[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0014] In one embodiment, if Figure 1 As shown, a method for adjusting vehicle sound effects is provided, comprising the following steps S10 and S20: S10, receiving a sound effect mode signal collected in real time by an information collection module of the vehicle, and determining a sound effect mode according to the sound effect mode signal.

[0015] Understandably, the information acquisition module may be a pressure sensor, a position sensor, a distance sensor and / or an image sensor, etc., for real-time acquisition of relevant information of the vehicle, including a sound effect mode signal. Among them, the sound effect mode signal refers to a signal for controlling the sound effect mode of the vehicle audio. The collected sound effect mode signal is analyzed and processed to identify and confirm the sound effect mode currently used by the vehicle. The sound effect mode refers to the way in which sound is propagated when playing music. The sound effect mode includes but is not limited to the main driving mode, the co-pilot mode, the full vehicle mode and the panoramic sound mode. Among them, in the main driving mode, it is necessary to provide the best listening effect for the main driver. In the co-pilot mode, it is necessary to provide the best listening effect for the co-pilot. In the full vehicle mode, it is necessary to provide the best listening effect for all passengers in the car. In the panoramic sound mode, it is necessary to provide the best panoramic auditory experience for all passengers in the car.

[0016] S20. Determine a speaker position adjustment strategy according to the sound effect mode, so as to adjust the orientation angle and height position of the speaker installed on the vehicle according to the position adjustment strategy.

[0017] Understandably, after determining the sound effect mode, the adjustment strategy of the speaker position is further determined according to the sound effect mode. The speaker position adjustment strategy refers to the strategy for adjusting the position and orientation of the speaker. According to the speaker position adjustment strategy, the orientation angle and height position of the speaker installed on the vehicle are adjusted. For example, in the main driving mode, since it is necessary to provide the best listening effect for the main driver, it is necessary to adjust the orientation angle of the speaker to the main driver, and adjust the height position of the speaker to align with the head position of the main driver, so as to make the main driver's listening effect the best. In the co-pilot mode, since it is necessary to provide the best listening effect for the co-pilot. Therefore, it is necessary to adjust the orientation angle of the speaker to the co-pilot, and adjust the height position of the speaker to align with the head position of the co-pilot to ensure the auditory experience of the co-pilot in the co-pilot seat. Further, in the full vehicle mode, since it is necessary to provide the best listening effect for all passengers in the car, it is necessary to adjust the orientation angle of the speaker to the center position of the vehicle, and adjust the height position of the speaker to align with the head position of the target person to ensure that all passengers in the car get the best listening effect. In the panoramic sound mode, since it is necessary to provide the best panoramic auditory experience for all passengers in the car, the direction angle of the speaker needs to be adjusted to the center of the vehicle, and the height of the speaker needs to be adjusted to be higher than the preset height of the target person's head to ensure that all passengers in the car have the best panoramic auditory experience.

[0018] In this embodiment, the sound effect mode signal collected in real time by the information collection module of the vehicle is received, and the sound effect mode is determined according to the sound effect mode signal; then, the speaker position adjustment strategy is determined according to the sound effect mode, so as to adjust the orientation angle and height position of the speaker installed on the vehicle according to the position adjustment strategy. Here, the speaker position adjustment strategy is determined according to the current sound effect mode of the vehicle, and the orientation angle and height position of the speaker are adjusted according to the speaker position adjustment strategy, so that the members at the position corresponding to the sound effect mode have the best listening effect. In this way, by setting different sound effect modes, the most comfortable and immersive listening experience can be provided for passengers at different positions in the vehicle under different sound effect modes.

In this way, it is ensured that the main driver in the main driving seat can obtain the best sound experience, such as clearer intercom sound, more accurate navigation instructions or more immersive music experience.

[0022] In this embodiment, when the vehicle sound system is in the main driving mode, the angle and height of the speaker can be adjusted according to the position information of the main driver to ensure the optimization and personalization of the sound effect.

It should be understood that the full vehicle mode tends to ensure that the sound can be directly transmitted to the ears of all passengers in the vehicle, reducing the reflection and interference of the sound on other surfaces inside the vehicle; and the panoramic sound mode needs to ensure that the sound can be directly transmitted to the ears of all passengers in the vehicle, and also needs to ensure that the sound is evenly distributed in the car. Therefore, it is necessary to place the speaker in a higher position so that the sound transmitted to the ears of all passengers is more uniform. When the sound effect mode is set to the panoramic sound mode, the sound effect mode focuses on the panoramic auditory experience of the entire vehicle. At this time, the optimal orientation angle (fourth orientation angle) and the optimal height position (fourth position height) of the speaker are determined according to the vehicle full vehicle information to ensure the panoramic auditory experience of all passengers in the vehicle.

[0051] S2072. Determine a fourth position height that is higher than the preset height of the target person's head according to the fourth head height position; understandably, since the panoramic sound mode not only needs to ensure that the sound can be directly transmitted to the ears of all passengers in the vehicle, but also needs to ensure that the sound is evenly distributed in the vehicle, the panoramic sound mode needs to place the speaker at a higher position relative to the full vehicle mode, so that the sound transmitted to the ears of all passengers is more uniform. Here, the preset height refers to a pre-set height. For example, the preset height can be set according to demand, such as being set to 20 cm, that is, the fourth position height refers to a height 20 cm higher than the target person's head.

[0052] S2073. Determine the fourth pitch angle and the fourth rotation angle according to the center position coordinates, the speaker coordinates of the speaker, and the fourth position height.

Among them, the horizontal coordinates of the speaker are fixed and unchanged, and only the vertical (height direction) coordinates are adjustable. Here, the vertical coordinates of the speaker after adjustment can be determined according to the vertical coordinates before the speaker is adjusted and the fourth position height. The fourth pitch angle of the speaker can be calculated according to the center position coordinates and the vertical coordinates after the speaker is adjusted. The fourth rotation angle of the speaker can be calculated according to the center position coordinates and the horizontal coordinates of the speaker adjustment. After determining the fourth pitch angle and the fourth rotation angle, the speaker can be adjusted to the corresponding angle. For example, the fourth pitch angle can be adjusted at the same time during the height adjustment process by setting the rod (for example, setting the rod as a sliding rod with a certain inclination angle). After the speaker reaches the fourth position height, the fourth rotation angle can be adjusted in the horizontal direction. In this way, it can be ensured that the sound can be directly transmitted to the ears of all passengers in the vehicle, reducing the reflection and interference of the sound on other surfaces inside the vehicle.
