Embodiment
In Fig. 1, with wiring board 3 is the center, wiring board 3 is fixed on the bottom 7, loudspeaker 2 is fixed on the bottom 7, matrix detects grid 10 and sticks on the bottom 7, switching circuit plate 9 is fixed on the bottom 7, loudspeaker 2, matrix detects grid 10, switching circuit plate 9, high-frequency signal pick-up unit 8, earphone jack 4, the flash voice storage card 5 of storage system all is connected with wiring board 3 by lead, integrated above-mentioned microprocessor system in the wiring board 3, audio frequency processing system, high-frequency signal generation circuit, modulation-demodulation circuit 14 is amplified in high-frequency signal filtering, liquid crystal drive display circuit 13, recording playing circuit 16, PC interface circuit 15.The circuit theory diagrams of wiring board 3 are with reference to Fig. 2.The MPU11 of microprocessor system links to each other with the functional chip of outside by the I/O bus and carries out communication in Fig. 2, concrete workflow is as follows: the MPU11 of microprocessor system regularly detects grid 10 to matrix through the I/O bus by interrupt handling routine and sends the high frequency waves signal, meanwhile high-frequency signal receiver 8 is passed to filtering amplification modulation-demodulation circuit 14 with the signal of accepting, the result that will handle gives microprocessor MPU 11 again, MPU11 judges that according to this result high-frequency signal receiver 8 is whether on current that insulated conductors that high-frequency signal arranged, the position of detection signal receiving trap on another direction if then use the same method, can determine the planimetric coordinates of receiving trap 8 present positions thus, MPU11 is according to this coordinate then, delivers to audio frequency processing system 17 with the corresponding compressed voice data of this page zone record content of the corresponding books of this coordinate and decodes being stored in storage system 12 in advance, pass to loudspeaker 2 after the amplification; Simultaneously, microprocessor will need the brilliant display circuit 13 that drives of data presented content liquor charging, show on liquid crystal 6.If receiving trap 8 on current that insulated conductors that high-frequency signal arranged, does not then continue scan round.The receiving antenna end of receiving trap 8 can be the form of a stroke or a combination of strokes, its antenna flank top coated metal guard.
Matrix detects grid can take following structure, as shown in Figure 3, there is the insulated conductor of insulation course plane separation to be become some lattice pieces from the vertical and horizontal both direction, each insulated conductors one terminates on the I/O bus, the other end is unsettled, the vertical and horizontal insulated conductor can interlock or intersection or lamination but disconnect, and microprocessor adds successively and send the high-frequency signal (claiming scanning again) can be according to from top to bottom, order from left to right.Certainly also can take other suitable scan modes.
The detection principle that the utility model matrix detects grid can be following mode, with reference to Fig. 4, the part of choosing matrix detection grid describes, generally, add on insulated conductor a by the I/O bus and to send an above square wave of 8K, around this insulated conductor, can give off the electric field of a variation, can influence receiving trap 8 and receive the high-frequency signal quality, and then influence be to the highly sensitive detection of its position in the short time.In order to solve this deficiency, insulated conductor a add send a 8K square wave in, for its adjacent insulated conductor b, c adds 0 level, the high-frequency electric field that is sent by insulated conductor a is because of the obstruct of insulated conductor b, c zero line like this, and be limited between insulated conductor b, the c, a little less than zone outside insulated conductor b, the c can become very.The high-frequency electric field of insulated conductor a is very little to the regional effect outside insulated conductor b, the c like this.Like this reason adds when sending high-frequency signal at other insulated conductors, and the adjacent insulated conductor of this insulated conductor adds 0 level equally.Carry out by that analogy.
Use of the present utility model can be taked following manner, show as Fig. 5, the page pattern of books and matrix detect grid corresponding relation figure, and (grid among the figure does not exist in the page of reality, on behalf of matrix, it detect grid, for convenience of description it is appeared in one's mind on page), the testing process of the sign on the following brief description page (page) (record content): suppose the place of current demand signal receiving trap in 1 ' number line and 2 ' number line intersection, when the MPU scan matrix detects network lateral isolation lead (line), only 1 ' during number line place emission high-frequency signal, signal receiving device ability received signal, at this moment MPU writes down the value of this direction, then scan vertical insulated conductor (alignment), to 2 ' during number line, signal receiving device just can receive signal, MPU writes down the value of this direction again, MPU just can determine the planimetric coordinates of the indicated position of signal receiving device like this, make corresponding subsequent processing again according to said circumstances, for example: read, put question to, test, put the music on, contents such as liquid crystal display.
