Title:
LINEAR VIBRATION MOTOR
Document Type and Number:
WIPO Patent Application WO/2017/088367
Kind Code:
A1
Abstract:
A linear vibration motor comprising an oscillator and a stator arranged parallel to the oscillator. The oscillator comprises a counterweight block (5) and an oscillating block embeddedly fixed within the counterweight block. The oscillating block comprises at least two adjacently arranged magnets (81, 82, and 83) and magnetic yokes (91 and 92) arranged between the adjacently arranged magnets. The polarities of adjacent extremities of the two adjacently arranged magnets are identical. The magnets are an arbitrary combination of permanent magnets and/or electromagnets. The stator comprises stator coils (61 and 62) arranged on a side or either of upper and lower sides of the oscillator and magnetic cores (71 and 72) arranged in the stator coils. The axis direction of the stator coils is perpendicular to the magnetization direction of the magnets of the oscillating block. The oscillating block of the linear vibration motor is constituted by utilizing the arbitrary combination of permanent magnets and electromagnets, thus expanding ways in which the linear vibration motor is implemented, and increasing the flexibility of a production process.
