Background Technology

[0002] In general, the magnetic return assembly of a loudspeaker is usually fixedly assembled to the speaker mount. Since there is no buffer design between the speaker mount and the magnetic return assembly, the vibration of the loudspeaker is directly transmitted to the housing of the electronic device on which the loudspeaker is installed when the loudspeaker is operating, causing discomfort to the user when using the electronic device.

[0003] Therefore, how to invent a shock-absorbing rectangular magnetic return assembly to achieve the effects of shock absorption and vibration isolation, so as to avoid discomfort for users when using electronic devices, is what this invention aims to actively disclose. Summary of the Invention

[0056] 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:

[0057] Please refer to Figures 1 to 4 First embodiment and Figures 5 to 8 In the second embodiment, as shown in the figure, the present invention provides a shock-absorbing rectangular magnetic return assembly, which includes: a rectangular magnetic return assembly 10 and a shock-absorbing structure 20. The rectangular magnetic return assembly 10 can also be a square magnetic return assembly with the long side equal to the short side. The shock-absorbing structure 20 can be a rectangle, a rectangular-like shape, a square shape, or a square-like shape corresponding to the shape of the rectangular magnetic return assembly 10.

[0058] The rectangular magnetic return assembly 10 includes a main magnetic plate 11, a magnetic guiding unit 12, a shock-absorbing structure connecting part 13, and at least one shock-absorbing groove 14. The magnetic guiding unit 12 is disposed on the top of the main magnetic plate 11, and the shock-absorbing structure connecting part 13 and the shock-absorbing groove 14 are disposed on the bottom of the main magnetic plate 11. The shock-absorbing structure connecting part 13 and the shock-absorbing groove 14 can be integrally formed on the bottom of the main magnetic plate 11. The shock-absorbing groove 14 is located outside the shock-absorbing structure connecting part 13, and the shock-absorbing structure connecting part 13 protrudes from the bottom of the main magnetic plate 11 beyond the shock-absorbing groove 14.

[0059] The shock-absorbing structure 20 can be integrally formed and includes an annular horn seat docking portion 21, a magnetic return component docking portion 22, a first elastic connection module 23, and a second elastic connection module 24. The magnetic return component docking portion 22 is located inside the annular horn seat docking portion 21. The first elastic connection module 23 and the second elastic connection module 24 are connected between the two long sides and two short sides of the annular horn seat docking portion 21 and the two long sides and two short sides of the magnetic return component docking portion 22. The magnetic return component docking portion 22 is connected to the shock-absorbing structure connecting portion 13. The magnetic return component docking portion 22 can be bonded or welded to the shock-absorbing structure connecting portion 13. The first elastic connection module 23 and the second elastic connection module 24 are disposed in the shock-absorbing groove 14. In this invention, the shock-absorbing structure 20 can be made of stainless steel.

[0060] When the shock-absorbing rectangular magnetic return assembly of the present invention is used, a loudspeaker 1 can be formed by combining the annular horn seat docking portion 21 of the shock-absorbing structure 20 with the horn seat 31 of a sound-generating unit 30. The annular horn seat docking portion 21 may be provided with multiple assembly portions 211 (e.g., assembly holes) to be bonded to the docking portions 311 (e.g., docking protrusions) of the horn seat 31, so that there is no misalignment between the sound-generating unit 30 and the rectangular magnetic return assembly 10, thereby enabling the sound-generating unit 30 and the rectangular magnetic return assembly 10 to be quickly and easily assembled to improve the manufacturing yield. When the loudspeaker 1 is used, it can be combined with a speaker box (not shown). After the voice coil of the sound-generating unit 30 receives the externally input electronic signal, the magnetic energy is provided by the cooperation of the main magnetic plate 11 and the magnetic guiding unit 12 of the rectangular magnetic return assembly 10. The voice coil, in conjunction with the electromagnetic action of the rectangular magnetic return assembly 10, drives the diaphragm 32 to actuate, thereby making the loudspeaker 1 produce sound.

[0061] When the speaker 1 operates as described above, due to the arrangement of the rectangular magnetic return assembly 10 and the damping structure 20, the speaker base 31 of the sound-generating unit 30 and the rectangular magnetic return assembly 10 are not in direct contact. Therefore, the damping structure 20 can be used as a buffer between the speaker base 31 and the rectangular magnetic return assembly 10, so that the vibration frequency of the rectangular magnetic return assembly 10 can be similar to the vibration frequency of the speaker base 31 but opposite in phase, so as to further achieve the effect of vibration reduction and thus avoid discomfort when the user uses the electronic device.

[0062] Please refer to Figures 1 to 4In the first embodiment, as shown in the figure, there can be two damping grooves 14. The two damping grooves 14 are respectively disposed on the two short sides of the main magnetic plate 11. The first elastic connection module 23 can be disposed in one of the damping grooves 14, and the second elastic connection module 24 can be disposed in the other damping groove 14. In addition, the two damping grooves 14 can be U-shaped, and a portion of each damping groove 14 can extend to the two long sides of the main magnetic plate 11. In this way, the damping structure 20 can be symmetrically disposed on the two short sides of the rectangular magnetic return assembly 10, so that the speaker 1 uses the damping structure 20 as a buffer between the speaker base 31 and the rectangular magnetic return assembly 10 to absorb (dissipate) the kinetic energy generated when the speaker base 31 vibrates and to prevent the kinetic energy generated when the rectangular magnetic return assembly 10 vibrates from being transmitted back, thereby achieving the effect of damping and vibration isolation when the speaker 1 is operating, and thus avoiding discomfort for the user when using electronic devices.

[0063] Please refer to Figures 5 to 8 In the second embodiment, as shown in the figure, the number of damping grooves 14 can be one. The damping groove 14 can be annular and is arranged around the outside of the damping structure connection part 13. The first elastic connection module 23 and the second elastic connection module 24 are disposed in the damping groove 14. The first elastic connection module 23 is disposed on one short side and two long sides of the main magnetic plate 11, and the second elastic connection module 24 is disposed on the other short side and two long sides of the main magnetic plate 11. Thus, the damping structure 20 can be symmetrically arranged on the two short sides and two long sides of the rectangular magnetic return assembly 10, so that the speaker 1 can use the damping structure 20 as a buffer between the speaker base 31 and the rectangular magnetic return assembly 10 to absorb (dissipate) the kinetic energy generated when the speaker base 31 vibrates and prevent the kinetic energy generated when the rectangular magnetic return assembly 10 vibrates from being transmitted back, thereby achieving the effect of damping and vibration isolation when the speaker 1 is operating, and thus avoiding discomfort for the user when using electronic devices.

[0064] Please refer to Figures 1 to 4 First embodiment and Figures 5 to 8In a second embodiment, as shown in the figure, in addition to the above embodiments, in one embodiment of the present invention, the first elastic connection module 23 may include at least one first short side elastic arm 231 (two first short side elastic arms 231 are shown as an example in this embodiment), and the second elastic connection module 24 may include at least one second short side elastic arm 241 (two second short side elastic arms 241 are shown as an example in this embodiment). The first short side elastic arm 231 and the second short side elastic arm 241 are symmetrical. The first short side elastic arm 231 is connected between one short side of the annular horn seat docking portion 21 and one short side of the magnetic return assembly docking portion 22, and the second short side elastic arm 241 is connected between the other short side of the annular horn seat docking portion 21 and the other short side of the magnetic return assembly docking portion 22. Alternatively, the first elastic connection module 23 may include at least one first long-side elastic arm 232 (two first long-side elastic arms 232 are shown as an example in this embodiment), and the second elastic connection module 24 may include at least one second long-side elastic arm 242 (two second long-side elastic arms 242 are shown as an example in this embodiment). The first long-side elastic arm 232 and the second long-side elastic arm 242 are symmetrical. The first long-side elastic arm 232 is connected between one long side of the annular horn seat docking portion 21 and one long side of the magnetic return assembly docking portion 22, and the second long-side elastic arm 242 is connected between the other long side of the annular horn seat docking portion 21 and the other long side of the magnetic return assembly docking portion 22. Additionally, please refer to... Figures 1 to 4 In the first embodiment, as shown in the figure, the number of first long-side elastic arms 232 can be two, and the number of second long-side elastic arms 242 can be two. The two first long-side elastic arms 232 can be adjacent to a short side of the magnetic return assembly docking portion 22, and the two second long-side elastic arms 242 can be adjacent to a short side of the magnetic return assembly docking portion 22. This allows the two first short-side elastic arms 231 and the two first long-side elastic arms 232 of the first elastic connection module 23 to be disposed in one of the damping grooves 14, and the two second short-side elastic arms 241 and the two second long-side elastic arms 242 of the second elastic connection module 24 to be disposed in the other damping groove 14. Furthermore, please refer to... Figures 5 to 8 In the second embodiment, as shown in the figure, the number of the first long side elastic arms 232 can be two, and the number of the second long side elastic arms 242 can be two. The two first long side elastic arms 232 and the two second long side elastic arms 242 can be located near the middle of the magnetic return assembly docking part 22, so that the two first short side elastic arms 231 and the two first long side elastic arms 232 of the first elastic connection module 23 and the plurality of second short side elastic arms 241 and the two second long side elastic arms 242 of the second elastic connection module 24 can be evenly distributed in the shock absorption groove 14.

[0065] Thus, the damping structure 20 can be symmetrically arranged on the long and short sides of the rectangular magnetic return assembly 10 by the first short side spring arm 231, the first long side spring arm 232, the second short side spring arm 241, and the second long side spring arm 242, so that the first short side spring arm 231, the first long side spring arm 232, the second short side spring arm 241, and the second long side spring arm 242 can support the rectangular magnetic return assembly 10 from the X-axis and Y-axis directions, thereby buffering the vibration of the rectangular magnetic return assembly 10. This allows the speaker 1 to use the damping structure 20 as a buffer between the speaker base 31 and the rectangular magnetic return assembly 10, and to make the vibration frequency of the rectangular magnetic return assembly 10 similar to but opposite in phase with the vibration frequency of the speaker base 31, thereby further achieving the damping effect and avoiding discomfort for the user when using electronic devices.

[0066] Please refer to Figures 1 to 4 First embodiment and Figures 5 to 8 In a second embodiment, as shown in the figure, in addition to the above embodiment, in one embodiment of the present invention, the number of the first short-side elastic arms 231 can be two, and the number of the second short-side elastic arms 241 can be two. The two first short-side elastic arms 231 can each be U-shaped and have a first short-side bent portion 233. The two first short-side bent portions 233 can be arranged in opposite directions so that the notches of the two first short-side bent portions 233 face each other. The two second short-side elastic arms 241 can each be U-shaped and have a second short-side bent portion 243. The two second short-side bent portions 243 can be arranged in opposite directions so that the notches of the two second short-side bent portions 243 face each other. Furthermore, as... Figure 4 and Figure 8 As shown, the two first short-side bends 233 extend beyond the two long sides of the magnetic return assembly docking portion 22, and the two second short-side bends 243 extend beyond the two long sides of the magnetic return assembly docking portion 22. This increases the length of the two first short-side spring arms 231 and the two second short-side spring arms 241, improving their elasticity and allowing adjustment of their resonant frequencies to enhance vibration damping.

[0067] Please refer to Figures 1 to 4 First embodiment and Figures 5 to 8In a second embodiment, as shown in the figure, in addition to the above embodiment, in one embodiment of the present invention, the number of the first long-side elastic arms 232 can be two, and the number of the second long-side elastic arms 242 can be two. The two first long-side elastic arms 232 can each be U-shaped and have a first long-side bent portion 234. The two first long-side bent portions 234 can be arranged in the same direction so that the notches of the two first long-side bent portions 234 face outwards (or inwards). The two second long-side elastic arms 242 can each be U-shaped and have a second long-side bent portion 244. The two second long-side bent portions 244 can be arranged in the same direction so that the notches of the two second long-side bent portions 244 face outwards (or inwards). Furthermore, as... Figure 4 and Figure 8 As shown, each of the first long-side spring arms 232 can be U-shaped and have a first long-side bend 234. The ratio of the length A of the side of the first long-side bend 234 parallel to the long side of the annular horn seat docking portion 21 to the length B of the side of the first long-side bend 234 parallel to the long side of the magnetic return assembly docking portion 22 can be 1.6:1 to 2.4:1. Each of the second long-side spring arms 242 can be U-shaped and have a second long-side bend 244. The ratio of the length A of the side of the second long-side bend 244 parallel to the long side of the annular horn seat docking portion 21 to the length B of the side of the first long-side bend 244 parallel to the long side of the magnetic return assembly docking portion 22 can be 1.6:1 to 2.4:1. Therefore, the elasticity of the two first long-side spring arms 232 and the two second long-side spring arms 242 can be adjusted, thereby adjusting the resonant frequency of the two first long-side spring arms 232 and the two second long-side spring arms 242 to increase the vibration damping effect.

[0068] Please refer to Figure 4 and Figure 8 As shown in the figure, in addition to the above embodiments, one embodiment of the present invention may also include multiple damping units 40. These multiple damping units 40 may be disposed between the annular speaker mount docking portion 21 and the main magnetic plate 11, or between the assembly portion 211 of the annular speaker mount docking portion 21 and the docking portion 311 of the speaker mount 31. The multiple damping units 40 are symmetrical to each other. Each damping unit 40 may be a block, and the material of each damping unit 40 may be silicone, foam, low-viscosity soft adhesive, or other damping materials. In this way, the multiple damping units 40 can act as a buffer between the speaker mount 31 and the rectangular magnetic return assembly 10, absorbing (consuming) the kinetic energy generated when the speaker mount 31 vibrates and preventing the kinetic energy generated when the rectangular magnetic return assembly 10 vibrates from being transmitted back, thereby achieving vibration reduction and isolation effects when the speaker 1 is operating, and thus avoiding discomfort for the user when using electronic devices.

However, those skilled in the art should understand that these embodiments are for illustrative purposes only and should not be construed as limiting the scope of the invention. It should be noted that all variations and substitutions equivalent to these embodiments should be considered to be within the scope of the present invention.
