Sound Output Module Integrated with Battery for Resonant Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with reduced thickness face challenges in securing resonant space for sound output modules, particularly for medium and low frequency band sound, as the available space is insufficient to ensure optimal audio performance.
Innovation Solution
The configuration involves a housing design where the sound output module is integrated with the battery, with one side surface of the module adjacent to the battery, and the module forms a side wall of the battery's mounting space, allowing for efficient use of space and securing resonant space in both length and thickness directions, while maintaining a small device thickness.

1Length of moving object
If the electronic device thickness is reduced to improve portability, then the device becomes more portable, but the resonant space for the sound output module becomes insufficient
Solution Approach 1:
The sound output module is integrated with the battery module, where the battery module serves dual purposes: providing power and forming part of the resonant space enclosure. The battery module includes a battery case that encloses the sound output module, creating a combined functional unit that reduces overall device thickness while maintaining sufficient resonant space volume.
Solution Approach 2:
The resonant space is extended in the length direction (along the device's long axis) rather than only in the thickness direction. The battery module is positioned to provide resonant space extension along the length dimension, allowing adequate resonant volume to be achieved without increasing device thickness.
2Reliability
If the resonant space is increased to improve audio performance, then the audio performance improves, but the device thickness increases
Solution Approach 1:
The resonant space is primarily extended in the length direction by positioning the battery module along the device's long axis. This dimensional strategy allows adequate resonant volume for medium and low frequency sound reproduction without increasing the device thickness dimension, thus maintaining slim profile while improving audio performance.
Solution Approach 2:
The battery module is designed to serve dual functions: power supply and resonant space enclosure. By integrating these functions, the design avoids adding separate components that would increase thickness, achieving improved audio performance through efficient space utilization.
3Adaptability or versatility
If various elements are included to provide multiple functions, then the functionality increases, but the mounting space becomes insufficient
Solution Approach 1:
The battery module is designed as a multi-functional component that simultaneously provides power supply, structural support, and resonant space enclosure. This integration reduces the total volume required for mounting various elements, as the battery module serves multiple purposes rather than requiring separate dedicated spaces for each function.
Solution Approach 2:
The battery module is designed to perform multiple functions: electrical power supply, mechanical support structure, and acoustic resonant space enclosure. This multi-functionality approach allows various elements to be included in the device without proportionally increasing mounting space requirements, as one component (battery module) fulfills multiple roles.
