Description

Technical Field

[0001] The utility model relates to the technical field of audio equipment, in particular to a novel shell structure of an audio equipment. Background Art

[0002] Audio refers specifically to an audio system that is a combination of electrical equipment that produces sound. The audio system generally includes: 1. Sound source equipment (for example: DVD, CD, MP3, MP4, computer, mobile phone, microphone and other sound source output devices), 2. Audio signal dynamic processing equipment (compressors, effects, mixers, audio processors, equalizers and other audio signal processing equipment), 3. Audio signal amplification equipment (pre-stage power amplifiers, post-stage power amplifiers, digital power amplifiers and other analog power amplifiers and equipment), 4. Sound restoration equipment (full-range speakers, ceiling speakers, sound columns, line array speakers, array speakers, tweeters, subwoofers, etc.).

[0003] In daily use, in order to protect the system components of the speaker, the system components are often installed in a shell to prevent the system components from being invaded by dust and thus shortening their lifespan.

[0004] Common portable speakers are small in size, so the control knobs are often set on the outer surface of the speakers. If it rains suddenly during outdoor use, it is necessary to use rainproof materials to cover the speakers to prevent rain from entering the shell and causing short circuits in system components and malfunctions. When carrying speakers out for use, carrying additional rainproof materials will reduce the portability of the speakers, and they will also need to be assembled when it rains, and the speakers will still be exposed to rain during the assembly process.

[0005] Therefore, we propose a new housing structure for speakers. Utility Model Content

[0006] The main purpose of the utility model is to provide a new shell structure of a speaker, which can quickly form a rainproof structure when it rains when carried out for use, to prevent rainwater from invading the speaker casing and causing adverse interference to the components of the speaker system. There is no need to carry additional rainproof devices, and it is more convenient to use when going out, which can effectively solve the problems in the background technology.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A novel housing structure of an audio system, comprising an audio system shell, and side panels fitted on both sides of the audio system shell, a control panel being mounted on the upper surface of the audio system shell, a handle being rotatably mounted between the side walls of the side panels via a damping shaft, a receiving groove being arranged inside the handle, and a shielding component being arranged in the receiving groove to shield the control panel after being pulled out, both side outer walls of the audio system shell being fixed with limit blocks, and the side walls of the limit blocks being arranged with openings arranged obliquely downward;

[0009] A sound outlet baffle is nested and installed on one side outer wall of the speaker housing, and a splash-proof component is arranged between the bottom and the side wall of the speaker housing.

[0010] Furthermore, the shielding component includes a torsion rotating shaft arranged in the accommodating groove, the outer periphery of the torsion rotating shaft is wrapped with a rainproof tarpaulin, and the edge side of the rainproof tarpaulin is bonded and fixed with a pull rod for conveniently pulling the rainproof tarpaulin to move, and the diameter of the pull rod is smaller than the width of the opening.

[0011] Furthermore, the splash-proof component includes a second transmission rod rotatably set on the inner wall of the audio shell, the two ends of the second transmission rod are respectively rotatably connected to the end of the first transmission rod and the side wall of the support plate passing through the bottom of the audio shell, the bottom of the audio shell is configured with a rotation groove, the support plate is rotatably set on the inner wall of the audio shell, and the side wall of the audio shell is penetrated by a plug rod inserted into the side wall of the support plate, the end of the first transmission rod is rotatably connected to the side wall of the side baffle, and the side wall of the audio shell is configured with a storage groove adapted to the side baffle.

[0012] Furthermore, water guide bars are fixed on both sides of the acoustic housing, and water guide end blocks are fixedly installed on both ends of the water guide bars, and a communicating water guide groove is constructed between the surfaces of the water guide bars and the water guide end blocks.

[0013] Furthermore, the splash-proof component also includes a storage frame fixed to the inner wall of the speaker housing, and a flexible rain shield is bonded between the inner wall of the storage frame and the side wall of the side baffle.

[0014] Furthermore, a plurality of semicircular grooves are constructed on the surface and bottom surface of the handle, and the edge sides of the semicircular grooves are flush with the edge sides of the handle.

[0015] Furthermore, the side wall of the side panel is configured with a microphone storage slot, and the side panel is rotatably provided with a rotating bracket located in the microphone storage slot.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] The new shell structure of the speaker can store the rainproof material inside the handle through the shielding component. When it rains suddenly during the use of the speaker, the pull rod can be pulled quickly and timely to unfold the rainproof tarpaulin. The pull rod is placed in the opening of the limit block, and the rainproof tarpaulin can be stretched straight and unfolded under the action of the torsion rotary shaft to form a shield above the sound outlet baffle, so as to prevent rain from invading the speaker shell and causing adverse interference to the components of the sound system. It is convenient to use on rainy days, and there is no need to carry additional rainproof devices, so it is more convenient to use when going out.

[0018] The new shell structure of the speaker has a splash-proof component. When the plug rod is pulled out and the speaker shell is placed on the ground, the support plate can automatically rotate inward, thereby pushing the side baffles outward. This can not only prevent water from splashing on the speaker shell when it rains, but also play a certain protective role and provide protection when it is hit by external impact.
