Speakers frequency range

loudspeakersEach speaker can reproduce a given frequency range. In some common usage typically use a speaker called the full-range speakers, because it has a relatively large frequency range, for example, can play 80-15000 Hz. Full-range Speakers are commonly used in portable radios, transistor radios, radio tubes, old console radio or television.

Loudspeaker

A loudspeaker is a device that converts low-frequency electrical signals into sound. The task of the speaker is to enable the air in periodic oscillations – which in turn brings in the human ear drum to vibrate.

To convert the electrical signals into sound waves are displaced almost exclusively membranes into mechanical vibrations, which also gets the air to the membrane in motion. These membranes will normally act as a piston radiator, ie that the entire membrane is moved smoothly.

Fuses

Various FusesFuses are often used in electronic circuits and devices. They consist of glass or ceramic cylinder with a metal cap at the end. Either exposed or fuse wires are sometimes embedded in quartz sand. This is used to eliminate electric arc when burning through the wire.
