Title:
LINEAR MOTOR APPARATUS AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/227678
Kind Code:
A1
Abstract:
A linear motor apparatus. Structures such as an air cylinder (20) having unidirectional vent holes (221, 222), a mass block (30) having an L-shaped extension portion (32), an air pipe (40), and electromagnets (50, 60) are provided, so that automatic inflation and suction, and vibration functions of the linear motor apparatus can be achieved. An inflatable bag (70) is further connected to the air pipe, so that the process of automatic inflation and suction can be transformed into unidirectional movement of the inflatable bag so as to provide power for a movable component (90) as a power source of the movable component. The structure of a linear motor is improved, so that the linear motor has the function of providing vibration and can also serve as a power source of a movable component, and therefore, the space of a terminal device can be saved, thereby facilitating achieving miniaturization and light weight of the terminal device.
