The factors that affect the productivity of both camera and drone PATs include. a. base wage increases, perfect attendance bonuses, and the amount a company spends annually per camera/drone PAT on training and productivity-enhancing assembly methods. b. PAT training and experience, base pay increases, warranty claim rates, how frequently workstations are modernized, and the P/Q ratings of the camera/drone models being assembled. c. the size of assembly quality incentives paid to PATs, the size of the fringe benefits package, how the total number of vacation days (not including sick days) for PAT members compare to the all-company average levels, and the amount a company spends annually per camera/drone PAT on training and productivity-enhancing assembly methods. d. P/Q ratings, warranty claim rates, the amount of overtime pay a PAT member receives, and how many cameras/drones are assembled each year. e. the complexity of the company’s camera/drone designs; a company’s cumulative spending for product R&D; the size of the year-end perfect attendance bonus awarded to camera/drone PATs; and the number of camera/drone components.

sound is invisible, but sometimes we can feel it. when a kettle-drum is thumped with a stick that time the tight drum skin moving up and down very quickly for some time and then it pumped sound waves into the air. loudspeakers also work in a similar manner.

components of a speaker:

electromagnet

in order to translate an electrical signal into an audible sound, an electromagnet is used in looudspeakers

  suspension

suspension is used to   center the voice coil in the gap of the magnet and it exerts a restoring force to keep it there. suspension is used to limits the maximum mechanical excursion of the diaphragm and voice coil.

voice coil

voice coil is a coil of wire which is attached to the apex of a loudspeaker cone. it provides the motive force to the cone by the reaction of a magnetic field to the current passing through it.

cone

in a   loudspeaker, a   thin, semi-rigid membrane attached to the voice coil, which moves in a magnetic gap due to which it vibrates   and produced sound. it is known as diaphragm and it can also be called a cone, though not all speaker diaphragms are cone-shaped.

surround

surround is also known as front suspension. surround is used to join the cone to the chassis. together with the suspension it controls the cone excursion, and it is also used to   determine how energy which is   travelling through the cone is absorbed, and how the speaker limits when it reaches the ends of its travel.

dustcap

dustcap is used to protect the voice coil from dust and dirt. it is a part of the cone.

how speaker work

the outer part of the cone is fastened to the outer part of the loudspeaker's circular metal rim. the inner part is fixed to   voice coil that sits just in front of a permanent magnet . when loudspeaker is hooked up to a stereo, electrical signals feed through the speaker cables into the coil. it will convert the coil into an electromagnet magnet . when electricity flows back and forth in the cables, the electromagnet either repels or attract the permanent magnet. this moves the coil back and forth, and it pull and push the loudspeaker cone. like a drum skin vibrating back and forth, the moving cone pumps sounds out into the air.in this way loudspeakers works.
