Phonographs were the primary means of listening to music in the 1930s. These devices used a rotating disc or cylinder to play recorded sound. The discs or cylinders were made of wax or plastic and had a groove that contained the sound waves. A needle would follow the groove and vibrate, which would cause a diaphragm to move and produce sound.
Radios
Radios were another popular way to listen to music in the 1930s. These devices received radio waves that were transmitted from radio stations. The radio waves were converted into sound waves by a speaker.
Jukeboxes
Jukeboxes were coin-operated machines that played music. These machines were often found in public places, such as bars, restaurants, and dance halls. Jukeboxes typically had a selection of 10-20 songs, and users could select the song they wanted to hear by inserting a coin.
