On the speaker system is a component that carries the electronic signals,save in CDs, tapes, and DVDs, then returned again to the form of actual sound we can hear. In this article, will explain how a speaker to do the process. They will also be discussed why the speakers are designed differently and how these differences lead to different effects on quality. Speaker is an amazing technology that provides a very large impact on our culture. But besides all that, the speakers actually just a very simple tool.


Making sound

Basically, the speaker is the final interpreter engine, the reverse of the microphone. Speaker brings electrical signal and turn it back into vibrations to create sound waves. Speaker produces vibrations similar to that produced by a microphone that recorded and coded on the tape, CD, LP, and others. Traditional speakers do this process by using one or more drivers.


Diaphragm

Drivers produce a sound wave by vibrating a flexible cone or diaphragm quickly. Cone is usually made of paper, plastic or metal, attached to a larger end at the suspension. Suspension or surround, is hundreds of flexible material which moves cones, and the metal frame on the drivers, called basketball.


The tip of the arrow on the cone serves to connect the cone, voice coil. Coil is didempetkan in basketball by the spider, which is a ring of flexible material. Spider coil held in position while pushing to move back freely and so on.
