Description

Technical Field

[0001] This utility model relates to the field of speaker grille installation technology, and in particular to a fixing device for installing speaker grilles. Background Technology

[0002] A loudspeaker is a very common electronic device found in all sound-producing electronic and electrical equipment. It's a transducer that converts electrical signals into sound signals and releases them into the surrounding environment, performing important functions such as broadcasting announcements and directing operations. During use, dust in the air easily adheres to the cone or diaphragm of the loudspeaker. Since the cone and diaphragm are crucial sound-producing components, dust or moisture adhering to their surfaces will severely affect the loudspeaker's sound production and sound quality. Therefore, most loudspeakers have a grille. When installing the grille, to ensure stability, it usually needs to be manually pressed into the mounting groove, and then bolts are used to align and tighten each bolt individually. Throughout this process, the hand must remain in a pressing position.

[0003] Chinese utility model patent CN217394837U discloses a fixing device for installing a speaker grille, relating to the field of speaker grille installation technology. The device includes a speaker grille, a fixing frame, and a main body. The outer edge of the speaker grille has a locking hole and a fixing hole. A fixing ring is fixedly connected to the outer surface of the left end of the fixing frame. The outer surface of the fixing ring has a second locking hole and a second fixing hole. Bolts are threaded onto the inner surfaces of the first and second locking holes. A protrusion is fixedly connected to the outer side of the fixing frame. The outer surface of the main body has an installation groove. An overlapping platform and a locking block are provided on the inner wall of the opening of the installation groove. A third fixing hole is located on the outer surface of the main body near the installation groove. Bolts are threaded onto the inner surfaces of the first, second, and third fixing holes. Through the cooperation of these structures, manual pressing and tightening of bolts is not required during speaker grille installation, reducing the labor intensity of workers during assembly-line speaker grille installation and improving installation efficiency.

[0004] Regarding the aforementioned technologies, the inventors believe the following drawbacks exist: To reduce the difficulty for workers installing speaker grilles, the device uses a method where a bolt is screwed through locking hole one and locking hole two to lock the speaker grille to the fixing ring. In actual use, workers typically install multiple speaker grilles at once, requiring bolt one to be tightened each time a grille is secured. This results in a large number of bolts being needed, a lengthy installation time, and a poor user experience. Utility Model Content

[0005] To solve the above problems, this utility model provides a fixing device for installing a speaker grille.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a fixing device for installing a speaker grille, comprising a speaker grille, a fixing ring disposed on the side wall of the speaker grille, a fixing frame connected to the fixing ring, and a main body connected to the fixing frame. Fixing holes are provided on the side walls of both the speaker grille and the fixing ring. An installation groove is provided on the side wall of the fixing ring near the speaker grille. A limiting component for limiting the position of the speaker grille is provided on the fixing ring.

[0007] By adopting the above technical solution, when workers need to install the speaker grille, they simply need to press the grille against the fixing ring. This allows the grille to automatically connect with the fixing ring under the action of the limiting component, reducing the probability of the grille separating from the fixing ring when subjected to external force. Subsequently, workers only need to connect the fixing frame to the main body and rotate the fixing frame to connect them, thus initially stabilizing the grille, fixing ring, fixing frame, and main body. Furthermore, workers only need to pass the fixing bolts through the two fixing holes and connect them to the main body to maintain stability, thereby reducing the difficulty of installing the speaker grille.

[0008] Furthermore, the limiting component includes a connecting piece fixed to the side wall of the speaker grille near the fixing ring and two fixing springs symmetrically fixed to the two opposite inner walls of the mounting groove.

[0009] By adopting the above technical solution, when the staff needs to connect the speaker grille and the fixing ring, the staff only needs to connect the connecting piece and the mounting groove and push the speaker grille to move the connecting piece between the two fixing spring pieces, so that the two fixing spring pieces simultaneously press against the connecting piece, thereby keeping the connecting piece stable, thus reducing the difficulty for the staff to install the fixing bolts later.

[0010] Furthermore, connecting plates are fixed to the side walls of both of the fixing springs away from the speaker grille.

[0011] By adopting the above technical solution, when the connecting piece moves between the two fixed spring pieces, the two connecting plates simultaneously press against the connecting piece, thereby increasing the force required for the connecting piece to separate from the mounting groove, and thus improving the stability of the connecting piece.

[0012] Furthermore, compression springs are fixed to the side walls of the two connecting plates that are far apart from each other, and the ends of the two compression springs that are far apart from each other are respectively fixed to the two inner walls opposite to the mounting groove.

[0013] By adopting the above technical solution, when the connecting plate presses against the connecting piece, the compression spring increases the force between the connecting plate and the connecting piece, thereby increasing the sliding friction between the connecting piece and the connecting plate, and thus improving the tightness of the connection between the connecting plate and the connecting piece.

[0014] Furthermore, the side walls of the speaker grille and the fixing ring that are close to each other are provided with arc-shaped grooves to reduce the difficulty for workers to rotate the speaker grille.

[0015] By adopting the above technical solution, the arc-shaped groove reduces the difficulty for staff to rotate the speaker grille, thereby improving the user experience.

[0016] Furthermore, the connecting piece is a connecting piece made of powder metallurgy friction material.

[0017] By adopting the above technical solutions, powder metallurgy friction materials possess high friction coefficients and high wear resistance, enabling rapid absorption of kinetic energy, fast braking and transmission speeds, low wear, high strength, resistance to high temperature and pressure, good thermal conductivity, stable friction coefficients, resistance to seizing, corrosion resistance, low noise, and long service life. Connecting plates made from powder metallurgy friction materials exhibit high friction coefficients and high wear resistance, thereby improving the stability of the connecting plates and effectively extending their service life.

[0018] Furthermore, sliding rods are fixed on the sidewalls of the two connecting plates that are far apart from each other, and the other ends of the two sliding rods are slidably connected to the two inner walls opposite to the mounting groove.

[0019] By adopting the above technical solution, the probability of the sliding rod shifting position is reduced, thereby improving the user experience for staff.

[0020] Furthermore, silicone sheets are fixed to the side walls of the speaker grille and the fixing ring that are close to each other.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. In this application, when workers need to install the speaker grille, they need to press the grille against the fixing ring. This allows the grille to automatically connect with the fixing ring under the action of the limiting component, thereby reducing the probability of the grille separating from the fixing ring when subjected to external force. Subsequently, workers only need to connect the fixing frame to the main body and rotate the fixing frame to connect the fixing frame to the main body, thus initially stabilizing the grille, fixing ring, fixing frame, and main body. Furthermore, workers only need to pass the fixing bolts through the two fixing holes and connect them to the main body to stabilize the grille, fixing ring, fixing frame, and main body, thereby reducing the difficulty of installing the speaker grille.

[0023] 2. In this application, when the staff needs to connect the speaker grille and the fixing ring, the staff only needs to connect the connecting piece and the mounting groove and push the speaker grille to move the connecting piece between the two fixing spring pieces, so that the two fixing spring pieces simultaneously press against the connecting piece, thereby keeping the connecting piece stable, thus reducing the difficulty for the staff to install the fixing bolts later.

[0024] 3. In this application, when the connecting piece moves between the two fixed spring pieces, the two connecting plates simultaneously press against the connecting piece, thereby increasing the force required for the connecting piece to separate from the mounting groove, and thus improving the stability of the connecting piece.

[0031] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] like Figure 1-5As shown in the figure, this application discloses a fixing device for installing a speaker grille, including a speaker grille 1, a fixing ring 11, a fixing frame 2, a main body 21, a limiting component 4, a connecting plate 5, a compression spring 51, a sliding rod 7, and a silicone sheet 8. The fixing ring 11 is disposed on the side wall of the speaker grille 1, and the fixing frame 2 is connected to the fixing ring 11. The main body 21 is connected to the fixing frame 2, and fixing holes 3 are provided on the side walls of both the speaker grille 1 and the fixing ring 11.

[0033] A mounting groove 31 is provided on the side wall of the fixing ring 11 near the speaker grille 1. A limiting component 4 is provided on the fixing ring 11 to limit the speaker grille 1. The limiting component 4 includes a connecting piece 41 and a fixing spring piece 42. The connecting piece 41 is a rectangular sheet structure and is fixed to the side wall of the speaker grille 1 near the fixing ring 11. The fixing spring piece 42 is a sheet structure with an isosceles trapezoidal cross-section. There are four fixing spring pieces 42, which are symmetrically fixed in pairs to the two inner walls opposite to the two mounting grooves 31.

[0034] When the staff needs to connect the speaker grille 1 and the fixing ring 11, the staff only needs to connect the connecting piece 41 and the mounting groove 31 and push the speaker grille 1 to move the connecting piece 41 between the two fixing spring pieces 42, so that the two fixing spring pieces 42 simultaneously press against the connecting piece 41, thereby keeping the connecting piece 41 stable, thus reducing the difficulty for the staff to install the fixing bolts later.

[0035] The connecting plate 5 is a rectangular sheet structure. Multiple connecting plates 5 are provided and are fixed sequentially on the side wall of multiple fixing spring pieces 42 away from the speaker grille 1. When the connecting piece 41 moves between two fixing spring pieces 42, the two connecting plates 5 simultaneously press against the connecting piece 41, thereby increasing the force required for the connecting piece 41 to separate from the mounting groove 31, and thus improving the stability of the connecting piece 41.

[0036] Multiple compression springs 51 are provided, and one end of each compression spring 51 is fixed to the side wall of a multiple connecting plate 5. The other end of each compression spring 51 is fixed to the inner wall of the mounting groove 31. Each compression spring 51 corresponds to a sliding rod 7 and is sleeved on the sliding rod 7.

[0037] When the connecting plate 5 presses against the connecting piece 41, the compression spring 51 increases the force between the connecting plate 5 and the connecting piece 41, thereby increasing the sliding friction between the connecting piece 41 and the connecting plate 5, and thus improving the tightness of the connection between the connecting plate 5 and the connecting piece 41.

[0038] To improve the user experience for staff, arc-shaped grooves 6 are provided on the side walls of the speaker grille 1 and the fixing ring 11 that are close to each other, so as to reduce the difficulty for staff to rotate the speaker grille 1.

[0039] To extend the service life of the connecting piece 41, it is made of powder metallurgy friction material. Powder metallurgy friction material possesses a high coefficient of friction and high wear resistance, enabling rapid absorption of kinetic energy, fast braking and transmission speeds, low wear, high strength, resistance to high temperature and pressure, good thermal conductivity, stable coefficient of friction, resistance to seizing, corrosion resistance, low noise, and long service life. The connecting piece 41 made of powder metallurgy friction material exhibits a high coefficient of friction and high wear resistance, thereby improving its stability and effectively extending its service life.

[0040] The sliding rod 7 is a round rod structure. There are four sliding rods 7, which are fixed to the side walls of the four connecting plates 5 in sequence. The other ends of the four sliding rods 7 are slidably connected to the four inner walls of the two mounting slots 31, respectively. The sliding rods 7 reduce the probability of the compression spring 51 shifting position, thereby improving the user experience for the operator.

[0041] The silicone sheet 8 is a sheet-like structure. Two silicone sheets 8 are provided and are respectively fixed to the side walls of the speaker grille 1 and the fixing ring 11 that are close to each other. When the speaker grille 1 and the fixing ring 11 are connected, the two silicone sheets press against each other, thereby attracting each other and increasing the difficulty of separating the speaker grille 1 and the fixing ring 11, thus improving the stability of the speaker grille 1 and the fixing ring 11.

[0042] The working principle of the fixing device for installing the speaker grille 1 in this embodiment is as follows: When the worker needs to install the speaker grille 1, the worker needs to press the speaker grille 1 against the fixing ring 11. This allows the speaker grille 1 to automatically connect with the fixing ring 11 under the action of the limiting component 4, thereby reducing the probability of the speaker grille 1 separating from the fixing ring 11 when subjected to external force. Subsequently, the worker only needs to connect the fixing frame 2 to the main body 21 and rotate the fixing frame 2 to connect the fixing frame 2 to the main body 21, thereby initially stabilizing the speaker grille 1, fixing ring 11, fixing frame 2, and main body 21. Furthermore, the worker only needs to pass the fixing bolt through the two fixing holes 3 and connect it to the main body 21 to stabilize the speaker grille 1, fixing ring 11, fixing frame 2, and main body 21, thereby reducing the difficulty of installing the speaker grille 1.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
