Windproof and Noise Canceling Headphones

Abstract

The invention relates to a windproof and noise-reducing earphone. The windproof and noise-reducing earphone includes a wired body and a housing; The rear chambers are connected through sound transmission holes; feedback microphones are installed in the front chamber, collection microphones are installed in the rear chamber, and a windshield is installed at the tail of the rear chamber, where the windshield is in direct contact with the shell There are matching annular ribs and annular chute respectively on the surface; the inside of the windshield is hollow to form a windproof cavity, and the windproof cavity and the rear cavity are connected through a diversion port; the outer surface of the windshield is convex and streamlined, A splitter fin is set at the tail of the streamlined outer cover, and a vent is opened at the tail of the streamlined outer cover; the windproof and noise-cancelling earphones have a simple structure, can be intelligently adjusted, and can deal with high-speed airflow in various directions, effectively reducing the passage of high-speed airflow The noise generated by the headphone body improves the noise reduction experience of the headphone.

Description

technical field [0001] The invention relates to an earphone, in particular to a noise reduction earphone. Background technique [0002] Noise-cancelling headphones are divided into active noise-cancelling headphones and passive noise-cancelling headphones. Active noise-cancelling headphones pick up sound waves from the external environment, and after analysis and comparison, they instantly emit sound waves with opposite waveforms. The external sound waves and the opposite sound waves enter the ear canal at the same time, and finally cancel each other out, so as to achieve noise elimination; because analysis and comparison take a certain amount of time, most of the civilian earphones currently on the market can only eliminate continuous environmental noise, and cannot make adjustments for sudden sounds. The noise canceling function of the noise-canceling earphones is not perfect; at the same time, the noise-cancelling earphones cannot be used in windy weather or when riding, ...

The noise canceling function of the noise-canceling earphones is not perfect; at the same time, the noise-cancelling earphones cannot be used in windy weather or when riding, and will generate large wind noise, which seriously affects the normal use of users outdoors.
