Embodiment Construction

[0025] Referring to the accompanying drawings, the present invention will be further described in detail with specific embodiments.

[0026] Such as figure 1 and 3 As shown, the present invention includes an earplug sleeve 1, an airway 2 and an ear hook 3. The earplug cover 1 is a hollow structure, and three sealing rings are arranged on the outside, and the three sealing rings are umbrella-shaped structures, which play the role of waterproofing.

[0027] One end of the air duct 2 is inserted into the earplug sleeve 1 to cooperate with the hollow part of the earplug sleeve 1 , and the other end is connected with the ear hook 3 .

[0028] The material of the earplug cover 1 can be flexible polymer materials such as silica gel, or sponge.

[0029] Such as image 3 As shown, the middle position in the airway tube 2 is the middle cavity 5, and one end (near the ear canal end) of the airway tube 2 is provided with a narrow and long micro-perforation 4, and the other end of the ...

Abstract

The invention relates to earplugs and solves technical problems that existing listening protection earplugs are not breathable, air pressure inside and outside ear canals is not balanced and alertness of users to surroundings is reduced. Each earplug comprises an earplug sleeve and an air guide tube, wherein the earplug sleeve adopts a hollow structure, sealing rings are arranged on the outer side of the earplug sleeve, the air guide tube is provided with a middle cavity and two ends, one end, where a through hole is formed, of the air guide tube is arranged in the earplug sleeve, a through hole is also formed in the other end of the air guide tube, and the through hole in at least one end of the air guide tube is a micro through hole. The earplugs can be widely applied to listening protection, the noise reduction effect of the earplugs has amplitude selectivity, and the earplugs have a good noise reduction effect on high sound pressure and have small attenuation effects on low sounds.

Description

technical field [0001] The invention relates to an earplug, in particular to an earplug with good air permeability and selective noise reduction for sounds with different amplitudes. Background technique [0002] Noise has become a major pollution in modern society. People exposed to high-decibel loud noise for a long time will cause a series of diseases such as hearing loss. Earplugs can reduce noise and protect hearing, and are widely used in high-sound pressure environments, such as industrial production, construction, transportation, stage performances, and other fields. However, in order to effectively reduce noise, the existing noise-reducing earplugs completely seal the entire ear canal, and the isolation of the ear canal from the external environment will cause air pressure imbalance, which is not conducive to long-term wearing. Moreover, too much noise reduction reduces the user's awareness of the surrounding environment, which is not conducive to safe use. For ex...
