Fixation Assembly for Waterproof Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face reduced waterproof performance when subjected to extreme conditions such as being dropped or impacted, due to misalignment of loudspeakers and microphones through holes, compromising their reliability.
Innovation Solution
A fixation assembly comprising a first and second support that securely fixes an electroacoustic transducer to the shell of an electronic device, restricting its freedom and maintaining alignment with sound transmission channels, ensuring communication with sound transmission holes, even under extreme conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electroacoustic transducer is fixed to the shell using conventional methods, then the assembly is simple, but the transducer may misalign with sound transmission holes under extreme conditions
Solution Approach 1:
The fixation assembly is divided into two separate supports: a first support that defines a receiving space and sound transmission channel, and a second support that engages with the first support and the shell. This segmentation allows each component to perform its specific function independently, ensuring the transducer remains securely positioned and aligned with sound transmission holes even under extreme conditions, thereby improving waterproof reliability without excessive complexity
Solution Approach 2:
The fixation assembly acts as an intermediary structure between the electroacoustic transducer and the shell. It includes a first support with a receiving space for the transducer and a second support that engages with both the first support and the shell, creating a stable intermediate fixation system that prevents misalignment while maintaining reasonable device complexity
2Reliability
If the electroacoustic transducer is securely fixed to prevent misalignment, then waterproof reliability improves, but the freedom of the transducer is restricted
Solution Approach 1:
The fixation assembly provides a balanced dynamic solution: the first support defines a receiving space that accommodates the transducer, while the second support engages with both the first support and the shell to provide secure fixation. This dynamic balance ensures the transducer is firmly positioned to prevent misalignment under extreme conditions while maintaining appropriate operational freedom for normal functions

AI summary
A fixation assembly is configured to fix an electroacoustic transducer to a shell of the electronic device, and includes a first support and a second support. The first support defines a receiving space and a sound transmission channel communicating with the receiving space. The electroacoustic transducer is received in the receiving space. The second support is engaged with the first support and configured to restrict freedom of the transducer assembly cooperatively with the first support. Even when the electronic device is under extreme conditions, a relative position between the electroacoustic transducer and the fixation assembly remain unchanged. The second support is engaged with the shell to fix the first support and the electroacoustic transducer with the shell, such that the electroacoustic transducer is fixed relative to the shell, improving reliability of the electronic device under extreme conditions.
