Description
Technical field
The utility model relates to earplug technical field, particularly relates to a kind of built-in earplug can protecting ear-drum when pullling earphone cord.
Background technology
In-Ear Headphones, have another name called ear-canal earphones, built-in earplug or In-Ear monitor (i.e. the English full name of IEM: In-Ear-Monitor), it is a kind of earphone being used in human body hearing organ inside, the earplug set that low resilience material is made when wearing inserts in duct, seal up the duct of user, to obtain better seal.Built-in earplug, because of outstanding Portability and outstanding soundproof effect, becomes the main flow of earplug product.
But this In-Ear Headphones structure is when wearing, if having external force to pull rapidly earphone cord have the possibility of damaging or even tearing eardrum.This is because: when people wear built-in earplug, duct can seal by earplug set completely, when earplug be rapidly to outer mobile time in duct, form very large negative pressure, bear the limit and will damage if negative pressure exceedes eardrum and even tear eardrum.At present existing many because earphone cord hangs over it the pedestrian that passes each other so close that they almost rubbed each other, or other people speak because user does not hear it and pull at earphone cord and cause the case that user's eardrum is torn.
Current In-Ear Headphones there is no a kind of safeguard construction of tackling above-mentioned risk.
Utility model content
The object of the utility model embodiment is for the structural shortcoming of prior art; a kind of built-in earplug can protecting ear-drum when pullling earphone cord is proposed; earplug body and earphone cord arrange audio terminal and source of sound plug socket respectively; exceed before eardrum bears the limit when being applied to the pulling force between source of sound plug socket; the two is separated, and ensure that the safety of user thus.
In order to reach above-mentioned utility model object, a kind of of the utility model embodiment proposition can protect the built-in earplug of ear-drum to be achieved through the following technical solutions when pullling earphone cord:
A kind of built-in earplug can protecting ear-drum when pullling earphone cord, comprise earplug body, headset plug and the earphone cord be connected between described earplug body and headset plug, described earplug body comprises shell, be located at the loud speaker in described shell and socket earplug set on the housing, described earplug set is made up of low resilience material, it is characterized in that: described shell is convexly equipped with a columned audio terminal, the end face of described audio terminal is provided with the fixed contact that two are electrically connected described loud speaker, and the center of its end face depression is provided with a location hole, the sidewall of described audio terminal is equipped with groove, described earphone cord is provided with described audio terminal shape adaptation relative to the other end of headset plug and may correspond to the source of sound plug socket of grafting, the bottom surface of described source of sound plug socket is provided with two are electrically connected described headset plug contact by earphone cord, and its place of bottom center is convexly equipped with the alignment pin with described location hole form fit, described source of sound plug socket is made up of flexible material around the tube wall of bottom surface, and inner side forms the flange with described groove shapes adaptation.
The section configuration of described groove is that semicircle or minor arc are arc.
Compared with prior art; the beneficial effects of the utility model are: propose a kind of built-in earplug can protecting ear-drum when pullling earphone cord; the earplug body of this earplug and earphone cord arrange audio terminal and source of sound plug socket respectively; exceed before eardrum bears the limit when being applied to the pulling force between audio terminal and source of sound plug socket; audio terminal is separated with source of sound plug socket, ensure that the safety of user thus.Its structure is simple, with low cost, suitable wide popularization and application in industry.
Accompanying drawing explanation
By the description carried out its exemplary embodiment below in conjunction with accompanying drawing, the above-mentioned feature and advantage of the utility model will become apparent and easy understand.
Fig. 1 is the utility model embodiment overall structure schematic diagram;
Fig. 2 is the utility model embodiment audio terminal and source of sound plug socket coupling part schematic diagram I;
Fig. 3 is the utility model embodiment audio terminal and source of sound plug socket coupling part schematic diagram II.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, so that the understanding of technical staff of the same trade:
As Figure 1-3; a kind of built-in earplug can protecting ear-drum when pullling earphone cord is provided in the present embodiment; the same with conventional built-in earplug; it earphone cord 3 comprising two earplug body 1 (because earplug body, headset plug and earphone cord structure are those skilled in the art's routine techniques, therefore only drawing an earplug body in accompanying drawing 1), headset plug 2 and be connected between earplug body 1 and headset plug 2.Wherein: the earplug set 12 that earplug body 1 comprises shell 11, is located at the loud speaker (not shown) in shell 11 and is socketed on shell 11, earplug set 12 is made up of low resilience material.Headset plug 2 is 3.5mm headset plug.Earphone cord 3 quad, comprises L channel line, R channel line, L channel ground wire, R channel ground wire.
Be different from conventional built-in earplug:
Shell 11 is convexly equipped with audio terminal 13, audio terminal 13 is roughly in cylindrical shape.Its end face is provided with the fixed contact 131 that two are electrically connected loud speaker in shell 11, and the center of its end face depression is provided with a location hole 132.In addition, the sidewall of audio terminal 13 is equipped with groove 133.Grooved section shape is that minor arc is arc.
The other end of the relative headset plug 2 of earphone cord 3 is provided with source of sound plug socket 4, and barrel-shaped in audio terminal 13 shape adaptation of source of sound plug socket 4, source of sound plug socket 4 and audio terminal 13 may correspond to grafting.The bottom surface of source of sound plug socket 4 is provided with two contacts 41 be electrically connected by core in earphone cord 3 and headset plug 2, and the place of bottom center of source of sound plug socket 4 is convexly equipped with the alignment pin 42 with location hole 132 form fit.Source of sound plug socket 4 is made up of flexible material around the tube wall 43 of bottom surface, and the inner side of tube wall 43 forms the flange 431 with groove 133 shape adaptation.
See Fig. 3, when connecting earplug body 1 and earphone cord 3, turned up by tube wall 43, insert until the end in location hole 132 by alignment pin 42 afterwards, now contact 41 contacts fixed contact 131, realizes being electrically connected between earphone cord 3 and earplug body 1.Overturn by the tube wall 43 turned up afterwards, the flange 431 on tube wall 43 is embedded in groove 133.
When being applied to the pulling force between source of sound plug socket and being less, the flange 431 be embedded in groove 133 ensure that being fixedly connected with of earplug body and earphone cord.When earphone cord is quickly pulled, exceeding before eardrum bears the limit, namely tube wall 43 can depart from from audio terminal 13, ensure that the safety of people's ear.
By embodiment, invention intention of the present utility model and execution mode are described in detail above; but the utility model one of ordinary skill in the art be appreciated that; the above embodiment of the utility model is only one of preferred embodiment of the present utility model; for length restriction; here can not all execution modes of particularize; any enforcement that can embody the utility model claim technical scheme, all in protection range of the present utility model.
