An electronic speaker, comprising: a device housing defining an interior cavity and including an exterior sidewall extending around the interior cavity between an upper portion and a lower portion of the device housing; first and second sound channels formed at opposing locations along the exterior sidewall, each of the first and second sound channels comprising a plurality of openings formed through the exterior sidewall; a passive radiator array comprising first and second passive radiators (910a, 910b) disposed within the interior cavity, spaced apart from each other in an opposing relationship and aligned to project sound through the first and second sound channels; an active driver disposed in the device housing and configured to generate sound in response to an electrical signal, the active driver comprising driver housing disposed at least partially between the first and second passive radiators, a magnet disposed within the driver housing, a voice coil and a diaphragm facing downwards towards the lower surface of the device housing; and an annular sound channel disposed along the lower portion of the device housing adjacent to the diaphragm of the active driver, the electronic speaker being characterised in that each of the first and second passive radiators comprises: a frame having an annular outer rim extending fully around an outer periphery of the frame and first and second connection members protruding from opposing ends of the outer rim; a rigid diaphragm disposed within a central portion of the frame; a primary annular suspension coupling the diaphragm to the annular outer rim of the frame in a manner that allows the diaphragm to move within the frame; a radiator mass element having first and second opposing ends and a central section extending along a length of the radiator mass element between the first and second opposing ends, wherein a width of each of the first and second opposing ends is greater than a width of the central section; and a secondary suspension coupling the radiator mass element to the frame in a manner that allows the radiator mass to move within the frame, the secondary suspension comprising a first spider element coupled between the first connection member of the frame and the first end of the radiator mass, and a second spider element coupled between the second connection end of the frame and the second end of the radiator mass. a device housing defining an interior cavity and including an exterior sidewall extending around the interior cavity between an upper portion and a lower portion of the device housing; first and second sound channels formed at opposing locations along the exterior sidewall, each of the first and second sound channels comprising a plurality of openings formed through the exterior sidewall; a passive radiator array comprising first and second passive radiators (910a, 910b) disposed within the interior cavity, spaced apart from each other in an opposing relationship and aligned to project sound through the first and second sound channels; an active driver disposed in the device housing and configured to generate sound in response to an electrical signal, the active driver comprising driver housing disposed at least partially between the first and second passive radiators, a magnet disposed within the driver housing, a voice coil and a diaphragm facing downwards towards the lower surface of the device housing; and an annular sound channel disposed along the lower portion of the device housing adjacent to the diaphragm of the active driver, a frame having an annular outer rim extending fully around an outer periphery of the frame and first and second connection members protruding from opposing ends of the outer rim; a rigid diaphragm disposed within a central portion of the frame; a primary annular suspension coupling the diaphragm to the annular outer rim of the frame in a manner that allows the diaphragm to move within the frame; a radiator mass element having first and second opposing ends and a central section extending along a length of the radiator mass element between the first and second opposing ends, wherein a width of each of the first and second opposing ends is greater than a width of the central section; and a secondary suspension coupling the radiator mass element to the frame in a manner that allows the radiator mass to move within the frame, the secondary suspension comprising a first spider element coupled between the first connection member of the frame and the first end of the radiator mass, and a second spider element coupled between the second connection end of the frame and the second end of the radiator mass.
