[0050] With the increasing intelligence of cars, their functionality is becoming increasingly diverse. Traditional auditory experiences can be enhanced, and Dolby Atmos music can now be experienced in vehicles. Therefore, to help users more intuitively understand Dolby Atmos, this paper proposes a sound field simulation method, system, and vehicle based on the Unity3D engine.

[0051] Specifically, the sound field simulation method, system, and vehicle based on the Unity3D engine according to embodiments of the present invention are described below with reference to the accompanying drawings.

[0054] S110, set the sound source position;

[0055] Setting the audio source location includes:

[0056] Determine the location of all car audio systems in the vehicle;

[0057] Set corresponding circular ripple images at the positions of all car audio systems to indicate the location of the sound source.

[0059] Receiving a sound source signal based on the sound source location includes:

[0060] Based on the basic hardware functions of the vehicle, determine all the car audio systems that make sounds;

[0061] Acquire the sound emitted by at least one vehicle audio system as a sound source signal.

[0062] S130, sound field simulation based on sound source signal;

[0063] Among them, the sound field simulation based on the sound source signal includes:

[0064] Confirm whether the audio source signal exists;

[0065] If the sound source signal does not exist, wait for the next sound source signal;

[0066] If the sound source signal exists, the sound field simulation is performed based on the sound source position corresponding to the sound source signal through specific picture effects and the order of picture generation.

[0067] The sound field simulation method based on the Unity3D engine provided by the embodiment of the present invention effectively solves or improves to a certain extent the problem of realizing a vehicle-mounted Dolby Atmos simulation effect based on the Unity3D engine, and enables users to experience the Dolby Atmos sound field effect in a visual way.

[0068] In one embodiment of the present invention, performing sound field simulation based on the sound source position corresponding to the sound source signal by using specific image effects and the order of image generation includes:

[0069] The ripple image at the corresponding position of the car audio system that emits the sound is given an effect that gradually increases in size and then gradually appears and disappears, to represent the process of the car audio system at the corresponding position emitting the sound and then disappearing.

[0070] Generate a sound motion track with multiple track point locations. Each track point in the sound motion track generates an image with an outer edge blur effect and adjustable intervals. The image at each track point is gradually enlarged and then gradually appears and disappears, representing the propagation trajectory and volume changes of the sound emitted by the car audio system. The order in which the images of each track point are generated represents the propagation location of the sound.

[0071] Get the location of the car audio system in real time, continuously simulate the trajectory of the sound emitted by the car audio system propagating and diffusing in the vehicle until the diffusion trajectory gradually disappears, and wait for the next sound source signal.

[0072] In one embodiment of the present invention, generating a sound motion trajectory having a plurality of trajectory point positions includes:

[0073] A set of sound motion trajectories with multiple trajectory point positions is generated using a quadratic Bezier curve, with the position of the car audio as the starting point and the position of the car audio farthest from the starting point as the end point.

[0074] Figure 2 is a flowchart of a sound field simulation method based on the Unity3D engine, according to a specific embodiment of the present invention. Specifically, referring to Figure 2, first, the sound source location is set and the corresponding vehicle model is loaded into the Unity3D engine. New energy vehicles are equipped with multiple onboard speakers. The locations of all speakers are obtained from the vehicle's design drawings. A corresponding circular ripple image is placed at each obtained speaker location to represent the sound source location, achieving a sound diffusion-like effect. Next, a sound source signal is received based on the sound source location. In this embodiment, the sound source is determined based on the functionality provided by the vehicle's underlying hardware, and the sound from at least one speaker is obtained as the sound source signal. Finally, sound field simulation is performed based on the sound source signal. The presence of the sound source signal is confirmed. If not, the next sound source signal is waited for. If present, sound field simulation is performed based on the corresponding sound source location using specific image effects and the order in which the images are generated. The sound field simulation is performed based on the sound source location corresponding to the sound source signal using specific image effects and the order in which the images are generated. Specifically, for each speaker emitting sound, a ripple image corresponding to the speaker's location is given a gradual increase in size and then gradually fades in and out, representing the process from the speaker's emitting sound to its disappearance. Simultaneously, a set of motion trajectories is generated using a quadratic Bezier curve, starting with the speaker's location and ending at the location of the speaker farthest from the starting point. At each trajectory point, an image with a blurred edge effect is generated. The interval between generated images can be adjusted. Each image at each trajectory point also gradually increases in size and then gradually fades in and out, representing the sound propagation trajectory and volume changes. The order in which the images are generated represents the sound propagation location. By acquiring the location of the emitting speaker in real time, the propagation and diffusion trajectory of the sound emitted by the car audio system within the vehicle is continuously simulated until the diffusion trajectory gradually disappears, waiting for the next sound source signal. Of course, those skilled in the art will appreciate that other image generation effects can also be used to represent the visual effects of the sound track, which are also within the scope of protection of this invention.
