Abstract
The utility model discloses an ear hanging MP3, including a machine body which is provided with a display screen, a control and a keystroke on surface and an MP3 cassette mechanism and a power source inside. The utility model is characterized in that a pair of earphones attached to the machine and a pair of ear hooks are arranged on the machine body. The utility model combines the present ear hanging earphones with a small MP3, thus saves an earphone wire and an MP3 shell, and improves the cavity of the earphone shells so as to place the cassette mechanism of the MP3 and the power source, hence the machine becomes smaller. As the earphones are hanged on the ears through the hooks and the loudspeaker is at the earlaps, the sound is not only sent into the ears but also spread to other directions, hereby, the negative impact of the earphones on the ears is reduced.
Description
Technical field
The utility model relates to a kind of MP3.
Background technology
At present, MP3 on the market is of a great variety, and pattern is different.But can be divided into two classes substantially, head-type MP3 and ear are inserted formula MP3.On the market the sort of bulky is with overhead earphone-type MP3, belongs to the first kind, and connects MP3 and interior aural headphone by earphone cord, realizes what voice signal was play, is called ear to insert formula MP3, then belongs to second class.The kind of existing MP3 all respectively has its weak point, huge head-type MP3 earphone, and outward appearance is too big, not attractive in appearance after being with, and can't use the summer in sweltering heat especially, is not fit to modern youthful requirement, so Xiang Guan product is not a lot of on the market.The MP3 that now accounts for main flow on market still is that ear is inserted formula, its very tangible weak point is exactly that long earphone cord, no matter we are when walking or when work (not influencing under the prerequisite of work), that long earphone cord all can bring unusual inconvenience to us.
Also have one unnoticed be again very severe problem, be exactly that ear is inserted formula MP3 people's hearing is had certain influence." use the improper hearing that may destroy a generation of MP3 ", the research conclusion that U.S. scientist announces is just being understood this saying once more.Studies show that; the inner ear formula earplug that is taken as many walkmans use standards at present can increase the risk of people's hearing impairment; when using inner ear formula earplug to listen big music; time should be limited in and add up every day to be no more than 90 minutes; just can avoid damaging ear; listen to the music above 5 minutes with the volume of maximum; then may cause permanent injury of ear; the researchist investigates discovery to 100 students; those tonequality are relatively poor; effectively the earphone of shielding noise can make the people improve volume unintentionally usually, and then hearing is caused long-term influence.The relevant expert thinks that the process of hearing disability is very slow, needs just can manifest in 10 years.Interior aural headphone to the reason that hearing works the mischief is, its position is on the duct mouth of inner ear, though guaranteed not disturbed by outside sound, the sound of earphone also can't be overflowed to the external world, strengthened the hearing burden of ear.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, provides a kind of volume little, can break away from the constraint of earphone cord, to the little supra-aural MP3 of hearing influence.
Realize that the technical scheme that the utility model purpose adopts is: supra-aural MP3 comprises a fuselage, and fuselage is provided with earphone, display screen, control button and ear-hang hook, and MP3 movement and power supply are housed in the fuselage.
In the described technical scheme, the control button can be located at the back side or the side of fuselage, be located at the front of fuselage with earphone.
In the described technical scheme, USB interface can be set on fuselage, also have the charging of battery with realization and company's machine of computer.
Another technical scheme that the utility model adopts is: described supra-aural MP3 also comprises a supporting earphone, and supporting earphone is provided with the ear-hang hook, is electrically connected by lead between MP3 fuselage and the supporting earphone, and the length of lead is just being to be advisable after striding across neck.
In the technical program, power supply can be placed in the MP3 fuselage, also can be placed in the supporting earphone.
In the technical program, the MP3 fuselage can be fixedlyed connected with the side connecting conductor formula between the supporting earphone, or the flexible connection of plug-in type.
Further technical scheme is, can load onto transmitting set and power supply in the MP3 fuselage, loads onto power supply, power switch, radio receiver in supporting earphone, replaces wired connection, realizes the wireless connections of MP3 fuselage and supporting earphone.
In the technical program, can on supporting earphone, charging inlet be set, to realize the charging of battery in the supporting earphone, be provided with the wireless signal that antenna assembly receives the emission of MP3 fuselage.
The utility model makes up with existing supra-aural earphone and small-sized MP3, can save the shell of earphone cord and MP3, is improved to place movement and the power supply of MP3 with the inner chamber of earphone outer covering, makes its miniaturization.Because this kind earphone is by hook, hang on the ear, its loudspeaker position is in the external ear place, so sound except propagating in ear, also has part to escape, can reduce earphone to ill effect that ear produced.
Further specify the technical solution of the utility model below in conjunction with accompanying drawing.
