Description

Technical Field

[0001] This invention belongs to the field of speaker technology, specifically relating to a modular dual-body Bluetooth speaker splicing structure. Background Technology

[0002] Currently, the dual-unit Bluetooth speaker splicing structure is widely used in the consumer electronics field. Common designs involve setting interlocking mechanical clips or sliding rails on two independent speaker shells. The two speakers are manually aligned and fixed together along a predetermined splicing direction, forming a combined stereo playback unit. However, in practical use, especially in playback scenarios where mid-to-high frequency vibrations are significant, achieving a perfectly tight fit between the two speakers is difficult. Due to manufacturing tolerances, assembly errors, or slight deformation during use, a small gap often inevitably exists at the connection point after splicing. Sound wave vibrations generated by the internal speakers are transmitted through the shells to the splicing interface, causing relative mechanical vibration or friction between the two speakers at this gap. This irregular vibration is easily amplified in enclosed or semi-enclosed acoustic environments, generating additional friction noise, impact sounds, or resonance noise, significantly affecting the user experience at low volumes or in quiet intervals. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a modular dual-body Bluetooth speaker splicing structure that can effectively suppress noise interference caused by splicing gaps while enabling convenient splicing of two speakers.

[0004] To achieve the above objectives, the present invention provides the following technical solution: This invention discloses a modular dual-body Bluetooth speaker splicing structure, including a first speaker body and a second speaker body. A socket is provided on one side of the first speaker body, extending laterally inwards. A socket is installed within the socket, and a wedge-shaped protrusion is provided on the outer side of the socket, with the thickness of the wedge-shaped protrusion gradually increasing from the outside to the inside. A tongue corresponding to the socket is provided on one side of the second speaker body, with the outer end of the tongue forming a plug tube. A strip-shaped notch is formed on the outer side of the plug tube, and an arc-shaped block is installed within the notch. The inner end of the arc-shaped block is hinged to the plug tube, and a first reset torsion spring is installed between the arc-shaped block and the plug tube. A mounting groove is provided on the inner sidewall of the arc-shaped block, and an elastic support member is installed within the mounting groove. The elastic support member corresponds to the end face of the wedge-shaped protrusion. When the socket of the first speaker body and the tongue of the second speaker body are engaged, the elastic support member provides elastic support force to the wedge-shaped protrusion away from the side where the first speaker body is located.

[0005] Furthermore, the elastic support includes a guide rod, a support spring, and a push block. The guide rod is fixed in the mounting groove and extends along the axial direction of the insert. The push block has a guide hole that slides with the guide rod. The support spring connects the push block and the insert.

[0006] Furthermore, the guide rod is made of an elastic material, which allows it to deflect under the pressure of the wedge-shaped protrusion.

[0007] Furthermore, a magnetic block is fixed on the push block, and the magnetic block is fixed on the side of the push block facing the first speaker body. A guide hole is opened on the magnetic block. An electromagnet is installed on the inside of the first speaker body. The electromagnet is connected to a switch, a power supply and a controller through wires. A stop rod is fixed at the end of the plug. When the plug is fully inserted, the stop rod can act on the switch and disconnect it.

[0008] Furthermore, an arc-shaped groove corresponding to the stop rod is opened on the inner side of the first speaker body, and a first gear is installed on the outer side of the tongue. The first gear meshes with the second gear, and the second gear is rotatably installed in the gear groove opened at the bottom of the second speaker body. A second reset torsion spring is installed between the second gear and the second speaker body, and the opening of the gear groove is formed at the bottom of the second speaker body.

[0009] Furthermore, a first rubber surface is provided on the side of the first speaker body that is on the same side as the jack, and a second rubber surface is provided on the side of the second speaker body that is on the same side as the tongue.

[0010] Furthermore, an elastic support is installed on the inner side of the socket. Multiple elastic supports are arranged along the circumference of the socket. The elastic supports are used to support the tongue in the radial direction. The elastic support includes multiple arc-shaped elastic sheets stacked in sequence. The multiple arc-shaped elastic sheets are fixedly connected by fasteners. The convex surface of the arc-shaped elastic sheets faces the center of the socket.

[0011] Furthermore, a plug is fixed at the center of the plug tongue, a liquid bladder is installed on the surface of the plug, and a center hole corresponding to the plug is opened at the center of the socket. The liquid bladder protrudes from the surface of the plug and contacts the inner wall of the center hole.

[0012] The beneficial effects of this invention are as follows: This invention discloses a modular dual-body Bluetooth speaker splicing structure. When the first speaker body and the second speaker body are spliced ​​together, the jacks of the first speaker body and the tongues of the second speaker body cooperate to achieve rapid splicing. At this time, the elastic support member provides elastic support force on the side away from the first speaker body by a wedge-shaped protrusion, driving the first speaker body and the second speaker body to move closer to each other, thereby reducing the gap between the first speaker body and the second speaker body in the lateral direction after splicing, and effectively suppressing noise interference caused by the splicing gap.

[0015] like Figures 1-6 As shown, the present invention discloses a modular dual-body Bluetooth speaker splicing structure, including a first speaker body 1 and a second speaker body 2. Both the first speaker body 1 and the second speaker body 2 are square structures. A socket 3 is provided on one side of the first speaker body 1. The socket 3 is a circular hole and extends inward along the lateral direction of the first speaker body 1. A socket 4 is installed in the socket 3 and extends along the axial direction of the socket 3. A wedge-shaped protrusion 5 is provided on the outer side of the socket 4, and the thickness of the wedge-shaped protrusion 5 gradually increases from the outside to the inside.

[0016] Specifically, the second speaker body 2 disclosed in this invention has a tongue 6 corresponding to the socket 3 on one side. The outer end of the tongue 6 forms a plug 7, and a strip-shaped notch 8 is formed on the outer side of the plug 7. An arc-shaped block 9 is installed in the notch 8. The outer arc surface of the arc-shaped block 9 corresponds to the outer arc surface of the plug 7, which facilitates insertion. The inner end of the arc-shaped block 9 is hinged to the plug 7. A first return torsion spring 10 is installed between the arc-shaped block 9 and the plug 7, which can be used to restore the arc-shaped block 9 to its original position. An installation groove 11 is opened on the inner side wall of the arc-shaped block 9. An elastic support member 26 is installed in the installation groove 11. The elastic support member 26 corresponds to the end face of the wedge-shaped protrusion 5. When the socket 3 of the first speaker body 1 and the tongue 6 of the second speaker body 2 are engaged, the elastic support member 26 provides elastic support force to the wedge-shaped protrusion 5 away from the side where the first speaker body 1 is located. By using the above method to splice and match the speakers, it is possible to quickly splice the two speakers together. At this time, the elastic support 26 provides elastic support to the wedge-shaped protrusion 5 on the side away from the first speaker body 1, driving the first speaker body 1 and the second speaker body 2 to move closer to each other, thereby reducing the gap between the first speaker body 1 and the second speaker body 2 in the lateral direction after splicing, and effectively suppressing noise interference caused by the splicing gap.

[0017] In this invention, during the insertion of the tongue 6 into the socket 3, the wedge-shaped protrusion 5 gradually presses against the arc-shaped block 9 as the insertion depth increases, causing the arc-shaped block 9 to open outward against the elastic force of the first reset torsion spring 10, facilitating the insertion of the tongue 6. Once the tongue 6 is fully inserted, the continuous thrust of the elastic support 26 effectively eliminates the mating gaps caused by manufacturing tolerances or long-term wear, thus preventing relative wobbling or loosening of the two speaker bodies after assembly. Compared to traditional snap-fit ​​assembly methods, this structure achieves a more reliable and stable mechanical connection while ensuring convenient insertion and removal, making it particularly suitable for dual-speaker applications requiring frequent assembly and disassembly, effectively preventing accidental detachment of the two speakers due to accidental collisions or vibrations during transport.

[0018] In this embodiment, the elastic support 26 includes a guide rod 12, a support spring 13, and a push block 14. The guide rod 12 is fixed in the mounting groove 11 and extends along the axial direction of the insert 7. The push block 14 has a guide hole 15 that slides with the guide rod 12. The support spring 13 connects the push block 14 and the insert 7. This combination structure of the guide rod 12, spring, and push block 14 has good maintainability and replaceability. When the support spring 13 fails due to fatigue after long-term use, it can be easily replaced without replacing the entire arc-shaped block 9 or the insert tongue 6 assembly, reducing later maintenance costs. In addition, the push block 14 and the end face of the wedge-shaped protrusion 5 form a surface contact, which significantly reduces contact stress and wear compared to traditional point contact or line contact.

[0019] In this embodiment, the guide rod 12 is made of elastic material. Under the pressure of the wedge-shaped protrusion 5, the guide rod 12 can deflect, which makes it easier for the push block 14 to cooperate with the end face of the wedge-shaped protrusion 5 after it is inserted into place.

[0020] In this embodiment, a magnetic block 16 is fixed on the push block 14. The magnetic block 16 is fixed on the side of the push block 14 facing the first speaker body 1. A guide hole 15 is correspondingly opened on the magnetic block 16. An electromagnet 17 is also installed on the inner side of the first speaker body 1. The electromagnet 17 is connected to a switch, a power supply, and a controller through wires. A stop rod 18 is fixed to the end of the plug 7. When the plug tongue 6 is fully inserted, the stop rod 18 can act on the switch and disconnect it. During the insertion process, the electromagnet 17 is energized. The magnetic block 16 is attracted by the electromagnet 17, causing it to compress the support spring 13, leaving space for the wedge-shaped protrusion 5. After insertion, the stop rod 18 acts on the switch and disconnects it. At this time, the electromagnet 17 is ineffective, and the support spring 13 supports the push block 14 acting on the wedge-shaped protrusion 5, and the device is used normally. It can be understood that the switch adopts a common contact switch, which contacts the contact point through an elastic lever. When the stop rod 18 contacts the elastic lever, it disconnects the contact point. In some other embodiments, the switch may also be a contact switch, in which the switch is turned off when the abutment 18 contacts it. The above-mentioned contact method is prior art and will not be described in detail here.

[0021] In this embodiment, an arc-shaped groove 19 corresponding to the abutment 18 is provided on the inner side of the first speaker body 1. A first gear 20 is installed on the outer side of the tongue 6. The first gear 20 meshes with a second gear 21. The second gear 21 is rotatably installed in a gear groove 22 opened at the bottom of the second speaker body 2. A second return torsion spring 23 is installed between the second gear 21 and the second speaker body 2. The opening of the gear groove 22 is formed at the bottom of the second speaker body 2. The first speaker body 1 and the second speaker body 2 can be easily separated by the above method. In actual use, the second gear 21 is manually rotated, which drives the first gear 20 and the tongue 6 to rotate, so that the push block 14 is misaligned with the wedge-shaped protrusion 5 in the circumferential direction. After misalignment, it is convenient to separate the first speaker body 1 and the second speaker body 2, which is convenient to use.

[0022] In this embodiment, a first rubber surface 24 is provided on the side of the first speaker body 1 that is on the same side as the jack 3, and a second rubber surface 25 is provided on the side of the second speaker body 2 that is on the same side as the tongue 6. The first rubber surface 24 and the second rubber surface 25 are closely fitted together, which reduces the friction and vibration between the two during use and plays a damping role.

[0023] In this embodiment, an elastic support 26 is installed on the inner side of the socket 3. Multiple elastic supports 26 are arranged circumferentially along the socket 3. The elastic supports 26 are used to support the tongue 6 radially. The elastic support 26 includes multiple arc-shaped elastic sheets 27 stacked sequentially. The multiple arc-shaped elastic sheets 27 are fixedly connected by fasteners 28. The convex surface of the arc-shaped elastic sheets 27 faces the center of the socket 3, which plays a locking role. At the same time, the combination of multiple elastic supports 26 can ensure that the coaxiality between the tongue 6 and the socket 3 reaches the optimal state.

[0024] In this embodiment, a core 29 is fixed at the center of the tongue 6, and a liquid bladder 30 is installed on the surface of the core 29. A central hole 31 corresponding to the core 29 is opened at the center of the socket 4. The liquid bladder 30 protrudes from the surface of the core 29 and contacts the inner wall of the central hole 31, thereby playing a role in vibration damping.
