Claim:
A wearable speaker system comprising: a first housing having a first opening and a second opening; a second housing having a first opening and a second opening; a third housing having a first opening and a second opening; a passive radiator located in said first housing; a first flexible duct having a first end sealing said first opening of said first housing, and a second end sealing said first opening of said second housing; a second flexible duct having a first end sealing said second opening of said first housing, and a second end sealing said first opening of said third housing; a first flexible sleeve enclosing said first flexible duct wherein said first flexible sleeve prevents said first flexible duct from pinching off or collapsing; a second flexible sleeve enclosing said second flexible duct wherein said second flexible sleeve prevents said second flexible duct from pinching off or collapsing; a first active driver sealing said second opening of said second housing wherein acoustic energy from said first active driver is projected to said passive radiator through said first flexible duct; and a second active driver sealing said second opening of said third housing wherein acoustic energy from said second active driver is projected to said passive radiator through said second flexible duct, wherein acoustic energy from said first and second active drivers is summed at said first housing and transferred to said passive radiator.
