Description

Technical Field

[0001] This invention relates to the field of sound adjustment technology, and in particular to a sound adjustment device and a sound adjustment method. Background Technology

[0002] In the process of modern urbanization and industrial development, environmental noise pollution has become an increasingly serious problem. Environmental noise not only affects human quality of life and health, but also has a wide-ranging and profound negative impact on economic activities. Long-term exposure to high-intensity noise environments, such as traffic noise, industrial noise, and construction site noise, can lead to hearing damage. Studies have shown that continuous exposure to noise above 85 decibels significantly increases the risk of hearing damage and noise-induced deafness. Meanwhile, in certain specific scenarios, it is necessary to transmit indoor sound to the outside or vice versa. However, with reduced absorption by walls, the sound that can penetrate the walls becomes less audible, thus requiring structures to enhance sound transmission.

[0003] Existing noise reduction and enhancement technologies typically involve users wearing headphones and achieving noise reduction through passive noise-absorbing structures and active noise reduction functions on the headphones, while enhancing transparency through active enhancement functions. However, wearing headphones for extended periods is not only inconvenient for users' daily activities but also affects their ear health. Therefore, existing noise reduction and sound enhancement methods suffer from inconvenience and health risks. Summary of the Invention

[0004] The main objective of this invention is to propose a sound adjustment device and method, aiming to solve the problems of inconvenience and health impact of existing noise reduction and sound enhancement methods.

[0005] To achieve the above objectives, the present invention provides a sound adjustment device, the sound adjustment device comprising:

[0007] A first adjustment component is installed inside the inner shell;

[0008] The second adjustment component is installed inside the housing. The second adjustment component includes a vibration sensor and a sound sensor. The vibration sensor is used to acquire vibration information and record the first moment when the vibration information is acquired for the first time. The sound sensor is used to acquire sound information and record the second moment when the sound information is acquired for the first time. The vibration sensor and the sound sensor are set at intervals so that the first moment and the second moment are different.

[0009] The controller includes a first adjustment component and a second adjustment component, both of which are electrically connected to the controller. The controller is used to control the first adjustment component to vibrate and the second adjustment component to emit sound waves for sound adjustment based on the vibration information, the first moment, the sound information, and the second moment.

[0010] In one embodiment, the sound sensor sends the sound information spectrum Pn, amplitude Dn, and second time Tn to the controller, and the vibration sensor sends the vibration information spectrum Pm, amplitude Dm, and first time Tm to the controller. The controller acquires sound information and vibration information where the difference between Pn and Pm is within a preset difference range, calculates the difference between Tn and Tm of the sound information and the vibration information, as well as the difference between Dn and Dm, and determines the sound wave source of the sound information and vibration information, wherein the sound wave source is indoor sound wave or outdoor sound wave. The controller controls the first adjustment component to generate vibration and controls the second adjustment component to emit sound waves to adjust the sound source according to the adjustment mode.

[0011] In one embodiment, the first adjustment component includes an oscillator electrically connected to the controller and used to generate vibration;

[0014] In one embodiment, the second adjustment component further includes a second magnetic attractor disposed in the spacer portion, and the first adjustment component further includes a first magnetic attractor disposed corresponding to the second magnetic attractor. The second magnetic attractor can attract or de-attract with the first magnetic attractor to correspondingly attach or separate the spacer portion and the inner shell.

[0015] The present invention also proposes a sound adjustment method, applied to a sound adjustment device, the sound adjustment device comprising:

[0016] A housing, comprising an inner shell and an outer shell, wherein the outer shell is disposed on a wall and forms an installation cavity therebetween with the wall, the inner shell is housed within the installation cavity and disposed on the wall, a gap is formed between the inner shell and the outer shell, and a sound outlet is provided at the end of the outer shell away from the inner shell;

[0017] A first adjustment component is installed inside the inner shell;

[0018] The second adjustment component is installed inside the housing and includes a vibration sensor and a sound sensor, which are spaced apart.

[0019] The controller, wherein both the first regulating component and the second regulating component are electrically connected to the controller;

[0020] The sound adjustment method includes the following steps:

[0021] Vibration information is obtained through the vibration sensor and the first moment when the vibration information is first obtained is recorded; sound information is obtained through the sound sensor and the second moment when the sound information is first obtained is recorded, wherein the first moment and the second moment are different.

[0022] The controller determines the sound wave source of the sound information and the vibration information based on the vibration information and the first moment, as well as the sound information and the second moment, wherein the sound wave source is indoor sound wave or outdoor sound wave;

[0023] The controller controls the first regulating component to vibrate and the second regulating component to emit sound waves according to the adjustment mode.

[0024] In one embodiment, the vibration sensor is disposed close to the wall, and the sound sensor is disposed away from the vibration sensor along the thickness direction of the wall;

[0025] The step of the controller determining the sound wave source of the sound information and the vibration information based on the vibration information and the first moment, as well as the sound information and the second moment, includes:

[0026] The controller compares the first time Tm with the second time Tn;

[0027] If Tm is greater than Tn, then the sound wave source of the sound information and the vibration information is determined to be indoor sound wave;

[0028] If Tm is less than Tn, then the sound wave source of the sound information and the vibration information is determined to be outdoor sound wave.

[0029] In one embodiment, the vibration sensor is disposed close to the wall, and the sound sensor is disposed away from the vibration sensor along the thickness direction of the wall;

[0030] The steps of obtaining vibration information through the vibration sensor and recording the first moment when the vibration information is first obtained, and obtaining sound information through the sound sensor and recording the second moment when the sound information is first obtained, include:

[0031] The vibration sensor acquires the vibration information spectrum Pm, amplitude Dm, and first time Tm; the sound sensor acquires the sound information spectrum Pn, amplitude Dn, and second time Tn.

[0032] The step of the controller determining the sound wave source of the sound information and the vibration information based on the vibration information and the first moment, as well as the sound information and the second moment, includes:

[0033] The controller selects the vibration information and the sound information whose difference between Pm and Pn is within a preset difference range as the current vibration information and the current sound information, respectively.

[0034] The controller compares the first moment Tm and amplitude Dm of the current vibration information with the second moment Tn and amplitude Dn of the current sound information;

[0035] If Tm is greater than Tn and Dm is less than or equal to Dn, then the sound wave source of the current sound information and the current vibration information is determined to be the indoor sound wave;

[0036] If Tm is less than Tn and Dm is greater than Dn, then the sound wave source of the current sound information and the current vibration information is determined to be the outdoor sound wave.

[0037] In one embodiment, the first adjustment component includes an oscillator, and the second adjustment component further includes a sound-generating structure;

[0038] The steps of the controller controlling the first regulating component to vibrate and the second regulating component to emit sound waves according to the regulating mode include:

[0039] When the adjustment mode is indoor noise reduction mode, the indoor sound waves are filtered out, the controller controls the vibrator to generate vibrations opposite to the phase of the indoor sound waves, and controls the sound-emitting structure to emit sound waves opposite to the phase of the indoor sound waves.

[0040] When the adjustment mode is outdoor noise reduction mode, the outdoor sound waves are filtered out, the controller controls the vibrator to generate vibrations opposite to the phase of the outdoor sound waves, and controls the sound-emitting structure to emit sound waves opposite to the phase of the outdoor sound waves.

[0041] In one embodiment, the step of the controller controlling the first regulating component to vibrate and the second regulating component to emit sound waves according to the regulating mode further includes:

[0042] When the adjustment mode is the indoor transparency mode, the indoor sound waves are filtered out, the controller controls the vibrator to generate vibrations with the same phase as the indoor sound waves to emit a first compensation sound wave, and controls the sound-emitting structure to emit a sound wave with the opposite phase to the first compensation sound wave.

[0043] When the adjustment mode is outdoor transparent mode, the outdoor sound wave is filtered out, and the controller controls the vibrator to generate a vibration with the same phase as the outdoor sound wave to emit a second compensation sound wave.

[0044] When the adjustment mode is the full transparency mode, the indoor sound waves and the outdoor sound waves are simultaneously filtered out. The controller controls the vibrator to generate vibrations with the same phase as the indoor sound waves to emit a first compensation sound wave, and controls the vibrator to generate vibrations with the same phase as the outdoor sound waves to emit a second compensation sound wave.

[0045] The technical solution of this invention acquires vibration information through a vibration sensor and records the first moment of acquiring the vibration information. Then, it acquires sound information through a sound sensor and records the second moment of acquiring the sound information. Understandably, sound transmission takes time. Therefore, the vibration sensor and sound sensor, which are set at intervals, acquire the same sound wave in a sequential order. By comparing the first moment and the second moment, it is determined whether the sound sensor or the vibration sensor acquired the sound wave first, thereby determining whether the sound wave came from indoors or outdoors. Then, the controller controls the first adjustment component to generate vibration and controls the second adjustment component to emit sound waves for sound adjustment based on the vibration information and sound information. Specifically, it can generate vibrations with the same phase and emit sound waves with the same phase for enhancement, or generate vibrations with opposite phases and emit sound waves with opposite phases for noise reduction. This application uses an inner shell and a first noise reduction component installed in the wall to vibrate and cancel or enhance sound waves, and a second noise reduction component to emit sound waves to neutralize or enhance sound waves, thereby making the indoor environment quieter or allowing sound to penetrate the wall better. This application can achieve sound adjustment through external sound adjustment means, eliminating the need for users to wear headphones for extended periods, not affecting users' daily activities, making it more convenient to use, and it does not emit sound waves directly to the ears, thus not affecting the user's ear health.

[0059] Existing noise reduction and enhancement technologies typically involve users wearing headphones and achieving noise reduction through passive noise-absorbing structures and active noise reduction functions on the headphones, while enhancing transparency through active enhancement functions. However, wearing headphones for extended periods is not only inconvenient for users' daily activities but also affects their ear health. Therefore, existing noise reduction and sound enhancement methods suffer from inconvenience and health risks.

[0060] To address the above problems, the present invention proposes a sound adjustment device 100.

[0061] Please see Figure 1 In one embodiment of the present invention, the sound adjustment device 100 includes a housing 1, a first adjustment component 2, a second adjustment component 3, and a controller 4. The housing 1 includes an inner shell 11 and an outer shell 12. The outer shell 12 is disposed in a wall and forms a mounting cavity 13 with the wall. The inner shell 11 is housed in the mounting cavity 13 and disposed in the wall. A gap 14 is formed between the inner shell 11 and the outer shell 12. A sound outlet 121 is provided at the end of the outer shell 12 away from the inner shell 11. The first adjustment component 2 is installed in the inner shell 11. The second adjustment component 3 is installed in the outer shell 12. The second adjustment component 3 includes a vibration sensor 3. The system includes a vibration sensor 31 for acquiring vibration information and recording the first moment when the vibration information is first acquired, and a sound sensor 32 for acquiring sound information and recording the second moment when the sound information is first acquired. The vibration sensor 31 and the sound sensor 32 are spaced apart so that the first moment and the second moment are different. The first adjustment component 2 and the second adjustment component 3 are both electrically connected to the controller 4. The controller 4 is used to control the first adjustment component 2 to generate vibration and to control the second adjustment component 3 to emit sound waves for sound adjustment based on the vibration information, the first moment, the sound information, and the second moment.

[0062] The technical solution of this invention acquires vibration information through a vibration sensor 31 and records the first moment when the vibration information is acquired. Then, it acquires sound information through a sound sensor 32 and records the second moment when the sound information is acquired. It is understood that sound transmission takes time. Therefore, the vibration sensor 31 and the sound sensor 32, which are set at intervals, acquire the same sound wave in a sequential order. Therefore, by comparing the first moment and the second moment, it is determined whether the sound sensor 32 or the vibration sensor 31 acquired the sound wave first, thereby determining whether the sound wave came from indoors or outdoors. Then, the controller 4 controls the first adjustment component 2 to generate vibration and controls the second adjustment component 3 to emit sound waves for sound adjustment based on the vibration information and sound information. Specifically, it can generate vibrations with the same phase and emit sound waves with the same phase for enhancement, or generate vibrations with opposite phases and emit sound waves with opposite phases for noise reduction. This application uses an inner shell 11 and a first noise reduction component installed in the wall to vibrate and cancel or enhance sound waves, and a second noise reduction component to emit sound waves to neutralize or enhance sound waves, thereby making the indoor environment quieter or allowing sound to penetrate the wall better. This application can achieve sound adjustment through external sound adjustment means, eliminating the need for users to wear headphones for extended periods, not affecting users' daily activities, making it more convenient to use, and it does not emit sound waves directly to the ears, thus not affecting the user's ear health.

[0063] Specifically, the sound sensor 32 has its receiving hole facing the cavity of the outer shell. The sound sensor 32 sends the spectrum Pn, amplitude Dn, and second time Tn of the sound information to the controller 4. The vibration sensor 31 sends the spectrum Pm, amplitude Dm, and first time Tm of the vibration information to the controller 4. The controller 4 obtains the sound information and vibration information where the difference between Pn and Pm is within a preset difference range, calculates the difference between Tn and Tm of the sound information and the difference between Dn and Dm of the vibration information, and determines the sound wave source of the sound information and vibration information. The sound wave source is indoor sound wave or outdoor sound wave. The controller 4 controls the first adjustment component 2 to generate vibration and controls the second adjustment component 3 to emit sound waves to adjust the sound source according to the adjustment mode.

[0064] Understandably, comparing the spectrum Pm of vibration information and the spectrum Pn of sound information, if they are obtained from the same sound wave, then Pm and Pn should be the same. Considering the loss during sound transmission and the error during acquisition, when the difference between the two is set within a preset range, it is determined that they are obtained from the same sound wave. At this time, comparing Tm and Tn, based on the time when the vibration sensor 31 and the sound sensor 32 acquire the sound wave, the direction of sound wave transmission is determined. Sound waves propagating from indoors to outdoors are indoor sound waves, and sound waves propagating from outdoors to indoors are outdoor sound waves. At the same time, comparing the amplitude of vibration information and the amplitude of sound information, vibration will be lost during propagation. Therefore, the position of the sound wave received later will have a smaller amplitude. Therefore, by comparing the amplitude, the direction of sound wave propagation can also be determined. Thus, by comparing Tm and Tn and Dm and Dn simultaneously, the accuracy of determining the source of sound and vibration information is improved, resulting in better effects when making targeted sound adjustments.

[0065] In one embodiment, the first adjustment component 2 includes an oscillator 21, which is electrically connected to the controller 4 and used to generate vibration; the second adjustment component 3 also includes a sound-generating structure 33, a vibration sensor 31 located on the side of the housing 12 that contacts the wall and used to detect the vibration of the wall to obtain vibration information, a sound sensor 32 located near the oscillator 21 and used to obtain sound information, and the sound-generating structure 33 used to emit sound waves that are opposite to or the same phase as the sound wave source.

[0066] Vibration sensor 31 is located on the side of housing 12 that contacts the wall, allowing it to directly sense the wall's vibration and obtain more accurate vibration information. Vibrator 21 generates vibrations of opposite or same phase to the wall to neutralize or amplify the wall's vibration, thus achieving noise reduction and transparency functions. Sound sensor 32 is positioned close to vibrator 21, enabling precise detection of sound signals passing through it, improving detection accuracy and resulting in better noise neutralization during noise reduction. Sound sensor 32 can be a microphone from the prior art, and sound-generating structure 33 can be a speaker or horn from the prior art.

[0067] In one embodiment, the outer casing 12 includes a connecting portion 122 and a spacer portion 123. The connecting portion 122 is connected to the wall, and the spacer portion 123 is connected to the connecting portion 122 and spaced apart from the wall to form a mounting cavity 13 with one side open. A vibration sensor 31 is disposed in the connecting portion 122, and a sound sensor 32 is disposed in the spacer portion 123. The outer casing 12 is connected to the wall only by the connecting portion 122, with the other side spaced apart from the wall to form an opening. This reduces the impact of wall vibrations transmitted to the outer casing 12 on the sound sensor 32 in the spacer portion 123. The sound sensor 32 is preferably disposed at the end of the spacer portion 123 away from the connecting portion 122 to minimize the impact of wall vibrations. Furthermore, this facilitates the installation of the inner casing 11 and reduces assembly difficulty.

[0068] In one embodiment, the second adjustment component 3 further includes a second magnetic attractor disposed in the spacer portion 123, and the first adjustment component 2 further includes a first magnetic attractor 22 disposed corresponding to the second magnetic attractor. The second magnetic attractor can attract or de-attract with the first magnetic attractor 22 to attach or separate the spacer portion 123 and the inner shell 11 accordingly.

[0069] The second magnetic component is an electromagnet, and a switch can be set on the outer casing 12 to control the magnetic direction of the second magnetic component, thereby adjusting whether the second magnetic component generates an attractive force or a repulsive force on the first magnetic component 22. Specifically, the magnetic direction of the second magnetic component can be adjusted by changing the direction of the current. When not in use, the second magnetic component generates an attractive force on the first magnetic component 22, making the outer casing 12 and the inner casing 11 press tightly together, preventing dust and other particles from entering the gap 14 between the outer casing 12 and the inner casing 11. When in use, the vibrator 21 inside the inner casing 11 vibrates, at which time the second magnetic component generates a repulsive force on the first magnetic component 22, causing the outer casing 12 and the inner casing 11 to separate, preventing the vibration emitted by the vibrator 21 from causing the outer casing 12 to vibrate and affecting the sound sensor 32 and the vibration sensor 31, thereby improving the noise reduction effect and the transparency effect.

[0070] Please combine Figure 1 and Figure 2The present invention also proposes a sound adjustment method applied to a sound adjustment device 100. The sound adjustment device 100 includes a housing 1, a first adjustment component 2, a second adjustment component 3, and a controller 4. The housing 1 includes an inner shell 11 and an outer shell 12. The outer shell 12 is disposed in a wall and forms a mounting cavity 13 with the wall. The inner shell 11 is housed in the mounting cavity 13 and disposed in the wall. A gap 14 is formed between the inner shell 11 and the outer shell 12. A sound outlet 121 is opened at the end of the outer shell 12 away from the inner shell 11. The first adjustment component 2 is installed in the inner shell 11. The second adjustment component 3 is installed in the outer shell 12. The second adjustment component 3 includes a vibration sensor 31 and a sound sensor 32, which are spaced apart. Both the first adjustment component 2 and the second adjustment component 3 are electrically connected to the controller 4.

[0071] The sound adjustment method includes the following steps:

[0072] S100: Vibration information is obtained through the vibration sensor and the first moment of obtaining the vibration information is recorded; sound information is obtained through the sound sensor and the second moment of obtaining the sound information is recorded, wherein the first moment and the second moment are different.

[0073] The vibration sensor 31 can acquire the vibrations generated when sound propagates to its location. One type is the vibration generated at the wall when external sound passes through it, and the other type is the vibration generated at the vibration sensor 31 when indoor sound propagates outward. The sound sensor acquires sound information in the same way. That is to say, the vibration sensor 31 and the sound sensor can acquire more than one vibration or sound information. Therefore, the first moment when each vibration information is acquired for the first time and the second moment when each sound information is acquired for the first time are recorded, so as to accurately determine the moment when the sound propagating from indoors to outdoors and the sound propagating from outdoors to indoors are acquired.

[0074] S200: The controller determines the sound wave source of the sound information and the vibration information based on the vibration information and the first moment, as well as the sound information and the second moment, wherein the sound wave source is indoor sound wave or outdoor sound wave;

[0075] The controller 4 determines the direction of sound wave propagation based on the specific parameters of the vibration information and the first moment when the vibration information is first collected, and the specific parameters of the sound information and the second moment when the sound information is first collected, thereby determining the source of the sound wave. That is, the sound wave propagating from indoors to outdoors is an indoor sound wave, and the sound wave propagating from outdoors to indoors is an outdoor sound wave.

[0076] S300: The controller controls the first adjustment component to vibrate and the second adjustment component to emit sound waves according to the adjustment mode. The adjustment mode can be indoor noise reduction, outdoor noise reduction, indoor transparency, outdoor transparency, etc. According to the specific adjustment mode, indoor sound waves or outdoor sound waves are selected, and then the first adjustment component 2 vibrates and the second adjustment component 3 emits sound waves to perform sound adjustment operations such as noise reduction or enhancement.

[0077] The technical solution of this invention acquires vibration information through a vibration sensor 31 and records the first moment when the vibration information is acquired. Then, it acquires sound information through a sound sensor 32 and records the second moment when the sound information is acquired. It is understood that sound transmission takes time. Therefore, the vibration sensor 31 and the sound sensor 32, which are set at intervals, acquire the same sound wave in a sequential order. Therefore, by comparing the first moment and the second moment, it is determined whether the sound sensor 32 or the vibration sensor 31 acquired the sound wave first, thereby determining whether the sound wave came from indoors or outdoors. Then, the controller 4 controls the first adjustment component 2 to generate vibration and controls the second adjustment component 3 to emit sound waves for sound adjustment based on the vibration information and sound information. Specifically, it can generate vibrations with the same phase and emit sound waves with the same phase for enhancement, or generate vibrations with opposite phases and emit sound waves with opposite phases for noise reduction. This application uses an inner shell 11 and a first noise reduction component installed in the wall to vibrate and cancel or enhance sound waves, and a second noise reduction component to emit sound waves to neutralize or enhance sound waves, thereby making the indoor environment quieter or allowing sound to penetrate the wall better. This application can achieve sound adjustment through external sound adjustment means, eliminating the need for users to wear headphones for extended periods, not affecting users' daily activities, making it more convenient to use, and it does not emit sound waves directly to the ears, thus not affecting the user's ear health.

[0078] Please see Figure 3 In one embodiment, the vibration sensor 31 is disposed close to the wall, and the sound sensor 32 is disposed away from the vibration sensor 31 along the thickness direction of the wall.

[0079] Step S200 includes:

[0080] S210a: The controller compares the first time Tm and the second time Tn;

[0081] As mentioned earlier, sound propagation takes time, and the first moment Tm and the second moment Tn when the sound sensor 32 and the vibration sensor 31 collect the same sound wave will not be the same. Therefore, Tm and Tn are compared.

[0082] S220a: If Tm is greater than Tn, then the sound wave source of the sound information and the vibration information is determined to be indoor sound wave;

[0083] Understandably, the smaller the time, the earlier the sound wave is received. If Tm is greater than Tn, it means that the sound wave passes through the sound sensor 32 first and then the vibration sensor 31. The vibration sensor 31 is close to the wall, while the sound sensor 32 is far from the wall. In other words, the sound wave is propagating from indoors to outdoors, and the source of the sound wave is indoor sound wave.

[0084] S230a: If Tm is less than Tn, then the sound wave source of the sound information and the vibration information is determined to be outdoor sound wave.

[0085] Conversely, if Tm is greater than Tn, it means that the sound wave passes through the vibration sensor 31 first and then the sound sensor 32. The vibration sensor 31 is close to the wall, while the sound sensor 32 is far from the wall. This means that the sound wave is propagating from the outside to the inside, and the source of the sound wave is the outdoor sound wave. By comparing the first moment when the vibration information is first detected and the second moment when the sound information is first detected, the direction of sound propagation and the source of the sound wave can be determined, thereby separating the indoor sound wave and the outdoor sound wave. This facilitates subsequent individual adjustment of the indoor sound wave and the outdoor sound wave, improving the effect of sound adjustment.

[0086] Please see Figure 4 In another embodiment, the vibration sensor 31 is disposed close to the wall, and the sound sensor 32 is disposed away from the vibration sensor 31 along the thickness direction of the wall.

[0087] Step S100 includes:

[0088] S110: Obtain the vibration information spectrum Pm, amplitude Dm, and first time Tm through the vibration sensor; obtain the sound information spectrum Pn, amplitude Dn, and second time Tn through the sound sensor;

[0089] The system collects the spectrum Pm, amplitude Dm, and corresponding first time Tm of vibration information, as well as the spectrum Pn, amplitude Dn, and corresponding second time Tn of sound information. Understandably, in practical applications, it is rare to find only a single type of sound wave. In most cases, sound waves are quite complex, and there are multiple sets of vibration and sound information. Therefore, by collecting the spectrum and comparing it with the spectrum of sound information, the system can determine the correspondence between sound and vibration information, avoiding the need to pair sound information with vibration information generated by another sound wave, thus improving the accuracy of detection.

[0090] Step S200 includes:

[0091] S210b: The controller selects the vibration information and the sound information whose difference between Pm and Pn is within a preset difference range as the current vibration information and the current sound information, respectively.

[0092] If both are acquired from the same sound wave, then Pm and Pn should be the same. Considering the loss during sound transmission and the error during acquisition, when the difference between the two is set within a preset range, it is determined that they are acquired from the same sound wave and used as the current vibration information and the current sound information.

[0093] S220b: The controller compares the first moment Tm and amplitude Dm of the current vibration information with the second moment Tn and amplitude Dn of the current sound information;

[0094] S230b: If Tm is greater than Tn and Dm is less than or equal to Dn, then the sound wave source of the current sound information and the current vibration information is determined to be the indoor sound wave;

[0095] S240b: If Tm is less than Tn and Dm is greater than Dn, then the sound wave source of the current sound information and the current vibration information is determined to be the outdoor sound wave.

[0096] By comparing Tm and Tn of the two sensors, and based on the time it takes for the sound waves to be collected by the vibration sensor 31 and the sound sensor 32, the direction of sound wave propagation is determined. Sound waves propagating from indoors to outdoors are indoor sound waves, and sound waves propagating from outdoors to indoors are outdoor sound waves. At the same time, the amplitude of the vibration information and the amplitude of the sound information are compared. Vibration is attenuated during propagation, so the amplitude of the sound wave received later is smaller. Therefore, the direction of sound wave propagation can also be determined by comparing the amplitude. Thus, by comparing Tm and Tn as well as Dm and Dn simultaneously, the accuracy of determining the source of sound and vibration information is improved, resulting in better effects when making targeted sound adjustments.

[0097] Please see Figure 5 In one embodiment, the first adjustment component 2 includes an oscillator 21, and the second adjustment component further includes a sound-generating structure 33;

[0098] Step S300 includes:

[0099] S310: When the adjustment mode is indoor noise reduction mode, indoor sound waves are filtered out, the controller controls the vibrator to generate vibrations opposite to the phase of the indoor sound waves, and controls the sound-emitting structure to emit sound waves opposite to the phase of the indoor sound waves.

[0100] When it is necessary to prevent indoor sound from propagating to the outside, when the indoor noise reduction mode is turned on, the controller 4 filters out indoor sound waves and controls the vibrator 21 to generate vibrations opposite to the phase of the indoor sound waves. The sound-emitting structure 33 emits sound waves opposite to the phase of the indoor sound waves, thereby canceling and neutralizing the indoor sound waves, reducing the intensity of indoor sound waves propagating outward, and thus achieving the effect of indoor noise reduction.

[0101] S320: When the adjustment mode is outdoor noise reduction mode, outdoor sound waves are filtered out, the controller controls the vibrator to generate vibrations opposite to the phase of the outdoor sound waves, and controls the sound-emitting structure to emit sound waves opposite to the phase of the outdoor sound waves.

[0102] Conversely, when it is necessary to prevent outdoor sound from propagating into the room, when the outdoor noise reduction mode is activated, the controller 4 filters out outdoor sound waves and controls the vibrator 21 to generate vibrations opposite in phase to the outdoor sound waves. The sound-emitting structure 33 emits sound waves opposite in phase to the outdoor sound waves, thereby canceling and neutralizing the outdoor sound waves and reducing the intensity of the outdoor sound waves propagating inward, thus achieving the effect of outdoor noise reduction. By adjusting the mode, indoor and outdoor sound waves can be flexibly reduced, improving applicability and flexibility.

[0103] Please see Figure 6 Furthermore, step S300 also includes:

[0104] S330: When the adjustment mode is indoor transparency mode, indoor sound waves are filtered out, the controller controls the vibrator to generate vibrations with the same phase as the indoor sound waves to emit a first compensation sound wave, and controls the sound-emitting structure to emit a sound wave with the opposite phase to the first compensation sound wave.

[0105] When the indoor transparency mode is activated, the indoor sound waves need to be propagated to the outside. However, the sound absorption effect of the wall makes the sound wave transmission effect insufficient. Therefore, the controller 4 filters out the indoor sound waves and controls the vibrator 21 to generate vibration with the same phase as the indoor sound waves to emit a first compensation sound wave, which enhances the indoor sound waves and improves their effect of propagating outward through the wall. The sound-emitting structure 33 emits a sound wave with the opposite phase to the first compensation sound wave to cancel the sound waves propagating into the room generated by the vibration of the vibrator 21, thereby avoiding the generation of echoes and noise in the room.

[0106] S340: When the adjustment mode is outdoor transparent mode, outdoor sound waves are filtered out, and the controller controls the vibrator to generate vibrations with the same phase as the outdoor sound waves to emit a second compensation sound wave.

[0107] Conversely, when the outdoor transparent mode is activated, it is necessary to transmit outdoor sound waves into the room. However, the sound absorption effect of the wall makes the transmission effect of the sound waves insufficient. Therefore, the controller 4 filters out the outdoor sound waves and controls the vibrator 21 to generate vibrations with the same phase as the outdoor sound waves to emit a second compensation sound wave, which enhances the indoor sound waves and improves their effect of propagating outward through the wall. At this time, the sound waves generated by the vibrator 21 need to propagate into the room to enhance the outdoor sound waves. At this time, the sound-emitting structure 33 does not need to emit sound waves to cancel the second compensation sound wave.

[0108] S350: When the adjustment mode is the full transparency mode, indoor sound waves and outdoor sound waves are simultaneously filtered out. The controller controls the vibrator to generate vibrations with the same phase as the indoor sound waves to emit a first compensation sound wave, and controls the vibrator to generate vibrations with the same phase as the outdoor sound waves to emit a second compensation sound wave.

[0109] When it is necessary to transmit outdoor sound waves into the room while simultaneously transmitting indoor sound waves outwards, the full transparency mode is activated. In this mode, the first and second compensation sound waves are emitted at the same time, thereby simultaneously enhancing both indoor and outdoor sound waves. Through the flexible application of multiple transparency modes, the flexibility and applicability of sound adjustment methods are improved.
