Magnetic force pressure-sensitive ear-hanging earphone

Abstract

The application provides a magnetic force pressure-sensitive ear-hanging earphone, which comprises an ear hook, an earphone body, a first magnetic part and a second magnetic part, the ear hook is provided with an open slot, the earphone body is rotationally connected to the ear hook, the first magnetic part is fixed to the ear hook, the second magnetic part is fixed to the earphone body and is oppositely arranged with the first magnetic part at intervals, wherein the earphone body is in an initial position when being located in the open slot, and the magnetic field of the first magnetic part and the second magnetic part interacts to generate a restoring force for driving the earphone body to rotate towards the initial position. In the process of wearing the earphone, the earphone body is tightly clamped on the tragus of the ear under the magnetic field interaction of the first magnetic part and the second magnetic part, thereby a second fixed point is generated, the earphone is not easy to move or fall off, and the use experience is improved; meanwhile, the earphone body can be tightly combined with the concha cavity of the ear, which is beneficial to preventing sound leakage and improving the sound effect.

Claims
