Description

Technical Field

[0001] This utility model relates to the field of audio-visual equipment technology, and in particular to a soundproofing structure based on a home karaoke system. Background Technology

[0002] As an important part of modern leisure and entertainment, the widespread use of home karaoke in ordinary residences has made sound insulation and noise reduction an increasingly prominent technical challenge and user pain point.

[0003] Traditional home karaoke soundproofing technology generally suffers from core defects such as low-frequency resonance traps and lateral sound transmission (sound bridges). These defects often prevent soundproofing structures from effectively preventing low-frequency vibrations from spreading to neighbors, causing many unnecessary disputes and greatly limiting the actual application experience of home karaoke.

[0004] Specifically, relying solely on walls constructed with high-density materials, their inherent resonant frequencies easily fall within the sensitive frequency range of KTV music, causing a significant deterioration in sound insulation at that frequency. At the same time, structural connections that are not thoroughly decoupled, such as the rigid contact between the wall and the floor slab, provide an unobstructed sound bridge for sound vibration, rendering the main sound insulation structure virtually ineffective.

[0005] In addition, traditional ceiling sound insulation often uses simple hooks or a single sound-absorbing material, which has limited decoupling ability and is easily affected by structural characteristics, allowing airborne noise and structural vibrations from the KTV room, especially the low-frequency part, to easily propagate to the upper space, making it difficult to achieve effective sound insulation. Utility Model Content

[0006] The main purpose of this invention is to provide a soundproofing structure for home KTVs, aiming to solve the problem that the soundproofing and noise reduction effect of existing soundproofing structures is poor.

[0007] To achieve the above objectives, this utility model provides a soundproofing structure for home karaoke rooms. The soundproofing structure is installed inside a building room and includes: The ground structure includes a vibration damping layer, a sound insulation layer, and a finishing layer. The vibration damping layer is disposed on the floor of the building room, the sound insulation layer is disposed on the vibration damping layer, and the finishing layer is disposed on the sound insulation layer. The wall structure includes an air layer, a fixing layer, and a sound-absorbing layer. The fixing layer includes a keel frame, which is spaced apart on the wall of the building room to form an air layer. The sound-absorbing layer is disposed on the keel frame. A suspended ceiling structure, comprising a ceiling frame and vibration damping components, wherein the ceiling frame is movably mounted on the ceiling of the building room via the vibration damping components and maintains a dynamic seal with the walls of the building room.

[0008] Furthermore, the outer periphery of the ground structure is rounded to form a bend, and the outer end face of the bend abuts against the inner wall of the wall structure.

[0009] Furthermore, the sound insulation layer is provided with a number of absorption holes.

[0010] Furthermore, the keel frame includes several keel frames, each keel frame being provided with tenon and groove structures, and the several keel frames being spliced ​​together to form the keel frame through the tenon and groove structures.

[0011] Furthermore, the sound-absorbing layer includes sound-insulating felt, sound-absorbing cotton, and gypsum board. The sound-insulating felt is connected to the keel frame, the sound-absorbing cotton is filled inside the keel frame, and the gypsum board is connected to the sound-insulating felt.

[0012] Furthermore, the sound-absorbing layer is also fixedly disposed on the lower end face of the top frame.

[0013] Furthermore, the ceiling structure also includes a sealing strip, and the ceiling frame and sound-absorbing layer are connected to the walls of the building room through the sealing strip.

[0014] Furthermore, the vibration damping assembly includes a vibration damping seat, a vibration damping rod, and a vibration damping component. The vibration damping seat is fixedly disposed on the upper end surface of the top frame, the vibration damping rod is fixedly disposed on the top surface of the building room, and the vibration damping component is disposed inside the vibration damping seat and movably connected to the vibration damping rod.

[0015] Furthermore, the vibration damping component includes a movable component, and both the upper and lower end faces of the movable component are provided with elastic elements. The upper end face of the movable component is movably connected to the lower end face of the vibration damping rod.

[0016] Furthermore, a fixing rope is also provided on the top frame, and the free end of the fixing rope is connected to the vibration damping rod.

[0017] This invention utilizes a ground structure with a vibration-damping layer that absorbs vibration energy generated during equipment operation through elastic deformation, a sound insulation layer that blocks sound waves from propagating through the ground, and a finishing layer that reduces sound wave reflection and reverberation. In the wall structure, the keel frame is installed non-contactly to the building wall, eliminating sound bridges formed by rigid structural connections. An air layer blocks lateral sound wave transmission, and a sound-absorbing layer absorbs sound energy through porous materials. In the ceiling structure, vibration-damping components create a dynamic connection between the ceiling frame and the building ceiling, blocking vibrations from being transmitted through rigid contact. A dynamic sealing design allows for minor structural displacement while maintaining airtightness, preventing airborne sound leakage. The ground, walls, and ceiling structures work together to form a three-dimensional sound barrier, gradually attenuating sound and vibration energy in different directions through a combination of elastic support, air isolation, and dynamic decoupling.

[0025] Example: Please refer to the attached document as well. Figures 1 to 7 This embodiment provides a soundproofing structure for a home karaoke room. The soundproofing structure is installed inside room 1 of a building and includes: Ground structure 2, the ground structure 2 includes a vibration damping layer 21, a sound insulation layer 22 and a finishing layer 23, the vibration damping layer 21 is disposed on the ground of the building room 1, the sound insulation layer 22 is disposed on the vibration damping layer 21, and the finishing layer 23 is disposed on the sound insulation layer 22; The wall structure 3 includes an air layer 33, a fixing layer 34, and a sound-absorbing layer 35. The fixing layer 34 includes a keel frame 31, which is spaced apart on the wall of the building room 1 to form an air layer 33. The sound-absorbing layer 35 is disposed on the keel frame 31. The ceiling structure 4 includes a ceiling frame 47 and a vibration damping component 40. The ceiling frame 47 is movably mounted on the ceiling of the building room 1 via the vibration damping component 40 and maintains a dynamic seal with the wall of the building room 1.

[0026] It should be noted that in existing technologies, soundproofing structures for home KTVs generally suffer from problems such as low-frequency resonance transmission, lateral sound bridge propagation, and ceiling vibration transmission. Traditional methods rely on high-density wall material stacking, but the inherent resonant frequency of the wall easily overlaps with the sensitive frequency bands of KTV music, leading to a deterioration in soundproofing. Rigid structural connections form sound bridges, causing vibrations to propagate along the contact surface between the wall and the floor slab. Ceiling structures using simple hooks or single sound-absorbing materials have insufficient decoupling capabilities, making it difficult to block the transmission of airborne sound and structural vibrations to the upper floors. In ordinary residences, low-frequency vibrations in KTV rooms are transmitted to the main building through the floor, lateral sound waves diffuse through gaps in the wall connections, and ceiling vibrations cause noise in the upper-floor space, resulting in soundproofing failure.

[0027] It should also be noted that, based on the above problems, this embodiment provides a sound insulation structure for a home KTV. In the ground structure 2, the vibration damping layer 21 absorbs the vibration energy generated during equipment operation through elastic deformation, the sound insulation layer 22 blocks sound waves from propagating through the ground, and the finishing layer 23 reduces sound wave reflection and reverberation. In the wall structure 3, the keel frame 31 is installed non-contactly with the building wall, eliminating the sound bridge formed by the rigid connection of the structure. The air layer 33 blocks the transmission of lateral sound waves, and the sound-absorbing layer 35 absorbs sound energy through porous materials. In the ceiling structure 4, the vibration damping component 40 makes the ceiling frame 47 dynamically connected to the building ceiling, blocking vibration from being transmitted through rigid contact. The dynamic sealing design allows for slight structural displacement while maintaining airtightness, preventing airborne sound leakage. The ground, walls, and ceiling structure 4 work together to form a three-dimensional sound barrier. Through a combination of elastic support, air isolation, and dynamic decoupling, sound vibration energy in different directions is attenuated step by step.

[0028] Through the above technical solutions, this embodiment effectively blocks the transmission of low-frequency vibrations during the operation of a home KTV through the building structure, eliminates the sound bridge effect formed by the rigid connection of the wall through lateral sound waves, prevents ceiling vibrations from being transmitted to the upper space, and reduces the dual transmission of vibration and airborne sound by the combination of elastic vibration reduction and high-density sound insulation of the ground structure 2. The air layer 33 and the sound-absorbing layer 35 of the wall work together to consume lateral sound energy, and the dynamic decoupling design of the ceiling blocks the vertical vibration path. This embodiment achieves three-dimensional sound insulation in ordinary residential environments, solving the technical defects of traditional methods such as sensitivity of the sound insulation structure to the resonant frequency band, significant sound bridge effect, and serious sound transmission from the ceiling.

[0029] In some embodiments, the vibration damping layer 21 refers to an elastic material layer laid on the building floor, which can be implemented using rubber pads, to absorb equipment vibration energy and reduce structural vibration transmission.

[0030] In some embodiments, the sound insulation layer 22 refers to a high-density material layer covering the vibration damping layer 21, which can be implemented using gypsum board 38 or composite sound insulation board, and is used to block the propagation path of airborne sound.

[0031] In some embodiments, the finishing layer 23 refers to a decorative layer located on the surface of the sound insulation layer 22, which may be made of wood flooring or ceramic tile, and is used to avoid sound wave reflection from hard surfaces.

[0032] In some embodiments, the air layer 33 refers to the gap between the keel frame 31 and the building wall, specifically maintaining a distance to eliminate the sound bridging effect caused by rigid contact.

[0033] In this embodiment, the outer periphery of the ground structure 2 is rounded to form a bent portion 24, and the outer side of the end face of the bent portion 24 abuts against the inner wall of the wall structure 3.

[0034] Understandably, the rounded corner bend 24 at the edge of the ground structure 2 reconstructs the contact interface between the ground and the wall through a curved transition, causing the vibration wave to deflect when it reaches the connection. The surface contact design between the end face of the bend 24 and the wall increases the contact area, reducing the pressure per unit area to 30%-50% of that of a traditional right-angle connection. The contact surface undergoes elastic deformation when impacted by sound waves, resulting in mechanical impedance mismatch.

[0035] In this embodiment, the sound insulation layer 22 is provided with a plurality of absorption holes 25. When sound waves enter the sound insulation layer 22 with absorption holes 25, the abrupt interface formed at the edge of the holes will induce a scattering effect of the sound waves. For mid-to-low frequency sound waves, the hole structure can form a local Helmholtz resonant cavity. The sound waves resonate and rub against the air column inside the holes, thereby converting sound energy. At the same time, the interval between the holes forms a phase difference of the sound waves, and the sound waves reflected from adjacent holes will produce destructive interference when superimposed.

[0036] In this embodiment, the keel frame 31 includes several keel skeletons 32, each equipped with a tenon and groove structure. These keel skeletons 32 are joined together using the tenon and groove structures to form the keel frame 31. The keel skeletons 32 are joined by inserting tenons into grooves, with a small gap maintained between the tenons and grooves, allowing adjacent keel skeletons 32 to slide relative to each other at the micrometer level under vibration. Compared to existing technologies, traditional keel frames 31 use rigid connections via welding or bolts, where adjacent components form sound bridges leading to direct transmission of vibration energy. This solution, however, uses a non-rigid connection method with tenon and groove joints, which, while ensuring structural stability, utilizes contact surface friction and local deformation to dissipate vibration energy and effectively cut off lateral sound transmission paths.

[0037] In this embodiment, the sound-absorbing layer 35 includes a sound-insulating felt 36, a sound-absorbing cotton 37, and a gypsum board 38. The sound-insulating felt 36 is connected to the keel frame 31, the sound-absorbing cotton 37 is filled inside the keel frame 31, and the gypsum board 38 is connected to the sound-insulating felt 36.

[0038] Understandably, the sound insulation felt 36 is directly fixed to the surface of the keel frame 31 to form a continuous covering layer. The high density of the material itself blocks the transmission path of mid-to-high frequency sound waves along the frame structure. The sound-absorbing cotton 37 completely occupies the cavity formed by the keel frame 31 through compression filling. The tortuous pore channels within the porous material extend the sound wave propagation path, allowing low-frequency sound waves to be gradually absorbed during repeated reflections. The gypsum board 38 covers the outside of the sound insulation felt 36, forming a rigid constraint layer. This increases the overall structural mass and reduces the resonant frequency. Simultaneously, it forms an elastic sandwich structure with the sound insulation felt 36, causing residual sound waves penetrating the gypsum board 38 to cancel each other out in the sandwich structure.

[0039] In this embodiment, the sound-absorbing layer 35 is also fixedly disposed on the lower end face of the ceiling frame 47. The sound-absorbing layer 35 is installed on the lower end face of the ceiling frame 47 by a fixed connection, forming a continuous sound barrier facing the indoor sound field. The ceiling frame 47, as the supporting frame of the suspended ceiling, directly bears the impact of indoor airborne sound waves on its lower end face. The sound-absorbing felt 36 in the sound-absorbing layer 35 and the gypsum board 38 are rigidly fixed to form a multi-layer damping structure, effectively attenuating sound wave energy.

[0040] In this embodiment, the ceiling structure 4 further includes a sealing strip, and the ceiling frame 47 and the sound-absorbing layer 35 are connected to the wall of the building room 1 through the sealing strip.

[0041] It should be noted that the ceiling frame 47 and the sound-absorbing layer 35 form an elastic contact with the wall surface through a sealing strip. When sound waves act on the ceiling structure 4, the sealing strip absorbs vibration energy through its own deformation, blocking the propagation path of airborne sound waves along the connection gap. The continuous arrangement of the sealing strips forms a closed vibration isolation barrier, eliminating the sound bridge effect caused by traditional rigid connections. When the structure is affected by thermal expansion and contraction or sound pressure fluctuations, the elastic characteristics of the sealing strip can adaptively adjust the interface contact pressure to maintain a dynamic sealing state.

[0042] In this embodiment, the vibration damping assembly 40 includes a vibration damping seat 41, a vibration damping rod 42, and a vibration damping element 43. The vibration damping seat 41 is fixedly disposed on the upper end surface of the top frame 47, the vibration damping rod 42 is fixedly disposed on the top surface of the building room 1, and the vibration damping element 43 is disposed in the vibration damping seat 41 and is movably connected to the vibration damping rod 42.

[0043] Understandably, the vibration damping seat 41 and the top frame 47 are rigidly connected to form an integral support structure. The vibration damping rod 42 is fixed to the building's roof surface, forming a vibration transmission path. The vibration damping element 43 is constrained inside the vibration damping seat 41, and its movable connection end forms a non-rigid contact with the vibration damping rod 42. When the building's roof surface vibrates, the vibration is transmitted to the vibration damping element 43 through the vibration damping rod 42. The elastic element 45 undergoes compressive deformation in the vertical direction, converting the vibration energy into elastic potential energy. At the same time, the displacement space of the movable element 44 allows the top frame 47 to produce slight oscillations, disrupting the continuous propagation path of the vibration wave in the structure. Through the synergistic effect of elastic buffering and mechanical damping, multi-stage attenuation of vibration energy is achieved.

[0044] In this embodiment, the vibration damping component 43 includes a movable component 44, with elastic elements 45 on both its upper and lower end faces. The upper end face of the movable component 44 is movably connected to the lower end face of the vibration damping rod 42. The movable component 44 forms a bidirectional buffer structure through the symmetrically distributed elastic elements 45 at its upper and lower ends. When the ceiling structure 4 is subjected to low-frequency vibration, the elastic elements 45 deform alternately in compression and tension, converting vibration energy into elastic potential energy and gradually dissipating it. The movable connection between the movable component 44 and the vibration damping rod 42 causes dynamic displacement in the vertical direction, cutting off the sound bridge path formed by rigid contact. The synergistic effect of the upper and lower elastic elements 45 can simultaneously attenuate vibration waves from the ceiling frame 47 and the vibration damping rod 42, especially forming a multi-level damping effect against the multi-directional impact force generated by low-frequency vibration.

[0045] In this embodiment, a fixing rope 46 is also provided on the top frame 47, and the free end of the fixing rope 46 is connected to the vibration damping rod 42.

[0046] It should be noted that one end of the fixing rope 46 is fixed to the top frame 47, while the other end is connected to the vibration damping rod 42 in a free state. When the ceiling structure 4 is subjected to low-frequency vibration, the fixing rope 46 dynamically constrains the vibration amplitude of the vibration damping rod 42 through its own flexible deformation, while allowing the vibration damping component 40 to undergo vertical displacement compensation. The vibration energy is partially absorbed by the tensile deformation of the fixing rope 46, thereby blocking the rigid transmission path of the vibration wave along the vibration damping rod 42 to the building roof. The flexible connection between the top frame 47 and the vibration damping rod 42 avoids the sound bridge effect formed by traditional rigid suspension rods, while preserving the displacement freedom of the vibration damping component 40 during vertical vibration, preventing secondary vibration transmission caused by excessive constraint.

[0047] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
