Modular Loudspeaker Axis Assembly for Omnidirectional Sound
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional loudspeaker devices are difficult to assemble and deliver due to their large size, which hinders the creation of modularized systems that can provide better sound quality by simulating a point sound source with omnidirectional sound fields.
Innovation Solution
A modularized loudspeaker device comprising multiple speaker modules arranged along a central axis, with specific plate structures and housings that allow for easy assembly and enhanced sound propagation, including a cross-shaped first speaker module, U-shaped second module, and bass reflex tubes, surrounded by a hollow frame and dustproof mesh for structural strength and omnidirectional sound generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional speaker systems integrate multiple speaker units to simulate a point sound source with omnidirectional sound field, then sound quality is improved, but device size becomes large and difficult to assemble and deliver
Solution Approach 1:
The loudspeaker device is divided into multiple independent modules (first module with two speaker units, second module with one speaker unit, third module with one speaker unit) that can be separately manufactured, transported, and assembled. Each module contains speaker units facing different directions, and the modules are connected via coupling structures (first coupling structure, second coupling structure) to form the complete omnidirectional sound system.
2Reliability
If multiple speaker units are integrated into a single device to achieve omnidirectional sound field, then sound quality is improved, but device complexity increases
Solution Approach 1:
The complex multi-speaker system is segmented into three manageable modules, each with specific functions. The first module contains two speaker units facing different directions, the second module has one speaker unit, and the third module has one speaker unit. This segmentation reduces the complexity of individual modules while achieving the overall omnidirectional sound field goal.
Solution Approach 2:
The coupling structures serve multiple functions: they connect different modules together, provide structural support, enable signal transmission between modules, and facilitate modular assembly and disassembly. This multi-functionality reduces the need for separate components for each function.

AI summary
A loudspeaker device is provided, including a first speaker module, a second speaker module, and a third speaker module. The first speaker module includes first, second, third, fourth, and fifth speaker units facing different directions. The second speaker module includes a sixth speaker unit, and the third speaker module includes a seventh speaker unit. The first, second, third, fourth, fifth, sixth, and seventh speaker units are arranged along a central axis of the loudspeaker device, and the output sound frequencies of the first, second, and third speaker units are less than those of the fourth, fifth, sixth, and seventh speaker units.
