An electronic device has a chassis configured to hold multiple electronic components in a predefined three-dimensional arrangement whereby some of the electronic components are positioned elevationally above, and overlapping, other electronic components. Each electronic component has an external dimension which falls within a tolerance range between a lower acceptable tolerance limit and an upper acceptable tolerance limit. The chassis has form fitting recesses to receive and hold the electronic components. Each chassis recess is undersized relative to the lower acceptable tolerance limit for the external dimension of an associated electronic component, but the chassis has effective compliant qualities to receive and hold an electronic component even if it has an external dimension at the upper acceptable tolerance limit. The electronic components are interconnected by conductive cables. The chassis has patterned cable channels formed therein to hold and guide the cables through predefined locations within the electronic device between the electronic components.

An electronic device includes an electronic component and a chassis to support the electronic component. The electronic device also includes a non-supporting chassis component that is integrally formed along with and as part of the chassis. The non-supporting chassis component is functionally operable in cooperation with the electronic component to enhance performance of the electronic component. In one example, the electronic component is an electronic speaker and the non-supporting chassis component is a resonance chamber positioned adjacent to the speaker to improve the speaker's sound qualities. The chassis and non-supporting chassis component (i.e., the resonance chamber) are integrally formed together via a single injection molding process using expanded polypropylene.
