IN a loud speaker there are two magnets. one permanent magnet that always has its northpole pointing in the same direction , and one electro magnet that can change its magnetic field in direction and magnitude. IF both northpoles point into the same direciton ,the speaker cone is pushed out, if both point in opposite directions the speaker cone is pulled in. The direction and magnitude can be controlled by the current passing through the electro magnet.
You should use a ferromagnetic material, such as iron or steel, to make an electromagnet. These materials have strong magnetic properties that are necessary for creating a powerful electromagnet.
Electromagnets are not used in commercially available loudspeakers due to unlinear sound reproduction, noise induced by the electromagnet current and cost. A permanent magnet with a moving coil in the magnet gap is far superior to an electromagnet considering these three parameters.
The exceptionally strong and steady magnetic field reacts with the alternating field created by the alternating current produced by the audio current flowing in what is known as the voice coil. The Voice Coil is physically attached to the cone that moves the air so you can hear the pressure wave that simulates the current wave-form.
A loudspeaker contains a metal coil, known as an electromagnet, that creates a magnetic field when an electrical current passes through it. It is the action of the electromagnet that is responsible for converting electrical energy into audible sound.
Increase the number of coils in the electromagnet. Use a stronger magnetic material in the core of the electromagnet. Increase the current flowing through the wire winding of the electromagnet.
magnets!
electromagnetically
lg ks360 does have a loudspeaker !
No.
yes it does
up your neighbour's loudspeaker?
No, Loudspeaker is an output device.
The duration of The Loudspeaker is 1.12 hours.

An electromagnet drives the stereo speaker to provide the sound.
