A Speaker Driver is the individual circular driver unit that produces the sound we hear when we play all types of audio. Individual speakers are often called ‘drivers’ where the entire unit together will sometimes by called the ‘loudspeaker’How do they work?Speaker Drivers work by transforming an electrical audio signal they receive into sound waves which we eventually hear as the output. As it moves, it creates a pressure wave from both the front and from the back. As it moves towards you, it creates a positive pressure and pulls the air behind it.Where might I use one?Wireless speaker systemPortable speakersTV speakersHome theatresHi-Fi systemsSound barsPA systemsHeadphonesTelephonesFrequency TypesFull Range drivers – Designed to be used alone, which helps them produce higher quality audio in most cases.
