Multi Sound Effect Circuit using HT2884

Here is multi sound effect can also effect generator. this circuit work with icĀ  HT2884. Power is a 3 Volt battery, but the IC will work with any voltage between 2.5 – 5 Volts. Switch S1 is the on / off switch. The output at pin 10 is amplified and drives a small 8 ohm loudspeaker. Pressing S3 once will generate all the sounds, one after another. S2 can be used to produce a single sound effect, next depression gives the next sound effect. Standby current is about 1 uA at 3 Volt, so battery life is very economical. here are 8 different sound effect can be produced that are 2 lazer guns, 1 dual tone horn sound, 2 bomb sounds, 2 machine gun sounds and a rifle shot sound.
