Abstract: The present invention provides a linear motor, wherein, a coil is fastened on a mass block that is suspended inside a housing, and a magnet is fastened on the housing and thus does not move during use. In the linear motor of the present invention, the design route that utilizes coil motion to drive mass block motion is different from the traditional route that utilizes magnet motion to drive mass block motion, thereby the traditional “moving-magnet type” is changed into “moving-coil type” of the present invention. When the linear motor provided by the present invention is used in a highly magnetic environment, even if magnetic shield plates for shielding external magnetic induction lines are glued on both outer sides of the housing, because the magnet is fixed stationary itself, no vertical deviation of the magnet due to influence of the shield plates like in the prior art occurs.

Abstract: The present invention provides a linear motor, wherein, a coil is fastened on a mass block that is suspended inside a housing, a first magnet and a second magnet that have opposite magnetic poles are symmetrically disposed at an upper side and at a lower side relative to the coil in the middle and positioned parallel to the centric plane of the coil, by arranging an upper magnetic steel and a lower magnetic steel at an upper side and at a lower side relative to the mass block in the middle and parallel to the mass block. In the linear motor of the present invention, the design route that utilizes coil motion to drive mass block motion is different from the traditional route that utilizes magnet motion to drive mass block motion.

Abstract: 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.
