Problems solved by technology
In the above background, the adjustment of the car audio system has the following problems: on the one hand, due to the unprofessional nature of the occupants, the adjustment standard is only the operator's own sense of hearing, so the adjustment process is often blind and inaccurate. And it cannot meet the auditory needs of other passengers in the compartment; selection, which in turn leads to variability in the distribution of human ears in the car, and only by manually adjusting the volume, loudness, high-middle and low-pitch parameters of the car audio system cannot guarantee the auditory experience of every occupant in the car

The invention discloses a method and system for automatically adjusting the distribution of the sound field in a car. The method includes: preset the corresponding relationship between the distribution of human ears in the car and the sound field distribution scheme, obtain the first sensing signal, and obtain the second sensing signal , according to the first sensing signal and the second sensing signal to estimate the distribution of human ears in the car, further determine the sound field distribution plan in the car, and control the sound generation of the speaker system in the car according to the sound field distribution plan. The system includes: a control unit, a loudspeaker system, a first sensor and a second sensor, the first sensor and the second sensor respectively output a first sensing signal and a second sensing signal to the control unit, and the control unit and the second sensing signal to estimate the distribution of human ears in the car, further determine the sound field distribution plan in the car, and control the sound generation of the speaker system according to the sound field distribution plan. The invention optimizes and adjusts the distribution of the sound field facing the distribution of human ears in the vehicle, and can greatly improve the auditory experience of each occupant in the vehicle.
Description
technical field [0001] The invention relates to the field of automobiles, in particular to a method and system for automatically adjusting the distribution of the sound field in a vehicle. Background technique [0002] Car audio system is one of the most common entertainment systems in cars. With the improvement of quality of life, people's requirements for auditory experience are gradually increasing, and the utilization rate of car audio system is increasing day by day. In the current automobile market, the adjustment method of the car audio system is often realized through the manual operation of the occupant, and its controllable parameters generally include: music category, bass, midrange, treble, loudness and volume, etc. In the above background, the adjustment of the car audio system has the following problems: on the one hand, due to the unprofessional nature of the occupants, the adjustment standard is only the operator's own sense of hearing, so the adjustment proc...
