Fig. 1 is a schematic top view of a linear motor 100 shown in accordance with an exemplary embodiment, fig. 2 is a cross-sectional view a-a of the embodiment of fig. 1, and fig. 3 is a method schematic of the partial structure of fig. 2. As shown in fig. 1 to 3, the linear motor 100 may include a support 1, a rotation assembly 2, a vibrator assembly 3, and a driving assembly 4. The support 1 may include a hollow area 11, a side wall 12, an annular guide groove 13, and an annular track 14, where the hollow area 11 may be formed by the side wall 12, the annular guide groove 13 is disposed in the side wall 12, that is, the annular guide groove 13 may be formed by recessing the surface of the side wall 12 inwards, or the side wall 12 may be made into a hollow structure to form the annular guide groove 13. The annular track 14 may be formed by a surface of the sidewall 12 facing the hollow zone 11 being recessed inward, and the annular track 14 may penetrate to the annular guide groove 13 to communicate the annular guide groove 13 with the hollow zone 11. The rotating assembly 2 is arranged in the annular guide groove 13, and the rotating assembly 2 can rotate along the direction of the annular guide groove 13 under the driving of acting force. The vibrator assembly 3 may include a vibrator 31 and a spring 32, the vibrator 31 and the spring 32 are disposed in the hollow region 11, and one end of the spring 32 is connected to the vibrator 31 and the other end thereof may be connected to the rotating assembly 2 via the ring rail 14.

Further, the driving assembly 4 may be connected to the rotating assembly 2 to drive the rotating assembly 2 to rotate through the driving assembly 4, and since the rotating assembly 2 is connected to the spring 32 and the spring 32 is connected to the vibrator 31, the vibrator 31 may also be connected to a rotating shaft which can rotate around the depth direction of the hollow region 11 in order to meet the rotation requirement. Furthermore, for the purpose of adapting the vibrator 31 to be movable in a predetermined direction to generate vibration, the surface of the rotation shaft contacting the vibrator 31 may provide a planar area in which the vibrator 31 reciprocates in the predetermined direction.

Based on this, when the vibrator 31 vibrates in the preset direction under the action of the magnetic field, if the preset direction is the same as the stretching direction and the target direction of the spring 32, the spring 32 stretches under the action of the vibrator 32, and if the target direction is detected to be changed, the stretching direction of the spring 32 can be adjusted to coincide with the target direction, at this time, the vibrator 31 can still vibrate by the force in the preset direction, and in the vibration process of the vibrator 31, a component force is inevitably acted on the spring 32 to cause the spring 32 to stretch, so that the vibration frequency in the stretching direction of the spring 32 can be increased, and the vibration feeling of a user in the direction can be increased.

The target direction may be determined according to a touch operation of a user, for example, when a display screen of an electronic device in which the linear motor is configured by the user slides from top to bottom, the up-down direction may be used as the target direction. Of course, the user may slide from top to bottom only as an example, and the present disclosure is not limited thereto, and may be applied to other scenes, such as a game scene.

Wherein, this support 1 can adopt the magnetic conduction material to make, can avoid the magnetic field to expand outside support 1 on the one hand, and on the other hand can promote the directionality of magnetic field in hollow area 11, avoids magnetic field disorder. Further, in order to increase the vibration frequency of the linear motor 100 in the target direction to adapt to various application scenarios of the electronic device configuring the linear motor 100, as shown in fig. 1 and fig. 2, the linear motor 100 may further include a driving assembly 4, the driving assembly 4 may be connected to the connecting rod 21, the driving assembly 4 may be configured to drive the rotating assembly 2 to rotate along the annular guide slot 13, so as to synchronously drive the spring 32 to rotate, so as to change the stretching direction of the spring 32, and thus, by adjusting the stretching direction of the spring 32 to be the same as the target direction, the purpose of increasing the vibration frequency of the linear motor 100 in the target direction may be achieved, and the linear motor is adapted to more usage scenarios, and the usage experience of the user is improved. In order to realize the vibration of the spring 32, the vibrator assembly 3 may further include a rotation shaft connected to the vibrator 31, so as to avoid the spring 32 from being twisted, the vibrator 31 may be rotatably connected to the rotation shaft, or the rotation shaft may be rotatably connected to other seats, and the vibrator 31 is rigidly connected to the rotation shaft, which may be designed as required, and the disclosure does not limit this.

In an embodiment, still as shown in fig. 1-3, the rotating assembly 2 may include a connecting rod 21 and a rotating member 22 connected to the connecting rod 21, both the rotating member 22 and the connecting rod 21 may be disposed in the annular guide groove 13, and the spring 32 may be connected to the rotating member 22 through the annular rail 1, and the connecting rod 21 is connected to the driving assembly 4. Therefore, when the connecting rod 21 is rotated by the driving assembly 4, the rotating member 22 can be synchronously driven to rotate in the annular guide groove 13, and the extension direction of the spring 32 is changed. The rotating member 22 may include a ball or a slider, etc., which is not limited by the present disclosure.

Further, in order to achieve stability of the rotation of the rotating assembly 2 in the annular guide groove 13. As shown in fig. 3, the annular guide groove 13 may include a first guide groove 131, a second guide groove 132, and a communication slit 133 communicating the first guide groove 131 and the second guide groove 132. In order to improve the stability of the rotation of the rotating member 21 along the first guide slot 131, the connecting rod 21 may be located in the first guide slot 131, and the rotating member 22 may be located in the second guide slot 132, and the width of the through slot 133 may allow the connecting rod 21 to pass through and be smaller than the size of the rotating member 22, so that the bearing area surrounding the through slot 133 may contact the rotating member 22, thereby improving the stability of the rotation of the rotating assembly 2.

In one embodiment, the linear motor 100 may include a spring 32 and a rotating member connected to the spring 32, and in another embodiment, as shown in fig. 1 and 2, the rotating member 2 may include a plurality of rotating members 22, each rotating member 22 being connected to a spring 32.

Thereby, the vibrator 31 is connected to the springs 32 in the same direction, and when the springs 32 are rotated in the target direction, the vibration frequency of the vibrator 31 in the target direction can be further increased.

In another embodiment, as shown in fig. 4, the vibrator assembly 3 may include two sets of springs, and the springs 32 belonging to different sets are perpendicular to each other, i.e., the two sets of springs may be disposed in a substantially cross shape, so that the rotation angle of the rotation member 22 can be reduced, the wear can be reduced, and the service life can be prolonged during the adjustment to the target direction. Of course, as in the embodiment of fig. 1 and 4, only the vibrator assembly 3 includes one set of springs and two sets of springs for illustration, in fact, the vibrator assembly 3 may also include three or more sets of springs, and the present disclosure does not limit this.

In one case, as shown in fig. 6, the connecting rod 21 may include a connecting body 211, a first connecting bracket 212 and a second connecting bracket 213, the first and second connecting brackets 212 and 213 being connected to the same end of the connecting body 211, and the first and second connecting brackets 212 and 213 being connected to different rotating members 22 connected to the same set of springs. Wherein the first connecting bracket 212 may include a first portion 2121 and a second portion 2122, one end of the second portion 2122 is connected to the first portion 2121, and the other end is connected to the connecting body 211; similarly, the second connecting bracket 213 may include a first portion 2131 and a second bracket 2132, with one end of the second portion 2132 being connected to the first portion 2131 and the other end being connected to the connecting body 211.

Alternatively, as shown in fig. 7, the second portion 2122 of the first connecting bracket 212 may be connected to the connecting body 211 in an inclined manner, and the second portion 2132 of the second connecting bracket 213 may be connected to the connecting body 211 in an inclined manner, that is, the second portion 2122 of the first connecting bracket 212 is not parallel or perpendicular to the connecting body 211, and the second portion 2122 of the second connecting bracket 213 is not parallel or perpendicular to the connecting body 211.

That is, the first connecting bracket 212 and the connecting body 211 are not parallel or perpendicular, and the first connecting bracket 212 and the connecting body 211 form an included angle greater than 0 ° and less than 180 ° but not equal to 90 °; the second connecting bracket 213 and the connecting body 211 are not parallel or perpendicular, and the second connecting bracket 213 and the connecting body 211 form an included angle greater than 0 ° and less than 180 ° but not equal to 90 °.

For example, assuming that the electronic device is held by a user in a gun battle type game scene, if a bullet is shot towards the left side relative to the game user, the attention of the game user will be focused on the left side of the device, so the left side direction relative to the user can be determined as the target direction by the device, for example, the direction deviating from the left 45 ° when the user holds the device across the screen is the shot direction, then the direction deviating from the left 45 ° is the target direction, and thus the device can drive the driving assembly 4 to switch to the working state, so that the rotating assembly 2 rotates along the annular guide groove 13, and the telescopic direction of the group of springs 32 in the linear motor 100 can be adjusted to deviate from the left 45 °, so as to enhance the vibration sensation in the direction deviating from the left 45 ° and improve the user experience.
