Webbdevice exploiting this effect is called “thermophone”. It has a wide bandwidth and does not contain any mechanically vibrating parts. The first thermophone based on a metallic film was discovered at the end of the 19th century by Braun1. In 1917, Arnold and Crandall2 theoretically explained the thermal origin of sound in thermophones.
