Adjustable Speaker Frame With Interwoven Ribs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing speaker frames rely on springs or tensioning mechanisms to adjust the firing direction of speakers, which are not adaptable to different sizes and shapes, and do not allow for efficient sound transmission.
Innovation Solution
An adjustable speaker frame with interwoven webs, ribs, or fingers that provide an open structure for sound transmission, allowing for rotation and pivoting in all directions, and can be scaled to accommodate various speaker sizes and shapes, using a clam-shell design with a spring for secure mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If springs or tensioning mechanisms are used to adjust speaker firing direction, then the speaker can be positioned at different angles, but the device becomes complex and cannot accommodate different speaker sizes and shapes
Solution Approach 1:
The frame is divided into multiple discrete ribs that can independently flex and pivot. Each rib acts as an independent segment that can be positioned to accommodate different speaker sizes and shapes, eliminating the need for complex spring mechanisms while providing adjustable positioning capability.
Solution Approach 2:
The rigid frame structure is transformed into a dynamic structure where the ribs can flex and pivot. This dynamic capability allows the frame to adapt to different speaker configurations without requiring separate adjustment mechanisms for each speaker size or shape.
2Reliability
If solid concave and convex surfaces are used to hold the speaker, then the speaker is securely retained, but sound transmission is blocked
Solution Approach 1:
Instead of solid surfaces, the invention uses a grid of ribs that creates an open, porous-like structure. This allows sound waves to pass through the frame structure while the ribs provide sufficient contact points to securely retain the speaker.
Solution Approach 2:
The continuous solid surface is segmented into discrete ribs. This segmentation maintains the retention function by providing multiple contact points while eliminating the sound blockage problem inherent in solid surfaces.
3Object-generated harmful factors
If an open frame with webs, ribs or fingers is used, then sound transmission is improved and material usage is reduced, but the speaker mounting security decreases
Solution Approach 1:
The ribs are designed with curved surfaces that conform to the speaker housing. These curved surfaces provide increased contact area and mechanical interlocking, enhancing mounting security while maintaining the open structure for sound transmission.
Solution Approach 2:
The rib geometry is pre-designed to flex into position during assembly, creating a snap-fit or interference fit that secures the speaker. This preliminary geometric design ensures secure mounting without requiring additional fastening elements.

AI summary
Improvements to an adjustable speaker within a frame is disclosed. The adjustment of the speaker allows for rotation or pivoting on a plurality of webs, ribs or fingers. The plurality of webs, ribs or fingers provide a plurality of bearing surfaces. The webs, ribs or fingers provide an open frame that requires less material and allows for sound transmission both in-front of the speaker and around the speaker. The frame can be scaled to be larger or smaller to accommodate different diameter and depth speakers. It is also contemplated that speakers frame can be accommodate both round and oblong shapes. The frame is a clam-shell mesh. The clam-shell captures the speaker between the two components. The two components essentially snap together to secure the speaker. The webs, ribs or fingers frame allows pivoting with a compression or tension member of a spring.
