Abstract
A speaker assembly broadly comprises an inner housing, an outer shell, an input circuit, and a speaker. The inner housing includes outer shell attachment structure and a lower press-fit outer surface and forms a central chamber retaining the input circuit and the speaker. The outer shell includes a primary enclosure and a lower cap. The primary enclosure includes inner housing attachment structure configured to align with and engage the outer shell attachment structure. The primary enclosure is configured to be press-fit to the inner housing via the lower press-fit outer surface of the inner housing. The lower cap encloses a bottom end of the central chamber. The outer shell is interchangeable with other outer shells having different shapes than the outer shell of the speaker assembly.
