The specific embodiment
A kind of as shown in Figure 1 acoustic control music " Santa Claus ", comprise flannelette " Santa Claus ", also comprise the acoustic control acoustics circuit that is arranged in flannelette " Santa Claus " body, the acoustic control acoustics circuit comprises the positive pulse circuits for triggering, the sound equipment phonation circuit, amplify and flasher circuit, the positive pulse circuits for triggering comprise piezoelectric ceramic piece B, transistor VT1, biasing resistance R1, wherein piezoelectric ceramic piece B one end is connected with transistor VT1 emitter stage, the piezoelectric ceramic piece B other end is connected with transistor VT1 base stage and biasing resistance R1 one end respectively, and the biasing resistance other end is connected with transistor VT1 colelctor electrode, connect positive source; The sound equipment phonation circuit comprises music integrated circuit IC, oscillation resistance R2, capacitor C, wherein the TG of music integrated circuit IC end is connected with transistor VT1 emitter stage, music integrated circuit ICVDD hot end is connected, connects positive source with oscillation resistance R2 one end, concussion resistance R 2 other ends are connected with music integrated circuit ICOSC concussion end and electric capacity one end respectively, and the electric capacity other end is connected, connects power cathode with music integrated circuit ICVSS cold end respectively; Amplification and flasher circuit comprise transistor VT2, loudspeaker BL, light emitting diode VD1, VD2, wherein loudspeaker BL, light emitting diode VD1, a VD2 end in parallel are connected with positive source, the other end is connected with transistor VT2 colelctor electrode, transistor VT2 base stage is connected with music sounding circuit ICOUT output, and transistor VT2 emitter stage connects power cathode.
As shown in Figure 2, light emitting diode VD1, VD2 are separately positioned in flannelette " Santa Claus " eye socket.Loudspeaker BL is arranged in flannelette " Santa Claus " oral cavity.Piezoelectric ceramic piece B is arranged in flannelette " Santa Claus " abdominal cavity.Power supply is 3 volts of direct currents.
Below in conjunction with operation principle and illustrate implementation method:
As shown in Figure 2, at ordinary times because the biasing resistance R1 value of transistor VT1 is bigger, so VT1 is in incomplete conducting state, the low level of gas emitter stage output＜1/2VDD=1.5V, the trigger end TG of the music integrated circuit IC that is attached thereto also is in low level, the IC internal circuit is not worked, transistor VT2 by, loudspeaker BL is noiseless.When clapping palm in EFFECTIVE RANGE (less than 1m) scope, piezoelectric ceramic piece B receives the sound wave of bursting, and converts the corresponding signal of telecommunication to.The positive half cycle of this signal of telecommunication is after transistor VT1 amplifies, make its emitter stage output positive pulse signal of telecommunication, directly trigger the world masterpiece in music theme signal of telecommunication of music integrated circuit IC from OUT end output one bent interior storage, after transistor VT2 power amplification, promotion loudspeaker BL sends loud He Qu in red-letter day and comes.Meanwhile, light emitting diode VD1, the VD2 that is connected in parallel on loudspeaker BL two ends also can send synchronous passage of scintillation light with sound.Circuit acoustic control part has unique distinction when design: one, with the intrinsic input resistance that exists between the TG of music integrated circuit IC and VSS end, direct emitter stage load resistance as transistor VT1 has saved a RSET.Its two, piezoelectric ceramic piece B is directly across between the base stage and emitter stage of VT1, and anomaly is connected between the base stage and power cathode of VT1, purpose is to significantly improve sound controling sensitivity.In addition, R1 is as the biasing resistor of VT1, and the resistance size directly influences sound controling sensitivity.Have only when the R1 value is suitable, the emitter stage of VT1 can be exported the voltage a little less than＜1/2VDD=1.5V when static state, and circuit just can have than higher acoustic control trigger sensitivity.If the R1 value is excessive, then the bias current that provides to VT1 is almost nil, VT1 be tending towards when static by, will not have the effect of effective raising sound controling sensitivity.Otherwise, if the R1 value is too little, being tending towards saturated when then VT1 is static, IC can be in high level＞1/2VDD continuous firing all the time because of the TG end, circuit generation, luminous more than.
In the circuit, the 12 first world masterpiece in music themes that music integrated circuit IC stored whenever are subjected to once triggering, and the only output bent world masterpiece in music theme signal of telecommunication wherein, and 12 first masterpieces in music is according to the definite sequence output that circulates successively.R2 and C are respectively the external oscillation resistance device and the capacitor of music integrated circuit, the performance speed of numerical values recited decision melody.
