How a record is made and how it makes sound

How is a

vinyl record

made and how does it make sound

step 1: a master recording is made

step two: a lacquer is placed on a record cutting machine; as it rotates, electric signals from the master recording travel to the cutting head (stylus or needle) which etches a groove in the lacquer

step three: the lacquer is coated in metal (silver or nickel) to make a metal master (metal record)

step four: use metal record to make a stamper (negative version of original recording)

step five:

stamper place hydraulic pre vinyl sandwic the two (steam the plastic as pushes an imp the recording

ed in a ess with the ched between m softens stamp pression of g)

step six: stiffened with cool water and trimmed into a circular disc shape, tested before put on the market

step seven:

the stylus and the tone arm from the record player travel across the vinyl in an arc, the vibrations travel along a metal strip and wires in the tonal arm to the cartridge, it receives vibrations, converts them into electrical signals in a magnetic field, carried along wires to the amplifier, enhances power of the signal which is converted back to sounds and come out the speakers
