Abstract
An open back speaker module includes a speaker mounting element having a front face defining at least one sound transducer opening and a rim provided with a first set of electrical contacts, and at least one sound transducer for creating sound waves mounted to the sound transducer opening of the speaker mounting element. The open back speaker module is couplable to a structural element such that the speaker module and the structural element at least partially define a chamber behind the sound transducer. A receptacle or a gasket, couplable to the structural element and adapted to engage or be engaged by the speaker mounting element, may also be provided to help secure the open back speaker module to the structural element. The speaker module, receptacle, and the gasket are preferably flexible such that they may conform to any shaped of structural element. However, the speaker module and/or the receptacle may instead be rigidly formed and pre-shaped to conform to the shape of a specific structural element. Additionally, the front of the speaker mounting element may be provided with a plurality of undulations which increase flexibility and improve the acoustics of the speaker.
