings 142 or four fixing rings 142, etc., and the spring 141 can also be provided with three limiting rings 1411 or four limiting rings 1411, etc.

[0066] When the multi-drive shock-absorbing loudspeaker 1 is used, it can be combined with a sound box (not shown). After the lead wire 1221 of each voice coil 122 receives the external electronic signal input by the circuit board 112 at the center of the speaker seat 11, the magnetic force provided by the magnetic base 131 and the magnetic unit 132 of each magnetic return component 13 allows the electromagnetic action of each voice coil 122 to cooperate with each magnetic return component 13 to drive the diaphragm 121 to move, thereby making the multi-drive shock-absorbing loudspeaker 1 produce sound.

[0067] When the multi-drive shock-absorbing loudspeaker 1 performs the above-mentioned operation, since the limiting rings 1411 of the spring sheet 141 provided in the shock-absorbing component 14 prevent the speaker seat 11 from directly contacting the magnetic return components 13, the spring sheet 141 can be used as a buffer between the speaker seat 11 and the magnetic return component 13, so that the vibration frequency of the magnetic return component 13 can be close to the vibration frequency of the speaker seat 11 but with an opposite phase, and the vibration of the speaker seat 11 can be reduced when the multi-drive shock-absorbing loudspeaker 1 is in operation, so as to improve the stability of the multi-drive shock-absorbing loudspeaker 1 during operation, thereby exerting a better shock-absorbing effect. In addition, when the sound-generating component 12 is actuated, the actuation of each voice coil 122 on the diaphragm 121 will also generate a reaction force on each magnetic return component 13 and the shock-absorbing component 14. The multi-drive type shock-absorbing speaker 1 of the present invention can adjust the vibration frequency of the reaction force to be close to the vibration frequency of the sound-generating component 12 but opposite in phase, thereby generating a force that offsets the action of the sound-generating component 12 to achieve the purpose of shock absorption. Furthermore, the spring 141 can be used as a buffer between the speaker seat 11 and each magnetic return component 13 to prevent the kinetic energy generated by the vibration of each magnetic return component 13 from being transmitted back, and achieve the effect of shock absorption and isolation when the multi-drive type shock-absorbing speaker 1 is in operation, thereby avoiding discomfort to the user when using the electronic device.

[0068] Based on the description of the above embodiments, the multi-drive shock-absorbing loudspeaker of the present invention can utilize the shock-absorbing component 14 to increase the power bearing capacity and exert a better shock-absorbing effect to avoid the distortion problems such as skewing and polarization of the sound-generating component 12 when outputting high power.

[0069] In addition to the above embodiments, in one embodiment of the present invention, an avoidance portion 1412 may be provided between each limiting ring body 1411. In this way, the multi-drive type shock-absorbing speaker 1 of the present invention can have the circuit board 112 disposed on the speaker seat 11 and located between the two voice coils 122, and the lead wires 1221 of each voice coil 122 are respectively electrically connected to the circuit board 112, so as to complete the series or parallel connection of each voice coil 122, and the avoidance portion 1412 corresponds to the circuit board 112, so as to utilize the avoidance portion 1412 to avoid the electrical connection area between the circuit board 112 and each lead wire 1221, so that the circuit board 112 and each lead wire 1221 have a better electrical connection effect.

[0070] In addition to the above embodiments, in one embodiment of the present invention, the bottoms of the two short sides of the speaker seat 11 may be provided with a plurality of assembly parts 113, and the two sides of the spring sheet 141 are respectively connected to each assembly part 113. In this way, the multi-drive type shock absorbing speaker 1 of the present invention can make the spring sheet 141 stably arranged on the assembly part 113 of the speaker seat 11, so as to increase the stability of the shock absorbing assembly 14 when used as a buffer.

[0071] In addition to the above embodiments, in one embodiment of the present invention, the spring sheet 141 may include a plurality of docking portions 1413, a plurality of elastic arms 1414 and a plurality of connecting arms 1415, the two ends of each elastic arm 1414 are respectively connected to each docking portion 1413 and each limiting ring body 1411, the two ends of each connecting arm 1415 are respectively connected to each limiting ring body 1411, and each docking portion 1413 is connected to each assembly portion 113. In this way, the multi-drive type shock absorbing speaker 1 of the present invention can make each limiting ring body 1411 of the shock absorbing assembly 14 firmly disposed on the assembly portion 113 of the speaker seat 11 by each docking portion 1413, and each limiting ring body 1411 cooperates with each fixing ring 142 to be firmly positioned and connected to each magnetic conductive seat 131 to improve the bonding strength, and at the same time, through each elastic arm 1414 and each connecting arm 1415, the speaker seat 11 and the magnetic return assembly 13 are not in direct contact, so as to improve the stability during buffering. In addition, the spring 141 of the multi-drive shock-absorbing speaker 1 of the present invention can be a metal spring, so the weight of each magnetic return component 13 and the elastic coefficient of each elastic arm 1414 can determine a vibration frequency, and the reaction force can make the phase opposite, so by adjusting the mass of each magnetic return component 13 and the elastic coefficient of each elastic arm 1414, a frequency that offsets the vibration of the sound-generating component 12 can be obtained.

[0072] In addition to the above embodiments, in one embodiment of the present invention, the inner periphery of each fixing ring 142 may be provided with a transverse assembly flange 1421, and the outer periphery of each fixing ring 142 may be provided with a longitudinal assembly flange 1422, each longitudinal assembly flange 1422 is arranged below the outer periphery of each transverse assembly flange 1421, each transverse assembly flange 1421 is connected to the top of each magnetic conductive seat 131, and each longitudinal assembly flange 1422 is connected to the side of each magnetic conductive seat 131 and the top of each limiting ring body 1411. In this way, the multi-drive type shock absorbing speaker 1 of the present invention can connect the assembly parts 113 at the bottom of the speaker seat 11 with the docking parts 1413 during assembly, and the limiting ring bodies 1411 can be sleeved on the magnetic seats 131 and the top of each limiting ring body 1411 can be connected to the bottom of each longitudinal assembly flange 1422, and each transverse assembly flange 1421 can be connected to the top of each magnetic seat 131. In this way, the multi-drive type shock absorbing speaker 1 of the present invention can make the docking parts 1413 of the shock absorbing component 14 firmly set on the assembly parts 113 of the speaker seat 11, and each limiting ring body 1411 can cooperate with each fixing ring 142 to be firmly positioned and connected to each magnetic seat 131 to improve the bonding strength, and at the same time, each elastic arm 1414 can be used to prevent the speaker seat 11 from directly contacting with each magnetic return component 13 to improve the stability during buffering. In addition, the spring 141 of the multi-drive shock-absorbing speaker 1 of the present invention can be a metal spring, so the weight of each magnetic return component 13 and the elastic coefficient of each elastic arm 1414 can determine a vibration frequency, and the reaction force can make the phase opposite, so by adjusting the mass of each magnetic return component 13 and the elastic coefficient of each elastic arm 1414, a frequency that offsets the vibration of the sound-generating component 12 can be obtained.

[0073] In addition to the above embodiments, in one embodiment of the present invention, the number of the elastic arms 1414 on both sides of the spring sheet 141 can be two (but the number is not limited to two). In this way, the multi-drive type shock absorbing speaker 1 of the present invention can make each elastic arm 1414 have a better buffering effect, and can achieve a better balance when vibrating, thereby producing the maximum vibration reduction effect.

[0074] In addition to the above embodiments, in one embodiment of the present invention, the bottoms of the two long sides of the speaker seat 11 may be provided with at least one step surface 114, and the two sides of the circuit board 112 and the connecting arms 1415 correspond to the step surfaces 114. In this way, the multi-drive type shock absorbing speaker 1 of the present invention can use the step surfaces 114 to keep the connecting arms 1415 and the speaker seat 11 at an appropriate longitudinal distance h1, so as to prevent the spring sheet 141 from causing the connecting arms 1415 to hit the speaker seat 11 when vibrating.

[0075] In addition to the above embodiments, in one embodiment of the present invention, each connecting arm 1415 and the circuit board 112 can also maintain an appropriate lateral distance h2 to prevent the lead 1221 of each voice coil 122 from touching each connecting arm 1415, so that the circuit board 112 and each lead 1221 have a better electrical connection effect.

[0076] Please refer to Figures 8 to 14 As shown in the figure, in addition to the above-mentioned embodiment, in one embodiment of the present invention, a notch 1416 is respectively provided at the center of the corresponding side of each limiting ring body 1411 (i.e., at the position of the avoidance portion 1412). In this way, the multi-drive type shock absorbing speaker 1 of the present invention can make each limiting ring body 1411 present as a broken ring to prevent each limiting ring body 1411 from being too close to the speaker seat 11 and the circuit board 112.

[0077] In addition to the above embodiments, in one embodiment of the present invention, an elastic member 1417 is provided between each connecting arm 1415 and the speaker seat 11, wherein each elastic member 1417 can be selected from damping materials such as silicone, sponge, or glue that is soft after curing as required. In this way, the multi-drive type shock-absorbing speaker 1 of the present invention can utilize the arrangement of each elastic member 1417 to prevent each connecting arm 1415 from hitting the speaker seat 11 and making abnormal sounds, thereby reducing the vibration of the speaker seat 11 and improving the stability of the multi-drive type shock-absorbing speaker 1 during operation, thereby exerting a better shock-absorbing effect, thereby avoiding the problem of distortion such as skewness and polarization of the diaphragm 121 and the voice coil 122 when outputting high power.

In this way, each limiting ring body 1411 can cooperate with each fixing ring 142 to be firmly positioned and connected to each magnetic base 131 to improve the bonding strength, and at the same time, each elastic arm 1414 can prevent the speaker base 11 from directly contacting each magnetic return assembly 13 to improve the stability during buffering. In addition, the spring 141 of the multi-drive shock-absorbing speaker 1 of the present invention can be a metal spring, so the weight of each magnetic return component 13 and the elastic coefficient of each elastic arm 1414 can determine a vibration frequency, and the reaction force can make the phase opposite, so by adjusting the mass of each magnetic return component 13 and the elastic coefficient of each elastic arm 1414, a frequency that offsets the vibration of the sound-generating component 12 can be obtained.
