  • Patent number: 9158337
    Abstract: A speaker docking station for an iPad has a housing having a seat for supporting the iPad resting thereon in either portrait or landscape position, a dock connector, an operating circuit for processing an audio signal from the iPad via the connector, and two speaker drivers for reproducing sound based on an audio signal from the iPad and processed by the operating circuit. The connector is connected to the operating circuit by a cable extending outside the housing. The seat has a void, e.g., hole or recess, for accommodating the connector when the iPad is supported by and resting on the seat in the portrait position. The cable is of a sufficient length such that the connector will remain in connection with the iPad when the iPad is turned and supported by and resting on the seat in the landscape position.
