Abstract
The speaker includes at least one radiating surface (7a/7b) configured to vibrate to produce sound waves. The radiating surfaces are adapted to fit over an existing speaker (2) and are held by flexible suspension elements (8,9) to create a substantially sealed cavity between the existing speaker diaphragm (3) and the radiating surfaces (7a/7b). The radiating surface is firstly supported by a housing adapter (5). Also, a support element (6) is connected between the driven speaker cone and the inner radiating surface (7b) for support and to provide additional sound wave pathway to the radiating surfaces.
