Improvement of Sound Quality by Means of Ultra-Soft Elastomer for the Gel Type Inertia Driven DML Type Transducer.
Unlike standard DML transducers, the gel-type inertia driven transducer (referred to as the gel transducer in this paper) designed as a mini woofer DML-type transducer, transfers its pistonic movement to a panel through the gel surround, thereby generating a transverse wave. This mechanism induces m...
