Helmet Audio Mixing for Two-Wheeler Navigation and Mobile Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric vehicle navigation systems and helmets with Bluetooth headsets cannot simultaneously receive and play audio information from a terminal device and navigation voice without causing interference, affecting user experience.
Innovation Solution
An audio information transmission system that includes a media control apparatus and an audio switching apparatus in the two-wheled vehicle, which establishes connections with both the mobile terminal and helmet, mixes audio information from the terminal and vehicle, and transmits it to the helmet, allowing for prioritization and volume control of different audio types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the Bluetooth headset in the helmet receives audio information from both the terminal device and the electric vehicle simultaneously, then the user can access both audio sources, but the audio information and navigation voice interfere with each other
Solution Approach 1:
The patent introduces a media control apparatus as an intermediary between the audio sources (terminal device and electric vehicle) and the playback device (headset). This mediator receives audio information from multiple sources, processes them separately, and manages their output to prevent interference. The media control apparatus acts as a buffer and coordinator that enables multi-source audio reception without direct conflict between sources.
2Productivity
If the system forces simultaneous playback of audio information and navigation voice, then both can be heard, but user experience deteriorates due to interference
Solution Approach 1:
The patent implements dynamic audio routing and volume control that adapts to different scenarios. The system can dynamically switch between different audio sources, adjust volume levels of each source independently, and change playback modes based on the current situation. This dynamic control allows the system to optimize user experience by preventing interference while maintaining the ability to deliver both audio information and navigation voice when needed.

AI summary
Disclosed are an audio information transmission system, method, and apparatus, and a corresponding two-wheeled vehicle and helmet. The system includes a media control apparatus and an audio switching apparatus connected to the media control apparatus. The audio switching apparatus is connected to a mobile terminal and the helmet and is configured to receive first audio information transmitted by the mobile terminal and transmit same to the media control apparatus. The media control apparatus is configured to receive and mix second audio information generated by the two-wheeled vehicle with the first audio information, to generate mixed audio information. The audio switching apparatus transmits the mixed audio information to the helmet. In the present application, the audio information transmitted by the mobile terminal and information such as navigation voices, alarms emitted by the two-wheeled vehicle are mixed. The mixed audio information is transmitted to the helmet, so that the user can obtain both the audio information transmitted by the user terminal and the navigation voices transmitted by the electric vehicle, without switching between the audio information from the mobile terminal and the navigation voices emitted by the electric vehicle. The user's driving safety is improved and the user experience is enhanced.
