Kind Code:
A1
Abstract:
The present invention relates to the technical field of electronic devices. Disclosed are a Bluetooth headset noise reduction method, device and system. The method comprises: when a voice data channel is opened, a terminal sends a noise signal acquisition instruction to a Bluetooth headset; the Bluetooth headset acquires noise signals via a microphone and sends the noise signals to the terminal; the terminal generates reverse phase signals based on the noise signals and sends the reverse phase signals to the Bluetooth headset; the Bluetooth headset plays the reverse phase signals along with music signals or voice signals. The embodiment of the present invention implements noise reduction of the Bluetooth headset on the terminal side through software, enabling the Bluetooth headset to be low in cost, small in size and convenient to carry.
