The two support legs of the U-shaped yoke are respectively wound with coils, enabling the two leg end faces to generate alternating magnetic poles under the control of circuit. The four permanent magnets are centrosymmetrically disposed about a rotatory central line, the first and the fourth magnet are of the same polarity, the second and the third magnet are of the same polarity; the first and the second magnet are of the opposite polarity, disposed corresponding to the first leg; the third and the fourth magnet are of the opposite polarity, disposed corresponding to the second leg. Under the control of circuit, the driving permanent magnets drive the second yoke and the rotary output component to reciprocatively rotate about the rotatory central line.

摘要： A technology for improving a device structure so that an external impact does not occur in a coil in order to solve a problem in that several attachments, such as coil, included in a linear vibration generator are separated or broken due to a small impact test or drop test on the linear vibration generator. The attachments, such as coil, included in the linear vibration generator can be prevented from being disconnected, separated or broken due to the execution of a small impact test and drop test on the linear vibration generator.

摘要： A linear vibration motor comprising a vibrator and a stator, wherein the vibrator comprises at least two permanent magnets disposed adjacent to each other and a magnetic yoke disposed between any two adjacent permanent magnets, and adjacent ends of the two adjacent permanent magnets have the same polarities; the stator comprises coils and magnetic cores disposed in the coils; magnetization directions of the permanent magnets are perpendicular to axis directions of the coils. The linear vibration motor enables the magnetic lines of flux of the permanent magnets to intensively pass through the coils by means of a repulsive force between two ends with same polarity of two permanent magnets so as to obtain a larger magnetic flux and a stronger vibration sensing effect.

摘要： Embodiments described herein may take the form of an electromagnetic actuator that produces a haptic output during operation. Generally, an electromagnetic coil is wrapped around a central magnet array. A shaft passes through the central magnet array, such that the central array may move along the shaft when the proper force is applied. When a current passes through the electromagnetic coil, the coil generates a magnetic field. The coil is stationary with respect to a housing of the actuator, while the central magnet array may move along the shaft within the housing. Thus, excitation of the coil exerts a force on the central magnet array, which moves in response to that force. The direction of the current through the coil determines the direction of the magnetic field and thus the motion of the central magnet array.

摘要： An electronic device may have an electrical component with a moving portion. The moving portion of the electrical component may include a moving mass and may include coils or other circuitry coupled to the moving mass. The moving mass may be supported within a support structure such as a housing structure. Springs may be coupled between walls in the housing structure and end portions of the moving mass. The coils or other circuitry on the moving mass may be coupled to flexible printed circuit cables. The flexible printed circuit cables may be coupled to the coils at the ends of the moving mass adjacent to the springs. The flexible printed circuit cables may have localized stiffeners that help prevent damage to metal traces in the cables during cable bending. The cables may have U-shapes or other suitable shapes.
