Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] The invention provides an earmuff, which comprises a body with an inner cavity and an ear pad arranged on the edge of the inner cavity. The ear pad is an oval ring structure adapted to the shape of the outer ear. The ring sidewall has a grid mesh.

[0022] In the present invention, the inner side of the earpad is designed as a breathable grid net, on the one hand, the equivalent volume of the earpad itself is increased, so that the required equivalent volume and appropriate damping coefficient can be obtained in the earmuff, preventing the occurrence of Self-excited, which reduces the negat...

Abstract

The invention provides an ear shield and a head-mounted noise reduction earphone using the ear shield, which are applicable to the technical field of electronic products. The ear shield comprises a body having a cavity and an ear pad arranged in edge of the cavity; the ear pad is in an oval ring structure suitable to the shape of an ear; and grid net is arranged in the inner side wall of the ear pad ring structure. In the invention, the inner side of the ear pad is designed into the ventilated grid net; when the ear shield is applied to the earphone, an equivalent volume of the ear shield is increased, so that the needed equivalent volume and an appropriate damping coefficient can be obtained in the ear shield, self-excitation can be prevented, and a negative pressure effect generated under a closed state can be reduced; on the other hand, through the ventilated grid net, a frequency response superimposed effect generated in a coupling or feeding back process can be improved; a sound pressure level peak value and a bandwidth uniformity generated by sound wave reflection can be reduced; simultaneously, the grid net is excellent in ventilation property, and comfortable degree of users when wearing the earphone is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of electronic products, and more specifically relates to an earmuff and a head-mounted noise reduction earphone using the earmuff. Background technique [0002] With the continuous improvement of living standards, listening to music has become a way for people to relieve their mood and reduce stress in their spare time. At the same time, with people's continuous pursuit of high-quality life, people also have higher requirements for the quality of earphones. The manufacturer starts from the combination of humanistic care and health concepts, in order to allow every user to listen to the pure sound of life in a noisy environment, and to protect hearing, and develops intelligent noise-cancelling headphones to meet the needs of consumers. . [0003] The noise reduction headphones currently on the market mainly achieve noise reduction through internal circuits, but there is no special noise reduction treatment ...
