Problems solved by technology
For example, drivers often need to be able to hear navigation voices clearly; passengers sometimes need to listen to music or the radio, and the ambient noise when the vehicle is driving may interfere with passengers listening; in other cases, passengers need to talk or make a phone call without The sound you want to play is interfering
[0003] In the prior art, sound control can only be performed by increasing or decreasing the playback volume, and cannot automatically judge the needs of the driver or passengers, thereby automatically controlling the playback of the sound in the car

Embodiment Construction
[0028] Hereinafter, exemplary embodiments according to the present disclosure will be described in detail with reference to the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present disclosure, rather than all the embodiments of the present disclosure, and it should be understood that the present disclosure is not limited by the exemplary embodiments described here.
[0029] Application overview
[0030] As previously known, it is very common for drivers or passengers to use the audio in the car to play various sound source information during the ride in the vehicle. However, in different specific scenarios, drivers or passengers have different requirements for sound playback.
[0031] For example, the sound source information may specifically be music, radio and other audio for "entertainment" for passengers, and this type of sound source information may be collectively referred to as the first type of sound source inf...

Disclosed is a sound playing method and device in a car, comprising: determining a first sound playing parameter according to a passenger position; playing sound source information according to the first sound playing parameter; playing sound source information according to noise information in the car and the first sound playing parameter, determine the second sound playback parameter; play the sound source information according to the second sound playback parameter; determine the first sound playback parameter according to the passenger position, and adjust the first sound playback parameter according to the noise information in the car to determine the sound Play parameters, so that when the passenger's demand for sound playback changes, the playback effect of the sound source information is automatically changed to meet the different needs of passengers, so that each passenger can automatically obtain the ideal sound playback effect.
Description
technical field [0001] The present disclosure relates to the technical field of audio analysis, in particular to a method and device for playing sound in a car. Background technique [0002] During the ride in the vehicle, the driver or passengers may play various sounds through the stereo in the vehicle. Common sound playback includes playing music, playing navigation voice, or playing radio, etc. In different situations, drivers or passengers have different needs for sound playback. For example, drivers often need to be able to hear navigation voices clearly; passengers sometimes need to listen to music or the radio, and the ambient noise when the vehicle is driving may interfere with passengers listening; in other cases, passengers need to talk or make a phone call without The sound you want to play is interfering. [0003] In the prior art, sound control can only be performed by increasing or decreasing the playback volume, and cannot automatically judge the needs of ...
