A manipulating device comprising: a rocker, a supporting member a magnetic assembly and a coil assembly, wherein the rocker is rotatable around the supporting member; the coil assembly is disposed opposite to the rocker, the magnetic assembly is disposed on one end of the rocker adjacent to the coil assembly; the magnetic assembly () comprising a central magnet () and at least one side magnets. By providing the magnetic assembly on the one end of the rocker adjacent to the coil assembly (), the power for rotating the rocker is adjusted by interaction force between the magnetic assembly and the coil assembly, and the interaction force between the magnetic assembly and the coil assembly can be further adjusted by adjusting the magnitude of the current of the coil assembly.

Manipulating device

The present disclosure provides an exciter and an electronic product. The exciter comprises: a magnetic circuit assembly comprising a first housing and a magnet, and the magnet is connected to the first housing; a coil assembly comprising a second housing and a coil, and the coil is disposed in a magnetic field formed by the magnet, wherein the coil assembly is configured to be capable of generating a vibration relative to the magnetic circuit assembly, the coil is formed by winding a wire having a polygonal cross section. According to the present disclosure, the coil wire has a polygonal cross section, so that an interval between the wires can be reduced in the wound coil, the number of turns of the coil is increased in the same space, the effective length of the coil is increased, and the driving force generated from the coil is increased.

Exciter and electronic product

A manipulating device comprising: a rocker, a supporting member a magnetic assembly and a coil assembly, wherein the rocker is rotatable around the supporting member; the coil assembly is formed to have an arc shape, an inner surface of the arc shape faces the rocker, the magnetic assembly is disposed on one end of the rocker adjacent to the coil assembly. According to the technical solution, by providing the magnetic assembly on the one end of the rocker adjacent to the coil assembly, the power for rotating the rocker is adjusted by interaction force between the magnetic assembly and the arc-shaped coil assembly, and the interaction force between the magnetic assembly and the coil assembly can be further adjusted by adjusting the magnitude of the current of the coil assembly.

Disclosed are a vibration sound device for an electronic product and the electronic product. The vibration sound device comprises a first housing, a magnetic assembly, a coil assembly and a second housing. The first housing includes a cavity and is opened at one side thereof. An interaction force is generated between the magnetic assembly in the first housing and the coil assembly on the second housing to drive the vibration sound device to vibrate so as to generate a sound. According to the present disclosure, the magnetic assembly and the coil assembly are configured in a sandwiched structure, so that the overall height of the vibration sound device is reduced, and thus space utilization of the electronic device is improved.
