Description

Technical Field

[0001] This utility model relates to the technical field of vehicle audio systems, and more particularly to an audio housing, an audio system, and a vehicle. Background Technology

[0002] To enhance the premium and technological feel of car interiors and cater to higher consumer demands, a type of retractable car speaker has emerged. These speakers are typically mounted on the door panels or dashboard, retracting when not in use and extending outwards when the car is moving or music is played, a departure from the traditional hidden appearance of car speakers. When the car is started, the speaker rises with the rotating mechanism, and ambient lighting or background music can be added for enhancement; when the car is turned off, the speaker descends with the rotating mechanism, increasing the sense of technology and ceremony, making it particularly popular among young consumers.

[0003] However, the interior space of car door panels or dashboard panels is very compact, and there is not much space left after the original hidden speakers are installed. When modifying the original hidden speakers, it is even more difficult to leave enough space to install the rotating and lifting drive mechanism of the speakers. Therefore, the structural design of car lifting speakers needs to be very compact.

[0004] To meet installation space requirements, existing automotive lift speakers typically rely on complex transmission mechanisms to achieve the speaker's rotational and lifting motion. For example, Chinese Patent 201820535388.9 discloses a "telescopic horn device," which includes a base, a lifting drive mechanism, a speaker, magnetic components, and a Hall sensor. This solution, to reduce space occupation in the lifting direction, places the actuator on the side and uses a worm gear mechanism to drive the transmission wheel, thereby achieving speaker lifting via screw transmission. However, this lifting drive mechanism is structurally complex, with numerous transmission parts, and the transmission wheel participates in both the worm gear and lead screw transmissions, placing high demands on its axial positioning accuracy and overall assembly quality. Furthermore, this screw transmission method still occupies a significant amount of space. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a speaker housing, a speaker system, and a vehicle, solving the problems of complex structures and large space occupation of existing lifting speaker housings.

[0006] One embodiment of this utility model provides a speaker housing, comprising: a housing, a base, a power component, a top support, a connector, and a grille, wherein... The base is fixedly disposed within the housing, and the base has an audio mounting cavity inside; The power component is rotatably connected to the base with the vertical axis as the axis. The bottom of the power component is provided with a vertically extending gear ring. At least one end face of the power component is formed with a guide slope extending obliquely along the circumference of the gear ring. The top support is vertically slidably connected to the base, and the bottom of the top support is slidably connected to the guide slope. The connector is vertically slidably connected to the power component, the bottom of the connector is rotatably connected to the top of the top support component, and the top of the connector is fixedly connected to the mesh cover.

[0007] The technical solution disclosed in this utility model has at least the following beneficial effects: With the above structure, when in use, the motor drives the meshing gear ring and power component to rotate. Driven by the guide slope of the power component and the vertical guide of the base, the top support is forced to slide vertically, thereby driving the connecting part and the net cover to rise or fall. Since the power component is also vertically slidably connected to the connecting component, during the above-mentioned movement, the rotation of the power component will cause the connecting component to rotate together with the power component at the top of the top support component.

[0008] In summary, this speaker housing can simultaneously rotate and raise the grille. Compared with existing technologies, the number of parts used is greatly reduced, and there is no need to use threaded screws and worm gears for precise matching. This reduces the complexity of the structure and also reduces the overall size of the device.

[0009] In one embodiment of this utility model, a speaker housing is provided, wherein the power component includes a rotating part and a transmission part, wherein, The rotating part is rotatably connected to the base with the vertical axis as the axis.

[0010] The technical solution disclosed in this utility model has at least the following beneficial effects: By incorporating a rotating part and a transmission part, the complexity of the power components is reduced, facilitating subsequent processing and manufacturing. Furthermore, in this structure, the rotating part is only used to directly drive the connecting parts and the lifting of the mesh cover, while the transmission part drives the connecting parts and the mesh cover to rotate, thus separating the rotational transmission and lifting transmission of the device and facilitating subsequent functional expansion.

[0011] In one embodiment of the present invention, a speaker housing is provided, wherein the transmission part is a sliding sleeve, one end of the sliding sleeve is fixedly connected to the rotating part, and the other end of the sliding sleeve is vertically slidably connected to the connector through a keyway.

[0012] The technical solution disclosed in this utility model has at least the following beneficial effects: In use, the rotating part rotates, which drives the sliding sleeve to rotate. At the same time, the keyway at the other end of the sliding sleeve drives the connecting part to rotate together. Under the vertical drive of the top support, the connecting part moves vertically along the keyway at the other end of the sliding sleeve. By setting up the sliding sleeve, the transmission is completed, and the stability and reliability of the overall structure are also increased.

[0013] In one embodiment of the present invention, a speaker housing is provided, wherein the transmission part is a telescopic rod, one end of the telescopic rod is fixedly connected to the rotating part, and the other end of the telescopic rod is fixedly connected to the connecting member.

[0016] The technical solution disclosed in this utility model has at least the following beneficial effects: By utilizing the first elastic element, the power element and the top support element can be pulled together, making the overall structure more stable and reliable.

[0017] In one embodiment of the present invention, a speaker housing is provided, wherein a groove or slider extending in the same direction as the guide slope is provided, and the bottom of the top support is slidably connected to the guide slope through the groove or slider.

[0018] The technical solution disclosed in this utility model has at least the following beneficial effects: By leaving grooves or sliders on the guide ramp, the reliability of the connection between the top support and the power component can be enhanced.

[0019] In one embodiment of the present invention, a speaker housing is provided in which the bottom of the connector is also vertically elastically connected to the top of the top support.

[0020] The technical solution disclosed in this utility model has at least the following beneficial effects: In this structure, even if the mesh cover is subjected to downward pressure by an external force during its ascent or descent, the vertical elastic connection can offset the external force, allowing the connecting piece to move vertically together with the mesh cover, thereby dissipating the external force and preventing the transmission structure of this device from directly colliding with the external force, which could damage the corresponding parts.

[0027] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0028] This utility model provides a speaker housing, please refer to [the following text is in conjunction with the previous one]. Figure 1 and Figure 2 As shown, it includes: a shell 1, a base 2, a power component 3, a top support 4, a connecting component 5, and a mesh cover 6, wherein, The base 2 is fixedly installed inside the housing 1. The shape of the housing 1 and the installation limiting structure can be designed according to the space available in different vehicle models. Figure 1 The shape of the housing 1 shown is designed to fit one of the vehicle models, and there are no restrictions on the shape and structure here; Please refer to this section. Figure 5As shown, the base 2 has a speaker mounting cavity 201 inside for placing a speaker. The speaker can be fixedly mounted on the housing 1 or on the base 2. To improve the user experience, the speaker can also be connected to the top support 4 so that it moves vertically with the top support 4, or the speaker can be connected to the connector 5 so that it rotates and rises with the connector 5. The power component 3 is rotatably connected to the base 2 with the vertical axis as the axis. It should be understood that the vertical direction referred to in this application is the up and down direction of each figure, and also the direction perpendicular to the end face of the mesh cover 6 in each figure. The bottom of the power component 3 is provided with a vertically extending gear ring 3011, and at least one end face (specifically the upper end face) of the power component 3 is formed with a guide slope 3012 that extends obliquely along the circumference of the gear ring 3011. The specific shape of the guide slope 3012 is shown in the figure. Figure 3 As shown, it has at least one arc-shaped protrusion extending obliquely along the circumference of the gear ring 3011. In this embodiment, to increase the stability of the device during operation, two arc-shaped protrusions are provided and are symmetrically distributed. The top support 4 is vertically slidably connected to the base 2. Please refer to [reference needed]. Figure 3 ,as well as Figure 7 or Figure 8 As shown, the inner wall surface of the top support 4 is provided with a plurality of vertically extending vertical slide rails 404. In this embodiment, there are 3 vertical slide rails 404. Each vertical slide rail 404 is slidably connected to each vertical slide groove 203 on the base 2, thereby realizing the vertical guidance of the base 2 to the top support 4. The bottom of the top support 4 is slidably connected to / in contact with the guide slope 3012. The bottom end face of the top support 4 and the guide slope 3012 forms the top support slope 401. The top support slope 401 is configured to fit the guide slope 3012. With this configuration, when the power component 3 rotates, the top support 4 can be raised and lowered by the thrust of the guide slope 3012 and the guiding action of the vertical slide groove 203 of the base 2. When the device is not in use, that is, when the mesh cover 6, the connecting piece 5 and the top support 4 are lowered to the lowest point, the bottom end face of the top support 4 fits the guide slope 3012, so that the device is balanced by force. Even if it is stored for a long time without use or is affected by external force, it is not easy to be damaged. Of course, two symmetrically distributed sliders can also be provided on the bottom end face of the top support 4, and the sliding connection / contact between the top support 4 and the guide slope 3012 can be achieved through the sliders; The connector 5 is vertically slidably connected to the power component 3, the bottom of the connector 5 is rotatably connected to the top of the top support component 4, and the top of the connector 5 is fixedly connected to the mesh cover 6.

[0029] With the above structure, when in use, the motor 7 drives the meshing gear ring 3011 and the power component 3 to rotate. Driven by the guide slope 3012 of the power component 3 and guided by the vertical slide groove 203 of the base 2, the top support 4 is forced to slide vertically, thereby driving the connecting part 5 and the net cover 6 to rise or fall. Since the power component 3 is also vertically slidably connected to the connecting component 5, during the above-mentioned movement, the rotation of the power component 3 will cause the connecting component 5 to rotate together with the power component 3 at the top of the top support component 4.

[0030] In summary, this speaker housing can simultaneously rotate and lift the grille 6. Compared with existing technologies, the number of parts used is greatly reduced, and there is no need to use threaded screws and worm gears for precise matching. This reduces the complexity of the structure and also reduces the overall size of the device.

[0031] In another embodiment of this utility model, to facilitate processing and subsequent parts repair and replacement, this embodiment differs from the above embodiment in that the original power component 3 is split into two parts: a rotating part 301 and a transmission part 302. Please refer to this section. Figure 3 As shown, the rotating part 301 is rotatably connected to the base 2 with the vertical axis as the axis. The gear ring 3011 is disposed at one end of the rotating part 301, and the other end of the rotating part 301 has a guide slope 3012 that extends obliquely along the circumference of the gear ring 3011. One end of the transmission part 302 is disposed on the rotating part 301 to rotate with the rotating part 301, and the other end of the transmission part 302 is connected to the connector 5. The rotating part 301 is vertically slidably connected to the connector 5 through the transmission part 302.

[0032] By setting up the rotating part 301 and the transmission part 302, on the one hand, the complexity of the power component 3 is reduced, which facilitates subsequent processing and manufacturing. On the other hand, in this structure, the rotating part 301 is only used to directly drive the connecting part 5 and the mesh cover 6 to lift, while the transmission part 302 drives the connecting part 5 and the mesh cover 6 to rotate, so that the rotation transmission and lifting transmission of the device are separated, which facilitates subsequent functional expansion.

[0033] There are multiple ways to implement the transmission unit 302. This embodiment will illustrate the following two implementation methods as examples: Firstly, please refer to this section. Figure 3 , Figure 5 and Figure 6The transmission part 302 is a sliding sleeve, one end of which is fixedly connected to the rotating part 301. This fixed connection can be in various ways, such as by snap-fit ​​or bolt fixing. In this embodiment, in order to facilitate installation and reduce structural complexity, multiple vertically extending downwardly penetrating limiting strips 3013 are provided on the outer ring surface of the rotating part 301. At the same time, at the bottom of the inner wall surface of the sliding sleeve, a limiting groove 3021 corresponding to the limiting strips 3013 is provided, and the two are interference fit. During installation, the vertical limiting groove 3021 of the sliding sleeve is aligned with the limiting strips 3013, and then inserted downward and pressed to complete the installation. No additional fixed connection structure is required, making it more convenient to use. Please combine here Figure 4 As shown, the other end of the sliding sleeve has an upward through keyway 3022, and the bottom of the connector 5 is provided with a vertically extending guide key 502. Through the cooperation of the keyway 3022 and the guide key 502, the sliding sleeve and the connector 5 can be vertically slidably connected.

[0034] With the above structure, the rotation of the rotating part 301 can drive the sliding sleeve to rotate. At the same time, the keyway 3022 at the other end of the sliding sleeve drives the connecting part 5 to rotate together. Meanwhile, under the vertical drive of the top support 4, the connecting part 5 moves vertically along the keyway 3022 at the other end of the sliding sleeve. By setting the sliding sleeve, the transmission can be completed while the stability and reliability of the overall structure can be increased.

[0035] Secondly, the transmission part 302 is a telescopic rod (not shown in the attached drawings of this embodiment). One end of the telescopic rod is fixedly connected to the rotating part 301, and the other end of the telescopic rod is fixedly connected to the connecting member 5.

[0036] In use, the rotating part 301 rotates to drive the telescopic rod to rotate. At the same time, the other end of the telescopic rod drives the connecting piece 5 to rotate together. Meanwhile, the connecting piece 5 moves vertically under the vertical drive of the top support 4. The telescopic rod can extend and retract vertically to avoid obstacles. By setting the telescopic rod, the space occupied by the overall device is further reduced while completing the transmission.

[0037] This utility model also provides another embodiment. To enhance the connection stability between the power component 3, specifically the rotating part 301 and the top support component 4, this embodiment provides a corresponding stability connection structure between the top support component 4 and the rotating part 301. The stability connection structure can be, for example, as follows: The first elastic element (not shown in the figure) is connected at both ends to the power element 3 and the top support element 4, respectively. The first elastic element can be a tension spring or a sheet spring. Using the first elastic element, the power element 3 and the top support element 4 can be pulled together, making the overall structure more stable and reliable.

[0038] The aforementioned stability connection structure can also be, for example, a groove or slider extending in the same direction as the guide slope 3012, with the bottom of the top support 4 slidably connected to the guide slope 3012 through the groove or slider.

[0039] By leaving grooves or sliders on the guide slope 3012, the connection reliability between the top support 4 and the power component 3 can be enhanced.

[0040] This utility model also provides another embodiment, which differs from the above embodiment in that the bottom of the connecting member 5 is also vertically elastically connected to the top of the top support member 4. In this structure, even if the mesh cover 6 is subjected to downward pressure by external force during the rising or falling process, the vertical elastic connection can offset the external force, allowing the connecting member 5 and the mesh cover 6 to move vertically together, thereby dissipating the external force and preventing the transmission structure of this device from directly colliding with the external force, thus damaging the corresponding parts.

[0041] To achieve the above-mentioned vertical flexible connection, please refer to the following: Figure 7 , Figure 8 as well as Figure 9 As shown, its specific structure includes: the connector 5 is sleeved on the top support 4, the inner ring surface of the connector 5 has a first step surface 501 extending radially therein, and the outer ring surface of the top support 4 has a second step surface 402 that is directly opposite to the first step surface 501. The speaker housing also includes a second elastic element 403, the two ends of which abut against the first stepped surface 501 and the second stepped surface 402, respectively. Specifically, the second elastic element 403 includes a spring 4031 (or a spring sheet) and a pressure relief ring 4032. (Refer to...) Figure 5 As shown, the pressure relief ring 4032 is vertically slidably connected to the top of the top support 4. The upper end face of the pressure relief ring 4032 abuts against the first step surface 501. The spring 4031 is sleeved on the top support 4, and one end of the spring 4031 abuts against the lower end face of the pressure relief ring 4032, while the other end of the spring 4031 abuts against the second step surface 402. The outer ring surface of the top support 4 also has a limiting member (not shown in the figure) to prevent the connector 5 from coming out.

[0042] With the above configuration, when the mesh cover 6 is subjected to downward pressure from an external force, the spring 4031 can be forced to deform vertically by the compression of the first step surface 501 and the second step surface 402, thereby providing clearance space for the mesh cover 6 and the connecting piece 5, and at the same time relieving the external force.

[0043] In summary, when using it, install motor 7 as follows: Figure 2At the motor connector 202 shown, the speaker is installed into the speaker mounting cavity 201 of the base 2. Then, the motor 7 drives the gear ring 3011 and the rotating part 301 that mesh with it to rotate. Driven by the guide slope 3012 at the top of the rotating part 301 and guided by the vertical slide groove 203 of the base 2, the top support 4 is forced to slide vertically, thereby driving the connector 5 and the mesh cover 6 to rise or fall. Since one end of the transmission part 302 is connected to the rotating part 301, and the other end of the transmission part 302 is also vertically slidably connected to the connecting member 5, during the above-mentioned movement, the rotation of the rotating part 301 will drive the transmission part 302 and the connecting member 5 to rotate together with the rotating part 301 on the top of the top support member 4.

[0044] When the mesh cover 6 is subjected to downward pressure from an external force, the spring 4031 is forced to deform vertically by the compression of the first step surface 501 and the second step surface 402, thereby providing clearance space for the mesh cover 6 and the connecting piece 5, and at the same time relieving the external force.

[0045] In summary, this speaker housing can simultaneously rotate and raise the grille 6, as well as provide force relief protection. Compared with existing technologies, the number of parts used is greatly reduced, and there is no need to use threaded screws and worm gears for precise matching, which reduces the complexity of the structure and also reduces the overall size of the device.
