Description

A kind of new earplug

Technical field

This utility model relates to sphere of life, particularly relates to a kind of new earplug.

Background technology

The earplug product of earliest period comes from Europe, and waxed earplug is material the most traditional.Afterwards because the continuous research and development of new material upgrade, a kind of resilient material became the main flow making acoustic insulating ear plug gradually.Earplug has high efficiency shielding noise, adapts to the effect of noisy environment, and current ear phone structure is simple, the reduction effect of noise is too little, and can auditory meatus fill very full very uncomfortable, pine and can not effective blocking noise excessively.

Utility model content

For this reason, this utility model provides a kind of new earplug, this utility model has been selected and has been improved sound-insulating structure, employ baffle and acoustical cotton carries out dual sound insulation, enhance the soundproof effect of earplug, brand-new design is carried out for housing and fixed structure simultaneously, Consumer's Experience can be improved simultaneously, in fixation procedure, can not pain be produced.

The technical scheme that this utility model solves the problems of the technologies described above is as follows:

A kind of new earplug, comprise housing, fixed structure and sound absorption structure, described fixed structure is the conical rubber circle be arranged on described housing exterior walls, described housing is in being horizontally disposed with the cylinder blanket with cavity, described enclosure interior comprises multiple sound insulation plate, described enclosure interior is filled with acoustical cotton, and described hull outside and inside are provided with helicitic texture

The two sides of baffle is all equipped with sound absorbing layer, one side is equipped with the sound absorbing layer made with glass cotton, another side is equipped with the sound absorbing layer made with foam plastics, described acoustical cotton possesses layer multi-layer loose structure, described acoustical cotton sets gradually non-woven fabrics puigging, high polymer fibre sound absorbing layer from inside to outside, and is provided with adhesive linkage between non-woven fabrics puigging and high polymer fibre sound absorbing layer.

Preferably, the number of described baffle is 10-30.

The beneficial effects of the utility model are:

This utility model provides a kind of new earplug, this utility model has been selected and has been improved sound-insulating structure, employ baffle and acoustical cotton carries out dual sound insulation, enhance the soundproof effect of earplug, brand-new design is carried out for housing and fixed structure simultaneously, Consumer's Experience can be improved simultaneously, in fixation procedure, can not pain be produced.

Accompanying drawing explanation

Fig. 1 is a kind of new earplug schematic diagram.

Wherein: 1-housing, 2-fixed structure, 3-baffle.

Detailed description of the invention

For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, this utility model is described in further detail.

In one embodiment, as shown in Figure 1, a kind of new earplug, comprise housing 1, fixed structure 2 and sound absorption structure, described fixed structure 2 is for being arranged at the conical rubber circle on described housing 1 outer wall, and described housing 1 is in being horizontally disposed with the cylinder blanket with cavity, described housing 1 inside comprises multiple sound insulation plate 3, described housing 1 inside is filled with acoustical cotton, and described housing 1 is outside is provided with helicitic texture with inside

The two sides of baffle is all equipped with sound absorbing layer, one side is equipped with the sound absorbing layer made with glass cotton, another side is equipped with the sound absorbing layer made with foam plastics, described acoustical cotton possesses layer multi-layer loose structure, described acoustical cotton sets gradually non-woven fabrics puigging, high polymer fibre sound absorbing layer from inside to outside, and is provided with adhesive linkage between non-woven fabrics puigging and high polymer fibre sound absorbing layer.

Preferably, the number of described baffle 3 is 10-30.

Above disclosedly be only this utility model preferred embodiment, certainly can not limit the interest field of this utility model with this, therefore according to the equivalent variations that this utility model claim is done, still belong to the scope that this utility model is contained.
