Clever use of sound and light integrated circuit 10 cases


In the colorful world of toys, there have been many vivid and vivid voice electronic toys such as voice-activated electronic birds, light-control electronic frogs, space fantasy echo spacecraft, electronic police cars and electronic ambulances , "Big Brother" phone, electronic toys, toys, sound and light guns and so on. Acoustic electronic toys available, won the majority of parents and children's favorite. Analog audio integrated circuit is the core of electronic toys with sound, it can issue a variety of analog sound, such as percussion, piano, accordion, mandolin and other musical instruments, crickets, frogs, birds singing, running water, windy, under Rain sound, vehicles, aircraft, sirens, guns and all kinds of explosions, such as the sound of the natural sound. Analog audio integrated circuits with high cost performance, which has been widely used in a wide range of electronic toys, instrumentation, security alerts and many other fields. This article describes the application of analog sound integrated circuit.


Happy Nature Figure 1 is a typical application of eight analog sound integrated circuit schematic. IC has 8 trigger TG1 ~ TG8, respectively, followed by eight key switches SB1 ~ SB8, you can send crickets, 蝈 蝈, cuckoo, frogs, cattle, hooves, etc. 8 different sounds. IC can be used to produce audio key ring, animal toy piano and other small electronic products. Here is a use of two (or more) analog sound integrated circuit assembly fun sound effect generator, the specific circuit shown in Figure 2. It consists of square wave generator, scan voltage generator, sound generator and power amplifier circuit and other components. On the one hand, the scan voltage generator regularly changes the power supply voltages of the analog integrated circuits IC1 and IC2 under the action of a square wave generator to control the output of the analog acoustic signals. On the other hand, the output terminal of the IC1 controls the IC2 Oscillator input (or IC1 and IC2 mutual control). The circuit shown in Figure 2 can produce nearly a hundred kinds of sound effects, such as low cricket cricket, frog drum noise, cicadas singing and so on.
