Description

A kind of noise cancelling headphone

[technical field]

This utility model relates to a kind of earphone, is a kind of noise cancelling headphone in more detail.

[background technology]

In factory, noise is relatively big, affects relatively big on the audition of workman, and workman easily goes out for a long time in the environment of high noisy The occupation disease that existing ear auditory declines, existing acoustical insulation products has two classes, acoustic insulating ear plug and sound isolating earphone, and acoustic insulating ear plug is by sponge system Become, for a long time sponge is filled in ear and ear can be caused to ache, even can cause the internal inflammation of ear, outside sound isolating earphone is by plastics Shell adds deadener and makes, and its soundproof effect is not ideal, and existing earphone is all without safety alarming and identifying, night or light Work in Factory Building time not enough, be difficult to be found that accident easily occurs by other people.

[utility model content]

The purpose of this utility model is to provide a kind of noise cancelling headphone, with solve the earphone that proposes in above-mentioned background technology every The problem that audio fruit is bad, earphone does not have safety warning function.

For achieving the above object, this utility model following technical scheme of offer: a kind of noise cancelling headphone, it is bonded with reflecting strips Ring-type headband and two ear casings, two described ear casings are symmetricly set on the two ends of described ring-type headband, and described ear casing is The cylinder of inner hollow, its inner face caves inward and is formed for accommodating the groove of ear, and described ear casing Inner Constitution Vacuum sound insulation chamber.

Further, described groove is oval-shaped groove.

Further, the face of cylinder of described ear casing is provided with a plurality of crisscross anti-slip veins.

Further, the bottom of two described ear casings is connected to a fixing band, and described fixing band is provided with VELCRO, by the bonding connection of VELCRO between two described fixing bands.

Further, also include that foam-rubber cushion, described foam-rubber cushion are fixedly installed on the inner face of described ear casing.

Further, the outer face of described ear casing is outwardly formed a projection, described ring-type headband is provided with multiple The through hole suitable with described projection, described protruding and described through hole can be formed and be connected together, described ring-type headband and described ear Casing is removably connected by described through hole and described projection.

Further, the wall thickness of described ear casing is 35 millimeters.

The beneficial effects of the utility model are:

Simple in construction, easy to carry, can effectively intercept the noise in the external world, guarantee ear is not by noise injury, on earphone The reflecting strips arranged plays safe warning function, is easily found by other people, reduces the generation of security incident, the fixing band of increase It can be avoided that earphone is from the head landing of user, thus earphone is avoided to break.

[detailed description of the invention]

For making the purpose of this utility model, technical scheme and advantage clearer, below will be to technology of the present utility model Scheme is described in detail.Obviously, described embodiment is only a part of embodiment of this utility model rather than all Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not before making creative work Put obtained other embodiments all, broadly fall into the scope that this utility model is protected.

As shown in Figure 1-Figure 3, this utility model provides a kind of noise cancelling headphone, including: it is bonded with the ring-type head of reflecting strips 3 Band 1 and two ear casings 2, two ear casings 2 are symmetricly set on the two ends of ring-type headband 1, and ear casing 2 is the cylinder of inner hollow Body, its inner face caves inward and is formed for accommodating the groove 4 of ear, and ear casing 2 Inner Constitution vacuum sound insulation chamber 5, vacuum The effect of sound insulation is played in sound insulation chamber 5, and reflecting strips 3 bonding on ring-type headband 1 can increase alarm function, it is simple to by other Crinis Carbonisatus Existing.

Groove 4 is oval-shaped groove, similar to ear shape, and groove 4 is effectively combined with ear, increases soundproof effect.

It is provided with a plurality of crisscross anti-slip veins 6 on the face of cylinder of ear casing 2, increases the friction on ear casing 2 face of cylinder Power, it is simple to earphone of taking, the workman especially having can be stained with oil stain on hand, and the frictional force increasing ear casing 2 face of cylinder can subtract Few earphone danger of landing from hands, increases the service life of earphone.

The bottom of two ear casings 2 is connected to a fixing band 7, and fixing band 7 is provided with VELCRO, fixes for two By the bonding connection of VELCRO between band 7, two fixing bands 7 are fixed on chin, it is possible to avoid earphone from head landing, Gu Surely the VELCRO with arranging on 7 plays the function of convenient disassembly, and can be finely adjusted solid according to the size of oneself chin Surely with 7 connecting length.

Also include that foam-rubber cushion 8, foam-rubber cushion 8 are fixedly installed on the inner face of ear casing 2, can be by ear casing 2 during use Seal with ear, increase the soundproof effect of earphone.

The outer face of ear casing 2 is outwardly formed a projection 9, and protruding 9 is that mushroom-shaped is protruding, its top semicircular in shape, under Portion is cylinder, and ring-type headband 1 is provided with multiple and protruding 9 suitable through holes 10, and protruding 9 can be formed with through hole 10 and to engage Connecting, ring-type headband 1 is removably connected, by the projection 9 on ear casing 2 with ring-type by through hole 10 and protruding 9 with ear casing 2 Through holes 10 different on headband 1 is attached, and can adjust the length of ring-type headband 1, to adapt to the head of different users, with Shi Huanzhuan headband 1 can rotate freely along protruding 9, selects suitable angle to place ring-type headband 1.
