The specific embodiment

In conjunction with the accompanying drawings, will describe the specific embodiment of the present utility model in detail.

Fig. 1 is the structural representation of the utility model embodiment.Gift box is play in many lids magnetic induction of present embodiment automatically, be provided with inner box 1, inner box 1 hinged internal head cover 7 suitable for reading, dividing plate 3 vertically is set before the rear quarter panel 4 in inner box 1, thereby between rear quarter panel 4 and dividing plate 3, form cavity, be horizontally disposed with circuit card 2 in this cavity upper end, battery 5 and the loud speaker 6 that is electrically connected with circuit card 2 is set in described cavity.Inside face or outside face fixed magnet 8 at described internal head cover 7, in this example, top cover 10 outside the identical or close articulated position in internal head cover 7 outsides is hinged with, also at hinged first side cover 11 in two sides of inner box 1 and second side cover 12, also fixed magnet 8 on top cover 10 (with internal head cover 7 diverse location places), first side cover 11, second side cover 12 outside, the position of corresponding magnet 8 is respectively equipped with magneto sensor 9 on circuit card 2, as dry-reed tube, magnetodiode, mistor, magnetic sensitive transistor and/or Hall element etc.

Principle of work block diagram of the present utility model as shown in Figure 2, phonation circuit on the circuit card 2 is provided with central processor CPU, the memory device (as RAM, ROM, FLASH, EPROM etc.) that stores the alternative sounds content in advance is connected the input end of CPU, the mouth of CPU is connected with chipspeech, and chipspeech output voice signal is to acoustical generator such as loud speaker or earphone sounding.CPU reception magnetic switch is the energizing signal that the testing circuit of magneto sensor composition transmits, CPU according to current energizing signal by analysis with handle after, send corresponding order and give chipspeech, after chipspeech receives instruction, access corresponding voice digital signal internally, after the process decoding is reduced into simulate signal, output to loudspeaker or earphone by this chip power amplifier end, sending institute can audible sound.

Fig. 3 is the utility model schematic circuit diagram.The phonation circuit chip is the AM4EG series of Youhua Micro-Electronic Co., Ltd.'s exploitation.This chip has 34 pins, and wherein the part pin is not temporarily used.Die size is: 2330um * 4649um, spot size is: 80um*80um, chip chassis ground.Pin 3 is a PWM internal digital power amplifier output port, pin 7 external oscillation resistance Rosc are to regulate broadcasting speed, the Rosc value is more little, broadcasting speed is fast more, pin 11 is a reseting port, and pin 12 is that port is selected in PWM/COUT digital power amplifier/analogue audio frequency output, and pin 5 is the difunctional pin of analog/digital power amplifier: when pin 12 ground connection, select digital power amplifier,

3,5 directly connects the loudspeaker playback; When pin 12 power connections were anodal, digital power amplifier was closed, and the sound signal of pin 5 outputs promotes the loudspeaker playback after aerotron amplifies.

In this example, have 4 lids, then the micro controller system of this chip internal is provided with 4 magnetic switch of 4 ports connections, and port can be expanded, and each port is in 1,0 conversion of high-low level.Used 4 ports wherein in the present embodiment:

8,13,14,15, other untapped pins are standby.

Because the distance of the magneto sensor of magnet on circuit card on each lid is different, therefore, if the too high meeting of intensity of the magnet that distance is near makes adjacent magneto sensor misoperation, make the content confusion reigned of being read, so on different lids, lay the magnet that different size also is a varying strength, also reduced cost simultaneously.Because magnet divides N, S the two poles of the earth, so the magnetic pole of the magnet that this gift box covers makes the magneto sensor cisco unity malfunction with respect to the position maintenance direction unanimity of circuit card otherwise can cause magnetic pole short circuit, magnetic-field intensity to reduce because of magnetic pole in the same direction is different.Different magneto sensors 9 by respective magnets 8 near or away from opening or close action, thereby control corresponding broadcast work for energizing signal of phonation circuit.

Its principle of work is as follows: after powering on, thereby the reset circuit that aerotron 8550 and capacitor C are formed make pin 11 in short-term high level inner micro controller system is resetted, the continuous scan in port of micro controller system then, when lid is opened, the magneto sensor resistance variations (diminishes for resistance in this circuit or is 0, cause corresponding ports to become low level 0, and the corresponding magneto sensor of the lid of not opening is 1 because of resistance makes the port level greatly, micro controller system just according to this a series of 0,1 combination, it is the N bit, micro controller system calls corresponding instruction to chipspeech according to the sequencing of this row combination, through moving loudspeaker of synthetic pusher or earphone pronunciation, playing the back does not have change as port, then changes sleep state over to reduce power consumption.

The structure of above gift box is when being provided with, the position that magnet on each lid is provided with is corresponding with the magneto sensor 9 on the circuit card 2 as far as possible, as shown in Figure 1, magnet 8 on the lid is oblong, be horizontally disposed with, the magneto sensor horizontally set relative with top cover magnet, the magneto sensor relative with side cover magnet then vertically are provided with, and so make the magnetic induction signal the most responsive.

Suitable variation also can take place in the structure of above gift box, can utilize the position of placing circuit card that inner box is separated into different cavitys in other positions of the upper surface of inner box such as: the position of circuit card, and this scheme is applicable to bigger gift box.Can adjacent side cover and/or top cover be set according to the diverse location of circuit card placement, corresponding magnet in position and magneto sensor be set simultaneously, to reach above-mentioned same purpose.

Certainly, the foregoing circuit plate also can be arranged on the side or with the parallel sided setting, as long as the outer lid of inner box has the part position mutually close with this circuit card, and can in the position that is close corresponding magnet and magneto sensor be set respectively after covering.

Each lid also can be by not being articulated and connected, as connecting by the mode that fastens.

Above-mentioned magnet is preferably magnet steel.
