Solution Overview

Problem

Conventional loudspeaker alignments suffer from interactions with surrounding surfaces and line of sight impediments, leading to reduced auditory clarity, uneven dispersion, and energy loss due to cancellations and artificial frequency limitations, requiring complex control equipment and precise placement.

Innovation Solution

A manipulated vortex waveguide loudspeaker alignment featuring a driver baffle, output flare baffles, waveguide baffles, and pressure baffles arranged to support audio transducers, providing frequency-independent amplification and even dispersion, with de-correlated sound and reflection resistance, allowing energy to be re-energized and reintroduced across transducer sides.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If conventional loudspeaker alignments are used, then the loudspeaker can reproduce sound, but the auditory clarity is reduced due to wave interactions with surrounding surfaces and line of sight impediments

Engineering Contradiction:
Improveauditory clarityVSAvoidcomplex control equipment and precise placement
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The loudspeaker is divided into multiple independent transducers arranged in a specific geometric configuration. Each transducer operates independently to create a distributed sound field, eliminating the need for complex control systems and precise placement requirements while maintaining auditory clarity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from conventional planar loudspeaker arrangements to a three-dimensional spatial configuration with transducers positioned at specific coordinates. This dimensional change creates a volumetric sound field that is less susceptible to surface interactions and line of sight impediments, improving auditory clarity without requiring complex control equipment.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Loss of energy

If conventional loudspeaker alignments are used, then the loudspeaker can produce sound, but energy is lost due to cancellations and node reinforcement effects

Engineering Contradiction:
Improveauditory energy lossVSAvoidcarefully controlled placement
Core Design Contradiction:
Loss of energyVSEase of operation

Solution Approach 1:

The patent employs an asymmetric arrangement of transducers with different positions and orientations rather than a symmetric conventional configuration. This asymmetry disrupts the formation of standing waves and node reinforcement patterns, reducing energy loss from cancellations while eliminating the need for carefully controlled placement.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The patent changes key parameters including transducer spacing, orientation angles, and positional coordinates to optimize the sound field distribution. These parameter changes minimize interference effects and energy loss from cancellations while making the system less sensitive to placement variations.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If conventional loudspeaker alignments are used, then the loudspeaker can reproduce full sound spectrum, but frequency response is artificially limited due to transducer tuning requirements

Engineering Contradiction:
Improvefrequency response rangeVSAvoidtransducer tuning control
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent uses multiple identical or similar transducers that can each operate across a broad frequency range. By distributing the sound production across multiple transducers in a three-dimensional arrangement, the system achieves extended frequency response without requiring complex tuning of individual transducers, as each transducer operates independently within its natural frequency capabilities.

Inventive Principle:
Principle #6Universality (Multi-functionality)
