the speaker can handle. High power performance can create heat of around 250°C(Langford-Smith, 1957, p. 835) hence the need for a metal chassis. It helps to dissipate heat and is sufficiently stiff. Another choice has to be made in choosing a stamped or cast metal basket. The latter tends to be more precise and maintains its stability. Aluminium cast frames are usually chosen for large woofer cones which have to deal with heavy magnets. On the one hand, the chassis has to be as strong as possible but on the other hand it must not influence speaker cone movement. Therefore it needs to be as open and durable as possible. Well-vented design assures heat radiates away from the voice coil. The last factor is self-resonance. To counter this the chassis has to be acoustically dampened. 1.6. Voice coil…

In essence, Tesla coils are a high-voltage, resonant transformer circuits. They consist of the six major components (Behrend 1), namely: Primary transformer Tank capacitor Spark gap Primary coil Secondary coil Toroid Figure 1: Tesla coil (diagram) A primary transformer is a step-up transformer that takes the line voltage of the AC source and steps it up to a range between 12 kV and 50 kV at 60 Hz (Johnson 4). The efficiency of this transformer is largely dependable on the construction…

The main point of this passage is to inform people on the science behind the Tesla coil. A Tesla coil In scientific terms can be called a high frequency air transformer, the name doesn't mean it turns air into electricity. While most people understand that tesla coils have larger copper wires with a donut shape, called a top load, at the top which is made of conductive metal. Some of the largest tesla coils can hold up to a million voltz, voltz are a measurement of electricity.…

tiptoed into the lab, wondering what kind of experiment was going on, and found himself in an organized mess. Beams of light, dust particles floating lazily within, streamed through the windows constituting the outside wall of the room, and warmed a workbench covered in pencil sketches, machine parts and the head of a sleeping mechanical rooster-man. Approaching carefully, Rex was slightly disappointed to find that what he at first thought was a cyborg chicken-human was actually a regular guy…

The Tesla Coil is a very enthralling invention created by Nikola Tesla in 1891. The high voltage, high frequency output of the amazing machine can cause strange effects in all sorts of materials. Though not a well known invention, the Tesla Coil plays a gigantic role in television and radio today. How does it work? What materials are used to make it? How can it be used today? And overall who was Nikola Tesla? The Tesla Coil is comprised of the following materials: a chassis, frame, cabinet or…

If your AC starts blowing hot air it may be due to the fact that it is freezing up. The coil is an important part of cooling your house up. The coils works by taking the warm air from your home and releasing them outside. If the coils in your AC unit become too cold they can freeze up. When your coils are frozen the ice can cause blockages, this results in you AC unit to run without cooling the home, whilst using a lot more electricity than usual. Why Do the Coils Continually Freeze Up? One…

I was crying uncontrollably as my mother entered my bedroom. I was a mere two years old, so I had no thought of what was happening. All I could see is my mother with a disturbed look on her face looking at me. No one knew what was happening, was I going to die? We went to the hospital and the doctor realized that i had discolored veins. I had blood poisoning. I was born on February 1st, 2002 the first child of my parents. My full name is Austin Thomas Richardson, however my name came from many…

INTRODUCTION Flexi-Coil Ltd., a division of CNH Global, is Canada's largest farm implement manufacturer and has become a key employer in the Saskatoon area since its establishment in 1952 by the farming brothers Emerson and Kenneth Summach. [1,2] In 1997, Flexi-Coil sold 35% of its market shares to New Holland Agriculture. In 1999, New Holland became a brand of CNH Global. [3] Later, in the same year, CNH Global completed the purchase of the global Flexi-Coil business. [2] In 2013, CNH…

Dirty Evaporator Coil Can Affect Your Furnace If you notice your furnace running more than usual even when it's not much colder outside, the problem might be obstructed airflow. When air can't flow through the system easily, your furnace has to work harder and longer to meet the setting on the thermostat. Clogging can cause more serious issues too, such as overheating and stressing parts. It's important to find the source of the restricted airflow and have it fixed. One possible cause is the…
