Abstract: Illustrative embodiments enable a MEMS transducer to quickly recover from, acoustic overload events by quickly resetting signal processing circuitry downstream from a MEMS transducer. An acoustic overload sensor detects occurrence of an acoustic overload event, and triggers a reset circuit to operate a set of switches to rapidly drain charge from a corresponding set of capacitances within the transducer, or within the signal processing circuitry, thereby resetting the signal processing circuitry more rapidly than would occur if said transducer or circuitry were allowed to recover on its own.

Abstract: The present disclosure provides systems and methods for audio signal generation. The method may include obtaining first audio data collected by a bone conduction sensor; and obtaining second audio data collected by an air conduction sensor, the first audio data and the second audio data representing a speech of a user, with differing frequency component. The method may also include generating, based on the first audio data and the second audio data, third audio data, wherein frequency components of the third audio data higher than a frequency point increase with respect to frequency components of the first audio data higher than the first frequency point. In some embodiments, the method may further include determining, based on the third audio data, target audio data representing the speech of the user with better fidelity than the first audio data and the second audio data.

Abstract: A dual omnidirectional microphone array noise suppression is described. Compared to conventional arrays and algorithms, which seek to reduce noise by nulling out noise sources, the array of an embodiment is used to form two distinct virtual directional microphones which are configured to have very similar noise responses and very dissimilar speech responses. The only null formed is one used to remove the speech of the user from V2. The two virtual microphones may be paired with an adaptive filter algorithm and VAD algorithm to significantly reduce the noise without distorting the speech, significantly improving the SNR of the desired speech over conventional noise suppression systems.

Abstract: A system comprises an ear-worn electronic device configured to be worn by a wearer. The ear-worn electronic device comprises a processor and memory coupled to the processor. The memory is configured to store an annoying sound dictionary representative of a plurality of annoying sounds pre-identified by the wearer. A microphone is coupled to the processor and configured to monitor an acoustic environment of the wearer. A speaker or a receiver is coupled to the processor. The processor is configured to identify different background noises present in the acoustic environment, determine which of the background noises correspond to one or more of the plurality of annoying sounds, and attenuate the one or more annoying sounds in an output signal provided to the speaker or receiver.

Abstract: A linear motor magnet assembly for use in a loudspeaker unit, with a fixed base actuator component and a membrane actuating element, the membrane actuating element having a linear excursion axis. A first auxiliary magnetic element and a second auxiliary magnetic element are present, the first auxiliary magnetic element providing a first auxiliary spatial magnetic field with a major axis aligned with the linear excursion axis. The second auxiliary magnetic element is fixedly connected to the membrane actuating element of the linear motor magnet assembly and has a second auxiliary spatial magnetic field, the second auxiliary magnetic field overlapping the first auxiliary spatial magnetic field and being substantially similarly oriented as the first auxiliary spatial magnetic field over a first predetermined excursion range of the linear motor magnet assembly.

Abstract: Embodiments generally relate to a signal processing device for on ear detection for a headset. The device comprises a first microphone input for receiving a microphone signal from a first microphone, the first microphone being configured to be positioned inside an ear of a user when the user is wearing the headset; a second microphone input for receiving a microphone signal from a second microphone, the second microphone being configured to be positioned outside the ear of the user when the user is wearing the headset; and a processor. The processor is configured to receive microphone signals from each of the first microphone input and the second microphone input; pass the microphone signals through a first filter to remove low frequency components, producing first filtered microphone signals; combine the first filtered microphone signals to determine a first on ear status metric; pass the microphone signals through a second filter to remove high frequency components, producing second filtered microphone signals; combine the second filtered microphone signals to determine a second on ear status metric; and combine the first on ear status metric with the second on ear status metric to determine the on ear status of the headset.
