Mobile Terminal Sound Output Destination Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile terminal devices lack an intuitive and user-friendly method for switching the output destination of incoming call sound between the device's internal speaker and a wirelessly connected speaker during a call, often requiring manual operation after the call has started, which can be inconvenient and prone to unintentional settings.
Innovation Solution
The mobile terminal device incorporates a touch-sensitive display with specific regions and icons for guiding the user to select the sound output destination through flick or slide operations on an incoming call screen, allowing seamless switching between internal and wireless speakers without interrupting the call setup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation is required to switch output destination after call starts, then device complexity is reduced, but ease of operation deteriorates
Solution Approach 1:
The patent applies preliminary action by enabling users to select the sound output destination (internal speaker or wireless speaker) during the incoming call screen phase, before the actual call is established. This allows the output destination to be predetermined and automatically applied when the call starts, eliminating the need for manual switching during the call and improving operational ease.
2Ease of operation
If automatic switching to wireless speaker is implemented, then ease of operation is improved, but reliability deteriorates due to unintentional settings
Solution Approach 1:
The patent applies local quality by providing distinct operational regions on the incoming call screen: a first region for selecting the internal speaker and a second region for selecting the wireless speaker. Each region has specific visual indicators and requires intentional user interaction within that localized area, preventing accidental selections and improving reliability while maintaining ease of operation through clear visual guidance.
3Adaptability or versatility
If multiple touch operations are recognized for different functions, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent applies dynamics by implementing a flexible touch operation recognition system that can identify multiple types of user interactions (tap, flick, slide) on the incoming call screen. The system dynamically responds to different touch patterns: a tap operation selects the internal speaker, while a flick or slide operation selects the wireless speaker. This dynamic response mechanism provides adaptability for different user preferences without significantly increasing device complexity.

AI summary
A mobile terminal device is provided with a call control module configured to switch an output destination of receiving sound in a phone call, between a first sound output module provided in the mobile terminal device, and a second sound output module wirelessly connected to the mobile terminal device. The call control module sets the output destination to the first sound output module for starting the phone call, when a first touch operation is performed with respect to a first object included in an incoming call screen displayed on a display surface, and sets the output destination to the second sound output module for starting the phone call, when a second touch operation different from the first touch operation is performed with respect to the first object.
