[0037] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings.

[0038] Figure 1 are diagrams for explaining the configuration of a vehicle according to some forms of the present disclosure.

[0039] For ease of description, the following Figure 1 As shown, the direction in which the vehicle 1 moves forward is generally referred to as the front, and the left direction and the right direction are distinguished based on the front. In addition, the direction relative to the floor of the vehicle 1 is referred to as the vertical direction, and the direction parallel to the ground is defined as the horizontal direction.

[0040] Reference Figure 1 , an instrument panel 5 may be provided in front of a driver's seat and a passenger seat of the vehicle 1. Various electronic devices such as a cluster, an AVN device, and a storage box may be provided on the instrument panel 5.

[0041] For example, a center speaker 10 for outputting various sounds may be provided at the center of an upper portion of the instrument panel 5 .

[0042] A bracket 20 on which the user terminal device 200 can be placed may be provided near the center speaker 10 on the instrument panel 5 .

[0043] The bracket 20 may be provided on the dashboard 5 within a preset distance from the center speaker 10 , and, for example, may be provided on top of the center speaker 10 .

[0044] In addition, the vehicle 1 may be provided with cameras 30 for capturing images of passengers. These cameras 30 may be located in front of the driver's seat and the front passenger seat so as to capture images of passengers such as the driver sitting in the driver's seat of the vehicle 1, a fellow passenger sitting in the front passenger seat of the vehicle 1, and a fellow passenger sitting in the rear seat of the vehicle 1.

[0045] For example, the camera 30 may be disposed on the top in front of the driver's seat, but if the camera 30 is located at a position where it can photograph passengers, it may be disposed without limitation.

[0046] Figure 2 is an enlarged view of an interior area of ​​a vehicle of some forms of the present disclosure.

[0047] Reference Figure 2 , the bracket 20 may be disposed within a preset distance from the center speaker 10 , and the user terminal device 200 fixed to the bracket 20 may reflect the sound output from the center speaker 10 .

[0048] The bracket 20 may be configured to tilt or swivel. Therefore, the user terminal device 200 fixed to the bracket 20 may also be tilted or swivel.

[0049] The tilting of the bracket 20 may refer to the vertical rotation of the bracket 20. The rotation of the bracket 20 may refer to the horizontal rotation of the bracket 20.

[0050] To this end, the bracket 20 may include a bracket unit 21 configured to tilt and rotate.

[0051] The user terminal device 200 may include a user's smartphone, laptop computer, smart watch, etc., but any terminal device that can perform wireless communication and / or wired communication with the vehicle 1 may be used without limitation.

[0052] In this case, the user terminal device 200 may include a flexible device. A flexible device is a device made of a bendable material such as a plastic substrate. A flexible device is a device that is lighter than other devices and has a flexible material without breaking, thereby enabling folding, rolling, or bending.

[0053] When a portion where the flexible device is folded is defined as a folding line, the flexible device may be divided into two regions (hereinafter referred to as a “first region and a second region”) based on the folding line.

[0054] A user may fold or unfold the flexible device by applying an external force to the first and second regions of the flexible device.

[0055] Hereinafter, the angle formed by the first area and the second area of ​​the flexible device is defined as a folding angle of the flexible device.

[0056] The bracket 20 may include an angle adjustment device 22 for adjusting the folding angle of the flexible device.

[0057] The angle adjustment device 22 may include a first fixing portion for fixing a first area of ​​the flexible device and a second fixing portion for fixing a second area of ​​the flexible device.

[0058] The first fixing portion and the second fixing portion included in the angle adjustment device 22 are respectively configured to rotate independently, so that the folding angle of the flexible device can be adjusted.

[0059] For example, when the second fixing portion for fixing the right area of ​​the flexible device is rotated toward the center speaker 10 while the first fixing portion for fixing the left area of ​​the flexible device is not moved, the folding angle of the flexible device can be reduced.

[0060] The user terminal device 200 according to one embodiment may include at least one microphone 210. The microphone 210 of the user terminal device 200 may receive a sound signal output from the center speaker 10 to perform processing such as amplification and noise removal.

[0061] For example, the microphone 210 may detect the sound pressure of the sound output from the center speaker 10 .

[0062] A portion of the sound signal output from the center speaker 10 may be reflected by the user terminal device 200 , and the other portion of the sound signal may be diffracted and propagate toward the rear surface of the user terminal device 200 (ie, the windshield of the vehicle 1 ).

[0063] The microphone 210 of the user terminal device 200 may preferably be located at a position away from the center speaker 10 in order to detect the sound pressure of the diffracted sound from the sound output from the center speaker 10 .

[0064] In addition, the user terminal device 200 may include a plurality of microphones, and when the first microphone 210 is disposed in the first area, a second microphone (not shown) may be disposed in the second area.

[0065] Figure 3 is a control block diagram of a vehicle of some forms of the present disclosure.

[0066] Reference Figure 3 According to one embodiment, a vehicle 1 may include a central speaker 10 provided on a dashboard 5, a bracket 20 provided near the central speaker 10 to fix a user terminal device 200, a camera 30 for acquiring an image of a passenger, a transceiver 40 capable of performing wired / wireless communication with the user terminal device 200 fixed to the bracket 20, and a controller 50 for controlling various configurations of the vehicle 1.

[0067] The center speaker 10 may output sound under the control of the controller 50 .

[0068] The center speaker 10 may include an amplifier (not shown) that supplies current for generating sound, and the center speaker 10 may generate sound based on the current supplied from the amplifier.

[0069] For example, when the magnitude of the current supplied from the amplifier is larger, the sound pressure of the sound that the center speaker 10 can generate is larger, and when the magnitude of the current supplied from the amplifier is smaller, the sound pressure of the sound that the center speaker 10 can generate is smaller.

[0070] The bracket unit 21 of the bracket 20 may be tilted and / or rotated under the control of the controller 50 , and the angle adjustment device 22 of the bracket 20 may adjust the folding angle of the flexible device.

[0071] To this end, the bracket 20 may include a driving unit (not shown).

[0072] The driving unit may tilt or rotate the bracket unit 21 or rotate the angle adjustment device 22 based on a control signal of the controller 50 .

[0073] Specifically, the driving unit may include a driving motor that generates driving force to tilt and rotate the bracket unit 21 or rotate the angle adjustment device 22 , and a driving circuit that supplies driving power to the driving motor according to a control signal of the controller 50 .

[0074] The driving motor may receive driving power from the driving circuit and convert the received driving power into a rotational force. In addition, the bracket unit 21 may be tilted or rotated by the converted rotational force, and the angle adjustment device 22 may be rotated by the converted rotational force.

[0075] For example, the rotational force generated by the drive motor may be transmitted to the bracket 20 through gears, etc. In other words, the drive motor may tilt or rotate the bracket 20 or rotate the angle adjustment device 22 through gears, etc.

[0076] As another example, the rotational force generated by the driving motor may be transmitted to the bracket 20 through a fluid and a piston, etc.

[0077] Such a drive circuit may include a switching element such as a relay for supplying drive power to the drive motor or for blocking the drive power.

[0078] In addition, the stand 20 may include a wireless power transmitter (not shown) for transmitting wireless power to the fixed user terminal device 200 , and a short-range communication module for communicating with the user terminal device 200 .

[0079] The camera 30 may acquire an image of a passenger, process the acquired image of the passenger, and transmit it to the controller 50 .

[0080] The camera 30 may be any device capable of capturing images of passengers. For example, the camera 30 may be a CMOS (Complementary Metal Oxide Semiconductor) image sensor or a CCD (Charge Coupled Device) image sensor.

[0081] The transceiver 40 may communicate with the user terminal device 200 to transmit various data and / or information and / or commands to the user terminal device 200 , and may receive various data and / or information and / or commands from the user terminal device 200 .

[0082] To this end, the transceiver 40 can be implemented using a communication chip, an antenna, and related components to access a wireless communication network. That is, the transceiver 40 can be implemented as various types of communication modules capable of short-range or long-range communication with the user terminal device 200.

[0083] For example, the transceiver 40 may include a Bluetooth module capable of performing Bluetooth communication with the user terminal device 200 .

[0084] In addition, the transceiver 40 may communicate with the bracket 20 in a wired manner to transmit various data and / or information and / or commands to the bracket 20 , and may receive various data and / or information and / or commands from the bracket 20 .

[0085] At this time, the bracket 20 can transmit various data and / or information and / or commands received from the transceiver 40 to the user terminal device 200 fixed to the bracket 20, and can transmit various data and / or information and / or commands received from the user terminal device 200 to the transceiver 40.

[0086] That is, the transceiver 40 may communicate with the user terminal device 200 in a wireless or wired manner.

[0087] To this end, the controller 50 may include: at least one memory storing a program for performing the above-mentioned operations and the operations described below; and at least one processor for executing the stored program. When the controller 50 includes multiple memories and multiple processors, the multiple memories and multiple processors may be integrated into a single chip or may be physically separated.

[0088] For example, the controller 50 may control the bracket 20 based on an image received from the camera 30 , and control the center speaker 10 based on data received from the transceiver 40 .

[0089] Hereinabove, the arrangement, structure, and functions of the various components of the vehicle 1 have been described.

[0090] In the following, reference will be made to Figure 4 and Figure 5 Control methods of the vehicle 1 using various configurations of the vehicle 1 are described.

[0091] Figure 4 is a flow chart of a method of controlling a vehicle of some forms of the present disclosure. Figure 5 is a flow chart of a method of controlling a vehicle of some forms of the present disclosure.

[0092] Reference Figure 4 , the camera 30 can obtain the image of the passenger and transmit it to the controller 50 (1000).

[0093] The controller 50 can determine the position of the passenger's ears based on the image of the passenger, and determine the tilt angle of the bracket 20 (hereinafter referred to as the "first angle") and / or the rotation angle of the bracket 20 (hereinafter referred to as the "second angle") and / or the folding angle of the flexible device (hereinafter referred to as the "third angle") based on the position of the passenger's ears (1100).

[0094] Specifically, the controller 50 may determine the coordinates of the passenger's ear based on the center point of the center speaker 10 , and may determine the first angle, the second angle, and the third angle based on the coordinates of the passenger's ear.

[0095] For ease of explanation, it is assumed that the passenger is the driver, the x-axis is the rear, the y-axis is the left direction, and the z-axis is the vertical direction.

[0096] The controller 50 may form a coordinate system using the center of the center speaker 10 as an origin and calculate the X-coordinate, the Y-coordinate, and the Z-coordinate of the driver's ear.

[0097] The controller 50 may determine a first angle, a second angle, and a third angle at which the sound signal output from the center speaker 10 is reflected by the user terminal device 200 to reach the coordinates of the driver's ear.

[0098] For example, the controller 50 can calculate the incident angle of the sound signal output from the central speaker 10 to the user terminal device 200 and the reflection angle of the sound signal reflected from the user terminal device 200 based on the x, y and z coordinates of the driver's ear and the x, y and z coordinates of the user terminal device 200 assumed to be fixed to the bracket 20.

[0099] Thereafter, the controller 50 may determine the first angle, the second angle, and the third angle based on the calculated incident angle and reflection angle.

[0100] The controller 50 may control the bracket 20 to tilt at a first angle and rotate at a second angle (1200). Specifically, the controller 50 may control a driving unit included in the bracket 20 so that the bracket 20 tilts at a first angle and rotates at a second angle.

[0101] When the user terminal device 200 is a flexible device, the controller 50 may control the angle adjustment device 22 to fold the flexible device to a third angle. Specifically, the controller 50 may control the driving unit included in the bracket 20 to fold the flexible device to a third angle.

[0102] According to the disclosed embodiment, the sound output from the center speaker 10 can be effectively delivered to the user by adjusting the tilt angle, rotation angle of the bracket 20 and the folding angle of the flexible device placed on the bracket 20 according to the position of the passenger's ears.

[0103] Reference Figure 5 , the transceiver 40 may receive sound pressure information from the user terminal device 200 and transmit the received sound pressure information to the controller 50 ( 2000 ).

[0104] In this case, the sound pressure information transmitted by the user terminal device 200 refers to sound pressure information received from the microphone 210 provided in the user terminal device 200 .

[0105] As described above, the microphone 210 provided in the user terminal device 200 may be located away from the center speaker 10 , and thus the sound pressure information received by the microphone 210 may refer to the sound pressure information of the sound that is diffracted but not reflected by the user terminal device 200 .

[0106] The controller 50 may calculate loss sound pressure based on sound pressure information received from the microphone 210 of the user terminal device 200 through the transceiver 40 ( 2100 ).

[0107] For example, the controller 50 may calculate the loss sound pressure in proportion to the sound pressure magnitude included in the sound pressure information received from the microphone 210 of the user terminal device 200 .

[0108] When the user terminal device 200 includes a plurality of microphones, the controller 50 may calculate the loss sound pressure more accurately based on the sound pressure information received from the plurality of microphones of the user terminal device 200 .

[0109] For example, the controller 50 may calculate an average value of the sound pressure magnitude included in the sound pressure information received from each of the plurality of microphones, and may calculate the loss sound pressure in proportion to the average sound pressure magnitude.

[0110] The controller 50 may compensate for the output of the center speaker 10 based on the calculated loss sound pressure ( 2200 ).

[0111] For example, when the calculated loss sound pressure increases, the controller 50 may increase the output of the center speaker 10 .

[0112] That is, the controller 50 may adjust the sound pressure of the sound output from the center speaker 10 based on the sound pressure information received from the microphone 210 of the user terminal device 200 through the transceiver 40. For example, the controller 50 may adjust the sound pressure of the sound output by the center speaker 10 in proportion to the sound pressure magnitude included in the sound pressure information received from the microphone 210 of the user terminal device 200.

[0113] In addition, when the user terminal device 200 includes multiple microphones, the controller 50 can calculate the average value of the sound pressure information received from the multiple microphones of the user terminal device 200, and can proportionally adjust the sound pressure of the sound output from the center speaker 10 according to the calculated average sound pressure.

[0114] Specifically, the controller 50 may control the amplifier included in the center speaker 10 to adjust the sound pressure of the sound output from the center speaker 10 .

[0115] According to the disclosed embodiment, by compensating for the sound pressure lost by the user terminal device 200 , it is possible to prevent the sound pressure of the sound heard by the passenger from being deteriorated.

[0116] Although not shown in the drawings, the transceiver 40 can receive information from the bracket 20 that the user terminal device 200 has been placed, and when the user terminal device 200 is fixed to the bracket 20, the controller 50 can control the transceiver 40 to transmit a signal for changing the user terminal device 200 to a silent mode.

[0117] The silent mode may refer to a mode without sound output and vibration.

[0118] Therefore, it is possible to solve the problem that the sound output from the center speaker 10 is deteriorated due to the sound or vibration output from the user terminal device 200 .

[0119] According to the disclosed embodiments, passenger satisfaction may be improved by guiding the sound output from the center speaker 10 to the passengers without changing the structure of the center speaker 10 .

[0120] By adjusting the tilt angle and rotation angle of the bracket according to the position of the passenger's ears, the passenger can hear the sound more effectively.

[0121] In addition, based on compensating the output of the center speaker by calculating the lost sound pressure of the sound output from the center speaker, the passenger can hear the sound more effectively.

[0122] On the other hand, the disclosed exemplary embodiments may be implemented in the form of a recording medium for storing instructions that can be executed by a computer. The instructions may be stored in the form of program code, and when executed by a processor, a program module may be generated to perform the operations of the disclosed exemplary embodiments. The recording medium may be implemented as a computer-readable recording medium.

[0123] Computer-readable recording media include all types of recording media having stored therein instructions that can be decoded by a computer, such as read-only memory (ROM), random access memory (RAM), magnetic tape, magnetic disk, flash memory, optical data storage device, etc.

[0124] As described above, the disclosed exemplary embodiments have been described with reference to the accompanying drawings. Although example embodiments of the present disclosure have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and concepts of the present disclosure, the scope of which is defined in the claims and their equivalents.
