It consists of main components: a woofer (for bass sounds) and a tweeter (for high-frequency sounds), along with a crossover to separate frequencies. Its working principle is based on the laws of electromagnetism that move a diaphragm to produce sound waves. Speakers are used in various applications such as home audio systems, cars, concerts, and portable devices, with sound quality influenced by design and technology. There are active speakers (with internal amplifiers) and passive ones (requiring an external amplifier).
