Noise reduction earplug capable of being automatically separated from ear canal at regular time

Abstract

The invention discloses a noise reduction earplug capable of being automatically separated from an ear canal at regular time. The noise reduction earplug comprises a control mechanism, a rotation mechanism and a fixing mechanism. The control mechanism comprises a control mechanism shell, a power source, a controller / timer, a display screen and a bayonet, and the rotation mechanism comprises a rotation mechanism shell, a spiral coil fixing shaft, a spiral coil, a turntable, a clamp plate, an earplug line and an earplug; the control mechanism shell, the rotation mechanism shell and the fixing mechanism keep being fixedly positioned. The noise reduction earplug capable of being automatically separated from the ear canal at regular time has the advantages that the earplug can be taken out of the ear canal at regular time, so that a sound insulation effect of the earplug can stop being realized at specific moments, and a user can automatically regain the ability of receiving external effective audio information; the noise reduction earplug is simple in structure and low in power consumption.

Description

technical field [0001] The invention relates to a noise-reducing earplug which can automatically detach from the ear canal at regular intervals. Background technique [0002] Usually, the earplug is often made of a cylinder made of special material, which has good ductility and can be sent into the ear canal when pinched flat, and then expands and fills the ear canal due to the material's own characteristics, thereby achieving a seal on the ear canal . Another design of vacuum sound-isolating earplugs uses the sound-proofing effect of the vacuum layer. The earplug designs above all discuss how to enhance the sound insulation effect, but they all face the same problem, that is, unless the user takes off the earplugs, the earplugs will always maintain isolation from external audio information. Therefore, the existing solution will set a timing and sounding device inside the earplug. This method has its advantages, but it also faces problems such as high circuit structure req...

AI Technical Summary

Problems solved by technology

The above earplug designs are all about how to enhance the sound insulation effect, but they all face the same problem, that is, unless the user takes off the earplugs, the earplugs will always maintain isolation from external audio information

Therefore, the existing scheme will set a timing and sounding device inside the earplug. This method has its advantages, but it also faces problems such as high circuit structure requirements, poor sound insulation effect of the earplug, high cost, and damage to the eardrum.
