Description

Technical Field

[0001] This utility model belongs to the field of audio equipment manufacturing technology, specifically relating to a speaker clamping fixture. Background Technology

[0002] A speaker is an electronic device that converts electrical signals into sound signals. It is widely used in home entertainment, office meetings, public address systems, and other fields. Its core function is to amplify and propagate sound through internal speaker units to meet users' audio playback needs. The speaker manufacturing process typically involves pre-processing the outer casing and assembling internal components. During surface treatments such as sanding, painting, and screen printing on the speaker casing, or during the precise installation of internal components such as speaker units and circuit boards inside the casing, clamping fixtures are required to secure the speaker and ensure operational precision.

[0003] Currently, most speaker clamping fixtures are fixed structures, which mainly include a base with two positioning plates on the base. A positioning space is formed between the two positioning plates to limit the displacement of the speaker. Elastic clamping elements, such as springs, are set on the positioning plates. When the speaker is placed in the positioning space, the elastic clamping elements undergo elastic deformation and clamp the speaker, thus achieving speaker positioning.

[0004] However, depending on the usage scenario and structural differences, speakers can be divided into many types. Different types of speakers have certain differences in length. When the same production line produces speakers of various length specifications, the clamping fixture cannot adjust the positioning space to adapt to different specifications of speakers. Operators need to disassemble the original clamping fixture and replace it with a new clamping fixture of different specifications. Frequent clamping fixture replacement will affect production efficiency and easily cause positioning errors. Utility Model Content

[0005] To address the shortcomings of the prior art, this utility model provides a speaker clamping fixture. The adjusting component can adjust the position of the elastic baffle, thereby adjusting the size of the positioning area. The speaker clamping fixture is adaptable to speakers of different specifications, eliminating the need for operators to frequently change the clamping fixture and improving production efficiency.

[0006] The technical effects to be achieved by this utility model are realized through the following technical aspects: This utility model provides a speaker clamping fixture, including an elastic baffle and an abutment portion. One side of the abutment portion is provided with a positioning area for fixing the speaker. When the abutment portion is squeezed, the abutment portion elastically clamps the speaker. An adjustment component is provided on one side of the elastic baffle. The adjustment component includes an adjustment rod. The elastic baffle moves along the adjustment rod to adjust the size of the positioning area. A locking structure is provided between the elastic baffle and the adjustment rod to restrict the movement of the elastic baffle.

[0007] In some implementations, the adjusting rod is provided with a locking tooth, and the locking structure includes: a locking seat, which passes through the adjusting rod and slides along the adjusting rod, and the elastic baffle is connected to the locking seat; a tooth block, which is disposed in the locking seat and engages with the locking tooth; and a movable member, which is disposed between the locking seat and the tooth block, and the movable member drives the tooth block to disengage from the locking tooth or engage with the locking tooth.

[0008] In some implementations, the locking seat has a bottom hole, and the movable member drives the toothed block to move within the bottom hole.

[0009] In some implementations, the locking seat has a receiving cavity, and the movable member includes: a movable block disposed in the receiving cavity, the toothed block disposed on the movable block; and an elastic member disposed between the movable block and the locking seat. When the movable block presses the elastic member, the movable block enters the receiving cavity, and the toothed block disengages from the locking tooth.

[0010] In some implementations, the toothed block is detachably connected to the movable block.

[0011] In some implementations, the elastic element is a spring, the locking seat includes a mounting portion, the mounting portion has a mounting groove, and the spring is disposed in the mounting groove.

[0012] In some implementations, the movable block is provided with a guide portion, which passes through the spring to guide the extension and retraction of the spring.

[0013] In some implementations, the elastic baffle includes a connecting part that is detachably connected to the locking seat, and the connecting part has a pressing hole, through which the movable block passes.

[0014] In some implementations, a deformation space is formed between the abutting portion and the connecting portion.

[0015] In some implementations, a tooling plate is included, the elastic baffle and the adjusting component are both disposed on the tooling plate, a connecting seat is provided on the tooling plate, and the adjusting rod is detachably connected to the connecting seat.

[0016] In summary, this utility model has at least the following advantages: The speaker clamping fixture provided by this utility model allows for the adjustment of the size of the positioning area by a flexible baffle via an adjusting component before positioning the speaker. During adjustment, the flexible baffle moves along the adjusting rod. When the flexible baffle reaches the appropriate position, a locking structure restricts its movement along the adjusting rod, locking the flexible baffle and inserting the speaker into the positioning area. The abutment portion deforms under the pressure of the speaker, clamping the speaker under elastic force, thus completing the speaker fixing operation.

[0017] The adjustment component allows for the positioning of speakers of different sizes by adjusting the position of the elastic baffle, enabling the production of speakers of various lengths on the same production line. Simultaneously, it eliminates the need for operators to disassemble and replace clamping fixtures, improving speaker production efficiency. The elastic baffle, along the adjustment rod, allows for fine-tuning, ensuring precise speaker positioning. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] Example 1: Please see Figure 1 The speaker clamping fixture of this utility model can be used in processes that require speaker positioning, such as speaker shell pretreatment and internal component assembly, and can be adapted to speakers of different specifications, making it convenient to use.

[0029] The speaker clamping fixture of this utility model includes an elastic baffle 1. In some specific embodiments, a fixed baffle is provided on one side of the elastic baffle 1. The elastic baffle 1 includes an abutment part 11. A positioning area 12 for fixing the speaker is provided between the abutment part 11 and the fixed baffle. When the speaker is inserted into the positioning area 12, the speaker squeezes the abutment part 11, and the abutment part 11 elastically clamps the speaker. The abutment part 11 abuts against the outer wall of the speaker.

[0030] An adjustment component 2 is provided on one side of the elastic baffle 1. The adjustment component 2 can adjust the position of the elastic baffle 1, thereby adjusting the size of the positioning area 12. The elastic baffle 1 can clamp and fix speakers of different specifications. The adjustment component 2 includes an adjustment rod 21, which is specifically set horizontally. The elastic baffle 1 moves along the length of the adjustment rod 21 to adjust the size of the positioning area 12. The adjustment rod 21 can achieve an adjustment range of 180mm. It should be understood that this is not a specific limitation on the adjustment range of the adjustment rod 21. The operator can adjust the length of the adjustment rod 21 according to the actual speaker specifications. A locking structure 3 is provided between the elastic baffle 1 and the adjustment rod 21 to limit the movement of the elastic baffle 1.

[0031] During adjustment, locking structure 3 releases elastic baffle 1, which moves along adjusting rod 21, moving closer to or further away from fixed baffle to adjust the size of positioning area 12 according to speaker dimensions. Once elastic baffle 1 is in the appropriate position, locking structure 3 locks it in place, securing the speaker into positioning area 12. Elastic baffle 1 thus clamps and fixes the speaker. Compared to traditional fixed speaker clamping fixtures, elastic baffle 1, with its position adjustable via adjusting component 2, can accommodate different speaker sizes. Operators no longer need to frequently disassemble and replace clamping fixtures based on speaker models, enabling rapid product changeovers, increasing efficiency, and allowing the same production line to produce speakers of different sizes, thus reducing production costs.

[0032] Example 2: The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the adjustment component 2 of this utility model. Please refer to [link / reference]. Figures 2-7 .

[0033] Please see Figure 2 In this embodiment, the adjusting rod 21 is provided with a locking tooth 211. Specifically, the locking tooth 211 can be provided at the bottom of the adjusting rod 21 and distributed along the length direction of the adjusting rod 21. The elastic baffle 1 can be displaced and adjusted along the distribution direction of the locking tooth 211.

[0034] Combination Figure 3 and Figure 4 The locking structure 3 includes a locking seat 31, which passes through and slides along the adjusting rod 21. An elastic baffle 1 is connected to the locking seat 31. A toothed block 32 is provided inside the locking seat 31, engaging with a locking tooth 211. A movable member 33 is provided between the locking seat 31 and the toothed block 32, driving the toothed block 32 to disengage from or engage with the locking tooth 211. When the toothed block 32 engages with the locking tooth 211, the locking seat 31 is locked; when the toothed block 32 disengages from the locking tooth 211, the locking seat 31 is unlocked, allowing the elastic baffle 1 to move along the adjusting rod 21. In some specific embodiments, the locking seat 31 has a bottom hole 311. The movable member 33 drives the toothed block 32 to move within the bottom hole 311, providing clearance for the movement of the toothed block 32 and ensuring smooth movement of the toothed block 32 during locking and unlocking.

[0035] When the positioning area 12 is reduced, the movable part 33 moves the toothed block 32 away from the locking tooth 211, the locking seat 31 is unlocked, and the operator can push the locking seat 31 along the adjusting rod 21, causing the elastic baffle 1 to move towards the fixed baffle. After adjusting to the appropriate position, the movable part 33 moves the toothed block 32 back to its original position and engages with the locking tooth 211, the locking seat 31 is locked, the elastic baffle 1 is also fixed, and the speaker can be inserted into the positioning area 12 for fixation. When it is necessary to expand the positioning area 12, the movable part 33 moves the toothed block 32 to unlock the locking seat 31, and the locking seat 31 moves in the opposite direction for adjustment.

[0036] Please see Figure 5 and Figure 6 In a preferred embodiment, the locking seat 31 has a receiving cavity 312. The movable component 33 includes a movable block 331, which is disposed within the receiving cavity 312. A toothed block 32 is disposed on the movable block 331. The movable block 331 moves up and down within the receiving cavity 312, causing the toothed block 32 to move closer to or further away from the locking tooth 211. Specifically, the toothed block 32 and the movable block 331 are detachably connected, for example, by bolts. Operators can disassemble and replace the locking tooth 211 after it wears, making maintenance convenient. Furthermore, the movable block 331 can be a U-shaped block, with the toothed block 32 disposed at the opening of the movable block 331. An adjusting rod 21 passes between the movable block 331 and the toothed block 32. In the locked state, the toothed block 32 can firmly engage with the locking tooth 211, which helps improve the stability of the locking seat 31 after locking.

[0037] An elastic element 332 is provided between the movable block 331 and the locking seat 31. When the movable block 331 presses against the elastic element 332, the elastic element 332 deforms and compresses, allowing the movable block 331 to descend into the receiving cavity 312. The toothed block 32 disengages from the locking tooth 211, and the locking seat 31 is unlocked. When the movable block 331 is released, the elastic element 332 returns to its initial state, the movable block 331 rises back to its original position, the toothed block 32 engages with the locking tooth 211 again, and the locking seat 31 is locked. Through the provision of the elastic element 332, the movable block 331 can automatically reset after movement, resulting in a simple structure and easy operation.

[0038] In some specific embodiments, the elastic element 332 is a spring, and the locking seat 31 includes a mounting portion 313 located within the receiving cavity 312. The mounting portion 313 has a mounting groove 314, and the spring is disposed within the mounting groove 314. The mounting portion 313 provides support for the spring. Furthermore, the movable block 331 is provided with a guide portion 3311, which passes through the spring. When the movable block 331 compresses or releases the spring, the guide portion 3311 guides the spring to extend or retract.

[0039] Please see Figure 7In a preferred embodiment, the elastic baffle 1 includes a connecting portion 13. The connecting portion 13 and the abutting portion 11 can be integrally formed by bending a 1.5mm thick stainless steel plate. The elastic baffle 1 achieves elastic clamping of the speaker through bending elasticity. Specifically, the connecting portion 13 is folded up to the top of the locking seat 31 and fits against the top surface of the locking seat 31. The connecting portion 13 and the locking seat 31 are detachably connected and can be assembled with bolts. A pressing hole 131 is provided on the connecting portion 13, and a movable block 331 passes through the pressing hole 131. The connecting portion 13 is further folded towards the side of the locking seat 31, and the adjusting rod 21 passes through the locking seat 31 and the connecting portion 13 in sequence, which can reduce the possibility of the elastic baffle 1 falling off from the locking seat 31 and the adjusting rod 21.

[0040] In addition, the abutment part 11 is bent, and a deformation space 14 is formed between the abutment part 11 and the connecting part 13. When the speaker is inserted into the positioning area 12, the abutment part 11 is pressed against the connecting part 13. The elastic baffle 1 can ensure the stability of the speaker clamping and compensate for the positioning error of the speaker.

[0041] Example 3: The difference between this embodiment and the above embodiments is that, please refer to [link / reference needed]. Figure 7 The speaker clamping fixture in this embodiment also includes a tooling plate 4, an elastic baffle 1 and an adjustment component 2 disposed on the tooling plate 4. Specifically, there are two sets of adjustment components 2, which are disposed on both sides of the elastic baffle 1 respectively.

[0042] The tooling plate 4 is provided with a connecting seat 41, and a connecting hole is provided on the connecting seat 41. The adjusting rod 21 is inserted into the connecting hole and is detachably connected to the connecting seat 41. Specifically, an adjusting bolt is provided on the connecting seat 41. The adjusting bolt can be used to clamp the adjusting rod 21 with the connecting seat 41, which facilitates the replacement of the adjusting rod 21.
