The working principle of the speaker is an electric motor, because the speaker uses the principle of the force exerted by the energized conductor in the magnetic field to convert the electrical signal into an acoustic signal, so the principle is the same as that of the electric motor.

The speaker uses the principle of the force exerted by the energized conductor in the magnetic field. The principle of converting electrical signals into acoustic signals is the same as that of electric motors.
The speaker is not in "generator" state during use, but in "motor" state.
The principle is: the audio current enters the coil (voice coil) of the speaker to generate a magnetic field. This magnetic field interacts with the magnetic field of the magnet to generate thrust or suction, which in turn drives the movement of the speaker's paper cone and pushes the air to produce sound. .
This process is to convert the electrical energy of the current into the kinetic energy of the paper cone - so it is the working principle of an electric motor, not a generator.
On the contrary, if a dynamic speaker is used as a microphone, the generator principle of the speaker is used.
