Microphone Slide and Push Mechanism for Noise Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional microphone devices with slide switches are inconvenient for short-term use, prone to noise output when handed over or dropped, and can suffer from incorrect operation noise due to the need for simultaneous slide and push operations, leading to a complex configuration.
Innovation Solution
A microphone device with separate operating parts for power-on and power-off, where a slide member and push member are interlocked through inclined surfaces and a spring mechanism, allowing independent operation and preventing incorrect operation, while maintaining a simple configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional slide switch is used for power-on and power-off, then the microphone can be operated, but independent operation is required for power-on and power-off which is inconvenient for short-term use
Solution Approach 1:
The single slide switch is segmented into two independent operating portions: a first operating portion for power-on and a second operating portion for power-off. This allows users to perform only the necessary operation (power-on or power-off) without needing to operate both directions, improving convenience for short-term use while maintaining clear functional separation.
2Adaptability or versatility
If the microphone is handed over while powered on, then the microphone can be used by another user, but touch noise and impact sound are picked up and output from the speaker
Solution Approach 1:
The system performs preliminary action by automatically turning off the microphone when it is handed over (detected through sensor signals indicating handover). This prevents touch noise and impact sound from being picked up and output during the handover process, while still allowing seamless transfer to another user.
3Adaptability or versatility
If both slide operation and push-down operation are performed to one movable piece, then the microphone can be operated for both long-term and short-term use, but incorrect operation causes the movable piece to slide unintentionally producing rubbing noise
Solution Approach 1:
The single movable piece is segmented into two separate movable pieces: a first movable piece for slide operation (power-on/power-off) and a second movable piece for push-down operation (microphone stand mode). This physical separation prevents incorrect operation where one piece might accidentally slide while being pressed, eliminating rubbing noise while maintaining flexibility for different usage scenarios.
4Reliability
If a plurality of switches are provided to prevent incorrect operation, then incorrect operation can be prevented, but the configuration of the microphone becomes complicated
Solution Approach 1:
Instead of adding multiple switches to prevent incorrect operation, the system segments the existing switch structure into distinct operational portions and movable pieces. Each portion is dedicated to a specific function (power-on, power-off, or stand mode), which naturally prevents incorrect operation without requiring additional switches or complex control logic.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device is highly convenient for short-term use, reduces noise output when handed over or dropped, and prevents incorrect operation noise, achieving a simple and effective design.
Implementation Method 1
a spring member arranged between the electrical contact component and the push member, and biasing the push member in an opposite direction to the pushing direction
Implementation Method 2
a first inclined surface provided on the slide member, and a second inclined surface provided on the push member, wherein when the slide member is slid from the nonconductive position to the conductive position, the first inclined surface presses the second inclined surface to thereby move the push member in the pushing direction
Data Source
AI summary
A microphone has a slide member and a push member. The slide member has a slide knob, and a conductive state and a nonconductive state are switched according to operation of the slide knob. The push member holds a switch in the conductive state while a push button is pushed. A mechanism interlocking of the slide member and the push member is provided and interlocks operation of the slide member with the push member by converting movement of the slide member in a sliding direction into movement of the push member in a pushing direction, the slide knob and the push button are separated from each other in the sliding direction.
