Title:

LINEAR VIBRATION MOTOR

Document Type and Number:

WIPO Patent Application WO/2022/062149

Kind Code:

A1

Abstract:

A linear vibration motor, comprising a housing (100), a vibrator structure (200), and a stator structure (300). The vibrator structure (200) is movably provided in a mounting cavity defined by the housing (100), and the vibrator structure (200) comprises a pair of first magnetic steels (210) that are oppositely arranged and spaced apart from each other and a pair of second magnetic steels (220) that are oppositely arranged and spaced apart from each other; each first magnetic steel (210) comprises a first section (213) and second sections (214) extending from two ends of the first section (213), a mounting position (212) is formed between the two opposite second sections (214), and the second magnetic steel (220) is located at the mounting position (212); the pair of the first magnetic steels (210) and the pair of the second magnetic steels (220) enclose a surrounding region (230), and the polarity of the first magnetic steels (210) facing the surrounding region (230) is different from the polarity of the second magnetic steels (220) facing the surrounding region (230). The linear vibration motor has a strong vibration sensation; moreover, the existing space of the vibrator structure can be fully used, and under the condition of a certain space, the purpose of improving the vibration sensation is achieved.
