    NOTE: if the two wires doesn't Look isolated or they have color, then it means that they are coated so you need to remove it By sand paper or flame

      what if the aux cord has 3 wires in it? A red, green, and copper wire. I got it from an old pair of headphones. How should I connect it?

      @@cjprocker ok that's strange, didn't know there was copper wire with no insulator in aux cord but it's possible that it has left channel , right channel and ground but I didn't try it so

      Do you know a specific audio cord that I could buy that is like the one he used? I can’t find any good audio cables, all of the ones I found at my house the inside wires are super super tiny so I can’t get a good connection

    you may not see this, but can i use a wire coated with some school glue as substitute for copper wire?

      you can use the glue wire - but that might be tedious to build

    where does the power supply come from?

    • @rhettallain
      @rhettallain  2 года назад

      there is no power supply. When you speak, that makes vibrations in the air that pushes the cup and makes the audio signal - so I guess your voice is the power source.
      Oh, also the computer amplifies the signal some.

      as long as there is a coating on the wire. If it's bare copper wire, then no

    How does it work?

    • @AkshayDattaguru
      @AkshayDattaguru Месяц назад

      and how do more coils affect efficiency? Is it a linear relationship?

    • @hohsisterofbattle
      @hohsisterofbattle 10 дней назад

      The coil is an inductor. Watch this if you don't know what that is: ruclips.net/video/ySx84Ca7BFQ/видео.html
      Electric current passing through the coil creates magnetic fields. Magnetic fields cause the cone to attract or repel the magnet, which makes the cone vibrate. The vibrations of the cone make vibrations in the air, which is sound.
      More windings = more inductance, which makes the speaker louder, but also less responsive. Higher frequency audio gets cut off by adding too many windings, so more windings = lower maximum pitch. That's why bass speakers are big and treble speakers are small - a bass speaker trades off being able to play high frequencies vs being able to drive a larger cone.
      The main problem with this speaker is the magnet is directly attached to the cone directly. It can still vibrate because the plastic is flexible, but the vibrations are very small. If you attached the magnet to a surface and suspended the speaker cone above it, the sound would be huge.

    This is my favorite thing to do, Need help with this kind of idea for a vintage disk cutter, more help pls.. ?? I have fun replicating speakers, but not sure how to drive it unless u wrap the wire around a nail. as the coil would get very hot if not in an isolated chamber.. so dont leave it on long.. although plastic would have somewhat of a temperature that could deal with it. I would think a milk container would stand the heat though, Nice detailed video with the items, Description and applicant is very clear, Nice video, keep makeing these..
