Description

An earphone earmuff structure

technical field

The utility model relates to the technical field of earphones, in particular to an earmuff structure of an earphone.

Background technique

Headphones are important audio-visual equipment in modern life, and have become indispensable in work and life. When the earphone is used, it needs to be in close contact with the ear, which puts some pressure on the ear, and usually needs to be worn for a long time, so the comfort of the earphone is also very important. Usually, the earphone includes a headband, a housing arranged at both ends of the headband, and earmuffs sleeved on the housing, wherein a loudspeaker is arranged in the housing, and the headband and the earmuffs are important structures to ensure the comfort of the earphone. The adjustability of the band and the unit can ensure the use of different head shapes and different purposes. When adjusting the length of the headband, pay attention: the headband is short, the pressure on the top of the head is large, the pressure on the earmuffs is small, and the headband is long. On the contrary, it is most comfortable to balance the pressure at three points; and the earmuffs are used to directly contact the ears, avoiding direct contact between the shell made of plastic or metal materials and the ears, and the earmuffs must be soft , the elastic structure ensures that the earphones are comfortable during use; moreover, the earmuffs are also very important for the sound insulation effect of the earphones, whether it is the sound of the earphone itself or other sounds from the outside world, one is to avoid other sounds Interfering with the earphone user does not allow the earphone user to interfere with other persons.

Existing earmuffs are usually made of built-in sponge and outer leather or soft cloth. After long-term use, the sponge is prone to deformation and hollow, which makes the contact between the human ear and the earmuffs uneven, so that it cannot play a good role. Sound insulation effect, and the deformation of the earmuffs will cause pressure on the ears, making the human body feel uncomfortable.

Contents of the invention

The task of the utility model is to overcome the deficiencies of the above-mentioned prior art on the basis of the existing earmuff technical scheme, and provide an earmuff earmuff structure with reasonable structure, not easy to deform, good sound insulation and anti-noise effect, and comfortable to use.

The utility model is realized through the following technical solutions:

An earmuff structure for an earphone, comprising annular foam, a side support structure and an inner ring support structure, the inner ring support structure is arranged between the side support structures to jointly form an ear contact cavity and a loudspeaker accommodation cavity; the ring The foam is arranged in the ear contact chamber, the bottom is in contact with the inner ring support structure, and the side is in contact with the side support structure; when in use, the speaker of the earphone is arranged in the speaker accommodating chamber, and the ear contact chamber is in contact with the human ear. The annular foam forms a contact cavity adapted to the human ear, and the soft structure makes the ear feel comfortable, and the loudspeaker is arranged in the accommodating cavity to form an easily replaceable connection structure. Moreover, the foam has a good sound absorption effect, which is obvious for ensuring the sound isolation of the earphone.

Further, the upper part of the annular foam is provided with a skin, and the inner side is provided with an inner skin, and the dough and the inner skin are glued together by sewing or gluing; the outer side of the side support structure is provided with an outer skin, and the outer skin and the annular foam The upper part is provided with the frontal skin which is stitched or glued together. The outer skin is made of some soft materials, which is comfortable to touch, and the overall setting is beautiful and generous.

Further, a cloth layer is also provided between the annular foam and the inner ring support structure, and the cloth layer, the annular foam and the inner ring support structure are glued together, and the inner ring support structure is composed of a plastic sheet , the fabric layer and the inner ring support structure are provided with small holes to enhance the sound effect. The fabric layer keeps the inner ring support structure from direct contact, and the small holes enhance the sound transmission effect.

Further, the side support structure is composed of an annular silicone sheet, the lower part of which is inclined inward and has a certain radian; the middle part of the side support structure is provided with a raised structure, which is connected with the inner ring support structure; the lower part of the side support structure The end surface is connected with an elastic annular bottom surface. The diameter of the annular bottom surface is smaller than that of the loudspeaker and has good elasticity. The elastic annular bottom surface can fix the earphone speaker and is easy to install.

The beneficial effects of the utility model:

The earmuff structure in the utility model is provided with a side support structure and an inner ring support structure, so that the earmuff has the characteristics of good stability and is not easy to deform; a variety of soft leather and cotton materials are used to make the earmuff feel comfortable , The use of foam also makes the sound insulation and noise prevention effect good.
