DETAILED DESCRIPTION

[0056] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the invention more thorough and comprehensive.

[0057] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time. The terms "parallel", "first", "second", "third" and similar expressions used herein are for illustrative purposes only.

[0058] Combination Figures 1 to 5 As shown, the sound-transmitting display device of the present invention is exemplarily shown, including a box body 1, a screen bracket 3, a PCB board 5, a speaker 4, a first translation drive mechanism 6 and a controller (not shown in the figure).

[0059] See also Figure 1 The box body 1 is a rectangular parallelepiped with a receiving cavity 13 inside. One end of the box body 1 is open, and the receiving cavity 13 is connected to the opening. The opening of the box body 1 is covered with a screen mask 31, and the screen mask 31 is provided with a plurality of through holes for sound to pass through. The screen mask 31 is installed on the screen bracket 3. On the one hand, the screen bracket 3 can provide stable support for the screen mask 31, effectively preventing the mask from being damaged due to accidental collision or falling, and playing a good protective role. On the other hand, the screen bracket 3 can be used to drive the screen mask 31 to translate, so as to change the size of the sound cavity space during the propagation of sound waves, so that the sound-transmitting display device can perform diversified processing on the sound.

[0060] The speaker 4 is disposed in the housing 13 of the box 1. The housing 13 between the speaker 4 and the screen mask 31 is provided with a PCB board 5. The side of the PCB board 5 facing the screen mask 31 is provided with a plurality of SMD lamp beads 51. Figure 4 , which shows a structural schematic diagram of a small PCB board 5, wherein the SMD lamp beads 51 on the PCB board 5 together form a plurality of lamp groups arranged in a matrix, and each lamp group is composed of four SMD lamp groups arranged in a matrix. For example, the lamp beads 51 on the PCB board 5 can be used to play film and television images, and when the sound cavity space formed between the screen mask 31 and the PCB board 5 changes, the lamp beads 51 on the PCB board 5 can adjust the parameters of the lamp beads 51 accordingly so that the display effect of the film and television image will not appear to be protruding or concave due to the change in the distance from the screen mask 31, affecting the reflection effect of the film and television works.

[0061] See also Figure 2 , Figure 3 , a plurality of first sound-transmitting through holes 52 are provided on the PCB board 5. Preferably, the first sound-transmitting through holes 52 are circular through holes and are provided in the middle area of ​​each lamp group. The first sound-transmitting through holes 52 are used to transmit the sound of the speaker 4 to the screen mask 31 through the first sound-transmitting through holes 52, thereby achieving the effect of screen sound-transmitting. Figure 2 As shown, a plurality of screen through holes are provided on the screen mask 31, and the screen through holes include a plurality of circular through holes and square through holes. The screen through holes are used for transmitting the sound of the speaker 4 to the outside of the sound-transmitting display device through the screen mask 31, so as to ensure that the sound can be transmitted more directly from the sound-transmitting port through the screen through holes. Preferably, the circular through holes in the screen through holes are equal in size to the first sound-transmitting through holes 52, and the plurality of screen through holes are coaxially arranged with the plurality of first sound-transmitting through holes 52 in a one-to-one correspondence, so as to facilitate the transmission of the sound.

[0062] See also Figure 2 , the first translation driving mechanism 6 is arranged on the box 1, and the first translation driving mechanism 6 is drivingly connected with the screen bracket 3. When the first translation driving mechanism 6 is working, it can drive the screen bracket 3 to approach or move away from the PCB board 5 to adjust the distance between the two, thereby changing the size of the sound cavity space formed between the box 1, the screen mask 31 and the PCB board 5; for sounds of different frequency bands, different cavity space sizes can be adjusted so that the reflection, resonance and other characteristics of the sound bring different effects, thereby better showing the characteristics of sounds of different frequency bands and achieving diversified processing of sounds.

[0063] The controller of the sound-transmitting display device can be a control module arranged on the box 1 and connected to the lamp beads 51 on the PCB board 5 and the first translation drive mechanism 6, or it can be an independent server or an additional module of the server arranged outside the sound-transmitting display device and communicatively connected to the lamp beads 51 on the PCB board 5 and the first translation drive mechanism 6. The controller can control the lamp beads 51 in real time to play the film and television images corresponding to the audio and video band and control the first translation drive mechanism 6 to adjust in real time to the position of presenting the corresponding audio and video band.

[0064] To summarize, a sound-transmitting display device provided in an embodiment of the present application adjusts different bracket heights through the screen bracket 3 and the first translation drive mechanism 6 to change the size of the sound cavity space between the sound waves transmitted through the air holes to the screen mask 31. Different sound propagation effects are displayed through different sound cavity spaces, thereby realizing diversified processing of sound and enriching the sound effect. At the same time, the controller automatically controls the first translation drive mechanism 6 in real time to drive the screen bracket 3 to realize automatic adjustment, thereby reducing the tediousness of manual adjustment of the screen bracket 3. In addition, the automatic adjustment can make the film and television effects more natural and facilitate the screening of film and television works.

[0065] In one embodiment, if Figure 2 As shown, the sound-transmitting display device further includes a PCB support plate 2, which is installed in the accommodating cavity 13 and divides the accommodating cavity 13 into a front cavity 131 and a rear cavity 132, wherein the rear cavity 132, the front cavity 131 and the opening are linearly distributed in sequence; wherein the front cavity 131 is located between the screen bracket 3 and the PCB support plate 2, the rear cavity 132 is located between the PCB support plate 2 and the back plate of the box 1, and the PCB board 5 is placed in the front cavity 131 of the box 1 and installed on the PCB support plate 2. Specifically, due to the circuit board material characteristics of the PCB board 5, it is relatively fragile, and the PCB support plate 2 can protect the PCB board 5 to prevent the frequent movement of the screen mask 31 from affecting the PCB board 5 and causing the PCB board 5 to be damaged. In order to ensure the continuity of the sound propagation path, a plurality of second sound-transmitting through holes 22 are opened on the PCB support plate 2, and the plurality of second sound-transmitting through holes 22 are coaxially arranged one by one with the plurality of first sound-transmitting through holes 52, so that the sound waves of the speaker 4 can pass through the second sound-transmitting through holes 22 and the first sound-transmitting through holes 52 in sequence and then be transmitted to the screen mask 31.

[0066] Preferably, in the process of the sound waves of the speaker 4 propagating from the rear cavity 132 to the front cavity 131, the two form an interrelated acoustic system. When the space of the front cavity 131 changes, it will directly affect the propagation characteristics of the sound in the front cavity 131, such as the resonance frequency, volume and timbre and other sound characteristics. Since the rear cavity 132 is closely connected to the front cavity 131, the changes in the front cavity 131 will be synchronously fed back to the rear cavity 132, changing the propagation effect of the sound in the rear cavity 132. Therefore, the diversity of sound adjustment is not only reflected in the changes in the space of the front cavity 131, but also starts from the rear cavity 132, and passes through the front cavity 131 to the screen mask 31 to achieve the final sound expression effect. When the space of the front cavity 131 changes, the reasonable use of the changes in the sound of the rear cavity 132 can make the sound achieve a better effect.

[0067] See also Figure 1 , Figure 3 , wherein a plurality of mounting through holes 21 are provided on the PCB support plate 2, and a plurality of corresponding avoidance holes 53 are provided on the PCB board 5, and the plurality of avoidance holes 53 are coaxially arranged with the plurality of mounting through holes 21 in a one-to-one correspondence; preferably, the mounting through hole 21 can be part of the second sound-permeable through hole 22, and the avoidance hole 53 can be part of the first air-permeable through hole corresponding to the mounting through hole 21.

[0068] like Figure 3 As shown, the first translation driving mechanism 6 is arranged in the rear cavity 132 of the box body 1, which includes a first motor 61, a synchronous driving wheel 62, a synchronous driving wheel 62, a synchronous belt 63, a plurality of synchronous driven wheels 64 and a plurality of rotary transmission rods 65; wherein the synchronous driving wheel 62 is connected to the first motor 61; the synchronous belt 63 is wound around the synchronous driving wheel 62; the plurality of synchronous driven wheels 64 are wound around the synchronous belt 63; the plurality of rotary transmission rods 65 are arranged at intervals and parallel to each other, and the plurality of rotary transmission rods 65 are respectively passed through one of the avoidance The holes 53 are respectively pivotally connected to one of the mounting holes 21, and are axially fixed relative to the corresponding mounting holes 21 (axial fixation means that although the rotary transmission rod 65 is rotatably connected to the mounting hole 21, the two cannot move relative to each other in the axial direction). The multiple rotary transmission rods 65 are linked and connected with the multiple synchronous driven wheels 64 in a one-to-one corresponding manner; the rotary transmission rod 65 is provided with a transmission threaded section 651, and the screen bracket 3 is provided with a plurality of sliders 32, each of which is slidably matched with one of the threaded sections 651. The first translation drive mechanism 6 has a simple structure and is easy to implement. Figure 5In the direction of movement indicated by the middle arrow, the sound-transparent display device drives the slider 32 to move through the rotation of the thread, thereby driving the screen bracket 3 to move synchronously as a whole. Since the transmission force at each location mainly comes from the cooperation between the thread segment 651 and the slider 32, the transmission force is relatively close, making the force transmission of the entire system more uniform during the movement. This can effectively avoid the movement speed difference caused by uneven force transmission, ensure that each part of the screen bracket 3 can move at a relatively consistent speed, improve the stability and reliability of the system, and make the operation smoother and more accurate.

[0069] Exemplarily, the first translation drive mechanism 6 can also be arranged in the front cavity 131 of the box body 1, but in this case, a separate fixing mechanism needs to be arranged for the rotary transmission rod 65, which increases the use of additional parts. The additional fixing mechanism may also cause certain obstacles to the display of the lamp beads 51 and have certain effects on the projection of film and television images, such as uneven brightness of the picture, shadows, or blocking of part of the image content. The PCB support plate 2, while playing the original role of supporting the PCB board 5, is also used to support the rotary transmission rod 65, achieving dual purposes of one thing, making full use of the existing structure, reducing the use of additional parts, reducing costs and space occupancy, and will not have adverse effects on the display of the lamp beads 51 and the projection of film and television images, thereby providing users with a better visual experience.

[0070] In one embodiment, if Figure 5 As shown, the rotary transmission rod 65 is a tubular structure, and the threaded section 651 penetrates the outer tube wall and the inner tube wall of the rotary transmission rod 65; when installing the slider 32, the hollow tube design can facilitate the installation and disassembly of the slider 32. Secondly, the penetrating threaded section 651 makes the tubular structure more visible, and the position and movement state of the slider 32 on the rotary transmission rod 65 can be intuitively observed, which is convenient for timely detection of problems and adjustments.

[0071] Preferably, the starting end of the thread segment 651 is located between the two ends of the rotary transmission rod 65, and the tail end of the thread segment 651 is located between the two ends of the rotary transmission rod 65; in this way, the thread segment 651 is arranged at the middle section of the rotary transmission rod 65. Since both ends of the thread segment 651 are arranged at the two ends of the rotary transmission rod 65, the movement of the slider 32 is also limited between the rotary transmission rod 65, thereby reducing the risk of the slider 32 falling off and making the transmission more stable. In order to prevent the transmission relationship between the thread segment 651 and the slider 32 from being destroyed, the starting end of the thread segment 651 and the tail end of the thread segment 651 are both provided with a buffer pad 652, which can be used to abut the slider 32 to avoid the rigid collision caused by the asynchronous movement from destroying the transmission relationship.

[0072] In one embodiment, the sound-transmitting display device provided by the present application further includes a second translation driving mechanism 7, such as Figure 1 , Figure 2 As shown, the second translation drive mechanism 7 is connected to the speaker 4; the controller of the sound-transmitting display device is connected to the second translation drive mechanism 7, which can control the second translation drive mechanism 7 to drive the speaker 4 to move closer to or away from the PCB board 5. Specifically, the second translation drive mechanism 7 can change the size of the space of the rear cavity 132 to adjust the sound, so that the propagation effect of the sound in the rear cavity 132 can not only be changed by the change of the space of the front cavity 131, but also by actively changing the size of the sound propagation space in the rear cavity 132, thereby increasing the processing method of the sound waves of the speaker 4 and further enriching the sound processing effect.

[0073] The speaker 4 includes a speaker support plate 41 and a plurality of speaker units 42. The speaker support plate 41 is parallel to the PCB board 5. The plurality of speaker units 42 are distributed on the speaker support plate 41 at intervals. The speaker support plate 41 allows the plurality of speaker units 42 to be distributed at intervals along the height direction. Moreover, since the speaker support plate 41 is parallel to the PCB, the speaker units 42 can be more evenly distributed toward the PCB board 5, and the sound transmission is more uniform.

[0074] In one embodiment, the box body 1 is provided with a plurality of guide rails 11, each guide rail 11 is movably matched with at least one guide block 12, the speaker support plate 41 is fixedly connected to the plurality of guide blocks 12, and the extension direction of the guide rail 11 is the direction in which the second translation drive mechanism 7 drives the speaker 4 to approach or move away from the PCB board 5.

[0075] In terms of transmission, the loudspeaker support plate 41 based on the large panel structure adopts multiple guide rails 11 to assist the drive, ensuring the directional accuracy during the transmission process, avoiding offset or misalignment, and thus ensuring the stability of the overall structure of the equipment. The cooperation of multiple guide rails 11 and guide blocks 12 can greatly disperse the friction generated when the loudspeaker support plate 41 moves, making the movement smoother, reducing energy loss, and improving the operating efficiency of the equipment; in terms of sound effects, smooth movement helps to maintain a stable relative position between the speaker 4 and the PCB board 5, thereby ensuring the consistency and reliability of sound propagation, and can better achieve fine adjustment of the sound to meet the sound requirements in different scenarios; in terms of maintenance, when the speaker 4 or the loudspeaker support plate 41 needs to be repaired or replaced, it can be easily disassembled and installed through the structure of the guide rails 11 and the guide blocks 12, which improves the efficiency and convenience of maintenance work.

[0076] See also Figure 2The second translation driving mechanism 7 includes multiple second motors 71, multiple screw rods 72 and multiple nuts 73; each second motor 71 corresponds to one of the screw rods 72, each screw rod 72 corresponds to one of the nuts 73, and each nut 73 is fixed on the speaker support plate 41.

[0077] First, by setting a plurality of screw rods 72 for adjustment, the different positions of the speaker support plate 41 can be finely adjusted, thereby achieving a higher adjustment accuracy. Whether in the process of the speaker 4 approaching or moving away from the PCB board 5, or when the sound effect needs to be fine-tuned, this can provide a higher adjustment accuracy and meet more complex application requirements. At the same time, the synergistic effect of the plurality of second motors 71 and the screw rods 72 can ensure that the movement of each part of the speaker support plate 41 during the movement is highly synchronized, which is not only conducive to improving the stability and consistency of the sound effect, but also can avoid equipment failure or performance degradation caused by the asynchronous movement of different parts. When a failure occurs, the parts can be repaired or replaced separately without affecting the overall operation. Secondly, the combination of the plurality of screw rods 72 and the nuts 73 can evenly transfer the power generated by the second motor 71 to the speaker support plate 41, avoiding the occurrence of local excessive force damage, thereby extending the service life of the equipment and improving the reliability and durability of the equipment.

[0078] Exemplarily, a mobile platform can be provided under the speaker support plate 41 to simultaneously move the speaker support plate 41 and maintain its stability, but the space occupied by the mobile platform is relatively large, which will compress the layout space of other components inside the device to a certain extent, and may increase the limitations of the overall structural design. Moreover, the heavier mobile platform will bring a greater load to the device as a whole, put forward higher requirements on the support structure and drive mechanism of the device, and increase the manufacturing cost and energy consumption. The combination of the guide rail 11 and the guide block 12 has a compact structure, occupies a small space, and will not cause too much interference to the internal space of the device. At the same time, its light weight can effectively reduce the overall burden of the equipment, reduce driving energy consumption, and improve the operating efficiency and stability of the equipment, making it more suitable for use in sound-transmitting display devices.

[0079] In one embodiment, part of the guide rail 11 is located directly below the speaker support plate 41, and part of the guide rail 11 is located directly above the speaker support main board. The guide rails 11 located directly below and directly above the speaker support plate 41 form a stable clamping structure to constrain the speaker support plate 41 from both the upper and lower directions. When the speaker support plate 41 is subjected to external force or is in motion, the combined action of the upper and lower guide rails 11 can effectively prevent it from shaking or tilting left and right, greatly enhancing the stability of the support main board, ensuring that it always remains in the correct position, and avoiding equipment failure or damage caused by overturning.

[0080] To sum up, another sound-transparent display device provided in an embodiment of the present application uses a first translation drive mechanism 6 and a second translation drive mechanism 7 to simultaneously adjust the sound cavity space between the PCB board 5, the screen mask 31 and the speaker 4, thereby increasing the processing method for the sound waves of the speaker 4 and further enriching the sound processing effect.

[0081] In one embodiment, Figure 6 As shown, the embodiment of the present application also provides a sound transmission control method applied to the above-mentioned sound transmission display device, the method is applied to the controller of the sound transmission display device, and the method includes the following steps:

[0082] S610, obtaining video data to be played;

[0083] S620, processing the video data to be played and generating audio-visual control instructions, the audio-visual control instructions are used to control the lamp beads to play the video images corresponding to the audio and video band in real time and control the sound-transparent display device to adjust to the position of presenting the corresponding audio and video band in real time.

[0084] Preferably, the image content and the corresponding audio and video band information in the film and television data are identified, and the cavity space requirements suitable for the propagation of sound in this frequency band are determined by analyzing the characteristics of different frequency bands of sound. For example, low-frequency sound may require a larger cavity space to enhance the resonance effect, while high-frequency sound may require a relatively small cavity space to avoid excessive reflection. Based on this, corresponding cavity space adjustment instructions are generated. These instructions will be conveyed to the relevant components of the sound-transmitting display device, such as the first translation drive mechanism, so that it adjusts the distance between the screen mask and the PCB board, thereby changing the size of the front cavity to meet the cavity space required for a specific audio and video band.

[0085] At the same time, as the cavity space is adjusted, the audio-visual control instructions will also cause the lamp bead display effect to change accordingly. Because the change of the cavity space will affect the propagation of sound and the overall audio-visual effect, the lamp bead display effect needs to be adjusted according to the new space state to ensure that the image and sound are always coordinated and consistent, bringing users a more perfect audio-visual experience.

[0086] To summarize, the sound transmission control method provided in the present application processes film and television data to obtain the relationship between image display effect and audio band presentation effect, and generates corresponding device parameters according to the relationship to control the device to adjust the cavity space size formed by the driving mechanism and PCB and the display effect of the lamp beads in real time to ensure diversified processing of sound and normal display and projection, thereby increasing the richness of sound effects and making the film and television effects more natural.

[0087] See also Figure 7 , further, processing the video data to be played and generating audio-visual control instructions includes the following steps:

[0088] S710: Extract features of a corresponding area of ​​the video data to be played based on a preset extraction rule to obtain video features, where the video features include image features and audio features.

[0089] Preferably, for image features, a local binary pattern (Local Binary Pattern, LBP) algorithm can be used for extraction to analyze the color, texture, shape and other features of the image. For example, by identifying different color distributions, the outline of objects in the image and the fineness of the texture, image features can be extracted. For audio features, a Mel Frequency Cepstral Coefficients (MFCC) algorithm can be used, which first frames and windows the audio signal, and then performs a fast Fourier Transform (FFT) on each audio frame to convert the time domain signal into a frequency domain signal. Then, the frequency domain signal is filtered by a Mel filter bank, and the measurement method of the frequency domain signal is converted from frequency to Mel scale to obtain a filtered signal. Finally, a discrete cosine transform (DCT) is performed on the filtered signal to obtain the MFCC features of the audio, which can better reflect the timbre, tone and other features of the audio.

[0090] S720, processing the film and television features based on a machine learning algorithm to obtain an audio-visual mapping relationship, where the audio-visual mapping relationship is used to indicate a real-time correspondence between display parameters required to display an image and an audio frequency band;

[0091] Preferably, a support vector machine (SVM) algorithm can be used for processing. First, a large number of annotated film and television data samples are collected. The annotation content includes different audio features and corresponding display parameters for training. The audio features can be the frequency distribution and energy distribution of the sound, and the display parameters can be the screen brightness, contrast, and color saturation composed of lamp beads.

[0092] In a specific embodiment, the trained SVM model can predict the display parameters corresponding to the new film and television features based on the audio features. If low-frequency audio is detected, it means that a larger cavity space may be required between the screen and the PCB board. At this time, the model outputs corresponding display parameter adjustment suggestions, such as increasing screen brightness, enhancing contrast, etc., to avoid the picture appearing abrupt due to distance changes. In this way, a real-time correspondence between audio frequency bands and display parameters is established, that is, an audio-visual mapping relationship.

[0093] S730, the audio-visual mapping relationship is processed to obtain a sound-transmitting control parameter, where the sound-transmitting control parameter is used to indicate a working parameter for controlling the real-time playback of a video image corresponding to the audio and video band and adjusting a sound-transmitting display device to present the corresponding audio and video band.

[0094] Preferably, the sound transmission control parameters include display control parameters and drive control parameters, and obtaining the sound transmission control parameters includes the following steps:

[0095] S740. Obtain a first position parameter of the sound-transparent display device, where the first position parameter is used to indicate the distance between the PCB board and the screen mask and the distance between the PCB board and the speaker support board, which are pre-stored after the sound-transparent display device last worked.

[0096] S750: Input the first position parameter and the audio-visual mapping relationship into a preset control model for processing to generate a driving control parameter.

[0097] Preferably, the drive control parameters are divided into first control drive parameters and second control drive parameters.

[0098] like Figure 8a As shown, the first control driving parameter is obtained by the following steps:

[0099] S810. Process the audio-visual mapping relationship based on a neural network algorithm to obtain a second position parameter, where the second position parameter is used to indicate the distance between the PCB board and the screen mask and the distance between the PCB board and the speaker support plate when the first translation drive mechanism is adjusted to present a corresponding audio frequency band.

[0100] Exemplarily, the audio-visual mapping relationship may be input into a pre-trained neural network for processing, and the processing process includes the following steps:

[0101] Step 1: Data preparation: Collect a large amount of sample data in advance. Each sample contains a feature description of a specific sound frequency band and the distance between the PCB board and the screen mask and the distance between the PCB board and the speaker support board when manually setting various sound effects.

[0102] Among them, for the extraction of audio band features, the Fast Fourier Transform (FFT) algorithm can be used. After the sound signal is converted by FFT, the amplitude and phase information of different frequency components can be obtained. Features such as frequency range and energy distribution can be extracted from it. For example, the ratio of the total energy in a specific frequency interval to the total energy can be calculated as a feature. The extracted features are normalized so that the data is within a certain range, which is convenient for neural network training.

[0103] Step 2: Construct a neural network model; a multi-layer feedforward neural network can be used, and the number of neurons in the input layer corresponds to the characteristic dimensions of the audio band, which may include frequency components, harmonic content, etc. Several hidden layers are set in the middle to effectively learn the complex relationship between the audio band and the distance parameter. The output layer has two neurons, corresponding to the distance d1 between the PCB board and the screen mask and the distance d2 between the PCB board and the speaker support board.

[0104] Step three, randomly initialize the network parameters; for example, randomly initialize the weights and bias parameters in the network. Preferably, for the weight matrix W, the Xavier initialization method can be used. Assuming that there are n neurons in the input layer and m neurons in the output layer, the initial values ​​of the elements of the weight matrix W can be set to values ​​randomly sampled from a normal distribution with a mean of 0 and a variance of 2 / (m+n). This allows the signal to maintain approximately the same variance as it propagates in the network, avoiding the problem of gradient vanishing or exploding. The bias vector b is initialized to a smaller random value, such as a value sampled from a normal distribution with a mean of 0 and a variance of 0.1.

[0105] Step 4: Input the sound frequency band feature of a training sample into the network, perform forward propagation through the calculation of each layer, and then activate the ReLU (Rectified Linear Unit) function to obtain the output of the layer. The activation function introduces nonlinearity, allowing the network to learn complex mapping relationships, and gradually pass the output values ​​to the output layer to obtain the predicted distance between the PCB board and the screen mask and the distance between the PCB board and the speaker support board. The calculation formulas and activation function formulas of each layer are as follows:

[0106] z=Wx+b

[0107] a=f(z)

[0108] f(z)=max(0,z)

[0109] Among them, for the input layer, x is the input sound frequency band feature, for other layers, x is the output of the previous layer, W is the weight matrix, b is the bias vector, and a is the output of each layer.

[0110] Step 5: Calculate the loss function based on the predicted distance value output by the network and the actual labeled distance value. For example, let the predicted distance output by the network be and The actual annotation distances are d1 and d2, so the loss function is That is, mean square error. This loss function measures the difference between the network's predicted value and the actual value, and the loss function can be minimized during the training process.

[0111] Step 6: Based on the loss function, starting from the output layer, reversely calculate the gradient of the weight and bias of each parameter to the loss. Through the chain rule, the gradient of the loss function to the output layer is back-propagated to each hidden layer in turn, and the gradient of the parameters of each layer is calculated, so that the neural network can adjust the parameters according to the loss to better fit the training data. According to the chain rule, the gradients of the loss function to them are:

[0112]

[0113] z out =W out a last +b out

[0114] Among them, W out is the weight matrix of the output layer, b out is the bias vector of the output layer, a last is the output of the previous layer.

[0115] Step 7: Parameter update: Preferably, Stochastic Gradient Descent (SGD) can be used to update the parameters, and the weights and bias parameters in the network are updated according to the calculated gradients. For the weight matrix W, the update formula is: Where α is the learning rate, which controls the step size of each parameter update. For the bias vector b, the update formula is

[0116] For example, the learning rate α is a hyperparameter that can be adjusted based on experience or through experiments. If the learning rate is too large, the parameters may be updated too quickly and fail to converge to the optimal solution; if the learning rate is too small, the training process may be very slow.

[0117] Step 8: Repeat steps 4 to 7 above to train the entire training data set for multiple epochs. In each epoch, each sample in the training set is forward propagated, loss is calculated, back propagated, and parameters are updated. As the training progresses, the loss function gradually decreases and the prediction ability of the network continues to improve. The training process ends when the loss function converges to a smaller value or reaches the preset number of training times. During the training process, the performance of the model on the validation set can be regularly evaluated to adjust hyperparameters and prevent overfitting.

[0118] S820: Analyze and process the first position parameter and the second position parameter to generate a first driving control parameter.

[0119] Preferably, the parameter variation of the first position parameter and the second position parameter is calculated, and the first drive control parameter can be determined according to the variation. Assuming that the parameter variation is Δd and the pitch of the thread segment is l, the corresponding required number of revolutions is At the same time, the rotation direction of the motor is determined according to the direction of displacement, and the first driving control parameters of the first translation drive mechanism are obtained by combining the number of revolutions, rotation direction and working parameters of the motor itself to adjust the first translation drive mechanism to present the corresponding sound frequency band. The working parameters of the motor include.

[0120] like Figure 8b As shown, the second control driving parameter is obtained by the following steps:

[0121] S830, processing the audiovisual mapping relationship based on a neural network algorithm to obtain a third position parameter, where the third position parameter is used to indicate the distance between the PCB board and the screen mask and the distance between the PCB board and the speaker support board when the first translation drive mechanism and the second translation drive mechanism are jointly adjusted to present a corresponding audio frequency band;

[0122] S840: Analyze and process the first position parameter and the third position parameter to generate a second drive control parameter.

[0123] S760, updating the first position parameter based on the drive control parameter;

[0124] S770: Process the image feature based on the first position parameter to obtain a display control parameter, where the display control parameter is used to indicate real-time adjustment of display parameters for playing the video image under the first position parameter.

[0125] Preferably, when the distance between the PCB board and the screen mask changes, the attenuation degree of the light during the propagation process will change. For example, if the distance increases, the light may become relatively dim, and at this time, the brightness of the lamp beads needs to be increased to ensure that the display effect of the image does not appear abrupt. At the same time, the contrast of the image may be reduced, and the color may appear dim because the interference of the background light may increase. At this time, the contrast and color saturation can be appropriately increased to enhance the layering and clarity of the image, making the image more vivid and vivid. A color saturation adjustment ratio can also be determined according to the change in distance to adjust the color output of the lamp beads.

[0126] Real-time adjustment of display control parameters based on the first position parameters can ensure that the image maintains high-quality display when the distance between the PCB board and the screen mask changes, avoid problems such as blur and dimness, improve the user's visual experience, enhance the adaptability of the equipment, adapt to different environments and installation conditions, and facilitate maintenance and upgrades.

[0127] In summary, the sound transmission control method provided by the present application processes the film and television data to obtain the relationship between the image display effect and the sound band presentation effect, and generates the control parameters of the first translation drive mechanism and the second translation drive mechanism according to the relationship to jointly adjust the size of the sound cavity space formed between the PCB board, the screen mask and the speaker to achieve diversified processing of the sound in more ways; and by timely adjusting the control parameters of the lamp beads based on the size of the sound cavity space to ensure high-quality image display effects, the richness of the sound effects is increased while making the film and television effects more natural.
