Description
Technical field
The utility model is related to intelligent wearable device technical field, particularly a kind of neck wears formula interactive voice earphone.
Background technology
Development and people's living standards continue to improve with intelligent wearable device, various intelligent wearable devices such as intelligence
The use of wrist-watch is more and more universal, and intelligent wearable device has become indispensable means of communication in people's life.
Why people can hear sound, be that vibration is transmitted to ear-drum by external ear duct because of the vibrations in air,
Pass through the auditory nerve for the vibratory drive people that ear-drum is formed.And when the middle external ear of people damages or clogs duct with hand, sound
It also is able to transmit acoustical vibration by the skin and bone of people, to drive the auditory nerve of people.
Osteoacusis is a kind of sound conduction mode, passes through the skull of people, temporal bone, osseous labyrinth, the transmission of inner ear lymph, ear
Snail, auditory nerve, auditory center transmit sound wave, and here it is bone conduction technologies.Osteoacusis is to vibrate skull or temporal bone, obstructed
External ear is crossed to be transmitted directly in inner ear with middle ear.Relative to traditional air transmitted side that sound wave is generated by Loudspeaker diaphragm
Formula, osteoacusis eliminate the step of many sound waves transmit, clearly sound-reducing, and sound wave can be realized in noisy caliber
Her people will not be influenced because of spreading in air.
However, bone conduction technology also have the shortcomings that it is following：(1) the appropriate position with contacting bone of bond-conduction sound
Correlation, it is also related with the feature of tissue.Such as：The difference such as age of user, gender, fat or thin can all cause different user to exist
During using same bone conduction earphone, there is different experience, often this different experience is all penalty.(2) it is passed using bone
Waveguide technology is called or send words, and bone conduction device must be close to bone, and Shen Bo directly reaches auditory nerve, wearing side by bone
Formula determines that bone conduction device must oppress bone conduction device height and is passed on bone that some absent-mindedness will influence sound
Keep pouring in the quality passed, however the wearing mode of this height compressing bone causes user's comfort in use, skin
Health is influenced to different extents.(3) bone and tissue generate the amplitude with frequency selectivity for refreshing Eastcom number
The audio signal in attenuation and delay, high-fidelity or broadband is difficult to auditory nerve, so based on existing skill by bone conduction
User's majority of art can complain that bone conduction earphone " sound quality " and " timbre " are poor.(4) the problem of osteoacusis leakage sound.Because solid-state is conducted
The characteristic of vibration, most existing bone conduction technologies all can not really solve the problems, such as that osteoacusis leaks sound, this is because the prior art
The reality of the skeleton of frequency dependence and tissue attenuation vibration signal is compensated by big volume, big vibration signal,
That is that this method is equivalent to and drinks poison to quench thirst, and user can complain that leakage sound is serious or since it is desired that the power of bigger, osteoacusis are loyal
Sub-volume weight greatly increases, and causes equipment whole excessively heavy.(5) bone conduction earphone is the system of open ears, works as user
It stays in a noisy environment, since the opening of bone conduction earphone can cause user to can't hear the sound transmitted in earphone at all
Sound.
Patent application application No. is 102084668A discloses the method and system of processing signal, the system comprises：
(a) processor is set as handling and carves the first input signal detected when detecting by the first microphone, existed by second microphone
The second input signal and carve the third input signal detected when detecting by the first microphone that detection moment detects,
To generate in response to the signal after the correction of first, second, and third input signal；And (b) communication interface, be set as to
External system provides the signal after correction.This method carries out noise reduction process by convolution function to sound, and it is more accurate to have obtained
Voice signal.But due to being that a few road sound mix, some sound are easily mistaken for correct sound and are recorded in track
In, therefore the sound exported is not entirely accurate and clearly.
Patent application application No. is 105721973A discloses a kind of bone conduction earphone and its audio-frequency processing method, wherein
A kind of bone conduction earphone and its audio playing apparatus based on the bone conduction earphone, the bone conduction earphone include skeleton
With tissue model modeling module and mathematics presetter, Delay computation unit, digital analog converter, analog-digital converter, first
Low-pass filter, the second low-pass filter, audio-frequency amplifier, audio drive amplifiers, at least one first microphone, at least one
A bone conduction vibrator；The attenuation effect information of the skeleton of monitoring different user and tissue in real time, based on the attenuation effect
Information generates a compensation transmission function, and input audio signal carries out input audio signal by the compensation transmission function
It is conducted in bone and tissue after digital pre-calibration.The application is to carry out pre- school to the audio of input by the method for compensation
Just, but this method be mainly used for solve audio signal attenuation problem, correct audio can not be told from noise
Data.
