Mini hi-fi speaker. Cheap brand.
Electronic speakers are devices that convert electrical signals into audible sounds. Speakers work by running electrical signals into a voice coil, causing it to move back and forth. A cone-shaped diaphragm attached to coil moves along with it, pushing against the air to produce sound waves. Speakers are used in a wide variety of situations, from massive loudspeakers designed for public announcements in a large, noisy environment to residential hi-fi speakers used for listening to music.
Working speakers can be found plugged into computers, stereos, and TVs, while broken ones are bundled in the mess of an e-waste dump.
