Abstract
The utility model provides a kind of earphone based on osteoacusis, it includes osteoacusis duplex shake, digital signal processor, a/d converter and D/A converter, the osteoacusis duplex shake attached bag includes the first resonance end and the second resonance end, the first resonance end is connected by the a/d converter with the digital signal processor, the digital signal processor is connected by the D/A converter with the second resonance end, the first resonance end is arranged on described upper one end away from otica of osteoacusis duplex shake, the second resonance end is arranged on one end that otica is contacted on osteoacusis duplex shake.The earphone based on osteoacusis of the utility model can eliminate the noise jamming in the external world.
Description
Technical field
It the utility model is related to earphone field, more particularly to a kind of earphone based on osteoacusis.
Background technology
As social progress, scientific and technological development to us while more comfortable life is brought, us have also been brought
Undying noise, influence of the noise for people is also more and more prominent, and particularly when beautiful music is enjoyed, noise is done
Disturbing can allow people's mood unhappy often, or even people can be allowed to become more irritated.Noise refers to that pitch and loudness of a sound change are chaotic, has listened
Carry out disharmonic sound, produced by the irregular vibration of sounding body（It is different from " musical sound "）.
Also occur conducting the product for solving problems by gas on the market now, although there is certain effect,
It is or not ideal.Therefore, how to develop design a kind of can allow people no matter can pacify under what noisy environment
The quiet equipment for enjoying beautiful music, has become one and can not be ignored and technical barrier urgently to be resolved hurrily.
Utility model content
The purpose of this utility model is to provide a kind of earphone based on osteoacusis, is done so as to fulfill the noise for eliminating extraneous
Disturb, allow people no matter can the quiet beautiful music of enjoyment under what noisy environment.
Earphone provided by the utility model based on osteoacusis includes：Osteoacusis duplex shake, digital signal processor, AD
Converter and D/A converter, the osteoacusis duplex shake attached bag include the first resonance end and the second resonance end, the first resonance end
It is connected by the a/d converter with the digital signal processor, the digital signal processor passes through the D/A converter
It is connected with the second resonance end, the first resonance end is arranged on the one of the upper remote otica of osteoacusis duplex shake
End, the second resonance end are arranged on one end that otica is contacted on osteoacusis duplex shake.
In one embodiment of the utility model, the digital signal processor includes filter unit and rp unit,
The filter unit is used to be filtered the outside noise that collects, the rp unit be used to producing one with it is filtered
The opposite signal of noise phase.
Compared with prior art, the utility model uses osteoacusis mode, and directly by the vibration of oscillator, sound is believed
Number brain centres nerve is delivered to, eliminates the loudspeaker that traditional gas conduction needs, and can be allowed by way of osteoacusis
People feels more real sound, and using bone conduction technology, sound wave directly reaches auditory nerve by bone, it also avoid to people
Ear hearing produces injury；In addition, the vibration source of osteoacusis is a duplexing oscillator, which can either export vibration signal, again
Outside noise signal can be gathered；Eliminating traditional noise reduction needs to be used for the microphone sampled, and making an uproar by vibration acquisition
Acoustical signal is truer, allow people can in noisy environment can it is quiet, feel at ease, safety goes to enjoy truer, purer listen
Feel experience.
Brief description of the drawings
Fig. 1 is the structure diagram of the earphone based on osteoacusis of the utility model.
Embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, is further elaborated the utility model.It should be appreciated that specific embodiment described herein is only explaining
The utility model, is not used to limit the utility model.
The structure of the utility model is described in detail below in conjunction with specific embodiment.
As shown in Figure 1, a kind of earphone based on osteoacusis provided by the utility model includes osteoacusis duplex oscillator 10, number
Word signal processor 20, a/d converter 30 and D/A converter 40.
The osteoacusis duplex oscillator 10, including for gathering the first resonance end 11 of extraneous noise and for exporting sound
Second resonance end 12 of the frequency signal to human ear.The first resonance end 11 is arranged on the osteoacusis duplex oscillator 10 away from ear
One end of bone, the second resonance end 12 are arranged on one end that otica is contacted on the osteoacusis duplex oscillator 10.
The digital signal processor 20, the outside noise for being collected to the first resonance end 11 are handled,
And one is exported with the vibration signal of the outside noise opposite in phase to the second resonance end 12.As shown in Figure 1, the number
Word signal processor 20 includes filter unit and rp unit, and the filter unit is used to filter the outside noise collected
Ripple, the rp unit are used to produce a signal opposite with filtered noise phase.
The a/d converter 30, is arranged between the osteoacusis duplex oscillator 10 and the digital signal processor 20,
Outside noise for the first resonance end 11 to be collected is converted into digital signal and is sent to the Digital Signal Processing
Device 20.
The D/A converter 40, is arranged between the osteoacusis duplex oscillator 10 and the digital signal processor 20,
The signal opposite with noise phase for the digital signal processor 20 to be exported is converted into analog signal and is sent to institute
State the second resonance end 12.
In conclusion the utility model uses osteoacusis mode, directly by the vibration of oscillator, voice signal is delivered to
Brain centres nerve, eliminates the loudspeaker that traditional gas conduction needs, and people can be allowed to feel by way of osteoacusis
More real sound, using bone conduction technology, sound wave directly reaches auditory nerve by bone, it also avoid producing human ear hearing
Raw injury；In addition, the vibration source of osteoacusis is a duplexing oscillator, which can either export vibration signal, and can gather
Outside noise signal；Eliminating traditional noise reduction needs to be used for the microphone sampled, and by the noise signal of vibration acquisition more
Add it is true, allow people can in noisy environment can it is quiet, feel at ease, safety removes to enjoy truer, purer audio experience.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
