Light-emitting diodes, or LED's, have recently become a popular alternative to other lighting technologies, because of their numerous advantages. Therefore, I wonder if the same may happen with sound-producing semiconductors; if they shall ever be as feasible as are light-producing semiconductors.
Currently, sound-producing semiconductors do exist, and the most notable type are piezoelectric buzzers, but the quality of their sound, from my experience, is nowhere near the quality of the sound of traditional electronic loudspeakers, so I now ask: will sound-producing semiconductors ever be a viable alternative to traditional speakers, as they become more efficient and advanced, as semiconductors usually do, or will traditional loudspeakers always be superior? What does everyone else say about that?
