Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional audio systems face challenges in distributing audio signals over long distances without the need for extensive wired connections, particularly in complex configurations, which can be impractical and aesthetically unpleasing, and require significant reinstallation efforts when relocating.
Innovation Solution
A wireless audio system utilizing a head end and remote endpoints that communicate via wireless protocols like IEEE 802.11 or Bluetooth, processing audio signals with codecs such as AC-3 to transmit them as IP packets, eliminating the need for physical wiring between audio sources and amplifiers/speakers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired connections are used to distribute audio signals, then signal transmission reliability is improved, but installation complexity and aesthetic appearance deteriorate due to exposed wiring
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless communication system. Audio signals are transmitted via wireless protocols (WiFi, Bluetooth, etc.) between the audio source and amplifier/speaker units, eliminating the need for physical audio cables while maintaining signal transmission functionality. This resolves the contradiction by substituting the mechanical wiring infrastructure with electromagnetic wave-based transmission.
Solution Approach 2:
The patent introduces a wireless communication intermediary (wireless network infrastructure, wireless transceivers) to facilitate audio signal transmission between components. Instead of direct wired connections, the wireless intermediary carries audio data packets between the audio source and playback devices, eliminating exposed wiring while ensuring reliable signal delivery through protocol-based communication.
2Productivity
If wired connections are used for multi-channel audio systems, then audio signal distribution is improved, but the quantity of wiring and installation burden increase significantly
Solution Approach 1:
The patent merges multiple separate wired connections into a single wireless communication channel. Instead of requiring individual audio cables for each channel (left, right, center, surround, etc.), the system transmits multi-channel audio data through wireless protocols, consolidating what would be multiple physical connections into wireless signal transmission. This dramatically reduces the quantity of wiring while maintaining multi-channel audio distribution capability.
Solution Approach 2:
The wireless communication infrastructure serves multiple functions simultaneously: it transmits audio signals, provides power delivery (in some implementations), enables device control, and supports multiple channels. This universal wireless interface replaces what would otherwise require separate dedicated wiring for each function and channel, reducing overall wiring quantity while improving distribution efficiency.
3Stability of the object's composition
If audio wiring is installed permanently, then signal transmission stability is improved, but adaptability and relocation flexibility deteriorate
Solution Approach 1:
The patent transitions from a static wired connection system to a dynamic wireless system. The wireless connection allows audio components to be moved, added, or removed without physical reconfiguration of wiring infrastructure. The system dynamically establishes and maintains wireless connections, enabling flexible relocation while maintaining stable signal transmission through continuous wireless communication protocols and automatic connection management.

AI summary
Systems and methods are provided to facilitate the distribution of audio signals over wireless networks. In one implementation, an audio system includes a head end having an encoder and a wireless network interface. Audio signals associated with a plurality of audio channels are processed by the encoder to provide an encoded signal in accordance with an audio codec. The encoded signal can be provided to a wireless network by the wireless network interface as a plurality of data packets associated with a network address in accordance with a wireless networking protocol, such as an IEEE 802.11 protocol. One or more remote endpoints can also be provided to receive the data packets from the wireless network, assemble the data packets to obtain the encoded signal, and extract at least one of the audio signals from the encoded signal in accordance with the audio codec. Multicast and unicast implementations are also provided.
