The needle of the sound cartridge is an important part of audio playback devices, designed to convert surface irregularities of vinyl records into sound waves.
The needle moves along the surface of the record, and the surface irregularities cause it to vibrate at a certain frequency, thus allowing the audio data to be read.
This needle is interchangeable and suitable for Audio-Technica AT3600, AT3600L, AT3601, AT3651, AT3650L, AT3650C, AT3650, and AT3626 cartridges.
