[0024] See also Figure 1-7 The utility model provides a Peking opera percussion music cage, comprising:

[0025] Hollow structure 1: The back of the music cage adopts hollow structure 1, which allows the music cage to form acoustic coupling with the space behind the stage orchestra pit, effectively absorbing sound energy, reducing internal standing wave reflection sound, and thus improving sound quality.

[0026] The music cage is equipped with two sliding, multi-linked doors (two linked doors) on both sides. The amount of sound leakage from percussion instruments is controlled by adjusting the opening degree of each linked door. The doors are foldable, adding internal non-parallel reflective surfaces to further optimize sound wave scattering.

[0027] Acrylic plate or glass 3: The front of the music cage is equipped with a transparent acrylic plate or glass 3, which not only protects the instruments from damage but also does not affect the audience's viewing of the percussionists. Specifically, 10 mm acrylic plate or glass 3 can be used to ensure safety and stability.

[0028] The music cage consists of a bottom panel 4 and a top panel 5, connected to either panel 4 or 5 by a pressure strip 6 on either side. The pressure strip 6 is a profiled structure and slots into the panel edges with a mortise and tenon joint to enhance overall stability. The bottom and top panels 4 and 5 are constructed of 38mm aluminum alloy sandwich composite wall panels covered with a polymer damping material. A custom nylon carpet is also placed on the bottom panel 4, providing complete coverage and excellent sound absorption. The sound-absorbing panels within the music cage are made of environmentally friendly, odorless Velcro and comply with European RoHS standards.

[0029] The support column 10 and the pressure strip 6 are provided with slots at the front and rear ends for fixing the support column 10 and enhancing the structural strength of the music cage.

[0030] Multi-linked door 2 track system, the sliding multi-linked door 2 adopts a four-linked door structure and is equipped with an upper and lower track system. The upper track is fixed to the top plate 5 and connected to the pressure strip 6, and the lower track is fixed to the bottom plate 4 and connected to the pressure strip 6. Both are connected by screws to ensure smooth operation of the door.

[0031] Portable handle 7 and roller 9: An L-shaped handle 7 and roller 9 are installed at the bottom of the music cage bottom plate 4, which makes it easy to move and position the music cage and improves the flexibility of use.

[0033] This design of Peking Opera percussion cage aims to provide a more harmonious and professional music accompaniment environment for modern Peking Opera performances through sophisticated acoustic design and structural optimization.

[0034] The dismantling steps of the present invention are as follows: S1. Remove the multi-link doors 2 on both sides; S2. Remove the moldings 6 on both sides of the top plate 5; S3. Remove the top plate 5 and the internal sound-absorbing material; S4. Remove the front acrylic plate or glass 3; S5. Remove the moldings 6 on both sides of the bottom plate 4; S6. Remove the bottom plate 4 and the floor carpet.

[0035] It is worth noting that the present invention has the following technical features:

[0036] Connection between the pressure strip 6 and the bottom plate 4: The pressure strip 6 adopts a profile design and is tightly connected to the bottom edge of the bottom plate 4 through a mortise and tenon structure to ensure the stability and detachability of the structure.

[0037] Connecting the bottom and top panels 4, 5, and the front acrylic panel or glass 3: An acrylic panel or glass 3 is placed between the bottom and top panels 4, with an aluminum profile with grooves placed above and below. The grooves are the same width as the thickness of the acrylic panel or glass 3, effectively fitting the acrylic panel or glass 3 and ensuring a secure fit between the top and bottom panels 5 and the bottom panel 4.

[0038] Connecting the Multi-Link Door 2 to the Holding Strip 6: The Multi-Link Door 2 utilizes an upper and lower track system. The upper track is secured to the holding strip 6 on the top plate 5 with screws, while the lower track is secured to the holding strip on the bottom plate, also with screws. The Multi-Link Door 2 slides between the upper and lower tracks, ensuring smooth movement.

[0039] Structure of the Multi-Link Door 2: The four-link door is a sliding door design, allowing the door body to be linked and pulled from either side, allowing for flexible adjustment of the opening degree to meet different usage requirements. The Multi-Link Door 2 also has a folding design. Adjusting the opening degree adjusts the ratio of sound insulation to sound transmission. Furthermore, the modular structure is more manufacturable and practical, and the Multi-Link Door 2 on both sides features adjustable features. Fully open, the sound insulation is approximately 6dB, while fully closed, the sound insulation is approximately 15dB. Sound control is achieved by controlling the opening degree of the four-link door.

[0040] The cage's mobility is enhanced by a handle 7 welded to its base and four universal rollers 9 (with brakes), allowing for easy movement and stopping. Four adjustable support legs ensure stability even on uneven surfaces. The design was inspired by a conductor's podium, as both require excellent mobility. This design significantly improves efficiency during transport and on-stage movement.

[0041] The open hollow structure 1 on the back uses the "coupled space" principle to form a sound-absorbing structure with the stage. On the one hand, it ensures good loudness and direct sound effects on the stage. On the other hand, it provides sound energy dissipation for the performers in the music cage to achieve a sound absorption effect, and once again, it achieves an auditory experience simulation similar to the diffraction of the end door for the sound energy propagation of percussion instruments in the audience area.

[0042] High light transmittance, with three sides using extremely narrow frames and high light transmittance acrylic panels or glass 3, which will not affect the musicians' performance and communication as much as possible, ensuring the overall beauty of the stage.
