FORCE FEEDBACK DEVICE AND ELECTRONIC DEVICE

WIPO Patent Application WO/2023/197893

A1

Disclosed in the present invention are a force feedback device and an electronic device. The force feedback device comprises a casing, an operation part and a linear driving assembly, the operation part being slidably arranged on the casing in the moving direction of the operation part, the linear driving assembly comprising a stator fixedly arranged in the casing and a mover slidably arranged in the casing in the moving direction of the operation part, and the mover being connected to the operation part. One of the mover and the stator is set to be an ultra-thin pancake coil, and the other is set as a magnet structure. The pancake coil is located in a magnetic field generated by the magnet structure, and interactive electromagnetic forces generated between the pancake coil and the magnet structure are fed back to a finger of a user, so that a flat, small-size and ultrathin design can be achieved while the overall structure of the linear driving assembly meets a force feedback effect, thus solving the problem of an existing single force feedback device occupying a lot of space and being difficult to miniaturize.
