How headphones work




Headphones are a pair of conversion units that receive electrical signals from a media player or receiver and use speakers close to the ear to convert them into audible sound waves. Headphones are usually detachable from the media player and connected with a plug. The advantage is that you can listen to the sound on your own without affecting others. You can also separate the sound of the surrounding environment, which is very helpful for people who use it in noisy environments such as recording rooms, bars, travel, sports, etc. Earphones were originally used for telephones and radios, but with the popularity of portable electronic devices, earphones are mostly used for mobile phones, Walkman, radios, portable video games and digital audio players.
