Modular Acoustic Enclosure for Compact Speaker Customization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing loudspeaker enclosures are limited in their ability to easily change appearance without altering the enclosure design, and current solutions for modifying shape and aesthetics often require additional parts and increase the external dimensions, compromising acoustic performance and compactness.
Innovation Solution
An acoustic enclosure composed of two half-boxes that can be assembled end-to-end, featuring internal partitions to define optimized acoustic chambers, ribs for sound guidance, and a modular outer shell for easy customization, ensuring maximum compactness and acoustic performance while allowing easy modification of the enclosure's appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the acoustic enclosure is covered with a casing to change appearance, then aesthetic customization is improved, but the shape modification is limited and additional parts are required
Solution Approach 1:
The enclosure is divided into two half-boxes that can be assembled in different configurations. Each half-box can be independently designed and manufactured, allowing flexible combination to create various enclosure shapes and sizes while maintaining acoustic performance. This segmentation enables appearance customization without requiring additional casing parts.
Solution Approach 2:
The half-box design serves multiple functions: it provides the acoustic enclosure structure, enables shape customization through different assembly configurations, and eliminates the need for separate casing components. The same half-boxes can be assembled in various orientations to create different enclosure geometries for different aesthetic requirements.
2Adaptability or versatility
If different loudspeakers are designed from the same acoustic enclosure by integrating it into different types of enclosures, then appearance customization is improved, but external dimensions increase and acoustic performance deteriorates
Solution Approach 1:
By segmenting the enclosure into two half-boxes, the design achieves compactness while allowing shape variation. The half-boxes can be assembled end-to-end or side-by-side depending on the desired geometry, eliminating the need for oversized external enclosures. This maintains optimal acoustic chamber volumes without increasing external dimensions.
Solution Approach 2:
The half-box configuration allows the enclosure to adapt its shape in multiple spatial dimensions. By changing the assembly orientation of the half-boxes, different enclosure geometries can be achieved without adding volume, effectively utilizing space in different dimensional arrangements to accommodate various speaker configurations.
3Ease of manufacture
If the acoustic enclosure is designed with fixed shape, then manufacturing simplicity is improved, but appearance customization capability deteriorates
Solution Approach 1:
The enclosure is segmented into standardized half-box modules that can be manufactured using simple, repeatable processes. Each half-box is designed with uniform features for easy manufacturing, yet the modular nature allows these simple components to be assembled into enclosures with varied appearances, maintaining manufacturing simplicity while enabling customization.
4Adaptability or versatility
If additional parts are added to allow adaptation to different shapes, then appearance customization is improved, but device complexity and external dimensions increase
Solution Approach 1:
The half-box design is universally applicable for creating enclosures of different shapes without requiring additional adaptation parts. The same half-box components can be assembled in various configurations to achieve different geometries, making the system inherently adaptable without adding complexity or extra parts for shape modification.

AI summary
Acoustic box (2), comprising two half-boxes (15a, 15b) assembled with each other and each comprising an internal half-partition (20), the acoustic box being arranged so that, when assembled, the two half-boxes are positioned head to tail so that the first end of each half-box is positioned at the level of the second end of the other half-box, and the internal half-partitions extend in the extension of one another to form an internal partition of the acoustic box which defines inside the acoustic box two acoustic chambers (22a, 22b) each intended to accommodate one of the two loudspeakers (3).
