How does speaker voice coil work?
The voice coil is a coil of wire wrapped around a cylinder that accepts the current from the amplifier. This current causes the voice coil to react with the speaker magnet which moves that cylinder up and down. The speaker cone is attached to the cylinder which produces air pressure when it moves creating sound.
How does the speaker cone moves to produce different sounds?
The center of the speaker cone is attached to one end, which gets driven back and forth by the moving coil. This cone is held at its edges by an airtight suspension or surround. As the cone moves, it pushes and pulls the surrounding air; by doing so it creates pressure waves in the air, called sound.
How does a coil make sound?
Voice coil is placed in magnetic field and attached to speaker cone. This whole structure forms perfect piston that moves in and out to produce compression and rarefaction in the air that we call as sound. For different frequency, voice coil will vibrate to produce sound of that frequency.
What makes a good voice coil?
Coil Size Matters Well, the larger you make the voice coil, the more power it can handle—but at the same time, it also generates more heat. Smaller coils can be a little more resonant, but larger coils tend to have better control. Some speakers have to have larger coils.
What does a voice coil do in a microphone?
Both microphones and loudspeakers utilize voice coils to convert sound to audio or audio to sound, respectively. To be more specific, dynamic microphones have voice coils, and most loudspeaker designs do as well.
What are the main components of a speaker?
A summary of the parts that make up a speaker, and some of the critical design issues is shown here.
- Yoke. the back of the loudspeaker.
- Magnet. The driving force of the speaker, but magnets are available in a wide variety of specifications and sizes.
- Front Plate.
- Chassis.
- Voice coil.
- Suspension.
- Cone.
- Surround.
How does a voice coil work?
The voice coil is really just creating an electromagnetic field that fluctuates in intensity, causing it to move to and away from the natural magnet on the back of the speaker. This movement takes the paper cone with it, pushing air and creating waves, resulting in sound.
What is a moving coil on a speaker?
The moving coil presses and pulls on the speaker cone and vibrates the air in front of the speaker. This creates sound waves via a driver that vibrates the diaphragm. Cite This! HowStuffWorks.com Contributors “What’s a voice coil on a speaker?”
What is a dual voice coil on a subwoofer?
(January 2008) A three-inch diameter dual voice coil from a subwoofer driver. A voice coil (consisting of a former, collar, and winding) is the coil of wire attached to the apex of a loudspeaker cone. It provides the motive force to the cone by the reaction of a magnetic field to the current passing through it.
How do I replace the voice coil on my speaker?
You can do this by either cutting it or peeling it Straighten out the cone neck where the old voice coil was Take out the old dust cap by cutting it or dissolving it Then use the new layout and measure the new dimensions to help you install a new voice coil We should warn you that voice coils need to be exact when replacing them.
