Microphone and SIM Tray Hole Sharing for Cleaner Device Housings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Microphone holes in electronic device housings detract from the aesthetic appearance.
Innovation Solution
A single hole in the housing or tray of an electronic device serves both as a microphone hole and a pin hole for separating a tray from a socket, allowing sound to be introduced to the microphone while maintaining device aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a separate microphone hole is provided in the housing, then sound transmission function is ensured, but aesthetic appearance deteriorates
Solution Approach 1:
The patent combines the microphone hole and tray separation hole into a single hole structure. The housing includes one hole that serves dual purposes: allowing sound to reach the microphone and enabling pin insertion to separate the tray from the socket. This merging eliminates the need for separate holes, thereby improving aesthetic appearance while maintaining both functions.
Solution Approach 2:
The single hole in the housing performs multiple functions simultaneously. It acts as both a sound intake pathway for the microphone and a pin insertion hole for tray separation. This multi-functionality reduces the total number of openings in the housing, addressing the aesthetic concern while preserving operational requirements.
2Object-affected harmful factors
If a single hole is used for both microphone and tray separation, then aesthetic appearance is improved, but structural complexity increases
Solution Approach 1:
The patent introduces a passage structure that segments the functional pathways within the single hole. The passage structure includes a sound passage for acoustic waves and a pin passage for mechanical separation, allowing distinct functions to coexist within one opening. This segmentation manages internal complexity while maintaining external simplicity.
Solution Approach 2:
The passage structure acts as an intermediary element within the single hole, organizing and directing different types of inputs (sound waves and pins) to their respective destinations. By introducing this intermediary structure, the patent manages the complexity of having multiple functions share one opening without compromising the aesthetic benefit.

AI summary
An electronic device is provided. The electronic device includes a housing configured to form at least a portion of an exterior appearance of the electronic device, a socket accommodated in the housing corresponding to a tray hole formed in the housing, a tray inserted into the socket through the tray hole and configured to support an external storage medium, a microphone accommodated in the housing, and a hole (H1) formed in the housing or the tray, wherein, when a pin is inserted through the hole (H1), the tray is separated from the socket, and wherein a sound from the outside of the electronic device is introduced through the hole (H1) to be transmitted to the microphone.
