Speaker

A speaker is an electroacoustic transducer that converts electrical audio signals into sound waves by moving air through mechanical vibration. It typically consists of a permanent magnet, voice coil, diaphragm (cone or dome), and frame that work together to produce audible sound. When electrical current flows through the voice coil, it creates a magnetic field that interacts with the permanent magnet, causing the attached diaphragm to move back and forth and generate sound waves. Speakers are commonly used in audio systems, electronics projects, and communication devices to produce music, speech, alerts, and other audio output.
