摘要： A mobile device with orientation aware audio mapping capability is disclosed. The mobile device has an aux speaker, a loud speaker, a sensor for device orientation detection, and a processor (or processors) coupled to the sensor and the speakers. Depending on the device orientation, the processor sends a mapped audio output to the speakers. The mapped audio output may be a mono audio signal or a stereo audio signal. The stereo audio output signal may be a stereo audio output signal with a balanced or biased audio power distribution between the aux speaker and the loud speaker.

摘要： A system includes a plurality of channels, a parameter calculator, and an equalizer. Each channel receives a plurality of input signals that represent an input to a speaker. Each channel generates real and imaginary components of a transfer function of the speaker based on the plurality of input signals. The parameter calculator calculates a plurality of parameters of the speaker based on the real and imaginary components of the transfer function received from each channel. The equalizer adjusts the input to the speaker based on the parameters.

摘要： The invention relates to an electronic device that includes a wake-up system that operates at a substantially low power level and is applied to wake up the electronic device from a sleep mode. The wake-up system comprises a sound transducer that converts a received sound signal to an electrical signal and a keyword detection logic that preliminarily identifies a speech energy profile that corresponds to at least one of a plurality of keywords in a part of the electrical signal. In some embodiments, a keyword finder is further activated to identify with an enhanced accuracy whether the at least one keyword exists in the part of the electrical signal, and generates a wake-up control to activate a host of the electronic device from its sleep mode.
