Here the circuit diagram of eight sound effects generator. The circuit will generate 8 type of sound effect, amplify the audio signal, so you will hear the sound directly from the speaker.
IC KS5401 will generate the sound, while TR D438 used to be amplified the audio signal. I’ve try to find the datasheet for KS5401, but unfortunately I did not find it.
Please make sure you find the KS5401 first before you build this circuit.
