Title:
VIBRATOR STRUCTURE AND LINEAR MOTOR USING VIBRATOR STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2020/211046
Kind Code:
A1
Abstract:
Provided in the present invention are a vibrator structure and a linear motor using the vibrator structure. The linear motor comprises a vibrator structure (100), wherein the vibrator structure (100) comprises a mass block (110) having a containing cavity (111), a pole core (120) contained in the containing cavity (111), and magnetic steel (130) fixed on the mass block (110), and the mass block (110) covers the pole core (120) in an injection molding mode when being formed so as to enable the pole core (120) to be embedded in the mass block (110). The mass block (110) covering the pole core (120) in an injection molding mode when being formed enables the assembly process of the vibrator structure (100) to be simple, the cooperation between the mass block (110), the pole core (120) and the magnetic steel (130) can be compact, limited space can be effectively used, and the vibrator structure (100) can be provided with the mass block (110) of a greater weight in the limited space so as to improve the feel of vibration.
