[0055] To fully understand the purpose, features, and effects of the present invention, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings:
[0056] Please refer to Figures 1 to 7 As shown in the figure, the first embodiment of the present invention provides a vibration-damping loudspeaker 1, which includes: a sound-generating unit 11, a magnetic return assembly 12, two fixing members 13, and four elastic members 14. The sound-generating unit 11 and the magnetic return assembly 12 may be rectangular or square.
[0057] The sound-generating unit 11 includes a speaker mount 111, a diaphragm 112 and a voice coil 113. The speaker mount 111 may be a rectangular frame. The diaphragm 112 is located on the top of the speaker mount 111, and the voice coil 113 is connected to the bottom of the diaphragm 112.
[0058] The magnetic return assembly 12 includes a main magnetic plate 121 and a magnetic guiding unit 122. The main magnetic plate 121 may have a U-shaped cross-section. The magnetic guiding unit 122 is disposed on the top surface of the bottom of the main magnetic plate 121. The voice coil 113 is movably disposed outside the magnetic guiding unit 122 and between the main magnetic plate 121 and the magnetic guiding unit 122. The magnetic guiding unit 122 may have a magnet 1221 and a magnetic guiding plate 1222 stacked on top of each other.
[0059] Each fixing member 13 may be trapezoidal and respectively located on the two short sides of the main magnetic plate 121, and each fixing member 13 may be made of plastic.
[0060] Each elastic element 14 is respectively disposed between the two short sides of the bottom of the horn seat 111 and the left and right sides of each fixing element 13. Two of the elastic elements 14 are directly connected to one short side of the bottom of the horn seat 111 and one fixing element 13. The other two elastic elements 14 are directly connected to the other short side of the horn seat 111 and the other fixing element 13. In this way, each fixing element 13 and each elastic element 14 can form a simple vibration damping and isolation structure for the magnetic return assembly 12 at the bottom of the horn seat 111. In addition, no components need to pass through between the elastic elements 14, the short side of the bottom of the horn seat 111, and the fixing element 13 on one short side of the bottom of the horn seat 111, and the other short side of the bottom of the horn seat 111 is the same. Therefore, the vibration damping and isolation structure of the present invention has a simpler structure compared to the prior art. In the prior art, to increase the strength of the elastic structure, it is necessary to deliberately insert elastic iron parts through the elastic structure to improve the supporting force of the elastic structure on the magnetic return assembly. Since the two elastic parts 14, the short side of the bottom of the horn seat 111, and the fixing part 13 of the present invention are directly connected by abutment, the structural strength and the supporting force on the magnetic return assembly 12 can be improved without any inserting components between the two elastic parts 14, the short side of the bottom of the horn seat 111, and the fixing part 13. Furthermore, in one embodiment of the present invention, each elastic part 14 is symmetrically arranged on the two short sides of the bottom of the horn seat 111 and symmetrically arranged on the left and right sides of each fixing part 13, and the material of each elastic part 14 can be silicone.
[0061] When the vibration-damping speaker 1 of the present invention is assembled, each fixing member 13 and each elastic member 14 can be symmetrically arranged on the two short sides of the bottom of the speaker base 111. The left and right sides of each elastic member 14 are respectively connected to the bottom of the speaker base 111 and the left and right sides of each fixing member 13. Then, each fixing member 13 is respectively connected to the two short sides of the main magnetic plate 121, so that the sound-generating unit 11 and the magnetic return assembly 12 are less likely to be misaligned, thereby enabling the sound-generating unit 11 and the magnetic return assembly 12 to be quickly and easily assembled to improve the manufacturing yield. When the vibration-damping speaker 1 of the present invention is used, it can be combined with a speaker box (not shown). After the voice coil 113 of the sound-generating unit 11 receives the externally input electronic signal, the magnetic energy is provided by the cooperation of the main magnetic plate 121 and the magnetic guiding unit 122 of the magnetic return assembly 12. The voice coil 113, in conjunction with the electromagnetic action of the magnetic return assembly 12, drives the diaphragm 112 to operate, thereby enabling the vibration-damping speaker 1 to produce sound.
[0062] When the vibration-damping speaker 1 of the present invention operates as described above, due to the arrangement of each fixing member 13 and each elastic member 14, the speaker base 111 of the sound-generating unit 11 and the magnetic return assembly 12 are not in direct contact. Therefore, the mutual cooperation of each fixing member 13 and each elastic member 14 can be used as a buffer between the speaker base 111 and the magnetic return assembly 12 to absorb (dissipate) the kinetic energy generated when the sound-generating unit 11 vibrates and prevent the kinetic energy generated when the magnetic return assembly 12 vibrates from being transmitted back. Thus, the vibration-damping speaker 1 achieves the effect of vibration reduction and isolation when it operates, thereby avoiding discomfort for the user when using electronic devices. In addition, by using each fixing member 13 and each elastic member 14 as a buffer between the speaker base 111 and the magnetic return assembly 12, the vibration frequency of the magnetic return assembly 12 can be similar to but opposite in phase with the vibration frequency of the speaker base 111, thus further achieving the effect of vibration reduction.
[0063] Furthermore, since the fixing members 13 and the elastic members 14 do not need to cover the speaker base 111 and the main magnetic plate 121, and since the fixing members 13 and the elastic members 14 can be made of plastic and silicone respectively as needed, the bottom of the fixing members 13 and the elastic members 14 can be flat, and the elastic coefficient can be easily adjusted so that the vibration frequency of the magnetic return assembly 12 is similar to but opposite in phase with the vibration frequency of the speaker base 111, and interference with the operation of the voice coil 113 is avoided. Moreover, since the bottom surface of the main magnetic plate 121 does not need to be filled with silicone to increase the clamping force on the main magnetic plate 121, the height of the vibration-damping speaker 1 of the present invention can be further reduced. Although the reduction in height is minimal, for such ultra-thin speakers with a height of less than 4mm, even a reduction of 0.1mm can bring significant benefits.
[0064] In addition to the above embodiments, in one embodiment of the present invention, the left and right inner edges of each short side of the bottom of the speaker base 111 may be provided with a connecting portion 114, and one side of each elastic member 14 may be provided with a first fitting portion 141, which can be fitted into the connecting portion 114. Furthermore, the left and right sides of each fixing member 13 may be provided with a mating portion 131, and the other side of each elastic member 14 may be provided with a second fitting portion 142, which can be fitted into the mating portion 131. Thus, the vibration-damping speaker 1 of the present invention can effectively increase the bonding strength between each fixing member 13, each elastic member 14 and the speaker base 111 by utilizing the cooperation of each connecting portion 114 with each first fitting portion 141, and each mating portion 131 with each second fitting portion 142, thereby making it less likely for the three to detach, achieving the effect of quick and easy assembly to improve manufacturing yield.
[0065] In addition to the above embodiments, in one embodiment of the present invention, the speaker base 111, each fixing member 13, and each elastic member 14 can be integrally injection molded. Each elastic member 14 integrates each fixing member 13 with the speaker base 111, but the fixing members 13 are not directly connected to the speaker base 111. Therefore, when each fixing member 13 is assembled with the main magnetic plate 121 of the magnetic return assembly 12, the magnetic return assembly 12 can be suspended on the speaker base 111 through the provision of each elastic member 14, and further, the elastic members 14 generate shock absorption and vibration isolation effects.
[0066] In addition to the above embodiments, in one embodiment of the present invention, a vent hole 115 may be provided between the two short sides of the bottom of the speaker base 111 and each fixing member 13. In an embodiment of the present invention, the two short sides of the bottom of the magnetic return assembly 12 may be symmetrically fixed to the four corners of the bottom of the speaker base 111 (visually in the shape of an I) by four elastic members 14, so that the magnetic return assembly 12 and the two short sides of the bottom of the speaker base 111 respectively form a vent hole 115, thereby increasing the air permeability of the damped speaker 1, which helps the damped speaker 1 to expel internal gas during operation, thereby improving bass sound quality and reducing distortion.
[0067] In addition to the above embodiments, in one embodiment of the present invention, each fixing member 13 may have a mounting portion 132 (e.g., a groove) on one side, and the two short sides of the main magnetic plate 121 may each have an extension segment 123, with each extension segment 123 disposed in each mounting portion 132. Thus, the vibration-damping speaker 1 of the present invention can expand the contact area by designing that each extension segment 123 and each mounting portion 132 have the same contour, allowing each extension segment 123 to adhere and bond with each mounting portion 132, resulting in a fast assembly speed.
[0068] Please refer to Figures 8 to 13As shown in the figure, in addition to the above embodiments, in the second embodiment of the present invention, each extension segment 123 may be provided with a positioning hole 124, and one side of each fixing member 13 may be provided with a positioning protrusion 133, with each positioning hole 124 connected to each positioning protrusion 133. In this way, the vibration-damping speaker 1 of the present invention can effectively increase the bonding strength between each fixing member 13 and the main magnetic plate 121, making them less prone to separation, thereby achieving the effect of quick and easy assembly to improve manufacturing yield.
[0069] Please refer to Figures 14 to 17 As shown in the figure, in addition to the above embodiments, in one embodiment of the present invention, a connecting section 143 may be provided between two of the elastic members 14, and each connecting section 143 is directly abutted and connected between each fixing member 13 and the short side of the bottom of the speaker base 111. In this way, the vibration-damping speaker 1 of the present invention can increase the area of each elastic member 14 and enhance the supporting force of each elastic member 14 on the magnetic return assembly 12. Furthermore, by using the connecting sections 143 to fill the space between each fixing member 13 and the speaker base 111, the overall vibration damping and isolation effect can be improved through the increased area of each elastic member 14. Additionally, in an embodiment of the present invention, each vent 115 may be located on the wall of the two short sides of the speaker base 111.
[0070] Please refer to Figure 18 As shown in the figure, in addition to the above embodiments, in one embodiment of the present invention, the cross-section of the elastic member 14 can be "I" shaped, or other equivalent shapes, such as a cross shape (that is, the two sides of the elastic member 14 can be inserted into the speaker seat 111 and the fixing member 13). This design helps to strengthen the connection strength between the elastic member 14, the speaker seat 111, and the fixing member 13, so as to avoid the risk of the elastic member 14 falling off when the speaker seat 111 or the magnetic return assembly 12 is displaced due to excessive vertical vibration. Additionally, please refer to... Figure 11 and Figure 17 As shown in the figure, in addition to the above embodiments, in one embodiment of the present invention, the orientation of the elastic member 14 may be parallel to the tapering direction of the extension segment 123. This maximizes the area of the extension segment 123 to avoid sacrificing magnetic force, and also avoids the risk of the elastic member 14 detaching due to excessive horizontal displacement between the speaker base 111 and the magnetic return assembly 12 during vibration. Furthermore, since both the speaker base 111 and the fixing member 13 can be injection molded from plastic, the present invention can also provide through holes in the speaker base 111 and / or the fixing member 13 to allow silicone to be injected into the through holes during injection to strengthen the bond strength between the elastic member 14 and the speaker base 111 and the fixing member 13.
