Abstract

The invention relates to a spherical glass sound box and a manufacturing method. The spherical glass sound box is characterized by being formed by combining a spherical glass shell, a mounting plate,a loudspeaker, a low-frequency radiator, a sound-absorbing cotton cushion and the like. High-light-transmittance glass is used, and a spherical shell is manufactured through a hot melting pressing method. Concave patterns with different sizes are uniformly distributed on the outer surface of the spherical shell, so that the consumption of materials is reduced, the heavy weight of the shell is avoided, the overall strength of the shell is ensured, and meanwhile, a gorgeous optical effect is highlighted. And the generation of standing waves in the box is inhibited by the cylindrical inner cavityand the reasonable sound absorption material and the combination of the loudspeaker and the low-frequency radiator, and the box vibration is effectively controlled by the high-density glass materialand the high-strength structural box body. Therefore, the high-quality sound playing performance of the whole box is fully guaranteed. According to the invention, the acoustic technology and the optical technology are organically combined, and a novel product with time sense is provided for people.

Description

technical field [0001] The invention relates to a spherical glass sound box and a manufacturing method thereof. More specifically, it relates to a spherical glass sound box with a high light transmittance glass material as a shell and a manufacturing method thereof. Background technique [0002] For nearly a hundred years, wooden hexahedron speakers have always been used as the mainstream form of speakers until today. Wooden speakers generally have the phenomenon of sound staining, and with time and environmental changes, they are prone to aging, deformation, and cracking. With the depletion of forest resources, especially precious wood has become a scarce material. Glass, especially glass with high light transmittance, is transparent and dazzling, and the visual effect is very shocking. With the continuous improvement of people's aesthetic requirements, speakers made of glass materials have attracted great attention. The processing of glass materials is very complicated...
