Abstract
The utility model discloses an MP3 for foreign language listening and repeat training. The MP3 comprises an earphone jack, a microphone, a memory unit, and a power supply unit all connected with a singlechip circuit, and is characterized in that the microphone is connected with an analog-to-digital converter and a trigger circuit; the other end of the trigger circuit is connected with a supply switch; the supply switch is connected with a supply unit; and a compulsive locking switch is arranged between the supply switch and the supply unit. Compared with the prior art, the MP3 can automatically judge repeat state, and triggers to close the supply switch when repeat is completed, so as to stop display and save power supply. In addition, the breakpoint is clear, so that continuous learning is facilitated.
Description
[technical field]
The utility model relates to a kind of language teaching apparatus, and particularly a kind of being applicable to carried out hearing with the device of reading to train.
[background technology]
Current, be used for the MP3 player that digital music is appreciated since volume little, in light weight, be not afraid of vibration, typing repeatedly, audio-source and come advantages such as automatic network, extensively be applied to the Listening Training of English.But in actual applications, the time was carried out hearing with reading to train before many people utilized and sleep, after entering sleep unconsciously, machine can not stop automatically, if selected the repeat playing function, just can stop after having only battery to deplete, wasted electric energy on the one hand, second day use may be delayed, on the other hand, the breakpoint location of last training can not be clearly known next time when using.
[utility model content]
Technical assignment of the present utility model is at above the deficiencies in the prior art, provides a kind of and can judge automatically that the foreign language listening of following read states is with reading training MP3.
The technical scheme in the invention for solving the technical problem is: a kind of foreign language listening is with reading training MP3, comprise the receiver J-Horner, microphone, storage unit, the power supply unit that are connected with single chip circuit, it is characterized in that: microphone connection mode number converter, trigger circuit, the trigger circuit other end links to each other with power switch, power switch links to each other with power supply unit.
Also has the positive lock switch between power switch and power supply unit.
Between above-mentioned analog to digital converter, the trigger circuit resonance filter is arranged.
Between above-mentioned resonance filter, the trigger circuit amplifying circuit is arranged.
Compared with prior art, the utlity model has following outstanding beneficial effect:
1, judges automatically with read states,, stop to play, save power supply when stopping to close power switch with triggering after reading;
2, breakpoint is clear and definite, the study of being convenient to continue.
[description of drawings]
Fig. 1 is a structure function block diagram of the present utility model.
[embodiment]
Below in conjunction with specification drawings and specific embodiments the utility model is further specified.
As shown in Figure 1, the utility model comprises receiver J-Horner, microphone, storage unit, the power supply unit that is connected with single chip circuit, microphone, analog to digital converter, resonance filter, amplifying circuit, trigger circuit are linked in sequence, and the trigger circuit other end links to each other in proper order with power switch, positive lock switch, power supply unit.
When being in read states, the microphone collection is with reading sound, through analog to digital converter, sound signal transfers electric signal to, electric signal enters resonance filter and carries out filtering removal background noise, and through the amplifying circuit power amplification, the electric signal of amplification enters trigger circuit, trigger circuit continue to send the triggering electric signal and are communicated with power switch, and power supply is provided.When the microphone collection less than when pronunciation, no electric signal enters trigger circuit, power switch is closed, power supply stops.
Whether the positive lock switch is used for the positive lock pattern, also promptly no matter have with reading the use of the utility model continued power.The positive lock switch can be single-pole double-throw switch (SPDT), and power switch and power supply unit disconnect during locking, and power supply unit directly is connected with single chip circuit.During unlock state, power switch is connected with power supply unit.
Need to prove; particular of the present utility model is described in detail the utility model; for a person skilled in the art, in the various conspicuous change of under the situation that does not deviate from spirit and scope of the present utility model it being carried out all within protection domain of the present utility model.
Claims (4)
1. a foreign language listening is with reading training MP3, comprise the receiver J-Horner, microphone, storage unit, the power supply unit that are connected with single chip circuit, it is characterized in that: microphone connection mode number converter, trigger circuit, the trigger circuit other end links to each other with power switch, power switch links to each other with power supply unit.
