A microphone is a device that captures sound and converts it into an electrical signal. It is commonly used in various settings, such as recording music, amplifying voices during speeches, or even in smartphones for phone calls. Microphones come in different types, including dynamic and condenser microphones, each suited for specific purposes. When you speak into a microphone, it picks up the sound waves created by your voice. These sound waves cause a diaphragm inside the microphone to vibrate, which then generates an electrical signal. This signal can be amplified, recorded, or transmitted, allowing your voice to be heard clearly in different environments.
