How do speakers work? Incredibly small, yet impressively loud

Ғылым және технология

Speakers weigh less than a dime but can be heard throughout a massive room. How do they make such intricate sounds while being so small? This fundamental lesson gets into the components of a smartphone's speaker as well as their function.

    What amazes me is how people figured out which amount of current produces which sound... The fact that that little piece of material moving back and forth can create such intricate sounds is mind blowing

    They didn't have to. A microphone is the exact opposite of a speaker. It has a thin metal plate that vibrates when sound hits it. That plate then moves an electromagnetic field to make pulses of electrical current. The current is sent to a speaker (which as the video showed) vibrates at the same frequency producing sound. The only difference is the speaker is electrically amplified to make the sound loud enough to hear.

    Exactly. It also sounds far less marvellous when you realise that sound is literally just a longitudinal wave made by an object vibrating. Electromagnetic induction had also been known for quite a while, so it was only a matter of time before someone linked them together.
