Abstract
A hanging planter pot speaker enclosure for stereo or monaural music systems comprising a hollow ceramic housing enclosed on all sides and having openings at the top and bottom. A planter pot is set down into the top opening of the housing, and has a radially outwardly extending flange around its top edge that seats on the marginal edge of the top opening to support the pot, while at the same time forming a seal that closes the top opening. Mounted within the housing below the planter pot is a cone-type speaker that faces downwardly so that sound radiating from the speaker is projected downwardly through the bottom opening. The speaker is sealed to the inner wall of the housing around its entire periphery, so that the space within the housing between the speaker and the pot is entirely sealed. Air contained within this sealed space serves as a pneumatic spring, backing up the speaker cone to improve its response. Suspended below the bottom opening of the housing is a horizontal diffuser, that deflects the sound from the speaker horizontally outward in all directions.
