Description

Technical Field

[0001] This application relates to the field of intelligent vehicles, specifically to a seat headrest device and its control method and control device. Background Technology

[0002] With the development of intelligent vehicles, vehicle users are increasingly valuing the comfort and experience of the in-car cabin. More users are accustomed to enjoying audio entertainment functions while driving and are pursuing better sound effects and a dedicated playback space. Traditional in-car audio systems mostly install speakers in the doors and center console, making the optimal listening position in the cabin relatively fixed. The sound effect from other positions often fails to meet the user's listening needs. Some in-car audio systems also install speakers inside the seat headrests, where the speaker outlets are blocked by the user's head, resulting in significant sound leakage. This also fails to achieve good sound effects and meet the user's need for a private listening experience.

[0003] Therefore, how to improve the listening experience and meet the diverse listening needs of users has become an urgent problem to be solved in the industry. Summary of the Invention

[0004] To improve the listening experience and meet the diverse listening needs of users, this application provides a seat headrest device, a control method, and a control device.

[0005] A first aspect of this application provides a seat headrest device, comprising: a headrest portion; a first side wing movably connected to the headrest portion; a second side wing movably connected to the first side wing; and a first speaker module mounted on the second side wing.

[0006] With the above configuration, the first and second side wings can be moved to different positions, allowing their positions to be adjusted according to the user's head position. This, in turn, allows the first speaker to be adjusted according to the user's ear position, preventing the first speaker module from being blocked by the passenger's head and meeting the personalized needs of different users. When the user does not need to listen to music, the first side wing can be moved to the headrest side, and the second side wing can be retracted relative to the first side wing, preventing the side wings from colliding with the user's head and saving cabin space.

[0007] In one possible implementation, a second speaker module is also included, which is mounted on the first side wing.

[0008] The above settings expand the sound output range, achieving a surround sound effect and meeting more of the passengers' listening needs.

[0009] In one possible implementation, the first speaker module is movably connected to the second wing.

[0010] With the above settings, the first speaker module can be moved to different positions, thereby achieving different sound output effects and meeting the listening needs of different passengers.

[0011] In one possible implementation, the first side wing is rotatably connected to the headrest, and the second side wing is rotatably connected to the first side wing.

[0012] The above settings provide a greater range of motion for the first and second side wings, resulting in a wider variety of sound output effects.

[0013] In one possible implementation, the first side wing is slidably connected to the headrest, and the second side wing is rotatably connected to the first side wing.

[0014] With the above configuration, when the first side wing slides out relative to the headrest, there is no need to leave room for the first side wing to move around the headrest, saving cabin space and allowing the seat headrest device to adapt to different vehicle models; the second side wing is rotatably connected relative to the first side wing, allowing the first speaker to be adjusted according to the position of the user's ear, avoiding the speaker being blocked by the user's head, meeting the personalized needs of different users, and ensuring that the user can enjoy audio exclusively.

[0015] In one possible implementation, the first side wing is rotatably connected to the headrest, and the second side wing is slidably connected to the first side wing.

[0016] In one possible implementation, the first side wing is slidably connected to the headrest, and the second side wing is slidably connected to the first side wing.

[0017] In one possible implementation, the first wing includes a first housing for accommodating the second wing.

[0018] With the above configuration, when the user does not need to listen to audio, the second wing can be housed in the first shell of the first wing, further saving cabin space.

[0019] In one possible implementation, the seat headrest device further includes: a first drive mechanism for driving the movement of a first side wing; and a second drive mechanism for driving the movement of a second side wing.

[0020] The above settings enable automated movement of the first and second flanks, improving the user experience.

[0021] In one possible implementation, the seat headrest device further includes a third drive mechanism, and the first speaker module includes multiple speakers, with the third drive mechanism used to drive the multiple speakers to move.

[0022] The above settings enable automated movement of the first speaker module, enhancing the user experience.

[0023] A second aspect of this application provides a control method for a seat headrest device, comprising: acquiring a first characteristic position of a seat occupant, the occupant corresponding to the seat headrest device; and controlling the movement of a first side wing and a second side wing according to the first characteristic position, such that a first speaker module is directed toward the first characteristic position, wherein the seat headrest device comprises: a first side wing movably connected to a headrest portion, a second side wing movably connected to the first side wing, and a first speaker module mounted on the second side wing.

[0024] With the above settings, the first speaker can be automatically moved to the first special position, preventing the sound outlet of the first speaker module from pointing to other positions, reducing sound leakage of the first speaker module, satisfying the user's exclusive audio needs, and improving the user's listening experience.

[0025] In one possible implementation, when the first speaker module is oriented toward the first feature position, the angle between the line connecting the first speaker module and the first feature position and the line connecting the two first feature positions is less than a preset angle.

[0026] The above settings further prevent sound leakage from the first speaker module, meet the user's need for exclusive listening, and enhance the user's listening experience.

[0027] In one possible implementation, the method further includes: controlling the movement of the first and second wings according to the second wing position set by the user, so that the second wing moves to the second wing position.

[0028] The above settings allow the positions of the first and second side wings to be adjusted according to user needs, satisfying personalized requirements and enhancing the user experience.

[0029] In one possible implementation, the control method further includes: controlling the movement of the speaker according to a listening mode, including: a private mode, a surround mode, or a personalized mode, wherein the first speaker module is movably connected to the second side wing, and the first speaker module includes: multiple speakers.

[0030] By setting the first speaker to different positions on the second side wing, different audio effects are achieved, meeting different listening needs of users and enhancing the user experience.

[0031] In one possible implementation, when the listening mode is the private mode, multiple speakers are located in the center of the second side wing.

[0032] The above settings concentrate the speaker's sound output as much as possible, allowing users to enjoy audio exclusively.

[0033] In one possible implementation, when the listening mode is a private mode, the second speaker module is muted and the first speaker module emits sound, wherein the second speaker module is mounted on the first side wing.

[0034] When a passenger selects the private mode, the second speaker is muted while the first speaker is audible, preventing other passengers from hearing the sound from the second speaker, thus satisfying their need for privacy and enhancing the user experience.

[0035] In one possible implementation, the movement includes: driving the movement of the first wing via a first drive mechanism; and driving the movement of the second wing via a second drive mechanism.

[0036] In one possible implementation, the movement includes: driving the movement of multiple speakers via a third drive mechanism.

[0037] A third aspect of this application provides an apparatus for controlling a seat headrest device, comprising an acquisition module for acquiring a first characteristic position of an occupant, wherein the occupant corresponds to the seat headrest device; and a control module for controlling the movement of a first side wing and a second side wing according to the first characteristic position, such that a first speaker module is oriented toward the first characteristic position; wherein the first side wing is movably connected to the headrest portion, the first side wing is movably connected to the second side wing, and the first speaker module is mounted on the second side wing.

[0038] In one possible implementation, when the first speaker module is oriented toward the first feature position, the angle between the line connecting the first speaker module and the first feature position and the line connecting the two first feature positions is less than a preset angle.

[0039] In one possible implementation, the control module is further configured to: control the movement of the first wing and the second wing according to the preset second wing position, so that the second wing moves to the second wing position.

[0040] In one possible implementation, the control module is further configured to: control the movement of multiple speakers according to a listening mode, the listening mode including: a private mode, a surround mode, or a personalized mode, wherein a first speaker module is movably connected to a second side wing, and the first speaker module includes: multiple speakers.

[0041] In one possible implementation, when the listening mode is the private mode, multiple speakers are located in the center of the second side wing.

[0042] In one possible implementation, the control module is also used to: control the first speaker module to emit sound and control the second speaker module to mute when the listening mode is a private mode, wherein the second speaker module is mounted on the first side wing.

[0043] In one possible implementation, the control module is specifically used to: drive the movement of the first wing through the first drive mechanism; and drive the movement of the second wing through the second drive mechanism.

[0044] In one possible implementation, the control module is specifically used to drive the movement of multiple speakers via a third drive mechanism.

[0045] A fourth aspect of this application provides a seat, including: a headrest device provided in the first aspect of this application and any possible implementation thereof.

[0046] A fifth aspect of this application provides a vehicle comprising: a seat headrest device provided in the first aspect of this application and any possible implementation thereof.

Therefore, it should be interpreted as specifying the presence of the mentioned feature, integral, step, or component, but does not exclude the presence or addition of one or more other features, integrals, steps, or components, or groups thereof.

[0067] The term "an embodiment" or "an embodiment" as used in this specification means that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in at least one embodiment of the invention. Therefore, the terms "in one embodiment" or "in an embodiment" appearing throughout this specification do not necessarily refer to the same embodiment, but may refer to the same embodiment. Furthermore, in one or more embodiments, the particular features, structures, or characteristics can be combined in any suitable manner, as will be apparent to those skilled in the art from this disclosure.

[0068] Figure 1 This illustrates an arrangement of speaker modules in an in-vehicle audio system, such as... Figure 1 As shown, speaker module 01 is located in the car doors, center console, and behind the rear seats. When playing audio, with all speaker modules emitting sound, the optimal listening position is relatively fixed, and the listening effect in other positions is poor, failing to meet the user's listening needs. Secondly, the speaker modules' sound output is directed at all occupants, failing to meet the personalized needs of individual occupants. For example, when making calls through the in-vehicle audio system, it is difficult to guarantee the need for individual conversations.

[0069] Figure 2 This illustrates another arrangement of speaker modules in an in-vehicle audio system, such as... Figure 2 As shown, the headrest has side wings 02 extending outwards on both sides, and the speaker module is arranged on the side wings 02. However, these side wings 02 are usually not adjustable, and the range of motion of the occupant's head is limited. This means that when the occupant is sitting, in order to ensure that the ear position is close to the sound outlet of the speaker module, the occupant's head needs to be pressed tightly against the headrest, which reduces the occupant's comfort. Since different occupants have different heights and head positions, the sound outlet of the speaker module cannot be adapted to all occupants, and sound leakage will still occur.

[0070] In order to improve the listening effect, reduce sound leakage and meet the diverse listening needs of users, embodiments of this application provide a seat headrest device and its control method.

[0071] Figures 3-6This illustration shows an application scenario for the seat headrest device provided in this application embodiment. The seat headrest device provided in this application embodiment can be applied to car seats, train, bullet train, high-speed rail seats, airplane seats, and home or commercial massage chairs.

[0072] like Figure 3 As shown, the seat headrest device 10 provided in this application embodiment can be applied to the seats of high-speed trains. When passengers need to enjoy audio entertainment functions, the side wings 2 and 3 can be controlled to switch from a retracted state relative to the headrest of the seat (as shown in seat 20B) to an extended state (as shown in seat 20A). The side wings 2 and 3 in the extended state are located on both sides of the passenger's head and can be adjusted according to the position of the passenger's head, so that the speaker modules in the side wings can face the passenger's ears, reduce the sound leakage of the speakers, and avoid affecting the rest of other passengers in the public transportation environment.

[0073] like Figure 4 As shown, the seat headrest device 10 provided in this application embodiment can also be applied to aircraft seats, and... Figure 3 The scenario illustrated is similar. When passengers need to enjoy audio entertainment functions, they can control the side wings 2 and 3 to switch from a retracted state relative to the headrest of the seat (as shown in seat 20C) to an extended state (as shown in seat 20D). In the extended state, the side wings 2 and 3 are located on both sides of the passenger's head and can be adjusted according to the passenger's head position so that the speaker modules inside the side wings are facing the passenger's ears, reducing sound leakage from the speakers and avoiding affecting the rest of other passengers in the public transportation environment.

[0074] like Figure 5 As shown, the headrest device 10 provided in this embodiment can also be applied to a massage chair, and... Figure 3 The scenario illustrated is similar. When a user needs to enjoy audio entertainment functions, they can control the side wings 2 and 3 to switch from a retracted state relative to the headrest of the seat to an extended state. In the extended state, the side wings 2 and 3 are located on both sides of the user's head and can be adjusted according to the occupant's head position so that the speaker modules inside the side wings are facing the user's ears, reducing sound leakage from the speakers and avoiding disturbing other users' rest.

[0075] like Figure 6 As shown, the headrest device 10 provided in this application embodiment can also be applied to vehicle seats. When the occupant needs to enjoy audio entertainment functions, the side wings 2 and 3 can be controlled to switch from a folded state relative to the headrest of the seat to an extended state. The side wings 2 and 3 in the extended state are located on both sides of the occupant's head and can be adjusted according to the occupant's head position or the occupant's needs, thereby meeting the occupant's different listening needs.

[0076] Example 1: Seat headrest device

[0077] Figure 7 A schematic diagram of a specific embodiment of the seat headrest device provided in this application is shown, as follows: Figure 7 As shown, the seat headrest device 10 (hereinafter also referred to as the headrest device) is installed on the seat back 20. Of course, the headrest device 10 can also be integrally connected to or integrally formed with the seat back 20, and this application does not limit this. The headrest device 10 includes: a headrest part 1, a first side wing 2 rotatably connected to the headrest part 1, a second side wing 3 rotatably connected to the first side wing 2, a first speaker module 41 installed on the second side wing 3, and a second speaker module 42 installed on the first side wing 2.

[0078] like Figure 8 As shown, the headrest portion 1 includes: a headrest 11 and a first rotating shaft connecting portion 12 extending outward from both sides of the headrest 11, the first rotating shaft connecting portion 12 being used to connect with the first side wing 2. The first side wing 2 includes: a first housing 21, a first rotating shaft 22, and a second rotating shaft connecting portion 23 (as shown in the image). Figure 9 As shown, Figure 8 (Not shown), the first housing 21 has a side connected to the headrest 11 and a side away from the headrest 11. A first rotating shaft 22 is disposed on the side of the first housing 21 connected to the headrest 11, and a second rotating shaft connecting part 23 is disposed on the side of the first housing 21 away from the headrest 11. The first rotating shaft 22 can be inserted into the first rotating shaft connecting part 12, thereby rotating relative to the first rotating shaft connecting part 12, so that the first side wing 2 can rotate relative to the headrest 11. Figure 9 As shown, the second side wing 3 includes a second housing 31 and a second rotating shaft 32. The second housing 31 has a side connected to the first side wing 2 and an opposite side to the side connected to the first side wing 2. The second rotating shaft 32 is disposed on the side of the second housing 31 connected to the first side wing 2. The second rotating shaft 32 can be inserted into the second rotating shaft connecting part 23, thereby being able to rotate relative to the second rotating shaft connecting part 23, so that the second side wing 3 can rotate relative to the first side wing 2.

[0079] like Figure 7 As shown, the first housing 21 has a side facing the occupant and a side opposite to the occupant-facing side, and the second speaker module 42 is mounted on the occupant-facing side of the first housing 21; the second housing 31 has a side facing the occupant and a side opposite to the occupant-facing side, and the first speaker module 41 is mounted on the occupant-facing side of the second housing 31. The first speaker module 41 includes a plurality of first speakers 411 ( Figure 7The diagram schematically shows four speakers and a first speaker slide 412. The first speaker slide 412 is installed in the second housing 31, and the first speaker 411 is installed in the first speaker slide 412 and can slide in the first speaker slide 412. The second speaker module 42 includes a plurality of second speakers 421 (…). Figure 7 Four speakers are schematically shown in the diagram, and a second speaker slide 422 is installed in the first housing 21. The second speaker 421 is installed in the second speaker slide 422 and can slide in the second speaker slide 422.

[0080] like Figure 8 As shown, when the occupant does not need to use the sound playback function of the headrest device, the first side wing 2 and the second side wing 3 can be rotated to the side of the headrest 11 that does not contact the occupant's head. Figure 10 As shown, when occupant P needs to use the seat headrest device, the first side wing 2 and the second side wing 3 can be rotated to both sides of occupant P's head, and the rotation angle of the first side wing 2 and the second side wing 3 can be adjusted according to the position of the occupant's ears, as well as the first speaker 411 and the second speaker 421 can be adjusted in the first speaker slide 412 and the second speaker slide ( Figure 10 The location (not shown in the image) satisfies the different listening needs of passenger P.

[0081] like Figure 11 As shown, the seat headrest device also includes a side wing drive mechanism 50, which is used to drive the first side wing or the second side wing. The side wing drive mechanism 50 includes: a motor 501, a motor gear 502 connected to the output shaft of the motor 501, and a rotating shaft gear 503 meshing with the motor gear 502. The rotating shaft gear 503 can be mounted on the first rotating shaft 22 or the second rotating shaft 32. When the motor 501 is started, the motor output shaft drives the motor gear 502 to rotate, thereby driving the rotating shaft gear 503 to drive the first rotating shaft 22 or the second rotating shaft 32 to rotate, and thus driving the first side wing or the second side wing to rotate.

[0082] In some embodiments, the headrest device may further include a speaker drive mechanism for driving the movement of the speaker in the speaker module. The speaker drive mechanism may be located in the side wing where the speaker module is mounted. The speaker drive mechanism may include: a motor, a crank mechanism connected to the output shaft of the motor, and a slider connected to the crank mechanism and located in a speaker slide (a first speaker slide or a second speaker slide). The slider is equipped with a speaker. When the motor is started, the output shaft of the motor drives the crank mechanism to rotate, thereby driving the slider to move the speaker in the slide.

[0083] In some embodiments, the movement of the first and second side wings can be driven by only one drive mechanism. For example, a transmission member can be provided between the first rotating shaft 22 and the second rotating shaft 32. The transmission member is used to connect the motor gear 502 and the rotating shaft gear 503 mounted on the second rotating shaft 32. By making the motor gear 502 mesh with the rotating shaft gear 503 mounted on the first rotating shaft 22 and the transmission member respectively, the movement of the first side wing 2 and the second side wing 3 can be controlled.

[0084] Example 2: Seat headrest device

[0085] Figure 12 This illustration shows a structural schematic diagram of another specific embodiment of the seat headrest device provided in this application, which is consistent with... Figure 7 The difference in the illustrated headrest device is that, in this embodiment, the first side wing 12 is slidably connected to the headrest portion 101, the second side wing 13 can be accommodated in the first housing 121 of the first side wing 12, and a third speaker module 141 is mounted on the second side wing 13.

The seat headrest device 110 is mounted on the seat back 120. Of course, the headrest device 110 can also be integrally connected to the seat back 120, and this application does not limit this.

[0087] like Figure 12 As shown, the headrest portion 101 includes: a headrest 111 and first slide rails 112 disposed on both sides of the headrest 111. The first side wing 12 includes: a first housing 121, a first slide rail 122 for slidably connecting with the first slide rail 112, a receiving portion 124 for accommodating the second side wing 13, and a second rotating shaft connecting portion 123 for rotatably connecting with the second side wing 13 (e.g., ...). Figure 13 As shown, Figure 12 (Not shown). The first housing 121 has a side facing the headrest 111 and a side facing away from the headrest 111. A first slide rail 122 is provided on the side of the first housing 121 facing the headrest 111, and a receiving portion 124 is provided on the side of the first housing 121 facing away from the headrest 111. The receiving portion 124 can be shaped to fit the second side wing 13, thereby allowing the second side wing 13 to be folded therein (e.g., ...). Figure 13 As shown), this saves space in the headrest device 110. Figure 13 As shown, a second rotating shaft connection portion 123 is provided on the occupant-facing side of the first housing 121 for rotatable connection with the second side wing 13. Figure 13As shown, the second side wing 13 includes: a second housing 131 and a second rotating shaft 132 mounted on one side of the second housing 131. The second rotating shaft 132 is inserted into the second rotating shaft connecting part 123, thereby enabling the second side wing 13 to rotate relative to the first side wing 12.

[0088] like Figure 13 As shown, the second housing 131 has a side facing the occupant and a side facing away from the occupant, as... Figure 12 As shown, the third speaker module 141 is mounted on the side of the second housing 131 facing the occupant, as... Figure 13 As shown, the third speaker module 141 includes a plurality of third speakers 1411 ( Figure 13 (4 are schematically drawn in the figure) and the third speaker slide 1412. The third speaker slide is installed in the second housing 131, and the third speaker 1411 is installed in the third speaker slide 1412 and can slide in the third speaker slide 1412.

[0089] like Figure 15 As shown, when passenger p needs to enjoy audio entertainment functions, they can follow arrow D (as shown in the image). Figure 14 Slide the first side wing 12 of the headrest device in the folded state in the direction shown, so that the first side wing 12 slides to both sides of the head, and then slides along arrow d (as shown). Figure 14 Rotate the second side wing 13 in the direction shown to bring it to the ear position. Finally, adjust the position of the third speaker 1411 in the third speaker slide 1412 according to your listening needs.

[0090] like Figure 16 As shown, the seat headrest device also includes a first side wing drive mechanism 150 for driving the first side wing 12. The first side wing drive mechanism 150 includes: a motor 1501, a motor gear 1502 connected to the output shaft of the motor 1501, and a transmission device 1503 meshing with the motor gear 1502. The transmission device 1503 can be fixedly connected to the first slide rail 122 of the first side wing through a connector. When the motor 1501 is started, the output shaft of the motor 1501 drives the motor gear 1502 to rotate, thereby driving the transmission device 1503 to move the connector, and then driving the first slide rail 122 of the first side wing 12 to slide along the first slide rail 112, thereby causing the first side wing 12 to slide to both sides of the occupant's head.

[0091] like Figure 11As shown, the seat headrest device also includes a second side wing drive mechanism for driving the second side wing 13. The structure of the second side wing drive mechanism is the same as that of the side wing drive mechanism 50 in Embodiment 1 of this application. It includes: a motor 501, a motor gear 502 connected to the output shaft of the motor 501, and a rotating shaft gear 503 meshing with the motor gear 502. The rotating shaft gear 503 can be mounted on the second rotating shaft 132. When the motor 501 is started, the motor output shaft drives the motor gear 502 to rotate, thereby driving the rotating shaft gear 503, and then driving the second side wing 13 to rotate to both sides of the occupant's head.

[0092] In some embodiments, the movement of the first and second side wings can be driven by only one drive mechanism. For example, a second motor gear can be provided on the output shaft of the motor, and a second transmission member can be provided between the second rotating shaft 32 and the second motor gear. The movement of the first side wing 12 and the second side wing 13 can be controlled by meshing the second motor gear with the second transmission member and by meshing the motor gear 1502 with the transmission device 1503.

[0093] In some embodiments, the headrest device may further include a speaker drive mechanism for driving the movement of the speaker in the speaker module. The speaker drive mechanism may be located in the side wing where the speaker module is mounted. The speaker drive mechanism may include: a motor, a crank mechanism connected to the output shaft of the motor, and a slider connected to the crank mechanism and located in a speaker slide (a first speaker slide or a second speaker slide). The slider is equipped with a speaker. When the motor is started, the output shaft of the motor drives the crank mechanism to rotate, thereby driving the slider to move the speaker in the slide.

[0094] Example 3: Seat headrest device

[0095] The seat headrest device provided in Embodiment 3 differs from the seat headrest devices provided in Embodiments 1 and 2 in that it further includes a third side wing, which can be rotatably or slidably connected to the first side wing or the second side wing in the manner described above.

[0096] In some embodiments, the third wing may include a third housing and a third rotational shaft disposed on one side of the third housing. Figure 7 In the illustrated seat headrest device, a third rotating shaft connecting part can be provided on the other side of the second side wing. The third rotating shaft of the third side wing is inserted into the third rotating shaft connecting part, thereby enabling the third side wing to rotate relative to the second side wing. The side wing drive mechanism 50 in Embodiment 1 and Embodiment 2 drives the third side wing in the same manner.

[0097] In some embodiments, there may be multiple third wings, and each third wing may be rotatably or slidably connected to the other wing in the manner described above, or any third wing may be rotatably or slidably connected to the second wing in the manner described above.

[0098] In some embodiments, a third speaker module may also be provided on the third side wing. The third speaker module is the same as the first and second speaker modules of the seat headrest device provided in Embodiment 1 and Embodiment 2, and will not be described again here for the sake of simplicity.

[0099] Example 4: Control method for seat headrest device

[0100] The control method for the seat headrest device in this embodiment can be executed by a terminal, such as a vehicle, or by an electronic device applied in the vehicle, such as an Electronic Control Unit (ECU), a system chip, or a general-purpose chip. The ECU can acquire and process data from sensors or cameras located in the vehicle, and output corresponding control signals to the drive mechanisms of the seat headrest device (first side wing drive mechanism, second side wing drive mechanism, and speaker drive mechanism), for example, controlling the rotation of the motor output shaft, thereby controlling the movement of the first and second side wings. It is understood that the control of the seat headrest device can be automatically implemented by in-vehicle electronic equipment based on preset conditions, or it can be implemented in response to user input. Typically, the user selects a preset control mode (e.g., exclusive mode or surround mode) or manually controls the first side wing, second side wing, and first and second speaker modules through physical buttons in the vehicle, a mobile terminal (e.g., a mobile phone with a vehicle control app), or the human-machine interface of the vehicle system.

[0101] Figure 17 A flowchart illustrating the control method of the seat headrest device provided in an embodiment of this application is shown, as follows: Figure 17 As shown, the control method for the seat headrest device includes the following steps:

[0102] Step S1: Obtain the first feature position of the occupant in the seat.

[0103] In this context, the seat occupant corresponds to the headrest device. When the seat occupant corresponds to the headrest device, it indicates that the occupant is sitting on the seat where the headrest device is installed. For example, the seat cushion may bear most of the occupant's body weight, such as more than 60% of the occupant's body weight; or a portion of the seat back may be in contact with the occupant, such as more than 40% of the seat back; or a portion of the headrest device may be in contact with the occupant, such as more than 30% of the headrest device; or the seatbelt may be fastened, etc.

[0104] The seat headrest device includes: a first side wing movably connected to the headrest portion, a second side wing movably connected to the first side wing, and a first speaker module installed on the second side wing; the first characteristic position includes the occupant's head, eyes, ears, etc.; the first characteristic position can be obtained by a camera in the cabin, such as an RGB camera or an infrared camera, or the first characteristic position can also be obtained by a detection sensor installed on the headrest, cabin side wall, or other positions, which is not limited in this application.

[0105] Step S2: Based on the first feature position, control the movement of the first side wing and the second side wing so that the first speaker module faces the first feature position.

[0106] The first speaker module includes a plurality of first speakers. In some embodiments, the first speaker module further includes a slide for sliding the speakers therein. When the first speaker module is oriented toward the first characteristic position, the angle between the sound output direction of each speaker in the first speaker module and the line connecting the speaker and the first characteristic position is less than a first angle.

[0107] In some embodiments, the movement of the first and second side wings can also be controlled in response to user operation, such as by the user pressing a control button located on the seat or by the user pressing a control button located in another location in the vehicle, thereby causing the first speaker module to face the first characteristic position. Alternatively, the user can rotate a rotary button located on the seat to adjust the degree of movement of the first and second side wings, thereby causing the first speaker module to face the first characteristic position.

[0108] In some embodiments, the system can also respond to user voice commands, such as the user issuing a voice command to "expand the headrest device side wings," to control the movement of the first and second side wings, causing the first speaker module to face the first feature position. The voice commands can be acquired via a microphone and recognized through voice recognition or other methods to obtain the user's intent and position, and then the movement of the first and second side wings can be controlled based on the user's intent and position.

[0109] In some embodiments, the device can also respond to operation commands issued by the user through an operating terminal (mobile phone, smartwatch, smart tablet, and remote control, etc.). For example, the user can input the unfolding angle, unfolding position, or manually control the movement of the simulated headrest side wings on the terminal's display screen to achieve movement control of the first and second side wings, so that the first speaker module faces the first feature position.

[0110] In some embodiments, the movement of the first and second side wings can also be controlled in response to a user's physical operation, such as the user manually moving the first side wing and the second side wing to their desired position or a first characteristic position, thereby enabling the first speaker module to face the first characteristic position.

[0111] In some embodiments, the first speaker module is located in a plane and is arranged in an axisymmetric or centrosymmetric manner. When the angle between the line connecting the center of the first speaker module and the first characteristic position and the normal line of the plane passing through the center of the speaker module is less than a first angle, the first speaker module is oriented toward the first characteristic position.

[0112] In some embodiments, the movement of the first side wing can be driven by a first driving mechanism; and the movement of the second side wing can be driven by a second driving mechanism. For a detailed description of the first and second driving mechanisms, please refer to the descriptions of the side wing driving mechanisms for driving the first and / or second side wing in Embodiments 1 and 2 of this application. For the sake of brevity, they will not be repeated here.

[0113] In some embodiments, when the first speaker module is oriented toward the first feature position, the orientation refers to the point on the plane where the first feature position is projected onto the first speaker module being located being within the region of the first speaker module.

[0114] In some embodiments, when the angle between the line connecting the first speaker module and the occupant's ear and the line connecting the two ears of the occupant is less than a preset angle, the sound output direction of the first speaker module can be directly facing the user's listening position, greatly reducing sound leakage and satisfying the user's exclusive audio enjoyment needs.

[0115] In some embodiments, the first wing and the second wing can be moved according to the second wing position set by the user, so that the second wing moves to the second wing position.

[0116] When the occupant's primary characteristic position cannot be obtained, or when the user wishes to adjust the position of the second side wing according to their own preferences, the position of the second side wing can be set according to the occupant's needs. For example, the position of the second side wing can be displayed on the vehicle's central control screen, and the position of the second side wing relative to the occupant can be controlled by operating the central control screen. This application does not limit this.

[0117] In some embodiments, when the first characteristic position of the occupant cannot be obtained, or when the user wishes to adjust the position of the second side wing according to their own preferences, the movement of the first side wing, the second side wing, and the speaker module can be achieved by physical buttons or physical rotary buttons located on the seat, vehicle system, or seat headrest.

[0118] Specifically, when a user presses the physical button, the first wing and / or the second wing can move to a specific position. Alternatively, the movement of the first wing and / or the second wing can be controlled by controlling the duration of the physical button press. For example, when a user presses the physical button, the first wing and / or the second wing can reciprocate within a preset range, and the physical button can be released when the first wing and / or the second wing reaches the user's desired position.

[0119] Specifically, when a user presses a physical button, the speaker in the speaker module can move to another specific position. Alternatively, the degree of movement of the speaker module can be controlled by controlling the duration of the physical button press. For example, when the physical button is pressed, the speaker in the speaker module will move back and forth within a preset range, and the button can be released when the speaker moves to the user's desired position.

[0120] Specifically, users can also control the degree of movement (expansion angle) of the first and / or second side wings by rotating the rotary button, or control the position of the speaker in the speaker module by rotating the rotary button.

[0121] In some embodiments, the control method further includes: controlling the movement of the speaker according to a listening mode, the listening mode including: surround mode, exclusive mode, or personalized mode, wherein in the exclusive mode, the first speaker is located at the center of the second side wing. In some embodiments, when the first speaker module is located in a plane and the first speakers are equidistant and arranged in a straight line, the directivity of the first speaker module can be expressed by the following formula: the greater the directivity, the less sound leakage, and the stronger the exclusivity.

[0122] ,

[0123] Where θ is the angle between the intersection of the normal to the plane containing the first speaker module and the line connecting the first feature position to the normal; k is the wavenumber of the first speaker, which increases with the frequency of the first speaker; N is the number of the first speakers; and d is the distance between two adjacent first speakers. Therefore, when the first speaker is located in the center of the first or second side wing, there is less sound leakage.

[0124] In some embodiments, in surround mode, the speaker can be located at the edge of the second side wing. When the user does not need exclusive audio, the speaker can be positioned at the edge of the second side wing.

[0125] In some embodiments, in personalized mode, users can set the speaker position according to their own needs and store the set speaker position in memory. When the system recognizes the user, it controls the speaker to move to the position set by the user.

[0126] In some embodiments, the movement of the plurality of speakers can be driven by a third driving mechanism. A detailed description of the third driving mechanism can be found in the descriptions of the speaker driving mechanism in Embodiments 1 and 2 of this application, and will not be repeated here for the sake of brevity.

[0127] In some embodiments, the second speaker module is mounted on the first side wing. When the listening mode is a private mode, the second speaker module is muted, and the first speaker module emits sound. When the occupant selects a private mode, the second speaker module can be muted, for example, by powering off the second speaker module; when the occupant selects a surround mode, both the first and second speaker modules can emit sound, thereby achieving multi-channel surround sound.
