Small paper cups are of great use---simple handmade loudspeaker

What should I do if I want to transmit the sound farther but don’t have a professional amplifier? The most direct method is to put two hands around the mouth in a C shape. If you have some conditions, you can take a piece of paper and roll it into a tube shape to achieve the amplification effect by gathering the sound. If you have a little more conditions, you can use simple tools to assist. No professional required, just a small paper cup. Sound is produced by vibration and is conducted through wires. Very simple, but effective.
