    Abstract: A portable electronic device having a speaker module is provided. The speaker module includes: a speaker unit; a back chamber; a channel coupled between the speaker unit and the back chamber; and a porous material filled inside at least a portion of the front chamber, the back chamber, and/or the channel, for improving and extending bass performance and relieving a channel effect caused by the channel. Moreover, the portable electronic device is advantageously able to compensate a resonance degradation caused by the porous material.

    Abstract: The invention provides one sound producing system including a speaker, a driving circuit and an audio controller. The speaker is used for producing an audible sound. The driving circuit is connected to the speaker. The audio controller is configured to receive an input audio signal and pre-amplify the input audio signal with an amplify gain to obtain a pre-amplified audio signal; operate a multiband dynamic range control on the pre-amplified audio signal to obtain an output audio signal; convert the output audio signal to a driving voltage; provide the driving voltage to the speaker through the driving circuit; detect over the driving circuit to obtain at least one excursion parameter to determine an estimated excursion of the speaker in response to the driving voltage; and adjust the amplify gain according to the estimated excursion.

    Abstract: An electronic apparatus and a method for activating a specified function are provided. The electronic apparatus includes a speaker, an audio signal processor and an application processor. The audio signal processor senses a variation of an acoustic condition of the speaker. The application processor is used for: generating a logic high or low signal in response to the sensed variation of the acoustic condition; interpreting the logic high or low signal as a control signal; and performing an instruction corresponding to the control signal.
