Dynamics Of The Duke
First, we'll put all the points on "i" and we'll figure out the terminology. Electrical loudspeaker, dynamic loudspeaker, dynamics, a dynamic head of direct radiation is a variety of names of the same instrument of worker to transform electrical variations of sound frequency into air fluctuation, which we see as sound.
Sound dynamics or other dynamic heads of direct radiation you've seen at times. They are actively used in the household electronics. It's the loudspeaker who converts the electrical signal at the outlet of the audible frequency plug into the heard sound.
It should be noted that the CPA (the utility coefficient) is very low and is about 2 to 3 per cent. It's a huge minus, but it's still no better idea.
While it should be noted that other devices exist other than the electrodynamic loudspeaker to convert electrical fluctuation into acoustic fluxes. For example, electrostatic, pesoelectrical, electromagnetic type loudspeakers have been made widely available and used in electronics.
How's the dynamics?
To understand how the electrodynamic loudspeaker works, we'll turn to the drawing.
The dynamic consists of a magnetic system, it's on the back. It has a ring magnet. It's made of special magnetic alloys or magnetic ceramics.
Magnetic ceramics are specially compressed and “specially” powders that contain ferromagnetic substances. The magnetic system also includes steel Fleans and a steel cylinder called a kern. The Flanks, the Kern and the ring magnet form the magnetic chain.
There is a gap between the kern and the steel flange in which the magnetic field is formed. A cable is placed in a lock that is very small. The cat is a hard cylindrical carcasus, on which a thin copper wire is built. That cat's called a sound cat. The sound pot carcas connects to the diffusor, it pushes air, compressing and irradiating the ambient air, acoustic waves.
Diffusor can be performed from different materials, but more often it is made from a pressurized or paper mass. Technologies are not locally available and can be found in motion by diffusers from plastics, metallic paper and other materials.
