We made working headphones that showcase our identity. My design was having my family history. My dad'd country is on my left side and my mom is on the right side. In the middle is me! There is a Chinese, United States and a Philippines flag at the top. To make the headphones, we had wrapped wire in a coil with 100 loops leaving 2 long pieces out so it will connect to the audio jack and a magnet is in the center of it.
The way the headphones works is when the audio jack is plugged into the music device, it sends alternate electrical current. It travels through the coil of wire and makes a magnetic field. This magnetizes the coil and the real magnet and the coil will be repelling and attracting. This makes it move the sound vibrations into the air. |
