摘要： An electric linear actuator includes a fixed block, an output movable block, a counter movable block, a projecting side coupling member, a retracting side coupling member, a block coupling member, and an output functional member. The output movable block and the counter movable block are configured to be reciprocated in the movable direction in opposite phases by electromagnetic force acting between the fixed block and the output and counter movable blocks. The projecting side coupling member is coupled to the output movable block and the counter movable block. The retracting side coupling member is coupled to the output movable block and the counter movable block. The projecting side coupling member and the retracting side coupling member have different shapes.

摘要： A zoom lens comprises a focus driving mechanism and a zoom driving mechanism and corresponding lens groups. The zoom driving mechanism is sleeved outside the focus driving mechanism. The focus driving mechanism is a voice coil motor and comprises a focus stator assembly (7a1) and a focus rotor assembly (7a2) that are connected by means of an elastic connection member (7a3). One of a focus stator sleeve (7a11) in the focus stator assembly and a focus rotor sleeve (7a21) in the focus rotor assembly is a permanent magnet sleeve, and the other of the focus stator sleeve (7a11) and the focus rotor sleeve (7a21) is a non-magnet sleeve, and the assembly to which the non-magnet sleeve belongs further comprises a preliminary magnetic member (7a22) and a driving coil (7a23). Due to the magnetic force pre-existing between the preliminary magnetic member and the permanent magnet sleeve, the elastic connection member is in a force balanced state without electrification, so that a smaller electromagnetic force is required for driving the elastic connection member, and accordingly the driving current and power consumption are reduced. Moreover, because the zoom driving mechanism is sleeved outside the focus driving mechanism, a large aperture can be easily realized, and installation and implementation are easier.

摘要： An electromagnetic actuator includes a coil that is selectively energizable by an electric current. The electromagnetic actuator further includes an armature having a outwardly extending prong. The armature is movably disposed with respect to the coil such that when the coil is energized with the electric current, the armature moves in relation to the coil and disposing thereby the prong on a first side of the coil. A flux gatherer is provided to be disposed around a second side of the coil, thereby channeling magnetic flux emanating from the coil back into the armature and prong.

摘要： A double resonance vibration motor includes a housing, vibration parts in the housing, a coil fixed in the housing, and elastic connectors to support elastically the vibration part. The vibration parts include a mass block, a first magnet group and a second magnet group installed in the mass block. The coil is opposite to the first magnetic group and the second magnetic group. The driving force generated by the first magnetic group and the coil makes the vibration motor vibrate along the first direction. The driving force of the second magnet group and the coil makes the vibration motor vibrate along the second direction. The first direction and the second direction are intersected. Two different directions have respectively one resonance frequency. Two different resonant frequencies can vibrate alone or at the same time, to realize the control in different vibration directions.
