Abstract: A headphone and method for allowing manually controlled reception of ambient sound by a user. More particularly, the invention relates to a headphone for listening to an audio signal while allowing varying amounts of ambient sound to the user. In one aspect, the headphone comprises a manually-controllable physical characteristic that controls the amount of ambient sound accessible to the user. The physical characteristic can be sound ports that can be opened or closed. In another aspect, the headphone can comprise a microphone receptive of ambient sound, wherein the user can control the proportion of sound that comes from the ambient sound or the audio signal. The microphone can be part of a noise cancellation system.

Abstract: The invention pertains to a modular inter-unit transmitter/receiver for a portable audio device such as an MP3 player, a handheld device for playback of audio signals, a telephone, etc. More particularly, the unit is configured for an audio player device to enable the player device for wireless transmission and reception of audio signals. In one aspect, a communication means connects the modular audio unit to the audio player device. The device further comprises a switch in which a user of the audio player device can select to play audio signals received from an inter-unit transmitter/receiver or from the audio player device. The switch further enables the user to select whether to play the audio signal on the audio player device or to play the audio signal while transmitting the signal to a compatible device.

Abstract: The invention relates to a method and apparatus for controlling access of a mobile audio device to a cluster of compatible devices. More particularly, the invention pertains to a method to establish communications between a portable audio player and one or more audio players within a cluster. By way of example, users can use identifiers and matching to decide whether to accept or reject a requesting audio player to join the cluster. Further, the identifiers may be stored on the audio players for future reference. Also, directional exchange of information can allow a user to visually select members of the cluster. In a further example, a mobile audio device is configured to communicate within a cluster of audio devices. In addition, the broadcasting responsibility can be transferred among members of the group.

Abstract: The present invention discloses a method for distributing music to members of a music sharing group. In one aspect, the method can include identifying a mobile audio player device that introduces a music selection to another mobile audio player device. A signal comprising the music selection, a musical identifier that identifies the music selection and an identifier that identifies the transmitting device is transmitted from a first mobile device to a second mobile device. The second device stores the musical identifier and the identifier of the transmitting device in association with one another. In another aspect, the devices are enabled to connect over a wide area network and use the identifiers to obtain the music selection from a music distributor over the network. In yet another aspect, the transmitting device receives points or other compensation for introducing the music selection to the second device.

Abstract: A system and apparatus for identifying a first mobile device that introduces a music selection to a second mobile device. In one aspect, the first device transmits a music signal to a second device. The music signal comprises a music selection, a music identifier and an identifier of the first device. The second device is enabled to store the identifier of the first device and the music identifier in association with each other. In another aspect, a computerized database is disclosed for the purposes of transacting with the second device, wherein transacting may include storing the music identifier, the first user identifier and the second user identifier in the database, providing a requested music selection to the first user, registering the first user as a broadcaster, awarding points for purchasers of the music selection broadcast by the first user, or storing and providing ratings of devices of a cluster.

Abstract: The present invention discloses a method, system and apparatus for playing an audio signal synchronously on a first mobile audio player and at least a second mobile audio player. More particularly, the invention pertains to an audio player device enabled for wireless transmission and reception of an audio signal. In one aspect, a delay enables the audio signal to be played synchronously on the audio player with a second audio player. In another aspect synchronization signals are used to play the audio signal synchronously on the first audio player and the second audio player.

Abstract: Individuals share music through portable audio devices that synchronously play music by transmitting music signals from one device to the other. Upon request, other individuals can join such a sharing group as a member, and these new members can either be accepted automatically, or through voting by existing group members. So that members of a group can converse, the fraction of ambient sound admitted by the earphones of the portable device can be manually set. In order to enhance the enjoyment of the music, wearable transducers, such as light emitting diodes, respond to signals related to the beat of the music. Signals can be automatically generated, or manually specified, and signals thereafter stored for playback with the music to which it is related. Wearable transducers associated with individuals at a large music event can be set to receive common signals such that the transducers respond in synchrony with one another.

Abstract: A method and apparatus is disclosed for the shared playing of video by a first video player and a second video player. More particularly, the invention relates to a method for playing a video signal on a first portable video player synchronously with the same video signal on a second portable video player. In one aspect, the first portable video player is enabled to transmit video to a second player. The video is played synchronously on both video players, wherein the video is received from another player or from storage on the player. In various further aspects, synchronization signals are used to adjust the position of the video signal playing on the first and second video player, where the video signal is present on both video players.
