Description

Technical Field

[0001] This utility model relates to a horn tube, and more specifically, to an integrated horn tube. Background Technology

[0002] Megaphones have some applications in police work. For example, in certain special circumstances, police officers can use megaphones to issue emergency notices, evacuate crowds, or direct traffic; the portability and sound transmission range of megaphones make them practical in police equipment.

[0003] Traditional horn tubes are often large and not portable. Their internal structure is relatively complex, requiring more parts and connections, which increases manufacturing and maintenance costs.

[0004] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an integrated horn tube.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an integrated horn tube, characterized in that: it includes a horn tube body, a horn base is provided on one side of the horn tube body, a horn chamber for placing the horn is provided inside the horn base, a diffuser is provided at the top of the horn chamber, flow ports are provided on both sides of the horn base, an amplifier is provided on the other side of the horn tube body, the diffuser, flow ports and amplifier form a sound flow channel, and an echo tube is provided inside the horn base.

[0007] By employing the above technical solutions: the diffuser opening at the top of the speaker chamber helps the sound to diffuse more widely after it is emitted from the speaker; the sound conduit formed by the flow port and the amplifier provides a smooth conduction path for the sound. This helps reduce the attenuation of sound during propagation; the echo tube installed inside the speaker base can capture and reflect part of the sound, superimposing it with the sound directly emitted from the speaker, thereby enhancing the sound intensity.

[0008] The present invention is further configured such that: one side of the echo tube is fixedly connected to the inner wall of the speaker base, and the other side is fixedly connected to the speaker cavity.

[0009] The present invention is further configured such that: two first channel columns are fixedly connected to the inner wall of the speaker base, and the two first channel columns are respectively located on both sides of the speaker cavity.

[0010] The present invention is further configured such that: a second channel column extends from the top of the echo tube toward the side of the speaker chamber, and the second channel column is fixedly connected to the top of the speaker chamber.

[0011] The present invention is further configured such that the surface of the speaker base is provided with two echo ramps.

[0012] The present invention is further configured such that a parts groove is provided on the top of the speaker body.

[0013] The present invention has the following beneficial effects: 1. The diffusion port opened at the top of the speaker chamber, the flow ports on both sides of the speaker base, and the amplifier tube together form a sound flow channel. This design helps the sound to spread and diffuse smoothly, so that the sound can be distributed more evenly to the surrounding environment.

[0014] 2. The fixed connection between the top of the echo tube and the inner wall of the speaker base, as well as the fixed connection between the second channel column and the top of the speaker chamber, enhance the overall stability of the speaker tube.

[0015] 3. The echo tube and second channel column can capture and reflect sound more effectively, allowing the reflected sound to enter the sound circulation channel more efficiently, making the overall sound louder. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0022] like Figures 1 to 3As shown, the integrated horn tube includes a horn tube body 1, a horn base 2 is provided on one side of the horn tube body 1, a horn chamber 3 for placing the horn is provided inside the horn base 2, a diffuser 4 is provided on the top of the horn chamber 3, flow ports 6 are provided on both sides of the horn base 2, and an amplifier 5 is provided on the other side of the horn tube body 1. The diffuser 4, flow ports 6 and amplifier 5 form a sound flow channel, and an echo tube 7 is provided inside the horn base 2.

[0023] The speaker chamber 3 provides space for the speaker. When the speaker (not shown in the figure) starts to work, the sound emitted by the speaker (not shown in the figure) flows out through the diffuser 4. The flow port 6 is located on both sides of the speaker base 2 and on both sides of the speaker chamber 3. After the sound emitted by the speaker flows out through the diffuser 4, it reaches the amplifier tube 5 through the flow port 6. The echo tube 7 is designed with a slope. At the same time, the echo tube 7 can also make some of the sound in the speaker tube body 1 bounce back into the sound flow pipe, achieving a louder sound effect.

[0024] The diffuser vent 4 at the top of the speaker chamber 3 helps the sound to diffuse more widely after it is emitted from the speaker; the sound conduit formed by the flow port 6 and the amplifier tube 5 provides a smooth conduction path for the sound. This helps reduce the attenuation of the sound during propagation; the echo tube 7 set inside the speaker base 2 can capture and reflect part of the sound, superimposing it with the sound directly emitted from the speaker, thereby enhancing the intensity of the sound.

[0025] One side of the echo cylinder 7 is fixedly connected to the inner wall of the speaker base 2, and the other side is fixedly connected to the speaker chamber 3. The design of the echo cylinder 7 can capture part of the sound emitted by the speaker and reflect it into the sound flow channel. The fixed connection between the echo cylinder 7 and the speaker base 2 provides additional support and stability to the entire speaker structure. This connection method helps to reduce the occurrence of vibration and resonance, ensuring that the speaker can maintain stable performance during long-term use.

[0026] Two first channel posts 8 are fixedly connected to the inner wall of the speaker base 2. The two first channel posts 8 are located on both sides of the speaker chamber 3. The first channel posts 8 can further limit the sound flow channel, forming a narrower space. Narrow space tuning reduces the spatial sense and width of the sound, making the sound more focused and limited.

[0027] The top of the echo tube 7 extends to the side facing the speaker chamber 3, and the second channel column 9 is fixedly connected to the top of the speaker chamber 3.

[0028] The second channel column 9 extends to a position close to the diffuser 4, and works in conjunction with components such as the first channel column 8 to further define the sound flow path. At the same time, the second channel column 9 works in conjunction with the echo tube 7 to allow the reflected sound to enter the sound flow channel more effectively.

[0029] The surface of the speaker base 2 is provided with two echo ramps 10; the echo ramps are located inside the amplifier tube and can cooperate with the amplifier tube. The echo ramps 10 can capture and reflect part of the sound from the amplifier tube 5, which improves the efficiency of sound utilization, can achieve a louder sound, and helps the sound to be distributed more evenly to the surrounding environment.

[0030] The top of the speaker body 1 is provided with a parts slot 11; the parts slot 11 can be used to place the speaker's power cord, audio cord or control cord, etc.

[0031] When in use, after the speaker emits sound, the sound flows out from the diffuser 4. The second channel column 9, the first channel column 8, and the flow port 6 together form a sound flow channel. At the same time, the echo tube 7 can capture and reflect some of the sound into the sound flow channel. After the sound leaves the flow port, it enters the amplifier tube 5 to amplify the volume. The echo ramp, in conjunction with the amplifier tube 5, can improve the efficiency of sound utilization, achieve a louder sound, and help the sound to be distributed more evenly to the surrounding environment.

[0032] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
