Description

Three-layer foam noise-reducing earplug

Technical Field

The utility model relates to the technical field of earplugs, in particular to a three-layer foam noise reduction earplug.

Background

The headphones are a pair of conversion units that receive electrical signals from the media player or receiver and convert them into audible sound waves using a speaker proximate the ear. The earphone can be separated from the media player, can be connected by only one plug, and can independently listen to the sound without affecting other people; can also isolate the sound of the surrounding environment, and is helpful for people in the noisy environment, such as recording studio, bar, trip, sports, etc.

The earplug is one of the components of the earphone, the earphone is connected with the ear, and the earphone is plugged into the auditory canal when in use; the earplug has the main functions of isolating external noise, providing better tone quality experience, and simultaneously enabling a user to use the earphone more comfortably; however, the ear canal structure of each person has different shapes, sizes and dimensions, and part of the ear plugs are composed of the inner tube and the sponge, so that the ear canal structure can be adapted to different types of ear canals through the design of the sponge, but the sponge has poor sound insulation effect, so that improvement is needed.

Disclosure of Invention

The utility model solves the technical problems of the prior art by providing a three-layer foam noise reduction earplug, so as to solve the problems that part of the earplug provided in the prior art consists of an inner tube and a sponge, the sponge can adapt to different types of auditory meatus, but the sponge has poor noise insulation effect.

In order to solve the technical problems, the utility model adopts the following technical scheme:

a three layer foam noise reducing earplug comprising: an inner tube, a sound insulation layer and foam cotton;

the inner pipe is internally provided with a channel and is made of hard rubber; the inner tube comprises a sound inlet hole and a sound outlet hole, the sound inlet hole is used for being connected with the earphone, and the sound outlet hole is used for extending into ears of a user;

the sound insulation layer is sleeved on the inner tube, is umbrella-shaped, is made of silica gel, and is provided with a first through hole at a position where the sound insulation layer is abutted to the sound outlet hole;

foam cotton is laminated and sleeved on the sound insulation layer, the foam cotton is umbrella-shaped, the foam cotton is made of memory cotton, and a second through hole is formed in the position, abutting against the first through hole, of the foam cotton.

By arranging the silica gel sound insulation layer between the foam cotton and the inner tube, external sound is isolated from entering, audio signals in the inner tube can not leak out, a good reverberation resonance environment is formed, noise is reduced, sound is insulated, and good audio-visual feeling can be obtained; therefore, the problem that the earplugs in the background art are composed of the inner tube and the sponge and can adapt to different types of auditory meatus through the design of the sponge, but the sponge has poor sound insulation effect is solved.

Further, the foam cotton internal structure is honeycomb.

Compared with the prior art, the utility model has the beneficial effects that:

1. through the design of foam cotton, the utility model can adapt to different types of auditory meatus when worn, and is more comfortable;

2. through set up the puigging of silica gel material in the middle of foam cotton and inner tube, not only isolated external sound gets into, can also let the music in the inner tube can not leak, forms good reverberation resonance environment, falls noise insulation, can obtain fine audio-visual impression.
