Microphones TRIZ Cases
- Helmet Strap Holder for Wireless Communication Device
An adjustable anchor secures a wireless device to helmet straps while a deformable duct allows speaker positioning.
- Embedded FM Antenna in Hearing Protection Muff
Embedding a shortened metal antenna inside the plastic muff housing eliminates whip antenna obstruction risks while maintaining effective FM reception.
- MEMS Backplate Depression for Stress Relief
Segmenting the backplate with a depression alleviates torsional movements and minimizes cracking risks from thermal expansion differences.
- Multipath Digital Microphone With Adjustable ADCs
A multipath digital microphone system uses adjustable analog-to-digital converters to manage signal paths and power states.
- Binaural Hearing Aid Signal Delay Reduction via Segmented Processing
Segmented signal processing reduces binaural hearing aid delay to 13 ms, maintaining tactile-acoustic coupling and resolving time offset issues.
- Loudspeaker Box Arrangement With Integrated Guide Grooves
A loudspeaker box arrangement uses guide grooves and bases to mechanically stack units while establishing electrical contacts.
- Shallow Profile Compression Driver Phasing Plug Design
Eliminating the redundant adapter housing, this design reduces distortion by managing nonlinear air compression through optimized diaphragm positioning.
- Body-Worn Vibration System for Low-Frequency Audio Perception
A body-worn vibration system applies mechanical energy to the pectoralis major muscle to enhance audio perception.
- Triple-Membrane MEMS Device for Enhanced Noise Reduction
Triple-membrane MEMS device resolves ASIC noise and insufficient capacity by segmenting sensing across three membranes with a sealed low-pressure chamber.
