[0043] This utility model proposes a sound-generating device.

[0044] Please see Figures 1 to 3In one embodiment of this utility model, the sound-generating device includes a housing 100 and a sound-generating module 200. The housing 100 forms a first receiving cavity 101, and the sound-generating module 200 is housed and installed within the first receiving cavity 101. Thus, the sound emitted by the sound-generating module 200 can propagate outside the housing 100, providing the user with a good auditory experience. The first housing 100 provides protection for the sound-generating module 200, preventing dust and foreign objects from entering the housing 100, thereby protecting the sound-generating module 200 from contamination or damage. It also provides some impact protection, improving the stability and lifespan of the sound-generating device in daily use. This sound-generating device can be installed in vehicles, airplanes, and other means of transportation, or applied to speaker systems in fixed locations such as homes and shopping malls. The sound-generating module 200 can be configured as a tweeter module to enhance the sound field and cooperate with other sound-generating devices in the environment to improve the acoustic effect.

[0045] The sound-generating device also includes a mounting component 300, an aromatherapy component 400, and a lifting mechanism 500. The top of the housing 100 has a first mounting opening 102 communicating with the first receiving cavity 101. The mounting component 300 is movably inserted through the first mounting opening 102 and forms a second receiving cavity 310 and a communicating hole 320 communicating with the second receiving cavity 310. At least the communicating hole 320 is exposed outside the housing 100. The aromatherapy component 400 is installed in the second receiving cavity 310. The lifting mechanism 500 is received and installed in the first receiving cavity 101 and is driven and connected to the mounting component 300. It should be noted that the definitions of top, bottom, and vertical directions are all based on the installed state of the sound-generating device.

[0046] In this way, the fragrance of the aromatherapy component 400 can diffuse from the connecting hole 320 and reach the space outside the housing 100, thus spreading in the current environment to provide users with a pleasant olfactory experience. Furthermore, the mounting component 300, while providing an installation environment and protection for the aromatherapy component 400, can also be raised and lowered by the lifting mechanism 500, providing users with a dynamic visual experience. Moreover, the raising and lowering of the mounting component 300 can change its height position, thereby adjusting the fragrance diffusion range. Specifically, when the connecting hole 320 is at a higher position, the fragrance diffuses more easily into a larger space; when the connecting hole 320 is at a lower position, the fragrance can be concentrated in a smaller area. That is, users can adjust the height position of the mounting component 300 by raising and lowering it via the lifting mechanism 500 according to the desired fragrance concentration.

[0047] Therefore, in this utility model, by combining the auditory experience provided by the sound-generating module 200, the olfactory experience provided by the aromatherapy component 400, and the visual experience brought about by the lifting and lowering of the mounting component 300, the sound-generating device can bring users a multi-dimensional sensory experience, which is conducive to enriching the user's experience.

[0048] In one scenario, the mounting component 300 is initially positioned lower, and when the sound playback function of the sound-emitting device is activated, the lifting mechanism 500 simultaneously drives the mounting component 300 to rise, thereby activating the aromatherapy function at the same time. Of course, the sound playback function and the aromatherapy function can also be activated independently.

[0049] In one embodiment, the housing 100 is configured as a house, including two roof slopes 103 that extend toward each other in an upward direction, and the first mounting opening 102 is provided on one of the roof slopes 103.

[0050] Thus, the sound-generating device can have a house-shaped appearance, making it not only a sound-generating device but also a decorative piece. Compared to ordinary sound-generating devices, the sound-generating device of this invention has a more unique appearance and can give people a warm feeling, which helps to further enhance the user's visual experience. At the same time, through the inclined setting of the roof slope 103, the space above the roof slope 103 can provide lifting space for the mounting component 300, so as to adjust the height of the connecting hole 320 on the mounting component. Of course, in other embodiments, the housing 100 can also be a box-shaped structure.

[0051] In one embodiment, the top sides of the two roof slopes 103 are joined together. This results in a simpler house shape, which simplifies the structure of the shell 100 and facilitates its fabrication. Alternatively, in other embodiments, a planar or curved structure may be provided between the top sides of the two roof slopes 103.

[0052] In one embodiment, the mounting component 300 is configured in a chimney shape. Specifically, the mounting component 300 is configured as a columnar structure with its axis extending vertically, which can be a cylinder or a polygonal prism, thus facilitating the processing and assembly of the mounting component 300. Furthermore, the chimney shape of the mounting component 300 can match the house shape of the housing 100, and the dynamic effect of the chimney rising and falling is also harmonious, thereby ensuring a good visual experience for the user. Of course, in other embodiments, the mounting component 300 can also be other shapes, such as a loft shape or a balloon shape.

[0053] In one embodiment, please refer to Figures 3 to 5The housing 100 also includes multiple wall portions 110, which surround and form the first receiving cavity 101. One of the wall portions 110 is a mesh protective plate 111. The sound-emitting surface of the sound-emitting module 200 faces the mesh protective plate 111. In this way, the sound from the sound-emitting module 200 can directly propagate outward through the mesh of the mesh protective plate 111, reducing sound reflection and loss inside the housing 100, helping to maintain the clarity and directionality of the sound, and allowing the mesh protective plate 111 to face the user to ensure the user's auditory experience. In other embodiments, the sound-emitting surface of the sound-emitting module 200 can also be arranged upward, with mesh holes provided at corresponding positions on the roof slope 103.

[0054] Furthermore, both of the aforementioned roof slopes 103 are connected to the mesh protective panel 111. It is understood that the mesh protective panel 111 will face the user, and the two roof slopes 103 will be distributed in the left-right direction, allowing the user to obtain a relatively complete visual experience from one side of the mesh protective panel 111. In other embodiments, the bottom side of one of the roof slopes 103 may also be connected to the mesh protective panel 111.

[0055] In one embodiment, please refer to Figure 4 and Figure 5 The mesh protective plate 111 has a second mounting opening 104 above the mesh area, and the sound-generating device also includes a decorative window 600 movably disposed in the second mounting opening 104.

[0056] In this way, the decorative window 600 can further enhance the details of the housing structure of the shell 100, and the dynamic rotation of the decorative window 600 provides users with a richer visual experience. In addition, after the decorative window 600 opens the second mounting port 104, it can provide more heat dissipation channels to improve the heat dissipation effect of the sound-generating device, thereby ensuring the sound-generating performance of the sound-generating device.

[0057] The decorative window 600 can be a plastic or metal structure. It can consist of a window body and a window frame surrounding the window body. Alternatively, it can have intersecting grooves formed on the surface of the decorative window 600 exposed outside the housing 100, thus creating the visual effect of multiple window panes.

[0058] In other embodiments, the decorative window 600 may be omitted, or the decorative window 600 may be fixedly installed. A curtain structure may be provided in the first receiving cavity 101, and a dynamic visual effect may be provided by pulling the curtain.

[0059] In one embodiment, please refer to Figure 3 and Figure 4The lifting mechanism 500 includes a drive device 510 and a lifting frame 520. The drive device 510 is driven and connected to the lifting frame 520. The mounting member 300 is fixedly installed on the lifting frame 520. The lifting frame 520 is capable of transmission and cooperation with the decorative window 600 so that the decorative window 600 has an initial position covering the second mounting opening 104 and an outward flipping position.

[0060] Please refer to Figure 1 When the decorative window 600 is in its initial position, the covering of the second mounting opening 104 provides excellent waterproofing and dustproofing. When it is switched to the operating position, please refer to... Figure 2 The first receiving cavity 101 can be connected to the space outside the housing 100 through the second mounting port 104, thereby providing a new heat dissipation channel.

[0061] In this embodiment, when the lifting frame 520 is raised or lowered, it can drive the fixedly installed mounting component 300 to rise or fall synchronously. At the same time, it can transmit power to the decorative window 600, so that the decorative window 600 can switch between the initial position and the operating position. In this way, the lifting mechanism 500 can simultaneously drive the mounting component 300 to rise or fall and drive the decorative window 600 to rotate, which helps to simplify the structure of the sound-generating device, thereby reducing the space requirements of the first receiving cavity 101. Furthermore, the mounting component 300, which has the appearance of a chimney, and the decorative window 600 can move synchronously, providing users with a richer visual experience.

[0062] In other embodiments, a different driving structure can be set to drive the decorative window 600 to flip, or the user can manually pull the decorative window 600.

[0063] Further, please refer to Figure 3 and Figure 4 A guide post 130 is erected within the first receiving cavity 101. The lifting frame 520 includes a driving sleeve 522 and a guide sleeve 523 extending in parallel. The guide sleeve 523 is fitted onto the guide post 130 to provide guidance. The driving sleeve 522 is fitted onto the drive shaft of the driving device 510 and is engaged with it via a ball screw structure. The driving device 510 is configured as a rotary motor, thereby enabling the lifting frame 520 to rise and fall smoothly through the rotation of the drive shaft. Multiple sets of guide posts 130 and guide sleeves 523 can be provided, preferably two sets, with the two sets of guide posts 130 and guide sleeves 523 distributed on the horizontal sides of the driving sleeve 522. Of course, in other embodiments, the driving device 510 can also be configured as a cylinder, with the output shaft 511 fixedly connected to the lifting frame 520.

[0064] Further, please refer to Figure 1 and Figure 2Multiple decorative windows 600 are provided, and the lifting frame 520 simultaneously drives multiple decorative windows 600 to rotate. Taking two decorative windows 600 as an example, the two decorative windows 600 can be set opposite to the two roof slopes 103 respectively. Of course, the number of decorative windows 600 can also be one, preferably set in the center.

[0065] In one embodiment, please refer to Figures 7 to 9 The upper side of the decorative window 600 is rotatably connected to the housing 100, and the lower side of the decorative window 600 is provided with a pushing slope 610. The pushing slope 610 extends obliquely in the upward direction toward the first receiving cavity 101. The lifting frame 520 is provided with a pushing part 521, which is located below the pushing slope 610. Thus, when the lifting frame 520 rises, it can push the pushing slope 610 through the pushing part 521, thereby driving the decorative window 600 to flip outward and reach the operating position. When the lifting frame 520 descends, under the action of gravity, the decorative window 600 will swing inward and return to its initial position. Of course, in other embodiments, the decorative window 600 may also be rotatably connected to the housing 100 on one side in the horizontal direction.

[0066] In one embodiment, please refer to Figures 7 to 9 The decorative window 600 is also provided with a positioning groove 620, which is connected to the upper side of the pushing inclined surface 610 for the pushing part 521 to engage, so that the decorative window 600 can be maintained in the operating position. It can be understood that, as Figure 9 As shown, when the lifting frame 520 rises to its limit position, the pushing part 521 will also slide to the upper side of the pushing slope 610, thereby engaging with the positioning groove 620. Through the adaptive engagement of the pushing part 521 and the positioning groove 620, the weight of the decorative window 600 is counteracted, allowing the decorative window 600 to be more stably maintained in its outward-flipping position. Furthermore, the opening degree of the decorative window 600 in its operating position can be controlled by changing the orientation of the positioning groove 620 to meet visual experience or heat dissipation requirements. In other embodiments, the decorative window 600 can also be pushed outward by the abutting engagement of the pushing part 521 and the pushing slope 610.

[0067] In one embodiment, please refer to Figure 6The aromatherapy component 400 includes an aromatherapy liquid carrier 410 and a vibrating plate 420. The vibrating plate 420 is disposed above the aromatherapy liquid carrier 410, and the connecting hole 320 is disposed on the top of the mounting component 300 and spaced apart from the vibrating plate 420. Specifically, the aromatherapy liquid carrier 410 can be a porous component such as a cotton swab or a sponge. The aromatherapy liquid is absorbed by the aromatherapy liquid carrier 410, and the vibration of the vibrating plate 420 causes the aromatherapy liquid to evaporate and diffuse to the outside of the housing 100 through the connecting hole 320. A circuit board can be disposed in the first receiving cavity 101. The driving device 510 and the vibrating plate 420 are electrically connected to the circuit board. The electrical connection structure between the vibrating plate 420 and the circuit board should have a certain margin to avoid interfering with the lifting and lowering of the mounting component 300. In other embodiments, the aromatherapy component 400 may also include an aromatherapy candle and a lamp mounted on the mounting member 300, wherein the heat generated by the light emitted by the lamp melts the aromatherapy candle. Alternatively, the aromatherapy liquid may be directly poured into the mounting member 300, and the inner wall of the mounting member 300 is provided with a heating wire, which heats the aromatherapy liquid to release the fragrance.

[0068] In one embodiment, please refer to Figure 1 The housing 100 includes a mounting plate 120 at the bottom, the mounting plate 120 having a fastening hole 121 located outside the first receiving cavity 101. Thus, fasteners can pass through the fastening hole 121 to fix the mounting plate 120 and other base structures, achieving a fixed installation of the sound-generating device. The sound-generating device can be connected to a mounting bracket or a vehicle dashboard, etc., using fasteners. In other embodiments, the sound-generating device can also be placed on a table for use.

[0069] This utility model also proposes an audio system, which includes a sound-generating device. The specific structure of the sound-generating device is as described in the above embodiments. Since this audio system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0070] This utility model also proposes a vehicle including a sound-generating device. The specific structure of the sound-generating device is as described in the above embodiments. Since this vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here. After the user enters the vehicle, the lifting mechanism 500 can be activated, driving the mounting component 300 to rise and the decorative window 600 to rotate outwards. Simultaneously, the aromatherapy component 400 starts working, providing the user with a dynamic visual experience and a fragrant olfactory experience, thereby providing the user with a good sense of interaction and driving atmosphere. The movement of the mounting component 300 and the decorative window 600 can be completed in a short time, within ten seconds or half a minute. The aromatherapy component 400 can work continuously, stopping when it detects that a certain concentration has been reached inside the vehicle.

[0071] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model.
