Earpiece/Earphone Attachments TRIZ Cases
- Microphone Detection Circuit Using Digital Audio Threshold Analysis
A microphone detection circuit uses an analog-to-digital conversion unit to generate digital audio signals for external device analysis.
- Wearable Device State Detection via Multi-Device Acceleration Data Sharing
A wearable information processing system shares acceleration data between devices to determine facing positions and detect attached states.
- Speaker Module With Common Acoustic Spout For IEMs
Merging multiple receiver outputs into one common sound tube simplifies sealing and mounting complexity while maintaining high sound pressure.
- Audio Forwarding Device Wireless Streaming Private Listening
An audio forwarding device streams synchronized digital audio to mobile devices via wireless connections for private listening.
- HRIR Filter Extraction for Low-Capacity Sound Localization
Extracting interaural time and level differences from HRIR data reduces filter coefficients, enabling accurate sound localization on low-performance processors.
