Audio Output Volume Interface for Balanced Multi-Speaker Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack a method to effectively control the volumes of individual audio output apparatuses in a home network system while maintaining the balance among them, especially in environments without a mixer, such as PA systems.
Innovation Solution
A control terminal apparatus with a transmission unit, display unit, and operation detector that allows for individual and collective volume control of audio output apparatuses, displaying clear setting ranges and maintaining volume balance through a master volume setting section.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual volume control for each audio output apparatus is implemented, then volume adjustment flexibility is improved, but control complexity increases
Solution Approach 1:
The control interface is segmented into individual volume control sections for each audio output apparatus, allowing independent adjustment of each device's volume while maintaining a structured, organized layout that prevents control complexity from becoming overwhelming
Solution Approach 2:
The master volume setting section provides multi-functional capability by enabling both individual volume control through individual sections and collective volume control through the master section, allowing the system to adapt to different control needs without requiring separate control mechanisms
2Ease of operation
If master volume control is added to maintain volume balance, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The master volume setting section combines the control functions of multiple individual volume controls into a single interface element, allowing users to adjust the volume of all audio output apparatuses simultaneously while maintaining the underlying individual control capabilities
Solution Approach 2:
The master volume setting section serves multiple functions: it can control all audio output apparatuses collectively, maintain volume balance across devices, and work in conjunction with individual volume control sections, providing a versatile control mechanism that reduces operational steps
3Measurement precision
If clear display of setting changeable range is implemented, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The display unit uses visual indicators such as color-coded ranges or highlighted areas to clearly show the setting changeable range in the master volume setting section, allowing users to immediately understand the valid adjustment range without complex explanations or additional controls

AI summary
A control terminal apparatus includes a transmission unit transmitting a control signal to audio output apparatuses, a display unit, an operation detector detecting an operation associated with display content, and a controller displaying individual volume setting sections which correspond to the audio output apparatuses and which include operation members performing variable operations of volume settings while volume setting states are displayed, displaying a master volume setting section including an operation member performing collective variable operation while the volume balance of the audio output apparatuses is maintained, executing clear display of a setting changeable range in which the volume balance is maintained in the master volume setting section, generating, when the operation detector detects an operation performed on one of the individual volume setting sections or the master volume setting section, a control signal corresponding to content of the operation, and causing the transmission unit to transmit the control signal.
