Speaker Sound-Dispersing Cone for Uniform 360-Degree Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispersion cones on speakers, such as those on boat towers, do not effectively redirect sound from both tweeters and woofers, limiting sound coverage area and interfering with the sound stage.
Innovation Solution
A sound dispersion cone positioned concentrically with both the tweeter and woofer, redirecting sound radially and allowing it to pass through, with a design that minimizes interference and provides uniform sound distribution across 360 degrees.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a dispersion cone is used to redirect sound from a tweeter, then sound redirection is achieved, but sound from other speaker elements (woofer) is not redirected and coverage area is limited
Solution Approach 1:
The dispersion cone is designed to serve multiple speaker elements (tweeter and woofer) simultaneously, making it a universal solution that redirects sound from different frequency ranges rather than being dedicated to a single tweeter element
2Area of stationary object
If a dispersion cone with supporting structure is used, then sound redirection is achieved, but the structure interferes with the sound stage
Solution Approach 1:
The supporting structure is completely removed from the design. The dispersion cone is mounted directly to the baffle without any traditional supporting framework, eliminating the source of sound stage interference while maintaining the sound redirection function
Solution Approach 2:
The dispersion cone is positioned within the speaker assembly in a nested arrangement where the cone itself becomes part of the speaker structure, eliminating the need for separate supporting structures that would interfere with the sound stage
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures a consistent and uniform sound presentation for listeners around the speaker, minimizing sound changes due to movement, by effectively distributing sound from both tweeter and woofer elements.
Implementation Method 1
a dispersion cone positioned concentrically with both the tweeter and woofer, redirecting sound radially

AI summary
An apparatus (100), including: a speaker (152, 154); a baffle (104) surrounding the speaker; and a dispersion cone (106) positioned forward of, aligned with, and pointing toward the speaker and having a dispersion surface (120) with: a dispersion surface central section (122); a dispersion surface surrounding section (124) therearound; and a transition (126) therebetween. From a tip (122T) of the dispersion cone outward the dispersion surface central section defines a concave cross-sectional shape (170), the dispersion surface surrounding section defines a less concave cross-sectional shape (172) than the concave cross-sectional shape of the dispersion surface central section, and the transition comprises an inflection point (124IP). A distance of each section of the dispersion surface forward of the speaker progressively increases with increasing radial distance from a radial center of the dispersion surface.
