Abstract

A method and a portable electronic apparatus for adaptively adjusting a playback effect of speakers are provided. The portable electronic apparatus includes a speaker enclosure volume adjusting device and a processor coupled to the speakers and the speaker enclosure volume adjusting device. In the method, the processor detects a usage demand for the portable electronic apparatus and accordingly determines an audio mode. Based on the determined audio mode, the processor selects and activates multiple speakers, and adjusts an enclosure volume of at least one of the activated speakers, so as to change an audio frequency range of the at least one speaker and an overall audio frequency range covered by the activated speakers. Finally, the processor plays an audio through the activated speakers.

Dependent claims

A method for adaptively adjusting a playback effect of speakers, applicable to a portable electronic apparatus having a plurality of speakers, wherein the portable electronic apparatus comprises a speaker enclosure volume adjusting device and a processor coupled to the speakers and the speaker enclosure volume adjusting device, the method comprising:

detecting a usage demand for the portable electronic apparatus, and accordingly determining an audio mode by the processor;
activating at least one tweeter and a woofer among the speakers, and adjusting an enclosure volume of the at least one tweeter by using the speaker enclosure volume adjusting device based on the audio mode by the processor, so as to change an audio frequency range of the at least one tweeter and an overall audio frequency range covered by the at least one tweeter and the woofer, wherein the enclosure volume of the at least one tweeter is expanded to increase the audio frequency range of the at least one tweeter;
and
applying an audio setting corresponding to the audio mode to the activated speakers, and playing an audio through the activated speakers by the processor.
