What does a record needle do?

A record needle, also known as a stylus, is a small, sharp object that is used to read the grooves on a vinyl record. The needle is attached to a cartridge, which is in turn attached to the tonearm of the record player.

The needle vibrates as it moves through the grooves of the record. These vibrations are converted into electrical signals by the cartridge and amplified by the amplifier. The speakers then convert the electrical signals back into sound waves, which we can hear.

The needle is made of a very fine material, such as diamond or sapphire. This is because the grooves on a vinyl record are very small and delicate. The needle must be able to follow the grooves accurately without damaging them.

The needle is also very light. This is because it needs to be able to move freely in the grooves of the record. If the needle were too heavy, it would damage the grooves.

The needle is a critical part of a record player. Without it, the record player would not be able to play music.

Here are some additional information about record needles:

  • There are two main types of record needles: moving magnet (MM) and moving coil (MC). MM needles are more common and less expensive. MC needles are more expensive, but they offer better sound quality.
  • The needle should be replaced regularly, as it can become worn over time.
  • The needle should be cleaned regularly to remove dirt and dust.
