how is sound produced in a human larynx and a loudspeaker
Answers
In human, the voice box or larynx produced the sound. It is at the top of the windpipe. Two vocal cords are stretched throughout the voice box in such a way that it leaves a narrow slit between them for the passages of air. When lungs force air by the slit, the vocal cords start vibrate and produce sound.
At the upper part of a loudspeaker, there is a metal cone. The cone's outer part is faster to the surface of the circular metal rim of loudspeaker. The inner surface is fixed to an iron coil. After connecting the loudspeaker to a stereo, electrical signals feed by the speaker cables into the coil, it turns the coil into a temporary magnet. The electromagnet attracts or repels the permanent magnet when the electricity flows back and forth through the cables. This moves the coil back and forth by pulling the speaker cone and pushing it. Like a drum skin vibrating back and forth, the moving cone pumps sounds out into the air.
