Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If low frequency sounds are generated using tuning forks, then the ability to reach longer distances and penetrate walls is improved, but the convenience of computer control and sequencing is worsened
Solution Approach 1:
The patent replaces manual mechanical control of tuning forks with an electromagnetic actuation system controlled by a computer. Electromagnetic actuators replace the need for physical striking or manual adjustment, enabling precise digital control of frequency and timing while maintaining the natural vibration characteristics of tuning forks for long-distance sound transmission.
Solution Approach 2:
The patent introduces a computer as an intermediary between the user and the tuning forks. The computer receives audio input, processes it through acoustic effect conversion, generates control signals, and sends them to electromagnetic actuators that drive the tuning forks. This intermediary system provides convenient computer control while preserving the physical vibration mechanism for effective sound transmission.
2Adaptability or versatility
If multiple tuning forks are used to produce low frequency sounds, then the richness of acoustic beats and listening experience is improved, but the complexity of controlling and sequencing them is worsened
Solution Approach 1:
The patent implements a universal computer-based control system that can manage multiple tuning forks through a single interface. The computer processes audio input and automatically generates coordinated control signals for all electromagnetic actuators, allowing one system to control multiple instruments simultaneously without requiring separate control mechanisms for each tuning fork.
Solution Approach 2:
The patent employs feedback mechanisms where the computer monitors and adjusts the operation of multiple tuning forks based on the desired acoustic output. The acoustic effect conversion process uses feedback from the audio input to dynamically control the timing and frequency of vibrations across all tuning forks, simplifying the sequencing complexity while maintaining rich acoustic beat production.

A set of N tuning forks with natural frequencies F1, to FN where FN is the highest frequency tuning fork where the one or more electromagnetic actuators are coupled to a tuning fork, such that when the one or more electromagnetic actuator is driven by the electrical signal the tuning fork vibrates.
Implementation Method 2
Individual tuning forks can generate low frequency tones or air waves, and these low frequency tones or air waves from multiple tuning forks can combine to produce low frequency sounds.

AI summary
A computer configured for translating an audio input into a low frequency output using an acoustic effect conversion with a signal generator connected to the computer that takes the low frequency output and generates an electrical signal to drive a set of electromagnetic actuator couple to a set of N tuning forks, such that when the electromagnetic actuators are driven by the electrical signal the coupled tuning forks vibrate. The acoustic effect conversion translates the audio input into digital instructions, such as MIDI and may use a sequencer. The audio input may have a frequency IS and the electrical output signal may have a frequency LF and LF=IS/N, where N maybe 9 or 12. The audio input may use a digital analog file such as .wav or mp3. The N tuning forks may be in a circular pattern on a plane pointing away from the center.
