[0037] Figure 3 A hardware configuration block diagram of an audio device 300 according to an exemplary embodiment is shown. Figure 3The display device 300 shown includes at least one of the following: a communicator 301, an external device interface 302, a controller 303, a speaker 304, a driver assembly 305, and a power supply 306.

[0038] In one possible implementation, the controller 303 receives audio data input from the communicator 301 or an external device interface, and controls the drive component 305 to rotate according to the audio data, so that the drive component 305 adjusts the orientation of the left and right rotating speakers. It also adjusts the delay time of the audio data, the equalizer parameters of each channel, the gain of the audio data of each channel, and the mixing, and inputs the processed audio data into the corresponding speakers so that each speaker plays the corresponding sound.

[0039] Figure 4 A schematic diagram of the structure of an audio device 300 according to an exemplary embodiment is shown. Figure 4 As shown, the audio device 300 includes: a device body 307, a housing 308, a sound-emitting unit installed inside the housing 308, the sound-emitting unit being the aforementioned speaker 304; a drive assembly 305, one end of which is connected to the device body 307 and the other end of which is connected to the housing 308, for driving the housing 308 to rotate relative to the device body 307; and an audio input port 309 for receiving audio data sent by an audio output device.

[0040] The controller 303 can be a processor, circuit board, control board, etc. The drive assembly 305 can be composed of components such as a motor, gears, and connecting parts. The drive assembly drives the housing to rotate relative to the main body of the equipment. It can receive signals from the controller, and the controller signals cause the motor to rotate, which in turn drives the gears and other components to rotate, thereby causing the housing to rotate. The main body of the equipment 307 can be a cavity enclosed by any material, and a horn can also be installed in the main body of the equipment 307.

[0041] Continue to refer to Figure 4The controller 303 can be installed in the main body 307 or in the housing 308. The speaker 304 can be installed in both the main body 307 and the housing 308. There can be two housings; with the speaker facing forward, the one on the left is the left housing, and the one on the right is the right housing. The speaker installed in the left housing is a left-side rotating speaker, and the speaker installed in the right housing is a right-side rotating speaker. The speaker installed in the main body 307 can be a left main channel speaker, a right main channel speaker, a center main channel speaker, a subwoofer, etc. The audio input port 309 can include the aforementioned communicator 301 and external device interface 302. The audio input port 309 can be installed on the main body 307 or in the housing 308.

[0042] The controller is configured to perform steps S201 to S205.

[0043] S201: In response to receiving an angle adjustment command, read the equalizer parameters of each channel, and obtain the audio data input from the audio input port and the real-time orientation angle of the housing, wherein the audio data includes lateral audio.

[0044] In this step, the angle adjustment command can be sent by the user through a terminal device. The angle adjustment command can be a preset string. The equalizer parameters for each channel can be stored in the controller's memory. The audio data input to the audio input port can include audio data for each channel. The real-time orientation angle of the housing can be the target angle when the housing angle was last adjusted, or it can be the angle stored after the last housing angle adjustment. The real-time orientation angle can also be the difference between the current angle of the drive component and the preset angle.

[0045] Terminal devices include, for example, remote controls, mobile phones, computers, and tablets. The memory can be the aforementioned random access memory or read-only memory. Lateral audio can include left channel audio, right channel audio, left surround audio, right surround audio, left sky audio, and right sky audio.

[0046] S202: Calculate the standard value of lateral audio.

[0047] In this step, the standard values ​​for calculating the lateral audio can be the mean amplitude, median amplitude, mode amplitude, etc.

[0048] For example, calculate the average amplitude of the entire lateral audio segment, or calculate the average amplitude of the lateral audio over a preset time period.

[0049] The preset time can be set in advance, such as 1 minute, 5 minutes, 10 minutes, etc. The side audio can be audio from the side channels, such as left surround audio, left sky audio, right surround audio, etc.

[0050] S203: Calculate the target angle of the housing based on the standard value and the equalizer parameters of each channel.

[0051] In this step, you can either input the standard value and the equalizer parameters for each channel into a preset formula to obtain the target angle, or you can convert the equalizer parameters for each channel into corresponding amplitudes, and then input the amplitudes corresponding to the equalizer parameters and the standard value into a preset function to obtain the target angle.

[0052] S204: Determine the rotation angle based on the target angle and the real-time orientation angle.

[0053] In this step, the rotation angle can be obtained by subtracting the target angle from the real-time orientation angle.

[0054] For example, if the target angle is (30°, 10°) and the real-time orientation angle is (20°, 30°), then the rotation angle is (10°, -20°). As another example, if the target angle is (41°, 15°) and the real-time orientation angle is (45°, 20°), then the rotation angle is (-4°, -5°). This application does not limit the specific values ​​of the target angle, real-time orientation angle, and rotation angle.

[0055] In one possible implementation, the target angle includes the target vertical angle and the target horizontal angle, and the real-time orientation angle includes the real-time vertical angle and the real-time horizontal angle. The rotation angle includes the vertical rotation angle and the horizontal rotation angle.

[0056] The vertical and horizontal angles can be determined by the orientation of the housing and the sound-generating unit inside the housing.

[0057] The controller is configured to subtract the real-time vertical angle from the target vertical angle to obtain the vertical rotation angle.

[0058] For example, if the target vertical angle is 10° and the real-time vertical angle is 30°, then the vertical rotation angle is -20°. This application does not limit the specific numerical value of the angle.

[0059] The controller is also configured to subtract the real-time horizontal angle from the target horizontal angle to obtain the horizontal rotation angle.

[0060] For example, if the target horizontal angle is 10° and the real-time horizontal angle is 30°, then the horizontal rotation angle is -20°. This application does not limit the specific numerical value of the angle.

[0061] S205: Control the rotation of the drive component according to the rotation angle, so that the housing rotates to the target angle.

[0062] In this step, an electrical signal corresponding to the rotation angle can be sent to the drive component, causing the drive component to rotate by the corresponding angle. Since the drive component is connected to the housing, the housing will also rotate, thereby allowing the housing to reach the target angle.

[0063] For example, with a rotation angle of (10°, 15°), a corresponding electrical signal is sent to the drive assembly, causing the first motor of the drive assembly to rotate the number of revolutions corresponding to 10°, and the second motor of the drive assembly to rotate the number of revolutions corresponding to 15°, thereby causing the housing to rotate 10° vertically and 15° horizontally. This application does not limit the specific value of the rotation angle in its embodiments.

[0064] S206: Control the sound-emitting unit to emit the corresponding sound based on the lateral audio.

[0065] In this step, the lateral audio can be delayed, amplified, and then input into the sound-emitting unit inside the housing, causing the sound-emitting unit to emit the corresponding sound. Alternatively, the lateral audio can be mixed to obtain a mixed lateral audio, which is then input into the sound-emitting unit to make the sound-emitting unit emit the corresponding sound.

[0066] As can be seen from the description of the above embodiments, in this application embodiment, after receiving an angle adjustment command, the controller responds to the angle adjustment command, reads the equalizer parameters of each channel, obtains the audio data input from the audio input port and the real-time orientation angle of the housing, calculates the standard value of the lateral audio, calculates the target angle of the housing based on the standard value and the equalizer parameters, and determines the rotation angle based on the target angle and the real-time angle. Based on the value of the rotation angle, the controller controls the drive component to rotate, allowing the housing to rotate to the target angle, and controls the sound-emitting unit to emit sound based on the lateral audio. This realizes the control of the housing orientation based on different audio data, thereby improving the stereo surround effect of the music.

[0067] Continue to refer to Figure 4 In one possible implementation, the drive assembly 305 includes a left drive assembly 3051 and a right drive assembly 3052, and the housing 308 includes a left housing 3081 and a right housing 3082. One end of the left drive assembly is drivenly connected to the left housing, and the other end is drivenly connected to the device body, for driving the left housing to rotate relative to the device body. One end of the right drive assembly is drivenly connected to the right housing, and the other end is drivenly connected to the device body, for driving the right housing to rotate relative to the device body. Standard values ​​include left surround sound amplitude, left sky sound amplitude, right surround sound amplitude, and right sky sound amplitude. Equalizer parameters for each channel include: left sky equalizer parameters, left surround equalizer parameters, right sky equalizer parameters, and right surround equalizer parameters.

[0068] The connection method between the drive component and the housing and main body of the device is similar to that described in the above embodiments, and will not be repeated here. The distinction between the left and right housings can be based on the orientation of the speaker relative to the audio device. The standard values ​​correspond to the channels for side surround sound and side sky sound.

[0069] The controller, in the process of calculating the target angle in step S203 above, is configured to calculate the target angle of the left side shell based on the left surround sound amplitude, the left surround equalizer parameters, the left sky sound amplitude, the right sky sound amplitude, the left sky equalizer parameters, and the right sky equalizer parameters.

[0070] Specifically, the target vertical angle can be determined by combining surround sound parameters (left surround sound amplitude, left surround equalizer parameters) with all other parameters. The target horizontal angle can be determined by combining sky sound parameters (left sky sound amplitude, right sky sound amplitude, left sky equalizer parameters, and right sky equalizer parameters) with all other parameters.

[0071] The controller is also configured to calculate the target angle of the right side housing based on the right surround sound amplitude, right surround equalizer parameters, right sky sound amplitude, left sky sound amplitude, right sky equalizer parameters, and left sky equalizer parameters.

[0072] The target angle calculation method for the right side shell is similar to that for the left side shell, and can be achieved by swapping the left and right sides, so it will not be elaborated here.

[0073] As can be seen from the description of the above embodiments, the embodiments of this application calculate the target angle of the housing on one side by using the surround sound amplitude on one side, the surround sound equalizer parameters on this side, the sky sound amplitude on both sides, and the sky equalizer parameters on both sides. This enables the target angle of the housing on both sides to be adjusted separately for the different surround sounds on both sides, and the target angle is obtained from the sky sound and the surround sound, making the surround sound effect stronger.

[0074] In one possible implementation, the controller is configured to calculate the total amplitude of the left surround sound based on the left surround sound amplitude, the left surround equalizer parameters, and a preset formula for calculating the total amplitude of the left surround sound.

[0075] The formula for calculating the total amplitude of the left surround tone is as follows:

[0076] A 左环绕总 =A LS +f A (EQ LS )

[0077] In the formula, A 左环绕总 A represents the total amplitude of the left surround tone. LS Indicates the amplitude of the left surround tone, EQ LS This represents the left surround equalizer parameter, f. A This represents a preset conversion function. In this embodiment of the application, f... A The specific content is not limited, f A The specific content can be pre-set by the staff.

[0078] The controller is also configured to obtain the total amplitude of the left sky tone based on the amplitude of the left sky tone, the amplitude of the right sky tone, the parameters of the left sky equalizer, the parameters of the right sky equalizer, and a preset formula for calculating the total amplitude of the left sky tone.

[0079] The formula for calculating the total amplitude of the left sky tone is as follows:

[0080] A 左旋转总 =A LT +A RT +f A (EQ LT )+f A (EQ RT )

[0081] In the formula, A 左旋转总 A represents the total amplitude of the left sky tone. LT A represents the amplitude of the left sky tone. RT f represents the amplitude of the right sky tone. A This represents the preset transition function, EQ. LT This represents the parameters of the left sky equalizer, EQ. RT This indicates the parameters of the right sky equalizer.

[0082] The controller is also configured to calculate the target angle of the left side housing based on the total amplitude of the left surround sound and the total amplitude of the left sky sound.

[0083] Specifically, one could calculate the sum of the total amplitude of the left surround sound and the total amplitude of the left sky sound, and define this sum as the left amplitude sum. The horizontal angle of the left shell could be determined based on the proportion of the total amplitude of the left surround sound to the amplitude sum, and the vertical angle of the left shell could be determined based on the proportion of the total amplitude of the left sky sound to the amplitude sum.

[0084] The calculation method for the target angle of the right side shell is similar to that of the left side shell; simply interchange the left and right sides in the above formulas and parameters. It will not be elaborated here.

[0085] As can be seen from the description of the above embodiments, the embodiments of this application calculate the total surround sound amplitude on one side by inputting the surround sound amplitude on one side and the surround equalizer parameters on that side into a preset surround sound amplitude calculation formula. The total sky sound amplitude on this side is obtained by inputting the sky sound amplitude on one side, the sky sound amplitude on the other side, the sky equalizer parameters on this side, and the sky equalizer parameters on the other side into a preset total sky sound amplitude calculation formula. The target angle of the shell on this side is calculated from the total surround sound amplitude and the total sky sound amplitude on this side, thereby realizing the dynamic adjustment of the target angle by the total surround sound amplitude and the total sky sound amplitude, and increasing the surround sound effect of the audio.

[0086] In one possible implementation, the target angle includes the target vertical angle and the target horizontal angle.

[0087] The target vertical angle and target horizontal angle can be determined by the angle relative to the horn in the housing, or by the direction of the main body of the equipment.

[0088] Figure 5 A schematic diagram of horizontal and vertical angles provided for embodiments of this application. (See attached diagram.) Figure 5 As shown, the shell is a cube in the figure, and the horizontal angle is represented by θ in the figure. H Vertical angles are represented by θ. V express.

[0089] The controller is configured to add the total amplitude of the left surround sound and the total amplitude of the left sky sound to obtain the total amplitude.

[0090] Specifically, for example, if the total amplitude of the left surround sound is 10dB and the total amplitude of the left sky sound is 15dB, then the total amplitude is 25dB. For example, if the total amplitude of the left surround sound is 20dB and the total amplitude of the left sky sound is 3dB, then the total amplitude is 23dB. This application does not limit the specific values ​​of the total amplitude of the left surround sound, the total amplitude of the left sky sound, or the total amplitude in its embodiments.

[0091] The controller is also configured to calculate the target vertical angle based on the total amplitude, the total amplitude of the left sky sound, and a preset target vertical angle calculation formula.

[0092] The preset target vertical angle calculation formula can be pre-configured by the staff and can correspond to the specific model of the audio equipment.

[0093] In one possible implementation, the controller is further configured to calculate the target vertical angle based on the total amplitude, the total amplitude of the left sky sound, and a preset target vertical angle calculation formula, as follows:

[0094]

[0095] Where, θ V Let A represent the target vertical angle, 'a' represent a constant, and 'A' represent the vertical angle. 天空 A represents the total amplitude of the left sky tone. Mix Represents the total amplitude, θ′ V This indicates the preset vertical correction angle. The vertical correction angle can be obtained through prior testing or a pre-calibrated fixed value. The value of 'a' is, for example, -1 to 1, and can be adjusted according to different audio device models. The preset vertical correction angle range can be 0° to 90°, and can also be adjusted according to different audio device models.

[0096] The controller is also configured to obtain the target horizontal angle based on the total amplitude, the total amplitude of the left surround sound, and a preset target horizontal angle calculation formula.

[0097] In one possible implementation, the controller is further configured to calculate the target horizontal angle based on the total amplitude, the total amplitude of the left sky sound, and a preset target horizontal angle calculation formula, as follows:

[0098]

[0099] Where, θ H Let A represent the target horizontal angle, b represent a constant, and A represent the target horizontal angle. 环绕 A represents the total amplitude of the left surround tone. Mix Represents the total amplitude, θ′ H This indicates the preset horizontal correction angle. The horizontal correction angle can be obtained through prior testing or a pre-calibrated fixed value. The value of 'b' is, for example, -1 to 1, and can be adjusted according to different audio device models. The preset horizontal correction angle range can be 0° to 90°, and can also be adjusted according to different audio device models.

[0100] In one possible implementation, the method for calculating the target angle of the right side shell is similar to that in the embodiments of this application. It is only necessary to interchange the left and right sides in the formula and description, which will not be repeated here.

[0101] As can be seen from the description of the above embodiments, the embodiments of this application obtain the total amplitude by adding the total amplitude of the left surround sound and the total amplitude of the left sky sound, inputting the total amplitude and the total amplitude of the left sky sound into a preset target vertical angle calculation formula to obtain the target vertical angle, and inputting the total amplitude and the total amplitude of the left surround sound into a preset target horizontal angle calculation formula to obtain the target horizontal angle, thereby obtaining the target angle. This realizes the calculation of different vertical and horizontal angles based on the amplitude, thereby improving the stereo effect of the audio.

[0102] In one possible implementation, the preset target vertical angle calculation formula includes a preset vertical correction angle, and the preset target horizontal angle calculation formula includes a preset horizontal correction angle.

[0103] The vertical correction angle and the horizontal correction angle are as described in the above embodiments, and the sound-generating unit can be the above-described speaker.

[0104] The controller is also configured to, in response to receiving an environmental adaptation adjustment command, control the drive components to rotate to at least two preset angles, and control the sound unit to play preset test audio at each preset angle.

[0105] Specifically, the preset angle can be an angle corresponding to the preset angle of the housing, such as (0°, 45°) or (45°, 0°). 0° is to reduce sound generation in the vertical or horizontal direction, and 0° can also be replaced with other smaller angles.

[0106] The controller is also configured to receive analytical audio signals sent by the microphone corresponding to each preset angle, wherein the analytical audio signals are sent by the microphone after receiving spatial audio, and the spatial audio is obtained after the test audio has been propagated through the environment.

[0107] Specifically, the microphone can be pre-installed in the audio system, the remote control, or a mobile phone microphone used in conjunction with a related application. Spatial audio can be obtained by analyzing changes in audio after reflection from the environment. This analytical audio is obtained by the microphone performing signal preprocessing on the spatial audio. The preprocessing process can be executed by a program already present in the microphone; this embodiment does not impose specific limitations on the preprocessing process. Before receiving the analytical audio, a prompt message is played, which may be a message reminding the user to remain quiet. Since the analytical audio is obtained after the sound-emitting unit emits test audio, the analytical audio corresponds to the preset angle at which the test audio is emitted.

[0108] The controller is also configured to determine the vertical and horizontal correction angles based on the test audio and each analysis audio.

[0109] Specifically, the vertical and horizontal correction angles can be determined based on the frequency and energy differences between the test audio and each analysis audio.

[0110] In one possible implementation, the controller is configured to calculate the similarity between each analyzed audio and the test audio.

[0111] Specifically, the similarity of each audio sample can be obtained by inputting the analysis audio and test audio into a pre-configured similarity determination algorithm.

[0112] The similarity determination algorithm can be pre-configured by staff, and this application embodiment does not impose specific restrictions on it.

[0113] The controller is also configured to determine the preset angle corresponding to the target analysis audio as the target correction angle.

[0114] Specifically, the target analysis audio is obtained when the driving component rotates to a preset angle, and the target analysis audio corresponds to the preset angle.

[0115] The controller is configured to identify the audio with the highest similarity among the analyzed audios as the target audio for analysis.

[0116] For example, if the similarity of the three analyzed audios is 70%, 75%, and 95% respectively, then the analyzed audio with a similarity of 95% is identified as the target analyzed audio.

[0117] The controller is also configured to determine the vertical angle of the target correction angle as the vertical correction angle and the horizontal angle of the target correction angle as the horizontal correction angle.

[0118] Specifically, the target correction angle can be composed of vertical angles and horizontal angles. The vertical correction angle and the horizontal correction angle can be combined as an array or a string with a preset format to form the target correction angle.

[0119] As can be seen from the description of the above embodiments, the embodiments of this application control the drive component to rotate to at least two preset angles after receiving the welcome adaptation adjustment command, and control the sound unit to play preset test audio at each preset angle, receive the analysis audio sent by the microphone, and determine the vertical correction angle and the horizontal correction angle from the test audio and each analysis audio, so that the calculation of the vertical angle and the horizontal angle has a benchmark, and the surround effect of the audio playback is better.

[0120] Figure 6 This is a schematic flowchart of the correction angle acquisition method provided in an embodiment of this application. Figure 6 As shown, the method for obtaining the correction angle includes the following steps: S601: Controlling the drive component to rotate to a first preset angle, then playing a test signal and receiving a first analysis audio. S602: Controlling the drive component to rotate to a second preset angle, then playing a test signal and receiving a second analysis audio. S603: Controlling the drive component to rotate to a third preset angle, then playing a test signal and receiving a third analysis audio. S604: Calculating the horizontal correction angle from the second and first analysis audios, and calculating the vertical correction angle from the third and first analysis audios.

[0121] In one possible implementation, the preset angles include a first preset angle, a second preset angle, and a third preset angle.

[0122] The controller is configured to determine the analysis audio corresponding to a first preset angle as the first analysis audio, the analysis audio corresponding to a second preset angle as the second analysis audio, and the analysis audio corresponding to a third preset angle as the third analysis audio.

[0123] The first preset angle is, for example, (45°, 45°) or (45°, 30°), the second preset angle is, for example, (0°, 45°) or (-1°, 60°), and the third preset angle is, for example, (55°, -5°) or (45°, 0°). This application does not limit the specific values ​​of the preset angles, but the vertical angle of the second preset angle can be relatively small, for example, less than 10° or less than 20°, to reduce the influence of sky noise. The horizontal angle of the third preset angle can be relatively small, for example, less than 10° or less than 20°, to reduce the influence of surround sound.

[0124] The controller is also configured to divide the second analyzed audio by the first analyzed audio and multiply it by a first preset parameter to obtain a horizontal correction angle.

[0125] Specifically, the horizontal correction angle can be calculated using the following formula:

[0126]

[0127] In the formula, θ′ H S1 represents the horizontal correction angle, α represents a constant, S2 represents the second analysis audio, and S1 represents the first analysis audio.

[0128] The controller is also configured to divide the third analytical audio by the first analytical audio and multiply it by a second preset parameter to obtain a vertical correction angle. The analytical audio can be the amplitude or frequency of the analytical audio, or the energy of the analytical audio calculated from its amplitude and frequency.

[0129] Specifically, the vertical correction angle can be calculated using the following formula:

[0130]

[0131] In the formula, θ′ V S represents the vertical correction angle, β represents a constant, S3 represents the second analysis audio, and S1 represents the first analysis audio.

[0132] As can be seen from the description of the above embodiments, the embodiments of this application calculate the horizontal correction angle and the vertical correction angle by analyzing the audio from three different angles, thereby making the vertical and horizontal angles of the final target angle more accurate and thus enhancing the stereo effect of the audio.

[0133] Taking the vertical angle as an example, the empty box receiver first reads a certain length of audio data, and then calculates the A value of the sky tone component based on the previously introduced calculation. 环绕 The deviation is compared to the total amplitude, and the resulting deviation is weighted by a coefficient α, adjusting the model based on a fixed deflection angle. When equal to the reference amplitude, the fixed deflection angle is maintained; when greater than the reference amplitude, the angle is increased to reduce the direct sound component and enhance the reflected sound component. Designers can flexibly adjust α and β to achieve different adjustment effects. Considering the system's response time, this analysis and calculation are performed as preprocessing. That is, before the system emits sound and the angle is adjusted, data is pre-read for mixing, analysis, and angle calculation. After the angle is obtained, it is compared with the current model to determine and adjust the rotation angle. α and β can make the adjustment effect more pronounced or less pronounced.

[0134] Figure 7 This is a schematic diagram illustrating the process of obtaining and adjusting the correction angle as provided in an embodiment of this application. Figure 7 As shown, after receiving the audio signal, the microphone preprocesses the signal and inputs it into the audio device. The controller of the audio device performs frequency analysis and energy analysis, and generates calibration parameters (horizontal correction angle and vertical correction angle) based on pre-stored standard parameters. The signal input module can be the aforementioned communicator or the aforementioned external device interface. The controller may also include an audio decoding module, a sound effect post-processing module, a rotation control module, and a sound field rendering module. The audio decoding module decodes the input audio data, and the decoded audio data is input into the sound effect post-processing module. The sound effect post-processing module mixes the audio and inputs it into the sound field rendering module. The sound field rendering module inputs the audio from each channel into the corresponding channel's sound unit. The rotation control module controls the drive components to rotate the housing.

[0135] Figure 8 This is a schematic diagram illustrating the mixing method provided in an embodiment of this application. Figure 8 As shown, the audio device modulates the input audio using EQ, adjusts the delay time, and then mixes it. The left channel, right channel, bass, and center channel are not mixed. The left overhead channel, left surround channel, and right overhead channel are mixed and then sent to the sound unit in the left housing, while the right overhead channel, right surround channel, and left overhead channel are mixed and then sent to the sound unit in the right housing.

[0136] In one possible implementation, when performing step S206 above, the controller is also configured to acquire the delay values ​​for each channel.

[0137] The delay value can be pre-stored in the controller or pre-stored in the storage unit.

[0138] The controller is also configured to add the delay value of each channel to the delay time of each channel in the audio data to obtain the total delay time of each channel.

[0139] Specifically, for example, if the left surround channel delay is 50ms and the total delay time of the left surround channel is 5ms, then the total delay time of the left surround channel is 55ms. As another example, if the right sky channel delay is 20ms and the total delay time of the right sky channel is 3ms, then the total delay time of the right sky channel is 23ms. Yet another example, if the right surround channel delay is 33ms and the total delay time of the right surround channel is 8ms, then the total delay time of the right surround channel is 41ms.

[0140] The controller is also configured to mix the side audio based on the amplitude of each channel in the delayed audio data and the equalizer parameters of each channel to obtain the mixed side audio.

[0141] Specifically, the left surround amplitude, left surround equalizer parameters, and left surround channel audio in the delayed audio data can be multiplied to obtain the left surround value; the left sky amplitude, left sky equalizer parameters, and left sky channel audio in the delayed audio data can be multiplied to obtain the left sky value; the right sky amplitude, right sky equalizer parameters, and right sky channel audio in the delayed audio data can be multiplied to obtain the right sky value; and the left surround value, left sky value, and right sky value are added together to obtain the mixed left-side audio. The calculation method for the mixed right-side audio is similar to that for the mixed left-side audio, except that the above parameters are reversed, and will not be elaborated here.

[0142] The controller is also configured to input the mixed lateral audio into the sound unit so that the sound unit emits the corresponding sound.

[0143] Specifically, the right-side audio after mixing can be input into the sound unit in the right-side housing, causing the sound unit in the right-side housing to play the right-side audio after mixing, and the left-side audio after mixing can be input into the sound unit in the left-side housing, causing the sound unit in the left-side housing to play the left-side audio after mixing.

[0144] As can be seen from the description of the above embodiments, the embodiments of this application obtain the delay value of the audio device and add the delay value to the delay time in the audio to obtain the total delay time, thereby replacing the original delay time in the audio data to obtain delayed audio data. The amplitude of each channel and the equalizer parameters of each channel in the delayed audio data are used for mixing, and the side audio obtained after mixing is input into the corresponding side sound unit to play the mixed sound, making the sound more three-dimensional.

[0145] In one possible implementation, the controller is also configured to input audio data into a preset audio type analysis model to obtain the target type of the audio data.

[0146] The audio type analysis model can be pre-trained or can be a neural network model.

[0147] The controller is also configured to look up the correspondence between audio type and angle based on the target type to obtain the target angle.

[0148] The correspondence between audio type and angle can be predefined, and its storage format can be a table or key-value pairs, etc. This application embodiment does not impose specific restrictions on the storage method of the correspondence.

[0149] For example, if the target type is "movie," then the target angle has a vertical angle of 70° and a horizontal angle of 45°. If the target type is "music," then the target angle has a vertical angle of 60° and a horizontal angle of 35°. If the target type is "news," then the target angle has a vertical angle of 30° and a horizontal angle of -30°. If the target type is "sports," then the target angle has a vertical angle of 60° and a horizontal angle of 40°.

[0150] As can be seen from the description of the above embodiments, the embodiments of this application obtain the target type of the audio data by inputting the audio data into the audio type analysis model, thereby finding the target angle corresponding to the target type, and realizing the use of different angles for different types of audio data, thereby producing different environmental sound effects for different types of audio.
