[0070] Figure 1 A perspective view schematically showing the loudspeaker assembly 100 of the present disclosure. Figure 2 An exploded view schematically showing some components of the loudspeaker assembly 100 of the present disclosure.
[0071] The loudspeaker assembly 100 is configured as a portable loudspeaker assembly and thus has a relatively small size. The loudspeaker assembly 100 mainly includes a grille device 10, a main body 20, and a battery 30. The battery 30 is arranged inside the main body 20 and is thus not visible from the outside.
[0072] The main body 20 is generally cylindrically configured and extends longitudinally along the axial direction x as shown in Figure 1 The main body 20 includes a base unit 22 and a back plate unit 24. In the embodiment shown in Figures 1 to 7 the back plate unit 24 is detachably connected to the base unit 22, and the back plate unit 24 and the base unit 22 can be threadedly connected to each other by means of a plurality of bolts. However, in an embodiment not shown, the base unit 22 and the back plate unit 24 can also be integrally configured or inseparably fixedly connected to each other. The base unit 22 further includes an electroacoustic component and a charging component that cooperates with the battery. The electroacoustic component and the charging component operate in a known manner and are not specifically labeled or described herein.
[0073] The grille device 10 is made of a mesh material and has a large number of perforations arranged closely, so it has excellent air permeability and heat dissipation performance. The grille device 10 is integrally configured and has a dividing line 14 that at least partially extends along the axial direction x. The grille device 10 can be opened or closed along the dividing line 14. When the grille device 10 is opened, the base unit 22 of the main body 20 is exposed; when the grille device 10 is closed, it forms a cylindrical body that fits the shape of the main body 20 and surrounds the circumferential surface of the main body 20, and only the back plate unit 24 is exposed outward at the opening 12. To strengthen the connection between the grille device 10 and the main body 20, a snap is provided on the side of the grille device 10 facing the main body 20, and a slot is correspondingly provided at the base unit 22 of the main body 20. The reliable connection between the grille device 10 and the base unit 22 is achieved through the snap and the slot, preventing the grille device 10 from being accidentally separated from the base unit 22.
[0074] As shown in Figure 1 and 2 As shown, the protective net device 10 has an opening 12 for the back panel unit 24, so that the back panel unit 24 can be accessed from the outside.
[0075] The backplane unit 24 includes a backplane 240. In particular, as shown... Figure 3 As shown, the main body section of the backplate 240 extends longitudinally, and the backplate 240 is connected to the base 22 via a backplate mounting portion 240a. In this embodiment, the main body section of the backplate 240 is made of plastic, while the backplate mounting portion 240a can be made of aluminum alloy. The backplate 240 is integrally constructed; for example, the main body section of the backplate 240 and the backplate mounting portion 240a can be integrally constructed using an overmolding process. The overmolding process ensures a durable and reliable fixed connection between the main body section of the backplate 240 and the backplate mounting portion 240a, preventing possible displacement and deviation between them during operation. To achieve the connection between the back plate 240 and the base unit 22, multiple through holes are provided on the edge of the back plate mounting part 240a, and corresponding number of screw holes are provided on the base unit 22 in the same position. The back plate 240 is threaded onto the base unit 22 by means of bolts, thereby achieving a detachable connection between the base unit 22 and the back plate 240.
[0076] To improve the portability of the speaker assembly 100, the back panel unit 24 is also equipped with a suspension device 26. With the speaker assembly 100 assembled, at least a portion of the back panel unit 24 is exposed through the opening 12 of the grille 10. The suspension device 26 is externally connected to this portion of the back panel unit 24, allowing the user to hold the suspension device 26 to carry or retrieve the speaker assembly 100. If necessary, such as when the grille 10 needs to be removed from the main unit 20 for battery replacement, the connection between the suspension device 26 and the back panel unit 24 may obstruct operation. Therefore, the suspension device 26 should be detachable from the back panel unit without damage.
[0077] The suspension device 26 may include a suspension portion 260 and a snap-fit member 264 fixedly connected to the suspension portion 260 via a connector portion 262. The snap-fit member 264 is constructed in a ring shape using a rigid material, such as a metal ring. The suspension device 26 can be detachably connected to the backplate unit 24 using the snap-fit member 264.
[0078] The suspension part 260 can have a variety of different implementations.
[0079] For example in Figures 8a to 8b In the embodiment shown, the suspension part 260 is constructed as a flexible hanging rope, the two ends of which are connected at the joint part 262 to form a closed suspension ring.
[0080] exist Figures 9a to 9b In the illustrated embodiment, the suspension portion 260 is constructed as a hanging ring made of a rigid material, such as metal or rigid plastic. The hanging ring may include a first segment 2602 and a second segment 2604, which together form a complete suspension ring. For this purpose, the first segment 2602 may be C-shaped, and the second segment 2604 may be connected to two opposing free ends of the first segment 2602 via its two ends. Specifically, the first end 2604a of the second segment 2604 may be pivotally connected to one end of the first segment 2602, and the second end 2604b of the second segment 2604 may be engaged with the other opposing end of the first segment 2602. Alternatively, in an embodiment not shown, the second segment 2604 may also be threadedly connected to the corresponding end of the first segment 2602 via a threaded sleeve at its second end 2604b.
[0081] To enable a simple detachable connection between the suspension device 26 and the backplate unit 24, the backplate unit 24 further includes a mounting base 242, a latch 244, a rotating shaft 246, and a pressing element 248. The suspension device 26 can switch between a locked position and a released position, thereby allowing the suspension device 26 to be reliably connected to or easily separated from the backplate unit 24.
[0082] The back plate 240 includes an inclined section 2402 extending downward from the top surface, a snap-fit guide port 2404 for allowing the snap-fit 264 of the suspension device 26 to be inserted is provided at one of the transition points between the lowest point of the inclined section 2402 and the top surface, and a press-fit receiving portion 2406 for the press-fit 248 is also provided in the back plate 240.
[0083] Mounting base 242 includes a rotating shaft hole 2420 through which a rotating shaft 246 passes, a base bottom 2422, and a snap-fit groove 2424 adjacent to the base bottom 2422.
[0084] The hook 244 includes a pivot portion 2440 through which the rotating shaft 246 passes, a first hook arm 2442 and a second hook arm 2444 extending to both sides from the pivot portion 2440, wherein the second hook arm 2444 includes a hook-like element at its free end.
[0085] The pressing member 248 is constructed in the form of a button, and includes a generally planar extending top surface and a first protrusion 2482 and a second protrusion 2484 extending downward from its bottom surface.
[0086] In the assembled state, the mounting base 242 is fixedly connected to the back plate 240 from below by bolts 50, wherein the base bottom 2422 of the mounting base 242 can extend obliquely. The mounting base 242 is adjacent to the oblique section 2402 of the back plate 240, thus forming a substantially continuous channel bottom, wherein the oblique angle of the base bottom 2422 is generally consistent with the oblique section 2402 of the back plate 240. Thus, the connector 262 of the suspension device 26, together with the snap-fit member 264, can be smoothly guided along the oblique section 2402 of the back plate 240 and through the snap-fit member guide port 2404 into the base bottom 2422 of the mounting base 242, wherein the snap-fit groove 2424 is narrower than the snap-fit member guide port 2404, thereby allowing the snap-fit member 264 to pass through the snap-fit groove 2424.
[0087] The rotating shaft 246 passes through both the rotating shaft hole 2420 of the mounting base 242 and the pivot portion 2440 of the hook 244. The first hook arm 2442 points towards the pressing member 248, while the second hook arm 2444 points towards the suspension device 26. A preload is applied to the hook 244 by means of a biasing member 40, causing the hook 244 to tend to press down its second hook arm 2442, thereby engaging the hook with the inserted latching member 264. In this embodiment, the biasing member 40 is constructed as a return spring, with one end acting on the hook 244 and the other end acting on the mounting base 242.
[0088] The pressing member 248 is movably arranged in the pressing member receiving portion 2406. The first protrusion 2482 of the pressing member 248 points towards the first hook arm 2442 of the hook 244, so that pressure can be applied to the first hook arm 2442 by the descent of the pressing member 248, thereby causing the hook 244 to swing around the rotation axis 246 against the preload of the biasing member 40. To prevent the pressing member 248 from being pressed down excessively, the inner wall of the pressing member receiving portion 2406 includes a stop flange 2408 that can abut against the second protrusion 2484 of the pressing member 248, thereby limiting the descent of the pressing member 248.
[0089] When the suspension device 26 is in the locked position, such as Figure 4 and Figure 5 As shown, the snap-fit component 264, together with the connector portion 262, is inserted into the guide channel formed by the back plate 240 and the base bottom 2422 of the mounting base 242. The connector portion 262, due to its greater thickness, is stopped by the snap-fit groove 2424 of the mounting base 242, with only the snap-fit component 264 passing through the snap-fit groove 2424. Under the action of the biasing member 40, the first snap-fit arm 2442 of the snap-fit hook 244 tilts upward, and the second snap-fit arm 2444 depresses downward, maintaining engagement with the snap-fit component 264 of the suspension device 26 using its hook-shaped element 2424.
[0090] When it is desired to detach the suspension device 26 from the back panel unit 24, pressure is applied to the top surface of the pressing member 248 to lower it. During this process, the first protrusion 2482 of the pressing member 248 applies pressure to the first hook arm 2442 of the hook 244. This causes the hook 244 to overcome the restoring force of the bias member 40 and swing about the rotation axis 246 passing through its pivot portion 2440, causing the first hook arm 2442 to lower and the second hook arm 2444 to rise, thereby releasing the engagement between the second hook arm 2444 and the engaging member 264 of the suspension device 26, thus releasing the suspension device 26 to the released position. At this point, the user is allowed to pull the suspension device 26 outwards to detach it from the back panel unit 24, such as... Figure 6 and Figure 7 As shown.
[0091] When it is desired to connect the suspension device 26 to the backplate unit 24, the connector 262 of the suspension device 26, together with the snap-fit member 264, is inserted along the snap-fit guide port 2404 of the backplate 240. The snap-fit member 264 further passes through the snap-fit groove 2424 of the mounting base 242 and acts on the second snap-fit arm 2444 of the snap hook 244, causing the snap hook 244 to swing about the rotation axis 246 passing through its pivot portion 2440. During this process, the snap hook 244 first overcomes the restoring force of the biasing member 40, causing the second snap-fit arm 2444 to tilt upwards and the first snap-fit arm 2442 to press downwards. When the hook-shaped part of the second snap-fit arm 2444 engages with the snap-fit member 264, the second snap-fit arm 2444 is pressed downwards under the restoring force of the biasing member 40, thereby achieving… Figure 4 and Figure 5 The locking position is shown.
