Abstract

The utility model discloses a vacuum sound-proof earphone which includes an elastic head belt and two side units. The two side units are connected with the two ends of the head belt. Each side unit includes an outer housing and a soft pad. The outer housing is sealed, and the middle of the outer housing is a vacuum sound-proof cavity. The soft pad is arranged on the inner side of the housing. The soft pads of the two side units are opposite to each other. The vacuum sound-proof earphone can effectively keep out the external noise, and is excellent in sound insulation effect.

Description

The vacuum sound insulation earphone
Technical field
The utility model relates to a kind of vacuum sound insulation earphone.
Background technology
Along with the quickening of present rhythm of life, people also need to be had a rest more fully, in the rest process, for reducing the interference of outside noise; In work or learning process, also often need to intercept extraneous noise, most of mode that adopts is now: beyond the Great Wall earplug or the Sound-proof material in ear that have, and the traditional earphone of the employing that has stops extraneous noise, but traditional practice, its soundproof effect is all not ideal.
Summary of the invention
Based on this, the utility model is to overcome the defective of prior art, and a kind of vacuum sound insulation earphone is provided, and the utility model can effectively intercept extraneous noise, and soundproof effect is good.
Its technical scheme is as follows:
A kind of vacuum sound insulation earphone comprises elasticity headband and two side units, and two side units are connected to the two ends of headband, each side unit comprises shell body and cushion, the shell body sealing, and its middle part forms the vacuum sound insulation chamber, cushion is located at the inboard of shell body, and the cushion of two side units is relative.
The below describes further technical scheme:
Described cushion is foam-rubber cushion.
Described shell body is circle drum.
The two ends of two described headbands all have two journal stirrups, have rotating shaft between two journal stirrups, and described shell body is movably connected in the rotating shaft.
Inboard at two described shell bodies is equipped with loud speaker, and loud speaker and audio signal wire are electrically connected.
The below describes advantage or the principle of aforementioned techniques scheme:
1, under the effect of elasticity headband, two side units are close to ear, and the cushion of side unit can strengthen attaching effect, feel also more comfortable, and the vacuum sound insulation chamber on the side unit can effectively intercept extraneous noise, improve soundproof effect.
2, described shell body is circle drum, and is easy to process, more identical with ear shape, and can guarantee to form effective vacuum sound insulation chamber.
3, side unit is connected to by rotating shaft on two journal stirrups of elasticity headband, and side unit rotates flexibly, can better fit with ear.
4, also be provided with loud speaker on side unit, can also pass through this earphone music playing, as playing light music, can allow the user further be loosened, the setting in vacuum sound insulation chamber in the shell body can also well anti-leak-stopping sound phenomenon.

Fig. 2 is the partial enlarged drawing of elasticity headband and side unit junction;
Description of reference numerals:
10, elasticity headband, 11, journal stirrup, 12, rotating shaft, 20, side unit, 21, shell body, 22, cushion, 23, the vacuum sound insulation chamber.
Embodiment
The below is elaborated to embodiment of the present utility model:
As shown in Figure 1 and Figure 2, a kind of vacuum sound insulation earphone, comprise elasticity headband 10 and two side units 20, two side units 20 are connected to the two ends of headband, each side unit 20 comprises shell body 21 and cushion 22, shell body 21 sealings, and its middle part forms vacuum sound insulation chamber 23, cushion 22 is located at the inboard of shell body 21, and the cushion 22 of two side units 20 is relative.
Wherein, described cushion 22 is foam-rubber cushion, and described shell body 21 is circle drum.The two ends of two described headbands all have between 11, two journal stirrups 11 of two journal stirrups and have rotating shaft 12, and described shell body 21 is movably connected in the rotating shaft 12.Inboard at two described shell bodies 21 is equipped with loud speaker, and loud speaker and audio signal wire are electrically connected.
Present embodiment has following advantage:
1, under the effect of elasticity headband 10, two side units 20 are close to ear, and the cushion 22 of side unit 20 can strengthen attaching effect, feel also more comfortable, and the vacuum sound insulation chamber 23 on the side unit 20 can effectively intercept extraneous noise, improve soundproof effect.
2, described shell body 21 is circle drum, and is easy to process, more identical with ear shape, and can guarantee to form effective vacuum sound insulation chamber 23.
3, side unit 20 is connected to by rotating shaft 12 on two journal stirrups 11 of elasticity headband 10, and side unit 20 rotates flexibly, can better fit with ear.
4, also be provided with loud speaker on side unit 20, can also pass through this earphone music playing, as playing light music, can allow the user further be loosened, the setting in shell body 21 interior vacuum sound insulation chambeies 23 can also well anti-leak-stopping sound phenomenon.
The above embodiment has only expressed embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.
