[0001] The utility model relates to the technical field of sound amplification and sound conduction, in particular to a reflection tube structure suitable for high-power sound amplification equipment. Background Art

[0002] A sound amplification device is an electronic device that is mainly used to amplify sound and spread it over a wider range. Using a sound amplification device in an open public place allows more people to clearly hear the content being played. A sound amplification device is usually composed of amplifiers, speakers, microphones and other components. It can amplify and process the received sound signals through the amplifier and then output them, so as to expand and spread the sound within a certain range. Sound amplification equipment is widely used in many occasions, such as farms, fields, streets, squares, platforms, factories and other open public places. Sound amplification equipment can improve the clarity and volume of sound, enhance the transmission effect of information, and bring convenience to people's lives and work.

[0003] Most of the existing sound amplification equipment on the market have a reflector in the middle for improving the sound quality and enhancing the sound propagation effect. The reflector can reflect the sound waves emitted by the sound-generating device through the inner wall of the reflector for many times to enhance the volume and expand the sound wave propagation range. The shape and structure of the reflector determine the sound amplification effect of the reflector. The existing reflector is suitable for low power (below 100W) with ideal sound quality and clear broadcasting effect. However, the broadcasting effect is not ideal for high power (above 150W) sound amplification equipment, especially in actual use of large-scale and long-distance broadcasting, the sound quality is poor and the sound is fuzzy.

[0004] In view of the above shortcomings, we need to develop a reflector tube structure suitable for high-power sound amplification equipment to meet the needs of the majority of users. Utility Model Content

[0005] In view of the above-mentioned problems that the reflector tube used in the existing high-power sound amplification equipment has poor sound quality, fuzzy sound, unsatisfactory broadcasting effect, etc. in actual use of large-scale and long-distance broadcasting, the technical solution adopted by the utility model to solve the technical problems is:

[0006] A reflector cylinder structure suitable for high-power sound amplification equipment, comprising an outer cylinder member and an inner cylinder member, wherein the outer cylinder member is provided with an outer cylinder cavity for the inner cylinder member to extend into, the outer cylinder cavity is provided with an outer cylinder opening communicating with the outside, one end of the inner cylinder member is provided with a mounting base, and the mounting base is detachably connected to the outer cylinder opening;

[0007] The inner cylinder is provided with a sound cylinder having one side fixedly connected to the mounting base and the other side extending away from the mounting base, the diameter of the sound cylinder close to the mounting base is diameter A, the diameter of the sound cylinder away from the mounting base is diameter B, and diameter B>diameter A.

[0008] Further, the diameter of the outer cylinder member at a side close to the outer cylinder opening is diameter C, the diameter of the outer cylinder member at a side away from the outer cylinder opening is diameter D, and diameter C>diameter D.

[0009] Furthermore, a waveguide cavity for guiding the transmission direction of sound waves is provided on a side of the outer cylinder away from the outer cylinder opening, and the waveguide cavity is recessed toward the inside of the outer cylinder cavity.

[0010] Furthermore, the mounting base is provided with a plurality of connecting brackets for connecting the outer cylinder member, the connecting brackets extend from the mounting base toward one side of the sound cylinder, the connecting brackets are provided with connecting holes, the outer cylinder member is provided with a matching hole on one side close to the outer cylinder mouth, and the connecting holes are matched and connected with the matching holes.

[0011] Furthermore, the connecting bracket is provided with a bracket step for limiting the installation position of the outer cylinder member, so that the distance between the outer cylinder opening and the side of the mounting base close to the outer cylinder member is in the range of 30 mm-35 mm.

[0012] Furthermore, the mounting base is provided with a throat for conducting sound, the throat passes through the mounting base, and the inner hole diameter of the throat is in the range of 26mm-32mm.

[0013] Furthermore, a cushioning pad for improving sound quality is fixedly connected to a side of the mounting base away from the sound tube.

[0014] Furthermore, the total length of the inner cylinder is length G, the length range of length G is 350mm-360mm, the length of the sound cylinder extending out of the mounting base is length H, and the length range of length H is 315mm-325mm.

[0015] Furthermore, the mounting base is provided with a connecting seat for connecting the sound cylinder, and the connecting seat is a truncated cone structure.

[0016] Furthermore, the connecting seat is provided with an arc surface shape which is smoothly connected to the mounting base, and the arc surface shape is bent toward the center of the mounting base.

[0017] The beneficial effects of the utility model are as follows:

[0018] 1. The outer cylinder and inner cylinder of the utility model can be used in high-power sound amplification equipment after being used together. After the sound emitted by the sound-generating device is processed by the sound cylinder and the outer cylinder, the sound waves are strengthened by the sound cylinder and the outer cylinder cavity, which can increase the volume and transmission quality of the sound, thereby achieving the effect of amplifying the volume and improving the sound quality.

[0019] 2. The utility model has been continuously adjusted after many tests, and the taper, angle and external dimensions of the components of each part of the reflector tube structure are limited. When the reflector tube structure is made with the taper, angle and external dimensions within these ranges, the sound quality and volume of the output sound are relatively ideal in actual use, and the sound is loud and clear, further ensuring the volume and sound quality output by the reflector tube structure.

[0029] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0030] like Figures 1 to 9As shown, a reflector cylinder structure suitable for high-power sound amplification equipment includes an outer cylinder member 1 and an inner cylinder member 2, wherein the outer cylinder member 1 is provided with an outer cylinder cavity 11 for the inner cylinder member 2 to extend into, and the outer cylinder cavity 11 is provided with an outer cylinder opening 12 communicated with the outside, and one end of the inner cylinder member 2 is provided with a mounting base 21, and the mounting base 21 is detachably connected to the outer cylinder opening 12, and the inner cylinder member 2 is provided with a sound cylinder 22 whose one side is fixedly connected to the mounting base 21 and the other side extends away from the mounting base 21, and the diameter of the sound cylinder 22 close to the mounting base 21 is diameter A, and the diameter of the sound cylinder 22 away from the mounting base 21 is diameter B, and diameter B>diameter A.

[0031] The diameter of the side of the acoustic tube 22 close to the mounting base 21 shown in the figure is dimension A, and the diameter of the side of the acoustic tube 22 away from the mounting base 21 is dimension B;

[0032] Optionally, the reflector tube structure can be made of one or more materials such as plastic, metal, wood, and ore. Preferably, the reflector tube structure uses plastic and metal as the main manufacturing materials. The reflector tube structure made of metal can better reflect and guide sound waves, thereby enhancing the sound propagation effect. The surface of the metal material is smooth and has a high reflectivity, which can reduce the loss of sound energy, make the sound propagate over a longer distance, and maintain clarity and intensity during the propagation process. Due to the high density and firmness of the metal material, the sound reflection and resonance effects inside the horn are more significant, thereby enhancing the loudness and sound quality of the sound; and the reflector tube structure made of plastic is usually lighter than metal, and plastic materials are usually cheaper than metal. Using a plastic shell can reduce manufacturing costs, so a horn with a plastic shell is easier to carry and install, and plastic materials are easy to process into various shapes and sizes, so the shape of the horn can be more flexibly designed and customized to meet the requirements of different needs and application scenarios.

[0033] Specifically, in some embodiments, the reflection tube structure is installed on the sound-generating device of the sound amplifying equipment. After the sound-generating device converts the electrical signal into sound and outputs it to the reflection tube structure, it is amplified by the reflection tube structure and diffused to a farther range. The sound output of the high-power sound amplifying equipment requires that the reflection tube structure have a certain size of reflection space and resonance space to ensure the clarity of sound quality on the basis of amplifying the volume. The reflection tube structure includes an outer tube member 1 and an inner tube member 2 for enhancing the volume and improving the sound quality. The inner tube member 2 is provided with a mounting base 21 for mounting the outer tube member 1. The mounting base 21 extends toward one side of the outer tube member 1 with a sound tube 22 for enhancing the sound quality. One end of the sound tube 22 extends into the outer tube cavity 11. The sound tube 22 adopts a hollow thin-walled cylindrical shape. The thin-wall thickness of the sound tube 22 is controlled within 5 mm. The outer tube member 1 also adopts a thin-walled design. The thin-wall thickness of the outer tube member 1 is controlled within 3 mm. The outer shape of the sound cylinder 22 has an inclined taper. The diameter of the sound cylinder 22 on the side close to the mounting base 21 is diameter A, and the diameter of the sound cylinder 22 on the side away from the mounting base 21 is diameter B. The inclination direction of the sound cylinder 22 satisfies diameter B>diameter A. Preferably, the size range of diameter A can be controlled between 25mm and 30mm, and the size range of diameter B can be controlled between 50mm and 55mm. The sound quality and volume guided out within these diameter ranges are ideal. The taper range of the sound cylinder 22 is between 1:13 and 1:15. The sound cylinder 22 is provided with a sound guide cavity 221. One end of the sound guide cavity 221 is connected to the channel of the mounting base 21 for sound generation, and the other end of the sound guide cavity 221 is connected to the outer cylinder cavity 11. When the sound generating device of the sound amplification equipment outputs sound, it is transmitted to the outer cylinder cavity 11 through the sound guide cavity 221 for reflection and resonance to achieve the effect of amplifying the volume and improving the sound quality.

[0034] like Figure 5 and Fig. 9 As shown, the diameter of the outer cylinder member 1 close to the outer cylinder opening 12 is diameter C, the diameter of the outer cylinder member 1 away from the outer cylinder opening 12 is diameter D, and diameter C>diameter D.

[0035] The diameter of the outer cylinder member 1 shown in the figure on the side close to the outer cylinder opening 12 is dimension C, and the diameter of the outer cylinder member 1 on the side away from the outer cylinder opening 12 is dimension D;

[0036] Specifically, in some embodiments, the outer shape of the outer cylinder member 1 also has an inclined taper, and the inclination direction is opposite to the sound cylinder 22. Such a design helps to guide the propagation direction of the sound waves, making the sound waves more concentrated, and the amplification and resonance effects are better. The diameter size of the side close to the outer cylinder mouth 12 is diameter C, and the diameter of the side of the outer cylinder member 1 away from the outer cylinder mouth 12 is diameter D. The inclination direction of the outer cylinder member 1 satisfies diameter C>diameter D. Preferably, the size range of diameter C can be controlled between 100mm and 110mm, and the size range of diameter D can be controlled between 70mm and 80mm. The sound quality and volume guided out within these diameter ranges are more ideal.

[0037] like Figure 1 , Figure 2 , Figure 5 , Figure 7 and Fig. 9 As shown, a waveguide cavity 13 for guiding the transmission direction of sound waves is provided on a side of the outer cylinder member 1 away from the outer cylinder opening 12 , and the waveguide cavity 13 is recessed toward the inside of the outer cylinder cavity 11 .

[0038] Specifically, in some embodiments, the waveguide cavity 13 is arranged at a position of the outer cylinder 1 close to the sound cylinder 22 for outputting sound. The waveguide cavity 13 is conical and recessed toward the sound cylinder 22. A waveguide step 131 recessed toward the sound cylinder 22 is also provided around the waveguide cavity 13. When the sound-generating device of the sound amplification equipment outputs sound, it is transmitted to the outer cylinder cavity 11 through the sound guide cavity 221. The waveguide cavity 13 and the waveguide step 131 reflect and guide the sound waves to the cavity wall of the outer cylinder cavity 11. Without the design of the waveguide cavity 13 and the waveguide step 131, the sound waves will easily be reflected back into the sound guide cavity 221, which will easily cause the loss of the sound waves. After adding the design of the waveguide cavity 13 and the waveguide step 131, the sound waves will be reflected directionally to the cavity wall of the outer cylinder cavity 11 and undergo multiple reflections and resonances, further enhancing the volume and improving the sound quality.

[0039] More specifically, the angle range of the conical cross-sectional angle M of the waveguide cavity 13 is between 60 degrees and 150 degrees. The sound waves reflected by the waveguide cavity 13 within this cross-sectional angle range can better contact the cavity wall of the outer cylinder cavity 11, further enhancing the volume and improving the sound quality.

[0040] like Figures 1 to 9 As shown, the mounting base 21 is provided with a plurality of connecting brackets 211 for connecting the outer cylinder member 1, the connecting brackets 211 extend from the mounting base 21 toward one side of the sound cylinder 22, the connecting brackets 211 are provided with connecting holes 213, and the outer cylinder member 1 is provided with a matching hole 14 on one side close to the outer cylinder mouth 12, and the connecting hole 213 is matched and connected with the matching hole 14.

[0041] Specifically, in some embodiments, the connecting bracket 211 extends from the mounting base 21 toward the outer cylinder 1. The connecting bracket 211 is arranged at intervals around the sound cylinder 22 at the edge of the mounting base 21 close to the outside, and plays a role in uniformly supporting the outer cylinder 1. No matter which direction the reflector cylinder structure emits sound, the connecting bracket 211 can stabilize the position of the outer cylinder 1 on the mounting base 2. A connecting reinforcement rib 214 is provided at the intersection of the connecting bracket 211 and the mounting base 2. The connecting reinforcement rib 214 is located between the sound cylinder 22 and the connecting bracket 211. The connecting bracket 211 further strengthens its own stability through the connecting reinforcement rib 214, reduces the shaking effect caused by the weight of the outer cylinder 1, and the stable installation can further ensure the volume and sound quality.

[0042] Optionally, the number of connecting brackets 211 is controlled to be 3 to 4. Too few connecting brackets 211 may cause unstable installation of the outer cylinder member 1, which may have the risk of shaking and swinging. Too many connecting brackets 211 may cause dense arrangement, which may affect the volume and quality of the sound waves. Controlling the number of connecting brackets 211 to 3 to 4 can take into account both the stable installation of the outer cylinder member 1 and the maximization of the volume and quality of the sound waves, thereby ensuring the normal use of the reflector tube structure.

[0043] like Figure 5 As shown, the connecting bracket 211 is provided with a bracket step 212 for limiting the installation position of the outer cylinder member 1, so that the distance between the outer cylinder opening 12 and the side of the mounting base 21 close to the outer cylinder member 1 is in the range of 30mm-35mm.

[0044] Specifically, in some embodiments, the bracket step 212 is located at the connection between the connecting bracket 211 and the outer cylinder member 1, and the bracket step 212 is recessed in the direction of the sound cylinder 22. When the outer cylinder member 1 is installed in the connecting bracket 211, it contacts the bracket step 212, so that the bracket step 212 limits the position between the outer cylinder member 1 and the root of the connecting bracket 211, thereby limiting the position between the outer cylinder member 1 and the mounting base 2. The reserved space and distance between the outer cylinder member 1 and the mounting base 2 affect the volume and quality of the sound waves. If the reserved distance is too small, the sound waves are difficult to transmit. If the reserved distance is too large, the sound waves are easily consumed and weakened. Preferably, the distance range between the outer cylinder member 1 and the mounting base 21 is controlled between 30 mm and 35 mm. The sound quality and volume within this distance range are ideal, which facilitates the reflection cylinder structure to further control the volume and sound quality.

[0045] like Figure 5 , Figure 6 and Fig. 9 As shown, the mounting base 21 is provided with a throat 218 for conducting sound, the throat 218 passes through the mounting base 21, and the inner hole diameter of the throat 218 ranges from 26 mm to 32 mm.

[0046] The inner diameter of the throat 218 shown in the figure is dimension F.

[0047] Specifically, in some embodiments, the throat opening 218 is located in the middle of the mounting base 21 and passes through the upper and lower sides of the mounting base 21. One end of the throat opening 218 is connected to the sound-generating device of the sound amplifier, and the other end of the throat opening 218 is connected to the sound-conducting cavity 221 of the sound cylinder 22. The inner wall of the throat opening 218 is smoothly connected to the inner wall of the sound-conducting cavity 221. When the sound-generating device of the sound amplifier outputs sound, it is transmitted to the sound-conducting cavity 221 and the outer cylinder cavity 11 through the throat opening 218 for reflection and resonance to achieve the effect of amplifying the volume and improving the sound quality. More specifically, the sound quality and volume are more ideal when the inner hole diameter range of the throat opening 218 is controlled between 26 mm and 32 mm, which facilitates the reflection cylinder structure to further control the volume and sound quality.

[0048] More specifically, a base screw hole 219 is provided on the side of the throat 218 away from the sound cylinder 22. The base screw hole 219 is provided with a threaded design for detachable connection to the sound amplification device. The throat 218 is detachably connected to the sound amplification device through the thread, which facilitates the maintenance and replacement of the reflector cylinder structure after long-term use.

[0049] like Figures 3 to 6 as well as Figure 8 and Fig. 9 As shown, a cushioning cotton pad 217 for improving sound quality is fixedly connected to one side of the mounting base 21 away from the sound tube 22 .

[0050] Specifically, in some embodiments, the buffer cotton pad 217 is located on the side of the mounting base 21 that is used to contact the sound amplification device. After the existing reflector tube structure is installed on the sound amplification device, the sound amplification device will inevitably generate certain vibrations when it is in operation. However, the reflector tube structure will be in close contact with the sound amplification device for installation and fastening. At this time, the vibration of the sound amplification device will affect the output volume and sound quality of the reflector tube structure. In this embodiment, the buffer cotton pad 217 can be made of sponge, rubber, animal fur, artificial leather, soft plastic and other materials that can play a shock-absorbing role. The buffer cotton pad 217 is set between the mounting base 21 and the sound amplification device, which can reduce and reduce the impact of the vibration of the sound amplification device itself on the reflector tube structure, thereby further ensuring the volume and sound quality.

[0051] like Figure 5 and Fig. 9 As shown, the total length of the inner cylinder 2 is length G, and the length range of length G is 350mm-360mm. The length of the sound cylinder 22 extending from the mounting base 21 is length H, and the length range of length H is 315mm-325mm.

[0052] The total length of the inner cylinder 2 shown in the figure is dimension G, and the length of the sound cylinder 22 extending out of the mounting base 21 is dimension H;

[0053] Specifically, in some embodiments, the length of the inner cylinder member 2 will affect the amplification and resonance effect of the sound waves. If the inner cylinder member 2 is designed to be too short, the sound waves will not have enough space to reflect and resonate, resulting in a decrease in volume and sound quality. If the inner cylinder member 2 is designed to be too long, the sound waves will be consumed excessively during the reflection and resonance process, resulting in a decrease in volume and sound quality. The total length of the inner cylinder member 2 is formed by the height of the mounting base 2 and the length of the sound cylinder member 22. The sound cylinder 22 will extend into the mounting base 2 for a certain distance to ensure that the sound cylinder 22 can be firmly installed on the mounting base 2. More specifically, the length range of the sound cylinder 22 extending from the mounting base 21 is controlled to be between 315 mm and 325 mm. The total length of the inner cylinder member 2 can be determined only after the sound cylinder 22 is installed. The total length range of the inner cylinder member 2 is controlled to be between 350 mm and 360 mm.

[0054] like Figures 1 to 6 As shown, the specific implementation of Example 1 of the utility model is as follows:

[0055] The reflector tube structure is installed on the sound amplification device through the base screw hole 219 and the mounting screw hole 215 of the mounting base 2. The end of the sound tube 22 with a smaller diameter extends into the throat opening 218 and is tightly fixedly connected to the mounting base 2. The end of the sound tube 22 with a larger diameter extends into the outer tube member 1, so that the sound tube 22 is placed in the outer tube cavity 11, and the outer tube opening 12 is close to the connecting bracket 211, so that the connecting hole 213 is aligned with the matching hole 14, and a screw is passed through the matching hole 14 and matched with the connecting hole 213 to complete the installation of the reflector tube structure.

[0056] When the sound-generating device of the sound amplifying equipment outputs sound, the sound wave is transmitted to the sound-guiding cavity 221 through the throat 218. After being reflected by the wave-guiding cavity 13, the sound wave contacts the cavity wall of the outer cylinder cavity 11 and reflects and resonates. The sound wave is reflected from the cavity wall of the outer cylinder cavity 11 to the surface of the connecting socket 3. The sound wave will be output to the outside with lower loss, thereby achieving the effect of amplifying the volume and improving the sound quality.

[0057] like Figures 7 to 9 As shown, the specific implementation of Example 2 of the utility model is as follows:

[0058] Different from Example 1, the outer surface of the connecting seat 3 of this embodiment adopts a smooth curved surface shape 32. When the surface of the connecting seat 3 adopts a smooth curved surface shape 32, the sound waves reflected from the outer cylinder cavity 11 will be reflected to the outside with lower loss by the smooth curved surface shape 32, further ensuring the output sound quality effect and guiding the direction of the sound waves.

[0059] The above examples are only used to further illustrate the technical content of the utility model, so that readers can understand it more easily, but it does not mean that the implementation methods of the utility model are limited to this. Any technical extension or re-creation made based on the utility model is protected by the utility model. The protection scope of the utility model shall be based on the claims.
