Abstract: A method of monitoring speaker temperature for speaker protection starts by generating a low level inaudible noise signal and injecting the low level inaudible noise signal in an audio signal. The voice coil resistance estimate that estimates a resistance of a voice coil of a speaker is then computed. The voice coil resistance estimate changes while the speaker is being driven by the audio signal that includes the low level inaudible noise signal. The temperature estimate is then computed based on the voice coil resistance estimate. The level of the audio signal may be adjusted based on the temperature estimate. Other embodiments are also described.

Abstract: Method to perform thermal monitoring of an electro-mechanical actuator included in a device starts by receiving an in-field calibration temperature from a temperature sensor included in the device. The device may also receive an in-field calibration resistance from a resistance calculator included in the device. A calculated thermal coefficient of resistivity of the electro-mechanical actuator is then computed using an equation that relates the calculated thermal coefficient of resistivity to the in-field calibration temperature. The calculated thermal coefficient of resistivity changes based on the in-field calibration temperature. The equation includes parameters that are stored in the device. A temperature estimate of the electro-mechanical actuator is them computed based on the calculated thermal coefficient of resistivity. Other embodiments are also described.

Abstract: Digital signal processing microphone occlusion detection is described that can be used with a noise suppression system that uses two types of noise estimators, including a more aggressive one based on two audio signals (such as for non-stationary noises) and a less aggressive one based on one audio signal (such as for stationary noises). Decisions are made on how to select or combine the outputs of the noise estimators into a usable noise estimate, based on an occlusion function. The occlusion detection may alternatively be used to trigger an alert to users of multi-microphone audio processing systems, such as smart phones, headsets, laptops and tablet computers. Other embodiments are also described and claimed.

Abstract: Method of throttling a pilot tone for thermal monitoring of an electro-mechanical actuator starts by computing a power estimate based on a driving signal. A first temperature estimate is then computed based on the power estimate. The pilot tone may be generated by adjusting a level of the pilot tone based on at least one of the power estimate or the first temperature estimate. The pilot tone is injected into the driving signal to generate a driving output signal that is outputted by an electro-mechanical actuator. Other embodiments are also described.
