DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENT

The present disclosure will hereinafter be described in detail with reference to an exemplary embodiment. To make the technical problems to be solved, technical solutions and beneficial effects of the present disclosure more apparent, the present disclosure is described in further detail together with the figure and the embodiment. It should be understood the specific embodiment described hereby is only to explain the disclosure, not intended to limit the disclosure.

Please refer toFIGS.1-5together, a vibration device100provided by an exemplary embodiment of the present disclosure includes a housing1with a receiving space10and a vibration unit2received in the receiving space10.

The vibration unit2includes a stator21fixed to the housing1, a vibrator22suspended in the receiving space10, and an elastic support member23configured to suspend the vibrator22in the receiving space10. In one embodiment, the stator21includes a coil211fixed to the housing1, and the vibrator22includes a magnet221. The coil211and the magnet221interact to drive the vibrator22to vibrate relative to the stator21for generating haptic feedback. It can be understood that the coil211and the magnet221can interchange. Moreover, the vibrator22further includes a battery222suspended by the elastic support member23. The battery222is served as mass to vibrate for generating desired haptic feedback. Generally, the weight of the battery is larger than the weight of a normal mass in the vibration motor. In this manner, no extra mass component is needed, thus effectively improving the space utilization rate of the vibration device and reducing cost.

The elastic support member23includes a bottom plate231fixed to the battery222, a first fixation portion232bending and extending from an edge of the bottom plate231, a first elastic portion233extending from one end of the first fixation portion232, a second elastic portion234extending from the other end of the first fixation portion232, and a first connection portion235connecting the first elastic portion233and the second elastic portion234; the first connection portion235is arranged opposite the first fixation portion232; the first fixation portion232, the first elastic portion233, the second elastic portion234, and the first connection portion235surrounds the battery222, the first connection portion235is fixed to the housing1for suspending the elastic support member23in the receiving house10.

Specifically, the bottom plate231is in a rectangle shape, the first fixation portion232and the first connection portion235extend along a long axis of the bottom plate231, respectively; the first elastic portion233and the second elastic portion234extend along a short axis of the bottom plate231, respectively. In order to drive the vibrator22to vibrate back and forth by the deforming the first elastic portion233and the second elastic portion234, the first elastic portion233, the second elastic portion234, and the first connection portion235are all spaced apart from the bottom plate231. In addition, the elastic support member23further includes a second connection portion236connecting the bottom plate231and the first fixation portion232; a length of the second connection portion236along the long axis of the bottom plate231is smaller than a length of the bottom plate231along its long axis.

Furthermore, the first elastic portion233includes a first elastic arm2331connecting with the first fixation portion232, a second elastic arm2332connecting with the first connection portion235, and a connection arm2333connecting the first elastic arm2331and the second elastic arm2332; the elastic support member23further includes a second fixation portion237bending and extending from the connection arm2333to be fixed to the housing1. Thus, only the second elastic portion234, the first elastic arm2331, and the second elastic arm2332deforms during vibration. The second connection portion236and the connection arm2333do not deform.

In one embodiment, the battery222includes a side surface2221spaced apart from the first elastic portion233, the magnet221is attached to the side surface2221, the coil211is fixed to a side of the connection arm2333facing the magnet221, the coil211and the magnet221are arranged at an interval. In order to improve the drive force generated by the coil211and the magnet221to enhance the haptic feedback of the vibrator unit2, the magnet221extends into the coil211along a vibration direction of the vibrator22. It can be understood that the coil211is annular with a hollow structure.

In this embodiment, the vibration device100is a stylus. In other embodiments, the vibration device can be other portable mobile terminals with battery, such as watch.

Compared with the related art, in the vibration device of the present disclosure, a battery is served as mass to vibrate generating desired haptic feedback, which effectively enhances the vibration feedback by increasing the mass weight. Furthermore, no extra mass component is needed, thus effectively improving the space utilization rate of the vibration device and reducing cost.

It is to be understood, however, that even though numerous characteristics and advantages of the present exemplary embodiments have been set forth in the foregoing description, together with details of the structures and functions of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms where the appended claims are expressed.
