[0020] Optionally, the guide housing is mounted on the output end of the horn body by bolts.
[0021] By adopting the above technical solution, when the angle adjustment plate or the guide housing needs to be repaired and cleaned, the guide housing is disassembled from the output end of the horn body, thereby facilitating repair and cleaning.
[0022] Optionally, a shell cavity is opened inside the guide shell, the angle adjustment plate is hinged and rotatably matched with the inner wall of the shell cavity, and the angle adjustment plate is connected to an arc plate, and the arc plate is closely matched with the inner wall of the shell cavity.
[0023] By adopting the above technical solution, after the angle adjustment plate is rotated, the arc plate is always tightly fitted to the inner wall of the shell cavity, so that dust is not easy to enter the shell cavity.
[0024] In summary, the present application includes at least one of the following beneficial technical effects:
[0025] 1. The treble produced by the sound unit is amplified by the horn body and transmitted from the output end of the horn body. After the treble is transmitted from the horn body, the angle adjustment plate is rotated so that the treble sound waves are reflected by the angle adjustment plate and directed to the desired propagation direction, thereby conveniently adjusting the propagation angle of the horn.
[0026] 2. The two angle adjustment plates are rotated toward or away from each other, thereby adjusting the direction and width of the guide groove. This not only makes it possible to conveniently adjust the propagation direction of the horn body, but also makes the volume of the treble decrease as the width of the guide groove increases and increase as the width of the guide groove decreases.
[0027] 3. When there is no need to rotate the angle adjustment plate, the rotating handle is rotated and stored in the storage groove, so that the rotating handle is not easy to interfere with the reflection and propagation of the treble sound waves, thereby ensuring that the user can easily rotate the angle adjustment plate while ensuring the clarity of the treble.

[0033] The following is combined with Figure 1-4 This application is described in further detail.
[0034] The embodiment of the present application discloses a horn with adjustable sound wave angle. Figure 1 The horn with adjustable sound wave angle comprises a sound generating unit 1, a horn body 2, a guide shell 3 and an angle adjustment plate 4. The generating unit is used for bass, midrange and treble to ensure that the audio is completely restored.
[0035] Reference Figure 1 and Figure 2 The input end of the horn body 2 is fixedly mounted on the sound generating unit, and a horn cavity 201 is provided inside the horn body 2, and the cross section of the horn cavity 201 is prismatic. The horn cavity 201 is arranged through, and one end of the horn cavity 201 with a small inner diameter extends to the location of the sound generating unit 1, and the other end of the horn cavity 201 with a small inner diameter extends to the output end of the horn body 2.
[0036] Reference Figure 3 A horn core 21 is disposed in the horn cavity 201. The horn core 21 is arranged in a spindle shape and is fixedly mounted on the sound unit 1 so that the high-pitched sound waves propagate between the outer peripheral surface of the horn core 21 and the inner wall of the horn cavity 201, thereby ensuring the clarity of the high-pitched sound. In addition, a vibration membrane 22 is fixedly mounted on the output end of the horn body 2 so that the sound waves in the horn cavity 201 are propagated to the outside of the speaker through the vibration membrane 22.
[0037] Reference Figure 2 and Figure 3 , two guide housings 3 and two angle adjustment plates 4 are provided, and the two guide housings 3 and the two angle adjustment plates 4 are arranged one by one. In addition, the two angle adjustment plates 4 are arranged opposite to each other, and a guide groove 5 is provided between the two angle adjustment plates 4, so that the width of the guide groove 5 can be changed by adjusting the distance between the two angle adjustment plates 4, thereby adjusting the propagation angle and volume of the high sound transmitted from the horn cavity 201.
[0038] Specifically, when the treble needs to be propagated in a first direction, the two angle adjustment plates 4 are rotated in the first direction, so that the guide slot 5 faces the first direction, so that the treble is propagated in the first direction; subsequently, when the treble needs to be propagated in a second direction, the two angle adjustment plates 4 are rotated in a direction away from the first direction and close to the second direction, so that the guide slot 5 faces the second direction, so that the treble is propagated in the second direction;
[0039] When the volume of the treble needs to be increased, the two angle adjustment plates 4 are rotated in directions toward each other, thereby reducing the width of the guide groove 5, so that the sound waves of the treble are concentrated in a smaller space, thereby increasing the volume of the treble; when the volume of the treble needs to be reduced, the two angle adjustment plates 4 are rotated in directions away from each other, thereby increasing the width of the guide groove 5, thereby concentrating the sound waves of the treble in a larger space, thereby reducing the volume of the treble.
[0040] Reference Figure 2 and Figure 3 The guide housing 3 is installed at the output end of the horn body 2 by bolts, and a housing cavity 301 is provided inside the guide housing 3. The angle adjustment plate 4 is hinged and rotated to fit the inner wall of the housing cavity 301, and the cross section of the angle adjustment plate 4 is arranged in an arc shape, and the arc surface of the angle adjustment plate 4 is arranged toward the guide groove 5, so that the specific opening curvature of the angle adjustment plate 4 can be adjusted, and then the frequency response, diffusion waveform and diffusion angle of the treble can be adjusted, so as to ensure the auditory experience of the audience.
[0041] Reference Figure 4 The angle adjustment plate 4 is integrally connected with an arc plate 41, and the arc plate 41 is closely matched with the inner wall of the shell cavity 301, so that when the angle adjustment plate 4 rotates, the shell cavity 301 remains closed, thereby preventing dust from entering the shell cavity 301.
[0042] Reference Figure 3 and Figure 4 The angle adjustment plate 4 is provided with a grip receiving groove 401, which is located on the side of the angle adjustment plate 4 close to the guide groove 5. A rotating grip 42 is provided in the grip receiving groove 401, and one end of the rotating grip 42 is rotatably matched with the inner wall of the grip receiving groove 401, so that the user can rotate the angle adjustment plate 4 by rotating the grip 42, thereby reducing the occurrence of the situation where the angle adjustment plate 4 is difficult to turn out from the guide housing 3 and rotate.
[0043] Reference Figure 3 and Figure 4 The surface of the rotating handle 42 is flush with the surface of the angle adjustment plate 4, so that when there is no need to rotate the angle adjustment plate 4, the rotating handle 42 is rotated and stored in the handle storage groove 401, so that the rotating handle 42 is not easy to interfere with the reflection and propagation of the treble sound waves, thereby ensuring that the user can easily rotate the angle adjustment plate 4 while ensuring the clarity of the treble.
[0044] Reference Figure 4A rotating hole 421 is provided on the surface of the rotating handle 42, and the rotating hole 421 is located at the other end of the rotating handle 42, so that the user can insert a finger into the rotating hole 421 and drive the angle adjustment plate 4 to rotate out of the handle storage groove 401 through the rotating handle 42. The inner wall of the slot of the rotating hole 421 is chamfered so that the user's finger is not easily scratched by the inner wall of the slot of the rotating hole 421.
[0045] The implementation principle of a horn with adjustable sound wave angle in an embodiment of the present application is as follows: the sound unit 1 generates treble, and the treble sound waves are transmitted to the horn cavity 201, so that the treble sound waves are reflected between the outer peripheral surface of the horn inner core 21 and the inner wall of the horn cavity 201 and propagate to the vibration membrane 22, and the vibration membrane 22 causes the air in the guide groove 5 to vibrate, thereby propagating the treble to the outside of the speaker.
[0046] When the propagation angle of the horn needs to be adjusted, press the rotating handle so that the rotating handle flips out from the grip storage groove 401, and then insert the finger into the rotating hole 421 to provide a force point for turning the rotating handle, so as to conveniently and comfortably adjust the propagation angle of the horn with high precision.
[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
