Abstract

The present application discloses a giant magnetostrictive motor, comprising a first giant magnetostrictive rod and a second giant magnetostrictive rod, wherein the first giant magnetostrictive rod is connected to the second giant magnetostrictive rod, The surfaces of the first giant magnetostrictive rod and the second giant magnetostrictive rod are both wound with coils; wherein, when the coils on the surface of the first giant magnetostrictive rod are energized, the first giant magnetostrictive rod The giant magnetostrictive rod is axially deformed; when the coil on the surface of the second giant magnetostrictive rod is energized, the second giant magnetostrictive rod is radially deformed. The present application can solve the problems of single vibration direction and weak vibration amount of motors currently configured in electronic equipment, thus resulting in poor vibration effect.

Description

technical field [0001] The application belongs to the technical field of motors, and in particular relates to a giant magnetostrictive motor. Background technique [0002] With the continuous progress and development of electronic communication technology, smart phones have become an irreplaceable necessity, and the use of vibration motors in smart phones has also attracted widespread attention. The vibration function of the mobile phone can be used to prompt incoming calls or messages, and the user can also feel the vibration of the button while touching the screen, thereby bringing a good tactile feedback experience to the user. [0003] At present, vibration motors in mobile phones are mainly divided into two categories: rotor motors and linear motors. The rotor motor is mainly composed of a DC motor and an eccentric wheel; the linear motor is mainly composed of a stator, a mover, and a slide rail. Among them, the response speed of the rotor motor is slow, there is no d...
