Audio applications acoustic transducers having motor providing modulated electromagnetic flux driving free calibrated weight with acoustic phase offsets countering mechanical inertia providing correct medium/low frequency output.

摘要

The sound production system has a free weight (3) driven by a motor (1) creating an electromagnetic flux which is modulated by an audio feed (9). The calibrated weight is tuned so that the acoustic phase offsets the mechanical inertia creating the correct sound density for medium frequency harmonics and low frequency filtering.
