All You Ever Wanted To Know About Earphones

Earphones are usually a set of tiny loudspeaker drivers worn around or on the head itself near a user’s ears for music listening. They are electronic transducers, that convert an electric signal into a corresponding sound. In the past, the conventional earphone designs used metal plates on the outside and were prone to feedback. This may sound bad but it is common in conventional headphones. They also have an earphone jack that connects to the headphone amplifier and the amplifier creates the sound. It is usually placed on the side of the head so as not to block any sound that may come through your neighbor’s speakers.

The earphones should not produce sound beyond the volume allowed by the amplifier. However, the earphones can help you hear better because they filter out background noise. This makes them suitable to be used in noisy environments. The amount of distortion in earphones is directly proportional to the power that is driving the speaker.

There are three types of earphone connectors. The most common is the jack that connects the earphone to the amplifier; the last is the earphone jack that connects to the user’s earphone plug. People who want to make long distance calls can use a Bluetooth earphone (which is much like a cordless telephone) rather than using the standard earphone. Earphones with rechargeable batteries are also available.
