Abstract
The utility model discloses an ear microphone and a use device thereof, and relates to a voice communication technology. A section A of a voice lead between an ear microphone body and an ear rack is a flexible connecting segment. The ear microphone body does not automatically retreat from an ear track, resulting in introducing of ambient noise when being put on; the ear microphone does not have special requirements on the material and the diameter of an insulation and noise-reduction sleeve; no noise is generated even if the head of a wearer rotates or other parts of the body vibrate; a voice signal collected by the ear microphone is clear and accurate in words. Therefore, the ear microphone is especially applicable to intelligent voice control and simultaneous translation of a yiyun (Chinese character) system, and voice communication in a serious noise environment.
Description
Technical field
The utility model 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 speech-sound intelligent technology can only rest on wrong toy or the game epoch that rebegin for many years, can only rest on conceptively, cannot advance practical application.
Microphone is as a kind of transducer that sound wave is changed into the signal of telecommunication of realizing, 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 computer or other smart machine Voice search engine completely to the search of keyword and judgement, 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 user be in as travel in locomotive driving cabin in, have the road of locomotive driving, someone speaks, has the noisy environment such as Workplace 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 making 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, controls to such an extent as to can not be applied to intelligent sound completely.
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 gathering, should meet the demand that intelligent sound is controlled, but still there is following unsurmountable shortcoming in this patent, these shortcomings do not have practical value it completely:
One, its accompanying drawing is expressed is designed to full-closed structure, in industry manufacture, can not realize.Improve the possibility that this structure makes it to have realization, must be split as at least three elements: collection sound path, pick-up, housing, 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 outside ear will cause certain impulsive force to external end head, thereby introduces 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 is 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 loses so far practical duct microphone.Before the utility model, 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 object that obtains best sound effect.However, the duct microphone of prior art still can not be adapted to the broad-spectrum demand of numerous end users' of wearing various ears and the individual difference of 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 combining with the Internet.
