Headphone with Multiple Reference Microphones ANC and Transparency - A simplified explanation of the abstract
This abstract first appeared for US patent application 18450942 titled 'Headphone with Multiple Reference Microphones ANC and Transparency
Simplified Explanation
The patent application describes an ear cup housing that includes multiple reference microphones, an error microphone, and a speaker. A processor is used to drive the speaker for acoustic noise cancellation and transparency by processing the microphone signals. Additionally, the processor performs an oversight process by adjusting the reference microphone signals when wind noise events and scratch events are detected. The reference microphones are positioned on the perimeter of the ear cup housing, which is joined by an outside face and an inside face.
- The ear cup housing includes reference microphones, an error microphone, and a speaker.
- A processor drives the speaker for acoustic noise cancellation and transparency by processing the microphone signals.
- The processor adjusts the reference microphone signals in response to detecting wind noise events and scratch events.
- The reference microphones are positioned on the perimeter of the ear cup housing.
- The ear cup housing has an outside face joined to an inside face.
Potential Applications:
- Noise cancellation headphones or earphones
- Communication headsets for clear audio transmission in noisy environments
- Hearing aids with improved noise reduction capabilities
Problems Solved:
- Reduction of background noise interference during audio playback or communication
- Minimization of wind noise and scratch noise for improved audio quality
- Enhanced transparency to allow external sounds to be heard while wearing headphones or earphones
Benefits:
- Improved audio experience with reduced background noise
- Clearer communication in noisy environments
- Increased comfort and convenience for users wearing headphones or earphones
Original Abstract Submitted
An ear cup housing has several reference microphones, an error microphone and a speaker. A processor drives the speaker for acoustic noise cancellation and transparency, by processing the microphone signals, and performs an oversight process by adjusting the reference microphone signals in response to detecting wind noise events and scratch events. In another aspect, the ear cup housing has an outside face that is joined to an inside face by a perimeter and the reference microphones are on the perimeter. Other aspects are also described and claimed.
