Mechanical devices were designed to use mechanical components and movements to perform specific tasks efficiently and reliably. These devices relied on gears, levers, and other mechanical parts to generate motion and achieve the desired output.
Bearings are like invisible heroes inside mechanical devices because they make such mechanical devices to move right from their internal positions.
Electronics Devices are those devices which are made from semiconductors like transistors fet mosfet amplifiers and ic's and other p-n junction devices. while mechanical devices are those devices which follow the mechanical principle such as strain gauge , machines and robot etc.
Sound energy is mechanical energy. No devices are required to make a conversion.
