[0038] In step 102, the light effect system is controlled according to the multimedia audio, and the user audio and the multimedia audio are output through the sound effect system.

[0039] In this step, after obtaining the user audio and the multimedia audio, the car machine controls the light effect system according to the multimedia audio, and outputs the user audio and the multimedia audio through the sound effect system. In an embodiment, the vehicle comprises a light effect system, which can realize different light effects according to the multimedia audio, and comprises a sound effect system, which can play the user audio and the multimedia audio.

[0040] Exemplarily, the light effect system comprises a light effect system in the vehicle and a light effect system in the audio acquisition device, the audio acquisition device is a vehicle microphone, the multimedia audio is a song accompaniment, and the user audio is a human voice; when the user sings KTV in the vehicle, the light effect system in the vehicle and the light effect system in the audio acquisition device change in color and brightness according to the song accompaniment, and the sound effect system outputs the human voice and the song accompaniment after fusion, so that the sound and the light effect jointly construct a stronger KTV atmosphere, realize the linkage of vision and hearing, and improve the experience of the user singing KTV in the vehicle.

[0074] Referring to FIG. 6, another embodiment of the vehicle sound and light effect control method is provided, and the light effect system in the audio acquisition device is controlled according to the multimedia audio, including:

[0075] In step 301, the multimedia audio is processed to obtain audio features; the audio features represent the level changes of the multimedia audio.

[0076] In this step, the car machine in the vehicle processes the multimedia audio to obtain audio features after obtaining the multimedia audio; the audio features represent the level changes of the multimedia audio. In an embodiment, the car machine processes the multimedia audio by frame to obtain an audio frame set, for each audio frame in the audio frame set, the car machine calculates the average level value of each audio frame and maps the average level value to the range of 0-255 as the audio features.

[0077] In an embodiment, the processing of the multimedia audio to obtain the audio features includes:

[0078] In step 3011, the multimedia audio is filtered to obtain target audio.

[0079] In this step, the car machine in the vehicle filters the multimedia audio to obtain target audio; in an embodiment, the car machine performs low-pass filtering on the multimedia audio to filter out the audio above 500Hz in the multimedia audio and retain the audio below 500Hz in the multimedia audio to obtain the target audio.

[0080] In step 3012, the target audio is processed by frame based on a preset time length to obtain an audio frame.

[0081] In this step, the car machine in the vehicle processes the target audio by frame based on a preset time length to obtain an audio frame. For example, the preset time length is 50ms, and the car machine in the vehicle processes the target audio by frame every 50ms to obtain multiple audio frames.

[0082] In step 3013, the level information of each audio frame is processed to obtain the audio features corresponding to each audio frame.

[0083] In this step, the car machine in the vehicle processes the level information of each audio frame to obtain an average level value of each audio frame, and maps the average level value to the range of 0-255 as an audio feature. In an embodiment, for each audio frame, the car machine applies a window function (such as a Hamming window, a Hanning window, etc.) on each audio frame to reduce spectral leakage and reduce endpoint effects; for the data of each audio frame, the root mean square value thereof is calculated, that is, the square root of the average value of the sum of squares of each sample point. The specific formula is: wherein x i is the audio data of the i-th sample point, N is the number of samples of each audio frame, and RMS is the average level value. After the car machine determines the average level value of each audio frame, it determines the minimum level value and the maximum level value of the target audio, and maps the average level value to the range of 0-255 as an audio feature according to the average level value, the minimum level value and the maximum level value. The specific formula is: wherein DATA is the audio feature, RMS is the average level value, RMS min is the minimum level value. RMS max is the maximum level value.

[0084] Step 302, controlling the light effect system in the audio acquisition device according to the audio feature.

[0085] In this step, the car machine of the vehicle compares the audio features corresponding to adjacent two audio frames, and controls the light effect system in the audio acquisition device according to the comparison result.

[0086] In an embodiment, step 302 includes:

[0087] Step 3021, determining the level grade corresponding to each audio frame according to the audio feature.

[0088] In this step, the car machine of the vehicle determines the level grade corresponding to each audio frame according to the audio feature corresponding to each audio frame and a preset mapping relationship between the audio feature and the level grade. For example, the car machine of the vehicle obtains an average level value mapped to the range of 0-255 as the audio feature, divides 0-255 into 30 level grades, and assigns each 8 consecutive values in 0-255 to a level grade, and assigns 240-255 to the last level grade. The car machine of the vehicle determines which value in 0-255 the audio feature corresponds to according to the audio feature corresponding to each audio frame, and then determines the level grade corresponding to the audio frame according to which level grade the value of the audio feature falls into.

[0089] Step 3022, comparing the level grades corresponding to the audio frames to control the light effect system in the audio acquisition device.

[0090] In this step, the vehicle's car machine compares the level corresponding to the audio frame to control the light effect system in the audio acquisition device. In an embodiment, the audio frame is received by the car machine in the order of playing multimedia audio frame by frame, at this time, the car machine compares the level corresponding to the currently received audio frame with the level corresponding to the last received audio frame, and then controls the light effect system in the audio acquisition device according to the comparison result.

[0091] In an embodiment, step 3022 comprises:

[0092] Step 30221, if the level corresponding to the current audio frame is higher than the level corresponding to the reference audio frame, the light device in the light effect system is controlled to flash; the reference audio frame is the previous audio frame before the current audio frame;

[0093] In this step, the vehicle's car machine compares the level corresponding to the received current audio frame with the level corresponding to the reference audio frame, and if it is determined that the level corresponding to the current audio frame is higher than the level corresponding to the reference audio frame, the light device in the light effect system is controlled to flash; wherein the reference audio frame is the previous audio frame received by the vehicle's car machine before receiving the current audio frame.

[0094] In an embodiment, when the vehicle's car machine controls the light device in the light effect system to flash, the light parameter of the light device in the light effect system is also determined according to the audio feature corresponding to the current audio frame.

[0095] Step 30222, if the level corresponding to the current audio frame is lower than the level corresponding to the reference audio frame, the light parameter of the light device in the light effect system is determined according to the audio feature corresponding to the current audio frame.

[0096] In this step, the vehicle's car machine compares the level corresponding to the received current audio frame with the level corresponding to the reference audio frame, and if the level corresponding to the current audio frame is lower than the level corresponding to the reference audio frame, the light parameter of the light device in the light effect system is determined according to the audio feature corresponding to the current audio frame, and then the light color or light color intensity displayed by the light device in the light effect system is adjusted according to the light parameter.

[0097] Exemplarily, the car machine of the vehicle calculates the light parameter of the light device in the light effect system according to the audio feature corresponding to the current audio frame, and the light parameter is the RGB value of the color displayed by the light device; when the RGB value is (255, 128, 128), the car machine of the vehicle adjusts the light color displayed by the light device in the light effect system according to (255, 128, 128) to display a light color of light red; when the RGB value is (255, 0, 0), the car machine of the vehicle adjusts the light color displayed by the light device in the light effect system according to (255, 0, 0) to display a light color of red; when the RGB value is (139, 0, 0), the car machine of the vehicle adjusts the light color displayed by the light device in the light effect system according to (139, 0, 0) to display a light color of dark red.

[0098] In an embodiment, before the step of determining the level grade corresponding to each audio frame according to the audio feature, the method further comprises:

[0099] In step a1, if the audio feature is different from the reference audio feature, the step of determining the level grade corresponding to each audio frame according to the audio feature is executed; the reference audio feature is the audio feature corresponding to the previous audio frame before the current audio frame;

[0100] In step a2, if the audio feature is the same as the reference audio feature, the light effect system in the audio acquisition device is controlled according to the preset light effect control rule.

[0101] In steps a1 to a2, when the car machine of the vehicle receives the current audio frame, the audio feature corresponding to the current audio frame is compared with the reference audio feature corresponding to the reference audio frame first, the reference audio frame is the previous audio frame received by the car machine of the vehicle before the current audio frame, and the reference audio feature is the audio feature corresponding to the previous audio frame received by the car machine of the vehicle before the current audio frame. If the car machine of the vehicle determines that the audio feature corresponding to the current audio frame is different from the reference audio feature, it is determined that the multimedia audio is still playing, and the step of determining the level grade corresponding to each audio frame according to the audio feature is continued to be executed. If the car machine of the vehicle determines that the audio feature corresponding to the current audio frame is the same as the reference audio feature, it is determined that the multimedia audio has been played, and at this time, the light effect system in the audio acquisition device is controlled by the car machine of the vehicle according to the preset light effect control rule, wherein the preset light effect control rule is the color transformation rule of the light device in the light effect system in the audio acquisition device when there is no multimedia music playing.

[0102] The car machine of the embodiment processes the multimedia audio, and obtains the audio feature corresponding to each audio frame; according to the comparison result of the audio feature corresponding to the current audio frame and the audio feature corresponding to the previous audio frame, the light effect system in the audio acquisition device is controlled, so that the color and color intensity of the light device of the light effect system in the audio acquisition device can be transformed based on the multimedia audio, the interestingness and atmosphere of the user in the car K song are improved, and the experience of the user in the car K song is improved.

[0103] Referring to FIG. 7, another embodiment of the vehicle sound and light effect control method is proposed, and before the light effect system in the audio acquisition device is controlled according to the multimedia audio, the method comprises the following steps:

[0104] Step 401, when the multimedia audio issued by the central control system is not received, the light effect system in the audio acquisition device is controlled according to a preset light effect control rule;

[0105] In this step, when the car machine of the vehicle is powered on on the audio acquisition device, but the multimedia audio issued by the central control system is not received, the light effect system in the audio acquisition device is controlled according to a preset light effect control rule. In an embodiment, the preset light effect control rule is that the light device of the light effect system in the audio acquisition device is cyclically and breathingly transformed according to the order of red, yellow, blue, green and purple, one basic color is transformed every 10 seconds, the change interval between the basic colors is filled with a gradual color, each basic color lasts for 8 seconds, and the gradual color is completed within 2 seconds.

[0106] In an embodiment, the light effect system in the audio acquisition device is controlled according to the multimedia audio, comprising:

[0107] Step 402, if the multimedia audio issued by the central control system is received, the light effect system in the audio acquisition device is controlled based on the current light effect information of the light effect system and the multimedia audio.
