4. How do computer speakers make sound?Inside each speaker is a voice coil that moves a cone back and forth when electricity flows through it. The moving cone pushes air, creating sound waves that we can hear.

Transducer: A device that converts one form of energy into another, such as electrical to acoustic energy.
Voice Coil: A coil of wire attached to a speaker cone that moves within a magnetic field to produce sound.
Acoustic Energy: Energy in the form of sound waves that travel through a medium like air.
Digital Signal Processing (DSP): The manipulation of digital audio signals to improve sound quality, add effects, or optimize output.
