Description

Technical Field

[0001] This utility model relates to the field of Bluetooth speaker technology, and in particular to a wireless stereo Bluetooth speaker. Background Technology

[0002] A wireless stereo Bluetooth speaker is a portable audio playback device that receives audio signals through Bluetooth wireless communication technology and uses built-in dual-channel or multi-channel sound units to achieve a stereo effect. Its core essence is to break the connection constraints of traditional wired audio devices, complete the reception and high-quality reproduction of audio signals through wireless transmission, and create an immersive stereo listening experience through optimized acoustic structure design.

[0003] While current wireless stereo Bluetooth speakers have made significant progress in portability and sound quality, they still have many shortcomings in structural design and maintenance, with the installation method of the protective mesh being particularly problematic. To protect the internal sound unit from damage caused by dust and foreign objects, a protective mesh is usually installed on the front of the speaker. However, existing products generally use glue to fix the protective mesh to the speaker shell. Although this connection method can achieve initial fixation, its drawbacks become apparent after long-term use. Since the protective mesh is in direct contact with the air, it easily attracts dust, hair, and other debris, and may even breed mold in humid environments. In addition, daily use inevitably involves collisions that can damage the protective mesh, and the strong adhesive makes it difficult to remove. If users forcibly disassemble it, it can easily cause deformation and damage to the protective mesh, and may also damage the surface coating of the speaker shell, and even leave glue residue that is difficult to clean. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a wireless stereo Bluetooth speaker to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a wireless stereo Bluetooth speaker, including a Bluetooth speaker body. The top surface of the Bluetooth speaker body has an upward-facing U-shaped groove. A vertically arranged assembly frame is slidably connected to the inner wall of the U-shaped groove. A protective mesh is fixedly connected inside the assembly frame. Several linear array speakers are embedded in the front of the Bluetooth speaker body, each speaker corresponding to the protective mesh. A horizontally arranged locking frame is fixedly connected to the top of the assembly frame. Two symmetrically arranged control plates are slidably connected inside the locking frame. A spring is fixedly connected between the two control plates. A locking rod is fixedly connected to the side of each control plate away from the spring. Both locking rods penetrate the locking frame and engage with the Bluetooth speaker body.

[0007] Preferably, in any of the above solutions, the inner wall of the U-shaped groove has two symmetrically arranged snap-fit ​​holes, and both snap-fit ​​rods pass through the locking frame and snap-fit ​​with the Bluetooth speaker body through the snap-fit ​​holes.

[0008] Preferably, in any of the above solutions, the inner wall of the U-shaped groove has two symmetrically arranged guide grooves, and guide strips are fixedly connected to both the left and right sides of the assembly frame. The two guide strips are slidably connected to the Bluetooth speaker body through the two guide grooves respectively.

[0009] Preferably, in any of the above solutions, the assembly frame has two corresponding upper and lower reinforcing strips fixedly connected inside, the two reinforcing strips are staggered with several speakers, and the front of the reinforcing strips is fixedly connected to the protective net.

[0010] Preferably, in any of the above solutions, the bottom of the assembly frame is fixedly connected to two clamping plates, both of which are inserted into the inner wall of the U-shaped groove.

[0011] Preferably, in any of the above embodiments, a frame is fixedly connected to the top of the locking frame, a rubber plug is inserted into the inner wall of the frame, and the top surfaces of both control plates are in contact with the bottom surfaces of the rubber plugs.

[0012] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: 1. Enables convenient assembly and disassembly of the protective net, reducing maintenance difficulty and cost. When the protective net accumulates too much dust or becomes damaged and needs repair, first remove the rubber plug inside the frame. Then, press the two control plates to compress the springs and cause the locking rod to disengage from the locking hole on the inner wall of the U-shaped groove. After unlocking, pull the locking frame upwards to slide the assembly frame and protective net upwards along the U-shaped groove. The guide strips on both sides of the assembly frame move smoothly along the guide groove, and the bottom locking plate disengages from the U-shaped groove to complete disassembly. After cleaning or replacing the protective net, align the assembly frame with the U-shaped groove, so that the guide strips are embedded in the guide groove and the locking plate is inserted into the inner wall of the U-shaped groove. Push the locking frame until the locking rod is aligned with the locking hole. The spring returns to its original position, causing the locking rod to insert into the locking hole to lock. Finally, reinstall the rubber plug back into the frame. The entire process requires no tools, avoiding structural damage during disassembly using traditional glue bonding methods, making the maintenance of the protective net more efficient and extending the overall lifespan of the speaker.

[0013] 2. Enhanced protection and sound structure stability ensure high-quality sound output. During assembly, the assembly frame achieves precise positioning through the cooperation of guide strips and guide grooves. The insertion of the bottom plate and U-shaped groove, and the snapping of the locking rod and locking hole form multiple fixation mechanisms, ensuring that the assembly frame and protective netting are firmly attached to the Bluetooth speaker body, preventing displacement due to vibration during use. The reinforcing strips inside the assembly frame are fixedly connected to the protective netting, enhancing its impact resistance and ensuring that its staggered arrangement with the speaker does not obstruct sound transmission. The rubber plugs are attached to the top surface of the control board, preventing dust from entering the locking frame and affecting the operation of the control board and springs, while also limiting the movement of the control board. The coordinated action of all components ensures that the protective netting stably protects the speaker, while also guaranteeing the stability and integrity of the speaker's sound output, thus enhancing the listening experience.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0017] like Figures 1 to 5As shown, a wireless stereo Bluetooth speaker includes a Bluetooth speaker body 1. The top surface of the Bluetooth speaker body 1 has an upward-facing U-shaped groove 2. A vertically arranged assembly frame 3 is slidably connected to the inner wall of the U-shaped groove 2. A protective net 4 is fixedly connected inside the assembly frame 3. Several linear array speakers 5 are embedded in the front of the Bluetooth speaker body 1, and each speaker 5 corresponds to the protective net 4. A horizontally arranged locking frame 6 is fixedly connected to the top of the assembly frame 3. Two symmetrically arranged control plates 7 are slidably connected inside the locking frame 6. A spring 8 is fixedly connected between the two control plates 7. A latching rod 9 is fixedly connected to the side of each control plate 7 away from the spring 8. Both latching rods 9 pass through the locking frame 6 and latch onto the Bluetooth speaker body 1.

[0018] As an optional technical solution of this utility model, the inner wall of the U-shaped groove 2 has two symmetrically arranged snap-fit ​​holes 10. Both snap-fit ​​rods 9 pass through the locking frame 6 and snap-fit ​​with the Bluetooth speaker body 1 through the snap-fit ​​holes 10. The snap-fit ​​holes 10 on the inner wall of the U-shaped groove 2 provide a precise snap-fit ​​adaptation structure for the snap-fit ​​rods 9, so that the snap-fit ​​rods 9 can stably pass through the locking frame 6 and form a reliable snap-fit ​​with the Bluetooth speaker body 1, effectively limiting the displacement of the assembly frame 3, avoiding the assembly frame 3 from loosening due to vibration and collision during speaker use, ensuring the stability of the corresponding position of the protective net 4 and the speaker 5, and ensuring that the protective function does not fail.

[0019] As an optional technical solution of this utility model, the inner wall of the U-shaped groove 2 is provided with two symmetrically arranged guide grooves 11. Guide strips 12 are fixedly connected to both sides of the assembly frame 3. The two guide strips 12 are slidably connected to the Bluetooth speaker body 1 through the two guide grooves 11 respectively. The guide grooves 11 of the U-shaped groove 2 and the guide strips 12 of the assembly frame 3 form a sliding fit structure, which provides directional guidance for the assembly and disassembly of the assembly frame 3, and prevents the assembly frame 3 from deviating or getting stuck when sliding. This not only improves the smoothness of the disassembly and assembly of the protective net 4, but also ensures that the protective net 4 is accurately aligned with the speaker 5 after assembly, avoiding the impact of positional deviation on sound quality transmission or protection effect.

[0020] As an optional technical solution of this utility model, the internal fixed connection of the assembly frame 3 includes two corresponding upper and lower reinforcing strips 13. The two reinforcing strips 13 are staggered with several speakers 5. The front of the reinforcing strips 13 is fixedly connected to the protective net 4. The fixed connection between the reinforcing strips 13 and the protective net 4 in the assembly frame 3 can significantly enhance the structural strength of the protective net 4, improve its impact resistance and deformation resistance, and prevent the protective net 4 from being damaged by external force collision. At the same time, the staggered arrangement of the reinforcing strips 13 and the speakers 5 can avoid the sound-emitting area of ​​the speakers 5 while strengthening the protection, without obstructing the sound propagation path, and ensuring the integrity and clarity of the speaker's sound quality output.

[0021] As an optional technical solution of this utility model, the bottom of the assembly frame 3 is fixedly connected to two card plates 14. Both card plates 14 are inserted into the inner wall of the U-shaped groove 2. The card plates 14 at the bottom of the assembly frame 3 are inserted into the inner wall of the U-shaped groove 2 and locked with the top of the card rod 9 to form a "double fixing" structure, which further improves the connection stability between the assembly frame 3 and the Bluetooth speaker body 1, prevents the assembly frame 3 from moving up and down during use, avoids the protective net 4 from falling off the corresponding area of ​​the speaker 5 due to the displacement of the assembly frame 3, and ensures that the protective function remains effective.

[0022] As an optional technical solution of this utility model, a frame 15 is fixedly connected to the top of the locking frame 6, and a rubber plug 16 is inserted into the inner wall of the frame 15. The top surfaces of the two control plates 7 are in contact with the bottom surfaces of the rubber plugs 16. The frame 15 at the top of the locking frame 6 provides a stable mounting carrier for the rubber plugs 16. The rubber plugs 16 are in contact with the top surfaces of the control plates 7, which can not only prevent dust and impurities from entering the interior of the locking frame 6, thus preventing the control plates 7 and springs 8 from becoming stuck or malfunctioning due to dust accumulation, but also form a flexible limit on the control plates 7, preventing the control plates 7 from moving accidentally in non-operational states, which could cause the locking rod 9 to loosen, thus ensuring the reliability of the locking structure.

[0023] A wireless stereo Bluetooth speaker works as follows: 1) The current protective netting is easy to install and remove, reducing maintenance difficulty and cost. When the protective netting 4 has accumulated too much dust or is damaged and needs to be repaired, first remove the rubber plug 16 inside the frame 15.

[0024] 2): Press the two control plates 7 to compress the springs 8 and drive the locking rod 9 to disengage from the locking hole 10 on the inner wall of the U-shaped groove 2. After unlocking, pull the locking frame 6 upward.

[0025] 3): The assembly frame 3 and the protective net 4 slide upward along the U-shaped groove 2. The guide strips 12 on both sides of the assembly frame 3 move smoothly along the guide groove 11, and the bottom plate 14 disengages from the U-shaped groove 2 to complete the disassembly.

[0026] In summary, this wireless stereo Bluetooth speaker allows for easy installation and removal of the protective mesh, reducing maintenance difficulty and cost. When the protective mesh 4 accumulates too much dust or becomes damaged and needs to be repaired, first remove the rubber plug 16 inside the frame 15, then press the two control plates 7 to compress the spring 8 and cause the locking rod 9 to disengage from the locking hole 10 on the inner wall of the U-shaped groove 2. After unlocking, pull the locking frame 6 upwards, which will cause the assembly frame 3 and the protective mesh 4 to slide upwards along the U-shaped groove 2. The guide strips 12 on both sides of the assembly frame 3 will move smoothly along the guide groove 11, and the bottom locking plate 14 will disengage from the U-shaped groove 2 to complete the disassembly. After cleaning or replacing the protective mesh 4, align the assembly frame 3 with the U-shaped groove 2, so that the guide strip 12 is embedded in the guide groove 11 and the locking plate 14 is inserted into the inner wall of the U-shaped groove 2. Push the locking frame 6 until the locking rod 9 is aligned with the locking hole 10. The spring 8 will reset and cause the locking rod 9 to insert into the locking hole 10 to achieve locking. Finally, put the rubber plug 16 back into the frame 15. The entire process requires no tools, avoiding structural damage during disassembly using traditional glue bonding methods, making the maintenance of the protective net 4 more efficient and extending the overall lifespan of the speaker. It enhances the stability of the protective and sound-generating structures, ensuring high-quality sound output. During assembly, the assembly frame 3 achieves precise positioning through the cooperation of the guide strip 12 and guide groove 11. The insertion of the bottom clamping plate 14 into the U-shaped groove 2 and the snap-fitting of the snap-fitting rod 9 into the snap-fitting hole 10 form multiple fixations, ensuring that the assembly frame 3 and the protective net 4 are firmly attached to the Bluetooth speaker body 1, preventing displacement due to vibration during use. The reinforcing strip 13 inside the assembly frame 3 is fixedly connected to the protective net 4, enhancing its impact resistance and ensuring that its staggered arrangement with the speaker 5 does not obstruct sound transmission. The rubber plug 16 adheres to the top surface of the control board 7, preventing dust from entering the locking frame 6 and affecting the operation of the control board 7 and spring 8, while also limiting the movement of the control board 7. The coordinated action of all components ensures that the protective net 4 stably protects the speaker 5, while also guaranteeing the stability and integrity of the speaker 5's sound output, thus enhancing the listening experience.
