Description

Technical Field

[0001] This utility model relates to the field of Bluetooth speaker technology, specifically a Bluetooth speaker that is easy to repair. Background Technology

[0002] Bluetooth speakers refer to audio devices with built-in Bluetooth chips that use Bluetooth connections instead of traditional wired connections. They connect to Bluetooth playback devices such as mobile phones, tablets, and laptops for convenient and quick playback. Currently, Bluetooth speakers are mainly portable speakers, and their appearance is generally small and portable. Bluetooth speaker technology has gradually gained attention and acceptance from consumers due to its user-friendly features. Most Bluetooth speakers on the market are mono speakers (single speaker unit), but some multi-channel speakers (two or more speaker units) with excellent sound quality have also emerged.

[0003] Currently, traditional Bluetooth speakers typically employ a fully enclosed or multi-screw-fixed structure, requiring additional tools to disassemble the entire casing during repairs. This makes the repair process cumbersome and prone to damaging the casing or stripping screws. Some speakers use tight clips or glue to improve drop resistance, but this increases the difficulty of repairs. Speakers with simple connection structures are prone to loosening during frequent use. In addition, existing speaker casings and internal components are mostly designed with symmetrical connections, which may lead to misalignment of components or functional failure during repairs.

[0004] Therefore, it is necessary to research a Bluetooth speaker that is easy to repair. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a Bluetooth speaker that is easy to maintain, which has the advantage of using an embedded positioning structure to enable quick disassembly and assembly of the Bluetooth speaker, thereby improving work efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a Bluetooth speaker that is easy to repair, comprising a speaker enclosure, a maintenance port on the rear side of the speaker enclosure, a snap-fit ​​groove on the top of the speaker enclosure, a sealing plate snapping onto the top of the snap-fit ​​groove, a protective frame fitted on the surface of the speaker enclosure, an installation groove on the front of the protective frame, the installation groove snapping onto the speaker enclosure, symmetrically formed insertion openings on one side of the maintenance port and the sealing plate, and an insertion groove on the wall of the maintenance port on the other side, symmetrically formed insertion strips on the wall of the installation groove, the insertion strips snapping onto the insertion opening and the insertion groove respectively, symmetrically formed positioning grooves on the back of the speaker enclosure, symmetrically formed positioning holes on the back of the protective frame, a torsion post rotatably connected to the positioning hole via a bearing, a post sleeve threadedly connected to the surface of the torsion post, the other end of the post sleeve penetrating the positioning hole and cooperating with the positioning groove, a limit groove formed on the inner wall of the positioning hole, a limit ring fixedly connected to the surface of the post sleeve, and the limit ring slidingly connected to the limit groove.

[0007] As a preferred embodiment of this utility model, the protective frame has a buffer groove on its front side, and the buffer groove is located directly below the mounting groove. The top and bottom of the buffer groove are fixedly connected to a fixing post, and a rubber block is fixedly connected between every two symmetrical fixing posts. A buffer spring is sleeved on the surface of the rubber block.

[0008] As a preferred embodiment of this utility model, a damping disc is symmetrically fixedly connected to the surface of each pair of symmetrical fixed columns, and the same protective sleeve is fitted onto the surface of the two symmetrical damping discs, with the protective sleeve slidably connected to the damping disc.

[0009] As a preferred embodiment of this invention, a fastening spring is fitted onto the surface of the torsion column, and the fastening spring is located outside the limiting ring.

[0010] As a preferred embodiment of this utility model, the top and bottom of the mounting groove are symmetrically provided with anti-foolproof grooves, and the top and bottom of the speaker cabinet are symmetrically fixedly connected with anti-foolproof strips, and the anti-foolproof strips are slidably connected to the anti-foolproof grooves.

[0011] As a preferred embodiment of this invention, shock-absorbing pads are fixedly connected to the four corners of the bottom of the protective frame, and a handle is fixedly connected to the top of the protective frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1.

[0016] 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.

[0017] like Figures 1 to 4As shown, this utility model provides a Bluetooth speaker that is easy to repair, including a speaker body 1. A maintenance port 2 is provided on the rear side of the speaker body 1. A snap-fit ​​groove 3 is provided on the top of the speaker body 1, and a sealing plate 4 is snapped onto the top of the snap-fit ​​groove 3. A protective frame 5 is fitted onto the surface of the speaker body 1, and a mounting groove 6 is provided on the front of the protective frame 5, which snaps into the speaker body 1. Embedding openings 7 are symmetrically provided on the surfaces of the maintenance port 2 and the sealing plate 4 on one side. An embedding groove 8 is provided on the opening wall of the maintenance port 2 on the other side. Embedding strips 9 are symmetrically provided on the groove wall of the mounting groove 6, and the embedding strips 9 respectively embed into the embedding opening 7 and the sealing plate 4. The speaker enclosure 1 is symmetrically provided with positioning grooves 10 on the back side and positioning holes 11 on the back side of the protective frame 5. A torsion column 12 is rotatably connected to the positioning hole 11 through a bearing. A column sleeve 13 is threadedly connected to the surface of the torsion column 12, and the other end of the column sleeve 13 passes through the positioning hole 11 and cooperates with the positioning groove 10. A limit groove 14 is provided on the inner wall of the positioning hole 11. A limit ring 15 is fixedly connected to the surface of the column sleeve 13, and the limit ring 15 is slidably connected to the limit groove 14. The speaker enclosure 1 is the core component and integrates electronic components such as Bluetooth module and speaker.

[0018] refer to Figure 1 The protective frame 5 has a U-shaped buffer groove 16 on the front, and the buffer groove 16 is located directly below the mounting groove 6. The top and bottom of the buffer groove 16 are fixedly connected to the fixing posts 17. A rubber block 18 is fixedly connected between every two symmetrical fixing posts 17. A buffer spring 19 is sleeved on the surface of the rubber block 18.

[0019] As a technical optimization of this utility model, the combination of buffer groove 16, fixed column 17, rubber block 18 and buffer spring 19 can reduce the resonance amplitude of the speaker cabinet 1 and improve the purity of sound quality when the speaker cabinet 1 is working. At the same time, continuous vibration may cause internal components to loosen or solder joints to fatigue. This design reduces vibration transmission and extends the life of components.

[0020] refer to Figure 1 A damping disc 20 is symmetrically fixed to the surface of each pair of symmetrical fixed columns 17. The surface of the two symmetrical damping discs 20 is covered with the same protective sleeve 21, and the protective sleeve 21 is slidably connected to the damping disc 20.

[0021] As a technical optimization of this utility model, the vibration energy is consumed by the sliding friction between the damping disc 20 and the protective sleeve 21, thereby suppressing the resonance of the speaker cabinet 1 during operation, improving the stability of sound quality and reducing structural noise.

[0022] refer to Figure 4A fastening spring 22 is fitted on the surface of the torsion post 12, and the fastening spring 22 is located outside the limiting ring 15.

[0023] As a technical optimization of this utility model, the pre-tightening force is provided by the fastening spring 22 to prevent the torsion column 12 from loosening due to vibration, ensuring the connection stability between the column sleeve 13 and the positioning groove 10, and extending the service life.

[0024] refer to Figure 2 and Figure 3 The top and bottom of the mounting slot 6 are symmetrically provided with anti-foolproof slots 23, and the top and bottom of the speaker cabinet 1 are symmetrically fixedly connected with anti-foolproof strips 24, and the anti-foolproof strips 24 are slidably connected with the anti-foolproof slots 23.

[0025] As a technical optimization of this utility model, the anti-misfit groove 23 and the anti-misfit strip 24 are set to ensure that the protective frame 5 can only be installed in the correct direction, so as to avoid structural damage or functional failure due to misinstallation.

[0026] refer to Figure 1 Shock-absorbing pads are fixedly connected to the four corners of the bottom of the protective frame 5, and a handle is fixedly connected to the top of the protective frame 5.

[0027] As a technical optimization of this utility model, the installation of shock-absorbing pads reduces friction and vibration transmission between the speaker cabinet 1 and the contact surface, thereby improving placement stability. The installation of handles facilitates user movement and carrying of the speaker, enhancing the product's practicality.

[0028] The working principle and usage process of this utility model are as follows: When the Bluetooth speaker needs to be repaired, first rotate the two torsion pins 12. Since the limiting ring 15 on the pin sleeve 13 can only slide linearly within the limiting groove 14, the rotation of the torsion pin 12 causes the pin sleeve 13 to slide linearly into the positioning hole 11 and move away from the positioning groove 10 on the speaker body 1. Then, the speaker body 1 can be pulled out from the mounting groove 6. At this time, the embedding groove 8 and the embedding opening 7 are respectively separated from the embedding strip 9, and the anti-fooling strip 24 is completely separated from the anti-fooling groove 23. After the speaker body 1 is completely pulled out, it can be pulled upward from the snap-fit ​​groove 3 through the embedding groove 8 on the sealing plate 4, which makes it convenient for the staff to repair the internal components of the speaker body 1. After the repair is completed, first reset the sealing plate 4, and then insert the speaker body 1 into the mounting groove 6 of the protective frame 5 in the reverse operation. At this time, it should be noted that the embedding opening 7 needs to be inserted into the mounting groove 6 of the protective frame 5. Slide the insert strip 9 from left to right until it cannot move. At this time, the insert groove 8 abuts against the insert strip 9, which can achieve the effect of pre-positioning and align the positioning groove 10 with the positioning hole 11. The movement trajectory of the sealing plate 4 will be restricted by the mounting groove 6, thus ensuring that it cannot be opened accidentally. Then, rotate the two torsion pillars 12 in the opposite direction to make the pillar sleeve 13 move in the opposite direction and be inserted into the mounting groove 6 of the speaker cabinet 1, thereby completing the installation of the speaker cabinet 1. At this time, the fastening spring 22 pre-tightens the torsion pillars 12 to prevent loosening. In daily use, the buffer spring 19 and the rubber block 18 are connected in parallel in the buffer groove 16 to absorb the energy generated by the speaker vibration when the speaker cabinet 1 is working, reducing the resonance of the speaker cabinet 1. The sliding friction between the damping disc 20 and the protective sleeve 21 further dissipates the vibration energy, forming a secondary damping, which can extend the service life of the speaker cabinet 1.

[0029] It should be noted that the U-shaped buffer groove 16 effectively controls vibration through a two-stage buffering system of "internal elastic energy absorption + damping dissipation." The vibration transmission problem of the fixed column 17 is gradually weakened through the isolation of the rubber block 18, the force relief of the buffer spring 19, and the frictional dissipation of the damping disc 20, ultimately achieving the purpose of reducing resonance in the speaker cabinet 1 and protecting internal components. That is, the structure of the U-shaped buffer groove 16 does not directly determine the buffering method; its core function is to provide installation space for the internal buffering components. The actual buffering is achieved by the combination system of the rubber block 18, buffer spring 19, damping disc 20, and protective sleeve 21 within the groove. The specific process is as follows: Primary buffer: elastic element absorbs energy. The rubber block 18 and the buffer spring 19 inside the buffer groove 16 are connected in parallel, and their ends are fixed to the top and bottom of the buffer groove 16 by fixing posts 17. When the speaker vibrates and generates an impact force: the buffer spring 19 absorbs part of the vibration energy through elastic deformation of stretching or compression; the rubber block 18 further absorbs energy through the elastic deformation of its own material (such as compression and rebound), and at the same time dissipates part of the vibration (converting it into heat energy) by utilizing the high damping characteristics of rubber. Secondary buffer: damping structure dissipation The damping disc 20 on the surface of the fixed column 17 forms a sliding friction pair with the protective sleeve 21. When the vibration is transmitted to the fixed column 17, the damping disc 20 shakes slightly with the fixed column 17 and generates friction with the protective sleeve 21, dissipating the remaining vibration energy through friction and further weakening the force of the vibration transmitted to the protective frame 5.

[0030] Although the two ends of the fixed column 17 are fixed in the buffer groove 16, which may theoretically become a vibration transmission path, the vibration transmitted by it has been greatly weakened by the multi-level structure. That is, the rubber block 18 on the surface of the fixed column 17 is not just for decoration. It tightly wraps the fixed column 17. When the vibration is transmitted from the fixed column 17 to the rubber block 18, the low rigidity of the rubber will "soften" the vibration transmission and reduce the vibration frequency and amplitude. The molecular friction inside the rubber further consumes vibration energy, reducing the transmission to the buffer groove 16 and the protective frame 5. The buffer spring 19 also provides force relief. In addition, the buffer spring 19 is sleeved on the outside of the rubber block 18, and together with the rubber block 18, it bears the vibration impact force. The elastic deformation of spring 19 disperses the force on fixed column 17, preventing concentrated transmission of vibration; the stiffness difference between spring 19 and rubber block 18 creates a "frequency misalignment effect", which disrupts the resonance condition of vibration and reduces transmission efficiency; at the same time, the sliding friction between damping disc 20 on fixed column 17 and protective sleeve 21 performs secondary treatment on any low-frequency vibration that may remain on fixed column 17, ensuring that the vibration transmitted to protective frame 5 is minimized.
