Sound Source Synchronization Server for Multi-Device Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems face challenges in synchronizing sound source reproduction across multiple smartphones due to timing mismatches, difficulty in sharing reproduction positions, and concerns over private information sharing, making simultaneous music reproduction impractical.
Innovation Solution
A system comprising a user terminal and a sound source synchronization processing server that allows users to browse and select sound sources, transmit synchronization requests, and correct reproduction times, enabling synchronized sound source reproduction without separate network settings, while managing privacy through phone number management and disclosure settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If multiple smartphones reproduce sound sources simultaneously, then the output volume increases, but synchronization of reproduction timing becomes difficult
Solution Approach 1:
The patent introduces a server as an intermediary that collects reproduction position information from all smartphones and calculates corrected reproduction times. This mediator coordinates the reproduction timing by providing each smartphone with specific timing adjustments, enabling synchronized playback across multiple devices without requiring direct peer-to-peer synchronization between the smartphones themselves.
Solution Approach 2:
The system implements feedback by continuously monitoring the actual reproduction positions of sound sources on each smartphone and using this information to calculate appropriate reproduction time corrections. The server sends back adjusted timing instructions to each device based on their individual performance characteristics, creating a closed-loop control system that achieves synchronization despite hardware variations.
2Reliability
If users exchange phone numbers to synchronize sound sources, then synchronization can be achieved, but privacy security deteriorates
Solution Approach 1:
The server acts as a privacy-protecting intermediary that enables synchronization without direct user-to-user contact. Instead of requiring users to exchange personal information like phone numbers, the server mediates all communication, collecting necessary technical data for synchronization while keeping personal user information private and isolated on each device.
3Manufacturing precision
If reproduction position information is shared in real-time, then synchronization accuracy improves, but network dependency increases
Solution Approach 1:
The system performs preliminary collection of reproduction position information from all smartphones before calculating the final reproduction time corrections. By gathering all necessary data in advance and processing it centrally, the system reduces the need for continuous real-time network communication during the actual synchronization process, thereby lowering ongoing network dependency while maintaining accuracy.

AI summary
The present invention relates to a system for providing sound source reproduction information and has an object to provide a system for providing sound source reproduction information, in which the sound source reproduction information is provided for each user in the order of their distance from each user, and a user selectively browses sound source information of other users reproduced in the vicinity thereof and generates a synchronization request signal for the sound source information, such that reproduction of the sound source may be synchronized between users without performing any settings with each other.
