Abstract:
A control method of sound producing, sound producing apparatus, and portable apparatus are provided. The control method of sound producing is for a portable device, including the following steps. (a) A first detected parameter indicating a detected excursion of a speaker of the portable device is generated. (b) A second audio signal is generated based on a first audio signal, wherein the second audio signal is generated selectively by compensation according to at least the first detected parameter. (c) A gain value is determined according to at least the first detected parameter and a third audio signal is generated based on the second audio signal according to the gain value.
