Shared Acoustic Passage for Speaker and Sensor Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The spatial limitations of electronic devices make it difficult to optimize the performance of both speakers and sensors, as separate passages for sound discharge and medium introduction restrict the size of these openings, hindering efficient sound output and environmental sensing.
Innovation Solution
An electronic device design featuring a common passage portion that allows both sound output from the speaker and medium introduction to the sensor, optimizing the use of space and enhancing performance by integrating these functions into a single passage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate passages are provided for speaker sound discharge and sensor medium introduction, then each component can function independently, but the spatial size of the passages is restricted and performance cannot be optimized
Solution Approach 1:
The patent combines the speaker discharge passage and sensor introduction passage into a single integrated passage structure. The passage is configured with a first portion connected to the speaker and a second portion connected to the sensor, allowing both functions to share the same physical space. This merging resolves the spatial limitation by eliminating the need for separate passages, thereby optimizing the use of available space while maintaining both functions.
Solution Approach 2:
The passage is designed to serve multiple functions simultaneously: it acts as both a discharge pathway for speaker sound and an introduction pathway for sensor medium. This multi-functionality is achieved by configuring the passage with appropriate connectivity - the first passage portion connects to the speaker for sound discharge, while the second passage portion connects to the sensor for medium introduction. This universal passage structure resolves the contradiction by allowing one component to fulfill both roles that previously required separate components.
2Reliability
If the passage space is expanded to improve sound discharge and medium introduction, then performance of speaker and sensor is enhanced, but the overall device size increases
Solution Approach 1:
By merging the speaker passage and sensor passage into a single integrated structure, the patent achieves expanded effective passage space without proportionally increasing overall device volume. The shared passage allows both functions to benefit from larger dimensions while the integrated design ensures that the volume increase is minimized compared to having two separate passages of equivalent size.
Solution Approach 2:
The passage structure is configured to nest multiple functions within a compact form. The first passage portion and second passage portion are arranged to share common structural space, with the sensor positioned to utilize the passage structure efficiently. This nesting approach allows the passage to provide enhanced space for both sound discharge and medium introduction while keeping the overall device footprint constrained.
