Speakerphone with differential audio data compensation method
The patent US12069450B2 describes a speakerphone designed to enhance audio quality through advanced signal processing techniques. The speakerphone features a housing that accommodates two microphones with bi-directional polar patterns, an output transducer, and a processor. The processor is responsible for receiving and calibrating the audio signals from both microphones, effectively eliminating contributions from the output transducer in the final processed signal. This configuration allows for improved sound capture and clarity during calls. Additionally, the arrangement of the microphones and transducer is optimized to minimize interference, as they are positioned along a common axis, ensuring effective sound nulling.
The patent also outlines methods for compensating audio data based on the aging state of the microphones, allowing for adjustments that maintain performance over time. The system can incorporate an external microphone to further enhance audio processing capabilities, including echo cancellation for far-end users. The claims emphasize the importance of differential signal processing, where the processor determines differences between calibrated signals from the microphones to refine audio output. Overall, this speakerphone design aims to provide a high-quality communication experience by leveraging sophisticated audio processing techniques and adaptive calibration methods.
