Networked Audio Receiver Control for Synchronized Volume and Band
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio systems require cumbersome individual adjustments for multiple receivers outputting the same audio data, as control operations are typically performed through buttons on the transmitter side, necessitating separate volume and band adjustments for each receiver.
Innovation Solution
An audio apparatus that automatically controls the output state of audio data among receivers, comprising a receiver, a sound emitter, a generator for creating sound emission control information, and a transmitter to send this information to other apparatuses, allowing synchronized volume and band adjustments across connected devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If control buttons are disposed on the transmitter side to control receivers, then the transmitter can control the receivers, but the receivers require individual adjustments which are cumbersome
Solution Approach 1:
The receiver automatically performs self-adjustment of volume and band based on control information received from the transmitter. The receiver's adjustment unit autonomously modifies its output parameters without requiring manual individual adjustment, making the system self-configuring and eliminating time-consuming manual settings.
Solution Approach 2:
The transmitter sends control information to the receiver, and the receiver automatically adjusts its parameters based on this feedback loop. This automated feedback mechanism allows the transmitter to control the receiver's volume and band settings without requiring manual intervention at the receiver side.
2Adaptability or versatility
If multiple receivers simultaneously output the same audio data, then audio coverage is improved, but volume and range adjustments must be individually balanced which is complex
Solution Approach 1:
The transmitter serves multiple receivers simultaneously with a single control interface. The control information generated by the transmitter is universally applicable to all connected receivers, allowing centralized control of multiple devices and eliminating the need for separate adjustment procedures for each receiver.
Solution Approach 2:
Each receiver automatically adjusts its own volume and band parameters based on the control information received from the transmitter. This self-adjusting capability simplifies the system by eliminating manual balancing operations while maintaining coordinated output across multiple receivers.
3Measurement precision
If manual adjustment of volume and band is performed for each receiver, then precise control is achieved, but the adjustment process is cumbersome
Solution Approach 1:
The transmitter generates control information containing precise volume and band settings and transmits this to the receivers. The receivers automatically apply these settings, maintaining precision control while eliminating manual adjustment operations. The feedback loop ensures accurate parameter transmission and application.
Solution Approach 2:
The receiver's adjustment unit automatically applies the control information received from the transmitter, achieving precise volume and band control without requiring manual intervention. This self-adjusting mechanism maintains measurement precision while dramatically improving ease of operation.

AI summary
An audio apparatus includes a network interface, a receiver, at least one storage, and at least one processor. The processor is configured to determine that the audio apparatus is in a state capable of communicating with the other audio apparatus via the network interface. The processor is also configured to receive audio data via the receiver transmitted from an external apparatus different from the other audio apparatus. The processor is also configured to output a sound based on the received audio data. The processor is also configured to transmit the sound emission control information stored in the at least one storage to the other audio apparatus. The sound emission control information includes one or more of a sound volume, and a frequency band.
