Dynamic Sound Channel Switching for Obstructed Speaker Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The ringtone or voice prompt effect in electronic terminals, such as mobile phones, is compromised when the speaker sound holes are covered by external objects, leading to potential missed calls or important notifications.
Innovation Solution
An electronic terminal with a ringtone sound source module, control module, sound channels, sound collection module, and signal processing module that plays a test ringtone signal through multiple channels, collects and processes exterior sound signals to determine the optimal output channel for a prompt ringtone signal, ensuring maximum volume and clarity, and switches to that channel for improved notification delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mobile phone is placed in various states (in hand, on table, in pocket, in handbag), then the mobility and convenience are improved, but the speaker sound holes are easily covered by external objects, worsening the ringtone prompt effect
Solution Approach 1:
The mobile phone is divided into multiple sound output channels (first sound channel and second sound channel), each capable of independent operation. This segmentation allows the system to switch between different sound output paths, ensuring that if one channel is blocked, another can still deliver the ringtone effectively.
Solution Approach 2:
The system dynamically switches between different sound channels based on real-time detection of channel status. The control unit monitors the sound channels and automatically transitions from a blocked channel to an unblocked channel, making the ringtone output adaptive to the current physical state of the device.
2Device complexity
If the speaker sound holes are covered by external objects, then the device structure remains simple, but the ringtone or voice prompt effect deteriorates significantly
Solution Approach 1:
The system employs dynamic channel switching where the control unit detects when a sound channel is blocked and automatically switches to an alternative channel. This dynamic adaptation ensures reliable ringtone delivery without requiring complex structural modifications to the device.
Solution Approach 2:
The system incorporates feedback mechanisms where the sound collection module detects sound signals from each channel, and the control unit processes this feedback to determine channel status. Based on this feedback, the system automatically adjusts by switching to an unblocked channel, ensuring continuous effective ringtone output.

AI summary
The invention discloses an electronic terminal and a ringtone prompt method for the electronic terminal. A control module of the electronic terminal instructs a ringtone sound source module to play a test ringtone signal, and instructs a ringtone channel switch system to switch all sound channels one by one to output the test ringtone signal; a sound collection module collects an exterior sound signal while each channel is outputting the test ringtone signal and feeds it back to a signal processing module; the signal processing module processes the intensity of the test ringtone signal therein; the control module determines the output channel of a prompt ringtone signal according to the processing result of the collected signal, instructs the ringtone channel switch system to switch to the determined output channel, and instructs the ringtone sound source module to play the prompt ringtone signal.
