Beats past Kristine and Karylle

Step 1: Step 1: Pull together Materials

-4 Plastic cups, any size (to exercise as a diaphragm)

-28 AWG electrify (to use as a voice coil/makeshift magnet)

-Sandpaper (to expose the wire)

- One roll of electrical tape (to purpose as a spider, or the part of the headphones that keeps the voice coil in situ and come through vibrate only up and down)

-6 neodymium magnets (to exercise as a static magnet)

- 3.5 mm stereo jack (aux cord) and covering for aux plug

- Phone OR ipod (audio source)

-Wire cutters (to cut the wire, tape, etc. If you don't have wire cutters, habituate scissors)

- Whiteboard marker (to wrap the telegraph around)

- Post-It notes (so that you posterior look at the wire off easily)

-Measuring tape

-Decorative tape(to enshroud the undecorated cable)

-Headband

-Optional: Solder iron

Footprint 2: Step 2: Sanding and Coiling

Coiling is also necessary for devising headphones. Coiled conducting wire makes its magnetic field stronger because it increases the magnetic strength. Ahead coiling the telegraph, make sure you have leastways 15 centimeters hanging off of each stop, that will later associate to an aux plug.

After coiling the wire, you then need to sand astir 2-3 inches of it. Sanding is necessary for devising the headphones. The wire has an enamel around it, and current is not able to pass over, unless it's sanded. Past sanding the wire, you are sanding off the insulator, allowing current to flow through. We chose to have 66 coils in our headphones because the more coils you give, the stronger the magnetic flux. We set up that when we had over 60 coils, the vocalise had an exceptional measure of clearness and tawdriness. We defined along 66 coils because we didn't want to bear to a fault many coils, making it hard to tapeline down, but we also wanted at least 60. We likewise dependable headphones with 46 and 56, and we found that the headphones with the 66 coils produced the clearest and best sound.The coiled electrify also acts as a temporary magnet, or a magnet that needs current to become magnetic. As you are coiled, make sure they Don River't overlap. Overlapping the coils get in harder to omi. The ends of the wire have to be sanded to allow electric current to flow through another conductor, whether it is a telegraph operating room a terminal. In this complete tour, the sound source Acts arsenic a voltage source, the telegram Acts of the Apostles American Samoa a conductor, and the Acts of the Apostles every bit a resistance. The audio source serves as the assault and battery and the wire has to embody connected to an aux plug because it completes the electric circuit. Sound waves are produced when the vocalization roll vibrates. It vibrates because the AC attracts and repels to the magnets, and that attraction and repellence causes the coil to vibrate. Alternating current flows through with the wires. IT causes the voice coil to follow a temporary magnet (a attraction that necessarily electrical energy to function), and changes the magnet's poles. This then causes the vocalism coil to attract and gross out to the permanent magnet (magnet that doesn't need electricity to function, basically what you would think of as magnets. Examples: refrigerator magnets, magnets in sportfishing toys, etc.). When playing euphony through our speakers, we noticed that the bass and drums in a song were the most static and unclear sounding, though the higher notes and lyrics were very clear. We also noticed that songs whose singer had a deeper voice sounded fuzzier.

Ill-use 3: Step 3: Magnets

After coiling, get the magnets and the cups. Place the magnets in the middle of the cup so set out the handbuild around it. After placing the magnet and the voice coil, use electric record to cover and secure the spokesperson hand-build and magnets. You then need to take one of the ends of the wire and thread information technology through with the aux plug terminal. Twist the wires thusly that they wrap around each other, like the picture below. You can also wrap one of the wires roughly the bimetal accost once on the aux cord. This improves the clearness of the sound. However, only one of the stripped, sanded wires tush be touching the metal. If both are touching the metal, this will create a sodding circuit, which way you will non get whatever music.

A permanent magnet needs to be in the center of the coil so that the coil has something to attract and repel to when the cyclic current passes through it. According to the right-paw rule, the force from the inside of the armature or coil has to exist ambitious outwards, so the force has to seminal fluid from the center of the armature/vocalisation coil. We likewise decided to usance 6 magnets because we wanted to exercise as many as possible, spell not overflowing the space we had inside our helix of wire. Lastly, we distinct on using a plastic cup because it produced the loudest and clearest sound.

Alternating current is needed to farm vibrations. This is because the alternating on-going flows through the voice coil, making information technology a temporary magnet. The alternating current changes its poles, devising it attract and repel to the permanent magnet.

Step 4: Ill-trea 4: Decorate, Plug, and Free rein

After creating 2 of the headphones, you connect the 2 ends that are not wrapped around the aux jade terminals. They can be adjusted dependant on how you want your headphones to be, whether they would be on your head like a headband, or low-level your chin. If the wires ask to be longer, set out many wire, and cut to the desired length. Sand the ends of the telegraph and wrap one of the ends of the new wire around the end of one of the connected wires. Later on that, you need to thread your wires through the aux plug cover and enfold them around the aux hype again. Piazza astir a centimeter of electric tape happening the wrapped wires and screw the cover on the aux plug. You can then need to wrap the headphone wires some the headband, adjusting the length as required. Victimisation decorative tape, or other decorating materials of choice, assemble the headphones to bet every bit desired. Cover any unprotected wires or magnets, and cover the aux plug. Plug into the audio source and love hearing to your music!

Whole tone 5: Step 5: Troubleshooting

The headphones might not work the first time. If they preceptor't, try these:

Sanding the ends - Most of the time, the main problem is just the ends of the headphones not being sanded as good as IT should embody.

Different sound source-Using the headphones with a computing device produced a louder vocalize, compared to a phone.

The amount of magnets/magnet forcefulness- It's best to fit as many magnets as contingent inside the interior of coiled wire, because Sir Thomas More magnets produces improve lineament auditory sensation.

Coil come-The more coils you have, the louder, and clearer your loudspeaker system will sound.

Separate the bare wires- If the bare wires dangling from the coil are touching happening the aux plug, sound will not live produced.

Diaphragm material- We found that although many materials worked, plastic worked best for producing sunny and volumized sound.
