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.

Handheld electronic apparatus, sound producing system and control method of sound producing thereof

An audio and video broadcasting apparatus includes a plurality of sound signal capturing devices, an image capturing device, a controller, and a speaker. The sound signal capturing devices capture a plurality of sound signals. The image capturing device obtains a display image. The controller is configured to: divide the display image into a plurality of display regions; establish a correspondence between the disposition positions and relative positions of the display regions; receive a playback setting command of a selected region, and set a playing weight of each of the display regions according to the playback setting command; and adjust a volume playback setting corresponding to the sound signals according to the playing weight of each of the display regions and the correspondence, and generate an output sound signal according to the volume playback setting and the sound signals. The speaker performs a sound playing action.
