It sounds more like you are hitting the starter again after the engine is running.
The distance between the two sides of an individual coil of and AC armature winding id termed the coil pitch.
A traditional speaker produces sound waves when a current is passed through a coil near a magnet. The current varies with the amplitude and frequency of the desired sound. As current passes though the coil, it is attracted to and repelled from the magnet. A cone of paper, plastic, bamboo, or other durable material is attached to the coil, so as the coil makes its movements the paper moves with it. The paper pushes and pulls against the ambient air creating compression sound waves.
Coil tapped humbuckers definitely sound different than real single-coils. You can get usable clean tones with coil tapped humbuckers, but it won't be the same.
the pitch of a coil referes to the angle or degree at which the coils slant. in example you will have a different pitch in the thread of metric and imperial screws. also rough and fine thread. hope that helped
coil span or coil pitch is defind as the distance mesured in terms of armature slots(or armature conductors) between two sides of a coil.
Electrical energy to sound energyExampleSpeakerA coil of wire(voice coil) is placed (inside the cone) in magnetic field produced by a strong permanent magnet, the signal to converted is applied to the coil, so a magntic field is produced due to electric current in the coil. The coil system and permanent magnetic field interacts, so mechanical motion is produced and it causes the coil to move to&fro and it touches the cone, therby reproducing sound from the electrical signal..
HUMBUCKER SOUND IS HIGHER AND DARKET
A speaker makes sound by rapidly vibrating a paper cone or diaphragm. There is an electromagnet attached to the diaphragm. When current flows through the coil one way it becomes a magnet . Since there is a permanent magnet behind the coil, the coil is pulled toward the magnet. When the current is shut off, the diaphragm springs back to neutral. When current flows the other way, the coil pushes away from the magnet. This cycle is repeated thousands of times in a second and creates sound that corresponds to the electrical signal that it is sent. A dynamic microphone uses the same arrangement of a diaphragm attached to a coil near a magnet. The process is just the opposite. Instead of using electricity to make sound, sound is used to make an electrical signal that can be recorded. Incoming sound waves push the diaphragm in and out which drives the coil towards and away from a magnet. An electrical current is created as the coil moves through the magnet's field. This current is a signal that corresponds to the sound received by the microphone. As you can see, an electromagnetic coil is central to the operation of a speaker and a microphone. The magic of the coil is that it can act as a variable magnet, changing both in intensity and polarity. It also changes motion to electricity and electricity into motion.
Sound waves are longitudinal waves. These would vibrate a diaphragm which has been attached with a coil kept in a magnetic field. As the coil vibrates then current is induced. This is how sound wave gets changed into electric current.
The coil produces a magnetic field. When power is applied to the wire in the coil, the result is a magnetic charge. This magnetic charge is part of how the speaker produces sound.
With the speakers' electromagnetic coil!
Sound is made by pushing air with the cone. A coil of wire is attached to the cone. The "sound"current is passed through the coil. Any current running through magnetic flux causes the coil and cone to move. The larger the magnet the louder the sound. A strong permanent magnet is used. Electromagnets are not used, however
