Embodiment 1

[0054] figure 1 It is a schematic diagram of the circuit of the earphone of the embodiment of the present invention, as figure 1 shown.

[0055] An embodiment of the present invention provides an earphone, including: a collector 10 , an audio analyzer 20 , a controller 30 and a noise reduction processor 40 . Wherein, the collector 10 is used for collecting environmental audio signals. The audio analyzer 20 is connected with the collector 10, and is used for analyzing the environmental audio signal to determine noise attributes and identify whether the environmental audio signal contains pre-stored keywords. The controller 30 is connected with the audio analyzer 20, and is used for outputting a corresponding control signal according to the recognition result of the noise attribute and whether it contains a pre-stored keyword. The noise reduction processor 40 is connected with the audio analyzer 20 and the controller 30 respectively, and is used to select one or more target n...

Embodiment 2

[0093] figure 2 It is a schematic diagram of a noise reduction method provided by an embodiment of the present invention. Such as figure 2 shown, including:

[0094] Step S101: acquiring an ambient audio signal;

[0095] Step S102: analyzing the environmental audio signal to determine the noise attribute to which the environmental audio signal belongs;

[0096] Step S103: performing speech recognition on the environmental audio signal to identify whether the environmental audio signal contains pre-stored keywords;

[0097] Step S104: According to the noise attribute and the speech recognition result, select a target noise reduction processing mode from multiple noise reduction processing modes, so as to use the target noise reduction processing mode to perform noise reduction processing on the environmental audio signal.

[0098] In the above step S101, the ambient audio signal may be collected by a collector, wherein the collector may be an ambient sound microphone inst...

Abstract

The embodiment of the invention discloses an earphone and a noise reduction method, wherein the earphone comprises a collector, an audio analyzer, a controller and a noise reduction processor, whereinthe collector is used for collecting environment audio signals; the audio analyzer is connected with the collector and is used for analyzing the environment audio signals to determine noise attributes and identifying whether the environment audio signals contain pre-stored keywords; the controller is connected with the audio analyzer and is used for outputting a corresponding control signal according to the noise attributes and an identification result whether the pre-stored keywords are contained; and the noise reduction processor is respectively connected with the audio analyzer and the controller and is used for selecting one target noise reduction processing mode from a plurality of noise reduction processing modes according to the control signals and adopting the target noise reduction mode to carry out noise reduction processing on the environmental audio signals. According to the technical scheme provided by the embodiment of the invention, different noise reduction processingmodes can be adopted for processing different environmental noise, and the noise reduction effect is improved.

Description

technical field [0001] The invention belongs to the technical field of wearable devices, and in particular relates to an earphone and a noise reduction method. Background technique [0002] At present, earphones have become an indispensable accessory when people use smart terminals. When watching videos or listening to music, they can obtain sound through earphones. With the continuous development of technology, there are more and more types of earphones. In addition to ordinary earphones, there are also noise-canceling earphones. Noise-cancelling headphones can accurately block noise, automatically adjust with changes in sound, and can perform real-time audio calibration to optimize sound output. [0003] However, the currently used noise reduction earphones have a relatively single function, which is only single-channel noise reduction. For different environmental noises, the noise reduction effect is not good, and there are limitations in functions. Contents of the inv...
