Speaker

 Description of Speaker


Speaker is an electro-mechanical device, which converts electrical signals into sound waves. It is also commonly called loudspeaker.

Speaker back and front side


Working principle


The working principle of the speaker is based on electromagnetic induction. When electric current flows in the speaker's coil, it generates a magnetic field. This field interacts with the permanent magnet and moves the voice coil back and forth. Due to this movement, the diaphragm or cone vibrates and sound is produced.


Main parts


Diaphragm/Cone - The main part to generate sound waves.


Voice Coil - Converts electric current into magnetic force.


Magnet - Reacts with the coil and generates vibration.


Frame/Basket - Supports all the parts. 


Terminals – To connect the speaker to the power source.


Types


Woofer: For deep and heavy sound (Low Frequency).


Tweeter: For high and sharp sound (High Frequency).


Mid-range: For medium frequency sounds.


Sub-woofer: For extremely deep bass sounds.


Uses


Speakers are used in radio, TV, mobile, home theater, computer, musical instruments and sound systems.


👉 In simple words, a speaker is a device that converts the electric waves flowing in your mobile or radio into audible sound. 🎶


Would you like me to make a beautiful chart of it too which shows all the main parts of the speaker with pictures?
