[0036] The following describes in detail preferred embodiments of the present invention in conjunction with the accompanying drawings to make the advantages and features of the present invention more easily understood by those skilled in the art. It should be noted that the description of these embodiments is intended to facilitate understanding of the present invention and does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0037] When manufacturing audio equipment like speakers, they need to be fixed in place to ensure proper function. The mounting position and orientation of the speaker have a significant impact on the sound quality and performance, and clamps are used to achieve this precise mounting.

[0038] To address the problems caused by the diversity of speaker fixtures, the following aspects can be considered: (1) Standardized design: by unifying the design standards and specifications of fixtures, the number of types can be reduced and management costs can be lowered; (2) Modular design: the fixtures can be designed as detachable and combinable modular structures to accommodate speakers of different models and specifications.

[0039] The speaker fixing device includes a base 1, an adjustment member 2, a first clamping plate 3, a second clamping plate 36, and a rotating handle 6. The rotating handle 6 is fixedly connected to one end of the adjustment member 2 to drive the adjustment member 2 to rotate. The first clamping plate 3, the second clamping plate 36, and the base 1 form an installation space 7 for accommodating and fixing the speaker 100.

[0040] Furthermore, the adjusting member 2 includes a first thread 22, a second thread 24, and a rod 21 located between the first thread 22 and the second thread 24. The rod 21 is disposed on the base 1, and the first thread 22 and the second thread 24 are oriented in opposite directions. The adjusting member 2 is connected to the first clamping plate 3 via the first thread 22, and to the second clamping plate 36 via the second thread 24. The adjusting member 2 drives the first clamping plate 3 and the second clamping plate 36 toward or away from each other during rotation, thereby adjusting the size of the installation space 7. Furthermore, the base 1 includes a first base 11 and a second base 12, which are fixedly connected by a fastener 4, specifically a hexagonal head screw and a hexagonal nut. A receiving groove 13 for accommodating the rod 21 is formed in the middle of the first base 11 and the second base 12.

[0041] The first clamping plate 3 and the second clamping plate 36 are movably disposed on the base 1 along a first straight line. The first clamping plate 3 is provided with two positioning members 33 that prevent the speaker 100 from rotating circumferentially. The positioning members 33 are disposed on either side of the interface 101 of the speaker 100. The first clamping plate 3 and the second clamping plate 36 are spaced apart along the first straight line. The "first straight line" herein refers to a straight line parallel to the long side of the base 1. The first clamping plate 3 and the second clamping plate 36 each have a first end 34 and a second end 35. The magnetic bowl 102 of the speaker 100 is located between the second end 35 of the first clamping plate 3 and the second end 35 of the second clamping plate 36. The first ends 34 of the first clamping plate 3 and the second clamping plate 36 are respectively threadedly connected to the adjusting member 2. Specifically, the first end 34 of the first clamping plate 3 is provided with a through hole 32, which is provided with a first internal thread that mates with the first thread 22. The first end 34 of the second clamping plate 36 is provided with a through hole 32, which is provided with a second internal thread that mates with the second thread 24.

[0042] Gaskets 31 , specifically rubber pads, are provided between the first and second clamping plates 3 , 36 and the loudspeaker 100 to prevent damage to the loudspeaker 100 . The rubber pads are installed on the second ends 35 of the first and second clamping plates 3 , 36 by interference fit.

[0043] The speaker fixing device further includes a magnet 5 for generating magnetic attraction with the magnetic bowl 102 . The magnet 5 is located below the base 1 , specifically below the first base 11 .

[0044] The speaker fixing device has a first working state and a second working state. In the first working state, the two clamping plates 3 move away from each other to clamp the first speaker; in the second working state, the two clamping plates 3 move closer to each other to clamp the second speaker, and the outer diameter of the magnetic bowl of the first speaker is larger than the outer diameter of the magnetic bowl of the second speaker. When the speaker to be replaced is smaller, the two clamping plates 3 can be moved closer to each other by turning the rotating handle 6 clockwise (or counterclockwise) to clamp the smaller speaker. When the speaker to be replaced is larger, the two clamping plates 3 can be moved away from each other by turning the rotating handle 6 counterclockwise (or clockwise), and the larger speaker can be placed between the two clamping plates 3. The rotating handle 6 can then be turned clockwise (or counterclockwise) to bring the two clamping plates 3 closer to each other to clamp the larger speaker. This makes it easier to use when replacing speakers of different sizes, reduces the design, manufacturing, and management costs of the fixing device, and improves production efficiency.

[0045] Due to the single type of fixtures used to install speakers on factory assembly lines, when installing different types of speakers, a large number of fixtures need to be replaced simultaneously, which is time-consuming, labor-intensive, and costly. The speaker fixing device of this embodiment rotates the adjusting member 2 by turning the rotating handle 6. The adjusting member 2 has threads on both sides with opposite rotation directions, which enables the clamping plates 3 to move toward or away from each other, thereby clamping the speaker. When the speaker needs to be replaced, if the replacement speaker model is smaller, the rotating handle is turned clockwise to move the clamping plates 3 toward each other; if the replacement speaker model is larger, the rotating handle is turned counterclockwise to move the clamping plates 3 away from each other. The positioning member 33 is clamped on both sides of the interface 101 to prevent the speaker from rotating circumferentially. It has flexible adjustability, allowing the speaker to be quickly and conveniently positioned and clamped. The device has a simple structure and can clamp speakers of various sizes.

[0046] The speaker fixing device of this embodiment has at least the following advantages:

[0047] (1) Enhanced flexibility: The design of the speaker fixture enables it to adapt to more models of speakers, improving the flexibility of the production line and enabling companies to respond to changes in market demand more quickly and conveniently;

[0048] (2) Cost reduction: By reducing the types of fixtures and lowering management costs, companies can save a lot of money and use it for other investments or improving product quality;
