[0031] This disclosure provides a speaker assembly, including: a protective grille; a main unit, the circumferential surface of which is surrounded by the protective grille; and a battery. According to this disclosure, the main unit includes a base with a battery compartment and a cover covering the battery compartment, wherein the battery compartment is formed on the circumferential surface of the base and is capable of accommodating the battery, and wherein a heat dissipation pad is disposed on the side of the cover facing the battery compartment, the heat dissipation pad contacting the battery housed in the battery compartment, thereby conducting heat from the battery to the cover.

[0032] In existing technologies, the battery compartment for housing the battery has its opening located on the end side of the main unit. In this case, to replace the battery, the entire battery compartment must be pulled out from the end side of the main unit before the battery can be replaced. The drawbacks of this design are the complex battery replacement process and the lack of a heat exchange path between the battery and the external environment, leading to a risk of battery overheating. Unlike existing technologies, the battery compartment according to this disclosure is located in the circumferential surface of the main unit base. This fully utilizes the limited structural space of the speaker assembly, providing the battery compartment with the largest possible opening area, facilitating the removal of the old battery and the insertion of the new battery, and reducing the difficulty of battery replacement. Furthermore, the larger opening area of ​​the battery compartment provides an ample heat flow path between the battery and the external environment. In this case, a heat dissipation pad is provided on the side of the cover device facing the battery compartment. This heat dissipation pad is in close contact with both the battery and the cover device, further improving heat dissipation efficiency. The cover device achieves the dual functions of blocking the battery and dissipating heat to the outside environment in a compact structure.

[0033] According to one or more embodiments of this disclosure, the heat dissipation pad is made of silicone. Silicone has good thermal conductivity and also elastic deformation properties, thereby enabling it to adhere tightly to the battery and cover device under pressure, increasing the thermal conductivity area. This ensures good heat dissipation performance.

[0034] According to one or more embodiments of this disclosure, the heat dissipation pad has a thickness of 0.8 mm to 1.5 mm. Preferably, the heat dissipation pad has a thickness of 1 mm.

[0035] According to one or more embodiments of the present disclosure, the cover device includes a back plate and a battery compartment cover, wherein the back plate and the battery compartment cover are fixedly connected.

[0036] According to one or more embodiments of this disclosure, the back panel and the battery compartment cover are made of different materials and are interconnected by overmolding. Preferably, the back panel is made of plastic. Preferably, the battery compartment cover is made of metal. Particularly preferably, the battery compartment cover is made of aluminum alloy.

[0037] According to one or more alternative embodiments of this disclosure, the cover device is integrally constructed from the same material.

[0038] According to one or more embodiments of this disclosure, the cover device is detachably connected to the base. Preferably, the cover device is threadedly connected to the base. Particularly preferably, the battery compartment cover is threadedly connected to the edge of the battery compartment by means of at least two bolts. Threaded connections offer extremely high stability, minimizing undesirable deformation between the base and the cover device, thereby ensuring sealing and waterproofing.

[0039] According to one or more embodiments of this disclosure, a sealing ring is arranged between the battery compartment cover and the substrate.

[0040] According to one or more embodiments of this disclosure, the protective net device includes an opening for the back panel of the cover device, through which the back panel can be accessed from the outside. In this case, the back panel is exposed through the opening, while the battery compartment cover, which is fixedly connected thereto, is covered by the protective net device.

[0041] According to one or more embodiments of the present disclosure, the guard mesh device includes a dividing line extending at least partially along the axial direction of the speaker assembly, the guard mesh device being capable of opening and closing along the dividing line, thereby enabling a detachable connection between the guard mesh device and the base.

[0042] According to one or more embodiments of this disclosure, the protective net device includes a buckle facing the base, and the base includes a slot facing the protective net device, thereby enabling a detachable connection between the protective net device and the base.

[0043] According to one or more embodiments of this disclosure, the battery compartment is constructed as a die-cast part made of metal; preferably, the battery compartment is constructed as a die-cast part made of aluminum alloy. This allows for efficient heat dissipation from the speaker assembly during operation.

[0044] Figure 1 A perspective view of a speaker assembly 100 of this disclosure is schematically shown, which is exemplary configured as a portable speaker assembly and therefore has a relatively small volume. The speaker assembly 100 includes a protective grille 10, a main unit 20, and a battery 30, wherein the battery 30 is disposed inside the main unit 20 and is therefore not visible from the outside.

[0045] The main unit 20 is generally cylindrical in shape, including along such a... Figure 2 The substrate 22, extending longitudinally along the x-axis, has a battery compartment 22a with a rectangular cross-section formed on its circumferential surface. The battery 30 is detachably housed in the battery compartment 22a. The battery compartment 22a can be manufactured from metal, preferably aluminum alloy, using a die-casting process. The substrate 22 also includes an electroacoustic component and a charging component that works in conjunction with the battery. The electroacoustic component and the charging component operate in a known manner and therefore are not specifically labeled or described here.

[0046] The host unit 20 also includes a cover device 24, which is detachably connected to the base 22, thereby enabling the battery compartment 22a to be covered or opened.

[0047] The protective netting device 10 is made of a mesh material with numerous closely arranged perforations, thus providing excellent air permeability. The protective netting device 10 itself is constructed as a single unit, such as... Figure 1 As shown, the protective net device 10 has an opening 12 for the cover device 24, wherein the position and size of the opening 12 correspond to the back plate 242 of the cover device 24, thereby allowing access to the back plate 242 from the outside, but the battery compartment cover 244 is at least partially obscured. To facilitate user carrying and access to the speaker assembly 100, the speaker assembly 100 also includes a lanyard device 28. The lanyard device 28, as a detachable accessory, can be attached to the back plate 242 of the cover device 24.

[0048] Especially Figure 3 and Figure 4 As shown, the cover assembly 24 includes a longitudinally extending back plate 242 and a battery compartment cover 244 that is shorter and wider than the back plate 242. In this embodiment, the back plate 242 can be made of plastic, while the battery compartment cover 244 can be made of aluminum alloy, thus providing good electrical conductivity. The back plate 242 and the battery compartment cover 244 can be integrally constructed using an overmolding process. The overmolding process ensures a durable and reliable connection between the back plate 242 and the battery compartment cover 244, preventing possible displacement or deviation between them during operation. The width and length of the battery compartment cover 244 are sufficient to cover the battery compartment 22a. To achieve the connection between the cover assembly 24 and the base 22, a total of five through holes are provided on the edge of the battery compartment cover 244, and correspondingly, five screw holes are provided on the edge of the battery compartment 22a. The battery compartment cover 244 is threaded onto the battery compartment 22a using bolts 50, thereby achieving a detachable connection between the base 22 and the cover assembly 24.

[0049] To meet waterproofing requirements, a sealing device is provided between the substrate 22 and the cover device 24. Specifically, a sealing ring 246 is provided between the edge of the battery compartment 22a and the edge of the battery compartment cover 244 to prevent moisture and foreign objects from entering the battery compartment 22a.

[0050] During equipment operation, electronic components generate heat, which needs to be released to the external environment promptly and effectively. Therefore, a heat dissipation pad 40 is provided on one side of the battery compartment 22a of the cover device 24. Figure 2As shown, the heat dissipation pad 40 is positioned between the battery compartment cover 244 and the battery 30. The heat dissipation pad 40 is made of thermally conductive silicone and has a thickness of approximately 1 mm. Therefore, when the battery compartment cover 244 is installed on the battery compartment 22a, the cover slightly abuts against the battery 30 housed within the compartment. The resulting pressure causes the silicone heat dissipation pad 40 to deform slightly, ensuring it adheres tightly to the bottom side of the cover and maintains close contact with the battery 30. This increases the contact area and facilitates efficient heat transfer from the battery 30 to the battery compartment cover 244 via the heat dissipation pad 40. The aluminum alloy battery compartment cover 244 also possesses excellent thermal conductivity, further enhancing heat transfer efficiency.

[0051] Especially Figure 1 and Figure 2 As shown, the protective net device 10 has a dividing line 14 extending at least partially along the axial direction x. The protective net device 10 can be opened or closed along the dividing line 14. When the protective net device 10 is open, the base 22 of the main unit 20 is exposed. When the protective net device 10 is closed, it forms a cylindrical body adapted to the shape of the main unit 20 and surrounds the circumferential surface of the main unit 20. To strengthen the connection between the protective net device 10 and the main unit 20, a buckle 16 is provided on the side of the protective net device 10 facing the main unit 20, and a corresponding slot 26 is provided at the base 22 of the main unit 20. The buckle 16 and the slot 26 achieve a reliable connection between the protective net device 10 and the base 22, preventing accidental separation of the protective net device 10 and the base 22.

[0052] As previously mentioned, heat can be conducted from the battery 30 to the battery compartment cover 244 via the heat dissipation pad 40. Due to the porous design of the protective net device 10, heat can be released into the external environment through the protective net device 10 with extremely high efficiency.

[0053] When battery 30 needs to be replaced, first apply force to both sides of the protective net device 10 along the dividing line 14. This force overcomes the engaging force between the clip 16 and the slot 26, causing them to disengage and thus separating the protective net device 10 from the main unit 20. This exposes the battery compartment cover 244, which was previously covered by the protective net device 10. Use a screwdriver to remove the bolts 50, thereby removing the battery compartment cover 244 from the battery compartment 22a to remove the old battery from the battery compartment and insert the new battery.

[0054] The cover device 24 of the back panel 242 and the battery compartment cover 244 is integrated with the heat dissipation pad 40 mounted on the cover device 24. It not only acts as a stop for the battery, but also together serves as a good conductor to realize the heat dissipation path from the battery to the external environment. It achieves the dual functions of replaceable battery and battery heat dissipation in a compact structure.
