Abstract: A speaker apparatus, method, and system with a user selectably expandable chamber is provided. The chamber in its expanded state enhances the speaker's acoustical properties using a relatively stiff back plate of the speaker apparatus. The chamber in its collapsed state provides a thin profile for increased portability or low profile mounted solutions. The speaker is compatible with current electronics and may magnetically attach to a target surface such as a surface of a handheld device. The target surface may effectively supplement the stiffness of the back plate.
