| titleOfInvention | Active noise reduction control system based on single-microphone Bluetooth headset and Bluetooth headset |
| abstract | The application discloses control system of falling an noise initiatively based on single microphone bluetooth headset, including set up be used for in the earphone main part gather the ambient noise and will pick up the conversation sound wave and the ambient noise transmission that get and give the conversation and the initiative noise reduction module of bluetooth main control chip, set up in be used for in the earphone main part through receiving the speaker module that the reverse signal of telecommunication of noise that bluetooth main control chip generated and the reverse sound wave that sends the suppression noise were fallen and is fallen, the conversation and the initiative noise reduction module and speaker module are connected with bluetooth main control chip, and bluetooth main control chip carries out the reverse signal of noise that filtering signal processing generated and transmits the speaker module to ambient noise, this control system of falling an noise initiatively realizes simultaneously that the conversation is fallen and fall the initiative noise reduction, design space diminishes, and the cost step-down has strengthened falling and has fallen and talk effect, The experience of the user is better. |
