Abstract
An electroacoustic apparatus with an optical energy conversion function is provided. The electroacoustic apparatus includes an optical energy converter for converting optical energy into electrical power. The electroacoustic apparatus further includes a signal generator and a flat speaker. The signal generator receives a signal from a sound source and generates a sound signal according to the received signal. The signal generator sends the sound signal to the flat speaker, and the flat speaker makes a sound according to the sound signal. Aforementioned operations are all performed by using the electrical power generated by the optical energy converter or a power stored therein.
