Problems solved by technology
However, when the vibration intensity of the vibrator is high, the attraction force between the magnets is often not enough to overcome the inertia of the vibrator, so that the vibration of the vibrator in the vertical direction cannot be prevented.
At the same time, the setting of long bar magnets will also make the magnetic environment in the linear motor more complicated, increasing the design difficulty of the linear motor

The invention discloses a linear motor and an electronic device. The linear motor comprises a shell, an alternating magnetic field generating device, a vibrator, a first guide rod assembly and a second guide rod assembly, wherein the first guide rod assembly and the second guide rod assembly extend in the first direction. The alternating magnetic field generating device is connected to the shell.The vibrator comprises a magnet and a mass block. The magnet is connected with the mass block. A containing groove is formed in the mass block, and the alternating magnetic field generating device isarranged in the containing groove and can drive the vibrator to move in the first direction. The first guide rod assembly and the second guide rod assembly are arranged on the two opposite sides of the mass block in the first direction respectively and are in sliding connection with the shell respectively. Therefore, the driving force generated in the linear motor is larger, and the efficiency andthe vibration capability of the linear motor under the same volume are improved.
Description
technical field [0001] The present application relates to the field of electronic equipment, in particular to a linear motor and an electronic equipment. Background technique [0002] Compared with the rotary motor in the related art, it has faster starting and braking speed, more delicate vibration and less noise. The application is more and more extensive. [0003] However, if the transverse linear motor generates a vibration component in the vertical direction, it will generate relatively large noise, and at the same time affect the life of the transverse linear motor. In order to maintain the lateral linear motor to vibrate only in the lateral direction as much as possible, a method in the related art is to provide a slide rail-groove connection between the vibrator and the housing of the linear motor. But the rail-groove connection is less stable and prone to friction noise. At the same time, the slide rail-groove connection occupies a relatively large area, which wi...
