DIGITAL MUSIC SOUND AMPLIFIER is one of a circuit that will produce sounds that can attract people’s attention. The beautiful sounds will occur if we manage to pick the 10 resistors properly and carefully. We can use whatever value of the resistors that we want. But if we want the good result to be obtained, we a use the value of resistor from 470 ohm until 10k ohm of resistors.
To obtain a nice result, we have to preset 1M ohm of variable resistor for the tempo and for the tones, we also have to preset the variable resistor by using 50k ohm resistor. In this circuit we have to use voltage supply in a range of 5 volt to 6 volt only.
This circuit can be provided the many types of the interested sounds, if used the right resistor. Generally, this circuit is used in the music box, key board, handset, computer and any thing product can be producing the any sound.
In computer or handset, we can select any sound. But, before that we must set the value at variable resistor.
