A fast-response horizontal vibration micro motor that includes a housing, a cover plate, a vibration assembly and coils. The cover plate is installed on the housing; the vibration assembly is suspended in the installation space; the coils are located at positions a certain distance above the vibration assembly; the vibration assembly 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 vibration; the vibration assembly includes a vibration block, and the vibration block is provided with at least three installation through holes and permanent magnets 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. |
