Abstract
Description
Technical Field
[0001] This utility model relates to the field of notebook audio box technology, and more specifically, to a notebook audio box shock absorption mechanism. Background Technology
[0002] Currently, with the widespread use of laptops in daily life and work, users' demands for laptop audio quality are increasing. When a laptop is running audio functions, the vibration of the speakers in the audio box can cause a series of problems. On the one hand, the vibration generated by the speakers can be transmitted to the inside of the laptop through structural components, interfering with the normal operation of other delicate electronic components and affecting the overall performance stability of the laptop. For example, vibration may cause hard drive read / write abnormalities, resulting in data transmission stutters or errors. On the other hand, the vibration transmitted to the desktop or other devices in contact with the laptop can generate additional noise, which not only affects the user's own audio experience but may also disturb others in the surrounding environment.
[0003] Traditional laptop audio box designs often focus solely on sound quality while neglecting effective vibration management. Even when simple damping measures are incorporated, such as adding ordinary rubber pads between the speaker and the box casing, these measures have limited absorption and buffering capabilities for high-frequency and low-frequency vibrations. They fail to fundamentally address the interference of vibrations on audio signal components, leading to audio distortion during playback and failing to meet users' demands for high-quality audio.
[0004] In view of this, the present invention proposes a vibration damping mechanism for a laptop audio box. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a notebook audio box vibration damping mechanism to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a notebook audio BOX vibration damping mechanism, comprising a BOX assembly installed inside a notebook, the BOX assembly including a BOX upper shell, a vibration damping pad disposed inside the BOX upper shell, a speaker assembled inside the vibration damping pad, the vibration damping pad being glued to the inside of the BOX upper shell, the speaker and the vibration damping pad having a matching structure, and the speaker being glued to the vibration damping pad, the speaker also having an electrically welded connecting wire harness for powering the speaker, a BOX lower shell disposed on one side of the BOX upper shell, the structures of the BOX upper shell and the BOX lower shell being adapted to each other, and the BOX upper shell and the BOX lower shell being ultrasonically fixed together.
[0007] As can be seen, the damping pads at the speaker can dampen audio vibrations, improving the sound quality and stability of the audio box.
[0008] In order to enable the installation of the BOX components and further buffer audio vibration, preferably, a C-shell bracket is provided on one side of the BOX lower shell, and several rubber pads are fixedly provided on the surface of the C-shell bracket. Connecting posts are fixedly provided on the surface of each of the rubber pads. A semi-circular overlapping ring is integrally formed on the outer wall of the connecting post. The same number of shock-absorbing rubber ring structures as the connecting posts are provided at the corners of the BOX lower shell.
[0009] The damping ring structure includes two rubber damping rings distributed vertically, with a buffer ring integrally formed between the two rubber damping rings. The surfaces of the two rubber damping rings are arranged in a ring array and integrally formed with several rubber support ribs. The two rubber damping rings and the buffer ring of the damping ring structure are all sleeved on the connecting column and are fixed to the connecting column by several rubber support ribs. The several rubber support ribs are symmetrically distributed on the surface of the corresponding rubber damping rings. The number of rubber support ribs is set to eight, of which four rubber support ribs are pressed and fixed to the outer wall of the semi-circular overlapping ring, and the other four rubber support ribs are pressed and overlapped on the top of the connecting column.
[0010] The technical effects and advantages of this utility model are as follows:
[0011] Through the multi-stage damping design of the speaker's damping pads and rings, the vibration generated by the audio box can be effectively absorbed and dispersed, reducing the transmission of vibration to the laptop, desktop, or other devices. This avoids device instability or noise interference caused by vibration, effectively reducing the interference of high-frequency and low-frequency vibrations on audio signal components, and preventing audio distortion. The damping effect is dynamically adjusted according to the vibration intensity through the action of multiple damping mechanisms, adapting to vibrations of different frequencies and intensities, providing a more precise damping effect, and meeting diverse audio playback needs.

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.
[0020] As attached Figure 1-6 The illustrated notebook audio box vibration damping mechanism includes a box assembly installed inside the notebook. The box assembly includes a box top shell 1, a vibration damping pad 2 inside the box top shell 1, a speaker 3 inside the vibration damping pad 2, and the vibration damping pad 2 is glued to the inside of the box top shell 1. The speaker 3 is structurally matched with the vibration damping pad 2 and is glued to the vibration damping pad 2. A connecting wire harness for powering the speaker 3 is also electrically soldered onto the speaker 3. A box bottom shell 4 is provided on one side of the box top shell 1. The structures of the box top shell 1 and the box bottom shell 4 are compatible and are ultrasonically fixed together.
[0021] Specifically, in this structure, the BOX assembly consists of a BOX upper shell 1, a shock-absorbing pad 2, a speaker 3, and a BOX lower shell 4. When assembling the BOX assembly, the shock-absorbing pad 2 is first glued to the inside of the BOX upper shell 1. Then, the speaker 3 is glued to the shock-absorbing pad 2. After the connecting wire harness connected to the speaker 3's wires is soldered, the BOX lower shell 4 is installed and ultrasonically fixed to complete the overall installation of the BOX assembly.
[0022] The damping pad 2 at speaker 3 can absorb the vibration generated by speaker 3 audio BOX, reducing the vibration transmitted to the inside of the laptop, desktop or other devices, avoiding device instability or noise interference caused by vibration, effectively reducing the interference of high frequency and low frequency vibration on audio signal structural components, and avoiding audio distortion.
[0023] In this embodiment, as shown in the appendix Figure 1 ,3 As shown in Figures 4 and 5, a C-shell support 5 is provided on one side of the lower shell 4 of the BOX, and several rubber pads 6 are fixedly provided on the surface of the C-shell support 5. A connecting post 7 is fixedly provided on the surface of each of the rubber pads 6. A semi-circular overlapping ring 8 is integrally formed on the outer wall of the connecting post 7. The same number of shock-absorbing rubber ring structures as the connecting posts 7 are provided at the corners of the lower shell 4 of the BOX.
[0024] The damping ring structure includes two rubber damping rings 9 distributed vertically, and a buffer ring 10 integrally formed between the two rubber damping rings 9. The surfaces of the two rubber damping rings 9 are arranged in a ring array and integrally formed with several rubber support ribs 11. The two rubber damping rings 9 and the buffer ring 10 of the damping ring structure are both sleeved on the connecting column 7 and are fixed to the connecting column 7 by several rubber support ribs 11. Several rubber support ribs 11 are symmetrically distributed on the surface of the corresponding rubber damping rings 9. The number of rubber support ribs 11 is set to eight, of which four rubber support ribs 11 are pressed and fixed to the outer wall of the semi-circular overlapping ring 8, and the other four rubber support ribs 11 are pressed and overlapped on the top of the connecting column 7.
[0025] Specifically, in this structure, after the BOX component is assembled, the shock-absorbing rubber ring structure at the lower shell 4 of the BOX is pressed and fixed to the connecting column 7 on the C-shell bracket 5, so that the assembled BOX component is installed on the C-shell bracket 5 and effectively absorbs and buffers audio vibrations.
[0026] Two rubber damping rings 9 and buffer rings 10 belonging to the damping ring structure at 4 locations on the lower shell of the BOX are respectively fitted onto the corresponding connecting post 7 at 4 locations on the lower shell of the BOX. Eight rubber support ribs 11 are symmetrically distributed and integrally formed on the two rubber damping rings 9, so that four of the rubber support ribs 11 are pressed and fixed to the outer wall of the semi-circular overlapping ring 8 of the connecting post 7, and the other four rubber support ribs 11 are pressed and overlapped on the top of the connecting post 7, thus completing the connection between the BOX assembly and the C-shell bracket 5.
[0027] Two rubber damping rings 9 can further absorb the audio vibration generated by the BOX component, and the continuous audio vibration is buffered by the integrally molded buffer ring 10. The eight rubber support ribs 11 can not only play a supporting and fixing role, but also further disperse the vibration brought by the audio.
[0028] Meanwhile, several rubber pads 6 at the bottom of the connecting post 7 can absorb audio vibrations from the connecting post 7, preventing the generated vibrations from being transmitted to the C-shell bracket 5 and to the inside of the laptop, the desktop, or other devices.
[0029] Working principle of this utility model:
[0030] This application provides a notebook audio BOX vibration damping mechanism, wherein the BOX assembly consists of a BOX upper shell 1, a vibration damping pad 2, a speaker 3, and a BOX lower shell 4. During assembly, the vibration damping pad 2 is first glued to the inside of the BOX upper shell 1, and then the speaker 3 is glued to the vibration damping pad 2. The vibration generated by the speaker 3 when it is working is first absorbed by the vibration damping pad 2 around it, thereby reducing the transmission of vibration to the inside of the notebook, the desktop, or other devices, avoiding device instability or noise interference caused by vibration, and effectively reducing the impact of high-frequency and low-frequency vibrations on audio signal structural components, preventing audio distortion.
[0031] A C-shell support 5 is provided on one side of the lower shell 4 of the BOX. Several rubber pads 6 with connecting columns 7 are fixed on the surface of the C-shell support 5. The outer wall of the connecting column 7 has a semi-circular overlapping ring 8. The surface of the lower shell 4 of the BOX is provided with a shock-absorbing rubber ring structure. This structure consists of two rubber shock-absorbing rings 9 that are distributed vertically and integrally formed by buffer rings 10. Several rubber support ribs 11 are distributed in a ring array on the surface of the rubber shock-absorbing rings 9.
[0032] During installation, the two rubber damping rings 9 and the buffer rings 10 of the four damping ring structures on the lower shell of the BOX are fitted onto the corresponding connecting columns 7 of the C-shell bracket 5. Four of the rubber support ribs 11 are pressed and fixed to the outer wall of the semi-circular support ring 8, while the other four rubber support ribs 11 are placed on the top of the connecting column 7, as shown in the attached diagram. Figure 6 As shown, complete the connection between the BOX assembly and the C-shell bracket 5;
[0033] Two rubber shock-absorbing rings 9 further absorb the audio vibration generated by the BOX components, the buffer ring 10 buffers the continuous vibration, and eight rubber support ribs 11 play the role of supporting, fixing and dispersing vibration. In addition, the rubber pad 6 at the bottom of the connecting post 7 absorbs the audio vibration from the connecting post 7, preventing the vibration from being transmitted to the C shell bracket 5, thereby avoiding the vibration from being transmitted to the inside of the laptop, the desktop or other devices.
[0034] In summary, this invention utilizes a multi-stage damping design with a damping pad 2 and a damping ring structure in the speaker 3. This design effectively absorbs and disperses vibrations generated by the audio box, reducing the transmission of vibrations to the laptop, desktop, or other devices. This prevents device instability or noise interference caused by vibration, effectively reduces interference from high-frequency and low-frequency vibrations on audio signal components, and avoids audio distortion. Through the action of multiple damping mechanisms, the damping effect is dynamically adjusted according to the vibration intensity, adapting to vibrations of different frequencies and intensities, providing a more precise damping effect, and meeting diverse audio playback needs.
