Retractable Speaker Module for Slim Portable Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable terminals face challenges in achieving high-quality sound output due to integral speaker designs that compromise sound quality and aesthetics, and separate speaker setups that increase device thickness and hinder slimming trends.
Innovation Solution
A retractable speaker module is slidably integrated into the body housing, allowing for retraction during calls to maintain aesthetics and slimness, and extraction during multimedia use to enhance sound quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the speaker is integrally formed in the receiving hole, then the device structure is simplified, but the sound quality deteriorates
Solution Approach 1:
The speaker is separated from the receiving hole structure into an independent speaker module that can move relative to the body housing. This segmentation allows the speaker to be extracted for high-quality sound output during multimedia playback while maintaining a clean, simple appearance when retracted during calls.
Solution Approach 2:
The speaker module is designed to be movable rather than fixed, allowing it to transition between retracted and extracted states. This dynamic configuration enables the device to adapt its structure based on operational mode - simplified during calls and optimized for sound quality during multimedia playback.
2Manufacturing precision
If the speaker is provided separately from the receiver, then the sound quality improves, but the installation space increases
Solution Approach 1:
The speaker module is nested within the body housing when not in use, utilizing the existing internal space efficiently. The guide rails and moving member system allow the speaker to be compactly stored within the device body, avoiding the need for additional external space while maintaining the ability to extract it for high-quality sound output.
3Manufacturing precision
If the speaker is provided separately from the receiver, then the sound quality improves, but the device thickness increases
Solution Approach 1:
The speaker module transitions from a static separate component to a dynamic movable component that can be retracted into the device body. This dynamic design allows the speaker to be stored within the existing thickness envelope during calls, maintaining a slim profile, while extracting to provide high-quality sound output during multimedia playback.

AI summary
A portable terminal with a speaker device includes a body housing, and a speaker module provided in the body housing and slidably retracted or extracted into/from the body housing. The speaker module includes a speaker housing slidably settled in the body housing, guide rails provided in the body housing, for sliding the speaker housing, at least one guide protrusion provided on the speaker housing and slidably engaged with the guide rails, and a moving member protruding from the speaker housing to an outside of the body housing, for retracting or extracting the speaker housing into/from the body housing.
