Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional audio noise cancellation apparatus are used, then sound quality can be improved, but the device complexity and cost increase significantly
Solution Approach 1:
The patent extracts only the essential resonant frequency treatment function from complex conventional noise cancellation systems. By using a simple crystalline resonator tuned to specific frequencies, it isolates and addresses only the spurious harmonics problem rather than attempting to cancel all noise components, thereby achieving sound quality improvement with minimal device complexity
Solution Approach 2:
The invention replaces expensive conventional noise cancellation apparatus with inexpensive crystalline resonators that can be easily manufactured and deployed. These simple resonant elements provide effective harmonic reduction at a fraction of the cost of complex active noise cancellation systems
2Reliability
If conventional audio noise cancellation apparatus are used, then sound quality can be improved, but the cost increases significantly
Solution Approach 1:
The patent employs inexpensive crystalline resonators that can be mass-produced using standard manufacturing techniques. These simple resonant elements replace costly conventional noise cancellation components, achieving effective harmonic reduction at minimal cost while maintaining ease of manufacture and deployment
3Reliability
If conventional audio noise cancellation apparatus are used, then sound distortion can be reduced, but they cannot effectively address spurious harmonics introduced by room acoustics
Solution Approach 1:
The patent applies resonators with specific frequency tuning characteristics matched to particular room acoustic conditions. Each resonator is designed with local quality parameters (resonant frequency, Q-factor) optimized for the specific spurious harmonics generated by the room's acoustics, enabling effective adaptation to different acoustic environments
Solution Approach 2:
The invention adjusts resonator parameters such as resonant frequency and damping characteristics to match the specific spurious harmonics present in different room acoustic environments. By changing these parameters, the system adapts to various acoustic conditions and effectively reduces room-induced harmonics

Function Achieved in This Case
The solution effectively reduces random and spurious harmonics, enhancing sound clarity and quality by producing harmonized high frequency mechanical and electromagnetic waves, making the sound more natural and pleasing to listeners.
Implementation Method 1
Located at the bottom of the hollow chamber of the outer cup is a crystalline material (e.g., quartz) that resonates in response to the high frequency energy generated by the source
Implementation Method 2
The crystalline material is excited by the high frequency energy and generates high frequency mechanical (e.g., sound) and electromagnetic waves
Implementation Method 3
A dispersion horn that is manufactured from a sound-reflecting material (e.g., aluminum) is seated atop the cover inside the outer cup
Data Source
AI summary
A high frequency energy converter which has application as an acoustic actuator for converting incoming high frequency energy into outgoing harmonized high frequency mechanical (e.g., sound) and electromagnetic waves. The energy converter is adapted to improve the quality of sound heard by a listener by reducing random and spurious harmonics that are introduced by the environment in which the listener is located. The energy converter includes an outer body and a reactive crystalline material (e.g., quartz) lying at the bottom of the outer body that is responsive to the incoming high frequency energy. A dispersion horn is located at the top of the outer body to be seated upon the crystalline material. The dispersion horn has a throat extending therethrough so that both incoming high frequency energy and outgoing high frequency mechanical and electromagnetic waves are transmitted through the throat of the horn in opposite directions.
