Abstract: The present disclosure provides hearing assistance devices and methods of generating a resonance within hearing assistance devices that use moving coil drivers, e.g., electro-dynamic coil drivers. As small moving coil drivers are typically inefficient within the voice band of frequencies, e.g., above 1 kHz, the hearing assistance devices described herein utilize the resonance of a mass within the hearing assistance device and a compliance of air within the housing of the hearing assistance device or within portions of the acoustic driver housing to aid in amplification of select frequencies within the voice band of human speech, e.g., between 2.5 kHz and 6 kHz. By using the assistance of the resonance created, the moving coil driver utilized does not need to operate as efficiently within the range of resonance frequencies.
