The device Thomas Edison invented to play records is called the phonograph. Here's how it works:
1. A phonograph has a rotating cylinder or disc where sound is recorded.
2. A needle, also known as a stylus, is placed on the surface of the record.
3. When the record rotates, the needle vibrates according to the grooves on the record.
4. These vibrations are then converted into sound by the phonograph's amplification system.
5. As a result, the recorded sound is played back through speakers, allowing people to listen to music or other audio recordings.
Overall, the phonograph revolutionized the way people listened to music and recorded sound, laying the foundation for future audio playback devices.
