Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices, such as in-ear or ear-hanging hearing aids and headphones, face challenges in miniaturization and lightweight design due to their structural design, which includes a main body with an external housing and internal framework that results in large size and weight.
Innovation Solution
A wearable device design featuring a housing assembly with integrated sound pickup holes and microphone assemblies, utilizing a second fixing structure to maintain coaxial continuity and sealed communication, along with a decentralized installation of functional components within the housing assembly to optimize space utilization and reduce component count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a main body with external housing and internal framework is used to assemble functional components, then the device structure is complete and functional, but the device size becomes large and weight increases
Solution Approach 1:
The patent merges the housing assembly and microphone assembly into a single integrated unit. The housing wall itself forms the sound pickup hole, and the microphone assembly is directly fixed to the inner wall of the housing assembly, eliminating the need for separate connecting parts and reducing overall device weight while maintaining structural completeness
Solution Approach 2:
The housing assembly serves multiple functions: it provides structural support, contains the microphone assembly, and directly forms the sound pickup hole through its wall. This multi-functionality reduces the need for additional components, thereby reducing weight while maintaining ease of manufacture
2Ease of manufacture
If a main body with external housing and internal framework is used to assemble functional components, then the device structure is complete and functional, but the device volume becomes large
Solution Approach 1:
The housing assembly and microphone assembly are merged into one integrated structure, with the microphone assembly directly fixed to the housing inner wall. This eliminates intermediate connecting structures and reduces the overall volume of the device while maintaining structural completeness
Solution Approach 2:
The microphone assembly is nested within the housing assembly, with the sound inlet channel of the microphone assembly sealed to the sound pickup hole formed through the housing wall. This nested arrangement optimizes space utilization and minimizes device volume
3Measurement precision
If the sound inlet channel of the microphone assembly is sealed to the sound pickup hole, then accurate sound signal collection is achieved, but the structural complexity increases
Solution Approach 1:
The sound pickup hole is formed directly through the housing wall, merging the housing structure with the sound pickup function. The microphone assembly is then directly fixed to the housing inner wall with its sound inlet channel sealed to this hole, achieving accurate sound collection while simplifying the overall structure by eliminating separate connecting components
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 design achieves miniaturization and lightweight construction while ensuring accurate sound signal collection and identification, enhancing wearability and aesthetic appeal by fully utilizing the housing assembly's structural space and reducing the need for additional connecting parts.
Implementation Method 1
a sound pickup hole, wherein the sound pickup hole is provided through a housing wall of the housing assembly so that an interior of the housing assembly is connected to an exterior of the housing assembly

AI summary
A wearable device including a housing assembly and a microphone assembly is provided. The housing assembly includes a sound pickup hole connecting the interior of the housing assembly to the exterior of the housing assembly, and the microphone assembly is arranged in the interior of the housing assembly and is fixedly connected to the inner wall of the housing assembly. A sound inlet channel of the microphone assembly is in sealed connection with the sound pickup hole so that the microphone assembly may pick up an external sound signal input via the sound pickup hole. The housing assembly is designated as a structural mounting carrier for the microphone assembly, which reduces the use of related connecting parts, thereby fully utilizing the structural space of the housing assembly and realizing the structural fusion between the housing assembly and the microphone assembly, providing support for the miniaturization, compactness, and lightweight design of the device. At the same time, the sealed connection between the sound pickup hole and the microphone assembly provides a strong guarantee for the microphone assembly to accurately collect and identify external sound signals.
