Description

Technical Field

[0001] The utility model relates to the field of sound box structures, in particular to a high-power cabinet-type sound box which is easy to assemble. Background Art

[0002] A speaker is a device that can convert audio signals into sound. In layman's terms, it means that the speaker main box or subwoofer box has a built-in power amplifier, which amplifies the audio signal and then plays it back through the speaker itself, making the sound louder.

[0003] At present, cabinet speakers are widely seen by the public. They are a type of speaker set with a structure similar to a cabinet. They are generally used as fixed indoor speakers. They have a large sound field and a shocking listening experience. The structure of a cabinet speaker is mainly composed of an external frame shell and internal speaker components, and the speaker unit and the external shell are fixedly connected (for example, the speaker unit and the outermost protective cover of the unit), including welding, gluing, etc. Therefore, whether it is assembly or disassembly, there is a certain degree of difficulty (tedious), especially when there are many speaker units.

[0004] In view of this, the present technical solution proposes a high-power cabinet speaker that is easy to assemble. It adopts a modular assembly structure, and the speaker unit and the front and rear shells are all independent components. All of them can be quickly and easily installed and disassembled, especially for some speaker structures with more speaker units, which greatly improves the efficiency of their installation and disassembly maintenance. Utility Model Content

[0005] The technical solution of the utility model aims to solve at least one of the technical problems in the related art to a certain extent. To this end, the main purpose of the utility model is to provide a high-power cabinet speaker that is easy to assemble, aiming to solve the problem that the cabinet speaker structure in the prior art does not have a modular assembly structure, and the installation, disassembly and maintenance work are cumbersome and inefficient.

[0006] To achieve the above object, the utility model provides a high-power cabinet-type speaker that is easy to assemble, including a speaker body consisting of a speaker unit, a front frame and a back frame.

[0007] The front frame and the back frame are both detachable structures. A protective cover corresponding to the speaker unit is provided on the front frame. A plastic shell for connecting with the front frame is formed around the protective cover. A fixing piece is provided on the plastic shell. A fixing sleeve matching with the fixing piece is provided on the inner wall of the back frame. A fixing plate fitting with the back of the plastic shell is formed around the speaker unit, and through holes corresponding to the fixing piece and the fixing sleeve are opened on the fixing plate.

[0008] As a further solution of the present utility model, each of the speaker units is arranged in a top-down manner, and the plastic shells adjacent to each other on the upper and lower sides are connected into an integral shell structure.

[0009] As a further solution of the present utility model, guide posts corresponding to the fixing members are provided inside the front frame.

[0010] As a further solution of the present utility model, hanging holes for hoisting are provided at the top of the back frame.

[0011] As a further solution of the present utility model, the fixing member is a bolt, and fixing holes for fastening the bolt are provided on the back of the back frame.

Description of the reference numerals of the main components / assemblies

[0023] Reference numeral Name Reference numeral Name 1 Loudspeaker body 110 Hanging hole 10 Front frame 111 Fixed sleeve 100 Protective cover 112 Fixing hole 101 Plastic shell 113 Wiring harness 102 Fastening piece 114 Inlet hole 103 Footrest 12 Sound emitting unit 104 Guide post 120 Fixing plate 11 Rear frame 121 Through hole Specific embodiments

[0024] Are as follows:

[0025] Please refer to the attached Figure 1-5 ,

[0026] The main structure includes a speaker main body 1 composed of a speaker unit 12, a front frame 10 and a back frame 11. Both the front frame 10 and the back frame 11 are detachable structures. A protective cover 100 corresponding to the speaker unit 12 is provided on the front frame 10. A plastic shell 101 for connecting with the front frame 10 is formed around the protective cover 100. A fixing member 102 is provided on the plastic shell 101. A fixing sleeve 111 cooperating with the fixing member 102 is provided on the inner wall of the back frame 11. A fixing plate 120 fitting with the back of the plastic shell 101 is formed around the speaker unit 12, and through holes 121 corresponding to the fixing member 102 and the fixing sleeve 111 are formed on the fixing plate 120.

[0027] The working principle is as follows:

[0028] During installation, first preliminarily fix the speaker unit 12 (which can be an array composed of multiple speaker units 12) to the front frame 10 (by using the cooperation of the fixing member 102 and the through hole 121), and then fix the front frame 10 and the speaker unit 12 together on the fixing sleeve 111 of the back frame 11 to complete the assembly. When disassembly and maintenance are required, directly remove the fixing member 102 to complete the separation of the speaker unit 12, without the need for complex separation steps (such as chemical welding, wire cutting and degumming, etc.). The protective cover 100 is connected to the front frame 10 by the plastic shell 101, and the plastic shell 101 can also be set as a structure integrated with the front frame 10. This modular speaker structure neither needs to change the original speaker assembly structure nor simplifies the speaker assembly and disassembly steps.

[0029] A preferred embodiment of the present utility model: Each speaker unit 12 is arranged in a vertical row, and the plastic shells 101 adjacent to the upper and lower sides are connected into an integral shell structure.

[0030] The plastic shell 101 is a frame shell integrated with the front frame 10. Fixing members 102 are formed on the plastic shell 101, and the speaker unit 12 is fixed through these fixing members 102.

[0031] A preferred embodiment of the present utility model: Guide posts 104 corresponding to the fixing members 102 are provided inside the front frame 10.

[0032] The function of the guide post 104 is to provide a penetration trajectory for the fixing member 102 and prevent the path of the fixing member 102 from skewing.

[0033] A preferred embodiment of the present utility model: A hanging hole 110 for hoisting is provided at the top of the back frame 11.

[0034] The cabinet-type speaker can also be hung. For example, the entire speaker main body 1 is hoisted (hung) at a position close to the ceiling of the indoor corner through the hanging hole 110.

[0035] A preferred embodiment of the present utility model: The fixing member 102 is a bolt, and a fixing hole 112 for fastening the bolt is provided on the back of the back frame 11.

[0036] A preferred embodiment of the present utility model: Foot seats 103 are provided at the bottom of the front frame 10.

[0037] A preferred embodiment of the present utility model: A wire harness 113 connected to each speaker unit 12 is provided in the wire inlet hole 114.

[0038] The above are only the preferred embodiments of the technical solution of the present utility model, and do not limit the patent scope of the technical solution of the present utility model. Any equivalent structural transformation made under the inventive concept of the technical solution of the present utility model by using the description and drawings of the technical solution of the present utility model, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the technical solution of the present utility model.
