Speaker Frame Locking Mechanism for Jam-Free Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing loudspeaker connection systems face challenges in stability and fluidity during assembly and disassembly, leading to potential jamming and requiring manual effort for locking and unlocking, which complicates the assembly process of large loudspeaker arrays.
Innovation Solution
A loudspeaker frame with a connection device featuring a locking system comprising two legs, a slider with guide elements, elastic members, and a selector screw, along with a locking rod and actuator, allowing for automatic assembly and disassembly by moving the slider and selector screw between locked and armed configurations, ensuring secure and fluid connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking system with slider is used to connect loudspeaker enclosures, then the connection can be secured, but the locking system may jam or derail during assembly and disassembly
Solution Approach 1:
Guide elements are introduced as intermediary components between the slider and the locking system structure. These guide elements constrain the slider's movement path, preventing derailment while maintaining smooth operation during assembly and disassembly
Solution Approach 2:
The guide elements are designed to preemptively prevent jamming by maintaining proper alignment and spacing of the slider throughout its travel range, eliminating the risk of malfunction before it can occur
2Ease of operation
If manual locking and unlocking operations are required, then the locking system can be controlled, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The locking system is designed to automatically perform locking and unlocking operations through the movement of the slider. The elastic member provides self-return functionality, and the locking rod automatically engages or disengages based on slider position, eliminating the need for manual intervention and significantly improving assembly speed
3Adaptability or versatility
If the slider is allowed to move freely between positions, then the locking system is flexible, but the slider may derail from its sliding zone
Solution Approach 1:
Guide elements serve as intermediary structures that define the slider's movement path. These elements allow the slider to move freely between locked and unlocked positions while simultaneously preventing derailment by constraining the slider within its designated sliding zone

AI summary
An acoustic enclosure frame (2) comprising a connection device (21) for connecting to another acoustic enclosure, the connection device (21) having an eyelet (210) and a locking system (3), the locking system (3) having a front tab (31a) and a rear tab (31b), a slider (32) disposed between the two tabs (31a; 31b) and configured to slide between a raised position and a lowered position under the action of a first elastic element connected to the slider (32), and an actuator (38) configured to assume a pulled position and a pushed position. The locking system (3) being configured to assume a locked position and an armed position, the locking system (3) transitioning from the locked position to the armed position by movement of the actuator (38) and from the armed position to the locked position by movement of the slider (32) from the lower position to the raised position.
