Description

Technical Field

[0001] This utility model relates to a marine loudspeaker, specifically a marine loudspeaker with an easily detachable dustproof mesh cover, belonging to the field of audio equipment technology. Background Technology

[0002] Marine horns, as critical external equipment for ship communication, navigation, and warning systems, are constantly exposed to the harsh marine environment. Their operating environment includes not only high salinity and high humidity air, but also large amounts of salt spray, oil, dust, insects, and silt splashed by waves. These pollutants can easily enter the horn through the sound outlet at the front, causing a decline in its acoustic performance, such as a hoarse sound and reduced volume, threatening the reliability of ship communications. To prevent these problems, existing marine horns typically have a dustproof mesh cover installed outside the sound outlet, providing physical isolation from solid pollutants and splashed liquids.

[0003] However, existing marine horns mostly use adhesive or screws to directly fasten the grille to the horn housing. While this method results in a robust structure, it makes the grille virtually impossible to remove. In the harsh marine environment, the dustproof grille itself quickly accumulates dirt, clogging the mesh and severely impacting the horn's sound output efficiency. When cleaning or replacement is needed, maintenance personnel must use specialized tools for tedious disassembly, which may even damage the horn housing or the grille itself, leading to high maintenance costs and low efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a marine horn with an easy-to-disassemble dustproof mesh cover in order to solve the above-mentioned problems. By setting a connecting block on the fixed frame of the mesh cover connection, and fixing it to the horn base through the connecting groove, it is convenient to disassemble and assemble the entire mesh cover. At the same time, a sliding locking block is set on the side of the connecting block to improve the fixing effect of the mesh cover.

[0023] Please see Figures 1-6 As shown, a marine horn with an easily detachable dustproof mesh cover includes a base 1. An installation structure 2 is connected to the end of the base 1. The installation structure 2 includes a fixing frame 201. The fixing frame 201 is provided at the end of the base 1. A mesh cover 202 is fixedly connected to the middle of the fixing frame 201. A connecting block 204 is fixedly connected to the bottom side of the fixing frame 201. A connecting groove 205 is provided on the side of the base 1. The connecting block 204 is slidably connected to the base 1 through the connecting groove 205. A locking block 206 is slidably connected to the inner side of the base 1. The side of the locking block 206 abuts against the end of the connecting block 204. A connecting structure 3 is provided on the inner side of the base 1.

[0024] As a technical optimization of this utility model, the connecting block 204 has an "L" shaped structure. Multiple connecting blocks 204 are arranged in a ring at equal intervals on the side of the fixing frame 201. Multiple locking blocks 206 are provided on the inner side of the base 1 corresponding to the multiple connecting blocks 204. A first spring 207 is fixedly connected between the bottom side of the locking block 206 and the base 1. A pushing groove 208 is opened on the side of the locking block 206, with one side of the pushing groove 208 having a sloping structure. Multiple release blocks 209 are slidably connected to the inner side of the base 1. The sides of the release blocks 209 are slidably connected to the locking blocks 206 through the pushing groove 208. A control ring 203 is rotatably connected to the side of the base 1. Multiple release blocks 209 are all fixedly connected to the inner side of the control ring 203. A second spring 210 is fixedly connected between the side of the release blocks 209 and the base 1. This design aims to improve the fixing firmness of the mesh cover 202 and facilitate the control of the locking blocks 206. For the locking state of the connecting block 204, a control ring 203 is located on the side of the base 1. Multiple release blocks 209 are fixed inside the control ring 203. After the initial installation of the mesh cover 202 is completed, the user can rotate the control ring 203. Combined with the push of the second spring 210, the side of the release block 209 will slide through the inclined part of the push groove 208 to the middle of the locking block 206. At the same time, as the release block 209 slides, it will drive the locking block 206 to move to the top and lock the position of the connecting block 204, thus completing the installation of the mesh cover 202. When disassembly is required, the control ring 203 needs to be rotated in the opposite direction. At this time, the release block 209 will disengage from the push groove 208, and the locking block 206 will retract under the traction of the first spring 207. Then, the fixing frame 201 and the mesh cover 202 can be removed by rotation, which is convenient for maintenance and cleaning of the marine horn.

[0025] As a technical optimization of this utility model, the installation structure 2 includes a winding rod 302. The winding rod 302 is rotatably connected to the inner side of the base 1. A connecting rope 301 is fixedly connected between the winding rod 302 and the fixing frame 201. The connecting rope 301 is wound around the middle of the winding rod 302. Torsion springs 303 are fixedly connected to the base 1 at both ends of the winding rod 302. A fixing block 305 is provided on the side of the winding rod 302. The fixing block 305 is slidably connected to the base 1. A third spring 306 is fixedly connected between the fixing block 305 and the base 1. A ratchet groove 304 is provided on the side of the winding rod 302. A toothed structure is provided on the side of the fixing block 305. The fixing block 305 engages with the ratchet groove 304 on the winding rod 302 through the toothed structure. When temporarily cleaning the marine horn... To prevent the removed mesh cover 202 from falling off, a connecting rope 301 is connected between the control ring 203 and the retracting rod 302 on the inner side of the base 1. This ensures that the mesh cover 202 remains connected to the base 1 without interfering with the cleaning of the horn. A torsion spring 303 connects the retracting rod 302 to the base 1. Simultaneously, the ratchet grooves 304 on both sides of the retracting rod 302 engage with the teeth on the fixing block 305 on the side, allowing the user to freely pull the connecting rope 301 to extend it to a suitable length for easy maintenance of the marine horn. After cleaning, the user can pull the fixing block 305 to disengage it from the ratchet grooves 304. At this point, the retracting rod 302 can retract the extended connecting rope 301 under the action of the torsion spring 303 for convenient use.

[0026] In use, the main components of the speaker, such as the cone and voice coil, are first installed inside the base 1. A fixing frame 201 is provided at the end of the base 1, and the grille 202 is fixed inside the fixing frame 201, effectively isolating external impurities. When the grille 202 needs to be disassembled for speaker maintenance and cleaning, multiple "L"-shaped connecting blocks 204 are located on the side of the fixing frame 201. When the connecting blocks 204 slide into the connecting grooves 205 on the base 1, the fixing frame 201 is initially fixed, preventing it and the grille 202 from detaching. Multiple locking blocks 206 slide inside the base 1. When the connecting blocks 204 are inserted into the connecting grooves 205, the locking blocks 206 are locked in place. The connecting block 204 pushes the locking block 206 to the bottom. When the connecting block 204 slides to the inside of the connecting groove 205, the locking block 206 can slide to the top to lock the position of the connecting block 204. Thus, by controlling the sliding of the locking block 206, the mesh cover 202 can be quickly disassembled and installed. To improve the fixing firmness of the mesh cover 202 and facilitate the control of the locking state of the locking block 206 on the connecting block 204, a control ring 203 is rotatably located on the side of the base 1. Multiple release blocks 209 are fixed to the inside of the control ring 203.

For disassembly, the control ring 203 is rotated in the opposite direction. The release block 209 disengages from the push groove 208, and the locking block 206 retracts under the traction of the first spring 207. The fixing frame 201 and the mesh cover 202 can then be removed by rotation for easy maintenance and cleaning of the marine horn. During temporary cleaning of the marine horn, to prevent the removed mesh cover 202 from falling off, the control ring 203 and the base are... A connecting rope 301 is connected between the inner retracting rods 302, which allows the net cover 202 to always be connected to the base 1 without interfering with the cleaning of the horn. A torsion spring 303 is connected between the retracting rods 302 and the base 1. At the same time, the ratchet grooves 304 on both sides of the retracting rods 302 engage with the toothed blocks on the side fixing blocks 305, allowing the user to freely pull the connecting rope 301 to extend it to a suitable length for easy maintenance of the marine horn. After cleaning, the user can pull the fixing block 305 to release the engagement between it and the ratchet groove 304. At this time, the retracting rods 302 can retract the extended connecting rope 301 under the action of the torsion spring 303 for convenient use.
