ACTIVE LEAKAGE ADAPTION FOR WEARABLE AUDIO DEVICES - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240305923 titled 'ACTIVE LEAKAGE ADAPTION FOR WEARABLE AUDIO DEVICES
The abstract describes a patent application for a wearable audio device with active noise cancellation capabilities.
- The wearable audio device includes at least one speaker, a first sensor to sense sound related to the speaker, a second sensor to sense external sound, active noise cancellation circuitry, at least one active vent, and a processor.
- The active noise cancellation circuitry provides music-compensated sensor signals and ANC signals.
- The processor analyzes the sensor signals and ANC signals to determine if a trigger threshold is met, and if so, sends a control signal to the active vent to open or close.
Potential Applications: - This technology can be used in headphones, earbuds, or other wearable audio devices to provide a better listening experience in noisy environments. - It can be utilized in communication devices for clearer audio during calls or video conferences.
Problems Solved: - Reducing background noise interference in audio playback. - Enhancing the overall sound quality for the user.
Benefits: - Improved sound quality in noisy environments. - Enhanced user experience during audio playback and communication.
Commercial Applications: - This technology can be marketed to consumers looking for high-quality audio devices for personal use. - It can also be targeted towards professionals who require clear audio communication in their work.
Prior Art: - Prior art related to active noise cancellation technology in audio devices can be found in existing patents and research papers in the field of audio engineering.
Frequently Updated Research: - Stay updated on advancements in active noise cancellation technology in wearable audio devices to ensure the latest features and improvements are incorporated into future iterations.
Questions about Active Noise Cancellation Technology: 1. How does active noise cancellation technology work in wearable audio devices?
- Active noise cancellation technology works by using microphones to pick up external noise, then generating anti-noise signals to cancel out the unwanted sound, resulting in a quieter listening experience.
2. What are the key benefits of active noise cancellation in audio devices?
- The key benefits include improved sound quality, reduced background noise, and enhanced user comfort during audio playback.
Original Abstract Submitted
a wearable audio device can include at least one speaker; a first sensor configured to sense sound related to the at least one speaker and provide a first sensor signal; a second sensor configured to sense sound external to the wearable device and provide a second sensor signal; active noise cancellation (anc) circuitry configured to provide at least a third signal and fourth signal, wherein the third signal is a music compensated first sensor signal and the fourth signal is an anc signal; at least one active vent; and at least one processor configured to: receive the first sensor signal, the second sensor signal, the third signal and the fourth signal to determine whether a trigger threshold is met, and if the trigger threshold is met, send a control signal to the at least one active vent to cause the at least one active vent to open or close.
