Limited Edition
Dr. Dre Beats (Detox) What is it made out of?
Aluminum frame to provide rigidness
Sponge in the earmuffs to provide comfort
Copper for wiring
Rubber casing for wires
Information found on:
www.google.com Aluminum Frame Aluminum is extracted from bauxite ore, which is formed by lateritic weathering and accumulation of clay and limestone. It contains minerals like boehmite and diaspore.
Open pit mines use explosives to loosen the soil. Miners shovel the bauxite-rich ore into trucks.
Alumina is extracted from bauxite through the bayer Process, wich includes the use of caustic soda and high temperatures. This alumina is processed into aluminum through electrolysis. Alumina is reduced to aluminum and oxygen through electrolysis in molten cryolite.
Aluminum is very ductle, thus manufscturs are easily able to turn aluminum blocks into specially desined frames. Copper Copper is a naturally occurring mrtal that can be exracted from sulfide and oxide ores 9formed by weathering).
These ores are blasted inot smaller pieces, and put into powder containing only 1% copper.
these powders are then concentrated, creating 15% copper.
After concentration, much melting and puryfing occurs, creating 99% copper andes.
Copper is then transformed into several different shapes, including wire rod, which are used in the headphones. Sponge Sponges are actually organisms that get harvested by speciall trained drivers with large two-pronged
hook and string bag. After they het harvested, they
are sent to a sponge factory to get processed into sunthetic sponge. This process includes submerging sponges in bleach, chemical softeners, and sodium sulphate crystals. Then, sponges get sent to converters, where they are cut and designed to fit their consumers' need. Rubber Synthetic rubber is different fron natural rubber in that it comes from petroleum, coal, natural gas are formed by millions of years of heating and pressurizing ancient organisms. These substances are mainly extracted by mining deposits. These substances are heated at extremely high temperatures until they form crude clumps of rubber. Finally, rubber is molded into certain shapes by heating it and forcing it into a specially designed mold (like wire casing). Once the rubber is added to the headphonesthey can be shiped to the store so prople can bye them What can Be
Recycled in Headphones Can Headphones
Be Trash? Headphones can be thrown in the trash but should be recycled because it can be and it better for the enviorment. Copper- Used copper is taken back my metal industries to be recycled. They can either melt the copper and use it for impure copper pipes, or they can dissolve it in sulphuric acid and purify it, to be used again by electrolysis or used again th another pair of headphones
Sponge- Scraps of recycled sponge can be regenerated into new sponge (for headphones) with specific machinery.
Aluminum- Aluminum can be recycled and re-smelted into new blocks of aluminum. This aluminum is then sent to specialzed industries to be rolled out and converted to cans or more headphone framing.
Rubber- Rubber can be recycled and reused in playgroung surfaces and sthletic tracks. Life Cycle of a Pair of Headphones Bibliography www.google.com
