The present invention is generally directed toward the field of accessories for portable electronic devices. More particularly, an embodiment of the present invention is directed toward an accessory for a digital music player that is adapted be mounted in an auxiliary power outlet and has controls for the digital music player on the accessory body.
Many digital music players, such as MP3 players, use 12-volt auxiliary power adapters for charging the player while in the car. The adapter is inserted in the 12-volt car outlet and is plugged into the player through its docking port or input connector to charge the player's battery. The user may place the player in the passenger seat or a holder and listen to music while the player charges. However, if the listener wants to skip a song or pause the player, the listener must locate the player and manipulate its controls. Unfortunately, digital music players are often very small and have small control knobs that are difficult to operate when driving a car. Therefore, what is needed is a new way to control a digital music player when charging it in your car.
An embodiment of the present invention is directed toward a charger for a digital music player. The charger includes a charger body having a set of controls whereby a user can manipulate a function of the digital music player by using the set of controls. The charger body is adapted to fit in a 12-volt car outlet and the controls are positioned on an end face of the charger body. A function code memory in the charger contains the codes required to control the digital music player. The charger preferably has controls that allow a user to pause, play, rewind, or skip songs played by the digital music player. The charger is coupled to the digital music player through a cable and accessory port connector. A transmitter may be provided in the charger body that broadcasts a signal received from the digital music player to a remote receiver.
Another embodiment of the present invention is directed toward an accessory for a portable electronic device. The accessory includes an interface whereby the accessory can transfer control codes to the portable electronic device in response to a user input on the accessory such that a user can implement functions on the portable electronic device with the controls on the accessory. Preferably, the accessory communicates with operating software of the portable electronic device such that the accessory can control the functions of the portable electronic device. The accessory is adapted to fit in a 12-volt car outlet and the controls are positioned on an end face of the charger so as to be accessible to the driver and passengers of the car. The accessory may be directly coupled to the portable electronic device through a cable or wirelessly through an RF transceiver. The accessory may also include a microphone such that a voice signal can be received with the microphone and stored on the portable electronic device
Yet another embodiment of the present invention is directed toward a method of controlling a portable electronic device, such as a digital music player, with a charger. In accordance with the method, a set of user inputs is provided on the charger. Control codes are transferred from the charger to the portable electronic device in response to manipulation of the user inputs such that a function of the portable electronic device is controlled by the user inputs on the charger. The control codes also enable the charger to modify a display of the electronic device. An audio signal is received from the portable electronic device with the charger and the audio signal is transmitted from the charger to a remote receiver.

In an alternative embodiment, the charger may include a transmitter for transmitting a signal received from the electronic device over the cable 6 to a remote receiver. For example, an FM transmitter can be included such that an audio signal received by the charger 2 from a digital music player can be broadcast from the charger 2 to the car radio. In such an embodiment, the controls for the transmitter are also placed on the top of the body portion 4 of the charger along with the controls 10 for the digital music player.
Referring now to
In an alternative embodiment, the charger 20 may include a microphone 42 for detecting sound waves and producing an output signal based thereon. The output signal of the microphone 42 may be sampled by the microprocessor 26 to produce a digital data file which is transferred to the electronic device 24, or the analog signal from the microphone 42 may be provided directly to the device 24 itself depending upon the device's capabilities and the interface available. The device 24 then stores the data file in device memory for later retrieval. When so equipped, the charger 20 can then function as a voice recorder.
In yet another alternative embodiment, the charging accessory 20 includes a transmitter 44 that allows the accessory 20 to broadcast an audio signal received from the device 24 to a remote receiver such as a car radio. In such an embodiment, the transmitter 20 receives an output audio signal from the portable electronic device 24 and broadcast the signal to a remote receiver such that the output signal from the portable electronic device 24 is transferred to the remote receiver. The controls 22 on the accessory 20 are then used to control the music playing on the remote receiver.
In yet another embodiment, a transmitter 44 in the accessory can be used to establish a communication link with a receiver 43 in the device 24. The control codes can then be transmitted wirelessly from the accessory 20 to the device 24. However, as will be appreciated by those skilled in the art, if the device 24 and accessory 20 are not directly coupled, the accessory 20 will not be able to charge the device 24. In addition, the device 24 must be equipped with a receiver 43 to wirelessly receive data.
