Audio player device for synchronous playback of audio signals with a compatible device

A method for the shared enjoyment of music between a first audio player device and at least one second audio player device, comprising:

• playing audio signals on the first audio player device while wirelessly transmitting synchronization signals from the first audio player device to the at least one second audio player device;
• and
• receiving the synchronization signals by the at least one second audio player device, wherein the synchronization signals enable the audio signals on the at least one second player device to be played synchronously with the playing of the audio signals on the first audio player device;
• wherein, the first and the at least one second audio player devices are mobile.

A method for synchronously playing an audio signal on a first mobile audio player synchronously with the same audio signal on a second mobile audio player, comprising:

• storing the audio signal on an audio media on the first audio player;
• transmitting the audio signal from the audio media of the first mobile audio player, the transmission having a time period of transmission;
• receiving the audio signal transmitted from the first mobile audio player on an input port of the second audio player;
• playing the received audio signal on an audio output of the second audio player with a delay between the input port and the audio output port of the second audio player, the playing having a playing time;
• transferring the audio signal from the audio media to the audio output of the first audio player with a delay between the audio media and the audio output.

A mobile audio player device enabled to play an audio signal synchronously with a compatible mobile audio player, comprising:

• means for storing the audio signal on an audio media;
• means for transmitting the audio signal from the audio media;
• means for receiving an audio signal transmitted from a compatible mobile audio player;
• means for playing the received audio signal;
• a delay means to synchronize playing of the received audio signal between the mobile audio player and the compatible mobile audio player.

An audio player device for synchronous playing of audio signals with a plurality of compatible devices, comprising:

• a base electronic product selected from the group consisting of a telephone, a portable audio device, an MP3 player, and a portable digital assistant;
• a unit directly integrated with the base electronic product, for enabling wireless transmission and reception of an audio signal for shared listening between a plurality of compatible devices, the unit further comprising:
• a player for playing an audio signal, the audio player further comprising a storage unit for storing the audio signal;
• an interunit transmitter/receiver for transmitting the audio signal from the storage unit and for receiving an audio signal transmitted from another audio player;
• a controller unit for preparing the audio signals for the interunit transmitter/receiver for transmission to another audio player and for preparing the audio signals from the interunit transmitter/receiver received from another audio player;
• a delay that delays the audio signal from playing on the player;
• wherein, the delay enables the audio signal to be played synchronously on the audio player, wherein the audio signal is received by the receiver, and on the other audio player, wherein the audio signal is obtained from storage.

A method for simultaneously playing an audio signal between a first portable audio player and a second portable audio player, comprising:

• transmitting the audio signal from the first audio player to the second audio player;
• playing the audio signal on the first audio player;
• introducing a first delay between the transmitting and the playing;
• sending a second delay from the first audio player to the second audio player;
• playing the audio signal received from the first audio player on the second audio player;
• and
• introducing a second delay on the second audio player so that the playing on the first audio player and the playing on the second audio player occur roughly simultaneously.

A first portable audio player for roughly simultaneously playing an audio signal with a second portable audio player, comprising:

• means for transmitting the audio signal from the first audio player to the second audio player;
• means for playing the audio signal on the first audio player;
• means for introducing a first delay between the transmitting and the playing;
• means for sending a second delay from the first audio player to the second audio player, wherein the second delay enables the first and second audio players to listen to the audio signal transmitted by the first audio player roughly simultaneously;
• and
• means for receiving a second delay on the first audio player from the second audio player for playing received audio signals on the first audio player simultaneously with the second audio player, wherein the second audio player sent the signal to the first audio player.

A method for a first mobile audio player to play an audio signal that is present on the first mobile audio player synchronously with the same audio signal on a second mobile audio player, comprising:

• establishing whether the audio signal is present on the second audio player;
• sending a synchronization signal from the first audio player to the second audio player;
• and
• using the synchronization signal to play the audio signal synchronously on the first audio player and the second audio player.

A method for playing an audio signal on a first mobile audio player on a second mobile audio player in the presence of a rebroadcaster, comprising:

• playing the audio signal on the first audio player;
• broadcasting the audio from the first audio player;
• receiving the audio signal on the rebroadcaster from the first audio player;
• rebroadcasting the received audio signal from the rebroadcaster;
• receiving the rebroadcast audio signal on the second audio player from the rebroadcaster;
• and
• playing the audio signal on the second audio player with the first audio player.

A system for playing an audio signal synchronously on a first mobile audio player and a second mobile audio player, comprising:

• a transmitter on the first player from which the audio signal is transmitted to the second player;
• a delay that is transmitted by the transmitter that comprises the delay from the time of reception to the time of playing on the second player;
• an input port on the second player for receiving the audio signal and the delay transmitted from the first player;
• an audio output on the second player for playing the audio signal with the delay from the time of inputting the audio signal at the input port of the second player;
• wherein an audio output on the first player and the audio output on the second player play the audio signal synchronously.
