Solution Overview
Problem
Existing loudspeaker devices do not consider the impact of key modules on the working state of the speaker component, which can reduce the volume generated by the speaker.
Innovation Solution
A loudspeaker device design that includes a support connector with a speaker component, an earphone core, and a core housing, which accommodates a control circuit and battery to drive the earphone core for sound production, while considering the impact on the speaker component's working state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a key module is added to the loudspeaker device to enable user interactions (such as pausing/playing music and answering calls), then the functionality and ease of operation are improved, but the volume generated by the speaker component is reduced
Solution Approach 1:
The loudspeaker device is divided into separate functional modules: a speaker component for sound generation and a key module for user interaction. The key module includes a key component with first contact points connected to the speaker component and a control component with second contact points. This segmentation allows independent optimization of each module's performance while maintaining their functional integration through the support connector.
Solution Approach 2:
A support connector is introduced as an intermediary component between the speaker component and the key module. The support connector includes a support body with a first contact point connected to the speaker component and a second contact point connected to the key component. This intermediary structure enables electrical and mechanical connection while isolating the key module's impact from the speaker component, thereby maintaining speaker performance while adding interaction functionality.
2Adaptability or versatility
If a key module with multiple contact points and control circuits is integrated into the loudspeaker device, then the adaptability and functionality are improved, but the device complexity increases
Solution Approach 1:
The key module is designed as a universal component that can perform multiple functions: it includes a key component with multiple contact points for different input operations and a control component with multiple contact points for various control functions. This multi-functional design allows a single module to handle diverse user interactions (pausing, playing, answering calls) without requiring separate dedicated components for each function, thereby improving adaptability while managing complexity.
Solution Approach 2:
The key module is nested within the overall loudspeaker device structure, with the key component and control component integrated into a compact assembly that connects to the speaker component through the support connector. This nesting approach allows the complex key module functionality to be contained within a standardized interface, reducing the apparent complexity of the overall device while maintaining full functional versatility.
