Abstract
The utility model provides an auxiliary device for repeat reading and following reading of sound recording/playing machine which can be matched with an ordinary sound recording/playing machine for use and is mainly composed of a speech recording module, a power amplifier, an earphone jack, a microphone, an input plug inserted into the earphone jack of the sound recording/playing machine, and an output control plug inserted into an external power-supply jack of the sound recording/playing machine. The audio signals inputted from the earphone jack of the sound recording/playing machine are recorded and outputted by the speech recording module, and an external power supply for the sound recording/playing machine is controlled by the output control plug, so that the functions of repeat reading and following reading are achieved. The device is widely used for language learning and entertainment.
Description
The utility model relates to a kind of recording playback machine attachment device, is mainly used in recording playback machine and sets up re-reading with reading function.
At present, the language learning device is generally recording playback machine and re-reading reading following machine structure is integrated, and the input signal of its language writing circuit is taken from the circuit output of this recording playback machine, the power supply of this output signal control core motor, realize suspending playback, start re-reading with reader.Exist the cost height, price is expensive and can't be the shortcoming of other recording playback machine service.
It is a kind of re-reading with reading attachment device that the purpose of this utility model is to provide, with the supporting use of recording playback machine, to remedy the weak point of existing recording playback machine and language learning device.
The utility model mainly is made up of input plug, control output plug, earphone jack, language recording module, amplifirer and microphone; Input plug is connected to the audio signal input end of language recording module through coupling capacitance, and the audio signal output end of this language recording module links to each other with volume potentiometer through a capacitor, and the tap of this volume potentiometer connects lug machine transplanting of rice hole behind the amplifirer; The control output end of above-mentioned language recording module is connected with the base stage of the final stage triode of compound transistor behind a resistance, the feeder ear of the emitter of this compound transistor and above-mentioned language recording module connects positive source altogether, and its collector links to each other with the control output plug; Microphone one is terminated at the signal input part of above-mentioned language recording module, other end ground connection; During use, this device input plug inserts the earphone output plughole of recording playback machine, and its control output plug is connected to the external power supply jack of recording playback machine.Its principle of work is: the sound signal of coming from the input plug that is connected to recording playback machine earphone output plughole is through the audio signal input end of capacitor-coupled to the language recording module, behind language recording module record, audio signal output end output from this module, arrive volume potentiometer through a capacitor-coupled, enter amplifirer from the volume potentiometer tap, signal enters earphone jack from its output terminal after amplifying.When re-reading, the control signal of language recording module is controlled compound transistor from its output terminal and is ended behind current-limiting resistance, makes the output plug outage that links to each other with its collector, cuts off the power supply of recording playback machine, and its inner tape stops playback.Meanwhile, the audio signal output end of language recording module is exported the sound signal of its former record, still through the laggard pleasant machine transplanting of rice of above-mentioned capacitor, potentiometer and power amplifier hole, finishes re-reading program.When cancellation was re-reading, the control signal output ends output control signal of language recording module made the compound transistor switch conduction, the output plug energising, thus recording playback machine is reworked.When reading, the signal input part that the signal to be recorded that is received by microphone is input to the language recording module enters the language recording module and is recorded, when needing again through former that reader be carried out to such an extent that read.During supporting uses of this Mk and the recording playback machine that adopts AC power, only need set up the interlock circuit of controlling AC power and get final product.
The utlity model has simple in structurely, easy to use, it is re-reading with reading advantage such as function that common recording playback machine is set up, and is widely used in language learning and Karaoke amusement etc.
Description of drawings: Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model electrical schematic diagram.
Below in conjunction with accompanying drawing the utility model is further described.The audio signal input end a of language recording module A (can select VP-107 for use) is connected to capacitor C1, and the other end of this capacitor C1 is connected to input plug X1; The audio signal output end d of this language recording module A meets volume potentiometer RV through capacitor C2, and the tap of volume potentiometer RV meets power amplifier B (can adopt TDA-2822), and the output terminal g of this amplifier B is connected to earphone jack J; The control signal output ends c of this language recording module A connects the base stage that is connected to the triode Q2 in the compound transistor of being made up of triode Q1, Q2 after the resistance R, the collector of this compound transistor is connected to control output plug X2, the feeder ear e of its emitter and language recording module A is connected to the positive pole of power supply jointly, record button S1 is connected to the recording control end n of language recording module A, and re-reading button S2 is connected to the re-reading control end m of this language recording module A.
Claims (1)
1, a kind of recording playback machine is re-reading with reading Mk, mainly form by input plug, control output plug, language recording module, amplifirer, earphone jack and microphone, it is characterized in that input plug is connected to the audio signal input end of language recording module through coupling capacitance, the audio signal output end of this language recording module links to each other with volume potentiometer through a capacitor, and the tap of this volume potentiometer connects lug machine transplanting of rice hole behind the amplifirer; The control output end of above-mentioned language recording module is connected with the base stage of the final stage triode of compound transistor behind a resistance, the feeder ear of the emitter of this compound transistor and above-mentioned language recording module connects positive source altogether, and its collector links to each other with the control output plug; Microphone one is terminated at the signal input part of above-mentioned language recording module, other end ground connection; During use, this device input plug inserts the earphone output plughole of recording playback machine, and its control output plug is connected to the external power supply jack of recording playback machine.
