Abstract
A child soothing device includes a frame comprising a structural support, a housing coupled to the structural support and comprising a cover with an opening, and a speaker including a speaker driver and a speaker chamber. The speaker driver has a diaphragm disposed relative to the opening in the cover for external sound wave propagation via displacement of the diaphragm, and the speaker chamber has a volume defined by the housing and in communication with the diaphragm for internal sound wave propagation via the displacement of the diaphragm. The device further includes a partition within the housing to further define the volume of the speaker chamber. The volume may include a region obliquely oriented relative to the diaphragm to support a low frequency response of the speaker.
