DC motor-Armature
Moving coil Loudspeaker-________.
Please answer the question correctly.....No irrelevant answers needed ❌
Answers
The relation between first pair and second pair is given below
DC motor - Armature
Moving coil Loudspeaker- Voice coil
• The two devices perform similar functions. The principle of working of both DC motor and Moving coil Loudspeaker is similar.
• The current in the Rotar (armature in motor ) and voice coil in Loudspeaker generates magnetic field which applies a force on permanent magnet of a DC motor or speaker.
• In a speaker, the force replaces the coil and attached cone similarly in DC motor , the force rotates the shaft. Both produce vibrations that we perceive as sound .
• Though speaker has an impedance matching cone which improves the efficiency of energy transfer to air whereas in motor this happens to some extent by accident.
