Embodiment Construction

[0038] Such as figure 1 As shown, a preferred embodiment of the present invention proposes a volume control method, including:

[0039] Step S101, collecting the external environment sound signal of the car player, and simultaneously extracting the audio sound signal from the output signal of the car player;

[0040] The ambient sound signal outside the car player includes the audio sound signal emitted by the car player itself and the external environmental noise signal. This embodiment extracts the environmental noise signal from the environmental sound signal based on the principle of destructive interference or destructive interference, and then based on the environmental noise The signal adjusts the volume of the car player adaptively.

[0041] In order to extract the environmental noise signal from the environmental sound signal, this embodiment first collects the external environmental sound signal of the car player, and extracts the audio sound signal from the output ...

Abstract

The invention discloses a volume control method of an automobile player and the automobile player. The method comprises the following steps of: acquiring an external environment sound signal of the automobile player, and extracting a loudspeaker sound signal from an automobile player output signal; reversely processing the loudspeaker sound signal; superposing the loudspeaker sound signal which is reversely processed with the environment sound signal, and thus obtaining an environment noise signal; and according to the environment noise signal which is obtained and a preset gear value, regulating the volume of the automobile player. By the invention, self-adaptive control over the volume of the automobile player according to different external environment noises is realized, and an experience effect of a user is improved.

Description

technical field [0001] The invention relates to the technical field of audio and video playback such as car players, in particular to a car player and a volume control method. Background technique [0002] At present, cars have audio and video playback functions, but the volume adjustment method of existing car players does not have the function of volume adaptive control according to the different external environmental noises. When the volume is too low, the listeners or viewers will feel that the volume is too low, which will cause discomfort to the listeners or viewers. Contents of the invention [0003] The main purpose of the present invention is to provide a car player and volume control method that can be adaptively adjusted according to the volume of the external environment. [0004] In order to achieve the above object, the present invention proposes a volume control method, comprising: [0005] Collecting the external environment sound signal of the car playe...
