Abstract
Description
Technical Field
[0001] This utility model relates to the field of speaker technology, and in particular to a portable clip-on speaker. Background Technology
[0002] With the growing demand for mobile work and entertainment, laptops have become core devices for users' daily use. However, their built-in speakers, due to size and design limitations, generally suffer from thin sound effects, insufficient bass, and limited volume output, failing to meet users' needs for a high-quality audio experience. To address this, various external portable speakers have emerged on the market, among which clip-on speakers are favored because they can be directly fixed to the edge of the screen, saving desktop space.
[0003] However, existing clip-on speakers still have the following shortcomings in their structural design: traditional clamping mechanisms typically use a fixed design, making it difficult to adapt to screen edges of different thicknesses, and they lack angle adjustment functionality, resulting in limited speaker position and directivity after installation, affecting sound propagation. Some clamping components are integrated with the speaker body, leading to increased size, making it difficult to meet lightweight requirements, and hindering repair or component replacement. Utility Model Content
[0004] This invention provides a portable clip-on speaker with optimized structure, combining flexible adjustment and stable clamping, to enhance the user experience.
[0005] The technical solution adopted by this utility model is as follows: a portable clip-on speaker, including a clip base and a clip plate rotatably connected thereto. The clip base and the clip plate are rotatably connected by a rotating shaft. A retaining spring connected to the clip base and the clip plate is sleeved on the outside of the rotating shaft. A vertical rod is fixedly installed on the clip plate. A mounting bushing is provided at the top of the vertical rod. A connecting column is movably connected inside the mounting bushing. One end of the connecting column is rotatably connected to the speaker body.
[0006] As a further improvement of this utility model, one end of the connecting column is a universal joint installed inside the mounting bushing, and the other end of the connecting column is provided with an external thread and is rotatably connected to the speaker body through a bearing.
[0007] As a further improvement of this utility model, an adjustment knob is threadedly connected to one side of the mounting bushing, and the adjustment knob presses against the mounting bushing to fix the universal joint in position within the mounting bushing.
[0008] As a further improvement of this utility model, a fastening knob is threaded onto the external thread of the connecting post, and the fastening knob fixes the position of the speaker body on the connecting post.
[0009] As a further improvement of this utility model, the middle part of the vertical rod is an electric telescopic rod.
[0010] The beneficial effects of this utility model are as follows: Through the combined design of the universal joint and the adjustment knob, users can freely adjust the horizontal and tilt angles of the speaker, accurately positioning the sound field direction. After the adjustment knob presses and secures the universal joint, it effectively prevents displacement caused by external forces, ensuring the stability and directivity of sound propagation and significantly improving the listening experience. The linkage structure of the rotating shaft and the retaining spring allows the clamp and plate to adapt to screen edges of different thicknesses. The elastic rebound force of the retaining spring provides continuous clamping force, preventing loosening and detachment. The combination of the vertical rod and the electric telescopic rod further supports height adjustment, adapting to diverse usage scenarios. Attached Figure Description

[0016] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly mentioned in this specification are defined relative to their structure and are relative concepts. Therefore, they may vary depending on their location and usage; thus, these or other directional terms should not be interpreted as restrictive terms.
[0017] The singular forms “a,” “the,” and “the” used in this specification are intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.
[0018] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0019] This utility model provides the following: Figure 1-4 The portable clip-on speaker shown includes a clip 1 and a clip plate 2 rotatably connected thereto. The clip 1 and the clip plate 2 are rotatably connected by a rotating shaft 3. A retaining spring 4 connected to the clip 1 and the clip plate 2 is sleeved on the outside of the rotating shaft 3. A vertical rod 5 is fixedly installed on the clip plate 2. A mounting sleeve 6 is provided at the top of the vertical rod 5. A connecting post 7 is movably connected inside the mounting sleeve 6. One end of the connecting post 7 is rotatably connected to the speaker body 8.
[0020] like Figure 3 and Figure 4 As shown, in this utility model, one end of the connecting post 7 is a universal joint 701 installed inside the mounting sleeve 6, and the other end of the connecting post 7 has an external thread and is rotatably connected to the speaker body 8 through the bearing 9. An adjustment knob 10 is threadedly connected to one side of the mounting sleeve 6, and the adjustment knob 10 presses the mounting sleeve 6 to fix the position of the universal joint 701 inside the mounting sleeve 6; a fastening knob 11 is threadedly connected to the connecting post 7 at the external thread, and the fastening knob 11 fixes the position of the speaker body 8 on the connecting post 7.
[0021] In this utility model, the middle part of the vertical rod 5 is an electric telescopic rod.
[0022] Working Principle: In practical implementation, the user can adjust the pressure of the mounting sleeve 6 on the universal joint 701 by rotating the adjustment knob 10, thereby changing the horizontal angle of the speaker body 8. Through the design of the universal joint 701, the speaker body 8 can tilt and rotate within a certain range. The user can adjust it to the optimal sound propagation angle according to actual needs. After adjustment, tighten the adjustment knob 10 to firmly press the mounting sleeve 6, preventing the universal joint 701 from shifting due to external force and ensuring the directivity and stability of the speaker body 8. Simultaneously, the user can adjust the position of the speaker body 8 on the connecting column 7 by rotating the fastening knob 11, further fine-tuning the rotation angle of the speaker body 8 to meet the sound effect requirements of different scenarios. Furthermore, the electric telescopic rod design allows the length of the vertical rod 5 to be freely adjusted, enabling the user to flexibly adjust the height of the speaker body 8 according to screen height or desktop space to adapt to diverse usage scenarios.
