Sliding Display Speaker Layout Using Guide-Member Enclosure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In sliding-type electronic devices, arranging speakers is challenging due to the lack of space when a driver is configured to provide sliding movement, making it difficult to accommodate speakers within the housing.
Innovation Solution
Utilizing the inner space of a driver or guide member in the housing as an enclosure for speakers, allowing for the arrangement of stereo speakers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the speaker is fixed at the rear end of the electronic device, then the assembly is simple, but the speaker grille occupies excessive side surface area and affects appearance
Solution Approach 1:
The speaker assembly is made movable relative to the electronic device body through a sliding mechanism. The speaker can be positioned at the rear end when not in use (minimizing grille visibility) and moved to the front end when audio output is needed. This dynamic positioning resolves the contradiction by allowing the speaker grille area to be minimized at the side surface when the speaker is retracted to the rear.
2Area of stationary object
If the speaker is movable between front and rear ends, then the speaker grille area is reduced, but the structure becomes complex
Solution Approach 1:
The driving assembly that moves the speaker between front and rear positions is integrated with the existing vibration motor assembly. The vibration motor serves dual purposes: generating vibrations for the electronic device and providing the driving force to move the speaker assembly. This merging of functions reduces the overall structural complexity despite adding speaker mobility.
Solution Approach 2:
The vibration motor is designed to perform multiple functions: it generates vibrations for the electronic device operation and simultaneously acts as a driving motor to move the speaker assembly between front and rear positions. This multi-functionality reduces the need for separate driving mechanisms, thereby limiting the increase in structural complexity.
3Manufacturing precision
If a separate driving assembly is added to move the speaker, then the speaker positioning is precise, but the device complexity increases
Solution Approach 1:
The driving assembly is merged with the vibration motor assembly, utilizing the existing motor structure and control system. The same motor that generates vibrations for the device also provides the controlled movement for the speaker assembly, achieving precise positioning without requiring a completely separate driving mechanism.
Solution Approach 2:
The vibration motor serves universal purposes by both generating device vibrations and controlling speaker positioning. The control system leverages existing vibration control capabilities to also manage speaker movement, achieving precise positioning while minimizing the increase in overall device complexity.
