Abstract

The utility model discloses a safe earphone and includes an earphone shell. At least one through hole is arranged on the earphone shell, and the through hole is a round hole, a square hole or a polygonal hole. When a user is using the earphone, the body auditory meatus is communicated with outside natural atmosphere by the through hole, and the sound pressure produced by the earphone dissipates outwards by the through hole, thus effectively reducing the stimulation and damage from vibration and sound pressure to the eardrum and the auditory nerves, reducing the pressure of sound pressure to the eardrum, and achieving the purpose of ears protection.

Description

Safe earphone

Affiliated technical field

The utility model relates to a kind of earphone, relate in particular a kind of can be in use, effectively reduce vibration and acoustic pressure safe earphone to the stimulation and the infringement of ear-drum and hearing nerve.

Technical background

At present, that known earphone is divided into is traditional, three kinds of wear-type and earplugs, when using these earphones, earphone horn is covered fully or inserts in the duct of human body, make whole sound, the vibration ear-drum via duct, thereby stimulate the neural generation of the hearing sense of hearing, but the pressure that vibration produces also all acts directly on the ear-drum, and long-time use can make the user cause hearing loss, and user's hearing is caused damage.

The utility model content

The purpose of this utility model is to overcome above-mentioned defective in the prior art: provide a kind of simple in structure, can reduce acoustic pressure to the stimulation of human body ear-drum and the stimulation of hearing nerve, effectively protect the safe earphone of user's ear.

For achieving the above object, the technical scheme that the utility model provides is as follows: construct a kind of safe earphone, comprise earphone case, be provided with a through hole at least on described earphone case.

Described through hole is circular port, square opening or polygonal hole.

The beneficial effect of safe earphone described in the utility model is: by a through hole is set on described earphone case at least; the user is when using earphone; human antrum auris is connected with extraneous the Nature air by this through hole; the acoustic pressure that earphone produces outwards dissipates by this through hole; effectively reduce stimulation and the infringement of vibration and acoustic pressure to ear-drum and hearing nerve; reduce the compressing of acoustic pressure, reach the purpose of protection ear ear-drum.

Below in conjunction with drawings and Examples safe earphone described in the utility model is described further:

Fig. 2 is the structural representation of Fig. 1 when inserting the human body ear;

Fig. 3 is the partial structurtes schematic diagram of using on headphone of the utility model safety earphone.

Embodiment

Below the most preferred embodiment of safe earphone described in the utility model, therefore do not limit protection range of the present utility model.

With reference to Fig. 1, a kind of safe earphone is provided, this safe earphone is an earplug, comprise earphone case 1, be provided with three through holes 2 on described earphone case 1, described through hole 2 is circular port, square opening or polygonal hole, can at earphone case 1 one or several through holes 2 be set according to actual needs.

With reference to Fig. 2; safe earphone described in the utility model is inserted in the duct of human body ear 3; human antrum auris is connected with extraneous the Nature air by this through hole 2; the acoustic pressure that earphone produces outwards dissipates by this through hole; effectively reduce stimulation and the infringement of vibration and acoustic pressure to ear-drum and hearing nerve; reduce the compressing of acoustic pressure, thereby effectively protect ear ear-drum.

With reference to Fig. 3, a kind of safe earphone is provided, this safe earphone is a headphone, comprise earphone case 1, be provided with three through holes 2 on described earphone case 1, described through hole 2 is circular port, square opening or polygonal hole, can at earphone case 1 one or several through holes 2 be set according to actual needs.

Claims (2)

1. a safe earphone comprises earphone case (1), it is characterized in that, is provided with a through hole (2) on described earphone case (1) at least.

2. safe earphone according to claim 1 is characterized in that, described through hole (2) is circular port, square opening or polygonal hole.
