Abstract
The utility model provides an MP3 which belongs to the technical field of a memory. The utility model settles the following problems in the prior MP3: earphone wire knotting caused by easy scattering of the earphone wire from a player because of no structure for restraining the earphone wire, inconvenient use, etc. The MP3 comprises a disc-shaped housing and an annular sleeve. The housing is provided in the sleeve and can rotate around an axis relative to the sleeve. The sleeve is provided with a gap of which the radian is smaller than 180 DEG. The circumferential surface of the housing is provided with a first annular groove, and the groove wall of the first annular groove is provided with an earphone jack. The MP3 provided by the utility model is advantageous in that: when the MP3 is not in use, the housing can be rotated for winding the earphone wire in the first annular groove; the earphone wire does not come out of the first annular groove; and knotting of the earphone wire is prevented.
Description
Technical field
The utility model belongs to the memory technology field, relates to a kind of MP3.
Background technology
MP3 is very common pastime articles for use in daily life, MP3 mainly is comprised of player and earphone, progress along with science and technology, the player of MP3 is more and smaller and more exquisite by what do, greatly facilitate carrying of people, and earphone is also little due to the needs variation of structure and function, all by earphone cord, with player, is connected.Present MP3 is all to the constraint structure of earphone cord,, often not using at random being wrapped on player of earphone cord, owing to not fettering earphone cord, is easy to be scattered and cause the situation of earphone cord knotting from player, is inconvenient to use.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of MP3, and this MP3 has the characteristics that hold onto earphone cord that can be neat.
The purpose of this utility model can realize by following technical proposal: a kind of MP3, it is characterized in that, comprise the overcoat that is discoidal housing and is annular, described housing is positioned at overcoat, described housing can rotate relative to overcoat around axis, described outer putting offers radian less than the breach of 180 °, and the side face of described housing offers annular groove one, offers receiver J-Horner on the cell wall of described annular groove one.
Earphone is inserted in receiver J-Horner and is connected with MP3, because housing can rotate, therefore can roll-shell when not using MP3 with earphone cord from being wound in annular groove one, earphone cord can be from the interior disengaging of annular groove one, the assurance earphone cord can not tied a knot, earphone cord is received in annular groove one does not simultaneously affect the outward appearance of MP3, and easily carries; Pull earphone cord can drive housing during use and rotate around overcoat, thereby earphone cord is pulled out from the indentation, there of overcoat, convenient to use.
In above-mentioned MP3, the edge at the two ends of described housing all offers the step of annular, and the medial surface of described overcoat offers annular groove two, the both sides cell wall of described annular groove two respectively with the step at the two ends of housing against.The cell wall of housing by step and annular groove two is against being positioned in overcoat, and annular groove two has increased the space in overcoat and annular groove one, guarantees earphone cord is all accepted.
In above-mentioned MP3, the cell wall of described annular groove two and above-mentioned step are tight fit.Tight fit makes overcoat and housing keep fixing while can or not pull earphone cord at section's roll-shell, and can keep the earphone cord of certain-length to be positioned at outside annular groove one, can not be subject in use the long puzzlement of earphone cord.
In above-mentioned MP3, the lateral surface of described overcoat is arc surface.
In above-mentioned MP3, the cross section of described annular groove one is rectangular, and the cross section of described annular groove two is circular arc.The cross section of annular groove one is rectangular can prevent that earphone cord is from the interior disengaging of annular groove one.
In above-mentioned MP3, be fixed with display screen on the end face of an end of described housing.Conveniently check the playback of songs situation.
Prior art is compared, and this MP3 has the following advantages:
Can roll-shell while 1, not using MP3 with earphone cord from being wound in annular groove one, earphone cord can be from the interior disengaging of annular groove one, guarantees that earphone cord can not tie a knot, earphone cord is received the outward appearance that does not affect MP3 at annular groove one simultaneously, and easily carries;
Pull earphone cord can drive housing while 2, using MP3 and rotate around overcoat, thereby earphone cord is pulled out from the indentation, there of overcoat, convenient and swift.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure, 1, housing; 12, receiver J-Horner; 13, step; 14, annular groove one; 15, display screen; 2, overcoat; 21, annular groove two; 22, breach.
Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
as shown in Figure 1, a kind of MP3, comprise the overcoat 2 that is discoidal housing 1 and is annular, the lateral surface of overcoat 2 is arc surface, one end of housing 1 is fixed with display screen 15, housing 1 is positioned at overcoat 2, housing 1 can rotate relative to overcoat 2 around axis, offer radian on overcoat 2 less than the breach 22 of 180 °, prevent that overcoat 2 and housing 1 break away from, in the present embodiment, the radian of breach 22 is 90 °, the side face of housing 1 offers annular groove 1, the cross section of annular groove 1 is rectangular, can prevent that earphone cord is from the interior disengaging of annular groove 1, offer receiver J-Horner 12 on the cell wall of annular groove 1.
As shown in Figure 1, the edge at the two ends of housing 1 all offers the step 13 of annular, the medial surface of overcoat 2 offers annular groove 2 21, the both sides cell wall of annular groove 2 21 respectively with the step 13 at the two ends of housing 1 against, the cross section of annular groove 2 21 is circular arc.The cell wall of housing 1 by step 13 and annular groove 2 21 be against being positioned in overcoat 2, and annular groove 2 21 has increased the space in overcoat 2 and annular groove 1, guarantees earphone cord is all accepted.The cell wall of annular groove 2 21 and step 13 are tight fit.Tight fit makes overcoat 2 and housing 1 keep fixing while can or not pull earphone cord at section's roll-shell 1, and can keep the earphone cord of certain-length to be positioned at outside annular groove 1, can not be subject in use the long puzzlement of earphone cord.
Earphone is inserted in receiver J-Horner 12 and is connected with MP3, because housing 1 can rotate, therefore can roll-shell 1 when not using MP3 with earphone cord from being wound in annular groove 1, earphone cord can be from the interior disengaging of annular groove 1, the assurance earphone cord can not tied a knot, earphone cord is received the outward appearance that does not affect MP3 at annular groove 1 simultaneously, and easily carries; Pull earphone cord can drive housing 1 during use and rotate around overcoat 2, thereby earphone cord is pulled out from the breach 22 of overcoat 2, convenient to use.
