Description

Technical Field

[0001] This utility model relates to a Bluetooth speaker, and more particularly to a split-type magnetic splicing extended Bluetooth speaker. Background Technology

[0002] The design concept of the split magnetic splicing Bluetooth speaker breaks through the limitations of traditional Bluetooth speakers in terms of sound effects and sound coverage area, providing users with a highly flexible and customizable audio solution. This innovative design allows users to freely combine multiple speaker units according to their actual needs, which can not only significantly enhance the sound quality, but also effectively expand the sound coverage area.

[0003] To achieve efficient connection and collaborative operation between speaker units, each speaker unit is equipped with directly exposed electrical contacts. These contacts are responsible for power transmission and data communication between adjacent speaker units. However, exposed electrical contacts are susceptible to moisture, dust, and other contaminants, which can lead to poor contact or short circuits. Furthermore, electrical contacts exposed to air for extended periods may oxidize, increasing resistance, further reducing transmission efficiency, and potentially shortening the lifespan of the entire device.

[0004] Therefore, a split-type magnetic splicing extended Bluetooth speaker needs to be designed. Utility Model Content

[0005] In order to overcome the shortcomings of existing magnetic splicing Bluetooth speakers where the electrical contacts are exposed to the external environment, this utility model provides a split magnetic splicing extended Bluetooth speaker.

[0006] A split-type magnetically connected Bluetooth speaker includes two Bluetooth speakers, a speaker unit, a shock-absorbing mechanism, a guide block, a touch button, an electromagnet, a two-way electric telescopic rod, a baffle, electrical contacts, a connecting frame, and an electric push rod. Each Bluetooth speaker contains a speaker unit with a shock-absorbing mechanism. One Bluetooth speaker has a trapezoidal guide block fixed to its rear side, while the other Bluetooth speaker has a guide groove on its front side. The guide block slides into the guide groove, and touch buttons are located at the interface between the guide block and the guide groove. Both sides of the connecting surface of the two Bluetooth speakers have... Similarly, with an electromagnet, two Bluetooth speakers have bidirectional motorized telescopic rods installed on both the left and right sides inside. Each bidirectional motorized telescopic rod has a baffle fixed to its upper and lower telescopic ends. The left, right, front, and rear sides of both Bluetooth speakers have sliding electrical contacts. Each electrical contact is located directly in front of the baffle on the same side. The four electrical contacts in a single Bluetooth speaker are connected to each other through a connecting frame, which is also slidably connected to the Bluetooth speaker. Each Bluetooth speaker has a motorized push rod installed inside, and the output end of the motorized push rod is connected to the connecting frame. The touch button, electromagnet, bidirectional motorized telescopic rod, electrical contacts, and motorized push rod are all electrically connected.

[0007] Furthermore, the damping mechanism includes rubber gaskets, dampers, and damping springs. Each speaker unit is fitted with a rubber gasket, and multiple dampers are installed between the speaker unit and the inside of the Bluetooth speaker along the circumference. Each damper is connected to a damping spring, and the damping springs are all wrapped around the dampers on the same side.

[0008] Furthermore, it also includes snap-fit ​​components, elastic components, and clamping components. Snap-fit ​​components are slidably connected to both sides of one Bluetooth speaker, and elastic components are connected between the snap-fit ​​components and the Bluetooth speaker on the same side. Clamping components are fixedly connected to both sides of the other Bluetooth speaker. The snap-fit ​​components are arrow-shaped, and the clamping components are V-shaped. The clamping components have a certain degree of elasticity on their upper and lower sides. The V-shaped opening of the clamping component is flush with the arrow of the snap-fit ​​component, and the snap-fit ​​components are snapped into place with the clamping components.

[0009] Furthermore, corner protectors are included; both Bluetooth speakers have corner protectors on their corners.

[0010] Furthermore, it also includes a dustproof mesh, with a dustproof mesh installed on the front side of each speaker unit.

[0011] Furthermore, each electrical contact is coated with an anti-oxidation coating.

[0012] Beneficial effects:

[0013] 1. This utility model covers the electrical contacts with an electric telescopic rod and a baffle to protect them from the influence of the external environment, ensuring good contact between the electrical contacts. At the same time, the anti-oxidation coating on the surface of the electrical contacts can effectively prevent the metal surface from oxidizing, extend the service life of the electrical contacts, and maintain a stable electrical connection.

[0014] 2. This utility model, through the cooperation of the snap-fit ​​and the clamping parts, not only enhances the physical connection strength, but also helps to maintain the relative stability between the two Bluetooth speakers, avoiding the loosening or detachment of electrical contacts caused by external vibration or movement. At the same time, the dustproof net also prevents dust from entering the front of the speaker unit, keeping the whole clean and indirectly maintaining the working environment of the electrical contacts.

Detailed Implementation

[0021] 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.

[0022] Example: A split-type magnetic splicing extended Bluetooth speaker, such as... Figures 1-5As shown, the device includes a Bluetooth speaker 1, a speaker unit 101, a shock-absorbing mechanism, a guide block 2, a touch button 3, an electromagnet 4, a two-way electric telescopic rod 5, a baffle 6, electrical contacts 7, a connecting frame 8, and an electric push rod 9. There are two Bluetooth speakers 1, arranged front and back. Each Bluetooth speaker 1 contains a speaker unit 101, and each speaker unit 101 has a shock-absorbing mechanism. A trapezoidal guide block 2 is fixed to the rear of the front Bluetooth speaker 1, while a guide groove is provided on the front of the rear Bluetooth speaker 1. The guide block 2 slides into the guide groove. A touch button 3 is provided at the interface between the guide block 2 and the guide groove. Electromagnets 4 are provided on both sides of the joint surface of the two Bluetooth speakers 1. Similarly, two-way electric telescopic rods are installed on both sides inside the two Bluetooth speakers 1. Each bidirectional electric telescopic rod 5 has a baffle 6 fixedly connected to its upper and lower telescopic ends. The two Bluetooth speakers 1 have sliding electrical contacts 7 on their left, right, front, and rear sides. Each electrical contact 7 is coated with an anti-oxidation coating to enhance its durability and reliability and reduce the risk of corrosion caused by long-term use or environmental factors. Each electrical contact 7 is located directly in front of the baffle 6 on the same side. The four electrical contacts 7 in a single Bluetooth speaker 1 are connected by a connecting frame 8, which is also slidably connected to the Bluetooth speaker 1. Each Bluetooth speaker 1 has an electric push rod 9 installed inside, and the output end of the electric push rod 9 is connected to the connecting frame 8. The touch button 3, electromagnet 4, bidirectional electric telescopic rod 5, electrical contacts 7, and electric push rod 9 are all electrically connected.

[0023] When two Bluetooth speakers 1 need to be joined, the operator first aligns the trapezoidal guide block 2 on one Bluetooth speaker 1 with the guide groove on the other Bluetooth speaker 1 and slides it until they are fully joined. During this process, the touch button 3 at the joint of the guide block 2 and the guide groove is triggered, thereby activating the built-in electromagnet 4. Once activated, the electromagnet 4 generates a strong magnetic attraction between the two speakers, making them firmly joined together to form a whole. At the same time, after the touch button 3 is triggered, the bidirectional electric telescopic rods 5 inside the two speakers will also drive the baffles 6 on both sides to move closer together. At this time, the baffles 6 no longer block the electrical contacts 7, and the four electrical contacts 7 connected by the connecting bracket 8 on the front and rear sides will contact each other under the drive of the electric push rod 9. The mutual pushing force applied by the electric push rod 9 can effectively ensure that the electrical contacts 7 are in a good contact state. Meanwhile, the baffles 6 can protect the electrical contacts 7 from the influence of the external environment during the time when they are not being joined.

[0024] like Figure 5As shown, the damping mechanism includes rubber gaskets 13, dampers 14, and damping springs 15. Rubber gaskets 13 are fitted onto each speaker unit 101. Multiple dampers 14 are installed circumferentially between the speaker unit 101 and the interior of the Bluetooth speaker 1. Each damper 14 is connected to a damping spring 15, and the damping springs 15 all surround the dampers 14 on the same side. The damping mechanism is mainly used to absorb vibrations generated when the speaker unit 101 plays music or any sound, improving sound quality. It also helps reduce external impacts and indirectly solves the problem of poor contact of the electrical contacts 7 caused by internal vibrations.

[0025] like Figure 1 and Figure 3 As shown, it also includes a snap-fit ​​component 10, an elastic component 11, and a clamping component 12. The snap-fit ​​component 10 is slidably connected to both the left and right sides of the rear Bluetooth speaker 1, and an elastic component 11 is connected between the snap-fit ​​component 10 and the Bluetooth speaker 1 on the same side. The elastic component 11 is a spring. The clamping component 12 is fixedly connected to both the left and right sides of the front Bluetooth speaker 1. The snap-fit ​​component 10 is arrow-shaped, and the clamping component 12 is V-shaped. The upper and lower sides of the clamping component 12 have a certain elasticity. The V-shaped opening of the clamping component 12 is flush with the arrow of the snap-fit ​​component 10. The snap-fit ​​component 10 is snapped into the clamping component 12. Once the Bluetooth speaker 1 is assembled, the operator can manually push the snap-fit ​​10 forward and snap it into the clamp 12. During this process, the elastic element 11 is compressed, and the snap-fit ​​10 will gradually squeeze the clamp 12 to deform it. This cooperation not only enhances the physical connection strength, but also helps to maintain the relative stability between the two Bluetooth speakers, preventing the electrical contacts 7 from loosening or detaching due to external vibration or movement.

[0026] like Figure 1 and Figure 2 As shown, it also includes corner protectors 16. Both Bluetooth speakers 1 have corner protectors 16 on their corners. The corner protectors 16 provide additional physical protection for the device to prevent damage from accidental collisions.

[0027] like Figure 1 As shown, it also includes a dustproof mesh 17. The front side of the speaker unit 101 is provided with a dustproof mesh 17. The dustproof mesh 17 can effectively prevent dust from entering the interior, keep it clean, and extend its service life.

[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
