[0044] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0045] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0046] Embedded installation of display devices means embedding the display devices into walls or furniture structures to achieve seamless integration of the display devices and the home environment, reduce the occupation of living space by the display devices, and make the home environment more tidy and beautiful.

[0047] However, due to the differences in the size of the space reserved in walls or furniture, as well as the inconsistency in the size specifications of display devices on the market, the limitations of physical spaces such as walls and cabinets often have an adverse effect on the sound transmission quality of display devices, which manifests as muffled sound, seriously affecting the user's auditory experience.

[0048] In summary, how to improve the sound effect of embedded display devices to enhance the user's auditory experience has become a technical problem that urgently needs to be solved in this field.

[0049] The main solution of the embodiment of the present application is: after determining that the display device is installed in an embedded manner, determine the sound output direction of the speaker of the display device; when the sound output direction of the speaker is toward the closed side of the embedded groove, determine the sound effect control strategy according to the distance between the display device and the side walls of the embedded groove, and perform sound effect control according to the sound effect control strategy.

[0050] The embodiment of the present application provides a solution, which realizes precise optimization of the sound effect of the embedded display device and improves the sound transmission quality of the embedded display device by identifying the sound output direction of the speaker of the embedded display device and formulating a sound effect control strategy according to the distance between the display device and the side wall of the embedded groove, thereby improving the user's auditory experience when using the embedded display device.

[0051] Based on this, the present application embodiment provides a method for controlling sound effects. Figure 1 , Figure 1 This is a flow chart of the first embodiment of the sound effect control method of the present application.

[0052] In this embodiment, the sound effect control method includes steps S10 to S20:

[0053] Step S10, after determining that the display device is installed in an embedded manner, determining the sound output direction of the speaker of the display device;

[0054] After determining that the display device is installed in an embedded manner, determine the sound output direction of the speaker of the display device.

[0055] Among them, before determining the direction of the speaker sound, it is necessary to confirm whether the display device has an external sound device, such as an external speaker, Bluetooth headset or other audio output device. If the display device does not have an external sound device, that is, the display device relies on the built-in speaker for sound output, then determine the speaker sound direction of the display device to determine the sound effect control strategy based on the relative position relationship between the speaker sound direction and the surrounding environment.

[0056] In a feasible embodiment, before step S10, steps A10 to A20 may be further included:

[0057] Step A10, detecting the distance between the display device and the surrounding physical medium;

[0058] Step A20, determining whether the display device is installed in an embedded manner according to the distance.

[0059] The distance between the display device and the surrounding physical medium is detected, and whether the display device is installed in an embedded manner is determined according to the distance between the display device and the surrounding physical medium.

[0060] Specifically, the built-in sensors of the display device can be used to detect the distance between the display device and the surrounding physical medium. For example, a distance sensor can be used to measure the actual distance between the display device and surrounding objects (such as walls, cabinets, etc.), and a displacement sensor can be used to collect the position and displacement data of the display device to assist in determining the installation status of the display device. A light sensor can also be used to assist in determining whether the display device is surrounded by the surrounding physical medium, that is, based on the results of distance measurement, position analysis, and light information verification, a comprehensive judgment can be made as to whether the display device is in an embedded installation state.

[0061] Step S20, when the sound output direction of the speaker is toward the closed side of the embedded groove, a sound effect control strategy is determined according to the distance between the display device and each side wall of the embedded groove, and sound effect control is performed according to the sound effect control strategy.

[0062] It should be noted that the embedded groove refers to a physical structure that accommodates the display device, which may be a wall, a furniture cabinet or other physical structure. The embedded groove includes at least one open side for displaying the display screen of the display device. The embedded groove may include multiple closed sides to partially or completely wrap the body of the display device.

[0063] When it is determined that the speaker sound output direction of the display device is toward the closed side of the embedded groove, the sound effect control strategy is determined according to the distance between the display device and the side walls of the embedded groove, and the sound effect control is performed according to the determined sound effect control strategy.

[0064] In addition, for display devices that are not equipped with sensors, it is possible to determine whether the display device is embedded based on the input information provided by the user. The user can manually input whether the display device is embedded and the specific distance between it and the side walls of the embedded groove according to the actual installation situation, and then determine the sound effect control strategy based on this information.

[0065] In a feasible embodiment, step S10 may further include step S30:

[0066] Step S30, when the sound output direction of the speaker is toward the open side of the embedded groove, determining the sound effect control strategy as the standard sound effect control strategy.

[0067] In actual application scenarios, the open side of the embedded groove is usually the side facing the display screen of the display device, and the sound output direction of the speaker is facing the open side of the embedded groove, that is, the sound output direction of the display device is facing forward. In other feasible implementation scenarios, if the embedded groove has multiple open sides, for example, the upper side of the embedded groove is not closed, then when the sound output direction of the speaker is facing upward, it can also be determined that the sound output direction of the speaker is facing the open side of the embedded groove.

[0068] When it is determined that the sound output direction of the speaker of the display device is toward the open side of the embedded groove, that is, the sound output of the display device is not blocked and the output sound is a normal sound effect, the current sound effect control strategy is determined to be the standard sound effect control strategy, and there is no need to adjust the sound effect adjustment parameters such as virtual surround, vocal enhancement, and bass enhancement of the display device.

[0069] In summary, the embodiment of the present application realizes precise optimization of the sound effect of the embedded display device by identifying the sound output direction of the speaker of the embedded display device and formulating a sound effect control strategy according to the distance between the display device and the side wall of the embedded groove, thereby improving the sound transmission quality of the embedded display device and improving the user's auditory experience when using the embedded display device.

[0070] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. On this basis, step S20 can include steps S201 to S204:

[0071] Step S201, when the sound output direction of the speaker is toward the closed side of the embedded groove, determining a first distance between a display screen of the display device and a first open side of the embedded groove;

[0072] When the sound output direction of the speaker of the display device is toward the closed side of the embedded groove, that is, the sound output of the display device is blocked, which has an adverse effect on the sound quality of the output sound, the first distance between the display screen of the display device and the first open side of the embedded groove is first determined, wherein the first open side of the embedded groove refers to the side to which the display screen of the display device faces, and the first distance reflects the embedding depth of the display device in the embedded groove.

[0073] Step S202, when the first distance exceeds a preset first distance value, determining a second distance between a sound output side of a speaker of the display device and a first closed side of the embedded groove;

[0074] If the first distance exceeds the preset first distance value, the second distance between the speaker sound output side of the display device and the first closed side of the embedded groove is further determined, wherein the first distance value is determined based on the performance parameters of the display device, and is not specifically limited in the present embodiment. The speaker sound output side may be the upper side, lower side, left side and / or right side of the display device, and the first closed side of the embedded groove refers to the side corresponding to the speaker sound output side. The second distance reflects the situation where the output sound of the display device is blocked.

[0075] Step S203, when the second interval exceeds a preset second distance value, determining the sound effect control strategy to be a standard sound effect control strategy;

[0076] It should be noted that the second distance value is the maximum distance at which the closed side embedded in the groove will affect the sound effect of the speaker. When the second distance between the sound-emitting side of the speaker and the first closed side exceeds the second distance value, it means that the distance between the speaker and the closed side is far and the sound propagation will not be affected.

[0077] When the second interval exceeds a preset second distance value, the sound effect control strategy is determined to be a standard sound effect control strategy, wherein the second distance value is determined based on performance parameters of the display device, which is not specifically limited in this embodiment.

[0078] Step S204: when the second interval does not exceed the preset second distance value, determining the sound effect control strategy as the first sound effect control strategy.

[0079] When the second spacing does not exceed the second distance value, it means that the distance between the speaker and the closed side is relatively close and the sound propagation will be affected. At this time, the sound effect control strategy is determined to be the first sound effect control strategy. The sound output effect of the display device is adjusted through the first sound effect control strategy to ensure the sound output quality.

[0080] In a feasible embodiment, step S204 may include step S2041:

[0081] Step S2041, when the second distance does not exceed the preset second distance value, determine that the sound effect control strategy is the first sound effect control strategy, the first sound effect control strategy includes virtual surround sound effect adjustment, human voice effect adjustment and bass sound effect adjustment, and the adjustment amplitude of each sound effect decreases as the second distance increases.

[0082] It should be noted that for embedded display devices, if the niche (i.e. the side wall embedded in the groove) has a great influence on the output sound of the display device, resulting in muffled sound, a larger virtual surround amplitude can be set to produce a stronger virtual sound to break through the sound blockage of the niche, making the sound more transparent and greatly improving the problem of muffled sound; vocal enhancement can make the output sound of vocal dialogues more prominent and clearer to hear. Increasing the amplitude of vocal enhancement can also help improve the problem of muffled sound; bass enhancement is used to adjust the amplitude of the low-frequency band. Multiple reflections of the niche may cause excessive low frequencies or even low-frequency buzzing. This problem can be improved by reducing the bass enhancement amplitude.

[0083] When the second distance does not exceed the second distance value, the sound effect control strategy is determined to be the first sound effect control strategy. The first sound effect control strategy can specifically optimize the virtual surround sound, human voice effect and bass sound effect of the display device, and adaptively adjust the control amplitude according to the second distance. The adjustment amplitude of each sound effect decreases as the second distance increases.

[0084] For example, based on the performance parameters of the display device and the actual needs of the user, the standard sound effect adjustment strategy is set as follows: the virtual surround sound effect amplitude is x1, the human voice sound effect amplitude is x2, and the bass sound effect amplitude is x3. When there is no obstruction on the sound output side of the speaker of the display device or the distance between the obstruction and the sound output side of the speaker is far enough not to affect the sound quality of the output sound, the sound effect of the output sound is adjusted according to the standard sound effect adjustment strategy.

[0085] When the first distance exceeds the first distance value and the second distance does not exceed the second distance value, the sound effect adjustment strategy is determined as the first sound effect adjustment strategy. The first sound effect adjustment strategy includes increasing the adjustment amplitude of the virtual surround sound effect, increasing the adjustment amplitude of the human voice sound effect, and decreasing the adjustment amplitude of the bass sound effect. Since the greater the second distance, the smaller the influence of the niche on the sound output, the adjustment amplitude decreases as the second distance increases.

[0086] In a preferred embodiment, the display device is installed in an embedded manner. The structural top view of the display device and the embedded groove is as Figure 2 shown. In the figure, the sound output side of the speaker of the display device is the right side. d represents the depth of the embedded groove, h represents the distance between the back side of the display device and the back cabinet, t represents the distance between the display screen of the display device and the back cabinet, w represents the distance between the sound output side of the speaker of the display device and the right cabinet, that is, the second distance, d - t represents the distance between the display screen of the display device and the opening, that is, the first distance. The first distance value is set to 5 cm, and the second distance value is set to 9 cm. Usually, to ensure that the display device can be completely embedded and the buttons on the side of the device can be operated, there is at least a 2 cm gap between the embedded groove and the display device.

[0087] In this scenario, when d - t > 5 cm, if w ≥ 9 cm, the sound effect is adjusted according to the standard sound effect adjustment strategy; if w < 9 cm, the sound effect is adjusted according to the first sound effect adjustment strategy.

[0088] When d - t > 5 cm, the sound effect adjustment strategy is shown in Table 1:

[0089] Table 1

[0090] w≥9cm w=2cm 2cm<w<9cm Virtual Surround x1 x1+y1 x1+y1*z1 Human voice effect x2 x2+y2 x2+y2*z2 Bass sound effects x3 x3-y3 x3-y3*z3

[0091] Among them, x1 is the virtual surround sound effect amplitude under the standard sound effect adjustment strategy, x2 is the human voice sound effect amplitude under the standard sound effect adjustment strategy, x3 is the bass sound effect amplitude under the standard sound effect adjustment strategy. When w = 2, the virtual surround sound effect amplitude is corrected to x1 + y1, the human voice sound effect amplitude is corrected to x2 + y2, and the bass sound effect amplitude is corrected to x3 - y3. When 2 cm < w < 9 cm, the correction values of each sound effect amplitude are reduced proportionally, where 0 < z1, z2, z3 < 1.

[0092] In a feasible embodiment, step S201 may further include steps S205 to S206:

[0093] Step S205, when the first distance does not exceed a preset first distance value, determining a third distance between the back surface of the display device and the second closed side of the embedded groove;

[0094] If the first distance does not exceed the preset first distance value, a third distance between the back side of the display device and the second closed side of the embedded groove is further determined, wherein the second closed side of the embedded groove refers to a side adjacent to the back side of the display device.

[0095] Step S206: When the third distance does not exceed the preset third distance value, determine that the sound effect control strategy is the standard sound effect control strategy.

[0096] It should be noted that the third distance value is preferably zero. When the first distance does not exceed the first distance value, it means that the display screen of the display device is very close to or flush with the wall or cabinet surface. If the third distance is zero, that is, the rear shell of the display device is close to the second closed side of the embedded groove, since the sound has only a forward propagation path at this time, and the display device is not embedded deeply, the sound is easier to propagate out of the niche. In this case, no correction is required, and the sound effect control strategy at this time is determined to be the standard sound effect control strategy.

[0097] In a feasible embodiment, step S205 may further include steps S207 to S209:

[0098] Step S207, when the third distance exceeds a preset third distance value, determining a second distance between the sound output side of the speaker of the display device and the first closed side of the embedded groove;

[0099] When the third distance exceeds the third distance value, a second distance between the sound output side of the speaker of the display device and the first closed side of the embedded groove is further determined.

[0100] Step S208, when the second distance exceeds a preset fourth distance value, determining the sound effect control strategy to be a standard sound effect control strategy;

[0101] When the second distance exceeds a fourth distance value, the sound effect control strategy is determined to be a standard sound effect control strategy, wherein the fourth distance value is smaller than the second distance value.

[0102] Step S209: when the second distance does not exceed a preset fourth distance value, determining the sound effect control strategy to be the second sound effect control strategy.

[0103] When the second distance does not exceed the fourth distance value, it indicates that the distance between the speaker and the closed side is relatively close, and the sound propagation will be affected. At this time, the sound effect adjustment strategy is determined to be the second sound effect adjustment strategy, and the sound output effect of the display device is adjusted through this second sound effect adjustment strategy to ensure the sound output quality.

[0104] When the first distance does not exceed the first distance value, the third distance exceeds the third distance value, and the second distance does not exceed the fourth distance value, the sound effect adjustment strategy is determined to be the second sound effect adjustment strategy. The second sound effect adjustment strategy includes increasing the adjustment amplitude of the virtual surround sound effect, increasing the adjustment amplitude of the human voice sound effect, and decreasing the adjustment amplitude of the bass sound effect. Since the larger the second distance, the smaller the influence of the niche on the sound output, the adjustment amplitude decreases as the second distance increases.

[0105] Exemplarily, when d - t ≤ 5 cm, that is, at this time, the display screen of the display device is very close to or flush with the wall or cabinet surface. If h > 0, that is, the third distance exceeds the third distance value, and if w ≥ 5 cm, that is, the second distance exceeds the fourth distance value, the sound effect is adjusted according to the standard sound effect adjustment strategy. If w < 5 cm, that is, the second distance does not exceed the fourth distance value, the sound effect is adjusted according to the second sound effect adjustment strategy.

[0106] When d - t ≤ 5 cm, the sound effect adjustment strategy is shown in Table 2:

[0107] Table 2

[0108] w≥5cm w=2cm 2cm<w<5cm Virtual Surround x1 x1+y4 x1+y1*z4 Vocal Enhancement x2 x2+y5 x2+y2*z5 Bass Boost x3 x3-y6 x3-y3*z6

[0109] Among them, x1 is the virtual surround sound effect amplitude under the standard sound effect adjustment strategy, x2 is the human voice sound effect amplitude under the standard sound effect adjustment strategy, and x3 is the bass sound effect amplitude under the standard sound effect adjustment strategy. When w = 2, the virtual surround sound effect amplitude is corrected to x1 + y4, the human voice sound effect amplitude is corrected to x2 + y5, and the bass sound effect amplitude is corrected to x3 - y6. When 2 cm < w < 5 cm, the correction values of each sound effect amplitude are reduced in equal proportion, 0 < z4, z5, z6 < 1.

[0110] It is worth mentioning that the various parameters (such as the first distance value, the second distance value, the third distance value, the fourth distance value, etc.) mentioned in this embodiment can be obtained through experimental verification based on the performance parameters of the display device and the actual application scenario. The specific data of the various parameters mentioned in this embodiment are all a preferred embodiment and are not specifically limited.

[0111] In the present embodiment, since the distance between the display device and the embedded groove is different after the display device is installed in the embedded manner, the degree of influence of the side walls of the embedded groove on the sound output of the display device is also different. The present embodiment adaptively adjusts the sound output sound effect according to the distance value between the display device and the side walls of the embedded groove, and can adjust the virtual surround, human voice effect and bass sound effect of the sound output of the display device respectively, so as to enhance the sound effect of the embedded display device and improve the user's auditory experience.

[0112] For example, to help understand the implementation process of the sound effect control method obtained by combining the above embodiments, take the display device as a TV as an example, the TV is embedded, the back of the TV is a wall, the surroundings are cabinets, and the TV display screen faces the open side of the embedded groove. Assume that the first distance value is 5cm, the second distance value is 9cm, the third distance value is 0cm, and the fourth distance value is 5cm. Please refer to Figure 3 , specifically:

[0113] First, it is determined that the distance between the open side of the embedded groove and the TV display screen is greater than 5 cm. When the distance between the open side and the TV display screen is greater than 5 cm, it is determined whether the distance between the edge of the TV in the direction of the sound of the TV speaker and the cabinet is greater than 9 cm. If it is greater than 9 cm, the standard sound effect control strategy is adopted; if it is not greater than 9 cm, the first sound effect control strategy is adopted; when the distance between the open side and the TV display screen is not greater than 5 cm, it is determined whether the back shell of the TV is close to the wall. If the back shell of the TV is close to the wall, the standard sound effect control strategy is adopted. If the back shell of the TV is not close to the wall, it is determined whether the distance between the edge of the TV in the direction of the sound of the TV speaker and the cabinet is greater than 5 cm. If it is greater than 5 cm, the standard sound effect control strategy is adopted. If it is not greater than 5 cm, the second sound effect control strategy is adopted. Therefore, the TV sound effect is automatically adjusted according to the distance between the TV and the side walls of the embedded groove to reduce the adverse effects of the embedded installation on the TV output sound and improve the user's auditory experience.

[0114] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the sound effect control method of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.

[0115] The present application also provides a sound effect control device, please refer to Figure 4 , the sound effect control device comprises:

[0116] The sound output direction determination module 10 is used to determine the sound output direction of the speaker of the display device after determining that the display device is installed in an embedded manner;

[0117] The audio control module 20 is used to determine the sound effect control strategy according to the distance between the display device and the side walls of the embedded groove when the sound output direction of the speaker is toward the closed side of the embedded groove, and perform sound effect control according to the sound effect control strategy.

[0118] Optionally, the audio control module 20 is further used to:
