Description

Technical Field

[0001] The utility model relates to the technical field of drum shields, in particular to a transparent acrylic drum shield for sound insulation and noise reduction. Background Art

[0002] A drum shield is an auxiliary device for a drum set made of plate material. It is usually composed of multiple plates and has the function of sound insulation, noise reduction and prevention of crosstalk. In band rehearsals, performances and other scenarios, multi-track audio recording is required during recording or live performances. Due to the high volume of the drum set, the high-frequency sound of the drum set can easily be transmitted to the audio tracks of other musicians and singers, affecting the overall performance quality of the band. The use of a drum shield can effectively block the spread of drum sound, reduce the volume of the drum, and reduce noise interference to the surrounding environment, thereby obtaining cleaner decibel materials and facilitating post-production. At the same time, it can also allow other musicians to better hear the sound of their own instruments when playing, improving the overall quality of the performance. It is a commonly used auxiliary equipment in the band.

[0003] In terms of installation structure, existing drum shields are mostly connected and installed by flipping hinges to the plate structure. During installation, the hinges and the sides of the plates are fastened and installed by bolt structures. Considering the stability of the connection, multiple bolts need to be set at the connection between the sides of the plates and the hinges. During disassembly and assembly, multiple bolts need to be tightened and disassembled, which makes disassembly and assembly less convenient. In addition, when installing the hinges, due to the lack of installation limit and positioning structures, it is difficult to quickly align and position the holes during the installation process, and the installation operation is very inconvenient. For this reason, a transparent acrylic drum shield with sound insulation and noise reduction is proposed. Utility Model Content

[0028] High transparency: Acrylic material has crystal-like transparency, with a light transmittance of over 92%, allowing drummers to clearly see the drum set and surrounding environment when using the drum shield without affecting their sight.

[0029] Good processing performance: It can be made by thermoforming or machining, and can be processed into various shapes and sizes according to different needs, meeting the use requirements of different drum sets and installation needs in different scenarios;

[0030] Strong impact resistance: Compared with materials such as glass, acrylic has stronger impact resistance, which is sixteen times that of ordinary glass. It is not easy to break even if it is impacted by external forces, making it safer to use.

[0031] Light weight: The density of acrylic is only half of that of glass, which makes the acrylic drum shield lighter and easier to carry and install without placing too much burden on the drum set or performance venue;

[0032] The above characteristics make the acrylic plate 1 easy to install and process and allow the drummer to clearly see the drum set and the surrounding environment when using the drum shield without affecting the performance line of sight.

[0033] The connecting mechanism is used for splicing and installing the acrylic board 1. The connecting mechanism includes a board connecting seat 2, a connecting hinge 3 and a corner limit block 4. Figure 4 As shown, the plate connecting seat 2 is installed on the upper and lower ends of adjacent acrylic plates 1 for fixing and splicing adjacent acrylic plates 1. Figure 5As shown, in order to facilitate the alignment and installation of the acrylic plate 1, end plate grooves 9 are provided on the upper and lower sides of the plate connecting seat 2, and the end plate grooves 9 are adapted to the end sides of the acrylic plate 1. The end sides of the acrylic plate 1 are embedded and installed in the inner sides of the end plate grooves 9.
