Is there any possibilities to convert sound energy into electrical energy?if so how?

Answer 1

That is currently how many microphones work. It is a vibrating magnet over a coil generating electricity.

Answer 2

As several answerers have said, it's been done...you do it every time you talk into a telephone. There are several ways to do this.

One can use a diaphragm to pick up the sound vibrations. These are then converted into electric pulses by a magnet on the vibrating diaphragm and wrapped wire that forms a coil just below the magnet. When magnetism is pulsed around a wire, a similar pulse of electricity is formed.

Or one can use a special crystalline material called piezoelectric material that creates electrical pulses when impacted...like from the vibrations of a diaphragm. [See source.]

Although you didn't ask it, the reverse process, changing electrical pulses into sound energy, is also done. Both the magnet and piezoelectric processes are reversible...creating sound from electricity. That's how you can enjoy the cool sounds on your iPod or the awesome vibrations from your woofer.

Answer 3

yes it is, but the gains will be very limited, till you have an abundant source like probably women chatting in a room, but that would also not be of much help.
You need a large diaphragm, attached to a magnet, which is in turn moveable inside a coil, the principle on which speakers work.
Get the sound source to move the coil, and a current will be generated, the intensity and stability of the current produced will depend upon the sound frequency being applied to the diaphragm and the intensity of the sound fallin on it. irregular sound will not produce a uniform current.

Answer 4

With Electro - acoustic converters (just a fancy name for speakers, which convert electric current into mechanical oscillations, and microphones, which convert mechanical oscillations into electric current).

There are several methods used:
1) Electromagnetic and electrodynamic converters;
2) piezoelectric converters;
3) magnetostrictive converters;

Answer 5

Sound skill might want to be switched over into almost the different type or skill (with the exception of nuclear skill). however, air isn't a good transmitter of skill and convalescing skill from noise polution would not be very possible. The loudest recorded noise (that I really have research) changed into the blast from a Saturn rocket at Cape Canaveral, Florida. The sound waves (rarefactions and condensations) varried from close to vacuum to 2 times(?) atmospheric rigidity. you would possibly want to harness such massive sound rigidity yet would not favor to be everywhere close to it. I also study that a Frenchman(?) invented a huge compressor-pushed police whistle just about as massive as a motor vehicle that generated a noise so low in frequency that he might want to not hear it however it became his insides into jelly from the vibrations. also even although a huge symphony orchestra can paintings up a sweat perchance taking section in allegro FFF! they purely impart some watts of skill to the air contained in the live performance hall. so that you're ideal in idea yet might want to actual stumble on a better powerful (and safer?) technique of acquiring skill. solid success.

Answer 6

There are many types of transducers that convert sound energy into electrical energy, like microphone, guitar transducers, ultrasound transducers (like are used in ecography). Most of these transducers use the pizzo-electric effect of a special crystal that converts sound vibration into electricity.

Answer 7

First answer correct. A Microphone does this. Also, Telephones. You can even use a Speaker, just attach your wires and speak close to the speaker without touching the inner part and you will get a very small electrical output.

Answer 8

As far as I know all energies can be converted form one form to another. Sound also and the numerous answers above are all correct.

Answer 9

ya ,obviously as of without u would not have been talking to ur frnd on the telephone. basically,when you speak,you induce pressure waves in the medium.the sound wave travels as consisting of alternate compressions and rarefactions.considering the example of a mike, when u speak on a mike,you induce mechanical vibrations in the diaphragm attatched with a coil of wires which is kept in a strong magnetic field.Because of the relative motion between the magnetic field and conductor(coil of wires),a current is induced in the coil which is the required conversion .

Answer 10

Isn't that called SONICS and hasn't it already been done? Or do you maybe mean HARMONICS?
