  • Patent number: 9002044
    Abstract: Electroacoustical speaker devices that synchronously play audio received from a source. In one embodiment, one speaker acts as the master and the other speaker acts as the slave. The master speaker receives digital audio data from a source and, in addition to playing the digital audio received from the source, the master speaker retransmits the digital audio to the slave speaker. The master speaker additionally sends synchronization data to the slave speaker, such as data that indicates the buffer status or playback position of the master speaker. The slave speaker utilizes the synchronization data from the master speaker to adjust, for example, its buffer status or playback position, so that the two speakers play the audio synchronously (e.g., within thirty milliseconds). In one embodiment, the master speaker uses a connection-oriented protocol, such as TCP/IP, to transmit buffered audio data to the slave speaker and uses a connectionless protocol, such as UDP or ICMP, for the synchronization data.

The system may then suspend rendering of the first audio content at the at least one playback device, and provide the second audio content to be rendered by the at least one playback device for a duration of time. Upon exiting audition mode, either by completion of the second audio content, expiration of the duration of time, or request to exit audition mode, the system may resume rendering of the first audio content by the at least one playback device.

  • Patent number: 8903101
    Abstract: A system for actively reducing noise at a listening point, includes an earphone housing, a transmitting transducer, a receiving transducer and a controller. The transmitting transducer converts a first electric signal into a first acoustic signal, and radiates the first acoustic signal along a first acoustic path having a first transfer characteristic and along a second acoustic path having a second transfer characteristic. The receiving transducer converts the first acoustic signal and ambient noise into a second electrical signal. The controller compensates for the ambient noise by providing a noise reducing electrical signal to the transmitting transducer. The noise reducing electrical signal is derived from a filtered electrical signal that is provided by filtering the second electrical signal with a third transfer characteristic. The second and the third transfer characteristics together model the first transfer characteristic.

  • Patent number: 8879759
    Abstract: Digital musical footwear is disclosed having hidden compartments which house a thin integrated multi-plane electronic circuit board assembly (2) and a rechargeable lithium ion battery pack. A transmitter antenna is attached to a hand held device such as a smart phone which antenna sends wireless short wave sound signals to a receiving antenna part of the circuit board assembly. Multiple mini-speakers (6, 7) are footwear mounted to play the music. Bluetooth® version 4.0 wireless protocol technology is employed in the circuit board assembly. The circuit board can be flat and hidden in a recess of a heel or curved and hidden in a wall recess of the footwear as can the battery pack. Advanced lithium ion batteries such as silicon wafer or silicon core-shell nanowire batteries may be used to reduce battery weight. Flexible flat speakers (65) such as the FleXpeaker® may also be used to further reduce weight.
