[0059] In addition, in the present invention, descriptions such as "first", "second", etc. are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0060] 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, a CD player, a DVD player, a video recorder, etc.) to form a complete audio combination.

[0061] In the related art, in-vehicle systems are generally set to be fixed inside the vehicle body and are front speakers located on both sides of the front doors of the vehicle. However, the listening environment in a 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 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 in-vehicle console, and the sound emitted is upward and cannot be directed towards the listeners, resulting in a poor surround sound playback effect.

[0062] Based on the above concepts and problems, the present invention proposes an in-vehicle system 100. It can be understood that the in-vehicle system 100 is applied to a vehicle and is used as the speaker device of the vehicle. In this embodiment, the in-vehicle system 100 is installed on structures such as the in-vehicle console, which is not limited herein.

[0063] Please refer to Figures 1 to 10As 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 radar assembly, and a controller. Among them, the mounting base 1 is provided with a mounting cavity 11 and a rotating 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 also 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 arranged in the receiving cavity 211 and is connected to the speaker body 2. The second driving component 4 is arranged in the mounting cavity 11. Part of the second driving component 4 sequentially passes through the rotating hole 12 and the activity hole 212 and extends into the receiving cavity 211 and is connected to the first driving component 3. The radar assembly includes a first radar 5 and a second radar 6. The first radar 5 is arranged on the mounting base 1, and the second radar 6 is arranged on the speaker body 2. The controller is electrically connected to the first radar 5, the second radar 6, the first driving component 3, and the second driving component 4.

[0064] 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 radar assembly, and the controller. That is, the mounting base 1 provides an installation foundation for structures such as the speaker body 2, the driving mechanism, the radar assembly, 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.

[0065] 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, which are not limited here.

[0066] 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 structures such as the speaker body 2 to be located outside the mounting cavity 11 of the mounting base 1, the mounting base 1 is also provided with a rotating hole 12 communicating with the mounting cavity 11. Optionally, the outer contour of the rotating hole 12 can be a circular, elliptical, square, triangular, polygonal, or special-shaped structure, etc., which is not limited here.

[0067] Optionally, the speaker body 2 can be a speaker or a speaker structure or a horn structure, etc., which is not limited here. In this embodiment, the speaker body 2 is provided with a receiving 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, on the side of the speaker body 2 facing the mounting base 1, there is also an activity hole 212 communicating with the receiving cavity 211. It can be understood that the activity hole 212 provides an avoidance space for the second driving component 4.

[0068] 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 surrounding sound listening effect, thereby realizing the optimization of the listening experience in an active form 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 installation cavity 11. Part of the second driving component 4 sequentially passes through the rotation hole 12 and the moving hole 212 and extends into the cavity 211, and is connected to the first driving component 3.

[0069] It can be understood that by setting the radar component and the controller, the controller is electrically connected to the first radar 5, the second radar 6, the first driving component 3 and the second driving component 4 of the radar component. Thus, the first radar 5 and the second radar 6 of the radar component are used to detect the position of the user, and the detection signal is fed back 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 drives the speaker body 2 to swing, so that the second driving component 4 moves relative to the moving hole 212 and along the extension direction of the moving 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, realizing turning the speaker body 2 to the direction facing the user to improve the user's auditory feeling.

[0070] It should be noted that the first radar 5 is arranged on the installation base 1, and the second radar 6 is arranged on the speaker body 2. Thus, the position of the user can be initially scanned by the first radar 5. After receiving the initial position information fed back by the first radar 5, 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 drives the speaker body 2 to swing, so that the second driving component 4 moves relative to the moving hole 212 and along the extension direction of the moving hole 212, making the speaker body 2 face the general position of the user; then the position of the user is further scanned by the second radar 6, so as to further confirm the position direction of the user through the second radar 6, so that 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 drives the speaker body 2 to swing, so that the second driving component 4 moves relative to the moving hole 212 and along the extension direction of the moving hole 212, realizing the precise adjustment of the rotation direction of the speaker body 2.

[0071] In this embodiment, the second driving component 4 provides driving force for the rotation of the entire speaker body 2. Optionally, the second driving component 4 may be a structure such as a rotary motor or a rotary cylinder, as long as it can drive the speaker body 2 to rotate circumferentially in a 360° direction, and there is no limitation here. It can be understood that the first driving component 3 provides driving force for the swinging of the speaker body 2. Optionally, the first driving component 3 may be a swinging motor or a swinging cylinder or a structure that can drive the speaker body 2 to swing, and there is no limitation here.

[0072] It can be understood that the movable hole 212 not only provides an avoidance space for the second driving component 4, but also when the speaker body 2 swings relative to the second driving component 4, the second driving component 4 moves relative to the speaker body 2 within the movable hole 212. Optionally, the aperture or opening area of the movable hole 212 is much larger than the cross-sectional area of the second driving component 4 passing through the movable hole 212.

[0073] Optionally, the movable hole 212 is arranged as a strip-shaped hole or a waist-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.

[0074] In this embodiment, the radar component includes a first radar 5 and a second radar 6. The first radar 5 is arranged on the mounting base 1, and the second radar 6 is arranged on the speaker body 2 to detect the position of the user by using the first radar 5 and the second radar 6 respectively. It can be understood that the controller may be a control structure arranged in the vehicle-mounted system 100, such as a control circuit or a control panel or other control structures, and there is no limitation here. Of course, the controller may also be a control system or a control circuit or a control panel of the vehicle body, etc., and there is no limitation here.

[0075] Optionally, the first radar 5 and the second radar 6 may be structures such as infrared sensors, laser sensors, displacement sensors, radars, etc. Of course, the first radar 5 and the second radar 6 may also be communication modules such as a Bluetooth detection module or a wifi module arranged in the vehicle-mounted system 100, and there is no limitation here.

[0076] The in-vehicle system 100 of the present invention is provided with a first driving component 3 in the cavity 211 of the speaker body 2, so that the first driving component 3 is connected to the speaker body 2. By providing an installation cavity 11 in the installation base 1, the second driving component 4 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 provided on the installation base 1, and a movable hole 212 communicating with the cavity 211 is provided on one side of the speaker body 2 facing the installation base 1. Thus, part of the second driving component 4 can conveniently pass through the rotation hole 12 and the movable hole 212 in sequence 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 installation 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 installation 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 speaker body 2 driven by the second driving component 4 is different from the swinging direction of the speaker body 2 driven by the first driving component 3. Thus, 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 in-vehicle system 100 realizes a surround sound effect, thereby realizing an active form of sound perception optimization and effectively improving the user experience; further, by providing a first radar 5 on the installation base 1 and a second radar 6 on the speaker body 2, the position of the user can be initially scanned and located by using the first radar 5, 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 user, and then the position of the user is further scanned and located by using the second radar 6, realizing a visual experience centered on the user, giving the user a relatively obvious sense of ceremony, effectively improving the user experience, and at the same time improving the rotation accuracy.

[0077] In one embodiment, the speaker body 2 includes a housing 21 and a speaker. Among them, the housing 21 is provided with a cavity 211, a movable hole 212 and a sound outlet hole 213 communicating with the cavity 211. The first radar 5 is provided on the housing 21 and is arranged adjacent to the sound outlet hole 213. The speaker is provided in the cavity 211 and is arranged corresponding to the sound outlet hole 213.

[0078] In this embodiment, as Figures 1 to 10 shown, the housing 21 is used to protect and install and fix the speaker and the first driving component 3. It can be understood that the housing 21 has a hollow cavity, that is, a cavity 211 is formed inside the housing 21. It can be understood that by providing the sound outlet hole 213 on the housing 21, the speaker is provided in the cavity 211 and is arranged corresponding to the sound outlet hole 213. Thus, while the housing 21 protects the speaker, the sound emitted by the speaker is smoothly transmitted to the outside through the sound outlet hole 213.

[0079] Optionally, as Figures 1 to 5 、Figures 7 to 10 As shown, the sound outlet holes 213 include multiple ones; the multiple sound outlet holes 213 surround the second radar 6; or, the multiple sound outlet holes 213 are arranged radially with the second radar 6 as the center. It can be understood that with such an arrangement, the sound output effect of the speaker body 2 can be ensured.

[0080] In one embodiment, the housing 21 includes a front housing 214 and a rear housing 215. The front housing 214 and the rear housing 215 are connected and enclose to form a cavity 211. The movable hole 212 is provided on one side of the front housing 214 and / or the rear housing 215 facing the mounting base 1, and the sound outlet holes 213 and the second radar 6 are provided on the side of the front housing 214 facing away from the rear housing 215.

[0081] In this embodiment, as Figure 2 and Figure 4 shown, by setting the housing 21 of the speaker body 2 as the front housing 214 and the rear housing 215, the front housing 214 and the rear housing 215 are connected and enclose to form a cavity 211, so as to install and fix the first driving component 3 and other components by using the cavity 211 formed by the enclosure of the front housing 214 and the rear housing 215. Optionally, the front housing 214 and the rear housing 215 are detachably connected, such as by snap connection, plug-in fit, screw connection or pin connection, etc., so as to improve the installation convenience of the first driving component 3 and other components.

[0082] In this embodiment, the front housing 214 of the housing 21 of the speaker body 2 is the side facing the user, and the rear housing 215 is the side facing away from the user. By setting the second radar 6 on the front housing 214 of the speaker body 2, it is convenient to use the second radar 6 to detect or scan the position of the user, and it is convenient to locate the position of the user faster.

[0083] 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 arranged 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.
