The Difference Between Speakers And Motors And Generators

‌Speakers‌: Convert electrical signals into sound signals, which belongs to the principle of motors.
‌Motors‌: Convert electrical energy into mechanical energy to drive equipment to move.
‌Generators‌: Convert mechanical energy into electrical energy, usually used to generate electricity.
Speakers do not operate in a "generator" state during use, but are used as "motors" to generate sound through the interaction of magnetic fields generated by electric current with fixed magnetic fields. If a speaker is used as a microphone, its generator principle can be used to work.
