  • Miniature speaker with essentially no acoustical leakage
    Patent number: 11049484
    Abstract: The present invention relates to a miniature speaker comprising front and a rear volume, and one or more moveable diaphragms each comprising one or more cantilever beams, and associated one or more air gaps, arranged between the front and rear volumes, wherein the one or more cantilever beams are configured to bend or deflect in response to an applied drive signal, and wherein the one or more air gaps between the front and rear volumes remain essentially unaffected during bending or deflection of the one or more cantilever beams thus maintaining the acoustical leakage between the front and rear volumes at a minimum. The present invention further relates to a receiver assembly comprising such a miniature speaker, and to a hearing device, such as a receiver-in-canal hearing device, comprising such a receiver assembly.
