WebHow does a speaker work Physics GCSE? A loudspeaker makes use of the motor effect to produce sound. Variations in the AC electric current supplied to the device causes variations in the magnetic field produced. These variations cause the cone in the loudspeaker to move and the vibrations are transferred to the air particles and generate a sound wave.
