FAST-RESPONSE HORIZONTAL VIBRATION MICRO MOTOR

摘要

A fast-response horizontal vibration micro motor comprises a housing (1), a cover plate (2), a vibration assembly (4) and coils (5). The cover plate is installed on the housing in a covering manner so as to create an installation space by the housing and the cover plate; the vibration assembly is suspended in the installation space through positioning of elastic supporting members (3) respectively located on the two opposite sidewalls of the housing; the coils are located at positions a certain distance above the vibration assembly; the vibration assembly, under the impact of a magnetic field force, can perform reciprocating vibration in a direction substantially parallel to the bottom surface of the housing, and also enables the two elastic supporting members located on the two opposite sidewalls to be correspondingly stretched and compressed during the vibration process; the vibration assembly comprises a vibration block (41), and the vibration block is provided with at least three installation through holes (42) and permanent magnets (43) installed in the installation through holes. The arrangement of the three permanent magnets increases the response speed of the motor, and the arrangement of the two serially-connected coils also increases the response speed of the motor.
