Abstract

A wireless speaker assembly is disclosed. The wireless speaker assembly comprises a housing and an electrical plug comprising one or more prongs, where those one or more prongs can be disposed within the housing. The wireless speaker assembly further comprises an AC adapter interconnected to the electrical plug, where that AC adapter can convert AC power to DC power. The wireless speaker assembly further comprises a receiver circuit disposed within the housing and an interconnected antenna disposed within said housing, where the antenna in combination with the receiver circuit can receive Bluetooth compliant wireless signals. The wireless speaker assembly further comprises at least one speaker disposed within the housing, where the at least one speaker receives an audio signal produced by the receiver circuit. Applicant'"'"'s wireless speaker assembly does not comprise any wires or cables extending outwardly from the housing.

Claims

1. A wireless speaker assembly, comprising:

a housing;

an electrical plug comprising one or more prongs, wherein said one or more prongs can be stored within said housing;

an AC adapter interconnected to said electrical plug, wherein said AC adapter converts AC power to DC power;
