you need to have magnet wire if so go on
depending how big you need it if you are fixing a sub/speaker you need to cut out the cone and spider then take out the coil and round some paper put it in the space where you took the coil out. then tape it at that size take it out and wrap the magnet wire very tight and very close together prob. 2 layers or 3 depends on how it was before so check the original coil. then put it back in and buy a new cone spider.
if your making one then wrap the magnet wire around paper towel role or soda can or axe can. but remember to put paper on the can or what ever son the coil keeps its shape
hopes this helps
What else can I help you with?
What is the purpose of the coil in a speaker?
The coil in a speaker, often called the voice coil, is used to convert electrical signals into mechanical vibrations (sound). When an electrical current passes through the coil, it interacts with the magnetic field of the speaker, causing the coil to move back and forth rapidly, which in turn creates sound waves.
Why don't my rear speakers work?
wiring problem! check wire connection form radio to speaker,if ok, check speaker coil connection, speaker coil may be loosed.
Why do speaker have magnet?
The magnet is part of the 'motor' of the sub. The coil inside the magnet has alternating current running through it. The coil acts as an electromagnet and pulls itself up or pushes itself down moving the cone of the speaker. The bigger the magnet, the stronger the magnetic field inside the speaker where the coil is.
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 does an electro magnet work in a speaker?
An electromagnet in a speaker consists of a coil of wire wrapped around a core material. When an electrical current passes through the coil, a magnetic field is produced, causing the coil to either attract or repel from a permanent magnet. This movement of the coil creates vibrations that produce sound waves, which are then amplified and projected by the speaker.
Will using one coil on a dual coil speaker damage it?
with only one coil hooked up, a dual voice coil speaker will suffer a loss in reference efficiency of about 3dB (only half the coil windings are being energized) as well as a significant shift in its Thiele/Small parameters. This renders any enclosure calculations inaccurate unless you remeasure the speakers parameters with only one coil hooked up. Failure to account for the different parameters of a dual voice coil speaker with only one coil powered can result in very poor performance.
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.
How does a field coil speaker work?
A: A speaker has a magnet and the wire is suspended in a zone by a cone whereby +/- current will make the coil move up or down moving the coil and moving the cone causing air displacement as waves of pressure that our ears can detect as sounds in our brains.
Can a moving coil loud speaker be used as a moving coil microphone?
Yes, but with vey low sensitivity and poor frequency response.
A spinning coil of wire is what moves the cone in a speaker?
When an electric current is passed through the coil of wire in a speaker, it creates a magnetic field that interacts with a permanent magnet. This interaction causes the coil to move back and forth, which in turn moves the cone of the speaker and produces sound waves.
How does a audio speaker work?
An audio speaker works by converting electrical signals into sound waves through the movement of a diaphragm. When an electric current passes through a coil of wire in the speaker, it creates a magnetic field that interacts with a permanent magnet, causing the coil to move back and forth. This movement of the coil vibrates the diaphragm, creating sound waves that we hear as sound.
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.
