Earpiece/Earphone Attachments TRIZ Cases
- Vee Antenna Geometry for 2.4 GHz In-Ear Hearing Aids
By bending a dipole into a 90-degree Vee shape, this case fits 2.4 GHz BLE antenna length into small in-ear hearing aids.
- Cold-Drawn EVA Earplug Cord for Reduced Deformation
Cold drawing an EVA earplug cord raises elastic modulus and limits elongation, improving handling and assembly stability.
