Problem

Current wireless audio systems face delays when synchronizing audio with video, and they often restrict the ability to create surround sound or expandable speaker setups due to limitations in wireless communication protocols like Bluetooth.

Innovation Solution

An expandable speaker system with a center module that uses unique identification and mechanical connections to transmit stereo sound components to multiple speakers, allowing for real-time audio broadcasting and easy expansion, utilizing FM radio transmissions and wireless communication bands for efficient pairing and power transfer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If wireless communication protocols like Bluetooth are used to transmit audio, then wireless connectivity is achieved, but audio synchronization delay occurs and expandable surround sound is not supported

Engineering Contradiction:
Improvewireless connectivityVSAvoidaudio synchronization delay
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system segments the audio transmission path by introducing intermediate relay speakers that receive audio from a source speaker and forward it to additional speakers. This segmentation allows the audio signal to be distributed wirelessly across multiple speakers while maintaining synchronization, as each relay speaker receives and retransmits the signal in sequence rather than requiring direct connection from the source to all speakers.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Relay speakers serve as intermediaries in the audio transmission chain. These intermediary devices receive audio signals from the source speaker via wireless communication and then transmit the signal to additional speakers, enabling expandable surround sound configurations while maintaining audio synchronization through the relay mechanism.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If Bluetooth or similar protocols are used, then wireless audio transmission is enabled, but expandable surround sound and multi-speaker configurations are not supported

Engineering Contradiction:
Improvewireless audio transmissionVSAvoidexpandable surround sound capability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The audio system is segmented into a source speaker and multiple relay speakers that can be independently added or removed. Each relay speaker acts as an independent node in the network, allowing the system to be expanded by simply adding more relay speakers without requiring changes to the source speaker or existing connections.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically adapts to different speaker configurations through automatic detection and pairing mechanisms. When relay speakers are added to the environment, the source speaker automatically detects them and establishes wireless connections, enabling the system to dynamically adjust to various surround sound configurations without manual reconfiguration.

Inventive Principle:
Principle #15Dynamics

3Reliability

If mechanical connections are used for speaker assembly, then stable physical connection is achieved, but system expandability and flexibility are reduced

Engineering Contradiction:
Improvephysical connection stabilityVSAvoidsystem expandability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system is divided into modular speaker units that can be independently connected or disconnected. Each speaker maintains stable mechanical connections for power and data transmission while using wireless communication for audio signal transmission, allowing the physical structure to remain stable while the system can be easily expanded by adding or removing individual speaker modules.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each speaker in the system is designed with universal functionality, serving both as a standalone speaker and as a relay node for expanding the system. The mechanical connectors are designed to be universal across all speaker types, allowing any speaker to be connected to any other speaker regardless of its role in the configuration, thereby enabling flexible expansion while maintaining stable physical connections.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

An expandable wireless speaker system and method is disclosed. The speaker system comprises a center module and at least two or more speakers. The center module has a unique identification number and has mechanical connections on at least one side. The center module is configured to receive an external device, wirelessly or directly connected and has a transceiver configured to scan for an unused channel and transmit audio. The speakers each have a mechanical connection on either side to connect to the center module or the other speakers. The two or more speakers are configured to scan the communication spectrum for the center module's unique identification and when the two or more speakers locate the center module's unique identification, the two or more speakers pair with the center module to receive audio. The communication spectrum can be a wireless channel such as 5.8 GHz or the FM radio spectrum.
