Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-screen terminals experience sound field cancellation when multiple loudspeakers are playing sound simultaneously, leading to a poor user experience due to the lack of effective audio optimization across multiple displays.
Innovation Solution
A method that detects the opening/closing angles between display screens and selects prestored audio drive parameters, including filter, gain, and phase parameters, to optimize sound output, thereby minimizing sound field cancellation by calculating similarities between current and prestored angles to match optimal audio settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple loudspeakers on display screens are used for sound output simultaneously, then the sound coverage and functionality are improved, but sound field cancellation occurs resulting in poor audio effect
Solution Approach 1:
The patent changes acoustic parameters (phase, amplitude, frequency) of the sound signals output by multiple loudspeakers based on the relative positional relationships between display screens. By dynamically adjusting these parameters according to the geometric configuration, the system optimizes sound field distribution and prevents cancellation effects while maintaining multi-screen sound coverage.
2Reliability
If audio optimization algorithms are used to improve auditory experience, then the audio effect is enhanced, but the device complexity increases
Solution Approach 1:
The patent applies different audio processing strategies to different local regions or configurations. Based on the relative positional relationships between specific display screens, the system selectively adjusts audio parameters for specific loudspeaker combinations rather than applying a uniform complex algorithm to all speakers, thereby reducing overall system complexity while maintaining audio quality.

AI summary
Disclosed are a method for playing sound and a multi-screen terminal. The method includes: detecting, by a multi-screen terminal, a current opening/closing angle or angles between the respective display screens; and selecting, by the multi-screen terminal according to the detected current opening/closing angle or angles between the respective display screens, a group of prestored audio drive parameters, and outputting the group of audio drive parameters to a power amplification module of the multi-screen terminal; or, determining whether the current opening/closing angle or angles between the respective display screens and the current audio drive parameters are respectively prestored opening/closing angle or angles and audio drive parameters corresponding to an optimal sound field playing effect, and if not, giving a prompt as to whether to adjust the opening/closing angle or angles between the respective display screens and/or the current audio drive parameters. According to the present disclosure, by means of prestoring correspondence relationships among the opening/closing angles, the audio drive parameters and the sound field playing effects, the problem of sound field cancellation of multiple loudspeakers of a multi-screen terminal is solved, the audio effect of the multi-screen terminal is optimized, and the auditory experience of a user is thus improved.
