Portable Wireless Sound System Host Satellite Audio Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable wireless speakers and subwoofers face limitations in sound clarity and volume over larger areas and distances, necessitating multiple speaker setups for improved soundscapes and coverage.
Innovation Solution
A portable wireless sound system comprising a host speaker connected to a source device and satellite speakers that can connect and broadcast audio data without external software, featuring a 7.4 volt architecture for increased power, additional antennas for extended range, and modes for optimized sound quality and distance, allowing for stereo and long-range audio transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple speakers are set up to cover large areas, then sound coverage area is improved, but device complexity increases
Solution Approach 1:
The system divides the audio output function into multiple independent speaker units, each capable of operating autonomously or in coordination with others. The host speaker handles primary audio processing while satellite speakers provide distributed sound coverage, allowing the system to cover large areas without requiring a single complex device
Solution Approach 2:
Multiple satellite speakers are merged into a coordinated network that operates as a unified audio system. They receive synchronized audio data from the host speaker and play in coordination, creating a distributed sound field that covers large areas while maintaining system simplicity through centralized control
2Ease of operation
If Bluetooth is used for wireless communication between speakers, then ease of operation is improved, but transmission distance is limited
Solution Approach 1:
The host speaker acts as an intermediary device that receives audio from the source via Bluetooth and re-transmits it to satellite speakers. This intermediary approach allows satellite speakers to be positioned farther from the source device while maintaining reliable wireless connection through the host's broadcast capability
Solution Approach 2:
The wireless communication function is segmented into two stages: first, Bluetooth connection from source to host speaker; second, broadcast transmission from host to satellite speakers. This segmentation extends the effective transmission distance by creating a relay communication path
3Power
If 7.4 volt architecture is used, then power output is improved, but energy consumption increases
Solution Approach 1:
The 7.4 volt architecture is applied selectively to specific components that benefit from higher power, such as the amplifier and audio processing circuits, while other components operate at lower voltages. This localized high-power approach improves overall system power output without proportionally increasing total energy consumption
Data Source
AI summary
A portable wireless sound system comprising at least two speakers is provided. A first speaker is determined to be a host speaker by having a wireless connection to a source device, such that the host speaker receives audio data from the connected source device, outputs the audio data signal, and plays audio. One or speakers are determine to be a satellite speaker by not having a connection to a source device, such that the satellite speakers receive audio data from the host speaker and play audio.
