This post specifically pertains to Lamphone technology.
These days privacy is far different from the dictionary meaning. In recent days, losing privacy primarily remembers hacking/compromising any device which contains important or potential information. Moving onto the next step, researchers develop a new method that can be used by the attackers to listen to our conversations just by staring at a light bulb in the room.
To start with, lamphone is a device developed by the researchers which uses small vibrations of the light bulb caused by the sound waves to retrieve audio produced in the room. Basic innards of regular microphones(as described below) are required to know about lamphone.
There is a three-step process which involves three components in a microphone, a device which converts sound waves into an audio signal, they are
Firstly, a diaphragm- which contains a thin piece of material through which sound waves (air pressure fluctuations) pass and create a mechanical motion to the diaphragm.
