Generator
No, I don't think so. The term "generator" is used for devices that convert mechanical energy (movement) into electricity.
Mechanical devices mostly symbolize the parts, joints, rigid structures in it... they mostly symbilize the tough mechanical components therefore call as mechanical :)
Trackball
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.
generator
Electric motors and generators are electromagnetic devices that are the opposite of each other. Electric motors convert electrical energy into mechanical energy, while electric generators convert mechanical energy into electrical energy.
A generator converts mechanical energy into electrical energy, while a motor does the opposite - it converts electrical energy into mechanical energy. Both devices work because of electromagnetic induction, which is when a voltage is induced by a changing magnetic field.
A lever is a mechanical device.
