Coil Spring Game Call Volume and Tone Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing game calls face challenges in enhancing volume and stabilizing tones without increasing air pressure or user effort, and these issues are not adequately addressed across different types of game calls, including reed and friction-type calls.
Innovation Solution
Incorporating an unrestrained coil spring within the airstream column of game calls, secured at one end and free to vibrate along its length, which increases sound volume and stabilizes tones by creating a whirlwind effect when air is blown through.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an unrestrained coil spring is added to enhance volume and stabilize tones, then sound quality and ease of operation improve, but device complexity increases
Solution Approach 1:
The game call is divided into functional segments: the mouthpiece for sound production, the coil spring for tone stabilization and volume enhancement, and the tube for air passage. This segmentation allows each component to be optimized independently while maintaining overall simplicity.
Solution Approach 2:
The coil spring is positioned to vibrate mechanically when air passes through it, creating a whirlwind effect that stabilizes tones and enhances volume. This mechanical vibration principle transforms the spring into an active sound-modifying element without requiring electronic or complex mechanical mechanisms.
2Ease of operation
If air pressure is increased to produce higher tones, then tone range improves, but user effort and energy consumption increase
Solution Approach 1:
The coil spring vibrates at specific frequencies when air passes through it, creating resonance that stabilizes and enhances higher tones. This mechanical resonance allows users to produce higher pitches with less air pressure, as the spring's natural vibration frequencies amplify the sound rather than requiring forced high-pressure air flow.
Solution Approach 2:
The coil spring changes the physical parameters of the air stream by introducing controlled turbulence and vibration. This transforms the laminar air flow into a turbulent, vibrating flow that produces richer, more stable tones at lower pressure requirements, effectively changing the flow regime to achieve better sound quality with less energy input.
3Reliability
If a coil spring is secured at one end and unrestrained at the other, then tone stabilization improves, but manufacturing precision requirements increase
Solution Approach 1:
The securing mechanism is segmented into a simple mounting point at one end of the coil spring, allowing the spring to remain free and unrestrained along its length. This segmentation enables the spring to vibrate naturally while maintaining a simple, low-precision mounting structure that does not require complex fixation mechanisms.
Solution Approach 2:
The coil spring's physical parameters (coil diameter, wire thickness, length) are selected to provide sufficient structural stability for tone stabilization while maintaining ease of installation. The parameters are optimized to achieve reliable tone stabilization with minimal manufacturing precision requirements, balancing performance with manufacturability.

AI summary
The present invention utilizes a sized coil spring placed in the end of game call tubes, or mouthpieces that go into such tubes. When air is blown into the tube or mouthpiece, the air passes over and through the coil spring, causing the spring to vibrate and make a whirlwind effect. The vibrating coil spring increases the volume of the sound and also stabilizes each tone created on the mouthpiece or tube. The higher tones, or notes, are more easily obtained and become easier to reach and hold with consistency. The coil spring also helps to increase back pressure, making it easier to blow into call with less air to make the call work. This invention can be used in all types of game calls, such as calls for elk, deer, moose, wolves, predators, geese, ducks, and even some turkey calls. The invention makes the desired sounds more realistic and user friendly.
