A speaker is used to convert electrical energy into sound waves, allowing audio signals to be heard by an audience. It typically consists of a diaphragm that vibrates when an electrical current passes through the speaker's coil, creating sound. Speakers are found in various devices, including home audio systems, computers, and portable speakers, enabling users to enjoy music, podcasts, and other audio content. They can be designed for different purposes, such as clarity for dialogue or enhanced bass for music.
