How sound energy is converted to electrical energy?

Answer 1

A normal microphone does that.

It converts sound energy to electrical energy this energy level is used as an output using same energy level amplified or it could be used to record those same energy output and pattern too be played again.

But sound has such a small amount of energy as energy loses are very high that you seriously can't produce a power plant that works on sound.

Answer 2

Sound energy can be converted to electrical energy through a device called a microphone. A microphone contains a diaphragm that vibrates when exposed to sound waves, converting the sound energy into mechanical energy. This mechanical energy is then converted into electrical energy through a process involving a coil and magnet, generating an electrical signal that corresponds to the original sound wave.

Answer 3

It has been calculated that one big cheer from the spectators in a football stadium has enough energy to boil a cup of water. Now, although heating water takes quite a bit of energy, this actually isn't very much from so many people. A microphone works by sound vibrations moving a coil past a magnet. The output from the microphone will be around 10mV and is capable of delivering a few milliamps. In other words, not very much energy at all. This is the problem with converting sound energy - there is very little of it concentrated in a specific area to capture and therefore it is hard to get enough power to light up even the smallest light. There are optically active materials that glow when they are vibrated or hit. Material of this type might begin to glow faintly if it is placed in a strong sound field. Even so, this conversion still requires a lot of sound energy and is probably not the next big green energy idea.

Answer 4

I have an idea to produce more sound which can cause more distrubance so that electricity can be produced easily.

First we have to record the sound and place it ina vaccum(glass box where air cannot pass through it.Then play the sound a little bit of noise can be heard by our human ear.

Then attach a psethescope head to it to produce more sound two ends are connected to a speaker where we have too produce current.So, I think this will help you people to move forward

Thank you alot to read this article.................

so try this at home and produce noise.....................

Answer 5

Sound contains a common computer language called binary. This code consists of on and off switches or 1's and 0's, 1=on 0=off. When you speak into a microphone it takes this code and makes it into electrical signals which can the be transmitted through the airwaves or to a speaker. Binary is a universal language that can be used in many applications, even what you see on your screen is made possible by binary code.

Answer 6

The sound vibration is typically used to cause a tiny magnet to move in a tiny

coil of wire. As we know, a magnet moving in a coil of wire produces a voltage

between the ends of the coil.

A good example of such a device is the one known as a "microphone".

Another good example used to be the "phonograph cartridge", but there's

hardly anybody left who knows what those are.

Answer 7

As longitudinal waves fall on the diaphragm it vibrates to and fro. This is in attachment with a coil which surrounds a magnetic material. So as the coil vibrates then magnetic flux linked with the coil changes and so emf is induced due to electro magnetic induction. This is how sound energy is changed into electrical energy

Answer 8

Basically this is the process of the operation of a microphone. By vibrating a membrane via sound waves through a magnetic field it produces electrical energy .

Answer 9

A speaker transforms electrical energy to sound energy, through electromagnetic motion, motor effect.

Answer 10

You could run it through a microphone.
