Wireless Microphone System Using Smartphone Audio Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless microphones face issues with audio quality and transmission when connected to remotely hosted applications, particularly due to poor built-in microphones in computing devices and the difficulty in networking smartphones to client applications, leading to compromised audio fidelity and functionality.
Innovation Solution
A wireless microphone system that utilizes a smartphone's built-in microphone to transmit audio directly to a remotely hosted application via cellular or IP networks, processing the audio on a server and returning results to a separate client device without a direct wireless link between the microphone and client device, leveraging the smartphone's high audio quality and ubiquitous presence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional wireless microphone is connected to a remotely hosted application, then the device can access remote processing capabilities, but audio quality deteriorates due to poor built-in microphones in computing devices
Solution Approach 1:
The patent introduces a smartphone as an intermediary device between the wireless microphone and the remotely hosted application. The smartphone's high-quality built-in microphone captures audio, which is then transmitted to the remote application for processing. This mediator resolves the contradiction by providing superior audio capture capabilities while maintaining remote processing access.
2Ease of operation
If a smartphone is networked to a client application, then audio transmission capability is improved, but device complexity increases due to networking requirements
Solution Approach 1:
The smartphone leverages its universal connectivity capabilities (cellular data, Wi-Fi, Bluetooth) to establish network connections with the remotely hosted application. These multi-functional communication interfaces simplify the networking process compared to dedicated audio transmission devices, reducing overall system complexity while maintaining audio transmission capability.
3Adaptability or versatility
If audio is transmitted over network connections, then remote processing is enabled, but transmission efficiency decreases due to network latency and bandwidth limitations
Solution Approach 1:
The system transmits only essential audio data over the network connection, leaving local processing tasks (such as basic audio encoding and format conversion) to be performed on the smartphone or client device. This partial remote processing approach reduces network bandwidth requirements and transmission time, improving overall transmission efficiency while maintaining remote processing capabilities.
Data Source
AI summary
The technology of the present application provides software as a service (SaaS) executing on a server in a cloud or network. The SaaS receives data from a mobile device of a user over the network. The SaaS processes the data and returns the processed data to a client application executing on a client device of the user, which user is the same as the user of the mobile device wherein there is no direct communication link, wireless or wired, between the mobile device and the client device. In one aspect, the technology of the present application provides the mobile device as a smartphone and a microphone application to be executed on the smartphone.
