Hey,
I am searching for a transducer which absorbs sound waves and converts it into electric energy.. Is there any device/component available of such type??
please help me.. I need that to carry out my project.
Than you In advance.
The simplest transducer to do that is a microphone.
@ albert: thank you. but Is there any device with larger area for receiving the sound??
coz the microphone is very tiny.
In terms of energy, even for very loud noises, we are talking of very, very small numbers. If it is for a scientific demo project, even a single microphone or a small array should be enough. For producing "real" energy, even a huge tranducer wouldn't produce much. From what I read, the sound pressure for a VERY loud noise would be of around 1W per square meter. Add to that conversion losses, and you won't be able to produce much energy.
