Then, remove the magnet and tape the wire coil to the bottom of the plastic container.

How do speakers work?| Explore |

Speakers come in all shapes and sizes, enabling you to listen to music on your iPod, enjoy a film at the cinema or hear a friend’s voice over the phone. In order to translate an electrical signal into an audible sound, speakers contain an electromagnet: a metal coil which creates a magnetic field when an electric current flows through it.

How to Solder: 8 Steps (with Pictures)

They come in different thicknesses from around .02" to some really thick stuff you would only use on copper pipe with a butane torch. You use thin solder for detailed work like putting resistors onto circuit boards and thicker solder for joining larger materials like speaker …

Voice coilWikipedia

A voice coil (consisting of a former, collar, and winding) is the coil of wire attached to the apex of a loudspeaker cone. It provides the motive force to the cone by the reaction of a magnetic field to the current passing through it. The term is also used for voice coil linear motors, such as those used to move the heads inside hard disk drives, which produce a larger force and move a longer .

How copper is madematerial, used, processing, steps

The copper ore usually contains a large amount of dirt, clay, and a variety of non-copper bearing minerals. The first step is to remove some of this waste material. This process is called concentrating and is usually done by the flotation method. 3 The ore is crushed in a series of cone crushers.

Hi-fi shops can sometimes also do repairs for you.

Cup Speaker: Physics & Sound Science Activity

The cup pushes air back and forth, creating a sound that travels to your ear. The bare wire itself does not move much air, so it does not make much sound. However, if the coil is attached to a large, low-mass material, it will vibrate that material which, in turn, will vibrate the air, making a louder sound.
