SOUND CAPTURING METHOD, MICROPHONE, AND ELECTRONIC DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240259735 titled 'SOUND CAPTURING METHOD, MICROPHONE, AND ELECTRONIC DEVICE
The abstract of this patent application describes a microphone that utilizes a laser self-mixing apparatus and a diaphragm apparatus to detect sound vibrations and convert them into audio signals.
- The microphone includes a membrane that responds to sound vibrations, with the laser self-mixing apparatus and diaphragm apparatus separately configured to detect the membrane's vibrations.
- A method performed by the microphone involves obtaining a first voltage signal using the laser self-mixing apparatus and a second voltage signal simultaneously using the diaphragm apparatus.
- If the first voltage signal is below a preset threshold, it is converted into an audio signal; if it exceeds the threshold, the second voltage signal is converted instead.
Potential Applications: - High-quality audio recording devices - Noise-canceling headphones - Speech recognition systems
Problems Solved: - Accurate detection and conversion of sound vibrations - Improved audio quality in recording and communication devices
Benefits: - Enhanced audio performance - Precise sound detection - Improved user experience in audio applications
Commercial Applications: Title: Advanced Microphone Technology for Enhanced Audio Devices This technology can be used in various commercial products such as high-end microphones, noise-canceling headphones, and voice-controlled devices, catering to audiophiles, professionals, and everyday consumers.
Questions about the technology: 1. How does the laser self-mixing apparatus improve sound detection in the microphone? 2. What advantages does the diaphragm apparatus offer in terms of audio signal conversion and quality?
Original Abstract Submitted
this disclosure provides methods and apparatuses related to a microphone. in an implementation, a microphone includes a laser self-mixing apparatus and a diaphragm apparatus, the diaphragm apparatus includes a membrane configured to respond to a sound vibration, and the laser self-mixing apparatus and the diaphragm apparatus are separately configured to detect a vibration of the membrane. in an example method performed by the microphone, a first voltage signal is obtained by using the laser self-mixing apparatus, and a second voltage signal is simultaneously obtained by using the diaphragm apparatus. if the first voltage signal is less than or equal to a preset threshold, the first voltage signal is converted into an audio signal; or if the first voltage signal is greater than the preset threshold, the second voltage signal is converted into an audio signal.
