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 mobile computing device includes one or more digital signal processors, each configured to receive a respective digital signal, one or more amplifiers, each configured to receive a respective digital signal, and one or more output generators configured to receive an output of a respective amplifier, and a battery configured to supply power to at least the amplifier(s). The digital signal processors include an intelligent current limiter. The intelligent current limiter is configured to determine a power consumption limit based on a battery voltage of the battery, a battery current limit defined by a battery current budget for operation of at least the amplifiers, and an efficiency of the amplifiers. The intelligent current limiter is configured to determine a predicted power consumption by the amplifiers based on voltages of the digital signals, a gain of each of the respective amplifiers, and an admittance of each of the respective output generators. The intelligent current limiter compares the predicted power consumption with the power consumption limit and adjusts the gain setting(s) of one or more of the digital signal processors based on the comparison prior to supplying the respective digital signals to the amplifiers.
