Abstract

The invention provides a sport Bluetooth earphone. The sport Bluetooth earphone comprises a sound card module, an earphone protocol module, a control module, a voice driver module; wherein the earphone protocol module comprises the logical link control and adaptation protocol (L2CAP) and the radio frequency communications protocol (RFCOM-M); the control module comprises an audio noise reduction system; the audio noise reduction system extracts high-quality audio signals based on audio data, including extracting an audio data set X=(x1, x2,..., xn), including n audio data points, and extractinghigh-quality audio data through the way of selecting the center point. The sport Bluetooth earphone provided by the invention significantly improves voice sound effect, reduces voice damage, reducesnoise component more, greatly enhances user comfort and voice sound effect, and enhances user experience.

Description

technical field [0001] The invention relates to the technical field of bluetooth earphones, in particular to a sports bluetooth earphone. Background technique [0002] Bluetooth headset is to apply Bluetooth technology to the headset, so that users can avoid the entanglement of cables, and it is more convenient and free to use, and they can talk in various ways freely. good tool. [0003] However, the existing sports bluetooth earphones are not only complicated in structure, but the battery and the bluetooth module are mostly placed in the cavities of the left and right earplugs. The noise method mainly adopts the spatial pre-classification method and the coherent function method to achieve noise reduction and sound quality enhancement through filtering, but this method is likely to cause speech damage. How to reduce noise more, cause less speech damage, and improve sound quality has become the current urgent needs. Contents of the invention [0004] In order to solve t...
