Game Machine Sound Invalidation During Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices with both operation and sound input parts face issues where operation sounds are inadvertently input into the sound input system, leading to uncomfortable noise during voice chat functions, especially when the parts are closely located or housed together.
Innovation Solution
An information processing device with an operation acceptance part, sound information processing part, and sound invalidation part that temporarily invalidates sound input to the sound input part during operations, preventing operation sounds from being transmitted and output to other users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the sound input part is located near the operation part or placed in one housing, then the device structure is compact and integration is improved, but operation sound is inadvertently input to the sound input part causing uncomfortable noise
Solution Approach 1:
The sound invalidation part preemptively invalidates sound input signals during operation periods before they can cause interference. When operation input is detected, the system proactively blocks subsequent sound inputs from the sound input part, preventing operation sounds from being transmitted through the network rather than reacting after the problem occurs
Solution Approach 2:
The sound invalidation part acts as an intermediary component between the sound input part and the sound information processing part. It selectively blocks sound input signals during operation periods while allowing normal sound processing during non-operation periods, mediating between the need for compact design and the need to prevent sound interference
2Productivity
If operation sound is input to the sound input part, then the sound transmission function operates continuously, but unnecessary sound is transmitted and output to the other party's side
Solution Approach 1:
The sound invalidation part implements periodic control of sound input validation based on operation states. During operation periods, sound input is invalidated; during non-operation periods, sound input is validated. This periodic switching ensures sound transmission only occurs when actually needed, eliminating continuous unnecessary transmission while maintaining functionality when required
Solution Approach 2:
The sound invalidation part applies different validation qualities to sound input signals based on temporal context. Instead of uniformly validating or invalidating all sound inputs, the system selectively invalidates sound inputs during operation periods while maintaining normal validation during non-operation periods, creating localized quality control in the sound processing pipeline

AI summary
A game machine 1 invalidates sound input to a microphone 13 for a given time period Tb when operation is performed with respect to the operation part 12. The game machine 1 switches from a silent state to an active state to start sound transmission through a communication part 18 if volume at a current time point exceeds a volume threshold, whereas it switches from the active state to the silent state to stop the sound transmission if the state where the volume at the current time point does not exceed the volume threshold continues for a given time period Tr. The game machine 1 prohibits switching to the active state and does not perform sound transmission when operation is performed with respect to the operation part 12 in the silent state, whereas it transmits sound when operation with respect to the operation part 12 is performed in the active state.
