On this day in 1915, the first practical application of moving-coil loudspeaker was invented by Peter Jensen and Edwin Pridham in Napa, California. The design brought together an electroacoustic transducer that produced sound in response to an electrical audio signal input—the same electro-dynamic principle that drives virtually every modern loudspeaker you use in your car, in theaters, and in your home.

The two inventors, fond of latin, translated their invention of the first open-air amplified sound or, the “great voice” into the Latin equivalent: Magna-Vox. The invention of the modern loudspeaker inspired further developments that greatly influenced the way we listen to music today.

To honor the invention that allows us all to listen out loud, we’re sharing some of the songs that frequently make it onto playlists throughout the Sonos office.  Subscribe on Spotify to listen to the playlist on Sonos, or create your own version of the mix using the track list below.
