An in-vehicle reconstruction method and device for an out-vehicle environment sound field

Abstract

The invention relates to an in-vehicle reconstruction method and device for an out-vehicle environment sound field. The method comprises the steps that an out-vehicle environment sound signal is acquired; And the acquired external environment sound signal is processed, so that the processed external environment sound signal can be played in the vehicle. The method and the device are characterizedin that a microphone is mounted on a vehicle body; After being processed, the vehicle external environment sound signal is played through the loudspeaker in the vehicle, so that a user can listen to the vehicle external environment sound when a vehicle window is closed in the driving process of the vehicle, the safety in the driving process is improved, and the situations that the working state ofan air conditioner is not good and energy is wasted when the user listens to the external sound after opening the window are avoided. Besides, the directional microphones are arranged in multiple directions, and the loudspeakers in the corresponding directions are arranged in the vehicle, so that the external environment sound signals played in the vehicle have the direction information of the external sound environment, the user can listen to the sound more truly, and the experience is more natural.

Description

technical field [0001] The invention relates to the technical field of audio processing, in particular to a method and a device for reconstructing an in-vehicle environmental sound field outside a vehicle. Background technique [0002] In the prior art, generally when the vehicle is running, the window is closed, and it is difficult to hear the sound outside the vehicle when the window is closed. On the one hand, it isolates the ambient noise outside the car. On the other hand, when the user needs to listen to the ambient sound outside the car, for example, when the user is driving for an outing, he hopes to listen to the natural sound of the suburbs, but it cannot be realized when the window is closed. need. If you open the window to listen to the sound outside the car, the air conditioner in the car will not be able to work at its best, resulting in energy waste. The open state of the window will bring a lot of inconvenience to the user, and will bring potential safety h...

[0002] In the prior art, generally when the vehicle is running, the window is closed, and it is difficult to hear the sound outside the vehicle when the window is closed

On the one hand, it isolates the ambient noise outside the car. On the other hand, when the user needs to listen to the ambient sound outside the car, for example, when the user is driving for an outing, he hopes to listen to the natural sound of the suburbs, but it cannot be realized when the window is closed. need

If you open the window to listen to the sound outside the car, the air conditioner in the car will not be able to work at its best, resulting in energy waste. The open state of the window will bring a lot of inconvenience to the user, and will bring potential safety hazards
