ACTIVE NOISE REDUCTION HEADPHONES AND METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240135913 titled 'ACTIVE NOISE REDUCTION HEADPHONES AND METHOD
Simplified Explanation
The patent application describes active noise reduction (ANR) headphones that use multiple signals to generate a compensation signal for the loudspeaker, improving the quality of sound for the user.
- ANR headphones generate a sound signal
- Include a loudspeaker, an external microphone for ambient noise, and an internal microphone for residual noise
- Have an acceleration sensor to detect accelerations
- Controller generates a compensation signal for the loudspeaker based on ambient noise, residual noise, and acceleration signals
Potential Applications
The technology could be applied in various industries such as aviation, automotive, and consumer electronics for improved audio quality and noise cancellation.
Problems Solved
The technology addresses the issue of unwanted noise interference in audio playback, providing a more immersive and enjoyable listening experience for users.
Benefits
- Enhanced sound quality - Improved noise cancellation - Better user experience
Potential Commercial Applications
- Aviation headsets - Car audio systems - High-end headphones
Possible Prior Art
One possible prior art could be the use of noise-canceling headphones with only ambient noise compensation signals, without considering residual noise and acceleration signals.
Unanswered Questions
How does the technology adapt to different environments and user preferences?
The patent application does not provide details on how the ANR headphones adjust the compensation signals based on changing noise levels or user settings.
What is the impact of the acceleration compensation signal on overall sound quality?
The application does not discuss the specific influence of the acceleration signal on the performance of the ANR headphones.
Original Abstract Submitted
anr headphones generate a sound signal, and include a loudspeaker, an external microphone configured to detect an ambient noise signal, and an internal microphone configured to detect a residual noise signal within an ear canal of the user. moreover, the anr headphones have an acceleration sensor configured to generate an acceleration signal indicative of accelerations experienced by the anr headphones. a controller of the anr headphones is configured to generate a loudspeaker signal based on a composite compensation signal. the composite compensation signal is a combination of an ambient noise compensation signal based on the ambient noise signal, a residual noise compensation signal based on the residual noise signal and an acceleration compensation signal based on the acceleration signal.
