Description

Technical Field

[0001] This utility model relates to the field of sound-generating products, and in particular to a housing assembly and electronic product. Background Technology

[0002] Most electronic products that produce sound typically use built-in speakers as the sound source. In a typical hardware structure, the speaker unit is fixed inside the main housing of the device, and the front sound outlet is usually covered with a layer of metal stamped iron mesh to protect the internal speaker unit and also serve a decorative purpose.

[0003] However, when a loudspeaker is operating at high power, especially in the mid-to-low frequency range, the vibrations it generates are transmitted throughout the entire device via the air and structural components. When the sound waves emitted by the loudspeaker, especially those at specific frequencies (such as low-frequency resonant frequencies), couple with the inherent frequencies of the metal mesh-shell composite structure, it causes the metal mesh to vibrate. This manifests as unpleasant "vibration" or "noise" (i.e., abnormal mechanical noise), severely interfering with the original electroacoustic signal emitted by the loudspeaker. Superimposed on the normal sound waves, this results in a significant decrease in the clarity and purity of the final output sound, seriously affecting the listening experience and sound quality evaluation of the product.

[0014] In existing technology, when a speaker emits sound waves, it causes the metal mesh to vibrate, which severely interferes with the original electroacoustic signal emitted by the speaker. This signal is superimposed on the normal sound wave, resulting in a significant decrease in the clarity and purity of the final output sound, which seriously affects the auditory experience and sound quality evaluation of the product.

[0015] This utility model proposes a housing assembly.

[0016] Please see Figures 1 to 4 In one embodiment of the present invention, the housing assembly includes: a protective net 200 on the housing body 100 and a vibration damping member 300, wherein the protective net 200 is disposed on one side of the housing body 100 and the edge of the protective net 200 is fixedly connected to the housing body 100; the vibration damping member 300 protrudes from the housing body 100 and abuts against the protective net 200.

[0017] The outer shell 100 is typically made of plastic, such as ABS or PC / ABS, through injection molding. The protective net 200 is fixedly connected to the outer shell 100 by clips or screws. In this embodiment, the edge of the protective net 200 is connected to the outer shell 100 by high-frequency heat fusion. The damping element 300 is fixed to the outer shell 100 and protrudes, abutting against the side of the protective net 200 facing the outer shell 100. The damping element 300 has a certain elasticity and abuts against the protective net 200, causing it to be compressed to ensure the presence of preload, achieve a good damping effect, and reduce the vibration of the protective net 200. The shape of the damping element 300 is not limited to ring or dot, but can also be radial strips, mesh, etc. Its material can be silicone, or any material with good damping properties such as TPE, foam, or rubber. In addition, the damping element 300 can also be a vibration damping component.

[0018] This utility model's technical solution employs a vibration damping component 300 positioned between the outer casing 100 and the protective mesh 200 to limit the vibration of the protective mesh 200. Specifically, the vibration damping component 300 is fixedly mounted on the outer casing 100 and protrudes, with the protruding portion contacting the protective mesh 200, thereby reducing the vibration of the protective mesh 200. The vibration damping component 300 directly abuts against the inner surface of the protective mesh 200. When the electronic product used in this casing assembly is operating, its vibration is transmitted to the protective mesh 200. The vibration damping component 300 effectively constrains and suppresses the vibration amplitude of the protective mesh 200, fundamentally disrupting the resonance conditions that generate "vibration" or "noise," reducing abnormal noise caused by parasitic vibration of the protective mesh 200, thus ensuring the purity of sound playback and improving the product's sound quality.

[0019] In one embodiment, the outer shell body 100 has a mounting groove 110, one end of the vibration damping member 300 is disposed in the mounting groove 110, and the other end protrudes from the mounting groove 110 and abuts against the protective net 200.

[0020] Specifically, a mounting groove 110 is formed on the side of the outer shell 100 facing the protective net 200. The mounting groove 110 serves to position and install the vibration damper 300. During assembly, one end of the vibration damper 300 is inserted into the mounting groove 110, and the other end extends out of the mounting groove 110 to abut against the protective net 200, simplifying the assembly process and improving assembly efficiency. Furthermore, the vibration damper 300 and the mounting groove 110 are interference-fitted, and adhesive can also be applied inside the mounting groove 110 to enhance the installation strength of the vibration damper 300. In addition, it should be noted that the length of the vibration damper 300 extending out of the mounting groove 110 is set according to the contour of the protective net 200, so that the top of the vibration damper 300 can abut against the protective net 200, avoiding uneven support caused by height differences of the vibration damper 300.

[0021] refer to Figure 3 and Figure 4 As shown, in one embodiment, the bottom surface of the mounting groove 110 and the vibration damper 300 are provided with a positioning post 120 and a positioning groove 310, respectively, and the positioning post 120 is inserted into the positioning groove 310.

[0022] Taking one embodiment where the positioning post 120 is located on the bottom surface of the mounting groove 110 as an example, in the specific implementation process, the positioning post 120 protrudes from the bottom surface of the groove, and the end face of the damping member 300 located in the mounting groove 110 is provided with a positioning groove 310. The positioning groove 310 is adapted to be inserted into the positioning post 120, and the part of the damping member 300 with the mounting groove 110 is accommodated in the space between the positioning post 120 and the inner wall of the mounting groove 110.

[0023] In one embodiment, one of the mounting groove 110 and the vibration damper 300 is provided with a limiting part 130, and the other is provided with a recessed part 320, with the limiting part 130 inserted into the recessed part 320.

[0024] Taking one embodiment where the mounting groove 110 has a limiting portion 130 and the vibration damper 300 has a recessed portion 320 as an example, in specific implementation, the limiting portion 130 protrudes from the inner wall of the mounting groove 110, and one end of the vibration damper 300 is adapted to have the recessed portion 320. During assembly, the limiting portion 130 is accommodated in the recessed portion 320, which plays a limiting role in the circumferential direction of the vibration damper 300. Further, the limiting portion 130 is connected to the inner wall of the mounting groove 110 and the outer wall of the positioning post 120 respectively. The limiting portion 130 is configured as a notch of the vibration damper 300, communicates with the mounting groove 110, and extends to the outer peripheral wall of the vibration damper 300.

[0025] In practical implementation, the vibration damper 300 is made of soft rubber. Specifically, this refers to polymer materials with low hardness, good elastic deformation capacity, and high internal molecular damping characteristics. Its core feature is its ability to absorb mechanical vibrations through its own elastic deformation, thereby achieving vibration reduction. Specific materials include, but are not limited to: silicone, rubber, TPE, TPU, etc. The soft rubber material generates a continuous and gentle rebound force after being compressed, ensuring that the vibration damper 300 and the inner surface of the protective net 200 maintain a stable and tight contact, preventing failure due to prolonged pressure or minor displacement. Elastic support is more adaptable to vibrations of different frequencies and amplitudes compared to rigid support.

[0026] In one embodiment, the vibration damper 300 is made of a light-transmitting material, and the color of the vibration damper 300 in the non-light-transmitting state matches the color of the protective net 200.

[0027] It should be noted that "translucent material" refers to material that allows visible light to pass through. When there is internal lighting in the product, the light can pass through the damper 300 and shine towards the protective net 200 and the outside of the product, thus making the damper 300 invisible. In specific implementation, the material color of the damper 300 is similar to the color of the protective net 200, or the damper 300 is coated with a coating whose color matches the protective net 200. For example, when the protective net 200 is black, the damper 300 can be brown or tan, or the color difference between the protective net 200 and the damper 300 can be less than 2. Thus, the color of the damper 300 in its non-translucent state is similar to the color of the protective net 200. This makes it impossible to distinguish the boundary between the damper 300 and the protective net 200 when looking into the product from the outside (the side of the protective net 200 away from the outer shell 100) when there is no internal lighting, thus making the internal damper 300 invisible and achieving a "hidden" effect.

[0028] In one embodiment, multiple vibration damping elements 300 are provided, and these multiple vibration damping elements 300 are spaced apart on the outer shell body 100. It is understood that the mounting grooves 110 are correspondingly provided with one vibration damping element 300. In specific implementation, the multiple vibration damping elements 300 can be distributed in a regular array on the outer shell body 100, or they can be distributed according to the specific structure of the outer shell body 100 and the protective net 200, as long as they can buffer the vibration of the protective net 200. By setting multiple spaced vibration damping elements 300, it is equivalent to establishing multiple "damping support points" on the back of the protective net 200, improving the overall structural stiffness of the protective net 200, thereby achieving a more comprehensive and uniform vibration damping effect and eliminating local noise.

[0029] Furthermore, the outer casing 100 is also provided with inspection holes 140, and vibration damping elements 300 are provided between the inspection holes 140. (Reference) Figure 1As shown, the outer casing 100 is provided with multiple inspection holes 140, such as two inspection holes 140 with larger inner diameters and two inspection holes 140 with smaller inner diameters. The inspection holes 140 are used to inspect the connection between the protective net 200 and the outer casing 100. The part between the inspection holes 140 is a weak point. By setting vibration damping components 300 in this part, the connection strength between the outer casing 100 and the protective net 200 is improved, ensuring the vibration damping effect.

[0030] In one embodiment, the protective mesh 200 is configured as a metal mesh, with its edges heat-fused to the outer casing 100. In specific implementations, the metal mesh is preferably made of stainless steel, galvanized steel, or aluminum alloy, manufactured through stamping, stretching, or weaving processes, possessing sufficient strength to provide protective functionality and ensuring efficient sound wave transmission. It should be noted that the non-edge portion of the protective mesh 200 has a certain gap space with the support of the outer casing 100, where the vibration damping element 300 is located and abuts against and supports the protective mesh 200. Furthermore, the abutment between the vibration damping element 300 and the protective mesh 200 occurs after assembly, causing the vibration damping element 300 to be slightly compressed, thereby providing additional elastic support to the central area of ​​the protective mesh 200. The vibration damping element 300 provides a reliable support point for the central part of the protective mesh 200, forming a multi-point support structure, significantly reducing the "vibration" caused by the metal mesh vibration and improving the purity of the product's sound output.

[0031] This utility model also proposes an electronic product, which includes a housing assembly. The specific structure of the housing assembly is as described in the above embodiments. Since this electronic product adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

Any equivalent structural transformations made based on the inventive concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
