Solution Overview
Problem
Portable appliances like iPads and iPhones face challenges in delivering high-quality audio while maintaining waterproofness, as scaled-down speakers require holes for sound delivery, compromising audio quality and manufacturing complexity.
Innovation Solution
An audio resonance device with a base member, stacked ceramic resonance element, and elastic elements that attach to the appliance without modifying it, enhancing audio quality by resonating with audio vibrations and providing a resonant chamber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If holes are configured on the portable appliance for sound delivery, then audio signal can be delivered, but waterproof requirement cannot be achieved
Solution Approach 1:
The patent introduces an audio resonance device as an intermediary component that attaches to the portable appliance without requiring holes. The device uses elastic elements to transmit vibrations from the appliance surface to the resonance element, enabling audio delivery while preserving the appliance's waterproof seal.
Solution Approach 2:
The patent replaces the traditional mechanical speaker hole configuration with a vibration-based acoustic coupling system. The elastic elements transmit mechanical vibrations through the appliance surface without creating openings, substituting the need for physical holes with a non-invasive vibration transmission mechanism.
2Volume of moving object
If scaled-down speakers are used to fit in portable appliances, then device size is reduced, but audio quality cannot be delivered
Solution Approach 1:
The patent leverages mechanical vibration and resonance to enhance audio quality. The resonance element, when excited by vibrations from the portable appliance, produces amplified acoustic output that compensates for the limitations of scaled-down speaker dimensions, delivering high-quality audio without requiring large physical space.
Solution Approach 2:
The patent changes the operating parameters by utilizing the natural resonance frequency of the resonance element. By tuning the system to resonate at specific frequencies, the device amplifies audio output quality without increasing physical size, transforming the limitations of miniaturization into an opportunity for frequency-selective audio enhancement.
3Manufacturing precision
If thinned speakers are used to resolve the foregoing issues, then audio quality is improved, but manufacturing process becomes complicated
Solution Approach 1:
The patent segments the audio enhancement function into a separate, attachable resonance device rather than integrating it into the appliance's manufacturing process. This segmentation allows the resonance element and elastic elements to be produced independently and assembled by simple attachment, avoiding complex manufacturing procedures while maintaining high audio quality.

AI summary
The audio resonance device contains a base member having a box shape with an open top side, a resonance element inside the base member having stacked ceramic layers, and at least two contact pieces on a top side, a cover member sealing the open top of the base member, and a number of elastic elements, each contacting a contact piece of the resonance element, and having an end extending through the cover member and contacting a portable appliance for picking up audio vibration from the portable appliance and delivering the audio vibration to the resonance element. The resonance element resonates with the audio vibration, and the base member provides a resonant chamber so that the audio quality from the portable appliance is enhanced. The portable appliance is not required of any modification such as opening holes.
