Input Stick Buffer Structure for Microphone Noise Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Input devices used for video games often generate noise due to collisions between input members and other parts, particularly when a microphone is included, leading to interference with voice data.
Innovation Solution
The input device incorporates an exterior member with an opening, an input stick movable within, and a buffer member made of a different material than the opening and stick's outer surface, which reduces noise generation by minimizing collisions and sound transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an input stick is made movable inside an opening for game control operations, then the ease of operation is improved, but noise is generated when the input stick collides with the opening edges
Solution Approach 1:
A buffer member is introduced as an intermediary element between the input stick and the opening edge. This buffer member absorbs collision impacts and prevents direct contact between the input stick and the opening edge, thereby eliminating noise generation while preserving the movable operation functionality of the input stick.
Solution Approach 2:
The buffer member is pre-installed at the opening edge before the input stick operates. This cushioning element is positioned in advance to absorb potential collision impacts, preventing noise from occurring when the input stick moves or collides with the opening during game control operations.
2Adaptability or versatility
If a microphone is included in the input device for voice data acquisition, then the functionality is improved, but voice data is contaminated by collision noise
Solution Approach 1:
The buffer member serves as a mediator that isolates the collision noise source from the microphone. By absorbing impact energy and preventing direct contact between the input stick and opening edge, the buffer member protects the microphone from capturing collision noise, thereby preserving voice data quality while maintaining voice acquisition functionality.
3Adaptability or versatility
If the input stick is allowed to move freely for operational flexibility, then the adaptability is improved, but collision with other parts occurs causing sound
Solution Approach 1:
The buffer member is positioned at the opening edge as a protective intermediary. It allows the input stick to maintain its movable flexibility for various game control operations while simultaneously absorbing collision impacts, thereby preventing sound generation without restricting operational adaptability.

Function Achieved in This Case
This design effectively suppresses noise generation during input operations, enhancing the quality of voice data acquisition and reducing interference in voice recognition and communication.
Implementation Method 1
a buffer member that is provided on one of an inner edge of the opening and an outer peripheral surface of the input stick and is made of a material different from a material of the inner edge of the opening and from a material of the outer peripheral surface of the input stick. With this input device, noise generation can be suppressed.
Data Source
AI summary
Noise is prevented from occurring in voice data acquired by a microphone due to an operation of an input stick. An input device (10) includes an upper cabinet section (41) having an opening formed therein, an input stick (31) movable inside the opening, and a buffer member (46) that is provided on an inner edge of the opening of the upper cabinet section (41) and is made of a material different from a material of the inner edge of the opening and from a material of an outer peripheral surface of the input stick (31).
