The common magnetic loudspeaker is, fundamentally, a fairly simple machine. A static magnetic field is generated by a permanent magnet, and a membrane is mechanically connected to a coil. When a varying electrical current is passed through the coil, this causes the coil to move due to the magnetic field, vibrating the membrane and producing sound.
[Mattosx] put this theory into practice with a simple 3D-printed speaker.The post A Mostly 3D Printed Speaker appeared first on FeedBox.
