Abstract

The embodiment of the invention provides a headset and belongs to the field of electronic equipment. The headset comprises a shell and a net cover which are arranged in a split mode. A sound outlet is formed in the shell. The net cover covers the sound outlet. The net cover is made of magnetic shielding materials. A loudspeaker assembly is arranged in the shell and provided with a magnetic circuit unit. According to the headset, the net cover and the shell are arranged in the split mode, and the net cover covers the sound outlet of the shell; due to the fact that the net cover is made of the magnetic shielding materials, the outward-radiation magnetic flux of the magnetic circuit unit of the loudspeaker assembly can be reduced, the magnetic flux on the periphery of the net cover is greatly reduced, the attraction force of the magnetic circuit unit to external ferromagnetic substances is effectively weakened, the phenomenon that the ferromagnetic substances are attracted into a vibration film of the loudspeaker assembly through the net cover and the sound outlet is avoided, and it is ensured that the sound quality effect of the headset is not affected and the service life of the headset is prolonged.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to an earphone. Background technique [0002] Existing earphones generally include a plastic shell and a plastic net cover, the shell and the net cover are integrally formed, a horn assembly is arranged inside the shell, and a magnetic circuit unit is arranged on the horn assembly. During the use of the earphone, because the magnetic circuit unit in the housing has a certain magnetic attraction force, small ferromagnetic substances (such as iron filings, nickel alloy powder, etc.) are easily sucked into the housing through the mesh cover; and these iron Magnetic substances are also easily adsorbed on the diaphragm of the speaker assembly, which affects the sound quality and service life of the earphones, causing problems such as low volume and noise in the earphones. Contents of the invention [0003] In order to overcome the problem in the prior art that ferromagnetic substan...
