Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application. The reference numbers in the present application are only used for distinguishing the steps in the scheme and are not used for limiting the execution sequence of the steps, and the specific execution sequence is described in the specification.

In order to solve the problems in the prior art, embodiments of the present application provide a vehicle headrest sound control method, where a vehicle headrest sound to which the method is applied is provided in a seat headrest of a vehicle, and includes a left speaker and a right speaker that are telescopically movable. That is, the vehicle headrest sound system according to the embodiment of the present application is a headrest sound system having a telescopic adjustment function.

Fig. 1 is a schematic view of a robot arm mechanism of a headrest sound system for vehicles according to an embodiment of the present invention, and as shown in fig. 1, the robot arm of the headrest sound system includes a headrest connection part 10 and a speaker connection part 20, which may be connected to each other by a spring connection part 30. The headrest connection member 10 is connected to a functional accessory of the vehicle headrest audio provided in the seat headrest, and the speaker connection member 20 is connected to a speaker of the vehicle headrest audio.

The spring connecting part 30 is a part having an elastic function, such as a spring, and can play a role of force buffering when the mechanical arm drives the speaker to move telescopically and adjust through the connecting function of the spring connecting part 30.

Left and right speakers of the in-vehicle headrest audio may be provided on left and right sides of the seat headrest or on the front side of the headrest, respectively, and each speaker is connected to the speaker connecting part 20 on the corresponding side. Fig. 1 shows only the arms of the headrest sound corresponding to one speaker, and the headrest sound may be configured with two arms. One speaker can be connected to the headrest sound by the mechanical arm corresponding to the headrest connection member 10, the speaker connection member 20, and the spring connection member 30.

The speaker and the arm of headrest stereo set can be at ordinary times the inside of inline seat headrest to accessible mechanical force control arm and the speaker that corresponds stretch out in going out the headrest, and flexible the removal realizes that height, the direction of speaker are adjusted. The user's that speaker and seat headrest correspond ear laminating, the speaker can be for example the form of ear muff, and the outside cladding of ear muff has soft material, can avoid the uncomfortable sense of causing of ear when metal speaker is direct and user's ear contact.

Next, a vehicle headrest sound control method according to an embodiment of the present application will be described with reference to fig. 2, and fig. 2 is a flowchart illustrating the vehicle headrest sound control method according to the embodiment of the present application.

As shown in fig. 2, the method comprises the following steps:

step 102, when an instruction for starting the target headrest sound is received, acquiring the ear position of a user corresponding to the target headrest sound;

104, controlling the loudspeaker of the target headrest sound to move to contact the ear of the user according to the ear position of the user;

step 106, monitoring the pressure generated by the loudspeaker on the ear of the user in the process of contacting the loudspeaker with the ear of the user;

and step 108, controlling the loudspeaker to move to fit the ear of the user according to the pressure.

In step 102, the instruction for enabling the target headrest audio may be an instruction for enabling the headrest audio function through in-vehicle voice, key press, gesture, and the like, and the triggering of the instruction may be automatically started by the vehicle control system in a specific scene, for example, when it is monitored that a driver is making a call, an in-vehicle driver and an in-vehicle passenger are on-line meeting through a car machine, or the in-vehicle driver and the in-vehicle passenger are in-vehicle games, karaoke, live broadcast, and the like, the vehicle control system actively prompts the user whether to start; or it may be actively turned on by the user.

The enabled target headrest sounds include selectable independently enabled position-designated headrest sounds, such as selectable enabling of a primary driver seat headrest sound, a co-driver seat headrest sound, a second row of left headrest sounds, a second row of right headrest sounds, a third row of headrest sounds, and the like, or selectable enabling of all seat headrest sounds in the vehicle.

Based on the solution provided by the foregoing embodiment, optionally, in step 102, acquiring the ear position of the user corresponding to the target headrest sound device includes: respectively acquiring the height of the ear of a user, the distance between the ear of the user and the left side and the right side of a headrest of a seat corresponding to the target headrest sound, and the distance between the ear of the user and the front side of the headrest of the seat; and determining the three-dimensional coordinate position of the ear of the user relative to the headrest of the seat according to the height and the distance of the ear of the user.

Specifically, the image of the head of the user and the image of the corresponding seat headrest together can be acquired through the in-vehicle camera, and the size of the seat headrest is used as a reference object, so that the size of the head of the user is determined. After the user's head size is determined, the height of the user's ear, as well as the distance between the user's left ear and the left side of the seat headrest and the distance between the user's right ear and the right side of the seat headrest, may then be determined, thereby determining the two-dimensional coordinate position of the user relative to the seat headrest. Further, the degree of distance of the user's ear from the headrest in the front-rear direction can be determined according to the distance between the user's ear and the front side of the headrest of the seat. Thus, the three-dimensional coordinate position of the ear of the user relative to the headrest of the seat can be determined in conclusion.

In the embodiment of the present application, optionally, after receiving the instruction to enable the target headrest sound system in step 102, it may also be detected whether the target user is present in the seat corresponding to the target headrest sound system through an in-vehicle camera or a seat pressure sensor of the vehicle. If the target user does not exist, the target headrest sound does not respond to the instruction; and if the target user exists, the target headrest sound receives the instruction and responds to the instruction so as to trigger the step 102 of acquiring the ear position of the user corresponding to the target headrest sound.

That is, after receiving the function of opening the headrest audio, the user can detect whether the seat position corresponding to the headrest is occupied or not through the image shot by the camera in the vehicle or the seat pressure detected by the pressure sensor. When no person is detected in the corresponding seat, the headrest sound does not respond to the instruction; when the corresponding seat is detected to be a person, the headrest stereo receives the instruction and responds.

Based on the solution provided by the foregoing embodiment, optionally, in step 104, controlling the speaker of the target headrest sound to move to contact with the ear of the user according to the ear position of the user, includes: controlling a left loudspeaker of the target headrest sound to move to the left ear position of the user in a stretching mode according to the ear position of the user; and controlling the right loudspeaker of the target headrest sound to move to the right ear position of the user in a stretching mode.

After the position of the ear of the user is determined, the loudspeaker of the corresponding seat headrest sound slowly extends out of the seat headrest according to the position of the ear of the user and moves to a position close to the ear of the user. The speakers of different sides move telescopically towards the user's ears of the corresponding sides to make precise contact with the corresponding user's ears.

In step 106, pressure detection may be performed on the contacted user's ear by a pressure sensor built into the speaker. When the speaker of the seat headrest audio does not contact the ear of the corresponding user, the pressure is 0. When the pressure is higher than 0 just after the ear of the corresponding user is contacted, the pressure sensor can be activated to work. Thus, as the speaker is brought closer to the user's ear, the corresponding pressure is greater, and conversely, smaller.

Based on the solution provided by the foregoing embodiment, optionally, in step 108, controlling the speaker to move to fit the ear of the user according to the pressure includes: detecting whether the pressure meets a set threshold value; when the pressure is lower than a set threshold value, controlling the left loudspeaker and the right loudspeaker to correspondingly move towards the directions close to the left ear and the right ear of the user; when the pressure is higher than the set threshold value, controlling the left loudspeaker and the right loudspeaker to correspondingly move towards the directions far away from the left ear and the right ear of the user; and when the pressure is equal to the set threshold value, controlling the left loudspeaker and the right loudspeaker to stop moving.

The set threshold value represents the degree of tightness of the corresponding loudspeaker and the ear of the user, and the larger the set threshold value is, the tighter the loudspeaker is correspondingly attached to the ear of the user, and the larger the pressure correspondingly generated is; the smaller the threshold value is set, the looser the loudspeaker is correspondingly attached to the ear of the user, and the smaller the pressure generated correspondingly.

Therefore, when the detected pressure is lower than the set threshold value, the corresponding loudspeaker is controlled to move forwards in a direction close to the ear of the corresponding user; when the detected pressure is higher than the set threshold value, controlling the corresponding loudspeaker to retract and move towards the direction far away from the ear of the corresponding user; and when the detected pressure is equal to the set threshold value, controlling the corresponding loudspeaker to stop moving towards the direction of the ear of the corresponding user and keeping the current position.

Optionally, before detecting whether the pressure meets the set threshold, the method may further include: acquiring at least one of the fitting degree and the noise reduction degree of a loudspeaker set by a user; and determining a set threshold according to at least one of the fitting degree and the noise reduction degree.

The fitting degree is related to the fitting tightness degree of the loudspeaker corresponding to the pressure, and the loudspeaker can be customized by a user and can also be selected by the user through factory setting of a plurality of threshold values. And selecting the corresponding fitting degree in advance according to the tightness preference of the user when wearing the loudspeaker earphone. The higher the fit, the tighter the speaker fits to the user's ear, and vice versa.

The noise reduction is realized by blocking external noise to enter after the loudspeaker is attached to the ear part. The fitting degree is also related to the fitting tightness degree of the loudspeaker corresponding to the pressure, and the fitting degree can be customized by a user or can be selected by the user through factory setting of a plurality of threshold values. The higher the noise reduction, the tighter the speaker fits to the user's ear, and vice versa.

For example, the noise reduction is achieved when the speaker just touches and covers the ear of the user, but the fitting degree does not reach the set value at the moment, and the speaker can be controlled to continue to be pressed towards the ear of the user.

Select the speaker laminating degree of headrest stereo set and fall the degree of making an uproar, through the laminating degree with fall the selection of the degree of making an uproar, decide the built-in pressure sensor's of headrest stereo set reference threshold value to the elasticity degree of deciding headrest stereo set speaker laminating user ear.

Through speaker laminating user ear, can reduce headrest stereo set speaker's hourglass sound by a wide margin, can promote headrest stereo set speaker's sound privacy, can promote by a wide margin and make a call, the use under the scene such as online meeting experiences on the car. Through speaker laminating user's ear, can reach the effect of making an uproar of falling voluntarily, reduce the inside and outside noise of vehicle. In addition, the loudspeaker is close to the ear, so that better music experience can be brought, and the use experience under the scenes of in-car games, in-car karaoke, in-car live broadcast, in-car games and the like can be greatly improved.

Therefore, the requirements of the user on comfort, noise reduction effect and privacy effect can be guaranteed.

Optionally, the vehicle headrest sound control method according to the embodiment of the present application further includes: continuously monitoring the ear position of a user and the pressure of the loudspeaker on the ear of the user in the process that the loudspeaker of the target headrest sound is attached to the ear of the user; when user's ear position and pressure change, according to user's current ear position and current pressure, control speaker corresponds flexible removal in order to laminate user's ear.

When a user wears the loudspeaker, if the user swings or turns the head, the pressure generated between the loudspeaker and the ear changes, and the corresponding loudspeaker can be adjusted in a telescopic mode according to the relative direction of the movement of the ear at the moment for keeping the wearing comfort of the user. Specifically, the ear position of the user and the corresponding generated pressure may be obtained according to the above steps 102 to 108, the speaker is controlled to move to the corresponding ear position to precisely fit the ear, and the position is maintained when the pressure reaches the set threshold.

The built-in pressure sensor that the accessible corresponds the speaker lasts monitoring pressure, ensures that the pressure that pressure sensor monitored keeps unanimous with the threshold value of setting for to this constantly carries out the flexible regulation of small-amplitude to the speaker of headrest stereo set, ensures that the speaker is in the state of laminating user's ear, and the monitoring and the intelligent flexible regulation through the built-in pressure sensor of speaker can let the user keep comfortable always.

This application embodiment finds user's ear position through fixing a position earlier, again according to the speaker contact that ear position control corresponds and laminating ear. In the fitting process, the position change of the ear of the user and the pressure generated by the ear are continuously monitored, and therefore the loudspeaker is controlled to adjust and move in real time to keep a state of being fitted with the ear.

When the user is detected to leave the seat, the extended headrest sound is automatically retracted into the headrest of the seat, and the headrest sound system is prevented from being damaged by other behaviors. Whether the user leaves after finishing using is intelligently monitored, the extended loudspeaker is timely withdrawn, and the loudspeaker can be protected from being damaged.

Under the incomplete automatic driving condition, whether the driving needs are the main driving needs or not is intelligently identified, if the driving needs are the main driving needs, only the single-side headrest loudspeaker responds to the function, and the driving safety is guaranteed.

As described above, the movement of the speaker can be performed by controlling the robot arm including the headrest coupling part 10, the speaker coupling part 20, and the spring coupling part 30 can play a role of force relief in adjusting the fitting of the speaker to the ear of the user, thereby preventing the head or face of the user from being injured by the hard object of the robot arm.

In one embodiment, when the target headrest sound comprises a primary driving headrest sound of the vehicle, before acquiring the ear position of the target headrest sound corresponding to the user, the method further comprises: judging whether the vehicle is in full automatic driving; and when the vehicle is in full automatic driving, acquiring the left and right ear positions of the main driving headrest sound corresponding to the user.

Judging whether the vehicle is in a running state or not under the condition that the vehicle is not driven completely automatically; under the condition that the vehicle is in the driving state, the position of one-side ear corresponding to the user is obtained according to the position of the main driving seat, so that the loudspeaker corresponding to the position of the one-side ear in the main driving headrest sound box is controlled to move to fit the one-side ear of the user.

For driving safety, a driver controls to wear only one-side speaker earphones or not to wear the earphones in order to prevent the condition that the driver cannot hear the outside during driving. Therefore, in response to the non-fully automatic driving, it is necessary to control the speaker of the headrest sound in the main driving seat position during the driving of the driver, for example, the main driving seat is located on the left side, and the speaker is worn on the right ear of the driver in response to the sound of the outside vehicle heard by the left ear. For full automatic driving, driving is independent of the driver, so that the positions of both ears of the user on the main driving seat can be acquired, thereby controlling the user on the main driving seat to wear the speakers of both ears simultaneously.

When the vehicle does not reach the full automatic driving level, whether the current vehicle is in the process of traveling is detected, when the vehicle is in the process of traveling, if the main driving seat is located on the left side, the headrest sound box only extends out of a loudspeaker on the right side of a driver, in order to prevent noise reduction and avoid tight fitting, the threshold value of a pressure sensor arranged in the loudspeaker on the right side can be set to be the lowest, the headrest loudspeaker is kept in light contact with the ear of the user, and therefore driving safety is guaranteed.

Referring now to fig. 3, fig. 3 is an exemplary flowchart of an in-vehicle headrest sound control method according to an embodiment of the present application. As shown in fig. 3, the method comprises the following steps:
