[0002] Most directional sound amplification devices on the market are installed outdoors for wide-area announcements, commonly found at school gates and urban / rural squares. However, the metal mesh inside the speaker of these outdoor devices easily accumulates dust during daily use, affecting their amplification effect. Furthermore, the metal mesh on most directional sound amplification devices is fixed, making it difficult to disassemble and clean. To address these issues, we propose technological innovations based on existing directional sound amplification devices. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4A directional sound-enhancing device includes a directional sound-enhancing element 1. A storage box 13 is fixedly installed on the right side of the directional sound-enhancing element 1. A sliding groove is formed through the right side of the directional sound-enhancing element 1, and the sliding groove is connected to the inner cavity of the storage box 13. A set of mounting slots is formed on both the upper and lower sides of the inner side wall of the sliding groove. A spring 15 is fixedly installed in the mounting slot. A set of round-headed pins 16 is fixedly installed on the opposite sides of the two sets of springs 15. A quick-release assembly is installed in the sliding groove and the storage box 13. A rain cover 2 is fixedly installed on the front side of the directional sound-enhancing element 1. A fixing assembly is installed at the bottom of the directional sound-enhancing element 1. The rain cover 2 can protect the sound outlet of the directional sound-enhancing element 1 from rain. The quick-release assembly includes a first mounting frame 11. A second mounting frame 19 is fixedly installed on the right side of the first mounting frame 11. A first mesh cover 14 is placed inside a mounting frame 11, and a second mesh cover 191 is placed inside a second mounting frame 19. A first positioning groove 17 is provided on both the upper and lower sides of the first mounting frame 11, and a second positioning groove 18 is provided on both the upper and lower sides of the second mounting frame 19. A handle 12 is fixedly installed on the left side of the first mounting frame 11. The first mounting frame 11 is slidably positioned within the slide groove of the directional loudspeaker 1, and the second mounting frame 19 is slidably positioned within the storage box 13, corresponding to the slide groove of the directional loudspeaker 1. The outer side of the first mesh cover 14 is located within the slide groove of the directional loudspeaker 1, and the first mesh cover 14 is located in front of the speaker of the directional loudspeaker 1. Pulling the handle 12 to the left will move the first mounting frame 11 and the second mounting frame 19 to the left, thereby moving the first mesh cover 191. The first mesh cover 14 inside the mounting frame 11 moves to the left out of the slide groove of the directional loudspeaker 1. Pushing the first mesh cover 14 forward at this time will push it out of the first mounting frame 11, allowing for thorough cleaning. When the second mounting frame 19 is in place, it will move the second mesh cover 191 to the front of the speaker of the directional loudspeaker 1, ensuring the directional loudspeaker 1 can function normally during the cleaning process of the first mesh cover 14. The handle 12 is located on the left side of the directional loudspeaker 1. The first mounting frame 11 and the second mounting frame 19 have the same dimensions, as do the first mesh cover 14 and the second mesh cover 191. The rounded end of the rounded pin 16 is inserted into the first positioning groove 17 and corresponds to the second positioning groove 18. When the spring 15 drives the rounded pin 16 to insert into the first... When the first mounting frame 11 is inserted into the positioning groove 17, it can be fixed in the slide groove of the directional loudspeaker 1. Similarly, when the round-headed pin 16 is inserted into the second positioning groove 18, it can be fixed in the slide groove of the directional loudspeaker 1. This ensures that the first mesh cover 14 and the second mesh cover 191 can normally provide dustproof and impact protection for the speaker of the directional loudspeaker 1, thereby ensuring the reliability of the device. The fixing component includes an L-shaped support rod 3. A clamp 31 is fixedly installed on the right side of the L-shaped support rod 3. The device can be fixed to the external column by the clamp 31, thereby completing the installation of the device. A tray 32 is fixedly installed on the top of the L-shaped support rod 3. A support base 33 is placed on the top of the tray 32. A connecting seat 34 is rotatably installed inside the support base 33 through a rotating shaft.The connecting seat 34 is fixedly installed at the bottom of the directional loudspeaker 1. A set of first arc grooves are respectively opened through the left and right sides of the connecting seat 34. First bolt holes are evenly opened through the left and right sides of the connecting seat 34, corresponding to the first arc grooves. A second arc groove is evenly opened through the top of the tray 32. A second bolt hole is evenly opened through the bottom of the support seat 33, corresponding to the second arc groove. Bolts are threaded through the first bolt holes of the connecting seat 34 and the first arc grooves of the support seat 33, and screwed onto the nuts. Rotating the connecting seat 34 up and down changes the vertical angle of the directional loudspeaker 1. Tightening the nuts fixes the vertical angle of the directional loudspeaker 1. Similarly, bolts are threaded through the second bolt holes of the support seat 33 and the second arc grooves of the tray 32, and screwed onto the nuts. Rotating the support seat 33 left and right adjusts the horizontal angle of the directional loudspeaker 1. Tightening the nuts fixes the horizontal angle of the directional loudspeaker 1. This allows the directional loudspeaker 1 to achieve strong sound amplification effects at different angles.

[0022] Working principle: The device can be fixed to the external column by clamp 31, thus completing the installation. The rain cover 2 can protect the sound outlet of the directional loudspeaker 1 from rain. Pulling the handle 12 to the left will move the first mounting frame 11 and the second mounting frame 19 to the left, thereby moving the first mesh cover 14 in the first mounting frame 11 out of the slide groove of the directional loudspeaker 1. At this time, pushing the first mesh cover 14 forward will push it out of the first mounting frame 11, thus thoroughly cleaning the first mesh cover 14. When the second mounting frame 19 is in this position, it will move the second mesh cover 191 to the front of the speaker of the directional loudspeaker 1, thus ensuring that the directional loudspeaker 1 can work normally during the cleaning of the first mesh cover 14. When the spring 15 drives the round-headed pin 16 to insert into the first positioning groove 17, the first mounting frame 11 can be fixed in the slide groove of the directional loudspeaker 1. Similarly, when the round-headed pin... Inserting 16 into the second positioning groove 18 will fix the second mounting frame 19 in the slide groove of the directional loudspeaker 1, thus ensuring that the first mesh cover 14 and the second mesh cover 191 can normally provide dustproof and impact protection for the speaker of the directional loudspeaker 1, thereby ensuring the reliability of the device. Using bolts to pass through the first bolt hole of the connecting seat 34 and the first arc groove of the support seat 33, and screwing them into the nut, the vertical angle of the directional loudspeaker 1 can be changed by flipping the connecting seat 34 up and down. Then, tightening the nut will fix the vertical angle of the directional loudspeaker 1. Similarly, using bolts to pass through the second bolt hole of the support seat 33 and the second arc groove of the tray 32, and screwing them into the nut, the horizontal angle of the directional loudspeaker 1 can be adjusted by rotating the support seat 33 left and right. Then, tightening the nut will fix the horizontal angle of the directional loudspeaker 1, thus enabling 1 to achieve a strong sound amplification effect at different angles.
