i think, transducers and amplifiers might be used
A microphone converts sound energy into electrical signals. These signals are then transmitted to a recording device or a sound system for amplification and manipulation.
A microphone is a device that converts sound energy into electrical energy. Sound waves cause a diaphragm in the microphone to move, which then generates an electrical signal that represents the sound.
An incandescent lightbulb is an example of a device that converts electrical energy into light and heat. A loudspeaker is a device that converts electrical energy into sound.
A speaker is the device that converts electrical energy into sound energy. An electrical signal is sent to the speaker, which causes a diaphragm to vibrate and produce sound waves that we hear as sound.
A photodetector or light sensor is used to convert light energy into electrical signals, which can then be converted into sound using a speaker or headphones. The electrical signals are amplified and converted into sound waves that we can hear.

Lots of devices do that. A motor will convert electrical energy to mechanical energy (i.e., to movement); a lamp will convert it to light; a speaker will turn it to sound; etc.
1) Sound already has energy, so if you have a sound, you don't need to convert anything. 2) If you strike an object, you'll make a sound - thus converting kinetic energy into sound energy.

A loudspeaker
A simple method is already available and it's called a speaker-you can also use it as a microphone.
