Abstract
The utility model relates to a computer language learning machine. The computer language learning machine uses a pair of steady-state control circuits to control the operating statuses of the motor drive control circuit and the language recording-playback circuit of a magnetic tape recording-playback machine. Therefore, the language recording-playback circuit realizes to automatically cycle the pick-up signals of a microphone and the playback signals of a magnetic tape or automatically output recording signals to a loudspeaker. Therefore, the computer language learning machine provides the functions of repetition, reading following, comparison and outside recording, and the functions are needed when people learn languages. The utility model has the advantages of simple structure, reliable performance, convenient operation and good sound quality and has the functions of repetition, optional comparison and reading following and automatic cycling recording simultaneously. The computer language learning machine is a good assisting tool for people to learn languages.
Description
The utility model relates to a kind of language learning servicing unit, and refering in particular to is a kind of computerized speech learning machine.
At present, people's only instrument that learns a language is a tape recorder and reproducer, though it has little, the easy to carry advantage of volume, because its structure institute, part still comes with some shortcomings; First: read trouble again, it must could be realized by the manually-operated rewinding; Second: can't directly compare with the tape Received Pronunciation with reading pronunciation, it is bad to be not easy to correct one's pronunciation; Above-mentionedly allly many inconveniences have been brought to the user.
The purpose of this utility model is to overcome the deficiency of prior art and provides a kind of simple in structure, and easy to operate, dependable performance possesses repetition simultaneously, with the computerized speech learning machine of reading, record, relatively wait function outward.
The utility model is to adopt following proposal to realize: by the motor driving controling circuit of a pair of steady state controling circuit control tape recorder and reproducer and the duty of language playback circuitry, record microphone pickup signal and tape playback signal or export recording signal to loudspeaker automatically so that the language playback circuitry is realized Automatic Cycle, thereby, necessary repetition when providing people to learn a language, with reading, relatively, outer recording function.
The utility model is simple in structure, and dependable performance is easy to operate, possesses repetition simultaneously, and arbitrarily relatively follow and read, the Automatic Cycle sound-recording function, acoustical sound is the good aid that a kind of people of being suitable for learn a language.
Concrete structure of the present utility model describes in detail below in conjunction with accompanying drawing:
Accompanying drawing 2 is the utility model electrical schematic diagram.
See accompanying drawing 1,2, the utility model is by bistable state control circuit 1, language playback circuitry 2, tape circuit for controlling motor 3, microphone 4, audio frequency pre-amplification circuit 5, audio power amplifying circuit 6 is formed, described audio frequency pre-amplification circuit 5, the structure of audio power amplifying circuit 6 are all consistent with the circuit structure in the existing magnetic tape sound reproducer, and the output one tunnel of bistable state control circuit 1 connects tape circuit for controlling motor 3, another road connects the control end of language playback circuitry 2, the output of language playback circuitry 2 connects audio frequency pre-amplification circuit 5, and the output one tunnel of microphone 4 connects language playback circuitry 2, and another road connects audio frequency pre-amplification circuit 5, the output one tunnel of audio frequency pre-amplification circuit 5 connects audio power amplifying circuit 6, another road connects language playback circuitry 2, and described bistable state control circuit 1 is by resistance R 1-R8, capacitor C 1, C2, triode T1-T3, switch AN forms, and language playback circuitry 2 is by resistance R 9-R11, R17, R18, capacitor C 5-C11, integrated package 1C1 forms, tape circuit for controlling motor 3 is by resistance R 12-R16, capacitor C 3, C4, diode D1, D2, triode T4, T5, luminotron LED1 forms.
In the utility model, the model of ic chip 1 is: ISD1420.
Principle of work of the present utility model is sketched in following: because of the utility model is and the supporting use of magnetic tape sound reproducer, therefore, press the magnetic tape station playback button, circuit power is connected, bistable state control circuit 1 is in first stable state, at this moment, output one tunnel control tape circuit for controlling motor 3 of this circuit, magnetic tape station is quit work, then control language playback circuitry 2 work of another road, make the sound signal of the former storage of its repeat playing, this signal is through audio frequency pre-amplification circuit 5, audio power amplifying circuit 6 amplifies the rear drive loudspeaker, be about to the audio-frequency information repeat playing of former storage, when Push switch AN, bistable state control circuit 1 changes second stable state into by first stable state, output one tunnel control tape circuit for controlling motor 3 work of this stable state, make magnetic tape station be in tone playing state, another road output simultaneously, make language playback circuitry 2 be in recording state, the sound signal of raw tape cassette player output is after the preposition amplification of audio frequency, 2 recording of sampling input language playback circuitry, simultaneously, the operator is picked up by microphone 4 with the speech signal of reading and directly input language playback circuitry 2 recording, like this, the signal of tape signal and microphone just is recycled in the typing audio record circuit 2, at this moment, presses switch AN again, it is first stable state that second stable state is overturn again, can realize voice with reading with re-reading.
In sum, the utility model is simple in structure, dependable performance, and function is many, can arbitrarily realize repeating with reading, and relatively waits function, is a kind of aid that is suitable for language learning.
