DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] The present utility model provides a high-strength speaker structure, as Figures 1-4 shown, which includes a box body 1. The box body 1 is composed of a rear shell 11 and a front shell 12. A protective cover 2 is installed on the outer side of the front of the box body 1 to protect the front. The surface of the protective cover 2 is provided with a mesh structure. A sounding unit 7 is installed on the front of the box body 1, and the sounding unit 7 is embedded in the front shell 12. Limiting plates 121 are installed on the upper and lower sides of the front of the front shell 12. The limiting plates 121 space apart the surface of the protective cover 2 from the sounding unit 7 to prevent the sounding unit 7 from contacting the protective cover 2. A plurality of reinforcing ribs 13 are installed on the inner wall of the box body 1 to improve the structural strength of the box body 1.

[0024] In this embodiment, a control panel 5 is installed on the top of the box body 1 to control the switch of the speaker.

[0025] Specifically, a handle 6 is installed on the top of the box body 1. The handle 6 includes a first half shell 61 and a second half shell 62. The first half shell 61 and the second half shell 62 are fixedly connected by bolts. Both ends of the first half shell 61 and the rear shell 11 are of an integrally formed structure, and both ends of the second half shell 62 and the front shell 12 are of an integrally formed structure, ensuring the strength of the handle 6 so that the handle 6 will not break.

[0026] Furthermore, a fluorescent plate 3 is installed on the upper part of the front of the box body 1 to produce fluorescence at night, which is convenient for determining the position during outdoor use.

[0027] Furthermore, vibration membranes 4 are installed on both sides of the box body 1 to facilitate the transmission of sound to both sides and ensure the stereoscopic effect of sound. A frame 41 is installed on the outer side of the vibration membrane 4. The frame 41 is fixed to the outer wall of the box body 1 by bolts. A hanging hole 42 is provided at the top of the frame 41, which is convenient for lifting with a hanging rope.

[0028] Furthermore, a sound insulation component 8 is installed on the inner side of the back of the box body 1 for sound insulation on the inner side of the back of the box body 1.

[0029] Furthermore, the sound insulation component 8 includes sound insulation cotton 81. The sound insulation cotton 81 is pressed and positioned by a pressing rod 82. Bolting holes 821 are provided at both ends of the pressing rod 82. Both ends of the pressing rod 82 are fixed to the inner wall of the box body 1 by bolts, achieving a good sound insulation effect on the back and preventing the sound of the sounding unit 7 from resonating with the inner wall of the chassis 1.

[0030] Furthermore, support foot pads are installed at the bottom of the cabinet 1 to facilitate the support of the bottom of the cabinet 1.

[0031] When the high-strength speaker structure of the present utility model is in use, first, the speaker is turned on through the control panel 5. The sound generating unit 7 starts to work and generates sound signals. These sound signals are transmitted outward through the openings on the front shell 12. At the same time, the mesh structure on the protective cover 2 allows the sound to be transmitted unobstructed, while preventing external objects from directly contacting the sound generating unit 7, ensuring the safe operation of the speaker.

[0032] During the sound generation process, the reinforcing ribs 13 on the inner wall of the cabinet 1 play a key supporting role. They effectively enhance the structural strength of the cabinet, reduce the resonance and deformation that may occur when the speaker plays at high volume, thereby maintaining the clarity of the sound and the stability of the sound quality.

[0033] At the same time, the sound insulation component 8 plays an important sound insulation role on the inner side of the back of the speaker. The sound insulation cotton 81 is tightly fixed on the inner wall of the cabinet 1 by the pressing rod 82, effectively absorbing the sound waves generated by the sound generating unit 7, preventing the sound from resonating unnecessarily with the inner wall of the cabinet, and further improving the sound quality of the speaker.

[0034] In addition, when the speaker needs to be used outdoors or in different places, the user can conveniently carry or hang the speaker through the handle 6 on the top of the cabinet. The fluorescent plate 3 emits fluorescence when used at night, helping the user quickly locate the speaker in a dim light environment. At the same time, the diaphragm 4 is installed on both sides of the cabinet, effectively spreading the sound to both sides and ensuring the stereo effect of the speaker.

[0035] Finally, it should be noted that for the sound generating unit 7 and other components in this embodiment, the electronic components in the above components are all general standard components or components known to those skilled in the art. Their structures and principles can be known by those skilled in the art through technical manuals or obtained through conventional experimental methods. At the idle places of this device, all the above electrical components are respectively connected by wires. The specific connection means should refer to the working order of each electrical component in the above working principle to complete the electrical connection, which are all well-known technologies in the art.

[0036] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only the preferred examples of the present utility model and are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
