Bone Conduction Microphone Integrated Switch Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bone conduction microphones require complex operations to collect vocal cord vibrations, often involving separate switches and surfaces for contact, which can be cumbersome and inefficient, especially in noisy environments like construction sites.
Innovation Solution
A bone conduction microphone design with a vibration collection unit that comes into contact with the human body and a switch integrated on the same side, allowing for simple operation by aligning the switch activation direction parallel to the vibration collection direction, enabling easy on/off functionality with a single action.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the switch is disposed on a side of the vibration collection unit opposite to the contact side, then the operation direction is parallel to the vibration collection direction, but the device structure becomes more complex
Solution Approach 1:
The patent combines the switch and vibration collection unit into a single integrated structure, where the switch is disposed on the same housing that contains the vibration collection unit. This merging eliminates the need for separate control mechanisms and simplifies the overall device structure while maintaining ease of operation.
Solution Approach 2:
The housing serves multiple functions: it protects the internal components, provides the contact surface for bone conduction, and houses the switch mechanism. This multi-functionality reduces the number of separate components needed, thereby simplifying the device structure while maintaining operational ease.
2Reliability
If separate surfaces are used for contact and switching, then the functions are distinct, but the operation becomes cumbersome
Solution Approach 1:
The patent merges the contact surface and switch activation surface into a single integrated surface on the housing. This allows the user to perform both contact and switching operations through a single action of pressing the same surface, eliminating the need for separate surfaces and reducing operational complexity.
Solution Approach 2:
The same surface that receives the bone conduction contact also serves as the switch activation surface. When the user presses the housing against their body, the same pressing action automatically activates the switch, making the system self-activating and eliminating the need for separate control operations.

AI summary
A bone conduction microphone is configured to convert vocal cord vibration into a sound signal. The bone conduction microphone includes a vibration collection unit configured to come into contact with a human body and collect vibration in a predetermined direction, which is included in the vocal cord vibration, and a switch configured to switch whether collection of the vibration in the predetermined direction is enabled. The switch is disposed on a side of the vibration collection unit, which is opposite to a side configured to come into contact with the human body, to allow a direction of an operation of switching whether collection of the vibration in the predetermined direction is enabled to be parallel to the predetermined direction.
