SIGNAL PROCESSING DEVICE, MICROPHONE DEVICE, SIGNAL PROCESSING METHOD, AND RECORDING MEDIUM - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240347033 titled 'SIGNAL PROCESSING DEVICE, MICROPHONE DEVICE, SIGNAL PROCESSING METHOD, AND RECORDING MEDIUM
Simplified Explanation: The patent application describes a signal processing device that analyzes the relationship between signals from two microphones, one inside the ear canal and one outside, to determine when to start processing sound signals based on specific conditions.
- The device determines if a relationship between signals from two microphones meets a condition before processing sound signals.
- Processing of sound signals begins when the condition is met and continues even if the condition is no longer satisfied, as long as a different condition is met.
- The first microphone is inserted into the user's ear canal, while the second microphone is positioned outside the ear canal.
Key Features and Innovation:
- Analysis of signals from two microphones to determine when to process sound signals.
- Ability to continue processing sound signals based on different conditions, even if the initial condition is no longer met.
- Differentiation between signals from a microphone inside the ear canal and one positioned outside.
Potential Applications:
- Hearing aid devices
- Noise cancellation systems
- Speech recognition technology
Problems Solved:
- Efficient processing of sound signals based on specific conditions.
- Improved user experience with audio devices.
- Enhanced noise filtering capabilities.
Benefits:
- Enhanced sound processing accuracy.
- Better user comfort with audio devices.
- Improved noise cancellation performance.
Commercial Applications: Potential commercial applications include:
- Hearing aid devices for individuals with hearing impairments.
- Noise cancellation systems for improved audio quality in various environments.
- Speech recognition technology for hands-free communication.
Prior Art: Prior research in signal processing devices for audio applications may provide insights into similar technologies and approaches.
Frequently Updated Research: Stay updated on advancements in signal processing technology for audio devices to enhance the performance and capabilities of the patented device.
Questions about Signal Processing Device: 1. How does the device differentiate between signals from the two microphones? 2. What are the potential challenges in implementing this technology in real-world applications?
Original Abstract Submitted
a signal processing device determines whether a relationship between a first signal and a second signal satisfies a first condition, the first signal being based on an output of a first microphone inserted into an ear canal of a user, the second signal being based on an output of a second microphone positioned outside the ear canal. the signal processing device starts processing relating to transmission of a sound signal when it is determined that the first condition is satisfied, and that continues the processing, even after the first condition is not satisfied, during a period in which a second condition that differs from the first condition is satisfied.
