AI Technical Summary

⚠Technical Problem

In existing loudspeaker housing structure designs, the housing material composition method and the spatial form design of the loudspeaker channel are independent of each other, making it difficult to form a composite material layered structure, which limits the ability of loudspeaker structure to be constructed collaboratively in spatial form design.

⚗Method used

The amplifier employs a composite material structure consisting of a celadon rigid layer, a bamboo composite transition layer, and a bamboo woven diffusion layer. Through multiple rounds of iterative adjustments using a zoned design and an acoustic structural coupling model, the thickness, fiber laying angle, density, and opening distribution of the amplifier shell are optimized to achieve a layered structure that matches the sound amplification channel path.

🎯Benefits of technology

The composite material layered structure was collaboratively constructed in the spatial morphology design of the loudspeaker shell, which improved the acoustic performance and overall stability of the loudspeaker.

Abstract

This invention relates to the field of acoustic structure design technology and discloses a method for optimizing the acoustic structure of a celadon and bamboo composite material. The method includes establishing an overall structural model of a loudspeaker; determining the axial extension path of the main amplification channel in the model; constructing a curved surface of the loudspeaker shell that matches the main amplification channel; sequentially constructing a celadon rigid layer, a bamboo composite transition layer, and a bamboo woven diffusion layer along the shell thickness direction; dividing the celadon rigid layer into axial and circumferential sections and setting different thicknesses and shallow texture structures; establishing an acoustic structure coupling model and iteratively adjusting the structural parameters to obtain the target structural scheme. This invention solves the problems of the single shell material form and fragmented structural design methods in existing loudspeaker structures by sequentially setting a celadon rigid layer, a bamboo composite transition layer, and a bamboo woven diffusion layer along the thickness direction of the loudspeaker shell and performing a partitioned structural design along the extension direction of the main amplification channel.
