The present invention is related to a docking station. More particularly, the present invention is related to a docking station for connecting an electronic device such as a portable digital audio player to an audio system in a vehicle such as a car, a camper, or a boat.
Portable digital media players allow consumers to carry their music and other media with them wherever they go. Devices such as the iPod™ are rapidly gaining popularity. It is also desirable to connect these portable digital audio players to audio systems in vehicles such as cars, campers, or boats. Such a connection will allow music to be played through the speakers for multiple persons to enjoy, rather than through the headphones for one person to hear.
Currently, there are two main options for connecting a portable digital audio player to an audio system in a car, a camper, a boat or other vehicles. Using the first option, a portable digital audio player is connected to the vehicle audio system via a cassette adapter. A cassette-shaped interlace on one end of the adapter inserts into the vehicle audio system's tape deck. A mini-plug on the other end of the adapter inserts into the portable digital audio player's headphone jack. This connection allows the portable digital audio player to connect to the vehicle audio system through the in-dash cassette player. However, this option is problematic. First, the ease in which the connections are able to disconnect forces a user to carefully organize the tangle of cords required to connect the device to the tape player. Next, using this connection degrades the sound coming out of the device since it must be transferred from the device to the tape cassette and then from the cassette to the stereo.
A second option involves connecting a portable digital audio player to the vehicle audio system via a wireless FM transmitter, which allows the portable digital audio player's music to play wirelessly through any FM radio. This connection is also lossy and is subject to normal radio transmission problems such as difficulty in tuning and the inability to receive transmission in certain locations.
Both options require finding placement for the portable digital audio player somewhere in the vehicle, separate from the vehicle audio system. The second option also requires finding placement for the transmitter itself. In vehicles such as cars, campers, or boats, space is at a premium and it is difficult to find space to secure the portable digital audio player and/or the transmitter such that it would not fall or move about as the vehicle is moving. In addition, in a boat, audio systems are often made to be waterproof. The current methods of connecting a portable digital audio player to a vehicle audio system would not give it any protection from the elements, thus making water damage to the portable digital audio player more likely.
The present invention is directed to a docking station, which allows an electronic device such as a portable digital audio player to be secured and protected from the elements while connected to an audio system of a vehicle such as a car, a camper, or a boat; or connected to an audio system in other consumer products. The docking station is enclosed within a housing unit such that when the electronic coupling on the electronic device is coupled to the corresponding electronic coupling in the docking station, the body of the electronic device is enclosed entirely within the housing unit. A cover then seals to the housing unit to define a waterproof enclosure for the electronic device. In some embodiments of the present invention, the housing unit comprises an enclosure to securely hold the electronic device within the housing unit. In some embodiments of the present invention, the cover includes controls for controlling the audio system, including the now connected and enclosed portable digital audio player. In some embodiments of the present invention, the electronic device is controllable with a remote control. In some embodiments, the housing unit further comprises an enclosure having a unique geometry to securely hold the remote control as well as the electronic device.
Further, the invention comprises a housing unit containing a docking station for coupling to an electronic device such as a portable digital audio player. Once the electronic device is securely docked, the cover is able to be moved to a closed position, thus coupling with the housing unit to define a waterproof enclosure for containing the electronic device. In some embodiments of the present invention, an audio system control panel is located on the cover. The cover is able to connect to the housing unit in various ways. In one embodiment, the cover is connected to the bottom of the housing unit such that it must be flipped upwards to the closed position. In an alternative embodiments, the cover is connected to the top of the housing unit such that it flips downwards to the closed position or connected to the side of the housing unit and swings open and closed. In yet another alternative, the cover is completely detachable from the housing unit and must be snapped into place to the closed position. In some embodiments, when the cover is in the closed position, the portable digital audio player is connected and secured within the waterproof housing unit and protected from the elements.
In addition, the audio system and the docking station are connected to the vehicle's engine such that when the engine is turned off and the key removed, a series of beeps will sound to remind the owner that the electronic device is still connected and enclosed within the housing unit. This reminder system helps to prevent the owners from leaving the electronic device in the vehicle unintentionally.
In some embodiments of the present invention, the housing unit 100 is part of an audio system 99 in a vehicle, such as for example a car, a camper, or a boat. In other embodiments of the present invention, the housing unit 100 is a stand alone audio device. In yet other embodiments of the present invention, the housing unit 100 is integrated into common consumer products, appliances or accouterments. Examples of other items in which the housing unit 100 is able to be integrated with include, but are not limited to: barbecue grills or other outdoor kitchen units; hot tubs; refrigerators; furniture; shower and bathroom appliances; bicycles; motorcycle or skiing helmets; backpacks or purses; among others.
A device-housing connector 101 couples with the electronic device connector 151. As shown, the device-housing connector 101 is the male end of connector and the electronic device 150 has a connector 151 which is the female counterpart to the device-housing connector 101. It will be readily apparent to those ordinarily skilled in the art that in alternative embodiments, the device connector 151 is the male end of a connector pairing and that the device-housing connector 101 is the female end of the connector pairing. It will also be apparent to those having ordinary skill in the art, that although the connectors 101 and 151 are shown having a particular geometry and pin layout, any connectors which electrically couple the device 150 with the housing 100 are equally envisioned. In some embodiments of the present invention the electronic coupling means are selected from among: RCA cables, multi-pin connectors, 8P8C connectors, DE-9 connectors, USB connectors, and 30-pin connectors, among others.
To couple the electronic device 150 to the housing unit 100, a user inserts the electronic device 150 through the form fitting opening 103 and completely into the form fitting cavity 102, resulting in the electronic device 150 being fitted entirely within the housing unit 100.
The control interface 105 is coupled to the housing unit 100. As shown, the control interface 105 is attached to the bottom edge of the housing unit 100 and the control interface 105 swings upward to couple with the top edge of the housing unit 100 to define an enclosure for containing the electronic device 150 within the housing device 100. It will be readily apparent to those ordinarily skilled in the art that the control interface 105 is able to couple to the housing unit in a wide variety of ways, including, but not limited to, flip down designs and detachable designs (discussed in
As shown, the control interface 105 is electronically coupled to the housing unit 100 through the interface connector 104 and the controller connector 106. A user interfaces the control interface via controls (not shown) on the face of the control interface 105. In some embodiments, the interface connector 104 is further coupled to the circuitry 111 of the housing unit 100, including the device-housing connector 101. In some embodiments of the present invention, the device housing connector 101 is coupled to additional circuitry 112 which allows particular electronic devices 150 to be played and controlled by the housing unit 100. In certain embodiments of the present invention, the additional circuitry 112 is programmed with media player device manufacturer-specific proprietary circuitry such as that needed to play the Apple® Accessory Protocol. Finally, the housing circuitry is coupled to the output 113. In some embodiments of the present invention, the output 113 is an audio/video output.
It is an object of the present invention that the connection between the housing unit 100 and the control interface 105 be substantially hermetic. As such, the control interface 105 possesses a number of sealing gaskets: the interface connector gasket 107, the control interface gasket 108 and the cavity interface gasket 109. The housing unit 100 has corresponding surface geometry, such as the raised nature of the interface connector 104 and the ridge 110, such that when the control interface 105 is coupled to the housing unit 100, the gasket features 107, 108 and 109 substantially hermetically seal the control interface 105 with the housing unit 100. In alternative embodiments of the present invention, the housing unit 100 contains gasket features and the control interface 105 possesses a unique geometry to substantially hermetically couple the two. Preferably, the sealing gaskets 107, 108 and 109 are comprised of a resilient material such as rubber.
In some embodiments of the present invention, the housing unit 100 is designed to accommodate a particular electronic device 150. The housing unit 100 as shown in
To connect an electronic device 150 to an audio system in a vehicle via the housing unit 100, the user first moves the controller interface 105 to an open position. The user then inserts the electronic device 150 into the housing unit 100 such that the device connector 151 couples to the corresponding device-housing connector 101 inside the housing unit 100. The user then moves the controller interface 105 to a closed position, forming a waterproof enclosure housing the electronic device 150 within. The controller interface 105 allows the user to operate the electronic device 150, now safely enclosed within the housing unit 100, and play content, such as music or other audio or video, through the vehicle's audio system. Once the electronic device 150 is coupled within the housing unit 100, the user is able to access and control the functions of the electronic device 150 through the control panel.
In alternative embodiments, the electronic device 150 is a portable digital audio player implementing MPEG-1, MPEG-2 and/or MPEG-4 technology, which enables the portable digital audio player to play videos and movies. It will be readily apparent to those having ordinary skill in the art that other video compression formats are able to be implemented in the present invention as well. In yet another alternative embodiment, the electronic device 150 is a portable digital video player and the portable digital video player is coupled to the housing unit 100.
As discussed above, the control interface 105 is coupled to the housing unit 100 in a variety of ways according to certain embodiments of the present invention.
Those skilled in the art will recognize from the context of the descriptions of the embodiments that coupled shall refer to any number of ways to couple. In alternative embodiments, the control interface 105 is coupled to the housing unit 100 via a snap connector, a hinge mount, or a tongue and groove mechanism, among other means. Those skilled in the art will recognize from the context of the descriptions of the embodiments that various means of coupling the control interface 105 to the housing unit 100 define a waterproof enclosure for the containment and protection of the electronic device 150 housed within.
As explained above, the housing unit 100 is part of a vehicle media system according to some embodiments of the present invention. When the user is ready to leave the vehicle, he will move the controller interface 105 to an open position and remove the electronic device 150 from the housing unit 100 by decoupling the device connector 151 from the corresponding device-housing connector 101 inside the housing unit 100. After removing the electronic device 150, the user will then move the controller interface to a closed position. It is another object of some embodiments of the present invention to provide a means for alerting a user that the electronic device 150 is coupled within a housing unit 100. According to these embodiments, the audio system and the housing unit 100 are coupled to the vehicle's engine such that when the engine is turned off and the key removed, a series of beeps will sound to remind the owner that the electronic device 150 is still connected and enclosed within the housing unit 100. This reminder system helps to prevent the owners from leaving the electronic device in the vehicle unintentionally.
The housing unit 500 comprises an opening 503 which receives the cartridge 575 and an interface connector 504. Furthermore, the housing unit 500 comprises a surface geometry, such as the ridge 510, such that when the control interface 505 is coupled to the housing unit 500, the gasket features (not shown) substantially hermetically seal the control interface 505 with the housing unit 500. The housing unit 500 also comprises an opening 503, a housing-cartridge connector 501 and circuitry 511, 512.
