Description

Technical Field

[0001] The utility model relates to the technical field of speaker equipment, and specifically relates to an active line array speaker with a rainproof function. Background Art

[0002] A speaker is a device that converts audio signals into sound. It is the terminal of the entire audio system. Its function is to convert audio electrical energy into corresponding sound energy and radiate it into space. It is often used in indoor places such as homes, dance halls, KTVs, and movie theaters.

[0003] Nowadays, people's use of speakers is not limited to indoor areas. More often, they are used outdoors or in large squares. Since the outdoor venue is open and boundless in all directions, the sound of regularly arranged speakers cannot cover the entire venue. Therefore, a group of speakers are arranged vertically to form a line array speaker. In this way, each speaker has a conical radiation space, and the sound pressure of these conical spaces is correspondingly squeezed to form a horizontal elliptical overlapping space, which can cover a wider area. Since line array speakers are often used outdoors, they will inevitably encounter rainy weather. However, the existing active line array speakers do not have a rainproof function, which causes the power cord and signal line interfaces of the line array speakers to be easily wetted, and then leads to a short-circuit problem, easily causing equipment damage and huge losses to users. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the above defects of the prior art and provide an active line array speaker with a rainproof function when used outdoors.

[0005] The technical solution of the utility model is to provide an active line array speaker with a rainproof function having the following structure: including a speaker body, a power module and a pre-stage module arranged on the rear end face of the speaker body; two rainproof covers are connected to the rear end face of the speaker body, and the two rainproof covers are respectively used to cover the power module and the pre-stage module; an opening is provided at the lower end of the rainproof cover for the connectors of the power cord and the signal line to enter the rainproof cover and be connected to the corresponding power module and pre-stage module.

[0006] After adopting the above structure, the active line array speaker with a rainproof function in the utility model has the following advantages compared with the prior art:

[0007] By arranging rainproof covers at the positions of the power module and the pre-stage module on the rear end face of the speaker body and making the opening of the rainproof cover face downward, it is possible to prevent rainwater from falling into the interfaces of the power cord and the signal line inside the rainproof cover on rainy days, thereby realizing the rainproof function and avoiding short circuits caused by water leakage.

[0008] Preferably, the rain shield includes a front panel and two side panels respectively connected to both ends of the front panel. The side panels are arranged in a triangular shape with a gradually increasing width from top to bottom. One end of the side panel away from the front panel and the top end of the front panel are both connected to the rear end face of the speaker body, and an opening is formed at the lower end of the rain shield. This allows the opening at the lower end of the rain shield to be made larger, facilitating the insertion of the connectors of the power cord and the signal line.

[0009] Preferably, the front panel is made of a transparent material. Making the front panel transparent enables the user to see the plug-in panel inside the rain shield, facilitating the observation of the insertion situation of the power cord and the signal line.

[0010] Preferably, the side panels are made of a foldable flexible material, and the upper end of the front panel is rotatably connected to the rear end face of the speaker body. When the side panels are folded, the front panel is flush with the rear end face of the speaker body. With this arrangement, the rain shield can be folded up when the active line array speaker is not in use, making it flush with the rear end face of the speaker body. This not only facilitates storage but also prevents the rain shield from being damaged due to protrusion.

[0011] Preferably, two accommodation grooves corresponding to the rain shield are provided on the rear end face of the speaker body, and the power module and the pre-stage module are respectively located in the corresponding accommodation grooves. There is a space in front of the power module and the pre-stage module in the accommodation groove for accommodating the corresponding power cord connector and signal line connector. This allows the user to have sufficient space to insert the power cord connector and the signal line connector, making the insertion more convenient.

[0012] Preferably, a radiator is provided at the position between the two rain shields on the rear end face of the speaker body for dissipating heat from the power amplifier module. The power amplifier module generates a large amount of heat during operation. Connecting a radiator to the outer end of the power amplifier module can improve the heat dissipation efficiency, thereby enhancing the performance and service life of the device.

[0013] Preferably, the radiator includes a substrate and a heat dissipation tooth group. A rear hanging member is connected to the middle of the substrate. There are two heat dissipation tooth groups, which are symmetrically arranged on the substrate on both sides of the rear hanging member. Each heat dissipation tooth group includes a number of heat dissipation teeth, and the multiple heat dissipation teeth are arranged at intervals along the height direction of the substrate.

In this way, users have enough space to plug in the power cord connector and the signal line connector, making the plugging more convenient.

[0030] A radiator 5 is provided at the position between the two rain shields 4 on the rear end face of the sound box body 1 for dissipating heat from the power amplifier module. The power amplifier module generates a large amount of heat during operation. Connecting a radiator 5 to the outer end of the power amplifier module can improve the heat dissipation efficiency, thereby improving the performance and service life of the device.

[0031] The radiator 5 includes a base plate 51 and heat dissipation tooth groups 52. A rear hanging member 6 is connected to the middle of the base plate 51. There are two heat dissipation tooth groups 52, which are symmetrically arranged on the base plate 51 on both sides of the rear hanging member 6.
