Description
Technical Field
[0001] This utility model relates to the field of active speaker technology, and in particular to a heat dissipation structure for an active speaker amplifier. Background Technology
[0002] Active speakers, also known as powered speakers, have built-in amplifier circuits, so users don't need to worry about matching them with amplifiers. They are also easy to drive directly with lower-level audio signals. They usually refer to speakers with built-in power amplifiers, such as multimedia computer speakers, active subwoofers, and some newer home theater active speakers.
[0003] Existing active speakers suffer from uneven heat dissipation due to their internal cooling devices, which can easily lead to heat accumulation inside the speaker enclosure. Furthermore, the cooling devices are often integrated structures, making them impossible to disassemble and repair after damage, which greatly reduces reusability and increases operating costs. Therefore, we have introduced a new active speaker amplifier cooling structure. Utility Model Content

[0010] Preferably, the four air outlet pipes are located at the four corners inside the speaker body, and the plurality of air outlet holes are distributed at equal distances.
[0011] By adopting the above technical solution: since the four air outlets are located at the four corners inside the speaker body and the several air outlets are distributed at equal distances, the cool air can be evenly distributed inside the speaker body, thereby improving the heat dissipation effect of the speaker body.
[0012] Preferably, the moving mechanism includes a connecting seat, the upper end of which has a connecting groove, and the left and right walls of the connecting groove both have T-shaped slots. The four corners of the lower end of the connecting seat are fixedly installed with moving wheels. The middle of the left end and the middle of the right end of the connecting seat are fixedly connected with mounting strips. The upper ends of the two mounting strips are threadedly connected with limit screws, and the ends of the two limit screws are fixedly connected with anti-slip pads.
[0013] Preferably, the lower wall of the connecting groove contacts the bottom of the speaker body, and the two T-shaped slots are respectively embedded and connected to the two T-shaped clips.

[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] 1. By setting up a heat dissipation mechanism, the mounting plate is installed at the rear of the speaker body with four fixing screws, so that the four air outlet pipes are located at the four corners inside the speaker body. This allows the heat dissipation mechanism to be easily disassembled and assembled. When the air cooler is turned on, the air cooler sends cold air into the air collection box through the air inlet pipe, and then into the four air outlet pipes through the four branch pipes. Finally, the air is sent into the speaker body through the air outlet holes on the four air outlet pipes for heat dissipation. Since the four air outlet pipes are located at the four corners inside the speaker body and the air outlet holes are evenly distributed, the cold air can be evenly distributed inside the speaker body, thereby improving the heat dissipation effect of the speaker body.

When the speaker needs to be carried for a long distance, the lower part of the speaker can be placed in the connecting slot from the rear of the connector, so that the two T-shaped clips are respectively embedded in the two T-shaped slots, making it easy to install the connector on the lower part of the speaker. The moving wheels at the bottom of the connector facilitate the long-distance carrying of the speaker. After being carried to the place of use, the two limiting screws are rotated to make the two anti-slip pads fit tightly with the ground, thereby limiting and fixing the speaker at the place of use and maintaining the stability of the speaker during use.

[0028] Please see Figure 1-4 This utility model provides a technical solution:
[0029] An active speaker amplifier heat dissipation structure includes a speaker body 1, a heat dissipation mechanism 2 detachably connected to the rear end of the speaker body 1, heat dissipation grooves 3 provided at the middle of the left end and the middle of the right end of the speaker body 1, T-shaped clips 4 fixedly connected to the lower left end and the lower right end of the speaker body 1, a moving mechanism 5 connected to the lower part of the speaker body 1 by two T-shaped clips 4, and a handle 6 provided at the middle of the upper end of the speaker body 1, with an anti-slip sleeve 7 provided on the outer surface of the handle 6.
[0030] In this embodiment, the heat dissipation mechanism 2 includes a mounting plate 21. A cooler 22 is fixedly mounted on the middle of the rear end of the mounting plate 21. An air inlet pipe 23 is fixedly connected to the output end of the cooler 22. An air collection box 24 is fixedly connected to the front end of the air inlet pipe 23. Four diverter pipes 25 are fixedly connected to the outer surface of the air collection box 24. An air outlet pipe 26 is fixedly connected to the end of each of the four diverter pipes 25 away from the air collection box 24. Several air outlet holes 27 are opened on the outer surface of each of the four air outlet pipes 26. Fixing screws 28 are threaded through the four corners of the rear end of the mounting plate 21. The mounting plate 21 is threadedly connected to the rear end of the speaker body 1 through the four fixing screws 28. The rear end of the air collection box 24 is fixedly connected to the mounting plate 21. The air collection box 24 is connected to the interior of the four air outlet pipes 26 through the four diverter pipes 25. The four air outlet pipes 26 are located at the four corners inside the speaker body 1. Several air outlet holes 27 are distributed at equal distances.
[0031] The above solution involves installing the mounting plate 21 at the rear of the speaker body 1 using four fixing screws 28, positioning the four air outlet pipes 26 at the four corners inside the speaker body 1, and facilitating the easy disassembly and assembly of the heat dissipation mechanism 2. By activating the air cooler 22, the air cooler 22 sends cold air into the air collection box 24 through the air inlet pipe 23, and then into the four air outlet pipes 26 through the four branch pipes 25. Finally, the cold air is sent into the speaker body 1 through the air outlet holes 27 on the four air outlet pipes 26 for heat dissipation. Since the four air outlet pipes 26 are located at the four corners inside the speaker body 1, and the air outlet holes 27 are evenly distributed, the cold air can be evenly distributed inside the speaker body 1, thereby improving the heat dissipation effect of the speaker body 1.
[0032] In this embodiment, the moving mechanism 5 includes a connecting seat 51. A connecting groove 52 is provided at the upper end of the connecting seat 51. T-shaped slots 53 are provided on the left and right walls of the connecting groove 52. Moving wheels 54 are fixedly installed at the four corners of the lower end of the connecting seat 51. Mounting strips 55 are fixedly connected to the middle of the left and right ends of the connecting seat 51. Limiting screws 56 are threaded through the upper ends of the two mounting strips 55. Anti-slip pads 57 are fixedly connected to the ends of the two limiting screws 56. The lower wall of the connecting groove 52 contacts the bottom of the speaker body 1. The two T-shaped slots 53 are respectively embedded and connected to the two T-shaped clips 4. The two limiting screws 56 are symmetrically distributed from left to right. The two anti-slip pads 57 are respectively located below the two mounting strips 55.
[0033] With the above solution: when the speaker body 1 needs to be carried for a short distance, it can be carried directly by the handle 6. When the speaker body 1 needs to be carried for a long distance, the lower part of the speaker body 1 can be placed in the connecting groove 52 from the rear of the connecting seat 51, so that the two T-shaped clips 4 are respectively embedded in the two T-shaped clips 53, making it easy to install the connecting seat 51 on the lower part of the speaker body 1. The moving wheels 54 at the bottom of the connecting seat 51 facilitate the long-distance carrying of the speaker body 1. After being carried to the place of use, the two limiting screws 56 are rotated to make the two anti-slip pads 57 fit tightly with the ground, so that the speaker body 1 can be fixed at the place of use and maintain the stability of the speaker body 1 during use.
[0034] It should be noted that this utility model is a heat dissipation structure for an active speaker amplifier. During use, the mounting plate 21 is assembled to the rear of the speaker body 1 using four fixing screws 28, ensuring that the four exhaust pipes 26 are placed in the four corners inside the speaker body 1. This layout makes the heat dissipation mechanism 2 easy to install and remove. After the cooler 22 is turned on, cold air is sent into the air collection box 24 through the air inlet pipe 23, and then guided to the four exhaust pipes 26 by the four branch pipes 25 respectively. Finally, through the evenly distributed air outlets 27 on the exhaust pipes 26, the cold air is evenly distributed into the interior of the speaker body 1, effectively improving the heat dissipation performance. In addition, regarding the speaker body 1's... To meet different carrying needs, two convenient carrying methods are provided: for short-distance carrying, the speaker can be carried directly by holding the handle 6; for long-distance carrying, the lower part of the speaker body 1 is slid into the connecting groove 52 from the rear side of the connecting seat 51, ensuring that the two T-shaped clips 4 are accurately embedded in the corresponding T-shaped clips 53, so that the connecting seat 51 is installed under the speaker body 1. With the help of the moving wheels 54 at the bottom of the connecting seat 51, the long-distance movement of the speaker body 1 becomes easy and free. After reaching the destination, the two limiting screws 56 are rotated to make the anti-slip pad 57 make close contact with the ground, thereby achieving a stable limit on the speaker body 1 and ensuring its stability during use.
