Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless speaker systems face issues with interference, limited functionality, and reduced sound fidelity due to one-way transmission, which can lead to unsynchronized audio and increased complexity in setup and error correction.
Innovation Solution
A two-way wireless speaker system that allows speakers to acknowledge audio data packets, enabling bidirectional communication between the audio hub and speakers, reducing error correction needs, and allowing for customization and synchronization of audio signals, as well as integration of multiple data sources and power management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If one-way transmission is used to eliminate wires, then wire-related problems are solved, but interference with cordless telephones and reduced sound fidelity occur
Solution Approach 1:
The patent implements a two-way communication system where speakers send acknowledgment packets back to the audio hub to confirm receipt of audio data. This feedback mechanism enables the system to detect transmission issues and request retransmission, improving reliability while maintaining wireless operation without interfering with other devices.
2Reliability
If one-way transmission with error correction is used, then data reception reliability is improved, but system complexity and redundancy increase
Solution Approach 1:
Instead of using complex one-way error correction coding, the patent employs a simple acknowledgment-based feedback system. The speaker sends a brief acknowledgment packet to confirm successful reception, allowing the audio hub to verify data delivery without requiring extensive redundancy in the original transmission.
3Ease of manufacture
If one-way broadcast transmission is used, then setup is simplified, but synchronization and sound fidelity deteriorate
Solution Approach 1:
The acknowledgment packets provide timing information that allows the audio hub to synchronize audio data transmission with speaker playback. This feedback-based timing synchronization maintains simple setup procedures while achieving precise multi-channel audio synchronization and improved sound fidelity.
4Manufacturing precision
If acknowledgment packets are implemented, then sound fidelity and synchronization are improved, but communication protocol complexity increases
Solution Approach 1:
The patent extracts only the essential feedback element (acknowledgment packet) from complex communication protocols. The acknowledgment contains minimal information needed for synchronization and reliability verification, keeping the protocol simple while achieving improved audio fidelity and synchronization.
Data Source
AI summary
The two-way wireless speaker system of this invention increases sound fidelity by enabling speakers to acknowledge receipt of audio data packets. This provides increased functionality because the audio hub can receive data not only from wired inputs, but also wireless transmission from computer, cell phone, and other sources. Audio hub can use information from speaker to customize/adjust audio signal for each speaker independently, giving better audio quality and synchronization among speakers.
