Surround Sound via Multi-Phone Wireless Network
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional phones have limited speaker capabilities, making them unsuitable for producing high-quality surround sound due to their limited volume and range.
Innovation Solution
A method and system where multiple cell phones form a wireless network, with one acting as a master device to send and synchronize surround sound signals, dynamically adjusting based on the relative positions of the devices to enhance the surround sound experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple cell phones are used to form a wireless network for surround sound, then the sound range and quality are improved, but the device complexity increases
Solution Approach 1:
The system divides the surround sound functionality into multiple independent cell phones, with one acting as master device and others as slave devices. Each phone handles specific audio channels, segmenting the overall sound reproduction task across multiple devices to achieve enhanced sound range and quality.
Solution Approach 2:
The master device performs multiple functions including sending surround sound signals to slave devices, monitoring their locations, determining suggested locations, and dynamically adjusting audio signals. This multi-functionality consolidates control operations in one device, managing the complexity of the multi-device system.
2Illumination intensity
If multiple cell phones are used to form a wireless network for surround sound, then the sound quality is improved, but the ease of operation deteriorates
Solution Approach 1:
The master device automatically monitors the locations of slave devices and dynamically adjusts audio signals based on their positions. The system provides suggested locations for optimal sound quality, allowing devices to self-configure and optimize without requiring manual user intervention for complex setup procedures.
Solution Approach 2:
The master device continuously monitors the locations of slave devices and uses this feedback to dynamically adjust the surround sound signals. This closed-loop control ensures optimal sound quality is maintained automatically as devices move, eliminating the need for manual reconfiguration.
3Adaptability or versatility
If cell phones move during surround sound playback, then the adaptability is improved, but the stability of sound reproduction deteriorates
Solution Approach 1:
The system dynamically adjusts the surround sound signals based on the real-time locations of the cell phones. The master device continuously monitors device positions and modifies audio signal distribution to maintain stable sound reproduction quality despite device movement, adapting the system configuration as needed.
Solution Approach 2:
The master device monitors the locations of slave devices and uses this location feedback to dynamically adjust audio signals, ensuring stable sound reproduction quality is maintained even as devices move around the space.
Data Source
AI summary
Systems and methods that reproduce surround sound effects from an audio source are described. Wireless communication devices form a wireless network in which music, for example, can be played on the speakers of the wireless communication devices to reproduce surround sound effects from a selected audio source. As the wireless communication devices roam with respect to each other or with respect to a focal point or listening position of the wireless network, the wireless network adjusts how the audio source is played at each speaker of the respective wireless communication device to maintain or to enhance the reproduction of surround sound effects from the audio source.
