Solution Overview

Problem

Current surround sound systems fail to deliver personalized audio experiences to multiple listeners located at different positions, as they do not effectively account for individual listener positions and preferences, leading to suboptimal audio localization and quality.

Innovation Solution

A system comprising a media device with a processor and memory, connected to multiple speakers, uses a position module and audio profiles to deliver personalized audio by determining user device positions through calibration signals and triangulation, and applying customizable audio settings such as language and listening modes based on user preferences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional surround sound systems are used, then audio channels are separated and played through speakers at different locations, but the system fails to deliver personalized audio experiences to multiple listeners at different positions

Engineering Contradiction:
Improvepersonalized audio deliveryVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system performs preliminary calibration by determining the positions of multiple listeners and their audio preferences before actual audio playback. Audio profiles are pre-configured for each listener based on their location and preferences, enabling personalized audio delivery without real-time computation during playback

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The audio system is segmented into multiple independent audio profiles, each tailored to a specific listener's position and preferences. The overall audio signal is divided into separate channels that are independently processed and delivered to different speakers based on individual listener requirements

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If audio profiles are created for each listener position, then personalized audio experience is improved, but the process of determining user device positions and applying audio settings increases system complexity

Engineering Contradiction:
Improveaudio localization precisionVSAvoidposition determination complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

User devices perform self-service by determining their own positions through calibration signals. Each device receives calibration signals from speakers, calculates its position and orientation autonomously, and communicates this information back to the media device, eliminating the need for complex external tracking systems

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements feedback mechanisms where user devices report their determined positions and audio preferences back to the media device. This feedback loop enables the system to continuously optimize audio delivery based on actual listener positions and preferences

Inventive Principle:
Principle #23Feedback
