TECHNICAL FIELD

[0001] The utility model relates to a loudspeaker technical field, concretely is a kind of reinforced acoustic diffusion loudspeaker shell. BACKGROUND

[0002] Loudspeaker, also known as loudspeaker, is a commonly used electroacoustic transducer, which can be seen in sound-emitting electronic and electrical equipment. Loudspeaker is a transducer that converts electrical signal into acoustic signal. The performance of loudspeaker has a great influence on sound quality. Loudspeaker is the weakest device in sound equipment, but it is the most important component for sound effect. Loudspeaker is divided into built-in loudspeaker and external loudspeaker.

[0003] The existing announcement number CN217656897U proposes a loudspeaker shell with high-efficiency heat dissipation function, which includes a protective cover, a dust screen is fixedly installed on one side of the protective cover, a ventilation mechanism is arranged on the other side of the protective cover, a heat dissipation mechanism is arranged in the ventilation mechanism, a damping mechanism is arranged at the bottom of the inner cavity of the protective cover, a loudspeaker body is fixedly connected to the top of the damping mechanism, a heat dissipation net is formed in the inner part of the protective cover, an activity rod is fixedly connected to the bottom of the protective cover, a telescopic rod is fixedly connected to the inner part of the activity rod, and a contraction spring is installed on the outer part of the telescopic rod. The loudspeaker shell with high-efficiency heat dissipation function can better dissipate heat and adjust the height of the loudspeaker shell at the same time, avoiding the difficulty of heat dissipation and height adjustment of most loudspeaker shells, thereby bringing convenience to the use of the loudspeaker shell.

[0004] When the above-mentioned device is used, the sound produced by the loudspeaker is transmitted out from the cover opening position of the protective cover. Since the sound is concentrated at the cover opening position of the protective cover, the sound intensity in other directions is obviously weakened, which cannot achieve good acoustic diffusion. The coverage of sound in space is uneven, so that the audience can only receive better sound effect at a specific position, thereby affecting the overall listening experience. UTILITY MODEL CONTENTS

[0005] The utility model aims to provide a loudspeaker shell with enhanced acoustic diffusion to solve the problem of poor listening experience caused by the concentration of sound at a specific position when the existing device is used.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a loudspeaker shell with enhanced acoustic diffusion, which comprises a shell and a mounting back plate. The shell is arranged on the front side wall of the mounting back plate. A loudspeaker is fixedly connected to the middle of the front side wall of the mounting back plate, and the loudspeaker is located on the inner side of the shell. Diffusion holes are uniformly formed on the outer side of the shell, and a wooden micro-diffusion plate is arranged in the inner cavity of the diffusion hole.

[0007] The front side wall of the mounting back plate is fixedly connected with a fixed block, and the inner side of the fixed block is fixedly connected with a first fixed elastic block.

[0008] The loudspeaker can strengthen the diffusion of sound in use, make the sound evenly spread in more directions, not concentrate in a specific direction, widen the coverage angle of the loudspeaker, and improve the overall listening experience.

[0009] Preferably, a first annular mounting groove is formed in the inner cavity wall of the diffusion hole, second fixed elastic blocks are fixedly connected to the outer side wall of the wooden micro diffusion plate, and the second fixed elastic blocks are clamped with the inner cavity wall of the first annular mounting groove.

[0010] The first annular mounting groove and the second fixed elastic block can facilitate the installation and disassembly of the wooden micro diffusion plate, thereby facilitating subsequent maintenance.

[0011] Preferably, a cover is fixedly connected to the inner side wall of the wooden micro diffusion plate, and the cover is made of polystyrene material.

[0012] The cover can concentrate sound on the wooden micro diffusion plate, thereby improving the diffusion efficiency and uniformity of sound and optimizing the overall sound quality.

[0013] Preferably, a dust screen is fixedly connected to the inner cavity wall of the diffusion hole.

[0014] The dust screen can effectively prevent dust.

[0015] Preferably, a second annular mounting groove is formed in the rear side of the outer side wall of the shell, and the first fixed elastic block is clamped with the second annular mounting groove.

[0016] The first fixed elastic block and the second annular mounting groove can facilitate the quick disassembly and assembly of the shell and the mounting back plate.

[0017] Preferably, a fixed ring is fixedly connected to the front side wall of the mounting back plate, the loudspeaker is located on the inner side of the fixed ring, an elastic ring is fixedly connected to the outer side wall of the fixed ring, and the outer side wall of the elastic ring is in contact with the inner side wall of the shell.

[0018] The elastic ring and the fixed ring can assist in the installation of the shell during installation and provide auxiliary support after installation, thereby improving the stability of the overall installation.

[0019] Preferably, the first fixed elastic block, the second fixed elastic block, and the elastic ring are all made of polyurethane elastomer material.

[0020] By using polyurethane elastomer to make the first fixed elastic block, the second fixed elastic block, and the elastic ring, the elasticity is excellent and the resilience is high. It can quickly return to the initial state after multiple deformations. While having elasticity, it also has enough hardness to bear the support function and ensure the stability of installation.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. When the speaker is used, the wooden miniature diffuser scatters the incident sound in multiple directions, reducing sound reflection and focusing, reducing echo and reverberation, and making the sound clearer. Then, the diffuser holes make the sound more evenly distributed in space, avoiding the sound from being concentrated in certain specific directions. When the sound is enhanced and diffused, the cover guides the sound in a concentrated manner, thereby improving the diffusion effect.

[0023] 2. This application, through the cooperation of the first fixed elastic block and the fixed block with the second annular mounting groove, enables the quick assembly and disassembly of the housing and mounting back plate, thereby facilitating subsequent maintenance of the speaker. At the same time, the fixed ring and the elastic ring assist in the installation during installation and provide auxiliary support after installation, thereby improving the overall stability of the installation.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example: Figures 1-5 As shown, this utility model provides a technical solution for strengthening the acoustic diffusion speaker housing, including a housing 100 and a mounting back plate 200;

[0032] Please refer to this carefully. Figure 1 , Figure 2 , Figure 3 and Figure 5 The housing 100 is disposed on the front sidewall of the mounting backplate 200. A speaker 110 is fixedly connected to the middle of the front sidewall of the mounting backplate 200, and the speaker 110 is located inside the housing 100. Diffuser holes 111 are evenly distributed on the outer side of the housing 100. A wooden miniature diffuser plate 112 is provided in the inner cavity of the diffuser hole 111. A first annular mounting groove 120 is formed around the inner wall of the diffuser hole 111. Second fixing elastic blocks 121 are fixedly connected to both sides of the outer sidewall of the wooden miniature diffuser plate 112. The second fixing elastic blocks 121 are engaged with the inner wall of the first annular mounting groove 120. The inner wall of the micro diffuser plate 112 is fixedly connected to a cover 130, which is made of polystyrene. The inner wall of the diffusion hole 111 is fixedly connected to a dustproof mesh. When the speaker 110 is in use, the incident sound is scattered in multiple directions through the wooden micro diffuser plate 112, reducing sound reflection and focusing, reducing echo and reverberation, and making the sound clearer. The sound is then distributed more evenly in space through the diffusion hole 111, avoiding the sound from being concentrated in certain specific directions. When the sound is enhanced and diffused, the cover 130 is used to concentrate and guide the sound, thereby improving the diffusion effect.

[0033] Please refer to this carefully. Figures 1-5The four corners of the front side wall of the mounting back plate 200 are fixedly connected with fixed blocks 210, the inner side of the fixed blocks 210 is fixedly connected with first fixed elastic blocks 211, the rear side of the outer side wall of the shell 100 is provided with a second annular mounting groove 140, the first fixed elastic blocks 211 are clamped with the second annular mounting groove 140, the front side wall of the mounting back plate 200 is fixedly connected with a fixed ring 220, the loudspeaker 110 is located on the inner side of the fixed ring 220, the outer side wall of the fixed ring 220 is fixedly connected with an elastic ring 221, the outer side wall of the elastic ring 221 is in contact with the inner side wall of the shell 100, the first fixed elastic blocks 211, the second fixed elastic blocks 121 and the elastic ring 221 are all made of polyurethane elastomer material, the first fixed elastic blocks 211 and the fixed blocks 210 cooperate with the second annular mounting groove 140, so that the shell 100 and the mounting back plate 200 can be quickly disassembled and assembled, thereby facilitating the subsequent maintenance of the loudspeaker 110, and meanwhile, the fixed ring 220 cooperates with the elastic ring 221 to assist in mounting during installation and to assist in supporting after installation, so that the stability of the overall installation is improved.

[0034] In use, when the loudspeaker 110 plays sound, part of the sound is diffused to the front part through the loudspeaker mesh cover at the front part of the shell 100, and part of the sound is guided to the wooden micro diffusion plate 112 after being gathered by the cover body 130. Since the cover body 130 is made of polystyrene material, the smooth inner wall thereof can reduce sound reflection loss, so that the sound is more concentrated on the wooden micro diffusion plate 112. The wooden micro diffusion plate 112 refracts and diffuses the concentrated sound, scatters the incident sound in multiple directions, reduces sound reflection and focusing, reduces echo and reverberation, makes the sound clearer, and then transmits the sound through the diffusion hole 111 to make the sound more evenly distributed in space, avoids the concentration of sound in certain specific directions, thereby strengthening the diffusion of acoustics, enabling listeners at each position to receive relatively balanced sound, improving the uniformity of sound propagation, and simultaneously, the diffusion hole 111 can also dissipate heat of the loudspeaker 110 during use, thereby improving the use effect of the loudspeaker 110.

[0035] When the speaker 110 needs to be maintained, the shell 100 is only pulled with force, the shell 100 drives the first fixed elastic block 211 to extrude the second annular mounting groove 140 to generate deformation, so that the first fixed elastic block 211 is separated from the second annular mounting groove 140, thereby the shell 100 is taken off from the mounting back plate 200, the speaker 110 is conveniently maintained, after the shell 100 is taken off, the cover body 130 is pulled, the cover body 130 drives the wooden micro diffusion plate 112 to move, thereby the second fixed elastic block 121 is separated from the first annular mounting groove 120, the wooden micro diffusion plate 112 and the cover body 130 are taken off to be maintained, after the maintenance is completed, the wooden micro diffusion plate 112 and the cover body 130 are installed again, after the speaker 110 is maintained, the shell 100 is sleeved on the elastic ring 221, and then is pressed with force, so that the first fixed elastic block 211 is clamped into the second annular mounting groove 140, after installation, the fixed ring 220 cooperates with the elastic ring 221 to assist supporting the shell 100, thereby the stability of installation is guaranteed.
