[0034] In the technical scheme of the present application, the coil assembly 2 comprises the first coil 21 and the second coil 22, and the magnet structure 3 comprises the first magnet 31, when the first coil 21 is energized, the coil assembly 2 and the first magnet 31 generate a force interacting in the first direction, and when the second coil 22 is energized, the coil assembly 2 and the first magnet 31 generate a force interacting in the second direction, based on the two directions of force that can be generated, the first magnet 31 or the coil assembly 2 is arranged as the vibration member in the present application, the shell 1 comprises the outer shell 11 and the inner shell 13, the inner shell 13 can be movable in the first direction in the outer shell 11 through the first elastic member 12, and the vibration member can be movable in the second direction in the inner shell 13 through the second elastic member 4. In this way, when the first coil 21 is energized, the vibration member can drive the inner shell 13 to move in the first direction in the outer shell 11, and when the second coil 22 is energized, the vibration member can independently move in the second direction in the inner shell 13, so that the vibration of the vibration device 100 in two directions is clearly distinguished, and better user experience can be provided.

[0035] Specifically, the coil assembly 2 further comprises a core 23; the first coil 21 is arranged around the core 23, and the second coil 22 is arranged around the first coil 21 and the core 23. In order to gather the magnetic field generated by the first coil 21 and the second coil 22 when energized, so as to increase the driving force of the interaction between the first magnet 31, thereby improving the vibration intensity of the vibration device 100 and improving the user experience, the coil assembly 2 further comprises the core 23, and the first coil 21 and the second coil 22 are both arranged around the core 23.

[0036] In addition, the first elastic member 12 comprises two first fixed parts 121 and a first elastic connecting part 122, the two first fixed parts 121 are connected to the inner shell 13 and the outer shell 11 respectively, and the first elastic connecting part 122 is arranged in a bent manner with the first fixed part 121 to connect the two first fixed parts 121. The specific structure of the first elastic member 12 can be various, including but not limited to springs, elastic sheets, etc., which can realize the elastic reset function, and is not limited herein. In this embodiment, the first elastic member 12 is provided in the form of an elastic sheet structure, which is simple in structure, stable in performance and good in use effect. Specifically, the first elastic member 12 comprises two first fixed parts 121, which are connected to the inner shell 13 and the outer shell 11 respectively, so as to ensure the stability of the connection of the first elastic member 12. The first elastic connecting part 122 is elastically stretched in the first direction, so as to realize the elastic movement of the inner shell 13 in the outer shell 11 in the first direction and meet the use requirement.

[0037] In addition, the magnet structure 3 further comprises a counterweight 32, and the first magnet 31 is mounted on the counterweight 32; the second elastic member 4 connects the counterweight 32 and the inner shell 13. On the one hand, the second elastic member 4 is connected to the counterweight 32 and the inner shell 13 to enhance the vibration effect of the vibration device 100, and on the other hand, the second elastic member 4 is connected to the counterweight 32 and the inner shell 13 to mount and fix the magnet structure 3. When the second coil 22 is energized, the first magnet 31 drives the counterweight 32 to move in the inner shell 13 in the second direction, and when the first coil 21 is energized, the first magnet 31 drives the counterweight 32 and the inner shell 13 to move in the outer shell 11 in the first direction, thereby meeting the use requirement.

[0038] Specifically, one side of the inner shell 13 in the second direction is connected with the counterweight 32 through the second elastic piece 4, and the other side in the second direction is provided with the first damping piece 123 between the counterweight 32. When the second elastic piece 4 drives the counterweight 32 to vibrate in the second direction, resonance may occur, affecting the vibration experience, so in this embodiment, the first damping piece 123 and the second elastic piece 4 are respectively arranged between the two sides of the counterweight 32 in the second direction and the inner shell 13, so that the first damping piece 123 is compressed when the counterweight 32 moves in the second direction, thereby playing a buffering effect and further suppressing resonance, thereby improving the vibration effect of the vibration device 100.

[0039] Specifically, the counterweight 32 is provided with a receiving groove 321, and the first damping piece 123 is received in the receiving groove 321. On the one hand, it is convenient to install and place the first damping piece 123, and on the other hand, it avoids the first damping piece 123 from being separated from the counterweight 32 during use to affect the normal function. In this embodiment, the receiving groove 321 is provided on the counterweight 32 to accommodate the first damping piece 123, thereby meeting the above requirements.

[0040] In addition, the second elastic piece 4 is also provided in a leaf structure in the same way as the first elastic piece 12, which is simple in structure, stable in performance and good in use effect.

The two second fixed parts 41 are respectively arranged on the inner shell 13 and the counterweight 32, and the second elastic connecting part 42 is arranged in a bent manner with the second fixed parts 41 to connect the two second fixed parts 41. The two second fixed parts 41 are respectively connected with the inner shell 13 and the counterweight 32 to ensure the stability of the connection of the second elastic piece 4. The second elastic connecting part 42 is elastically stretched and contracted in the second direction, so that the counterweight 32 can be elastically moved in the second direction in the inner shell 13, thereby meeting the use requirements.

[0041] In addition, the second damping piece 43 is arranged at the interval between the outer shell 11 and the inner shell 13 in the first direction. Similarly, when the first elastic piece 12 drives the inner shell 13 to vibrate in the first direction, resonance may occur, affecting the vibration experience, so in this embodiment, one second damping piece 43 is arranged between the two sides of the inner shell 13 in the first direction and the outer shell 11, so that the second damping piece 43 is compressed when the inner shell 13 moves in the first direction, thereby playing a buffering effect and further suppressing resonance, thereby improving the vibration effect of the vibration device 100.

[0042] In addition, the first magnet 31 is arranged on both sides of the coil assembly 2 in the third direction, and the opposite side magnetic poles of the two first magnets 31 are the same. The opposite side magnetic poles of the two first magnets 31 are the same, so that the two first magnets 31 can generate driving forces in the same direction when the coil assembly 2 is energized, thereby improving the vibration intensity of the vibration device 100 and improving the user experience.

[0043] In addition, the magnet structure 3 further comprises a second magnet 33 arranged on both sides of the first magnet 31 in the first direction, and the magnetic pole of the second magnet 33 close to the first magnet 31 is the same as the magnetic pole of the first magnet 31 close to the coil assembly 2. The magnetic field of the second magnet 33 can diverge along the magnetic field of the first magnet 31, so that the magnetic field of the first magnet 31 and the magnetic field of the second magnet 33 after fusion is stronger than the magnetic field strength of the first magnet 31 itself, thereby improving the magnetic driving force after the coil assembly 2 is energized, thereby improving the vibration intensity of the vibration device 100 and improving the vibration experience.

[0044] Specifically, each first magnet 31 is provided with a second magnet 33 on both sides in the first direction. The second magnet 33 can be arranged around the circumference of the first magnet 31, and the specific arrangement position and the arrangement number can not be limited, as long as the above-mentioned function of enhancing the magnetic field of the first magnet 31 can be realized. However, generally, the magnet is a square structure, so in this application, one second magnet 33 is arranged on both sides of the first magnet 31 in the first direction to form an elongated magnet group, which is convenient for structural arrangement.

[0045] In addition, the magnet structure 3 further comprises a magnetic conductive plate 34, and the first magnet 31 and the second magnet 33 on the same side of the coil assembly 2 are fixed to the magnetic conductive plate 34. On the one hand, the above-mentioned elongated magnet group is fixed to avoid the magnetic force between the first magnet 31 and the second magnet 33 affecting the original structural arrangement, thereby avoiding affecting the function of the vibration device 100. On the other hand, the magnetic field of the above-mentioned elongated magnet group is further focused and enhanced to improve the vibration performance of the vibration device 100. The first magnet 31 and the second magnet 33 are fixed by the magnetic conductive plate 34, which is simple in structure and good in effect.

[0046] The above-mentioned is only an exemplary embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation made by using the content of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
