Abstract

An embodiment of the invention provides a linear motor. The linear motor specifically comprises a vibrator, guide rails, a lubricating medium layer and a casing, wherein the vibrator comprises a mass block and a magnetic block, wherein a through hole is formed in the mass block, and the magnetic block is arranged in the through hole of the mass block; bulge parts are arranged on two opposite side walls of the mass block respectively; the guide rails are fixed on the inner side wall of the casing; groove parts matched with the bulge parts of the mass block are formed in the guide rails; the groove parts on the guide rails is in matched connection with the bulge parts on the mass block, and the mass block is fixed in the casing; the lubricating medium layer is arranged between each bulge part and the corresponding groove part. According to the linear motor, vibration noise produced after the vibrator polarizes and collides the casing can be avoided, besides, friction between the vibrator and the guide rails can be further reduced, noise generated by the vibrator in the vibration process can be reduced, and the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a linear motor and a mobile terminal. Background technique [0002] With the rapid development of communication technology, mobile terminals such as mobile phones and tablet computers are more and more widely used. On mobile terminals, it is more and more common to use vibration effects for incoming call prompts, message reminders, and application function progress feedback. The vibration effect of the mobile terminal is usually realized by the micro-vibration motor on the mobile terminal, and in the micro-vibration motor, the linear motor has been more and more widely used because of its fine vibration, low noise, strong vibration, and fast response time. . [0003] refer to figure 1 , showing a schematic diagram of the decomposition structure of an existing linear motor, such as figure 1 The shown linear motor may specifically include: a vibration space form...
