Bone Conduction Hearing Aid Whistle Monitoring and Cutoff Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bone conduction hearing aids with whistle prevention functions are cumbersome to wear and unable to detect and eliminate whistle noise during use, relying solely on external components for protection, leading to unsatisfactory performance and user experience.
Innovation Solution
A bone conduction hearing aid with an integrated whistle monitoring and protection mechanism that includes a whistle sensor connected to a main controller, which can cut off the assistive microphone or headphone to prevent whistle escalation, and uses springs and baffles to block and eliminate the whistle, enhancing usability and extending the device's lifespan.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing bone conduction hearing aids use external components for protection, then the structure is simple, but the whistle detection and elimination capability is insufficient
Solution Approach 1:
The patent integrates the whistle sensor, springs, and baffles into the internal structure of the hearing aid device, merging the protection function with the existing device architecture. The whistle sensor is positioned inside the shell with pickup holes, and the springs and baffles are integrated into the internal structure, eliminating the need for separate external protection components while enhancing whistle detection and elimination capabilities.
2Reliability
If the hearing aid relies on external components for protection, then the device is easier to manufacture, but the performance and user experience are unsatisfactory
Solution Approach 1:
The patent divides the hearing aid into distinct functional modules: the shell with pickup holes, the whistle sensor positioned inside the shell, the springs for protection, and the baffles for whistle elimination. This segmentation allows each component to be manufactured and assembled independently, improving manufacturing feasibility while achieving the desired performance enhancement through integrated design.
3Ease of operation
If the hearing aid cannot detect whistles during use, then the structure is simpler, but the user experience is poor
Solution Approach 1:
The hearing aid device performs self-monitoring of whistle conditions through the integrated whistle sensor that continuously detects whistle frequencies. The system automatically triggers the springs and baffles to eliminate whistles without requiring user intervention, providing seamless user experience while maintaining manageable complexity through automated functionality.
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 whistle monitoring and protection mechanism effectively detects and prevents whistles, ensuring a secure fit and improved sound amplification, while reducing damage to the sensor and providing fall protection, thus enhancing the hearing aid's performance and longevity.
Implementation Method 1
a first spring arranged on an outer wall of the connecting rod, the first spring being fixed to a bottom wall of the sleeve... a second spring mounted to an inner wall of the groove
Implementation Method 2
The reciprocating movements of the first and second springs help reduce damage to the whistle sensor and provides fall protection
Implementation Method 3
The baffle is provided, at a bottom end thereof, with a first spring arranged on the outer wall of the connecting rod... block and eliminate the generated whistle

AI summary
Disclosed is a bone conduction hearing aid with a whistle prevention function, including two shells and a connection part attached to opposing sidewalls of the shells. An upper part of the connection part is arc-shaped. Each shell includes a headphone arranged on an inward-facing side. A partition is horizontally set in the middle of the shell. A power source is arranged on one side of a bottom of the partition. An assistive microphone is located on one side of the power source and extends through to the outside. A main controller is arranged on an opposite side of the bottom of the partition. A whistle monitoring and protection mechanism is located in the middle of the partition to fulfill whistle monitoring during use of the hearing aid. A whistle sensor, upon detecting a whistle, transmits a signal to the main controller to selectively cuts off the assistive microphones or headphones.
