When you turn down or up the volume on devices with either a wheel or button, what actually happens that allows it to sound quieter or louder?
In: Technology
Two different methods.
Analog devices are often continuous and involve the moving of a variable capacitor or resistor to change the electric makeup going to the speaker.
In a digital device nothing changes really, the knob is a user interface that tells a circuit to apply more or less voltage. However b/c it’s digital (all 1s and 0s) you never get continuous band control. Think if you’ve ever had a problem with a digital speaker that is too loud on one step and too quiet on the lower step
