Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sound generating devices for animal communication often face a trade-off between ruggedness and sound quality, particularly in adverse environments, and lack the ability to facilitate clear, high-quality sound transmission while being resistant to damage from liquids and contaminants.
Innovation Solution
The development of sound buttons with a dome-shaped design featuring a speaker and button cap assembly that allows sound transmission through holes with valves, which are displaced from the speaker location, and a waterproof KAPTON membrane, along with a PCB that connects to the speaker via wiring, providing improved sound transmissibility and resistance to damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the speaker is fully enclosed to protect it from liquids and contaminants, then reliability is improved, but sound quality and transmissibility deteriorate
Solution Approach 1:
The button cap assembly is designed with different properties in different regions: the housing provides waterproof protection, while the button cap itself contains holes for sound transmission. This local differentiation allows the structure to simultaneously protect the speaker from moisture while enabling acoustic output.
Solution Approach 2:
The button cap assembly acts as an intermediary structure between the speaker and the external environment. It provides a waterproof barrier while incorporating sound transmission holes, serving as a mediator that protects the speaker without completely blocking sound output.
2Object-generated harmful factors
If the speaker is exposed to avoid sound degradation, then sound quality is improved, but reliability deteriorates due to vulnerability from liquids and contaminants
Solution Approach 1:
The housing is designed to be waterproof while the button cap assembly contains specific holes for sound transmission. This local quality differentiation allows the speaker to be protected from moisture in the housing while still enabling acoustic output through the button cap holes.
Solution Approach 2:
The button cap assembly serves as an intermediary that allows sound to pass through while blocking liquids and contaminants from reaching the speaker. It mediates between the need for sound quality and the need for protection.
3Reliability
If a waterproof seal is applied to protect the speaker, then reliability is improved, but sound transmission is blocked
Solution Approach 1:
The button cap assembly is designed with specific holes in it, creating a local quality difference from the surrounding waterproof structure. This allows the seal to remain effective around the speaker while permitting sound transmission through the button cap holes.
Solution Approach 2:
The button cap assembly acts as an intermediary structure that integrates both waterproofing and sound transmission functions. It allows sound waves to pass through while maintaining the waterproof seal against the speaker.
4Object-generated harmful factors
If the button cap assembly is designed with holes for sound transmission, then sound quality is improved, but vulnerability to liquid intrusion increases
Solution Approach 1:
The holes in the button cap assembly are strategically positioned and designed to transmit sound while being positioned such that they do not directly expose the speaker to liquid intrusion. The local quality of the button cap differs from the housing, allowing sound transmission while maintaining protection.

AI summary
A sound button devices, systems, and methods for sound buttons capable of emitting sound using less power, greater sound transmissibility, and/or greater resistance to damage and that allow for training both non-humans and humans to communicate more effectively than previously possible In typical embodiments, the sound button may comprise a shell, a switch operably connected to a printed circuit board (“PCB”), a button cap assembly operably coupled to the shell, the button cap assembly comprising a button cap having at least one recess, the at least one recess having a hole; and a speaker facing toward the button cap, where, when a force is applied to the button cap, the button cap and the speaker move together to actuate the switch, thereby causing the speaker to emit a sound.
