Introduction: Beatniks by Garret and Dylan

These headphones are pleasing to make!

Step 1: Materials

You will postulate these materials:

3-arm lengths of 28 AWG wire.

2 theme cups / South cups

3.5 mm two-channel jack AUX plug (with terminals)

Music rootage (iphone, ipod, etc.)

4 Neodymium magnets

Any type of sandpaper

1 Office Depot highlighter

1 Roll of Electrical Tape

1 pair of scissors or Wire Cutters

Step 2: Summary of Parts

You will pauperization a plastic cup because it will act as your diaphragm. We chose the paper cup because it was more compromising and it vibrated more else cups made out of different materials such as plastic and styrofoam. The diaphragm is what vibrates to move air and sound. The copper electrify is accustomed connect the stop to the AUX cable which connects to the sound source. We chose 28 AWG because the less AWG, the more thicker the wire is. The sandpaper is used to sand off the edges of the wire so it buttocks atomic number 4 exposed. The magnets are used to produce an permanent attraction field in the diaphragm. The music source is obviously where the medicine will hail from. The highlighter is what you will use to wrap the wire around to make the vocalize coil. Electrical magnetic tape is used to secure parts of the headphones such as the voice coil. Wire cutters are used to trim the wire.

Footfall 3: Assemblage

Catch up your AUX plug and make a point the terminals are showing.

Hand-build the copper wire loosely around the highlighter 40 times. Form sure about 30 cm is shown for for each one end of the wire. To finish the coil, tighten the coil by wrapping both ends of the wire around the volute. Next Amandine Aurore Lucie Dupin both sides of the wire. Make fated some ends are fully exposed. Then grab your paper cupful and cut half off so the as is just left-hand. Lay the voice coil dispirited in the middle of the cup (outside) then put a attractive feature inside the middle of the voice curlicue. Then put a magnet within the cupful. You should wealthy person something like the image supra.

Then grab other cup and repeat the steps to make the other slope of the headphone.

When you are done making both sides, solder peerless end of the voice whorl to another ending of other voice handbuild. (Necessitate a parent for help)

Then grab the other ends of the voice coils and thread them through the AUX plug terminals. Plug the AUX cable into a phone or device and play a song to test if the headphones act upon. If they don't turn back your connections and make a point the wires aren't moving each opposite because they will cancel each other out if they are in contact. Once you are confident that your headphones work, solder the wires to the AUX plug. (ask a parent for help)

Step 4: Magnet Positioning and Diaphragm Assembly.

The reason wherefore a lasting magnet is requisite in the middle of the voice coil is so the temporary magnet (voice coil) attracts and repels from the static magnet which causes the vocalise coil to produce sound. We decided to chose 2 magnets one on each side of the transfuse because neodymium magnets are really strong so we felt that 2 should be good. For the diaphragm, we chose to follow how the contraceptive diaphragm affected the sound quality and found that the Dixie cup felt solid and the music produced from it didn't birth that many issues.

Step 5: Explaination

Our Speaker should work because,

  • We successfully wrapped our voice coil and it is the right size up for our magnets. The coiled telegram becomes the voice coil which acts as a parttime magnet inside the speaker.
  • Our cable is fully sanded and securely attached to our aux plug. The sanding exposes the telegraph ends which connect to the AUX plug and the other speaker.
  • Our diaphragm (plastic transfuse) is non damaged, the bottom fully moves low and dorsum.
  • We chose 40 coils because when we time-tested 30 coils out, the noise was tranquillity and when we proved 50, the noise was loud and soft. Thusly we decided to antitrust use 40 coils since it worked best.
  • The magnets produce a perpetual magnetic branch of knowledg which changes sign. The mutual opposition changes when there is an alternating current which is when the magnets attract to all other and then repel, which is what causes the alternating current running through the voice coil and starts to vibrate which causes the diaphragm to impress and make sound.

Step 6: Plug and Period of play

  • Sanding the telegram on some ends exposes the wire so it can connect to the AUX fire hydrant terminals and the other headphone speaker. If you Don River't sand, so there wouldn't be any connection.
  • Sound waves are produced when the voice coil vibrates inside the diaphragm (which is the plastic loving cup).
  • An alternate current is created when the voice ringlet (temporary magnet) starts to attract and push back from the static magnet (neodymium magnets).
  • During our observation, we noticed that we could actually hear lyrics from our headphones. We also noticed that there weren't any noises when we reached high pitches and almost of the time, the audio quality was unmoved away the bass of the music.

Step 7: Troubleshooting

Q:What if my headphones don't work?

A:Make a point that the wires aren't touching each otherwise or else they will cancel from each one different tabu. This also means to check that the wires twisted roughly the terminals aren't touching each other. If information technology still doesn't turn, try adjusting the voice coil. You Don River't want it to be snug along the bed of the loving cup soh it will be able to vibrate.

Q:What if I hear the music but it is faint?

A:Try to make sure all connections are certified and make sure everything is linked together. It could be something like the wires weren't soldered together properly, operating theater a wire wasn't secured to the AUX plug.
