Description

Technical Field

[0001] This utility model relates to the field of audio equipment, and more particularly to a public square speaker that is easy to dissipate heat. Background Technology

[0002] The heat dissipation performance of outdoor audio equipment directly affects its stability and lifespan. Traditional audio equipment often uses active cooling solutions (such as built-in fans), but these solutions suffer from problems such as noise interference, motor damage, and dust accumulation leading to reduced heat dissipation efficiency. Especially in open environments such as squares, the equipment needs to work continuously for a long time. The continuous operation of the fan not only increases energy consumption but also easily attracts dust to form a thermal resistance layer, which in turn reduces heat conduction efficiency. In addition, fixed heat dissipation structures are difficult to adapt to different environmental temperature and humidity conditions. For example, passive heat dissipation is insufficient in hot weather, while ineffective fan operation in low-temperature environments results in energy waste.

[0003] Therefore, in order to address the above problems, a plaza sound system that facilitates heat dissipation is now being developed. Utility Model Content

[0004] To overcome the problems of traditional speakers that mostly use active cooling solutions, such as noise interference, easy motor damage, and dust accumulation leading to reduced cooling efficiency, especially in open environments such as squares where the equipment needs to work continuously for a long time, the continuous operation of the fan not only increases energy consumption but also easily attracts dust to form a thermal resistance layer, which reduces heat conduction efficiency. In addition, fixed cooling structures are difficult to adapt to different environmental temperature and humidity conditions. This utility model provides a square speaker that is easy to dissipate heat.

[0005] The technical solution of this utility model is: a plaza speaker that facilitates heat dissipation, comprising a plaza speaker, a control module on the top of the plaza speaker for overall control of the plaza speaker, a handle on the top of the plaza speaker, a back panel on the rear side of the plaza speaker, heat dissipation holes at the bottom of the back panel, a flap rotatably connected to the back panel for blocking the heat dissipation holes, and auxiliary heat dissipation components on both the left and right sides of the plaza speaker.

[0006] Furthermore, the auxiliary heat dissipation component includes air guides, which are provided on both the left and right sides of the plaza speaker. Each air guide has a trapezoidal flow channel inside and a first dustproof plate on it. Each air guide is connected to a limiting plate on its outer side, and a protective plate is slidably connected to each limiting plate. The protective plates are made of absorbent steel and are used to block the air guides. Two third magnetic blocks are provided on both the left and right sides of the plaza speaker, and the third magnetic blocks are used to attract and fix the adjacent protective plates.

[0007] Furthermore, it also includes a dustproof component, which includes a second dustproof plate. The second dustproof plate is provided on the front side of the plaza speaker. A fourth magnetic block is provided on the second dustproof plate and at the corresponding position of the plaza speaker. The upper and lower front sides of the second dustproof plate are provided with protruding plates, which allow users to quickly remove the second dustproof plate.

[0008] Furthermore, the handle has a groove that fits snugly against the user's fingers.

[0009] Furthermore, a first magnetic block is provided on the upper rear side of both the flip plate and the back plate, and two second magnetic blocks are provided on the lower part of both the flip plate and the lower rear side of the back plate.

[0010] Furthermore, all of the protective plates are L-shaped structures.

[0011] By adopting the above technical solution, compared with the prior art, this utility model has the following advantages:

[0012] This invention achieves a dynamic balance between fanless passive heat dissipation and dust prevention through the coordinated design of a magnetic flap and a flow guide channel. The honeycomb-shaped heat dissipation holes on the back panel and the trapezoidal flow guide channel form a natural convection channel, which accelerates the exhaust of hot air by utilizing the Bernoulli effect. The heat dissipation efficiency is significantly improved compared to traditional structures. Under normal temperature conditions, the flap closes to form a sealed space, reducing the risk of foreign object intrusion. The combination of the L-shaped protective plate and the third magnetic block enables the controllable opening and closing of the flow guide channel, taking into account both daily dust prevention and high-temperature heat dissipation needs.

Detailed Implementation

[0019] The present invention will now be described in detail with reference to the accompanying drawings.

[0020] A type of plaza speaker that facilitates heat dissipation, such as... Figures 1-5 As shown, the system includes a plaza speaker 1. A control module 2 is installed on the top of the plaza speaker 1. The control module 2 is used to control the plaza speaker 1 as a whole. A handle 3 is installed on the top of the plaza speaker 1. The handle 3 has a groove that can fit the user's fingers. A back panel 4 is installed on the rear side of the plaza speaker 1. A heat dissipation hole 5 is opened at the bottom of the back panel 4. A flip plate 6 is rotatably connected to the back panel 4. The flip plate 6 is used to block the heat dissipation hole 5. A first magnetic block 7 is installed on the upper rear side of both the flip plate 6 and the back panel 4. Two second magnetic blocks 8 are installed at the lower part of both the flip plate 6 and the lower rear side of the back panel 4. Auxiliary heat dissipation components 9 are installed on both the left and right sides of the plaza speaker 1.

[0021] The auxiliary heat dissipation component 9 includes an air guide 91. Air guides 91 are provided on both the left and right sides of the plaza speaker 1. The air guide 91 has a trapezoidal flow channel inside. A first dustproof plate 92 is provided on each air guide 91. A limiting plate 94 is connected to the outside of each air guide 91. A protective plate 93 is slidably connected to each limiting plate 94. The protective plates 93 are all made of adsorbable steel plate and have an L-shaped structure. The protective plates 93 are used to block the air guide 91. Two third magnetic blocks 95 are provided on both the left and right sides of the plaza speaker 1. The third magnetic blocks 95 are used to adsorb and fix the adjacent protective plates 93.

[0022] It also includes a dustproof component 10, which includes a second dustproof plate 101. The second dustproof plate 101 is provided on the front side of the square speaker 1. A fourth magnetic block 102 is provided on the second dustproof plate 101 and at the corresponding position of the square speaker 1. A protruding plate 103 is provided on the front side of both the upper and lower parts of the second dustproof plate 101. The protruding plate 103 can facilitate the user to quickly remove the second dustproof plate 101.

[0023] It should be noted that the working principle of this plaza speaker 1 is based on a synergistic heat dissipation mechanism of magnetic structure linkage and natural airflow. The airflow channel is adjusted by the opening and closing of the back panel 4 flip plate 6 to achieve passive heat dissipation without a fan. The control module 2 has a built-in temperature sensor (threshold set at 50℃). When the internal temperature of the device is detected to be ≤50℃, the back panel 4 flip plate 6 closes tightly under the action of the first magnetic block 7 (neodymium iron boron strong magnet, single set adsorption force 15N), and the heat dissipation hole 5 is blocked to form a sealed space. At this time, the air guide 91 of the auxiliary heat dissipation component 9 covers most of the air guide openings through the L-shaped protective plate 93 (normally fixed by the third magnetic block 95), allowing only a small amount of air to enter the speaker through the tiny gaps of the second dustproof plate 101 (stainless steel wire mesh, porosity 80%) of the dustproof component 10. Natural convection is formed. When the temperature is >50℃, the flap 6 is opened and the protective plate 93 on the outside of the air guide 91 is fixed to the third magnetic block 95 by the upward sliding limit plate 94. After the protective plate 93 is removed, the trapezoidal guide groove inside the air guide 91 is exposed. External air enters the bottom of the speaker tangentially along the guide groove. The Bernoulli effect is used to accelerate the internal hot air to be discharged from the honeycomb heat dissipation holes 5 (hole diameter 3mm, spacing 5mm) on the back plate 4, forming an airflow channel of "intake-exhaust". At the same time, the air guides 91 on both sides enhance the air exchange efficiency by increasing the opening area. The second dustproof plate 101 of the dustproof component 10 is automatically adsorbed more tightly in the high temperature mode due to the negative pressure of the airflow, preventing foreign objects from entering. The whole system achieves pure air dynamic heat dissipation circulation through dynamic adjustment of magnetic structure, geometric optimization of guide groove and balance of dustproof and breathable.

[0024] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by means of equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
