Patent attributes
A speaker system includes a speaker, a processor, and an active noise cancellation (ANC) circuit communicatively coupled with the processor. The ANC is configured to apply ANC on audio signals from outside the speaker system to generate a modified audio signal stream through the speaker. The application of ANC is to include generation of ANC signals to interfere with at least part of the audio signals from outside the speaker system in the modified audio signal stream. The processor is configured to determine of low-frequency energy at the speaker system, the low-frequency energy below a threshold frequency. The ANC circuit is configured to, based on the determination of low-frequency energy at the speaker system, perform a corrective action on application of ANC to the audio signals from outside the speaker system.
