Windproof noise reduction earphone

Abstract

The invention relates to a windproof noise reduction earphone. The windproof noise reduction earphone comprises a wire body and a shell; a bearing plate is arranged in the shell, the bearing plate divides the inner cavity of the shell into a front cavity and a back cavity, and the front cavity and the back cavity communicate with each other through a sound transmission hole; a feedback microphoneis installed in the front cavity, a collection microphone is installed in the back cavity, a windproof cover is installed at the tail of the back cavity, and an annular flange and an annular chute, which are matched with each other, are respectively arranged on opposite contact surfaces of the windproof cover and the shell; the interior of the windproof cover is hollow to form a windproof cavity,and the windproof cavity communicates with the back cavity through a flow guide opening; the outer cover surface of the windproof cover is of a convex streamline type, a splitting fin is arranged at the tail of the streamlined outer cover surface, and an air vent is formed in the tail end of the streamlined outer cover surface. The windproof noise reduction earphone has a simple structure, can intelligently adjust and handle high-speed airflow in various directions, effectively reduce the noise generated by the high-speed airflow when passing through the earphone main body and improve the noise reduction experience of the earphone.

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.
