Abstract
The utility model relates to a kind of headphone, and especially a kind of utilization vibrates the wear-type bone conduction earphone that touching, skin and bone are medium conducted acoustic waves.A kind of headphone, comprising: a set of headphones main body (two, left and right sound channel), neck formula across ear are worn, an auricular appendage plug; Described headset main body, comprises plastic casing, and shell surface comprises metal decorative sheet, and shell includes moving-coil type oscillator; Described oscillator, its moving-coil part is fixed on framework by playing ripple; Described neck formula is worn and is comprised metal spring; Described metal spring can be chip, line formula two type; Described earplug, comprises plastic buckle and soft plug, during non-usage, is fixed to neck formula and wears, during use, from the beginning put on and remove; Described headset main body, can comprise circuit, battery, as a active earphone, also can without circuit, battery, and as a Passive earphone.In the utility model, the stereo current signal of source of sound flows through voice coil loudspeaker voice coil, produces the electromagnetic force of an alternation, make to produce relative motion between voice coil loudspeaker voice coil and magnet, play ripple and produce distortion, and then, the vibration induced, by the skin of human body and osteoacusis, is directly transferred to auditory nerve sound wave.
Description
Art
The utility model relates to a kind of headphone, and especially a kind of utilization vibrates the wear-type bone conduction earphone that touching, skin and bone are medium conducted acoustic waves.
Background technology
Traditional headphone often utilizes electromagnetic force driven diaphragm to produce piston movement, sounds with air coupling.This sound, by the ear-drum of people, is transmitted to the auditory nerve of brain, and people call conductance type earphone this kind of earphone usually.Because conductance type earphone covers ear in use completely, thus user to all kinds of sound of surrounding enviroment, danger signal often without vigilance, this kind of earphone, to outdoor fan, also exists the birth defects that can not solve.In addition, conductance type earphone when with compared with high sound pressure, the ear-drum of user can be made to be in high-impact under always.Go down for a long time, certainly will ear-drum be damaged, cause the decline of hearing.In order to address this problem, bone conduction earphone has come out, and this earphone converts electrical signals to vibration signal, by contacting with the skin and bone of human body, as medium, sound wave is directly transferred to auditory nerve with solid (non-air).Owing to having the effect of protection ear-drum, bone conduction earphone, obtains the favor of people.But bone conduction earphone (mainly from Japan and Korea S) in the market, manufacturing process is complicated, and price is high, makes those interested clients hang back.In addition, its frequency band is narrow, poor definition, also has many places needing to improve.Further, when noise applications, the background noise of strong row often masks real signal content, causes user to be difficult to distinguish.
Summary of the invention
In order to overcome the shortcoming of traditional headphone, existing bone conduction earphone, the utility model provides that a kind of manufacture technology is simple, motor conversion efficiency is high, tonequality good, can shield the wear-type bone conduction earphone of background noise.
The technical solution adopted in the utility model is: the headband comprising headset main body and frames connecting with headphone main body; Described headset main body is made up of housing and the phonation unit be arranged on housing inner frame, phonation unit comprises the oscillator of circuit board and connecting circuit board, it is characterized in that described oscillator is moving-coil type oscillator, the voice coil loudspeaker voice coil on oscillator is fixed on the framework in housing by playing ripple.
In order to custom and the needs of the satisfied different consumer group, circuit board can be active circuit or passive circuit two kinds according to market demand by product, makes headset main body can comprise circuit, battery, as a active earphone, also can without circuit, battery, as a Passive earphone.
In order to the earplug be movably connected on headband can be arranged on headband, and making user comfortable, described headband is neck formula headband, and neck formula headband is provided with the elastomeric element of holding head banding pattern shape, described elastomeric element is made up of metal elastic part, and the type shape of metal elastic part is flap-type or line style two kinds.
In order to change the acoustics not affecting user when background noise is large, headband is provided with the earplug be movably connected on headband, described earplug by soft plug and be connected the buckle that soft plug connects and form, buckle there is active card be connected on bayonet socket on headband, during non-usage, be fixed to neck formula to wear, during use, from the beginning put on and remove.
In the design that the utility model discloses, the stereo current signal of source of sound flows through voice coil loudspeaker voice coil, produces the electromagnetic force of an alternation; make to produce relative motion between voice coil loudspeaker voice coil and magnet; play ripple and produce distortion, and then the vibration of inducing is by the skin of human body and osteoacusis; sound wave is directly transferred to auditory nerve; the utility model structure is simple, and cost is low, easy to use; in normal circumstances or can have when figure viewed from behind noise and normally use, acoustical quality is good.
Accompanying drawing explanation
Fig. 1 is the elastomeric element of the utility model headband is the structural representation of flap-type.
