Accompanying drawing explanation

Fig. 1 is the structural representation writing the correct body position special pens of English word described in the utility model;

Fig. 2 is the circuit theory diagrams of controller.

Detailed description of the invention

Detailed description of the invention one: present embodiment is described below in conjunction with Fig. 1 and Fig. 2, writes the correct body position special pens of English word, comprises a body described in present embodiment, the outer setting of a body has calibration function starting switch 1; The inside of body is provided with and corrects attitude control 2 and battery 3; Battery 3 provides working power for correcting attitude control 2;

Correct attitude control 2 and comprise mercoid switch K, NE555 time-base integrated circuit IC1, VT66AS22 speech IC IC2, resistance R1, resistance R2, resistance R3, resistance R4, resistance R5, resistance R6, resistance R7, electrochemical capacitor C1, electric capacity C2, electric capacity C3, NPN triode VT1, PNP triode VT2, NPN triode VT3, NPN triode VT4 and loudspeaker BL;

The positive pole of battery 3 connects one end of calibration function starting switch 1, and the other end of calibration function starting switch 1 connects the positive pole of electrochemical capacitor C1, one end of mercoid switch K normally opened contact, one end of resistance R3 and the emitter stage of PNP triode VT2 simultaneously;

The negative pole of battery 3 connects the emitter stage of the negative pole of electrochemical capacitor C1, one end of resistance R2, the emitter stage of NPN triode VT1, one end of electric capacity C2,1 pin of NE555 time-base integrated circuit IC1, one end of electric capacity C3,3 pin of VT66AS22 speech IC IC2 and NPN triode VT4 simultaneously, and ground connection;

Calibration function starting switch 1 is arranged on cap for brush outer wall.

Operation principle: the pen described in present embodiment can be used as conventional pen and uses, and now calibration function starting switch 1 is off state; Allow it as the special pens correcting posture during write words if want, first closed by calibration function starting switch 1, then battery 3 provides working power for NE555 and VTG66AS22 two chips, starts this circuit working.

NE555 time-base integrated circuit IC1, resistance R6, resistance R7 and electric capacity C2 form astable multivibrator, and the power supply of this astable multivibrator is controlled by PNP triode VT2.And whether PNP triode VT2 conducting depends on the position of mercoid switch K, when writing posture is incorrect, the angle that pen tilts not pair time, mercury in mercoid switch K is by the short circuit of two electrode overlap joints, then the base stage of NPN triode VT1 is added with bias voltage, conducting, thus PNP triode VT2 saturation conduction, astable multivibrator works, the 3 pin high level of NE555 time-base integrated circuit IC1, after the 1 pin access high level of IC2, IC2 is triggered work, 2 pin of IC2 pass through VT3, VT4 amplifies rear drive loudspeaker BL and provides voice reminder, so that it should be noted that self writing posture has problem, timely adjustment, correcting writing gesture, the bathomorphic incidence of disease of effective reduction, and improve learning efficiency.
