Abstract
The utility model relates to a health-protection type wide frequency ear-phone, which is composed of an earphone core, a conductor and a plug, wherein, the earphone core and the plug are respectively connected with both ends of the conductor, and the health-protection type wide frequency ear-phone is provided with a wire collecting box. The utility model is characterized in that the health-protection type wide frequency ear-phone is provided with an ear-support, and the earphone is fixed to the center position of the ear-phone. The ear-support is a semi-circle ring form, and the earphone core selects moving-coil type single side wide frequency earphone core. The utility model has the advantages of beautiful appearance, novel structure, small size, light weight and comfort and convenience, and can be used in TV sets, receivers, hearing aids and important conference equipment; compared with the traditional earphones, the health-protection type wide frequency ear-phone has wide frequency band, small distortion, big power and good tone quality.
Description
The utility model relates to a kind of health wideband supra-aural earphone, is a kind of supra-aural electroacoustic transducer.
Existing earphone generally can be divided into two kinds of ear type and headring formulas, is made up of earphone, lead and plug, and insert earphone in use easily makes the row pond thing in the duct enter the earplug hole, and often use can cause the duct disease, and in use uncomfortable, and the foreign matter sensation is arranged.Headring formula earphone is airtight, and long-time use not only influences hearing, also can make the people produce phenomenons such as dizziness, tinnitus, is unfavorable for physical and mental health.In addition, existing earphone does not mostly have take-up, if the earphone lead is long, needs during use lead is made in order, does not note slightly, will random line, and time-consuming bothersome, both be not easy to deposit, be difficult to again during use untie, even can form fast knot, influence earphone useful life.Secondly existing insert earphone frequency band is narrow, and distortion is big, and lower tone is difficult to satisfy the culture life demand that people improve constantly.
The utility model provides a kind of health wideband supra-aural earphone, adopt the supra-aural structure, select the monolateral wideband earphone of moving-coil type core for use, bandwidth, distortion is little, tonequality is graceful, easy to use comfortable, having avoided insert earphone to bring various illness and uncomfortable sensation for people's ear, is a kind of desired electrical sonic transducer spare for individual or many people audition, is widely used in the transaudient device in television set, broadcast receiver, hearing aids and the conference facility.
Design philosophy of the present utility model is: health wideband supra-aural earphone, adopt the supra-aural structure to replace ear type of the prior art and headring formula structure, select the monolateral wideband earphone of moving-coil type core for use, increase winding box, overcome existing insert earphone and headring formula earphone defective, for people provide a kind of comparatively desirable Novel earphone.
Design of the present utility model is: health wideband supra-aural earphone is made up of earphone core 2, lead 3, plug 4, earphone core 2, plug 4 are connected to the two ends of lead 3, be provided with a supra-aural support 1, make earphone core 2 be fixed on the centre position of supra-aural support 1.
Supra-aural support 1 is shaped as semi-round ring shape, position is provided with the fixing hole of fixed earphone core 2 in the middle of it, what earphone core 2 was selected for use is the monolateral wideband earphone of moving-coil type core, during use, plug in 4, half garden annular supra-aural support 1 is hung over the ear outside, then earphone core 2 is positioned at outside people's ear earhole, Energy and comfort, and do not influence work, study and exercise.
Secondly, be provided with winding box 7, easily at random when needing lead longer to solve some earphone, the problem of knotting, such as the earphone that aims at the television set design, its conductor length is about 3.5m, just is furnished with winding box 7, winding box 7 is by lid 5,6 constitute at the bottom of the box, lid 5 inboards are shaped on hollow roll 8, its center is hinged at the bottom of the box on 6 centers by pin, lid 5 outsides are shaped on groove, 6 one sides all are shaped on the inlet wire groove at the bottom of reaching roll 8 one sides and box on the lid 5, make supra-aural support 1 be arranged in groove, earphone core 2 is positioned at hollow roll 8, lead 3 is arranged in the inlet wire groove, at this moment, rotates lid 5 by hand, then lead 3 just is wrapped on the hollow roll 8, when using earphone, plug in 4,6 to correct position at the bottom of the user holds the winding box box, then lead 3 is unwound to certain-length, take off earphone the groove from lid 5 and be suspended on the ear and can use this moment, after using earphone is placed in the groove on the lid 5, rotates lid 5 by hand, can the folding and unfolding of earphone lead is good, take-up, unwrapping wire, use all easily, not random line is not tied a knot.
The utility model compared with prior art, adopt the supra-aural structure, novel structure, good looking appearance, volume is little, in light weight, comfortable wearing convenient, has avoided contacting of earphone and duct, ventilative, clean, sanitary, the earphone core is selected the moving monolateral wideband earphone of rolling core for use, and bandwidth, distortion is little, power is big, tonequality is graceful, and transient response is good, in addition, be provided with winding box, solved problem easily at random when the earphone lead is long, knotting, and take-up, unwrapping wire be convenient and swift.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation that the utility model is furnished with winding box.
Embodiment: with reference to specification the 5th part and accompanying drawing 1,2, supra-aural support of the present utility model can be selected moulding or bakelite spare for use, lead, plug buyable general part, earphone core buyable or external coordination solve, assemble then, test, can produce finished product towards magnetic, winding box can be selected moulding or bakelite spare for use, the utility model can form plurality of specifications according to impedance magnitude and conductor length, be that impedance is 4 Ω, 8 Ω, 16 Ω, 32 Ω, conductor length 1m～3.5m, through preliminary test, the utility model important technological parameters is:
Frequency range: 20～20000Hz
Sensitivity: 〉=95DB/mw(1000Hz)
Power: 〉=0.1W
Weight: 10.3g
