Embodiment 1

[0047] like figure 1 As shown, the method for realizing noise reduction of a Bluetooth headset provided by an embodiment of the present invention is applied to a terminal, and the method includes the following steps:

[0048] S11. When the voice data channel is enabled, send an instruction to collect noise signals to the Bluetooth headset.

[0049] Specifically, the voice data channel includes but is not limited to, for example, a music playback channel and a call channel. After the terminal establishes a connection with the Bluetooth headset, when the voice data channel is enabled, the terminal sends an instruction to collect noise signals to the Bluetooth headset through the Bluetooth protocol stack. Command The bluetooth headset picks up the noise.

[0050] S12 , after receiving the noise signal collected by the Bluetooth headset, generate an inverted signal according to the noise signal and send it to the Bluetooth headset.

[0051] Specifically, after receiving the nois...

Embodiment 2

[0054] like figure 2 As shown, the method for realizing noise reduction of a Bluetooth headset provided by the embodiment of the present invention is applied to a Bluetooth headset, and the method includes the following steps:

[0055] S21. After receiving the instruction to collect the noise signal sent by the terminal, collect the noise signal and send it to the terminal.

[0056]Specifically, after receiving the instruction, the Bluetooth headset starts to detect low-frequency noise (100-1000 Hz) in the environment that can be heard by human ears, and collects noise signals, preferably using a noise microphone (when there are at least two microphones) to collect noise Signal. And the collected noise signal is fed back to the terminal through the Bluetooth protocol stack. The Bluetooth headset can collect ambient noise through the microphone and send it to the terminal in real time, so as to achieve the effect of real-time noise reduction. It can also collect ambient nois...

Embodiment 3

[0061] like image 3 As shown, a method for implementing noise reduction of a Bluetooth headset provided by an embodiment of the present invention includes the following steps:

[0062] S31. When the voice data channel is enabled, the terminal sends an instruction to collect the noise signal to the Bluetooth headset;

[0063] Specifically, the voice data channel includes but is not limited to, for example, a music playback channel and a call channel. After the terminal establishes a connection with the Bluetooth headset, when the voice data channel is enabled, the terminal sends an instruction to collect noise signals to the Bluetooth headset through the Bluetooth protocol stack. Command The bluetooth headset picks up the noise.

[0064] S32, the Bluetooth headset collects the noise signal and sends it to the terminal;

[0065] Specifically, after receiving the instruction, the Bluetooth headset starts to detect low-frequency noise (100-1000 Hz) in the environment audible to...

Abstract

The invention discloses a Bluetooth headset noise reduction method, device and system and belongs to the technical field of electronic equipment. The method includes the steps that 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 and sends the noise signals to the terminal; the terminal generates inversion signals according to the noise signals and sends the inversion signals to the Bluetooth headset; the inversion signals are played by the Bluetooth headset along with music signals or voice signals. According to the Bluetooth headset noise reduction method, device and system, noise reduction of the Bluetooth headset is achieved on the terminal side through software, so that the Bluetooth headset is low in cost, small in size and convenient to carry.

Description

technical field [0001] The present invention relates to the technical field of terminals, and in particular, to a method, device and system for realizing noise reduction of a Bluetooth headset. Background technique [0002] With the increasing popularity of terminals, especially mobile terminals and Bluetooth functions, the technology has become more and more mature, and the application of Bluetooth headsets has become increasingly widespread. At present, there are two methods of noise reduction for Bluetooth headsets: active noise reduction and passive noise reduction. The active noise reduction function is to generate reverse sound waves equal to the external noise through the noise reduction system, neutralize the noise, and achieve the effect of noise reduction. Active noise-cancelling headphones have a noise-cancelling circuit that competes with external noise. Most of them use a larger head-mounted design, which can block external noise with structures such as earplug...
