Acoustic System Synchronizing Lyrics Display with Music Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumers often purchase musical pieces without access to detailed lyrics, which limits their enjoyment, as lyrics data is typically not included with the musical piece data, and both consumers and providers desire a way to enhance the listening experience by viewing lyrics alongside the music.
Innovation Solution
An acoustic system that wirelessly communicates with a communication device to output musical pieces and display corresponding lyrics in sync, using a counter to ensure timely lyric display, even with infrequent reproduction position signals, and optionally acquiring lyrics data from a server or communication device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If lyrics data is not included with musical piece data to reduce data size and simplify distribution, then storage and transmission efficiency is improved, but user access to detailed lyrics is lost
Solution Approach 1:
The patent introduces a server as an intermediary component that stores lyrics data separately from musical piece data. The system retrieves lyrics from this server based on track identifiers, enabling access to detailed lyrics without embedding them in the original music files. This resolves the contradiction by maintaining small music file sizes while providing comprehensive lyrics information through the intermediary server.
Solution Approach 2:
The patent separates lyrics data from musical piece data into a different dimension - storing music data in one location and lyrics data in another (the server). Instead of combining both in the same data structure, the system uses external identifiers to link them, effectively moving lyrics information to another dimensional space that can be accessed on-demand without increasing the size of the original music files.
2Loss of energy
If reproduction position signals are transmitted infrequently to reduce communication overhead, then network traffic is reduced, but lyric display synchronization accuracy deteriorates
Solution Approach 1:
The system performs preliminary actions by accumulating multiple reproduction position signals over time and processing them together to calculate average timing values. This preliminary accumulation of data allows the system to maintain accurate timing information even when individual signals are spaced far apart, reducing the need for frequent transmissions while preserving synchronization accuracy.
Solution Approach 2:
The patent implements feedback mechanisms where the system continuously monitors the timing between reproduction position signals and adjusts its processing accordingly. By using feedback from accumulated timing data, the system can compensate for the lower frequency of signals and maintain accurate lyric display synchronization without requiring high-rate continuous signaling.

AI summary
An acoustic system comprises an output unit, a communication unit, a first output control unit, and a second output control unit. The output unit is configured to be capable of outputting a sound and an image. The communication unit is configured to be capable of communicating with an external device. The first output control unit is configured to receive, from a communication device that transmits a reproduction signal for acoustic data, the reproduction signal via the communication unit and to cause the output unit to output a sound based on the reproduction signal, to thereby perform reproduction of a series of sounds represented by the acoustic data. The second output control unit is configured to cause the output unit to output, as the image, a word corresponding to the sound outputted by the output unit among the series of sounds represented by the acoustic data.
