Description

Technical Field

[0001] The utility model relates to a hanging bell sound box. Background Art

[0002] Suspended speakers are installed by hanging, mostly indoors, such as in restaurants or bars, and can be installed with hanging lamps. Currently, most suspended speakers on the market use their input wires as the load-bearing wires for suspension. This structure, especially for some heavier suspended speaker products, has the following problems: 1. The wires are overloaded and there is a risk of breaking due to pulling, which in turn brings the risk of leakage; 2. The wires are always in a straight state, and the straight ends of the wires need to be knotted to form a limit point. After being stretched for a long time, the knots are too tight and difficult to untie, which is not only not conducive to the overall disassembly and maintenance of the speaker, but also inconvenient when adjusting the height of the speaker later. At the same time, after the height of the speaker is lowered, the original knot is exposed, and it is deformed due to the long-term knotting, forming an unpleasant distorted appearance. In addition, more and more places are now using suspended speakers, and of course there are also some stages, dance floors or restaurants that combine fog effects, and even outdoors. The air humidity in these places is high, and the water condensed on the top of the venue may come to the top of the speaker along the load-bearing line, causing the top of the speaker to be damp and the mounting screw rods on the top of the speaker to rust, making the speaker difficult to disassemble and maintain later. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a hanging bell sound box, which comprises a main body, a top cover and a hook.

[0004] The main body includes a housing and electronic components mounted within the housing. The housing is generally bell-shaped, with a mounting slot located in the center of the top. The bottom of the mounting slot has a coaxial opening. The mounting slot has assembly screw holes surrounding the opening, and the bottom of the assembly screw holes is sealed.

[0005] The shape of the top cover is consistent with that of the mounting groove, and is embedded in the mounting groove. The top cover is provided with countersunk holes corresponding to the assembly screw holes one by one, and a sealing ring coaxial with the middle through hole is provided in the step groove of the countersunk hole. The cross section of the sealing ring is triangular, that is, the top is pointed and can be ground and flattened. The top cover is fixed to the shell by the assembly screw passing through the countersunk hole and screwed into the assembly screw hole. The bottom end of the head of the assembly screw flattens the top of the sealing ring, and the assembly screw hole forms a sealed space, thereby forming a sealed protection for the screw part of the assembly screw, making it less likely to rust and convenient for later maintenance and disassembly. In addition, the edge of the top cover extends downward to form a pressing ring, and the edge of the mounting groove is provided with an annular sealing gasket. The pressing ring presses the sealing gasket, so that the top of the speaker forms a higher sealing state, which can prevent water dripping to the top of the speaker from entering the interior of the speaker and causing short circuit problems in electronic components.

[0006] A hanging bracket is provided in the middle of the top cover, a hanging hole is provided on the top of the hanging bracket, the hook is locked in the hanging hole and is bound by a steel rope, so that the entire speaker is suspended and installed through the steel rope.

[0007] The present invention provides a hanging bell speaker, which is a type of suspended speaker. To prevent water dripping from the top of the speaker from causing the screws of the assembly screws that secure the top cover to become damp and rusty, a protruding sealing ring is provided in the countersunk hole on the top cover for the assembly screws to be inserted. The cross-section of the sealing ring is triangular, i.e., the top is pointed. When the assembly screw is tightened, the bottom of the head of the assembly screw is rotated and pressed downward to flatten and press against the sealing ring, thereby placing the entire assembly screw in a sealed space, avoiding contact with water vapor and thus not easily rusting. Even after long-term use, even after use outdoors or in a humid environment, it is not easy to rust. When the speaker needs to be disassembled for maintenance, the assembly screws can be removed smoothly without affecting disassembly and assembly. In addition, the present invention also provides an annular sealing gasket between the main body and the top cover, which can further improve the sealing of the top of the speaker and prevent water dripping from the top of the speaker from entering the interior of the speaker and causing short circuits in electronic components.

[0008] Preferably, the back of the top cover is provided with an interface for connecting the speaker to a power source. The interface is covered with a sealing silicone plug, and the silicone plug is provided with a wire outlet, so that the silicone plug forms a seal on the interface to prevent water from entering.

[0009] Preferably, a panel is provided at the bottom of the shell, and an aluminum mesh is provided on the downward side of the panel.

[0010] Preferably, an annular gap is provided on the edge of the downward-facing side of the panel, and the edge of the aluminum mesh is bent upward to form a fixing ring, which is inserted into the annular gap of the panel. Screws are provided on the periphery of the panel to connect to the annular gap, and screws are screwed in to tighten the aluminum mesh, thereby improving the installation security of the aluminum mesh and preventing it from falling.

[0011] Preferably, a woofer and a tweeter are provided in the main body, and in order to improve the sound quality of the speaker, the woofer and the tweeter are coaxially arranged, and a center column is placed on the T-iron of the woofer and the tweeter is installed.

[0012] Preferably, a nut is embedded in the center column, and a stud passes through the T-iron of the woofer and is screwed into the nut of the center column to secure the T-iron and the center column. This allows the stud's length to be precisely defined, and its excess portion can be accommodated within the T-iron. The center column is provided with a boss at the end, and a protruding retaining ring is provided on the outer periphery of the boss. The tweeter's U-iron end is provided with a docking groove, and the peripheral wall of the docking groove is provided with an annular retaining groove. The boss of the center column is inserted into the docking groove of the U-iron and is secured by the retaining ring and the annular retaining groove. The mounting structure is simple, firm, and easy to form.

[0013] Preferably, the tweeter's sound diaphragm is provided with a hemispherical protrusion in the middle, and a ring-mounted protrusion is provided on the outer periphery of the hemispherical protrusion. The sound diaphragm is pressed and installed by a pressure ring, and the pressure ring presses the outer half circle of the ring-mounted protrusion, so that the ring-mounted protrusion and the hemispherical protrusion in the middle have a consistent phase, thereby improving the sound quality.

[0014] Preferably, after the voice coils of the woofer and tweeter are wound, the ends are wrapped around the external wire, and the joint parts of the voice coil and the external wire are welded together on a copper foil, which can greatly improve the connection strength between the voice coil wire and the external wire.

[0015] Preferably, the drum paper of the woofer adopts a PP basin, which has high waterproof performance, UV resistance and aging resistance, and the edge of the drum paper is provided with a convex ring. The convex ring adopts a structure with a thick middle and gradually thinner inner and outer circles, so that the unit moves evenly during vibration, the upper and lower vibrations are more symmetrical, and the sound quality is good.

[0016] Preferably, in order to ensure the fullness of the low frequency and sufficient mid-frequency, the voice coil of the woofer adopts a double-wire parallel winding method, and the two wire ends of the double wire are welded together at the end. When the cross-sectional area is the same as that of a single wire, the surface area of ​​the double wire is larger, and the effective resistance to higher frequency current is reduced. Therefore, when the number of coils and the width are the same, the coil thickness and weight of the double-wire parallel winding structure are reduced, thereby reducing the weight of the voice coil and the vibration system, improving the sensitivity of the voice coil, avoiding the shortcomings of the traditional two-layer coil winding method of protruding mid-frequency but insufficient low-frequency, and avoiding the problem of the four-layer coil winding method of guaranteed low frequency but weakened mid-frequency.

[0017] From the above description of the utility model, it can be seen that the utility model has the following beneficial effects:

DETAILED DESCRIPTION

[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clear and understandable, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] See also Figures 1 to 11 , a hanging bell speaker includes a main body 1, a top cover 2 and a hook 3.

[0038] The main body 1 includes a housing and electronic components mounted therein. The housing is generally bell-shaped, with a mounting slot 11 defined in the center of the top. A coaxial opening is defined at the bottom of the mounting slot 11. An assembly screw hole 12 is defined within the mounting slot 11, surrounding the opening. The bottom of the assembly screw hole 12 is sealed.

[0039] In one embodiment, the bottom of the housing is provided with a panel 13, and an aluminum mesh 14 is provided on the downward-facing side of the panel 13. Preferably, an annular gap is defined on the downward-facing edge of the panel 13, and the edge of the aluminum mesh 14 is bent upward to form a retaining ring, which is inserted into the annular gap of the panel 13. Screws are provided around the periphery of the panel 13, connecting to the annular gap, and jackscrews 15 are screwed in to secure the aluminum mesh 14, thereby enhancing the secure installation of the aluminum mesh 14 and preventing it from falling.

[0040] The shape of the top cover 2 is consistent with that of the mounting groove 11, and is embedded in the mounting groove 11. The top cover 2 is provided with a countersunk hole 21 that corresponds one-to-one with the assembly screw hole 12, and a sealing ring 22 coaxial with the middle through hole is provided in the step groove of the countersunk hole 21. The cross-section of the sealing ring 22 is triangular, that is, the top is pointed and can be ground and flattened. The top cover 2 is fixed to the housing by the assembly screw passing through the countersunk hole 21 and screwed into the assembly screw hole 12. The bottom end of the head of the assembly screw flattens the top end of the sealing ring 22, and the assembly screw hole 12 forms a sealed space, thereby providing sealing protection for the screw portion of the assembly screw, making it less likely to rust. Later maintenance is convenient for disassembly and assembly, and no additional sealing ring is required, thereby avoiding cost increase. In addition, the edge of the top cover 2 extends downward to form a pressing ring 23. The edge of the mounting groove 11 is provided with an annular sealing gasket 5. The pressing ring 23 compresses the sealing gasket, thereby forming a high seal on the top of the speaker, preventing water dripping onto the top of the speaker from entering the interior of the speaker and causing short circuits in electronic components. In other embodiments, to prevent the annular sealing gasket 5 from deviating from its position, the bottom of the pressing ring 23 is provided with an annular pattern, which can press the annular sealing gasket 5 only at a predetermined position.

[0041] In one embodiment, the back of the top cover 2 is provided with an interface 24 for connecting the speaker to a power source. The interface 24 is covered with a sealing silicone plug 25, which has a wire outlet reserved therefor, thereby forming a seal with the interface 24 to prevent water from entering.

[0042] A hanger 26 is provided in the middle of the top cover 2 , and a hanging hole is provided on the top of the hanger 26 . The hook 3 is locked in the hanging hole and is bound by a steel rope 4 , so that the entire speaker is suspended and installed by the steel rope 4 .

[0043] Based on the above implementation, in one embodiment, a woofer 16 and a tweeter 17 are provided in the main body 1, and in order to improve the sound quality of the speaker, the woofer 16 and the tweeter 17 are coaxially arranged, and a center column 18 is provided on the T iron of the woofer 16 and the tweeter 17 is installed.

[0044] Specifically, a nut is embedded in the center column 18, and a stud passes through the T-iron of the woofer 16 and is screwed into the nut of the center column 18, securing the T-iron and the center column 18. This allows the stud's length to be precisely defined, and its excess portion can be accommodated within the T-iron. The end of the center column 18 is provided with a boss, and the outer periphery of the boss is provided with a protruding retaining ring. The U-iron end of the tweeter 17 is provided with a docking groove, and the peripheral wall of the docking groove is provided with an annular retaining groove. The boss of the center column 18 is inserted into the docking groove of the U-iron and is secured by the retaining ring and the annular retaining groove. The mounting structure is simple, firm, and easy to form.

[0045] As for the speaker, in order to improve the tone, the tweeter 17 has a hemispherical protrusion in the middle of the sound diaphragm, and a ring-mounted protrusion on the outer periphery of the hemispherical protrusion. The sound diaphragm is pressed and installed by a pressure ring, and the pressure ring presses the outer half circle of the protrusion of the ring 23, so that the ring-mounted protrusion and the hemispherical protrusion in the middle have the same phase, thereby improving the sound quality.

[0046] The woofer 16's drum paper utilizes a PP cone, which offers excellent waterproof, UV, and aging resistance. The edge of the drum paper is equipped with a raised ring 162, which is thicker in the middle and gradually thinner in the inner and outer circles. This ensures uniform movement during vibration, more symmetrical upper and lower vibrations, and improved sound quality. Furthermore, to ensure both a full bass and sufficient midrange, the woofer 16's voice coil utilizes a bifilar parallel winding method. This avoids the drawbacks of traditional two-layer winding methods, which produce a prominent midrange but insufficient bass, and the problem of four-layer winding methods, which ensure low frequencies but weaken midrange.

[0047] In addition, after the voice coils of the woofer 16 and the tweeter 17 are wound, the ends are wrapped around the external wires, and the joints between the voice coils and the external wires are welded to a copper foil, which can greatly improve the connection strength between the voice coil wires and the external wires.

[0048] The present invention provides a hanging bell speaker, which is a suspended speaker. To prevent water dripping from the top of the speaker from causing the screws of the assembly screws fixing the top cover 2 to become wet and rust, the top cover 2 has a countersunk hole 21 for the assembly screw to be inserted, which is provided with a protruding sealing ring 22. The cross section of the sealing ring 22 is triangular, that is, the top is pointed. When the assembly screw is tightened, the bottom of the head of the assembly screw is rotated and pressed down to flatten and press against the sealing ring 22, thereby placing the assembly screw as a whole in a sealed space, avoiding contact with water vapor and thus not easily rusting. Even after long-term use, even after use outdoors or in a humid environment, it is not easy to rust. When the speaker needs to be disassembled for maintenance, the assembly screw can be removed smoothly without affecting disassembly and assembly. In addition, the present invention also provides an annular sealing gasket 5 between the main body 1 and the top cover 2, which can further improve the sealing of the top of the speaker and prevent water dripping from the top of the speaker from entering the interior of the speaker and causing short circuits in electronic components.

[0049] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
