Description
The present invention relates to a kind of personal earphone for language study, belong to the telecom technology field.Promptly being a kind of popular language learning instrument, is again stereophone.
Human physiology shows, the people is by the perception of ear to the spoken sounds of oneself, not depending merely on air to the conduction of sound but also rely on the resonance conduction that head skeleton produces when speech, promptly is not to resemble our common understanding-" listen " by air transmitted fully and arrive.Blocking ear with finger and talk, is exactly this reason according to the spoken sounds that just can hear oneself.As seen we transmit media by these two of head skeletons, air the common conduction of sound is come the sound of perception oneself, promptly we " listen " to own sound be a kind of " sound of combination " and hearer that we talk hears is " the single sound " that passes through transfer of air.These two kinds of sound are because of transmitting the difference of media, and its speech intonation also there are differences.We perceive ourselves the sound of oneself, the real sound of hearing with other people exists the difference on the speech intonation, and we are because the physiological structure of self can't remove to understand, be familiar with and experience the actual sound of oneself.In real life and communication, the obstacle of this communication usually brings inconvenience to us.Especially the study of foreign language language, on the foreign language voice, the difference of speech intonation causes the difference of the meaning especially easily and obscures.And the study of foreign language language can not have such language environment and the social environment of study mother tongue, when pronouncing, learning and mastering lacks the accumulation of comparison, contrast, feedback and experience, often cause cacoepy, and oneself can't be familiar with and be corrected consciously, the result is not easy accurately to grasp correct pronunciation and has become modal phenomenon in the foreign language language learning, directly has influence on the study of whole foreign language language.
Existing solution is that construction language learning classroom in school uses special-purpose language teaching equipment and earphone/microphone combination earphone special to carry out centralized language teaching.Language teaching equipment is a kind of special equipment that can play language learning audio tape teaching material and can be added to external voice signal to go in the source sound of playing, and two external jack interfaces are arranged, and one is that " microphone " is used to receive external voice signal; One is that " earphone " is used for mixed source sound is sent.Earphone/microphone combination earphone special has one and is talked about microphone, and uses two mono headset plugs, inserts first serial connection left and right acoustic channels earphone, " earphone " socket of corresponding language teaching equipment for these two; Microphone is talked about in a connection, " microphone " socket of corresponding language teaching equipment.In use two mono headset plugs of earphone are inserted into corresponding " earphone " on the language teaching equipment respectively, in " microphone " earphone socket, play language learning audio tape teaching material, at this moment the earphone wearer study of following the teaching material source sound just can be by the microphone of being talked about on the earphone of wearing with reading sound, import in the language teaching equipment and the source sound that is added to, conversion feeds back in its ear by air by its electroacoustic to pass the left and right acoustic channels earphone at last back, and making a kind of oneself can hearing in real time artificially mainly is oneself the academic environment of sound by transfer of air.The learner can as the hearer hear oneself actual sound like that, by just carrying out conscious pronunciation correction with the contrast of sound source RP, help accurately to grasp pronunciation, thereby play a kind of CAL effect of language learning, promote the teaching of foreign language language.
But, its rule of correct language learning be requirement carry out audition, pronunciation frequently whenever and wherever possible repeatedly, with exercise such as reading, and this centralized language learning that in the language learning classroom, utilizes the limited class hour that special equipment carries out, very incompatible and inconvenient for the language learning that need do the exercises repeatedly especially do not have this condition especially for the foreign language self-taught learner.
