摘要： A magnetic balance structure includes a counter weight, a positioning element, a first positioning magnet, a shell and a shaft. The positioning element is set on the counter weight or the shell and the positioning element is set with the first positioning magnet face-to-face. The shaft is set on the shell. The interaction of the positioning element with the first positioning magnet causes the counter weight to do reciprocating motion along the shaft. Furthermore, A magnetic balance linear vibration motor includes a shell internally provided with a stator, a rotor and a shaft. The stator includes a drive coil driving the rotor cutting its magnetic lines of force, generate driving force, and driving the rotor to do reciprocating linear motion along the shaft. The positioning element and the first positioning magnet are respectively set on the rotor or the shell.

摘要： A vibrator-mounted holder is attached to a casing of a vibration generator which moves a vibrator to generate a vibration when used. The vibrator-mounted holder includes a vibrator, a vibrator retention unit retaining the vibrator, a fixing unit fixed to a casing, and an arm. The vibrator includes a magnet having a plate shape parallel to a horizontal surface and a yoke arranged on the magnet. The arm connects the fixing unit to the vibrator retention unit, and supports the vibrator retention unit in a manner that the vibrator retention unit is displaceable with respect to the fixing unit. The yoke has a projecting portion which is projected downward and fixed to the vibrator retention unit. The arm is connected to a portion, at which the projecting portion is arranged, within the vibrator retention units.

摘要： A lens driving module for holding and moving a lens is provided, including a lens holder having an accommodating space, a driving coil, a plurality of first magnetic members having a longitudinal structure, a virtual plane, and a plurality of second magnetic members, wherein the lens is disposed in the accommodating space. The lens holder is disposed between the first magnetic members and between the second magnetic members. The driving coil is disposed on the lens holder and surrounds the accommodating space. The virtual plane is perpendicular to a longitudinal axis of the longitudinal structure. The projections of the driving coil and the first magnetic members on the virtual plane along the longitudinal axis of the longitudinal structure overlap each other. When a first current flows through the driving coil, the lens holder moves relative to the first and second magnetic members along a first direction.

摘要： A vibration generating device that can make a relatively heavy vibration member produce sufficient vibration. A vibration generating device has: a vibration member; multiple actuators that are connected to the vibration member; and a stationary element that supports the vibration member via the multiple actuators. Each of the multiple actuators comprises: a supporting body to which the vibration member is fixed; a movable element; a first elastic member that is connected to the supporting body and the movable element; and a magnetic drive circuit (a first magnetic drive circuit and a second magnetic drive circuit) that makes the movable element move linearly back and forth relative to the supporting body. The multiple actuators are supported by the stationary element via a second elastic member. The first elastic member and the second elastic member comprise a gelatinous silicone gel or the like.
