Description

Technical Field

[0001] This invention relates to the field of sound insulation and noise reduction technology, and specifically to a soundproof room. Background Technology

[0002] A soundproof room, also known as a quiet room, soundproof room, or noise chamber, is a sound insulation testing device designed for product manufacturing workshops with testing requirements. It is also called a sound insulation test room and is widely used in the testing of various electronic products, such as loudspeakers, microphones, small motors, household appliances, and automobiles.

[0003] In practical applications, existing soundproof rooms typically use multi-layered composite panels to provide sound insulation for the indoor space. However, since the sound insulation function is achieved by stacking the properties and thickness of the materials, the overall weight and cost of the soundproof room continue to increase with the requirements of sound insulation performance. Furthermore, since the soundproof room is made of prefabricated panels that are installed and formed later, the high weight of the room material also increases the difficulty of later installation and maintenance, thus limiting the overall economy and practicality. Summary of the Invention

[0004] In view of the above-mentioned technical problems in the prior art, a soundproof room is provided to solve the problem that the soundproof structure of the existing soundproof room, which achieves sound insulation function by stacking composite materials, is not economical and practical.

[0005] The objectives and effects of this invention are achieved by the following specific technical means:

[0006] A soundproof chamber includes a base plate frame, which is a rectangular hollow frame structure. Side sealing plates are fixed on all sides of the base plate frame, and a chamber door is reserved in one of the side sealing plates. A partition frame and a filling plate are embedded in the side sealing plate, and the partition frame and the filling plate are fitted and matched. An inner lining plate is fixed between the partition frame and the base plate frame.

[0007] The base plate frame is provided with a top plate and a bottom plate seat at the top and bottom, respectively, and a suspension is formed by the protrusion of the middle of the top plate. A tenon head is inserted into one end of the suspension near the base plate frame. A T-shaped suspension plate is horizontally fixed to the top inner side of the base plate frame, and the tenon head is connected to the T-shaped suspension plate in a tenon-tenon joint.

[0008] Two empty compartments are symmetrically arranged on both sides of the suspension. A pressure plate frame is fixed between the empty compartment and the top plate, and the pressure plate frame is interconnected with the empty compartment. A passage opening is opened on the side of the pressure plate frame.

[0009] A further preferred embodiment: the partition frame and the filling plate are a matching grooved frame structure and strip sound insulation material, and a lateral airflow groove is formed between the filling plate and the partition frame.

[0010] A further preferred embodiment: the filling plate includes several horizontally arranged strip-shaped inner linings, the edges of which are fitted with the partition frame are filled with felt, and adhesive strips are fixedly provided between the strip-shaped inner linings.

[0011] A further preferred embodiment: a fastener is fixed between the corner of the top plate and the side sealing plate.

[0012] A further preferred embodiment: the top plate covers the empty compartment box and the connection between the top plate and the empty compartment box is laterally sealed by a pressure plate frame, and the two sides of the pressure plate frame are respectively connected to the inner lining plate.

[0013] A further preferred embodiment: the inner lining is a strip-shaped fiber lining, and a strip-shaped window is formed at the seam where the inner lining connects to the partition frame.

[0014] A further preferred embodiment: a wiring box is inserted into one end of the base plate, the wiring box including a wire reel, a cable terminal box and a sealing tube, the sealing tube being disposed between the wire reel and the cable terminal box, and the wire reel opening passing through the outside of the base plate, the cable terminal box passing through to the inside of the base plate frame.

[0015] A further preferred embodiment: a hollow base is fixed at the connection end between the base plate and the base plate frame, a cable tray is connected between the inner side of the base and the cable terminal box, and a connector is provided through the cable tray to the surface of the base.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This type of soundproof chamber uses a frame structure with a base plate as the main body as the soundproof chamber structure. It is sealed by side sealing plates, top plate, and bottom plate seats. Based on the spliced ​​assembly structure, partition frames and filling plates are arranged between the side sealing plates and the base plate to ensure its airtightness and sound insulation by using the interlocking structure and the material properties of the filling plates. The empty box and pressure plate frame arranged in the top plate connect the cavity and gap between the top plate and the side sealing plates to separate the internal space of the soundproof chamber and reduce the sound transmission between the indoor and outdoor through the airflow. This soundproof chamber structure can ensure the sound insulation effect while avoiding the problems of high cost, poor economy and large overall weight of using stacked composite panels.

Detailed Implementation

[0025] Please see Figure 1-6 The embodiments of the present invention will be further described below;

[0026] A soundproof chamber includes a base plate frame 1, which is a rectangular hollow frame structure. Side sealing plates 3 are fixed on all sides of the base plate frame 1, and a door is reserved in one of the side sealing plates 3. A partition frame 7 and a filling plate 8 are embedded in the side sealing plate 3, and the partition frame 7 and the filling plate 8 are fitted and matched. An inner lining plate 6 is fixed between the partition frame 7 and the base plate frame 1.

[0027] The top plate 2 and the bottom plate seat 4 are arranged opposite to each other at the top and bottom of the substrate frame 1, and a suspension 13 is formed by protruding in the middle of the top plate 2. A tenon head 21 is inserted into one end of the suspension 13 near the substrate frame 1. A T-shaped suspension plate 22 is horizontally fixed on the top inner side of the substrate frame 1, and the tenon head 21 is tenon-tenon connected to the T-shaped suspension plate 22.

[0028] Two empty compartment boxes 11 are symmetrically arranged on both sides of the suspension 13. A pressure plate frame 12 is fixed between the empty compartment box 11 and the top plate 2. The pressure plate frame 12 is interconnected with the empty compartment box 11, and a passage opening is opened on the side of the pressure plate frame 12.

[0029] Compared to existing chamber structures constructed primarily of composite soundproof panels, this soundproof chamber uses a hollow base frame 1 and suspension 13 as its frame structure. The top plate 2, side sealing plates 3, and bottom plate 4 seal the panel structure, significantly reducing the overall weight of the chamber. Since a completely vacuum seal is difficult to achieve with a spliced ​​assembly structure compared to a solid structure, considering the soundproofing performance of this chamber, a fitted and assembled filling plate 8 and partition frame 7 serve as the soundproofing structure inside the inner lining plate 6. Furthermore, to prevent airflow in the assembly gaps from affecting the soundproofing performance, a hollow... The passage between the box 11 and the pressure plate frame 12 serves as a communication channel with the space inside the side sealing plate 3. The airflow indirectly reduces noise by blocking the internal partition frame 7 and the filling plate 8. While using the side sealing plate to provide sound insulation for the indoor space, the solid filling plate 8 and the partition frame 7 are combined to isolate the internal airflow and isolate the transmission of low-frequency noise. Thus, this two-way isolation can simultaneously insulate the indoor space and the internal space of the chamber. While ensuring the overall soundproof performance of the soundproof chamber, it avoids the problems of high cost and heavy weight that exist in the method of using stacked composite panels for sound insulation.

[0030] Specifically, the partition frame 7 and the filling plate 8 are a matching grooved frame structure and strip sound insulation material. A side-opening airflow groove is formed between the filling plate 8 and the partition frame 7. The side-opening airflow groove is used to connect the door panel structure enclosed at the front and rear of the chamber and the inner space on the other side. The interconnected channel structure guides the airflow through the inner space between the partition frame 7 and the inner lining plate 6 to ensure the sound insulation performance of the filling plate 8.

[0031] Specifically, the filling plate 8 includes several horizontally arranged strip-shaped inner liners 14. The edges of the strip-shaped inner liners 14 that fit into the partition frame 7 are filled with felt, and adhesive strips 9 are fixedly installed between the strip-shaped inner liners 14. The felt material is used to fill the seams to ensure the sealing performance of the combined structure of the filling plate 8 and the partition frame 7, that is, to ensure the sound insulation effect. The adhesive strips 9 connected between the strip-shaped inner liners 14 are used to assemble the strip-shaped inner liners 14 into shape.

[0032] Specifically, a fastener 10 is fixed between the corner of the top plate 2 and the side sealing plate 3. The fastener 10 is used to combine the top plate 2 and the side sealing plate 3, and further connect and fix the base plate frame 1 with the top plate 2 and the side sealing plate 3 to improve the structural strength.

[0033] Specifically, the top plate 2 covers the empty compartment box 11 and the connection between the top plate 2 and the empty compartment box 11 is laterally sealed by the pressure plate frame 12. The two sides of the pressure plate frame 12 are connected to the inner lining plate 6 respectively. The covering structure ensures the sealing of the combination of the top plate 2, the empty compartment box 11 and the pressure plate frame 12. The connection channel between the pressure plate frame 12 and the inner lining plate 6 is used to connect the sound insulation space of the side sealing plate 3.

[0034] Specifically, the inner lining plate 6 is a strip-shaped fiber inner lining plate. A strip-shaped window is formed at the edge seam where the inner lining plate 6 connects with the partition frame 7. The strip-shaped window serves as a guiding airflow channel. Together with the filling plate 8 structure formed by the strip-shaped inner lining 14, it adapts to the channel direction between the inner lining plate 6 and the partition frame 7.

[0035] Specifically, a wiring box 5 is plugged into one end of the base plate 4. The wiring box 5 includes a wire reel 15, a cable terminal box 16, and a sealing tube 17. The sealing tube 17 is disposed between the wire reel 15 and the cable terminal box 16, and the opening of the wire reel 15 passes through the outside of the base plate 4. The cable terminal box 16 extends to the inside of the base plate frame 1. Figure 4 As shown, considering that traditional open-type external wiring is prone to sound transmission through the wire channel, this soundproof chamber further uses a sealing roller 17 and a wire spool 15 to seal the wiring terminals, and works in conjunction with the docking of the wiring terminal box 16 and the base plate 4 to meet the wiring requirements of the room while ensuring soundproof performance.

[0036] Specifically, a hollow base liner 18 is fixed at the connection end between the base plate 4 and the base plate frame 1. A cable tray 20 is connected between the inner side of the base liner 18 and the cable terminal box 16. A connector 19 is provided through the cable tray 20 to the surface of the base liner 18. Based on the above, the cable routing is facilitated by routing the cable inside the cable tray 20 in the base liner 18. The sealing of the connector structure is further improved by using the plug-in sealed connector 19 to ensure the sound insulation performance of the soundproof chamber.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
