Description

Silica gel earmuff with good fitting performance and durability

Technical Field

The utility model belongs to the earmuff field gives sound insulation, in particular to silica gel earmuff that laminating nature is good, the durability is good.

Background

The headset is required to be provided with the earmuffs, so that the effects of reducing external noise and improving wearing comfort are achieved. Some traditional earmuffs are made by wrapping filling materials with exterior materials (such as leather sleeves and cloth sleeves) and some traditional earmuffs are made by directly compressing materials. Although the earmuff has a certain effect on isolating external noise, the earmuff also has the defects of small compression amount, poor fitting property, high cost and low durability, and the sound insulation effect and the wearing comfort are poor.

If the prior patent with the publication number of CN203618103U discloses a silica gel earmuff, which comprises a soft silica gel bag, wherein the soft silica gel bag is an annular hollow sealing structure, a liquid heat-conducting filler is filled in an inner cavity, and sound insulation is realized by utilizing the characteristic impedance difference between silica gel and air. But because this silica gel earmuff is seal structure, incompressible, the facial shape of automatic laminating is difficult to, and sound insulation effect and wearing comfort are all relatively poor.

If the prior patent with the publication number of CN207802298U discloses a silica gel earmuff applied to noise reduction earphones in tactical occasions, the silica gel earmuff comprises a face mask and a cover plate, wherein the face mask is fixedly connected with the cover plate, and the cover plate is connected with an earphone shell; the mask comprises soft silica gel, and the upper part of the mask is provided with at least one circle of avoiding guide groove. Although this patent has a certain sound insulation effect by separating the soft silicone rubber from the sponge, the soft silicone rubber on the upper portion thereof has a limited compressed amount, and thus has problems of a small compressed amount and poor adhesion.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problems, the primary object of the present invention is to provide a silicone earmuff with good adhesiveness and durability, which has a large compression amount and good adhesiveness, and has excellent sound insulation effect;

another object of the utility model is to provide a silica gel earmuff with good fitting property and durability, which is comfortable to wear;

still another object of the utility model is to provide a silica gel earmuff that the laminating nature is good, the durability is good, simple structure, with low costs, convenient to use and popularization.

In order to achieve the above purpose, the technical scheme of the utility model is as follows:

the utility model provides a silica gel earmuff that laminating nature is good, durability is good, including earmuff foreskin, earmuff support, packing sponge, earmuff support and earmuff foreskin fixed connection, the earmuff foreskin has the open-ended loop configuration for the mould shaping, and the inside of earmuff foreskin is provided with the cavity, it fills in the cavity to fill the sponge, still is provided with the bonding locating hole on the earmuff foreskin, and the earmuff support is provided with the bonding reference column that corresponds with bonding locating hole position, is provided with the exhaust hole that communicates with the cavity on the bonding reference column, earmuff foreskin, earmuff support, packing sponge assembly form an inclosed assembly. In the application, the silica gel material is used for replacing the traditional artificial leather material, so that the artificial leather is more durable. The earmuff wrapper can be arranged on the loudspeaker cover of the earphone through the earmuff bracket. The earmuff foreskin fills sponge cooperation exhaust hole to the cavity intussuseption from the opening part, and when the earmuff was compressed and recovered the shape, the release of air reached with the exhaust hole that gets into through the earmuff support, can make things convenient for and exhaust when the earmuff compressed, effectively increases the decrement of earmuff, and easy laminating people's face forms better airtight syllable-dividing effect, and the sense of touch is softer.

Furtherly, earmuff foreskin, earmuff support, the filling sponge in the assembly are undetachable each other and are connected, the earmuff foreskin still including the buckle, with the position looks lock that the earmuff support corresponds on the cavity. In this application, the main part of earmuff support passes through the buckle joint in the earmuff wrapper, also can replace the lock with the mode of magnetite actuation, through buckle or magnetism inhale the mode installation earphone on the horn cover, simple structure, firm, convenient dismantlement.

Furthermore, the earmuff bracket and the buckle plate are bonded by glue, and a bonding surface is formed between the earmuff bracket and the earmuff wrapper. A sealed space is formed in the ear cap wrapper, air can only enter and exit from the air exhaust hole, and the air compression device is more stable in compression and air exhaust. After the product installation is used, the gas pocket position on the earmuff support aligns with the gas pocket position that the loudspeaker was covered, and the air in the earmuff is arranged inside the earphone shell, does not directly arrange in the space of freedom, and outside sound is fully kept apart, and the noise reduction effect is good.

Further, the filling sponge is made of an inert sponge material. The inertia sponge is soft, the compression ratio is relatively larger than that of the conventional sponge, the compression deformation is easier, different face shapes can be attached more easily during use, and the inertia sponge is more comfortable. The silica gel material is used for replacing the traditional artificial leather material, and the artificial leather is more durable

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

firstly, the silica gel earmuff is filled with sponge inside the earmuff wrapper and matched with the exhaust hole, so that the earmuff can be conveniently exhausted when compressed, the compression amount of the earmuff is effectively increased, and the earmuff is easy to fit the face of a person to form a better closed sound insulation effect;

secondly, the vent holes of the earmuff are arranged on the earmuff support, the earmuff support is bonded on the earmuff wrapper through an adhesive layer, a sealed space can be formed inside the earmuff wrapper, air in the earmuff is discharged inside the earphone shell and is not directly discharged in a free space, external sound is fully isolated, and the noise reduction effect is good;

finally, the utility model discloses simple structure, with low costs, convenient to use and popularization.
