Abstract
The invention discloses an auditory meatus microphone and a device with the auditory meatus microphone, and relates to the voice communication technology. A voice wire section A between the auditory meatus microphone and an ear frame is a soft connection wire section. When the auditory meatus microphone is worn, environment noise can not be led into due to the fact that the auditory meatus microphone retreats from the auditory meatus by itself, special requirements for the materials and the diameter of an isolation noise reduction sleeve do not exist, noise can not be generated when the head of a wearer rotates or other parts of the body vibrate, words of voice signals collected by the auditory meatus microphone are clear and accurate, and the auditory meatus microphone and the device with the auditory meatus microphone are particularly suitable for intelligent voice control, synchronous translation of a translation cloud system and voice communication in the strong noise environment.
Description
Technical field
The present invention relates to a kind of duct microphone and operative installations thereof.
Background technology
Although the angle from software engineering, although Voice search engine has had powerful keyword search or resolution capability, even can identify multiple slang, dialect, but owing to there is no to pick noiseless microphone upstream key equipment, to such an extent as to the speech-sound intelligent technology can only rest on wrong toy or the game epoch that rebegin for many years, can only rest on conceptively, can't advance practical application.
Microphone is as a kind of transducer of realizing sound wave is changed into the signal of telecommunication, and its technology is quite ripe, the brilliant formula of the common electret capacitor type of version, moving-coil type and carbon etc.The remarkable shortcoming of prior art microphone is first to pick the voice signal that includes environmental noise, and then noise signal is carried out to noise abatement or noise reduction process.Its noise abatement or noise-reduction method are: multi-angle is arranged a plurality of pick-ups, directly to offset or to be overcome environmental noise by software engineering.
The microphone of prior art carries out the remedial measure of noise reduction or noise abatement to the noise of first picking, the effect of its noise abatement or noise reduction, only can be satisfied with in more quiet environment, the demand of the brain judgement voice call content of employment, can not meet search and the judgement to keyword of computer or other smart machine Voice search engine fully, and the demand of the voice call in strong background noise.That is to say, noise abatement or noise reduction microphone by prior art, if the user be in as travel in the locomotive driving cabin in, the road of locomotive driving is arranged, someone speaks, has the environment that the Workplace etc. of noise is made a lot of noise by the side of, the voice signal that its microphone is picked, just can not be as the signal source of computer or other smart machine Voice search engine, otherwise computer or other smart machine can be done the judgement made mistake and maybe can not identify keyword; Also can not realize interpersonal speech communication in naval vessel, submarine, tank, panzer and in other noisy environment.
For fear of gathering environmental noise, occurred that already ear pastes the bone-conduction microphone that skin is used outward.Although bone-conduction microphone does not gather environmental noise, speaker's voice ambiguous of its collection, control to such an extent as to can not be applied to intelligent sound fully.
Notification number is CN2744099's " can insert human ear's microphone apparatus " microphone of disclosing, wear end user's head without rotate or the prerequisite of other position friction of health, twisting under, pick-up does not only gather environmental noise in theory, the speaker's voice signal only gathered, should meet the demand that intelligent sound is controlled, but still there is following unsurmountable shortcoming in this patent, and these shortcomings make it not have practical value fully:
One, its accompanying drawing is expressed is designed to full-closed structure, in the industry manufacture, can not realize.Improve the possibility that this structure makes it to have realization, it must be split as at least three elements: collection sound path, pick-up, housing, the three is indispensable.Structure after fractionation is complicated, have redundant component.
Its two, the diameter of the external end head of microphone is much larger than barrel diameter, the sound wave of the environmental noise that ear is outer will cause certain impulsive force to external end head, thereby introduce environmental noise.
Its three, this duct microphone apparatus, in use necessarily require to wear end user's head without rotating or other position friction of health, twisting static, but these conditions are non-existent in practicality.Because wearing head rotation or other position twisting of health of end user is objective reality, the shake of long voice wire or gas-guide pipeline, vibration are enough to cause pick-up to introduce dither noise.
In other words, the microphone that " can insert human ear's microphone apparatus " of notification number CN2744099 disclosed can not be obtained noiseless voice signal in duct, does not reach purpose of design.
Ben, the reason that the above-mentioned duct microphone that affects prior art practices effect is recessive, to such an extent as to still lose so far practical duct microphone.Before the present invention, people do not recognize the true cause of duct microphone generating noise or find its not enough method that overcomes, prior art developer is mainly for the ear canal diameter size of different people, the isolation noise reduction cover of design different-diameter, and attempt by screening the complicated means such as isolation noise reduction cover material of different pliabilitys, to obtaining the best structural design of wearing effect, thereby reach the purpose that obtains best sound effect.However, the duct microphone of prior art still can not be adapted to the broad-spectrum demand of the individual difference of numerous end users' of wearing various ears and duct structure, make the duct microphone of prior art be difficult to really overcome environmental noise, thereby meeting intelligent sound, acquisition controls the needed pure voice signal of the cloud translation on line system of translating especially combined with the Internet.
Summary of the invention
First purpose of the present invention just is to provide a kind of ambient noise that do not gather, only gather the speaker because of vocal cord vibration the eardrum caused by osteoacusis or and duct vibrate to reduce the duct microphone of voice signal, provide can meet computer or other smart machine for Voice search engine the voice signal to the requirement of the requirement of keyword degree of purity and strong noisy environment person to person speech communication clearly.
Second purpose of the present invention just is to provide a kind of simple in structure, wear use the MEC microphone can not exit voluntarily duct, to isolation noise reduction cover material and diameter all without specific (special) requirements, wear end user's head rotation or the vibration of health other parts can not cause introducing noise yet, can provide meet fully computer or other smart machine for Voice search engine to the requirement of keyword degree of purity, and the duct microphone operative installations of the voice signal that in strong noisy environment, person to person's speech communication requires.
