Description

Technical Field

[0001] This application relates to the field of loudspeaker technology, and more particularly to a loudspeaker device. Background Technology

[0002] White noise refers to a sound whose frequency components have a uniform power spectral density across the entire audible range (20–20000 Hz). White noise is widely recognized as an effective "sound cosmetic" treatment for neurological disorders such as distractibility, tinnitus, hyperacusis, and ADHD. Some people also use white noise to weaken sounds that disrupt their sleep. Therefore, white noise lamps have emerged. A white noise lamp is a table lamp that emits white noise, typically placed by the bedside, providing both illumination and a sleep-inducing effect.

[0003] Existing white noise lamps mainly consist of a lighting module and a speaker module. To achieve good sound quality, the rear acoustic chamber of the speaker module needs to be well-sealed. In related technologies, existing white noise lamps require specialized structural components to create a sealed rear acoustic chamber behind the speaker module in the sound output direction, thus making the overall structure of existing white noise lamps quite complex. Utility Model Content

[0004] In view of this, this application provides a speaker device to improve the technical problem that existing speaker devices with other functions, such as white noise lamps, require more structural components to form a sealed rear sound cavity behind the speaker module in the sound output direction, which makes the overall structure of existing white noise lamps more complicated.

[0013] Alternatively, at least a portion of the light source device may be located outside the first housing.

[0014] Optionally, in some embodiments of this application, the light source device is disposed on one side surface of the circuit board, and the side surface of the circuit board on which the light source device is disposed directly or through a first elastic gasket abuts against the edge of the second opening to seal the second opening.

[0015] Optionally, in some embodiments of this application, the outer periphery of the circuit board is sealed to the inside of the second opening to seal the second opening.

[0016] Optionally, in some embodiments of this application, at least one assembly positioning structure is further provided between the first housing and the functional module.

[0017] Optionally, in some embodiments of this application, the assembly positioning structure includes a positioning post and a positioning hole that fit together, one of the positioning post and the positioning hole being disposed on the first housing, and the other of the positioning post and the positioning hole being disposed on the functional module.

[0018] Optionally, in some embodiments of this application, the speaker module includes a speaker component and a module bracket. The module bracket is disposed at the first opening and recessed toward the inner side of the first housing. The speaker component is mounted on the module bracket and completely covers the first opening.

[0019] Optionally, in some embodiments of this application, the periphery of the module bracket is fastened to the edge of the first opening, or the periphery of the module bracket is integrally connected to the edge of the first opening.

[0020] Optionally, in some embodiments of this application, the speaker component is fastened to the module bracket by a screw structure or a snap-fit ​​structure.

[0021] Optionally, in some embodiments of this application, the housing assembly further includes a second housing disposed around the outer peripheral side of the first housing, and the second housing has a third opening with the same opening orientation as the first opening;

[0022] The second housing is fastened to the first housing, and the edge of the third opening directly or through the second elastic pad abuts against one side surface of the speaker module to press and fix the speaker module onto the first housing.

[0023] Optionally, in some embodiments of this application, the housing assembly further includes a first cover having a sound outlet, the first cover covering the third opening.

[0028] The speaker device provided in this application, through the aforementioned structural arrangement, allows for the provision of additional functional modules such as lighting and aromatherapy, in addition to a conventional speaker module. This is achieved by mounting the speaker module at the first opening of the first housing, sealing the first opening, and oriented the speaker module's sound output direction towards the outside of the first housing. When the functional module is mounted at the second opening of the first housing, also sealed, the first housing and the functional module together form the rear acoustic cavity of the speaker module. This sealing effect of the rear acoustic cavity of the speaker module is ensured solely through the sealing cooperation between the first housing and the functional module. Thus, this speaker device effectively combines the speaker module and the functional module, saving on structural components for sealing the rear acoustic cavity of the speaker module, making the overall structure of the speaker device simpler and more compact. It is evident that this technical solution can effectively improve the existing technical problem that existing speaker devices with other functions, such as white noise lamps, require more structural components to form a sealed rear sound cavity behind the speaker module in the direction of sound output, which makes the overall structure of existing white noise lamps more complex.

[0039] To better understand and implement this application, the technical solutions in this application will be clearly and completely described below with reference to the accompanying drawings.

[0040] In the description of this application, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0042] In one embodiment, see Figures 1 to 6 This application provides a speaker device 1, which mainly includes a housing assembly 10, a speaker module 20, and a functional module 30. Specifically, the housing assembly 10 may include a first housing 11, which has a first opening 111 and a second opening 112. The speaker module 20 is specifically installed in the first opening 111, and the first opening 111 is sealed. The sound output direction of the speaker module 20 faces outward from the first housing 11. The functional module 30 is specifically installed in the second opening 112, and the second opening 112 is sealed, so that the first housing 11 and the functional module 30 together form a rear sound cavity 23 for the speaker module 20.

[0043] It should be noted that the speaker device 1 in this application embodiment is mainly applied to devices that have both conventional speaker functions and other functions such as lighting and aromatherapy. For example, it can be a device such as a white noise lamp that can be used for both light-assisted sleep and playing white noise, music, broadcasts, etc. In this case, when the speaker device 1 is specifically a white noise lamp, its speaker module 20 can play white noise when it is working. The aforementioned functional module 30 can specifically be a light source module to provide light-assisted sleep. The aforementioned speaker module 20 being installed in the first opening 111 and making the first opening 111 sealed specifically means that after the speaker module 20 is installed in the first opening 111 through a detachable structure such as a snap-fit ​​structure, screw structure, or abutment, the speaker module 20 can completely close the first opening 111. Similarly, the aforementioned functional module 30 being installed in the second opening 112 and making the second opening 112 a sealed arrangement specifically means that after the functional module 30 is installed in the second opening 112 through a detachable structure such as a snap-fit ​​structure, screw structure, or abutment, the functional module 30 can completely close the first opening 111. The aforementioned sound output direction of the speaker module 20 facing the outside of the first housing 11 specifically means that when the speaker module 20 is installed in the first opening 111, the side of the speaker module 20 containing the cone or diaphragm is located on the outside of the first housing 11, while the other side of the speaker module 20 away from the cone or diaphragm is located on the inside of the first housing 11. In this way, the first housing 11 is located behind the speaker module 20 in the sound output direction.

[0044] In addition, the aforementioned functional module 30 may be any one or at least two of the following: a light source module, an aromatherapy module, a negative ion generating module, an air purification module, and a control module, so as to provide corresponding lighting, aromatherapy, negative ion generation, air purification, control and other functions.

[0045] In this way, the speaker device 1 of this application embodiment, through the above-described structural configuration, when the speaker device 1, in addition to having a conventional speaker module 20, also has other functional modules 30 such as lights and aromatherapy, can be installed in the first opening 111 of the first housing 11, with the first opening 111 sealed and the sound output direction of the speaker module 20 facing outward of the first housing 11. Thus, when the functional module 30 is installed in the second opening 112 of the first housing 11 and the second opening 112 is sealed, the rear sound cavity 23 of the speaker module 20 can be formed by the first housing 11 and the functional module 30. That is, the sealing effect of the rear sound cavity 23 of the speaker module 20 of this speaker device 1 can be ensured simply by the sealed cooperation between the first housing 11 and the functional module 30. Thus, this speaker device 1 can effectively combine the speaker module 20 and the functional module 30, thereby saving the structural components of the rear sound cavity 23 of the sealed speaker module 20, making the structure of the entire speaker device 1 simpler and more compact.

[0046] In some examples, such as Figure 3 , Figure 4 and Figure 5 As shown, the functional module 30 includes a circuit board 31 and a functional device 32, with the functional device 32 disposed on the circuit board 31. The circuit board 31 has conductive lines, and the functional device 32 is electrically connected to the conductive lines. The circuit board 31 and / or the functional device 32 seal the second opening. Thus, with the above structural arrangement, the functional module 30 can effectively utilize its own structural components (i.e., the circuit board 31 and / or the functional device 32) to complete the sealing operation of the second opening 112.

[0047] It should be noted that, in this example, the functional module 30, in addition to including a circuit board 31 and a functional device 32 to complete the sealing operation of the second opening 112 using the circuit board 31 and / or the functional device 32, may also, according to actual sealing needs, further provide a sealing component (not shown) on the circuit board 31 or the functional device 32, so that the sealing operation of the second opening 112 can be achieved by the sealing component alone, or by the sealing component cooperating with at least one of the circuit board 31 and the functional device 32 to achieve the sealing operation of the second opening 112. Preferably, the sealing component may specifically be a sealing gasket, a sealing O-ring, or a sealing adhesive, etc.

[0048] In some examples, such as Figure 3 , Figure 4 and Figure 5As shown, the functional module 30 can specifically be a light source module, and the functional device 32 can specifically be a light source device. In this case, the first housing 11 is a lampshade that is at least partially transparent, and at least part of the light source device is located inside the lampshade. Thus, through the above structural arrangement, on the one hand, the light display effect of the light source device of this speaker device 1 can be ensured by the structure of installing the light source module in the second opening 112 of the lampshade and the structure of placing at least part of the light source device inside the lampshade. On the other hand, the structure of installing the speaker module 20 in the first opening 111 of the lampshade, sealing the first opening 111, and oriented the sound output direction of the speaker module 20 towards the outside of the lampshade, can ensure the sealing effect of the rear sound cavity 23 of the speaker module 20 when the light source module is installed in the second opening 112 of the lampshade and the second opening 112 is sealed. This means that the sealing effect of the rear sound cavity 23 of the speaker module 20 of this speaker device 1 can be ensured simply by the sealing fit between the lampshade and the light source module.

[0049] It should be noted that the lampshade in this example can be any shape capable of covering at least the light-emitting side of the light source module 30, including but not limited to frustum-shaped, spherical, pyramidal, and prism-shaped lampshades. Figure 4 and Figure 5 The lampshade shown is cylindrical. In this example, "at least some of the light source devices are located inside the lampshade" specifically means that when the light source module is installed in the second opening 112, at least part of the side containing the light source devices of the light source module is located inside the lampshade, while the other side of the light source module away from the light source devices is located outside the lampshade. This ensures that at least part of the light emitted by the light source devices passes through the lampshade to ensure the lighting display effect of the light source devices. Preferably, all the light emitted by the light source devices should illuminate the inside of the lampshade, meaning that all light source devices are located inside the lampshade. Furthermore, in this example, the wall thickness of the lampshade is preferably 1.5mm to 2.5mm, and the inner diameter of the lampshade cavity is preferably 60mm to 70mm. This ensures that the rear acoustic cavity 23 has a relatively large volume, and that the lampshade has good mechanical strength, while further ensuring the lighting display effect of the lampshade on the light source module. For those skilled in the art, the first housing 11 in this example can also be a common housing structure, in which case at least some of the light source devices are located outside the first housing 11. At this time, the light source device located outside the first housing 11 can be covered and protected by the second housing 12 mentioned later, and the corresponding lighting display effect can be ensured.

[0050] In some examples, the light source device is disposed on one side surface of the circuit board 31, and the side surface of the circuit board 31 on which the light source device is disposed directly abuts against the edge of the second opening 112 to seal the second opening 112. In this way, with the above-described structural arrangement, the light emitted by the light source device can at least partially illuminate the inside of the lampshade, while the circuit board 31 of the light source module effectively seals the second opening 112.

[0051] It should be noted that the circuit board 31 in this example can be either a separate circuit board for the light source module, including only the light source drive circuit for driving the light source device to perform illumination, or it can be the control board of the entire speaker device 1, including not only the light source drive circuit for driving the light source device to perform illumination, but also the drive circuit for driving the speaker module 20 and some circuits such as power management circuits necessary for the normal operation of the speaker device 1. In this case, in addition to being electrically connected to the light source device, the circuit board 31 can also be electrically connected to the speaker module 20, power module 40, button assembly 50, display module 60, etc. The power module 40 mentioned here mainly includes a charging interface and a battery to provide the electrical energy required for the normal operation of the speaker device 1. The button assembly 50 is mainly located on the surface of the housing assembly 10 for controlling the light source module and speaker module 20, such as switching them on and off. The display module 60 can specifically be a digital tube display module for displaying information such as power level. In this example, the light source device can specifically be one or more LED beads or other light sources, and when there are multiple light sources, they are arranged regularly on the same side surface of the circuit board 31, including but not limited to matrix array arrangement, or... Figure 4 The arrangement shown includes ring arrays and other similar configurations. In specific applications, the light source can be a surface-mount light source (e.g., an LED chip) mounted on the circuit board 31, and up to 12 light sources can be provided. In some optional configurations, the light source can also be a COB (Chip On Board) packaged light source. In some optional configurations, a light guide can be covered on the light source. The light guide can be ring-shaped or circular and fixed to the circuit board 31. In some optional configurations, the outer periphery of the light guide matches the shape and size of the inner periphery of the second opening 112, and the outer periphery of the light guide can be sealed to the inner side of the second opening 112.

[0052] In some examples, such as Figure 3 and Figure 4As shown, the side surface of the circuit board 31 where the light source device is located is also provided with a first elastic pad 311 that is adapted to the edge of the second opening 112. The side surface of the circuit board 31 where the light source device is located abuts against the edge of the second opening 112 through the first elastic pad 311 to seal the second opening 112. In this way, by providing the first elastic pad 311, the connection between the side surface of the circuit board 31 where the light source device is located and the edge of the second opening 112 can be made tighter, thereby further ensuring the sealing performance of the circuit board 31 of the light source module to the second opening 112.

[0053] It should be noted that the first elastic pad 311 in this example can specifically be a pad structure with good elasticity and sealing properties, such as foam, so that when the side surface of the circuit board 31 on which the light source device is located abuts against the edge of the second opening 112, the connection between the two is completely sealed by compressing the first elastic pad 311. Furthermore, when the first elastic pad 311 is preferably foam, the thickness of the foam is preferably 1mm to 2mm, and it preferably has a compression amount of 0.2mm to 0.6mm to better ensure the sealing performance of the circuit board 31 of the light source module to the second opening 112.

[0054] For those skilled in the art, in addition to sealing the second opening 112 in the manner described in the above example, the circuit board 31 can also seal the second opening 112 in the following manner: the outer periphery of the circuit board 31 is sealed to the inner side of the second opening 112 to seal the second opening 112. Specifically, the outer periphery of the circuit board 31 being sealed to the inner side of the second opening 112 can be directly and tightly fitted to the inner side of the second opening 112 to ensure a sealed connection, or the outer periphery of the circuit board 31 can be tightly fitted to the inner side of the second opening 112 through a sealing structure such as a sealing ring to ensure a sealed connection.

[0055] In some examples, such as Figure 3 , Figure 4 and Figure 5 As shown, at least one assembly positioning structure is also provided between the first housing 11 and the functional module 30. Thus, by providing the assembly positioning structure, it is convenient to quickly align and position the first housing 11 and the functional module 30 during assembly. Further, the assembly positioning structure includes a positioning post 71 and a positioning hole 72 that fit together, one of which is located on the first housing 11, and the other is located on the functional module 30. Thus, the mutual fitting of the positioning post 71 and the positioning hole 72 enables rapid alignment and positioning between the first housing 11 and the functional module 30.

[0056] It should be noted that, in this example, the positioning holes 72 are preferably located on the circuit board 31 of the functional module 30, and the number is preferably three or four, to further ensure the positioning accuracy between the first housing 11 and the circuit board 31 of the functional module 30. Correspondingly, in this example, the positioning posts 71 are preferably located on the first housing 11, and the number is the same as the number of positioning holes 72. Furthermore, when each positioning post 71 and its corresponding positioning hole 72 are fitted together, an elastic pad such as foam is sandwiched between each positioning post 71 and its corresponding positioning hole 72 to ensure that the sealing performance of the rear acoustic cavity 23 is not affected by the opening of the positioning holes 72.

[0057] In some examples, such as Figure 3 and Figure 4 As shown, the speaker module 20 includes a speaker component 21 and a module bracket 22. The module bracket 22 is located at the first opening 111 and is recessed towards the inside of the first housing 11. The speaker component 21 is mounted on the module bracket 22 and completely covers the first opening 111. Thus, with this structural arrangement, while the speaker module 20 is mounted at the first opening 111, the entire speaker module 20 is surrounded by the first housing 11, making the overall structure of the speaker device 1 more compact.

[0058] It should be noted that the speaker component 21 in this example can be a conventional speaker structure, capable of playing sounds such as white noise, music, and broadcasts. The module bracket 22 in this example can be a hollow structure, so that when the speaker component 21 is mounted on the module bracket 22, it will neither obstruct the sound output side of the speaker component 21 nor completely obstruct the side of the speaker component 21 away from the sound output.

[0059] In some examples, such as Figure 3 and Figure 4 As shown, the periphery of the module bracket 22 is integrally connected to the edge of the first opening 111. Thus, through the above structural arrangement, the bracket and the first housing 11 can form an integral structure, so that when assembling the speaker module 20, only the speaker component 21 needs to be installed on the module bracket 22 to achieve the installation and fixation of the entire speaker module 20 in the first opening 111.

[0060] It should be noted that, in this example, the integral connection between the periphery of the module bracket 22 and the edge of the first opening 111 specifically means that while the first housing 11 is recessed inward along the edge of the first opening 111 to form some stepped structures, it continues to extend inward to form the module bracket 22 that supports and mounts the speaker component 21. For those skilled in the art, to reduce the molding difficulty of the first housing 11, the first housing 11 and the module bracket 22 can also be molded separately, and then the periphery of the module bracket 22 can be fastened to the edge of the first opening 111 to achieve a fastening connection between the two. This fastening connection includes, but is not limited to, welding, bonding, etc.

[0061] In some examples, the speaker component 21 can be securely connected to the module bracket 22 via a screw structure or a snap-fit ​​structure. This structural arrangement facilitates the quick installation and removal of the speaker component 21 from the module bracket 22.

[0062] It should be noted that the screw structure in this example can specifically be a threaded engagement between a screw and a screw hole. The snap-fit ​​structure in this example can specifically be the mutual engagement between two snap-fits, or the mutual engagement between a snap-fit ​​and a snap-fit ​​hole (or slot). Preferably, a connecting portion 211 can be provided on the periphery of one end of the speaker component 21 in this example, so that the speaker component 21 can be fastened to the module bracket 22 by providing a screw hole or a snap-fit ​​or snap-fit ​​on the connecting portion 211. Further, a metal sheet can be provided on the periphery of one end of the speaker component 21 to form the aforementioned connecting portion 211.

[0063] In some examples, such as Figure 3 and Figure 4 As shown, the housing assembly 10 also includes a second housing 12, which surrounds the outer periphery of the first housing 11 and has a third opening 121 with the same opening orientation as the first opening 111. The second housing 12 is fastened to the first housing 11, and the edge of the third opening 121 abuts against one side surface of the speaker module 20 to press and fix the speaker module 20 onto the first housing 11. Thus, through the above structural arrangement, a dual-housing structure of the speaker device 1 can be realized. By fastening the second housing 12 to the first housing 11 while simultaneously pressing the edge of the third opening 121 against one side surface of the speaker module 20 to press and fix the speaker module 20 onto the first housing 11, the assembly of the second housing 12 and the first housing 11 is completed simultaneously with the assembly of the speaker module 20 and the first housing 11, thereby effectively improving the overall assembly efficiency of the speaker device 1.

[0064] It should be noted that in this example, the second housing 12 is fastened to the first housing 11, and the edge of the third opening 121 abuts against one side surface of the speaker module 20 to press and fix the speaker module 20 onto the first housing 11. Specifically, the second housing 12 is fastened to the first housing 11, and the edge of the third opening 121 abuts against the side surface of the speaker component 21 away from the module bracket 22 to press and fix the speaker module 20 onto the module bracket 22 connected to the first housing 11, thereby achieving a fixed connection between the speaker module 20 and the first housing 11. In this example, the shape of the second housing 12 is adapted to the shape of the first housing 11 to ensure that it can completely surround the outer periphery of the first housing 11. When the first housing 11 is specifically a lampshade and the functional module 30 is a light source module, the second housing 12 in this example is also preferably a lampshade to achieve a dual-lampshade structure of the speaker device 1, thereby further improving the lighting display effect of the light source module of the speaker device 1. A sandwiched cavity can be formed between the second housing 12 and the first housing 11. At least some functional devices can be disposed within the sandwiched cavity. For example, some light sources 32 are located inside the first housing 11, and some light sources 32 are located within the sandwiched cavity. In some optional embodiments, the functional devices 32 include a first functional device (e.g., a light source) and a second functional device (e.g., a negative ion generator). The first and second functional devices can be disposed separately inside the first housing 11 and within the sandwiched cavity. When a negative ion generator, an air purifier, or an aromatherapy device is disposed within the sandwiched cavity, the second housing 12 can be provided with ventilation holes. In this example, the fastening connection between the second housing 12 and the first housing 11 can also be achieved through the screw structure or snap-fit ​​structure mentioned in the above example. Furthermore, to facilitate the fastening connection between the second housing 12 and the first housing 11, in addition to the first opening 111 of the first housing 11 extending inward along its edge to form a first annular stepped portion 1111, the third opening 121 of the second housing 12 also extends inward along its edge to form a second annular stepped portion 1211. Thus, the second housing 12 and the first housing 11 can be fastened together by a screw structure or a snap-fit ​​structure. Additionally, when the second housing 12 is also specifically a lampshade, the wall thickness of the lampshade is preferably 2mm to 3mm, and the maximum diameter of the inner cavity of the lampshade is preferably 100mm to 110mm. This ensures that the lampshade has good mechanical strength while further ensuring the lighting display effect of the light source module.

[0065] In some examples, such as Figure 3 and Figure 4As shown, a second elastic pad 212 adapted to the edge of the third opening 121 is also provided on one side surface of the speaker module 20. The edge of the third opening 121 abuts against one side surface of the speaker module 20 through the second elastic pad 212. In this way, by providing the second elastic pad 212, the connection between the edge of the third opening 121 and one side surface of the speaker module 20 can be made tighter.

[0066] It should be noted that the second elastic pad 212 in this example can specifically be a pad structure with good elasticity and sealing properties, such as foam, so that when the edge of the third opening 121 abuts against one side surface of the speaker module 20, the connection between the two is completely sealed by compressing the second elastic pad 212. In this example, the second elastic pad 212 can be specifically provided on the connecting part 211 mentioned in the above example. In addition, when the second elastic pad 212 is preferably foam, the thickness of the foam is preferably 0.8mm to 1.2mm, and it is preferably compressed by 0.25mm to 0.45mm, so as to make the connection between the edge of the third opening 121 and one side surface of the speaker module 20 tighter.

[0067] In some examples, such as Figure 3 and Figure 4 As shown, the housing assembly 10 also includes a first cover 13 having a sound outlet 1311, which covers and is mounted on the third opening 121. Thus, with the above structural arrangement, a front sound cavity 24 for the speaker 21 can be formed between the first cover 13, the edge of the third opening 121, and the surface of the speaker 21 away from the module support 22, ensuring a tight seal for the remaining portion of the front sound cavity 24 except for the sound outlet.

[0068] It should be noted that the first cover 13 in this example may also have functions such as dust prevention and protecting the speaker component 21 from impact damage. In addition, the distance between the top of the speaker component 21 and the first cover 13 in this example is preferably 8mm to 10mm to ensure the sound output effect of the front sound cavity 24.

[0069] In some examples, such as Figure 3 and Figure 4 As shown, the first cover 13 includes a sound-emitting part 131 and a button part 132. The sound-emitting part 131 has a sound outlet 1311, and the button part 132 is disposed around the sound-emitting part 131 or on one side of the sound-emitting part 131. Thus, with the above structural arrangement, the first cover 13 can be used for both sound emission and button control.

[0070] It should be noted that the button section 132 in this example may specifically include a button panel and multiple button bodies. The button panel may be provided with multiple button contacts that surround the sound output section 131. The multiple button bodies are configured one-to-one with the multiple button contacts, so that when any button body is pressed, the corresponding button contact can be triggered to realize the corresponding button control function. Generally speaking, the button assembly 50 mentioned in the above example is mainly used for the control of the function module 30, or for the on / off control of the entire speaker device 1. However, the button section 132 in this example is mainly used for the control of the speaker component 21.

[0071] In some examples, such as Figure 3 , Figure 4 and Figure 6 As shown, the housing assembly 10 also includes a second cover 14. The second housing 12 also has a fourth opening 122 with the same opening orientation as the second opening 112. The second cover 14 is installed over the fourth opening 122, and the functional module 30 is located inside the second cover 14. Thus, through the above-described structure of the second cover 14, the second opening 112 of the second housing 12 can be sealed, while the second cover 14 simultaneously covers the functional module 30 located outside the first housing 11, thereby providing a certain degree of sealing and protection for the functional module 30.

[0072] It should be noted that in this example, the second cover 14 is recessed on the side facing the fourth opening 122 to form a receiving groove, so that the second cover 14 covers and is installed on the fourth opening 122. A certain receiving space can be formed by the receiving groove to accommodate and install the light source module and power module 40 mentioned in the above illustration.

[0073] In some examples, such as Figure 3 and Figure 4 As shown, the functional module 30 is also fastened to the second cover 14 by a screw structure or a snap-fit ​​structure. Thus, with the above structural arrangement, when assembling this speaker device 1, the functional module 30 can be first installed inside the second cover 14, and then, by having the second cover 14 cover the fourth opening 122, the side surface of the circuit board 31 of the functional module 30 where the light source device is located abuts against the edge of the second opening 112 through the first elastic pad 311 to seal the second opening 112.

[0074] It should be noted that the light source module in this example is fastened to the inside of the second cover 14 by a screw structure or a snap-fit ​​structure. Specifically, this means that the circuit board 31 of the functional module 30 is installed on the inside of the second cover 14 by the screw structure or snap-fit ​​structure mentioned in the above example.

[0075] In some examples, such as Figure 3 , Figure 4 and Figure 5 As shown, the first opening 111 and the second opening 112 are arranged opposite to each other, and when the speaker device 1 is placed on the supporting plane, the speaker module 20 is located on the side of the functional module 30 away from the supporting plane. In this way, with the above structural arrangement, the speaker module 20 is close to the top of the speaker device 1, and the functional module 30 is relatively close to the bottom of the speaker device 1. The rear sound cavity 23 is formed between the speaker module 20 and the functional module 30. This allows the speaker module 20 to be located above the functional module 30 when the speaker device 1 is placed on the supporting plane. This ensures that the supporting plane does not obstruct the sound outlet 1311 of the speaker module 20, while the lower part of the speaker module 20 is directly surrounded by the first housing 11 and the functional module 30 to form a rear sound cavity 23 with a large volume, thereby effectively improving the low-frequency sound effect of the speaker module 20.

[0076] It should be noted that, in this example, the distance between the bottom of the speaker component 21 and the circuit board 31 of the functional module 30 is preferably 80mm to 100mm, so as to take into account the miniaturization design requirements of this speaker device 1, while forming a rear sound cavity 23 with a large volume under the speaker module 20 through the first housing 11 and the functional module 30, so as to effectively improve the low frequency sound effect of the speaker module 20.

[0077] The technical means disclosed in this application are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.
