Technical Field

[0001] This utility model relates to the field of loudspeaker technology, and in particular to a loudspeaker that is easy to repair. Background Technology

[0002] A loudspeaker is a very common amplification device and a modern electroacoustic component. Its function is to convert electrical signals into sound. When an audio current is transmitted to the coil, the coil generates a magnetic field that interacts with the magnetic field of the magnet, causing the diaphragm to vibrate. Because the audio current changes at any time, the loudspeaker's coil will move forward or backward, and thus the loudspeaker's cone will move accordingly, causing changes in the density of the air to produce sound.

[0003] When a speaker malfunctions, it needs to be disassembled for repair or replacement. However, modern speakers are generally connected to audio equipment with multiple sets of screws, making installation and disassembly cumbersome and reducing repair efficiency. Furthermore, it is not convenient to remove and replace the speaker cover, causing dust to adhere to the cover and affect sound output, thus impacting the speaker's performance.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0040] Reference Figures 1-4 A servoir-friendly loudspeaker includes a loudspeaker body 1, which contains key components required for sound production, such as magnets, voice coils, and diaphragms. Since loudspeakers are existing technology in this field, detailed descriptions are omitted. An annular retaining strip 2 is mounted on the top surface of the loudspeaker body 1, and a loudspeaker mounting shell 3 is snapped onto the loudspeaker body 1. An annular retaining groove 4 is formed on the inner bottom surface of the loudspeaker mounting shell 3. A dust cover 5 is snapped onto the loudspeaker mounting shell 3 to prevent dust, moisture, and other contaminants from entering the loudspeaker, thereby protecting the loudspeaker components from damage.

[0041] A horn that is easy to maintain also includes a fixing component and a disassembly component. The fixing component is used to fix the horn mounting shell 3 to the horn body 1 for installation, and the disassembly component is used to install and remove the dust cover 5.

[0042] Furthermore, the annular retaining strip 2 and the annular retaining groove 4 are matched in shape and engage with each other. This design ensures that the speaker mounting shell 3 can be stably installed on the speaker body 1, making the connection between the speaker mounting shell 3 and the speaker body 1 more secure and reliable.

[0043] Furthermore, the fixing components include a sleeve 21, a locking block 22, a cavity 23, an inner plate 24, a spring 25, a plug rod 26, and a handle 27. The sleeve 21 is fixed to the speaker body 1, and the locking block 22 is fixed to the sleeve 21. Multiple locking blocks 22 are provided, a design that allows the locking blocks 22 to be evenly distributed around the sleeve 21, providing stable locking points for the mounting bracket 31. The locking blocks 22 are arranged in a circumferential array. The cavity 23 is opened within the locking block 22, and the inner plate 24 is fixed within the cavity 23. The spring 25 is fixed on opposite sides of the inner plate 24, providing elastic support for the plug rod 26, allowing the plug rod 26 to slide under external force and return to its original position after the external force is removed. The plug rod 26 is fixed to the spring 25 and slidably connected to the locking block 22. Two plug rods 26 are provided, and the handle 27 is fixed to the plug rod 26. Using the handle 27, users can easily push the plug 26 to slide, thus installing and removing the fastener.

[0044] Furthermore, the fastener also includes a mounting bracket 31 and a socket 32. The mounting bracket 31 is fixed to the speaker mounting housing 3, and the socket 32 ​​is formed on the mounting bracket 31. The main function of the socket 32 ​​is to receive the plug rod 26, realizing the plug-in connection between the fastener and the mounting bracket 31.

[0045] Furthermore, the outer periphery of the mounting bracket 31 is set to correspond to the shape of the locking block 22, the mounting bracket 31 is engaged with the locking block 22, the insertion rod 26 is on the same horizontal plane as the insertion hole 32, and the insertion rod 26 is inserted into the insertion hole 32.

[0046] Furthermore, the disassembly components include a wedge-shaped groove 301, a recess 51, a compression spring 52, and a wedge-shaped block 53. The wedge-shaped groove 301 is formed on the inner wall of the horn mounting housing 3, and its shape is wedge-shaped, meaning the groove opening is narrow and the bottom is wide. This design helps to achieve a secure engagement with the wedge-shaped block 53. The recess 51 is formed inside the dust cover 5, and multiple wedge-shaped grooves 301 and recesses 51 are arranged in a circumferential array. The recesses 51 are positioned corresponding to the wedge-shaped grooves 301, and their main function is to accommodate the compression spring 52 and the wedge-shaped block 53 and provide them with a sliding track.

[0047] A compression spring 52 is fixed to the inner wall of the groove 51, and a wedge block 53 is fixed to the compression spring 52. The number of blocks corresponds to the number of wedge slots 301. The wedge block 53 slides within the groove 51 and engages with the wedge slot 301. The compression spring 52, fixed to the inner wall of the groove 51, provides elastic support for the wedge block 53. The elastic force of the compression spring 52 allows the wedge block 53 to fit tightly within the wedge slot 301, thus achieving a stable engagement.

[0048] The functional principle of this utility model can be explained through the following operation methods:

[0049] During the installation of the speaker mounting housing 3, the user first secures the fastener bracket 21 to the speaker body 1, then places the mounting bracket 31 on the bracket 21, ensuring that the locking block 22 matches the outer circumference of the mounting bracket 31 and engages. Next, the user slides the insertion rod 26 using the handle 27, inserting it into the insertion hole 32 of the mounting bracket 31. Under the elastic force of the spring 25, the insertion rod 26 is firmly fixed in the insertion hole 32, thus achieving a fixed connection between the speaker mounting housing 3 and the speaker body 1.

[0050] During the disassembly of the speaker mounting housing 3, the user pushes the insert rod 26 in the opposite direction using the handle 27 to slide it out of the insertion hole 32. Then, the user can easily remove the mounting bracket 31 from the sleeve 21, completing the disassembly of the speaker mounting housing 3. This allows the speaker mounting housing 3 to be separated from the speaker body 1, facilitating quick internal inspection of the speaker body 1 by staff, making inspection convenient and improving its efficiency.

[0051] During the installation of the dust cover 5, the dust cover 5 is placed on the speaker mounting housing 3, so that the groove 51 corresponds to the wedge groove 301. Then, the wedge block 53 is pushed into the wedge groove 301 under the elastic force of the compression spring 52, and gradually locks in place due to the wedge-shaped design of the wedge groove 301. As the wedge block 53 slides and locks in place, the dust cover 5 is firmly fixed to the speaker mounting housing 3, allowing the dust cover 5 to be quickly installed on the speaker mounting housing 3 for dust protection, preventing dust and moisture from seeping into the speaker, thereby protecting the speaker components from damage and improving the speaker's performance.

[0052] During the disassembly of the dust cover 5, the user needs to apply a certain external force to overcome the elasticity of the compression spring 52, so that the wedge block 53 slides out of the wedge groove 301. Once the wedge block 53 slides out of the wedge groove 301, the dust cover 5 can be easily removed from the speaker mounting shell 3, so that the dust cover 5 can be disassembled and cleaned to avoid blockage affecting the normal use of the speaker.

[0053] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
