Problems solved by technology

It has been found in practice that when a legitimate user uses a microphone device, the microphone and the speaker of the microphone device usually start working at the same time. When the legitimate user only pays attention to the sound output by the speaker of the microphone device, Inputting sound through the microphone of the microphone device will aggravate the howling of the speaker of the microphone device, resulting in poor sound quality output by the microphone device

Embodiment 1

[0070] see figure 1 , figure 1 It is a schematic flowchart of a microphone device anti-interference method disclosed in an embodiment of the present invention. Among them, such as figure 1 As shown, the microphone device anti-jamming method may include the following steps:

[0071] 101. The microphone device acquires the target audio signal received by the microphone.

[0072] In the embodiment of the present invention, the microphone device is provided with a microphone and a speaker, wherein the microphone is an energy converter for converting sound signals into electrical signals, and the speaker is a transducer for converting electrical signals into acoustic signals. The microphone device can also be provided with a communication module, which can perform wired communication or wireless communication with the terminal device through the communication module, wherein the terminal device can be a smart phone (such as an Android phone, an iOS phone, etc.), a tablet compute...

Embodiment 2

[0083] see figure 2 , figure 2 It is a schematic flow chart of another anti-interference method for a microphone device disclosed in an embodiment of the present invention. Among them, such as figure 2 As shown, the microphone device anti-jamming method may include the following steps:

[0084] 201. The microphone device acquires the target audio signal received by the microphone.

[0085] 202. The microphone device performs filtering and noise reduction processing on the target audio signal to obtain a first processed audio signal.

[0086] 203. The microphone device performs audio amplification processing on the first processed audio signal to obtain a second processed audio signal.

[0087] In the embodiment of the present invention, in the actual application environment, the target audio signal received by the microphone will be interfered by environmental noise to varying degrees, and it is necessary to preprocess the target audio signal so that the processed secon...

Embodiment 3

[0119] see image 3 , image 3 It is a schematic flow chart of another anti-interference method for a microphone device disclosed in an embodiment of the present invention. Among them, such as image 3 As shown, the microphone device anti-jamming method may include the following steps:

[0120] 301. The microphone device acquires the target audio signal received by the microphone.

[0121] 302. The microphone device extracts target voiceprint features of the target audio signal.

[0122] As an optional implementation manner, the microphone device extracting the target voiceprint feature of the target audio signal may include the following steps:

[0123] The microphone device performs filtering and noise reduction processing on the target audio signal to obtain a first processed audio signal.

[0124] The microphone device performs audio amplification processing on the first processed audio signal to obtain a second processed audio signal.

[0125] The microphone device ...

Abstract

The invention relates to the electronic equipment technical field, and specifically relates to a microphone equipment anti-interference method and microphone equipment; the method comprises the following steps: the microphone equipment obtains a target audio signal received by a microphone on the microphone equipment; the microphone equipment extracts the target voiceprint characteristics of the target audio signal; the microphone equipment determines whether the extracted target voiceprint characteristics are matched with preset valid user voiceprint characteristics or not; if not, the microphone equipment lowers the microphone current reception sensitivity absolute value to be smaller than or equal to a preset threshold, thus preventing the loudspeaker from forming squealing. The methodcan prevent the microphone equipment loudspeaker from forming squealing when a non-valid user uses the microphone, thus improving the microphone equipment output sound quality.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, and in particular to an anti-interference method for microphone equipment and the microphone equipment. Background technique [0002] At present, electronic devices such as mobile phones and tablet computers are equipped with microphone devices, and people can realize functions such as sound input and sound output through the microphone devices. It has been found in practice that when a legitimate user uses a microphone device, the microphone and the speaker of the microphone device usually start working at the same time. When the legitimate user only pays attention to the sound output by the speaker of the microphone device, Inputting sound through the microphone of the microphone device will aggravate the howling of the speaker of the microphone device, resulting in poor sound quality output by the microphone device. Contents of the invention [0003] The embodiment of the prese...
