Speakers are devices that convert electrical signals into sound, allowing us to hear music, voices, and other audio. They come in various shapes and sizes, from small portable Bluetooth speakers to large home theater systems. The quality of sound can vary, with some speakers designed for deep bass and others for clear vocals. In addition to physical speakers, the term can also refer to people who deliver speeches or presentations. These public speakers engage audiences by sharing ideas, stories, or information. Whether in a classroom, conference, or online, effective speakers use their voice and body language to connect with listeners.
