Loud speaker usually has two electromagnets (or a permanent magnet and an electromagnet).
When an audio signal in the form of an electric signal with desired frequency is applied to both electromagnets in opposite direction at same time so that they act as magnets with same polarities facing. This makes them repel with the given frequency, thus producing sound.

What makes the wind howl?
the winds amplitude vibrates on the object(sand, buildings and houses) and the vibration causes a audiobilyion which is a sound or vibration that is hearable to the human ear. this act is called senaterilarl.
What has particles that vibrates at right angles to the direction of the wave?
Photons oscillate (vibrate) along an axis that is perpendicular to the direction of the photon's travel. Photons are responsible for all electromagnetic radiation, including visible light, invisible light (infrared and ultraviolet), X-rays, radio waves, and magnetic waves. . When all photons in a beam of light oscillate in same direction, that is called polarized light.
Do Pure metals generally have high temperature coefficient?
As the metal forms mostly solid their formation of atom are close compare to liquid and gases so their atom vibrates at less rate they have relative less area to vibrate compare to liquid and gases so metal can withstand to a very high temperature
What are some quartz uses?
to make radio circuits, radar, television, telephone circuits, ultrasonic equipment, and quartz oscillator plates in electronic products; as prisms, wedges, and lenses in optical spectrographs

What is in a longitudinal wave?
When something vibrates, like a loudspeaker, it compresses the air and increases the pressure of the air when it moves out. When the loudspeaker moves in it creates a partial vacum and a decrease in air pressure. The increase/decrease in air pressure is propagated thru the air (or any medium),as a longitudinal wave, by pushing the air in front of it. The part of the cycle which produces the decrease in pressure is called a "rarefacation" of the air.
