The loudspeaker, as in the dynamo and electric motor, uses the priciple of electrical induction in a conductor through movement inside a magnetic field.
The sound information (from any source) is conveted to constantly varying electrical signals, these are amplified and fed to a coil at the speaker.
In simple terms, the current in the coil produces a magnetic field which varies as the sound varies and this then forces a soft iron rod, which is connected to the speaker baffle (large sheet of cardboard that produces the sound waves) to move in and out, so causing waves in the air around it, which is sound.

How loudspeakers work?
In sound reproduction, device for converting electrical energy into acoustical (sound) signal energy that is radiated into a room or open air . The part of the speaker that converts electrical into mechanical energy is frequently called the motor, or voice coil. The motor vibrates a diaphragm that vibrates the air in immediate contact with it, producing a sound wave corresponding to the pattern of the original speech, music, or other acoustic signal.This is how loudspeaker work.
Will a 3 phase motor work on grounded B phase?
If the motor is connected to an ungrounded delta supply service there will be no effect on the operation of the motor. If the motor is connected to a wye system supply service and the B phase grounds out, the motor's overload protection would take the motor off line from the electrical supply.
