[0002] A speaker is a device that restores an electrical signal into a sound signal, and the restoration authenticity will be an important criterion for evaluating the performance of the speaker. An active speaker is a sound system with a power amplifier (i.e., a power amplifier), which integrates the power amplifier and the speaker sound system, and can be directly paired with a general sound source (such as a walkman, a CD player, a DVD player, a video recorder, etc.) to form a complete audio combination.

[0003] In the related art, vehicle-mounted speakers are generally set to be fixed in the vehicle body and are front speakers located on both sides of the front doors of the vehicle. However, the listening environment in the car is different from that at home. In order to create a surround sound effect in the car, users usually install a center speaker above the vehicle console to change the sound field and frequency of sound playback, so that the sound balance has a more wonderful listening experience. However, the center speaker is usually fixedly embedded in front of the vehicle console, and the sound emitted is upward and cannot be directed towards the listeners, resulting in a poor surround sound playback effect.

[0054] The realization, functional features, and advantages of the object of the present invention will be further described with reference to the embodiments and the accompanying drawings. Detailed implementation manners

[0055] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0056] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0057] At the same time, the meaning of "and / or" or "and / or" appearing throughout the text is to include three scenarios. Taking "A and / or B" as an example, it includes the scenario of A, or the scenario of B, or the scenario where A and B are satisfied simultaneously.

[0058] In addition, the descriptions such as "first", "second", etc. in the present invention are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of technical solutions conflicts with each other or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0059] A speaker is a device that restores an electrical signal into a sound signal, and the restoration authenticity will be an important criterion for evaluating the performance of the speaker. An active speaker is an audio system with a power amplifier (i.e., a power amplifier), integrating the power amplifier and the speaker sound system, and can be directly paired with general sound sources (such as a walkman, CD player, DVD player, video recorder, etc.) to form a complete audio combination.

[0060] In the related art, the in-vehicle system is generally set to be fixed inside the vehicle body and is a front speaker located on both sides of the front door of the car. However, the listening environment in the car is different from that at home. In order to create a surround in-vehicle listening effect, users usually install a center speaker above the in-vehicle center console to change the sound field and frequency of sound playback, so that the sound balance has a more wonderful listening experience. However, the center speaker is usually fixedly embedded in front of the car center console, and the sound it emits is upward and cannot be directed towards the listeners, resulting in a poor sound surround playback effect.

[0061] Based on the above concept and problems, the present invention provides a vehicle-mounted system 100. It can be understood that the vehicle-mounted system 100 is applied to an automobile and used as an audio device of the automobile. In this embodiment, the vehicle-mounted system 100 is installed on the center console or other structures of the automobile, and the installation location is not limited herein.

[0062] Please refer to Figures 1 to 12 As shown in the figure, in the embodiment of the present invention, the vehicle-mounted system 100 includes a mounting base 1, a speaker body 2, a driving mechanism, a position detection device 5, and a controller. Among them, the mounting base 1 is provided with a mounting cavity 11 and a rotation hole 12 communicating with the mounting cavity 11. The speaker body 2 is provided with a receiving cavity 211. On the side of the speaker body 2 facing the mounting base 1, there is an activity hole 212 communicating with the receiving cavity 211. The driving mechanism includes a first driving component 3 and a second driving component 4. The first driving component 3 is disposed in the receiving cavity 211 and connected to the speaker body 2. The second driving component 4 is disposed in the mounting cavity 11. Part of the second driving component 4 sequentially passes through the rotation hole 12 and the activity hole 212 and extends into the receiving cavity 211, and is connected to the first driving component 3. The position detection device 5 is disposed on the mounting base 1 and / or the speaker body 2. The controller is electrically connected to the position detection device 5, the first driving component 3, and the second driving component 4.

[0063] In this embodiment, the mounting base 1 is used to install, fix, and protect structures such as the speaker body 2, the driving mechanism, the position detection device 5, and the controller. That is, the mounting base 1 provides an installation basis for structures such as the speaker body 2, the driving mechanism, the position detection device 5, and the controller. It can be understood that the mounting base 1 can be the housing structure of the vehicle-mounted system 100, and the vehicle-mounted system 100 is installed on the vehicle body through the mounting base 1.

[0064] Of course, the mounting base 1 can also be a part of the vehicle body. For example, the mounting base 1 is a structure such as the center console, seat, or ceiling of the vehicle body. At this time, the mounting base 1 and the structures such as the center console, seat, or ceiling of the vehicle body are integrally formed structures, and the installation method is not limited herein.

[0065] It can be understood that a cavity structure is formed inside the mounting base 1, that is, the mounting cavity 11 is provided inside the mounting base 1. In order to facilitate the speaker body 2 and other structures to be located outside the mounting cavity 11 of the mounting base 1, the mounting base 1 is further provided with a rotation hole 12 communicating with the mounting cavity 11. Optionally, the outer contour of the rotation hole 12 can be a circular, elliptical, square, triangular, polygonal, or irregular shape, etc., and the shape is not limited herein.

[0066] Optionally, the speaker body 2 can be a speaker or a speaker structure or a horn structure, etc., which is not limited herein. In this embodiment, the speaker body 2 is provided with a cavity 211. In order to facilitate the speaker body 2 to rotate in different directions through the second driving component 4 of the driving mechanism, an activity hole 212 communicating with the cavity 211 is further provided on the side of the speaker body 2 facing the mounting base 1. It can be understood that the activity hole 212 provides an avoidance space for the second driving component 4.

[0067] In order to enable the speaker body 2 to swing or move in other directions different from the rotation direction, so as to achieve a surround sound effect, thereby realizing an active form of sound perception optimization and effectively improving the user experience. In this embodiment, the first driving component 3 of the driving mechanism is arranged in the cavity 211 and is connected to the speaker body 2. The second driving component 4 of the driving mechanism is arranged in the mounting cavity 11. Part of the second driving component 4 sequentially passes through the rotation hole 12 and the activity hole 212 and extends into the cavity 211, and is connected to the first driving component 3.

[0068] It can be understood that by setting the position detection device 5 and the controller, the controller is electrically connected to the position detection device 5, the first driving component 3 and the second driving component 4. Thus, the position detection device 5 is used to detect the position of the user and feedback the detection signal to the controller. Then, after receiving the control signal, the controller controls the second driving component 4 to drive the first driving component 3 to drive the speaker body 2 to rotate, and the first driving component 3 to drive the speaker body 2 to swing, so that the second driving component 4 moves relative to the activity hole 212 along the extension direction of the activity hole 212, and the rotation direction of the second driving component 4 driving the speaker body 2 is different from the swing direction of the first driving component 3 driving the speaker body 2.

[0069] In this embodiment, the second driving component 4 provides a driving force for the rotation of the entire speaker body 2. Optionally, the second driving component 4 can be a structure such as a rotary motor or a rotary cylinder, as long as it is a structure that can drive the speaker body 2 to rotate in a circumferential 360° direction, which is not limited herein. It can be understood that the first driving component 3 provides a driving force for the swing of the speaker body 2. Optionally, the first driving component 3 can be a swing motor or a swing cylinder or a structure that can drive the speaker body 2 to swing, which is not limited herein.

[0070] It can be understood that the activity hole 212 not only provides an avoidance space for the second driving component 4, but also enables the second driving component 4 to move relative to the speaker body 2 in the activity hole 212 when the speaker body 2 swings relative to the second driving component 4. Optionally, the aperture or opening area of the activity hole 212 is much larger than the cross-sectional area of the second driving component 4 passing through the activity hole 212.

[0071] Optionally, the movable hole 212 is in the shape of a strip hole or a kidney-shaped hole. The extending direction of the movable hole 212 is the same as the swinging direction of the speaker body 2, that is, the direction in which the first driving component 3 drives the speaker body 2 to swing.

[0072] In this embodiment, the position detection device 5 can be arranged on the mounting base 1 and / or the speaker body 2 to facilitate detecting the position of the user. It can be understood that the controller can be a control structure arranged in the vehicle-mounted system 100, such as a control circuit, a control panel or other control structures, which are not limited herein. Of course, the controller can also be a control system, a control circuit or a control panel of the vehicle body, etc., which are not limited herein.

[0073] Optionally, the position detection device 5 can be structures such as an infrared sensor, a laser sensor, a displacement sensor, a radar, etc. Of course, the position detection device 5 can also be a communication module such as a Bluetooth detection module or a wifi module arranged in the vehicle-mounted system 100, which are not limited herein.

[0074] In the vehicle-mounted system 100 of the present invention, by arranging the first driving component 3 of the driving mechanism in the cavity 211 of the speaker body 2, the first driving component 3 is connected to the speaker body 2. By arranging the installation cavity 11 in the mounting base 1, the second driving component 4 of the driving mechanism can be installed and fixed by using the installation cavity 11. At the same time, a rotation hole 12 communicating with the installation cavity 11 is arranged on the mounting base 1, and a movable hole 212 communicating with the cavity 211 is arranged on the side of the speaker body 2 facing the mounting base 1. Thus, part of the second driving component 4 can sequentially pass through the rotation hole 12 and the movable hole 212 and extend into the cavity 211, and is connected to the first driving component 3. In this way, the second driving component 4 can be used to drive the first driving component 3 to drive the speaker body 2 to rotate relative to the mounting base 1, and the second driving component 4 is used to support and install the first driving component 3 and the speaker body 2, so that the first driving component 3 and the speaker body 2 swing relative to the mounting base 1 and the second driving component 4, the second driving component 4 moves along the movable hole 212, and the rotation direction of the second driving component 4 driving the speaker body 2 is different from the swinging direction of the first driving component 3 driving the speaker body 2. Therefore, the speaker body 2 realizes three-dimensional rotation through the cooperation of the first driving component 3 and the second driving component 4, so that the vehicle-mounted system 100 realizes a surround sound effect, thereby realizing an active form of sound perception optimization and effectively improving the user experience; further, by arranging the position detection device 5 on the mounting base 1 and / or the speaker body 2, the position detection device 5 is used to scan and locate the position of the user, and the first driving component 3 and the second driving component 4 of the driving mechanism are controlled by the controller to cooperate to drive the speaker body 2 to rotate towards the audition user, realizing a visual experience centered on the user, giving the user an obvious sense of ceremony, and effectively improving the user experience.

[0075] In one embodiment, the position detection device 5 is a radar. The radar is disposed on the mounting base 1. There are multiple radars, and the multiple radars are spaced along the periphery of the mounting base 1.

[0076] In this embodiment, the position detection device 5 can be selected as a radar. As Figures 2 to 4 、 Figures 9 to 12 shown, by disposing the radar on the mounting base 1, the mounting base 1 is used to provide a mounting foundation for the radar, so as to facilitate the radar to scan the user's position.

[0077] Optionally, there are multiple radars, and the multiple radars are spaced along the periphery of the mounting base 1. It can be understood that by setting multiple radars, the position of the user can be located more quickly and accurately. In this embodiment, the mounting base 1 has a mounting surface facing the user direction and a fixing surface for supporting and mounting the speaker body 2. The mounting surface and the fixing surface are arranged at an angle. Optionally, the mounting surface and the fixing surface are perpendicularly arranged.

[0078] In this embodiment, the fixing surface of the mounting base 1 is located on the upper surface of the mounting base 1, and the mounting surface of the mounting base 1 is located on the side surface of the mounting base 1. It can be understood that when the vehicle-mounted system 100 is applied to a vehicle body, the side surface of the mounting base 1 faces the user, and the fixing surface of the mounting base 1 faces the ceiling or roof of the vehicle body.

[0079] In one embodiment, the first driving component 3 includes a first motor 31 and a first rotating shaft 32 connected to the first motor 31. The first motor 31 is disposed in the cavity 211 and is connected to the speaker body 2; the second driving component 4 includes a second motor 41 and a second rotating shaft 42 connected to the output end of the second motor 41. The second motor 41 is disposed in the mounting cavity 11. One end of the second rotating shaft 42 away from the second motor 41 sequentially passes through the rotating hole 12 and the moving hole 212 and extends into the cavity 211, and is connected to the first rotating shaft 32.

[0080] In this embodiment, as Figure 2 、 Figure 6 and Figure 8 shown, by setting the first driving component 3 as the first motor 31 and the first rotating shaft 32, the first motor 31 is connected to the speaker body 2, and the first rotating shaft 32 is connected to the second rotating shaft 42 of the second driving component 4, so that the speaker body 2 is mounted on the second driving component 4 through the first driving component 3.

[0081] It can be understood that in order to enable the first motor 31 to drive the speaker body 2 to swing relative to the mounting base 1 and the second drive assembly 4, the first rotating shaft 32 and the second rotating shaft 42 of the second drive assembly 4 are movably connected, such as a rotational connection in the form of a hole-shaft, or a rotational connection through a hinge or bearing, etc., which is not limited herein. Of course, in order to ensure that the first motor 31 drives the speaker body 2 to swing relative to the mounting base 1 and the second drive assembly 4, the first rotating shaft 32 and the second rotating shaft 42 can also be fixedly connected, and the first motor 31 and the first rotating shaft 32 are rotationally connected, which is not limited herein.

[0082] Optionally, the first motor 31 is a rotary motor, and the first motor 31 drives the speaker body 2 to rotate about the axial direction of the first rotating shaft 32, and the axial direction of the first rotating shaft 32 is perpendicular to the axial direction of the second rotating shaft 42.

[0083] Optionally, the extending direction of the first rotating shaft 32 and the extending direction of the second rotating shaft 42 are arranged at an angle. The axial direction of the first rotating shaft 32 is perpendicular to the extending direction of the movable hole 212. In this embodiment, the axial direction of the second rotating shaft 42, the axial direction of the first rotating shaft 32, and the extending direction of the movable hole 212 are perpendicular to each other. That is, when the axial direction of the second rotating shaft 42 is the Z axis, the axial direction of the first rotating shaft 32 and the extending direction of the movable hole 212 are the X axis and the Y axis directions, respectively.

[0084] In this embodiment, the second motor 41 of the second drive assembly 4 is installed and fixed in the installation cavity 11 of the installation base 1 to provide a rotational driving force for the second rotating shaft 42. One end of the second rotating shaft 42 is connected to the output end of the second motor 41, and the other end of the second rotating shaft 42 sequentially passes through the rotating hole 12 and the movable hole 212 and extends into the accommodating cavity 211, and is connected to the first rotating shaft 32.

[0085] In one embodiment, a connection hole 421 and a fastening hole 422 communicating with the connection hole 421 are provided at one end of the second rotating shaft 42 away from the second motor 41, and the first rotating shaft 32 is inserted into the connection hole 421;

[0086] The second drive assembly 4 includes a fixing member 43, and the fixing member 43 passes through the fastening hole 422 and abuts against and limits the first rotating shaft 32.

[0087] In this embodiment, as Figure 4 , Figure 6 and Figure 8 shown, by using the fixing member 43 to pass through the fastening hole 422 and abut against and limit the first rotating shaft 32, the fixing member 43 is used to realize the fixed connection between the first rotating shaft 32 and the second rotating shaft 42.

[0088] In one embodiment, asFigure 4 , Figure 6 and Figure 8 As shown in Figure 6 and Figure 8 , a protrusion 321 is provided on the outer wall of the first rotating shaft 32, and the protrusion 321 abuts against and limits the outer wall of the second rotating shaft 42. It can be understood that with such a setting, the limiting installation of the first rotating shaft 32 can be realized by using the protrusion 321, so as to prevent the first rotating shaft 32 from detaching from or passing through the connection hole 421 excessively.

[0089] In one embodiment, as shown in Figure 4 a fixing surface 322 is provided on one side of the first rotating shaft 32 facing the fastening hole 422. It can be understood that with such a setting, the contact area between the fixing member 43 and the first rotating shaft 32 can be increased, thereby improving the fixing effect of the fixing member 43.

[0090] In one embodiment, the speaker body 2 includes a front shell 214 and a rear shell 215. The front shell 214 and the rear shell 215 are connected and enclose to form a cavity 211.

[0107] The present invention also provides a control method for the above vehicle-mounted system 100. The specific structure of the vehicle-mounted system 100 refers to the foregoing embodiments. Since the control method of the vehicle-mounted system 100 adopts all the technical solutions of the foregoing embodiments, it at least has all the beneficial effects brought by the technical solutions of the foregoing embodiments, which will not be elaborated herein one by one.

[0108] In one embodiment, the control method includes the following steps:

[0109] Control the position detection device 5 to scan to obtain the orientation of the user;

[0110] When the controller receives the orientation information feedback by the position detection device 5, it controls the first driving component 3 and / or the second driving component 4 to drive the speaker body 2 to rotate relative to the mounting base 1, so that the speaker body 2 faces the direction where the user is located.

[0111] In this embodiment, after receiving the control instruction, the controller controls the position detection device 5 to scan to obtain the orientation of the user. It can be understood that the position detection device 5 can be structures such as an infrared sensor, a laser sensor, a displacement sensor, a radar, etc. Of course, the position detection device 5 can also be a communication module such as a Bluetooth detection module or a wifi module provided in the vehicle-mounted system 100, which is not limited herein.

[0112] It can be understood that after scanning the position of the user through the position detection device 5 and feeding back the position information to the controller, when the controller receives the orientation information feedback by the position detection device 5, it calculates the position and angle of the user relative to the speaker body 2, so as to control the rotation angle of the first driving component 3 and / or the second driving component 4 to drive the speaker body 2 to rotate relative to the mounting base 1, so that the speaker body 2 rotates to face the direction where the user is located.

[0113] In this embodiment, the controller is electrically connected to the second motor 41 of the second driving component 4 and the first motor 31 of the first driving component 3. After the orientation information of the user is scanned and confirmed by the position detection device 5, when the controller receives the orientation information feedback by the position detection device 5, the controller controls the second motor 41 of the second driving component 4 to drive the second rotating shaft 42 to drive the speaker body 2 to rotate a preset angle around the axial direction of the second rotating shaft 42, and then controls the first motor 31 of the first driving component 3 to drive the speaker body 2 to rotate a preset angle around the first rotating shaft 32 to realize swinging, so as to adjust the sound outlet 213 to face the user exactly, so as to realize the active form of listening experience optimization.

[0114] It can be understood that the rotation angle and / or swing angle of the speaker body 2 can be calculated based on the orientation information fed back by the position detection device 5. In this embodiment, to adjust the position of the sound outlet 213 to face the user's direction, it can be achieved by controlling the second motor 41 of the second driving component 4 to drive the second rotating shaft 42 to drive the speaker body 2 to rotate around the axial direction of the second rotating shaft 42; it can also be achieved by controlling the first motor 31 of the first driving component 3 to drive the speaker body 2 to rotate around the first rotating shaft 32; of course, it can also be achieved by first controlling the second motor 41 of the second driving component 4 to drive the second rotating shaft 42 to drive the speaker body 2 to rotate around the axial direction of the second rotating shaft 42 by a preset angle, and then controlling the first motor 31 of the first driving component 3 to drive the speaker body 2 to rotate around the first rotating shaft 32 by a preset angle; or first controlling the first motor 31 of the first driving component 3 to drive the speaker body 2 to rotate around the first rotating shaft 32 by a preset angle, and then controlling the second motor 41 of the second driving component 4 to drive the second rotating shaft 42 to drive the speaker body 2 to rotate around the axial direction of the second rotating shaft 42 by a preset angle.

[0115] Of course, the controller can also be arranged on the vehicle body, and the vehicle-mounted system 100 is applied to the vehicle body. This control structure can make the second motor 41 of the second driving component 4 and the first motor 31 of the first driving component 3 of the vehicle-mounted system 100 work.

[0121] In one embodiment, the angle by which the second driving component 4 drives the speaker body 2 to rotate about the axial direction of the rotation hole 12 of the mounting base 1 is θ1; where 0° < θ1 < 180°; or, 10° ≤ θ1 ≤ 150°; or, 20° ≤ θ1 ≤ 120°; or, 30° ≤ θ1 ≤ 120°; or, 60° ≤ θ1 ≤ 120°; or, 60° ≤ θ1 ≤ 90°.

The second driving component 4 drives the speaker body 2 to rotate about the axial direction of the rotation hole 12. At this time, the axial direction of the rotation hole 12 is perpendicular to the mounting surface.

[0123] It can be understood that the angle by which the second driving component 4 drives the speaker body 2 to rotate about the axial direction of the rotation hole 12 is defined as θ1, and the optional range of the rotation angle θ1 of the speaker body 2 is 0° to 360°. To ensure that after the vehicle-mounted system 100 is applied to the vehicle body, the vehicle-mounted system 100 is installed on the center console of the vehicle body and always faces the user direction, the optional range of the rotation angle θ1 of the speaker body 2 is 0° to 180°.

[0126] In this embodiment, as Figure 9 and Figure 10 shown, the swinging direction of the first driving component 3 driving the speaker body 2 is such that the plane formed by the swinging direction of the speaker body 2 is perpendicular to the mounting surface of the mounting base 1, that is, the plane formed by the swinging direction of the speaker body 2 is coplanar or parallel to the axial direction of the rotation hole 12.

[0127] It is understandable that the angle θ2 by which the first driving component 3 drives the speaker body 2 to swing is defined, and the optional range of the angle θ2 by which the speaker body 2 swings is 0° to 180°. To ensure that after the in-vehicle speaker 100 is applied to the vehicle body, when the in-vehicle speaker 100 is installed on the center console of the vehicle body, the speaker body 2 always faces the user direction, the optional range of the angle θ2 by which the speaker body 2 swings is 10° to 150°. Of course, the optional range of the angle θ2 by which the speaker body 2 swings can also be 20° to 120° or 30° to 120° or 60° to 120° or 10° to 60° or 10° to 30°.
