A Novel Design for a Gel-Type DML Transducer Incorporating a Solid Panel Projecting Multiple Independent Sound Sources

Document Thumbnail

The gel-type DML transducer (referred to as the gel transducer in this paper) excites a panel to radiate sound waves through the gel surround. The panel breaks into different characteristic modes of vibration as frequency increases. At high frequencies above 1,600Hz, the extent of the moving area of the panel begins to reduce and becomes localised on the position of the gel transducer. This results in both the sound radiating area and volume velocity being reduced so that the directivity of the sound field narrows. As a result, a single panel with the two gel transducers attached can radiate independent sound sources with minimal acoustic cancellations at high frequencies. The current paper reports on this effect using theoretical and practical approaches.
