Abstract: A dual diamagnetic linear resonant actuator includes a magnetic induction element, a magnet set and a coil. The magnet set comprises four magnets. The N pole of first magnet, the N pole of second magnet, the S pole of third magnet and the S pole of fourth magnet press respectively against the first, second, third and fourth sides of the magnet induction element. The coil surrounds the magnetic induction element and the third and fourth magnets, and maintains a distance from the first end and the second end of the magnetic induction element, and from the N pole of the third and fourth magnets. As such, the first and second magnets compress magnetic field lines, and the third and fourth magnets strengthen the magnetic force, and guide the magnetic field lines towards the coil to accomplish concentration of magnetic field density and to avoid divergence of the magnetic field lines.

Abstract: A linear vibration actuator is provided, comprising a movable structure, a coil and an elastic suspension system. The elastic suspension system comprises a first and a second elastic sheets, and the first and second elastic sheet respectively comprising a first and a second fixed portions, a first and a second suspension portions, and a first and a second engaging portions. Both first and second suspension portions comprise a bend with an angle greater than 90°. The elastic suspension system enables the simple harmonic motion of the movable structure approximating a parallel motion to improve vibration effect without increasing current outputted to the coil, so as to reduce temperature and power consumption of the present invention. As a result, the present invention is able to provide superior vibration effect to portable electronic product and solve the overheating and power consumption problems.

Abstract: A resonant vibration actuator includes a casing, a mover, a plurality of electromagnet sets, two elastic suspensions, and a connecting circuit. The casing is provided with connection terminals for connection on the outside of the casing. The mover has a mover frame, a plurality of permanent magnet units, and two magnetic backs. The permanent magnet units and the magnetic backs are arranged in the mover frame and the electromagnet sets are arranged between the permanent magnet units. Elastic suspensions are connected to the casing and the mover respectively through two connection portions at both ends. The connecting circuit is used to connect the electromagnet sets and the connection terminals outside the casing. By energizing the electromagnet sets, the electromagnet sets act on the permanent magnet units to make the mover move relatively in the casing to generate vibration.
