Abstract:
A handheld electronic, a sound produce system and control method of sound producing thereof are provided. The sound produce system includes a speaker, a feedback unit, a gain unit and a compensation unit. The speaker generates audible sound according to an output audio signal. The feedback unit generates a first detected parameter, wherein the first detected parameter represents a detected excursion. The gain unit receives an input audio signal, and amplifies the input audio signal to generate a gained audio signal according to a gain value. The compensation unit receives the gained audio signal and the first detected parameter, and predicts an excursion of the speaker corresponding to the gained audio signal to generate a predicted excursion parameter, and compensates the gained audio signal to generate the output audio signal according to the first detected parameter and the predicted excursion parameter.
