EARPHONES AND MOBILE TERMINAL
Document Type and Number:
WIPO Patent Application WO/2022/042747
Kind Code:
A1
Abstract:
The present application provides earphones and a mobile terminal. Each earphone comprises: a housing and a loudspeaker assembly. The interior of the housing comprises a front cavity and a rear cavity separated by the loudspeaker assembly. The front cavity is located on the side of a sound output direction of the loudspeaker assembly, and the rear cavity is located on the side opposite to the sound output direction of the loudspeaker assembly. One or more sound guide channels are provided on the housing. Each sound guide channel is provided on the side wall of the housing. Each sound guide channel is used for enabling, when the earphones are normally worn, air in the ear canal of a user to be communicated with air outside the ear canal in the case that air in the front cavity is not communicated with air in the rear cavity. When the solution above is adopted, the environment in the ear canal is communicated with the environment outside the ear canal by means of the sound guide channels provided in the housing, so that a sound pressure in the ear canal can be exposed or released to the surrounding environment outside the earphones, and the pressure in the ear canal is reduced, and the sound experience of users is improved.
