Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, specifically to a vehicle loudspeaker that is easy to maintain. Background Technology

[0002] A loudspeaker is a transducer that converts electrical signals into sound signals. In today's rapidly developing automotive industry, car loudspeakers are the core component of car audio systems.

[0003] A search revealed a patent, CN215121090U, which discloses a vehicle speaker mounted on a car door. The speaker includes a mounting frame, a connecting structure, and a vibration damping component. The vibration damping component connects the mounting frame to the door body and includes a sealing pad and a vibration damping washer. The vibration damping washer is located within the sealing pad, and the connecting structure passes through the vibration damping washer to fix the speaker to the door body. The soft material of the vibration damping washer reduces the resonance intensity between the speaker and the door body at certain fixed frequencies, thereby reducing speaker distortion. This benefits the voice noise reduction module's sound processing and solves the problem in existing vehicle speakers where the lack of a buffer structure leads to high resonance between the speaker and the door sheet metal, resulting in low in-vehicle voice recognition rates.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned comparative documents use multiple bolts to fix the speaker to the sheet metal position inside the car. However, in actual operation, after long-term use, the car speaker needs to be disassembled for maintenance or replacement. Car speakers installed with bolts are more troublesome to disassemble, maintain or replace in the later stages, which is not convenient for later maintenance of the car speaker. Therefore, there is an urgent need in the field to improve the car speaker in order to solve the defects of the prior art. Utility Model Content

[0029] 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.

[0030] Please see Figures 1-8 A vehicle speaker that is easy to maintain includes a speaker body 1 installed on a mounting port 3 on a vehicle sheet metal 2. The speaker body 1 has a mounting ring 4 on its side that is adapted to the mounting port 3. It also includes a plurality of mounting bolts 5 that pass through and are threadedly connected to threaded holes 6 on the vehicle sheet metal 2. The mounting ring 4 has a plurality of through holes 7 that are adapted to the threaded holes 6. One end of the mounting bolt 5 has a connecting post 8 that is adapted to the through holes 7. The side of the connecting post 8 has a through opening 9. An elastic frame 10 with elasticity and a figure-eight shape is fixedly installed in the through opening 9. The two ends of the elastic frame 10 extend beyond the side of the connecting post 8 and are adapted to the mounting ring 4.

[0031] Specifically, the speaker body 1 mentioned above is a known technology. Its working principle is mainly based on the electromagnetic drive principle. Sound is generated by the vibration of the diaphragm caused by changes in current. When installing the speaker body 1 on the automotive sheet metal 2 for the first time, several mounting bolts 5 are first connected to the threaded holes 6 through the mounting openings 3 in reverse thread, and the mounting bolts 5 are tightened. When installing the speaker body 1, the through hole 7 on the mounting ring 4 on the side of the speaker body 1 is aligned with the end of the connecting post 8, and the speaker body 1 is pressed towards the automotive sheet metal 2. The through hole 7 on the mounting ring 4 moves along the connecting post 8. When the through hole 7 is in position... When the device is moved to the side of the elastic frame 10, the side of the elastic frame 10 is squeezed, and the two ends of the elastic frame 10 retract into the through hole 9 until the through hole 7 exceeds the end position of the elastic frame 10. Since the elastic frame 10 is elastic, the two ends of the elastic frame 10 return to their original shape. The two ends of the elastic frame 10 are engaged with one side of the mounting ring 4, and the installation of the speaker body 1 is completed. When the speaker body 1 needs to be disassembled, maintained or replaced in the future, press the two ends of several elastic frames 10 in opposite directions at the same time. After the two ends of the elastic frame 10 are in the through hole 9, the speaker body 1 can be taken out, which facilitates the maintenance of the vehicle speaker body 1 in the future.

[0032] As a technical optimization of this utility model, an elastic damping pad 11 is provided between the mounting ring 4 and the automotive sheet metal 2. The elastic damping pad 11 is elastic and has several arc-shaped grooves 20 that are adapted to the mounting bolts 5. Before installing the speaker body 1, the elastic damping pad 11 is installed on one side of the automotive sheet metal 2. The arc-shaped grooves 20 pass through the connecting column 8. The elastic damping pad 11 is elastic, which not only has a damping effect on the speaker body 1 after installation, but also, since both the elastic frame 10 and the elastic damping pad 11 are elastic, they both have a squeezing effect on the mounting ring 4, thereby improving the stability of the speaker body 1 after installation.

[0033] As a technical optimization of this utility model, the speaker body 1 has a shielding ring 12 on its side. The shielding ring 12 is adapted to the mounting ring 4 and completely shields several connecting posts 8. The shielding ring 12 has several elastic plates 16 on its side. The elastic plate 16 has a snap-fit ​​protrusion 17 on one side. The mounting ring 4 has an annular snap-fit ​​groove 18 adapted to the snap-fit ​​protrusion 17 on its side. The elastic plate 16 has a buckle groove 19 on one side.

[0034] Specifically, after the speaker body 1 is installed, the shielding ring 12 is snapped onto the side of the speaker body 1 and the mounting ring 4 to shield several connecting posts 8 and the elastic bracket 10, improving the aesthetics of the speaker body 1 after installation. When installing the shielding ring 12, the shielding ring 12 is placed on the side of the speaker body 1 and the mounting ring 4 towards the automotive sheet metal 2, and the shielding ring 12 is pressed firmly. The elastic plate 16 is deformed by the compression until the snap-fit ​​boss 17 moves and snaps into the position of the annular snap-fit ​​groove 18, thus completing the installation of the shielding ring 12. When it is necessary to remove the shielding ring 12, the finger is held at the position of the snap groove 19, and the elastic plate 16 is pulled away from the speaker body 1, so that the snap-fit ​​boss 17 disengages from the annular snap-fit ​​groove 18, and the shielding ring 12 can be removed, making it easy to install and remove the shielding ring 12.

[0035] As a technical optimization of this utility model, an elastic support piece 13 is provided between the opposite side walls of the elastic frame 10. The elastic support piece 13 is elastic and improves the stability of the elastic frame 10 when it is supported and snapped.

[0036] As a technical optimization of this utility model, one end of the connecting column 8 is fixedly connected to a threaded column 14, and one end of the mounting bolt 5 is provided with a connecting hole 15 that is adapted to the threaded column 14. One end of the connecting column 8 is provided with a polygonal snap-fit ​​block 21. The connecting column 8 is threadedly connected to the connecting hole 15 through the threaded column 14, connecting the connecting column 8 and the mounting bolt 5. The connecting column 8 is locked in place by snapping it into the snap-fit ​​block 21 with a tool, which facilitates the connection and installation between the connecting column 8 and the mounting bolt 5. At the same time, the inner sidewall of the shielding ring 12 is pressed tightly against the end of the connecting column 8, which can prevent the connecting column 8 from becoming loose.

[0037] As a technical optimization of this utility model, a first sealing ring 22 and a second sealing ring 23 are respectively embedded on both sides of the shielding ring 12. The first sealing ring 22 and the second sealing ring 23 are both elastic, which improves the sealing effect after the shielding ring 12 is sleeved on the speaker body 1 and the side of the mounting ring 4. In addition, since the first sealing ring 22 and the second sealing ring 23 are elastic, they also play a role in shock absorption and compression fixation.
