Example four: control method of seat headrest device

The control method of the seat headrest device in the embodiment of the present application may be executed by a terminal, for example, a terminal such as a vehicle, or may be executed by an electronic device applied in the vehicle, for example: an Electronic Control Unit (ECU), a system chip, a general-purpose chip, and the like. The ECU may acquire and process data obtained by a sensor or a camera disposed on the vehicle, and output corresponding control signals to the driving mechanisms (the first wing driving mechanism, the second wing driving mechanism, and the speaker driving mechanism) of the seat headrest apparatus, for example, to control the degree of rotation of the output shaft of the motor, thereby controlling the movement of the first wing and the second wing. It is to be understood that the control of the seat headrest apparatus may be automatically implemented by the in-vehicle electronic device based on a preset condition, or may be implemented in response to an input from a user. Typically, a user selects a preset control mode (e.g., an exclusive mode or a surround mode) or manually controls the first wing, the second wing, the first speaker module and the second speaker module through physical keys in a vehicle, a mobile terminal (e.g., a mobile phone equipped with an App for controlling the vehicle), and a human-computer interface of a vehicle machine system.

Fig. 17 is a flowchart illustrating a control method of a seat headrest device according to an embodiment of the present application, and as illustrated in fig. 17, the control method of the seat headrest device includes the steps of:

step S1: a first characteristic position of an occupant of the seat is obtained.

Wherein the seat occupant corresponds to the seat headrest apparatus. When the seat occupant corresponds to the seat headrest apparatus, it is indicated that the occupant is seated on the seat to which the headrest apparatus is mounted. Illustratively, the cushion portion of the seat bears a majority of the weight of the occupant's body, e.g., bears more than 60% of the weight of the occupant's body; or a portion of the area of the seat back is in contact with the occupant, e.g., more than 40% of the area of the seat back is in contact with the occupant; or a part of the area of the seat headrest device is in contact with the occupant, for example, 30% or more of the area is in contact with the occupant; or the seat belt is fastened, etc.

A seat headrest device includes: the first side wing is movably connected with the headrest part, the second side wing is movably connected with the first side wing, and the first loudspeaker module is arranged on the second side wing; the first characteristic position comprises the positions of the head, eyes, ears and the like of the passenger; the first characteristic position may be obtained by a camera in the cabin, for example, an RGB camera or an infrared camera, and the first characteristic position may also be obtained by a detection sensor disposed on the headrest, the cabin side wall, or another position, which is not limited in this application.

Step S2: and controlling the movement of the first side wing and the second side wing according to the first characteristic position so that the first loudspeaker module faces the first characteristic position.

Wherein the first speaker module comprises a plurality of first speakers, and in some embodiments the first speaker module further comprises a slide for sliding the speakers therein. When the first loudspeaker module faces the first characteristic position, the included angle between the sound emitting direction of each loudspeaker of the first loudspeaker module and a connecting line between the loudspeaker and the first characteristic position is smaller than a first angle.

In some embodiments, the movement control of the first and second side wings may be further implemented in response to a user operation, for example, by the user pressing a control key provided on the seat or by the user pressing a control key provided at another location on the vehicle, so that the first speaker module faces the first characteristic position. Or, the user rotates a rotating button arranged on the seat, and the rotating button is rotated to adjust the moving degree of the first side wing and the second side wing, so that the first loudspeaker module faces to the first characteristic position.

In some embodiments, it may also be in response to a user's voice instruction, such as: the user sends a voice command of 'please unfold the side wings of the headrest device' to realize the movement control of the first side wings and the second side wings, so that the first loudspeaker module faces to the first characteristic position. The voice instruction can be acquired through the microphone and recognized through voice recognition and other modes to acquire the intention and the slot position of the user, and then the movement of the first side wing and the second side wing is controlled according to the intention and the slot position of the user.

In some embodiments, the movement control of the first wing and the second wing may be further implemented in response to an operation instruction issued by a user through an operation terminal (e.g., a mobile phone, a smart watch, a smart tablet, a remote controller, etc.), for example, the user inputs an unfolding angle, an unfolding position, or manually controls movement of a simulated headrest wing of a display screen on the display screen of the terminal, so that the first speaker module faces the first feature position.

In some embodiments, the first speaker module may be further oriented toward the first characteristic position in response to a physical manipulation by a user, for example, the user manually moves the first wing and the second wing to their desired positions or the first characteristic position, thereby implementing a movement control of the first wing and the second wing.

In some embodiments, the first speaker module is located in a plane, the first speaker module is disposed in an axisymmetric or centrosymmetric manner, and when an included angle between a line connecting the center of the first speaker module and the first feature position and a normal line of the plane passing through the center of the speaker module is smaller than a first angle, the first speaker module faces the first feature position.

In some embodiments, the movement of the first wing may be driven by a first drive mechanism; the movement of the second wing is driven by a second drive mechanism. For a detailed description of the first driving mechanism and the second driving mechanism, reference may be made to the description of the wing driving mechanism for driving the first wing and/or the second wing in the first embodiment and the second embodiment of the present application, and for brevity, no further description is provided here.

In some embodiments, when the first speaker module group faces the first characteristic position, the facing direction refers to that a point of the first characteristic position orthographically projected on a plane where the first speaker module group is located is in a region of the first speaker module group.

In some embodiments, when an included angle between a connecting line between the first speaker module and the ear of the passenger and a connecting line between two ears of the passenger is smaller than a preset angle, the sound emitting direction of the first speaker module can be over against the listening position of the user, so that the sound leakage is greatly reduced, and the exclusive requirement of the user on the audio is met.

In some embodiments, the first wing and the second wing may also be controlled to move according to a second wing position set by a user, so that the second wing moves to the second wing position.

When the first characteristic position of the passenger cannot be obtained, or the user wants to adjust the position of the second side wing according to the preference of the user, the position of the second side wing may be set according to the requirement of the passenger, for example, the position of the second side wing may be displayed on a vehicle-mounted central control screen, and the position of the second side wing relative to the passenger is controlled by operating the central control screen, which is not limited in the present application.

In some embodiments, when the first characteristic position of the occupant is not available, or the user wishes to adjust the position of the second side wing according to his preference, the movement of the first side wing, the second side wing, and the speaker module may be achieved by a physical button or a physical rotation button provided on the seat, the car machine, or the headrest of the seat, etc.

In particular, when a user presses a physical key, the first wing and/or the second wing may move to a particular position. Alternatively, the moving position of the first wing and/or the second wing may be controlled by controlling the time of pressing the physical key, for example, the first wing and/or the second wing may be moved back and forth within a preset range when the user presses the physical key, and the physical key may be released when the first wing and/or the second wing is moved to the user's desired position.

Specifically, when the user presses the physical key, the speaker of the speaker module may move to another specific position. Alternatively, the degree of movement of the speaker module may be controlled by controlling the time when the physical key is pressed, for example, when the physical key is pressed, the speaker in the speaker module may move back and forth within a preset range, and when the speaker moves to a desired position of a user, the key may be released.

Specifically, the user may also control the degree of movement (the deployment angle) of the first wing and/or the second wing by rotating the rotation button, or control the position of the speaker module by rotating the rotation button.

In some embodiments, the control method further comprises: controlling the movement of the loudspeaker according to a listening pattern comprising: a surround mode, an exclusive mode, or a personalized mode, in the exclusive mode, the first speaker is located at a center of the second wing. In some embodiments, when the first speaker modules are 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, and the larger the directivity, the less the sound leakage, and the stronger the exclusivity:

the theta is an included angle between a connecting line of an intersection point of a normal line of a plane where the first loudspeaker module is located on the plane and the first characteristic position and the normal line; k is the wave number of the first speaker, which increases with the increase of the frequency of the first speaker, N is the number of the first speakers, and d is the distance between two adjacent first speakers. Thus, the less sound leakage the first speaker is located in the center of the first wing or the second wing.

In some embodiments, the speaker may be located at an edge of the second wing in the surround mode. When the user does not need to solely share audio, the speaker may be controlled to be located at an edge position of the second wing.

In some embodiments, in the personalized mode, the user may set the position of the speaker according to his or her own needs, and the set speaker position may be stored in the memory, and when the system recognizes the user, the speaker is controlled to move to the position set by the user.

In some embodiments, the movement of the plurality of speakers may be driven by a third drive mechanism. For a detailed description of the third driving mechanism, reference may be made to the description of the driving mechanism for the speaker in the first and second embodiments of the present application, and for the sake of brevity, the detailed description is omitted here.

In some embodiments, the second speaker module is mounted on the first side wing, and when the listening mode is the exclusive mode, the second speaker module mutes and the first speaker module sounds. When the passenger selects the exclusive mode, the second speaker module can be muted, for example, the second speaker module is powered off; when the passenger selects the surround mode, the first loudspeaker module and the second loudspeaker module can both produce sound, and therefore the multi-channel surround sound effect is achieved.
