Host Satellite Speaker Network for Expanded Audio Coverage
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 effective coverage and immersive soundscapes.
Innovation Solution
A portable wireless sound system comprising a host speaker connected to a source device and satellite speakers that can connect and recognize each other, allowing for broadcasting of audio data between speakers without external software, enabling multiple speakers to form a network for expanded coverage and independent channel control.
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 playback function into multiple independent speaker units that can be distributed throughout the space. Each speaker is a self-contained module with its own audio processing capabilities, allowing the system to cover larger areas by simply adding more units rather than using a single complex system.
Solution Approach 2:
Multiple satellite speakers are merged into a unified network controlled by a single host speaker. The host speaker receives audio data from the source device and broadcasts it to all satellite speakers, creating a coordinated multi-speaker system that acts as one unified audio output solution, simplifying the overall system architecture.
2Ease of operation
If Bluetooth is used to receive audio data from source device, then wireless connectivity is achieved, but sound clarity and volume over larger areas deteriorates
Solution Approach 1:
The host speaker acts as an intermediary between the source device and satellite speakers. It receives audio data via Bluetooth from the source device, processes and amplifies the signal, then broadcasts it wirelessly to multiple satellite speakers. This intermediary approach allows satellite speakers to receive high-quality audio signals without each needing a direct Bluetooth connection to the source device.
Solution Approach 2:
The host speaker creates copies of the audio data signal and distributes them to multiple satellite speakers. Each satellite speaker receives an identical copy of the audio signal from the host, ensuring consistent sound quality across all speakers in the network without requiring direct connections to the source device.
3Adaptability or versatility
If satellite speakers receive audio data from host speaker, then system scalability is improved, but power management complexity increases
Solution Approach 1:
Each speaker in the system is designed with universal functionality to operate in multiple roles. Speakers can function as host or satellite depending on their connection status to the source device. This multi-functionality allows the system to scale flexibly by simply adding or removing speakers without requiring different hardware configurations or complex power management schemes.
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.
