Abstract

The utility model provides a kind of tape recorder and reproducer with timer, comprise tape recorder and reproducer, the attaching plug of tape recorder and reproducer and the power lead of connection tape recorder and reproducer and attaching plug, it is characterized in that: on described power lead, be circumscribed with timer, described timer comprises switch, 555 timers and relay, described attaching plug provides direct supply, motor is provided with in tape recorder and reproducer, technique effect of the present utility model: structure is simple, a timer transformed by the power lead of existing tape recorder and reproducer, for tape recorder and reproducer increases timing function, make magnetic tape record/play function substitute alarm clock calling student get up and study English, timer timing is convenient and swift, very applicablely like that the student of English study uses.

Description

A kind of tape recorder and reproducer with timer

Technical field

The utility model relates to tape recorder and reproducer conventional in study, specifically a kind of tape recorder and reproducer with timer.

Background technology

Tape recorder and reproducer has very large booster action for the English study of student, a lot of student likes carrying out in the morning reading morning in order to the listening and speaking ability improving English, but because learning pressure is large, get up morning is all by alarm clock calling, alarm clock calling is got up poor effect and affect the learning enthusiasm of student, morning, tape recorder and reproducer started playback automatically, read aloud English, thus play and remind student to get up the destination of study, student is waken up by reading English, and enforceablely inculcated English, improve the learning efficiency of English, and existing most of tape recorder and reproducer can not play the function of fixed time airplay, automatically tape can not be play in predetermined time, so need to carry out upgrading to existing tape recorder and reproducer.

Utility model content

The utility model provides a kind of tape recorder and reproducer with timer according to the deficiencies in the prior art, automatically plays tape, easy to use, improves the learning efficiency of student.

The technical solution of the utility model: a kind of tape recorder and reproducer with timer, comprise tape recorder and reproducer, the attaching plug of tape recorder and reproducer and the power lead of connection tape recorder and reproducer and attaching plug, it is characterized in that: on described power lead, be circumscribed with timer, described timer comprises switch, 555 timers and relay, described attaching plug provides direct supply, is provided with motor in tape recorder and reproducer.

One end of described switch connects the base stage of transistor VT, the other end of switch, the collector of transistor VT connect the positive pole VCC of direct supply, the emitter of transistor VT connects pin 2 and the pin 6 of 555 timers, the pin 4 of 555 timers and pin 8 meet the positive pole VCC of direct supply, the pin 1 of 555 timers meets the earth terminal GND of direct supply, the pin 3 of 555 timers connects one end of relay coil, the earth terminal GND of direct supply, the positive pole VCC of another termination direct supply of relay coil, the normally opened contact of relay controls to be provided with motor in tape recorder and reproducer.

The direct supply that described attaching plug provides is 12V direct supply.

Technique effect of the present utility model: structure is simple, a timer transformed by the power lead of existing tape recorder and reproducer, for tape recorder and reproducer increases timing function, make magnetic tape record/play function substitute alarm clock calling student get up and study English, timer timing is convenient and swift, very applicablely likes that the student of English study uses.

Accompanying drawing explanation

Fig. 1 is the utility model one-piece construction schematic diagram;

Fig. 2 is the utility model electrical block diagram.

Embodiment

Below in conjunction with accompanying drawing, the utility model is further illustrated:

As illustrated in fig. 1 and 2, a kind of tape recorder and reproducer with timer, comprise tape recorder and reproducer 1, the attaching plug 2 of tape recorder and reproducer 1 and the power lead 3 of connection tape recorder and reproducer 1 and attaching plug 2, it is characterized in that: on described power lead 3, be circumscribed with timer 4, described timer comprises switch 401,555 timer 402 and relay 403, described attaching plug 2 provides direct supply 200, is provided with motor 100 in tape recorder and reproducer 1.

One end of switch 401 connects the base stage of transistor VT, the other end of switch 401, the collector of transistor VT connects the positive pole VCC of direct supply 200, the emitter of transistor VT connects pin 2 and the pin 6 of 555 timers 402, the pin 4 of 555 timers 402 and pin 8 meet the positive pole VCC of direct supply 200, the pin 1 of 555 timers 402 meets the earth terminal GND of direct supply 200, the pin 3 of 555 timers 402 connects one end of relay 403 coil, the earth terminal GND of direct supply 200, the positive pole VCC of another termination direct supply 200 of relay 403 coil, the normally opened contact of relay 403 controls to be provided with motor 100 in tape recorder and reproducer 1.

The direct supply 200 that attaching plug 2 provides is 12V direct supply.

When needing to use tape recorder and reproducer to carry out English study in morning, first plug is inserted in socket and switches on power, civil power is converted to the 12V direct supply of work tape recorder and reproducer and timer use by the converter in plug, close the switch of timer, regulate the adjustable resistance RP of timer, thus regulate the timing of timer, set the time needed, in time reaching the time of setting, timer is triggered, timer output end pin 3 exports high level, relay electric-loss quits work, normally opened contact J-1 discharges, the motor being connected to the tape recorder and reproducer on J-1 is started working, play Tape Contents, if desired, time tape recorder and reproducer carries out daily broadcasting tape work, the switch of timeing closing device, plug directly connects motor by power lead, carries out tape broadcasting.

A kind of tape recorder and reproducer with timer of the present utility model, structure is simple, a timer transformed by the power lead of existing tape recorder and reproducer, for tape recorder and reproducer increases timing function, make magnetic tape record/play function substitute alarm clock calling student get up and study English, timer timing is convenient and swift, very applicablely likes that the student of English study uses.
