Abstract
The utility model discloses an earphone with a circular-hole interface of 3.5 mm. The earphone comprises a metal earphone plug. The metal earphone plug comprises a left channel, a right channel, a ground wire and a micro anode which are arranged in order from top to bottom. The truncation place between the micro anode and the ground wire is parallelly connected with a six-foot circuit switching switch. The circuit exchange switch is equipped with a hand free box. According to a circuit structure of a mobile phone earphone with an interface of 3.5 mm, a circuit switching switch is added in the circuit of the earphone and between a micro anode wire and a ground wire of an original mobile phone earphone with a four-section plug, and therefore the micro anode wire and the ground wire of the earphone can be switched optionally. The earphone with a new structure can be suitable for electrical and electronic products with three-section or four-section circular-hole interfaces of 3.5 mm. Social resources can be fully utilized and waste is reduced. The earphone is energy-saving and environmentally-friendly.
Description
Technical field
The utility model relates to a kind of 3.5mm interface circular hole earphone.
Background technology
International standard is divided into two kinds to the 3.5MM circular hole earphone interface of mobile phone at present, a kind of is apple Samsung interface, another kind of Nokia interface, and two kinds are not general, numerous domestic producer chooses at random respectively again this two kinds of interfaces, so whole on the market handset earphone numerous and complicated especially; Other digital product such as MP3/CD and computer also use the interface of 3.5MM in addition, but fully not general with mobile phone again, and Mobile phone plug is 4 joints, and computer etc. are 3 joints.So there is not on the market general 3.5MM joint earphone, buy and all will divide model, buy use for production and selling and user, all bring too numerous and diverse problem, even often can buy wrong model and cause and can't use.Present some conversion products for subsequent use also having occurred on the market, such as universal mobile phone earphone conversion head, conversion line etc., but be not real ultimate solution, because all will add miscellaneous equipment, still can not adapt to all products simultaneously.
Summary of the invention
Technical problem to be solved in the utility model provides and a kind ofly is applicable to comprise the media digital products such as 3C communication and computer, and the 3.5mm interface circular hole earphone that uses of other electronic apparatus of the industries such as household electrical appliances and entertainment.
The utility model is achieved through the following technical solutions: a kind of 3.5mm interface circular hole earphone, comprise the earphone metallic plug, described earphone metallic plug comprises that L channel, R channel, ground wire and miaow are anodal, the setting arranged sequentially from top to bottom of described L channel, R channel, ground wire and miaow positive pole, the truncated position is serially connected with the circuit interswitch of six pin positions in the middle of described miaow positive pole and the ground wire, and described circuit interswitch is provided with a hands-free box outward.
As preferred technical scheme, described circuit interswitch can be the both positive and negative polarity diverter switch of universal mobile phone charger.
The beneficial effects of the utility model are: according to the line construction of 3.5MM interface handset earphone, the switch that in the middle of the circuit of earphone, adds a conversion line, adding the interchangeable switch of circuit between the miaow electrode line of the handset earphone of original 4 joint plugs and the ground wire, thus, miaow electrode line and the ground wire of earphone can arbitrarily exchange, the earphone product of this new construction just goes for all no matter be 3 joints or the electric equipment products of the 3.5MM circular hole of 4 nodel lines, it can allow social resources be fully utilized, cut the waste, save and environmental protection.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.
Fig. 1 is the overall structure schematic diagram of the utility model 3.5mm interface circular hole earphone.
Fig. 2 is the circuit structure diagram of the utility model 3.5mm interface circular hole earphone.
Embodiment
As depicted in figs. 1 and 2, a kind of 3.5mm interface circular hole earphone of the present utility model, comprise the earphone metallic plug, described earphone metallic plug comprises L channel 1, R channel 2, ground wire 3 and miaow positive pole 4, the setting arranged sequentially from top to bottom of described L channel 1, R channel 2, ground wire 3 and miaow positive pole 4, truncated positions are serially connected with the circuit interswitch 5 of six pin positions in the middle of described miaow anodal 4 and the ground wire 3, the described circuit interswitch 5 outer hands-free boxes 6 that are provided with.
Wherein, described circuit interswitch 5 can be the both positive and negative polarity diverter switch of universal mobile phone charger.
Line construction according to 3.5MM interface handset earphone, the switch that in the middle of the circuit of earphone, adds a conversion line, namely adding the interchangeable switch of circuit between the miaow electrode line of the handset earphone of original 4 joint plugs and the ground wire, thus, because the miaow electrode line of earphone and ground wire can arbitrarily exchange, so just having adapted to present all 3.5MM circular hole mobile phones uses, simultaneously, because the 3rd and the 4th joint of 4 joint plugs arbitrarily conversion wherein one saves as ground wire, also solved in the 3 joint earphones such as MP3/ computer the 3rd joint whole as ground wire, and after the 4 joint headset plugs insertions, because structural difference may cause these polar curves of ground wire of 4 joint handset earphones can't accurately touch the ground wire of 3 joint earphone jacks, thereby the realistic problem mostly can't use appears.The earphone product of this new construction just goes for all no matter be 3 joints or the electric equipment products of the 3.5MM circular hole of 4 nodel lines.
The above only be embodiment of the present utility model, but protection range of the present utility model is not limited to this, and any variation or replacement of expecting without creative work all should be encompassed within the protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range that claims were limited.
