Multi-Receiver Audio Output Synchronization for Balanced Sound Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio systems require cumbersome individual adjustments for multiple receivers outputting the same audio data, as control buttons on the transmitter side necessitate separate settings for each receiver, making balanced volume and frequency adjustments difficult.
Innovation Solution
An audio apparatus that includes a receiver, a sound emitter, a generator for creating sound emission control information, and a transmitter to automatically control the output state of audio data among receivers, allowing for synchronized volume and frequency adjustments across connected devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If control operations are performed from the transmitter side for multiple receivers, then the control structure is simple, but the adjustment of sound volumes and ranges becomes cumbersome and time-consuming
Solution Approach 1:
The patent inverts the traditional control direction by enabling receivers to autonomously adjust their output based on detected audio data characteristics and transmitted control information from other receivers. Instead of the transmitter controlling each receiver individually, receivers self-adjust based on peer-to-peer control information exchange, dramatically simplifying the adjustment process while maintaining balanced audio output across multiple devices
Solution Approach 2:
Each receiver is equipped with autonomous adjustment capabilities, automatically detecting audio data characteristics and adjusting its own sound emission parameters. The system enables receivers to serve themselves by autonomously balancing volume and range based on control information from other receivers, eliminating the need for manual individual adjustments and reducing operational complexity
2Manufacturing precision
If individual adjustments are made for each receiver, then the sound balance can be optimized, but the adjustment process becomes time-consuming and complex
Solution Approach 1:
The patent implements a feedback mechanism where receivers transmit control information about their output state to other receivers. Each receiver uses this feedback to automatically adjust its sound emission parameters, achieving optimized sound balance across the system without manual intervention. The continuous feedback loop enables dynamic adaptation to maintain optimal audio balance
Solution Approach 2:
The system performs preliminary detection of audio data characteristics and automatic generation of control information before manual adjustment would be required. By pre-configuring receivers with autonomous adjustment capabilities and having them continuously monitor and adapt their output based on detected characteristics, the system achieves sound balance optimization without time-consuming manual adjustments

AI summary
An audio apparatus includes: a receiver which receives audio data transmitted by a broadcast method from an external apparatus; a sound emitter which performs sound emission of the audio data received by the receiver; a generator which generates sound emission control information relating to sound emission of other apparatus which can receive the audio data; and a transmitter which transmits the sound emission control information generated by the generator to the other apparatus.
