What is a voice coil?
a voice coil is the electromagnet that causes a speaker horn to move in response to the electrical impulses received from the amplifier.
Which electronic components are used in speakers?
Electronic components used in speakers include capacitors, magnets, voice coils, an electrostatic speaker, and speaker wire. These components allow electricity to be converted into audible sound.

What is use of megnetic force in speaker?
The magnetic force in a speaker is used to drive the motion of the speaker cone. When an audio signal passes through a coil of wire (voice coil) attached to the speaker cone, it creates a magnetic field that interacts with the permanent magnet in the speaker. This interaction results in the movement of the speaker cone, producing sound waves.
How do the vibrations of an audio speaker produce sound waves?
When an electrical signal is sent to the speaker, it causes a current to flow through the speaker's voice coil which creates a magnetic field. This magnetic field interacts with the permanent magnet in the speaker, causing the voice coil to move back and forth rapidly. This rapid movement of the speaker cone creates compressions and rarefactions in the air, which are perceived as sound waves by our ears.
Inside a stereo speaker you will find two permanent magnets one on the cone and one near the cone?
The permanent magnets in a stereo speaker are used to create a magnetic field that interacts with the electrical current flowing through the voice coil attached to the speaker cone. This interaction causes the voice coil to move back and forth, pushing and pulling the cone to produce sound waves. The permanent magnet near the cone provides a stationary magnetic field, while the magnet on the cone moves with it to drive the sound production.
What type of microphone is most similar to a speaker?
A dynamic microphone is most similar to a speaker. They both consist of a diaphragm, a voice coil and a magnet.
What is the energy transfer of a loud speaker?
A loudspeaker converts electrical energy into mechanical energy to produce sound waves. When an electrical signal is passed through the speaker's coil, it interacts with a magnet to create vibrations that move the speaker cone and produce sound.
What process occurs when an electric signal is converted to sound waves in a speaker?
When an electric signal is converted to sound waves in a speaker, the signal passes through the speaker's voice coil, which interacts with a magnet to create a changing magnetic field. This changing magnetic field causes the voice coil to move back and forth rapidly, vibrating the speaker cone. The vibrations of the cone produce sound waves that correspond to the original electric signal, allowing us to hear sound.
What is the use of magnet in speakers?
Principle is electromagmnetism. When a conductor cuts magnetic field electricity is induced in the conductor (Fixed magnet). When a magnet is moved near a conductor electricity is generated in the conductor (Fixed conductor). In speakers magnet is fixed and the conductor (in the form of a coil is fixed to the back of the diaphragm) is allowed to move freely. As the coil is fixed to the diaphragm the movements of the coil is reciprocated by the movements of the diaphragm. Our voice induces varying current in the microphone and the same varying current is passed through the coil of the speaker hence it moves in the static magnetic field.
Does a sub-woofer contains motor in it?
No. _________________________ A 'motor' is the section of a speaker that drives the cone. This section consists of the spider, the voice coil and the magnet.
Why does a speaker need an electromagnet not a permanent magnet?
One of the main kinds of speakers needs both. Sound in the form of varying electricity is fed through part of the speaker known as the 'voice coil' which is actually just an electromagnet. Since the electricity in it is varying the magnetism produced by this coil varies too. The voice coil is placed close to a permanent magnet and the voice coil is permitted to move back and forth in response to the electricity going through it. A big cone is fastened to the voice coil to transmit the movements of the voice coil to the air more efficiently. Thus overall the permanent magnet and the electromagnet work together to produce the sound waves that we hear from a speaker. For a more detailed explanation go to the How Stuff Works web site and search for speaker.
Why are magnet used in speaker loudspeaker?
the current flows to the voice coil, and at first the polarity of the current is the same as that of the speaker magnet, causing the voice coil to be pushed away from the magnet pushing the cone outward. then as the current cycles through it becomes opposite from the magnet cauing the voicecoil and cone to be pulled back in
How can a loud speaker make sound energy with electric energy?
A loudspeaker converts electric energy into sound energy using a vibrating diaphragm or cone. When an electric current passes through the speaker's voice coil, it creates a magnetic field that interacts with the permanent magnet inside the speaker, causing the voice coil to move back and forth rapidly. This motion pushes and pulls the diaphragm or cone, creating changes in air pressure that we perceive as sound.
What is the part of a loudspeaker that vibrates to make sound?
a speaker uses a voice coil a coil copper wire and a magnet and pole to vibrate a cone
