description The present invention relates to a miniature speaker having at least a first and a second resonance in its frequency response, the miniature speaker comprising a diaphragm for generating sound pressure waves in response to electrical drive signals, one or more sound channels at least partly surrounding a total air volume forming an acoustical mass, and one or more intermediate air volumes being acoustically connected to the one or more sound channels, wherein the acoustical mass provides that the second resonance in the frequency response of the miniature speaker is positioned within an audible range.
