Description
Technical Field
[0001] This utility model relates to the field of power amplifier technology, and in particular to a home-use combined power amplifier. Background Technology
[0002] With the increasing demand for home audio-visual entertainment, home combination amplifiers, as core devices that integrate functions such as audio signal amplification and speaker connection, are being used in an increasingly wide range of scenarios.
[0003] In home audio-visual systems, amplifiers and speakers are core components that often need to be placed together to ensure optimal audio transmission. However, home amplifiers and speakers are typically placed independently, requiring additional storage space on shelves, desktops, or the floor. This not only limits their placement within the home environment but can also lead to a large overall footprint and visual clutter, failing to meet users' needs for tidiness and efficient space utilization. Furthermore, connecting amplifiers and speakers requires various audio and power cables, and current placement methods lack dedicated cable management structures, leaving cables exposed. This not only affects the aesthetics of the home but also poses risks of tangling and wear, potentially leading to unstable signal transmission and consequently impacting audio playback quality. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing home amplifiers and speakers, which are mostly placed independently and require additional storage space on ordinary shelves, desktops, or floors. This not only makes them susceptible to limitations in home layout but also results in a large overall space occupation and visual clutter due to the scattered placement of the equipment, failing to meet users' needs for home tidiness and space utilization. At the same time, the connection between the amplifier and the speaker requires various audio cables and power cables, and the existing placement method lacks a dedicated cable management structure, making the cables easily exposed. This not only affects the aesthetics of the home but also poses risks of cable tangling and wear, which may lead to unstable signal transmission and thus affect audio playback quality. Therefore, this utility model proposes a home-use combined amplifier.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A home-use modular amplifier includes a central base, with side bases connected to both sides of the central base via a quick-locking structure. A heat sink is placed on the central base, and an amplifier is mounted on top of the heat sink. Speakers are placed on the side bases. A heat sink with ventilation holes is fixedly connected inside both the central base and the side bases. A cable management component is provided at the bottom of the central base for easy cable management. Casters are fixedly installed at the bottom of both the central base and the side bases.
[0007] Preferably, the quick-locking structure includes openings on both sides of the outer wall of the central base, a spring fixedly connected to the inner wall of the opening, a limit rod slidably connected inside the opening, and a limit groove formed on the outer wall of the side base.
[0008] Preferably, the shape of the limiting rod is adapted to the limiting groove.
[0009] Preferably, one end of the spring is fixedly connected to the inner wall of the opening, and the other end of the spring is fixedly connected to the outer wall of the limiting rod.
[0010] Preferably, the limiting rod is L-shaped.
[0011] Preferably, the inner wall of the opening is provided with sliding grooves on the upper and lower sides, and the limiting rod is slidably connected to the sliding grooves.
[0012] Preferably, the storage component includes an L-shaped connecting plate fixedly connected to the bottom of the central base, and a storage box is slidably connected inside the connecting plate via a slide rail.
[0013] Preferably, the outer wall of the storage box has a through hole, and the outer wall of the storage box has a groove for pulling out a handle.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. When in use, this utility model can integrate the amplifier and speakers through the combination design of the central base and the side base, without the need for additional ordinary shelves, desktop or floor space, breaking the problem of the traditional independent placement mode being restricted by home layout; at the same time, it avoids the problem of large space occupation and visual clutter caused by scattered equipment, effectively improving the cleanliness and space utilization of the home, and meeting the user's needs for the aesthetics of the home environment.
[0016] 2. When in use, this utility model can use the storage component set at the bottom of the central base to specifically store various audio cables and power cables required for connecting the amplifier and speakers, avoiding the cables being exposed. This solves the risks of cable tangling and wear in traditional placement methods, prevents unstable signal transmission due to cable problems, and thus ensures audio playback quality. Moreover, users do not need to purchase additional storage accessories, improving ease of use. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0024] Reference Figures 1-5 A home-use modular amplifier mainly includes a center base 1, side bases 2, a heat sink 3, an amplifier 4, a speaker 5, a heat sink 6, a cable management assembly 7, and casters 8.
[0025] The central base 1 serves as the core load-bearing structure, with two side bases 2 connected to it via quick-locking mechanisms, forming a stable and expandable base platform. A heat sink 3 is placed on the central base 1 to provide heat dissipation for the amplifier 4, which is then fixedly mounted on top of the heat sink 3. The side bases 2 support the speakers 5. Both the central base 1 and the side bases 2 have embedded heat sinks 6 with densely packed ventilation holes to ensure effective heat dissipation during operation. A storage component 7 is located at the bottom of the central base 1 to organize and conceal connecting cables, preventing clutter. Casters 8 are installed at the four corners of both the central base 1 and the side bases 2, enabling the entire device to move freely.
[0026] The quick-locking structure is key to enabling the rapid connection and separation of the central base 1 and the side base 2. Its specific components are as follows:
[0027] On the opposite outer walls of the central base 1, there is a through-hole 9 on each side. Each through-hole 9 is a rectangular channel with two symmetrical sliding grooves 10 on its upper and lower inner walls. An L-shaped limiting rod 12 is slidably installed within the through-hole 9, with protrusions on its upper and lower sides that mate with the sliding grooves 10, allowing the limiting rod 12 to slide smoothly along the trajectory defined by the sliding grooves 10. A spring 11 is housed within the through-hole 9, with one end fixedly connected to the inner wall of the through-hole 9 (the end furthest from the opening), and the other end fixedly connected to the outer wall of the long arm of the L-shaped limiting rod 12. In its natural state, the elastic force of the spring 11 drives the limiting rod 12 to slide outwards from the through-hole 9, causing it to partially extend beyond the through-hole 9.
[0028] On the outer wall of the side base 2 where it meets the center base 1, a limiting groove 13 is provided that is perfectly matched to the shape of the extended part of the L-shaped limiting rod 12.
[0029] When the side base 2 needs to be installed onto the center base 1, the operator simply aligns the side base 2 with the side of the center base 1 and pushes it inward. The end of the side base 2 will first contact and press against the slightly protruding L-shaped limiting rod 12, forcing the limiting rod 12 to retract and slide into the opening 9 against the elastic force of the spring 11. When the side base 2 is fully in place and the limiting groove 13 on it has just moved to the position aligned with the limiting rod 12, the restoring force of the spring 11 will immediately push the limiting rod 12 into the limiting groove 13, making a "click" sound, thus completing the locking. At this time, the side base 2 and the center base 1 are firmly connected.
[0030] When separation is required, the operator pulls the limiting rod 12 outward (in the direction of spring 11 compression) to completely disengage it from the limiting groove 13 on the side base 2. Once the limiting rod 12 is disengaged, the side base 2 can be easily pulled off the central base 1, achieving rapid separation. This design requires no tools, enabling quick manual assembly and disassembly, greatly facilitating equipment layout adjustments and transportation.
[0031] The storage component 7 is located at the bottom of the central base 1 and is used to centrally manage the connecting cables between devices such as amplifiers and speakers, keeping the environment clean.
[0032] The component mainly includes an L-shaped connecting plate 14 and a storage box 15. One side of the L-shaped connecting plate 14 is fixedly mounted on the bottom surface of the central base 1, and the other side extends vertically downward to form a guide rail mounting surface. A slide rail (not shown in the figure) is installed on this vertical side. The storage box 15 is a box-shaped body that is open on the top and one side (the side facing the outside of the device), and it is slidably connected to the L-shaped connecting plate 14 through the slide rail, so that the storage box 15 can be pulled out or pushed back like a drawer.
[0033] Multiple through holes 16 are provided on the outer wall of the storage box 15. These through holes are used to introduce various cables from the outside into the storage box 15. Above the through holes 16, a recessed handle groove 17 is also provided. The handle groove 17 allows the user to easily pull the storage box 15 out from the bottom of the central base 1 by gripping it with their fingers and applying force.
[0034] When wiring, the user simply pulls out the storage box 15 by holding the handle slot 17, then passes all the necessary device cables through the through holes 16 into the storage box 15, and organizes and connects them inside. After completion, any excess cables are coiled inside the storage box 15, and then the storage box 15 is pushed back to the bottom of the central base 1. All messy cables are hidden within the storage space, resulting in a neat appearance and avoiding the tripping hazard of cables dragging on the ground, while also facilitating the overall movement of the equipment.
[0035] Working principle:
[0036] In use, the user first installs the two side bases 2 onto the center base 1 using the quick-locking mechanism, forming a complete base. Then, the heat sink 3 is placed on the center base 1, the amplifier 4 is mounted on the heat sink 3, and the speakers 5 are placed on the two side bases 2. Next, the cables between all devices are connected and stored using the bottom storage assembly 7. Finally, by pushing the device and using the bottom casters 8, the entire system can be easily moved to the desired location.
[0037] When transporting or entering confined spaces, simply unplug the cable (which is neatly arranged for easy plugging and unplugging), pull the limit lever 12, and remove the side base 2 and the speaker 5 on it. This allows the entire device to be disassembled into smaller modules, greatly improving portability and space adaptability. The built-in heat sink 6 effectively ensures stable operation of high-power devices such as amplifiers for extended periods.
[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
