Description
Technical field
The utility model relates to the earphone used as audio frequency apparatus, specifically, relates to a kind of general electro-acoustic element earphone of adjusting sound volume.
Background technology
Along with the development of society and the continuous progress of science and technology, electronic product is invariably towards the trend development of skilful miniaturization, no matter but be which kind of electronic product relevant with sound, the acoustic information listened to electronic product to allow user under the situation not disturbing other people and provide, earphone, as a kind of Personal loudspeaker box baffle, has become the necessary accessory of electronic product.
At present, the earphone interface standard of the terminal equipments such as computer general in the world, mobile phone, media player has two, and one is the standard of OMTP, and one is the standard of CTIA.In general, international manufacturer major part uses CTIA standard, and the product of domestic manufacturers then needs to support OMTP standard.For the Earphone joint of OMTP standard and CTIA standard, on plug from tip, first paragraph is the same with the definition of second segment, connect L channel and R channel respectively, the main distinction is the definition of third and fourth section, and the definition of CTIA standard is followed successively by ground wire (GND) and microphone/control loop, and the definition of OMTP standard is just in time contrary, 3rd section is microphone/control loop, and the 4th section is ground wire/signal circuit.When terminal earphone jack definition and headset plug define inconsistent time, there will be the problem that earphone cannot normally use, make earphone not possess versatility.
Utility model content
Problem to be solved in the utility model overcomes the deficiencies in the prior art, provides a kind of and can be applicable to the general electro-acoustic element earphone that CTIA standard can be applicable to again the adjusting sound volume of OMTP standard.
For solving the problem, the technical solution adopted in the utility model is: a kind of general electro-acoustic element earphone of adjusting sound volume, comprise headset plug, wire, receiver and volume adjustment device, described headset plug connects one end of wire, and described receiver connects the other end of wire, and described volume adjustment device is arranged on wire, and be electrically connected with wire, described headset plug comprises two, and one adopts OMTP standard, and one adopts CTIA standard; Suit one spring is fixed at described headset earpiece place.
Preferably, described conductive line surfaces is set with the overcoat of a telescopic folding.
Preferably, described volume adjustment device adopts duplex potentiometer.
The beneficial effects of the utility model are: conductor wire end connects two headset plugs, and two headset plugs adopt different technical standards separately, the use in different technologies standard device of an earphone can be realized, decrease unnecessary expenditures, be conducive to energy-conserving and environment-protective; Volume adjustment device on wire, according to the difference of external condition, can regulate at any time; Fix suit one spring at headset earpiece place, because earphone occurs broken string through headphone of being everlasting, and fix suit one spring at headset earpiece place, effectively can avoid this situation, thus when bending, be arc, extends the useful life of earphone; Be set with the overcoat of a telescopic folding in conductive line surfaces, overcoat can be stretched out when wire launches, so can effectively avoid wire to knot, easy to usely also to increase the service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark in figure:
1, headset plug; 2, wire; 3, receiver; 4, volume adjustment device; 5, spring; 6, overcoat.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
A kind of general electro-acoustic element earphone of adjusting sound volume, comprise headset plug 1, wire 2, receiver 3 and volume adjustment device 4, described headset plug 1 connects one end of wire 2, described receiver 3 connects the other end of wire 2, described volume adjustment device 4 is arranged on wire 2, described headset plug 1 comprises two, and one adopts OMTP standard, and one adopts CTIA standard; Suit one spring 5 is fixed at described headset earpiece 3 place.
Preferably, the overcoat 6 of described wire 2 surface suit one telescopic folding.
Preferably, described volume adjustment device 4 adopts duplex potentiometer.
The beneficial effects of the utility model are: wire 2 end connects two headset plugs 1, and two headset plugs 1 adopt different technical standards separately, the use in different technologies standard device of an earphone can be realized, decrease unnecessary expenditures, be conducive to energy-conserving and environment-protective; Volume adjustment device 4 on wire 2, according to the difference of external condition, can regulate at any time; Fix suit one spring 5 at headset earpiece 3 place, because earphone occurs broken string through receiver 3 place that is everlasting, and fix suit one spring 5 at headset earpiece 3 place, effectively can avoid this situation, thus when bending, be arc, extends the useful life of earphone; At the overcoat 6 of wire 2 surface suit one telescopic folding, overcoat 6 can be stretched out when wire 2 launches, so can effectively avoid wire 2 to knot, easy to usely also to increase the service life.
The above is only preferred embodiment of the present utility model, is not restriction the utility model being made to other form.Any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the Equivalent embodiments of equivalent variations.But everyly do not depart from technical solutions of the utility model content, any simple modification, equivalent variations and the remodeling done above embodiment according to structure of the present utility model and operation principle, still belong to the protection range of technical solutions of the utility model.
