2. Discussion of Related Art
Media devices for a vehicle, such as an overhead display and a headrest display, are popular because passengers can enjoy audio and video entertainment on the road. Conventionally, a switch assembly including, for example, a panel having control buttons and a circuit board having circuitry for controlling the media device is not interchangeable from the console of the media device. A switch assembly may have a design or look in connection with a particular brand. In the market, one brand of a media device may be more popular than another even though both brands may function essentially the same. When the demand for the popular brand increases, and the demand for the unpopular brand decreases, the unpopular brand may be overstocked.
Therefore, there is a need for an interchangeable switch assembly for vehicle media devices to replace the switch assembly of the unpopular brand with the switch assembly of the more popular brand.
According to an embodiment of the present invention, a media device for a vehicle includes an interchangeable switch assembly, and a console including a receiving part accommodating the interchangeable switch assembly.
The interchangeable switch assembly may include a switch panel and a circuit board.
The interchangeable switch assembly may further include a backlight unit for providing light to the switch panel.
The console may further include an opening for receiving a data source.
The opening may further include a light pipe formed around the opening.
A light source of the light pipe may be changeable between at least two colors.
The console may include a switch for selecting a color of the light source.
The backlight unit and the light pipe may display a same color.
The light pipe may comprise a transparent plastic material.
The switch panel may include a plurality of buttons.
The circuit board may include at least a mating pin connector.
The interchangeable assembly can be mounted to the console by screws.
According to an embodiment of the present invention, a media device for a vehicle includes an interchangeable switch assembly, a console including a receiving part accommodating the interchangeable switch assembly, a media player disposed in the housing, wherein the media player receives a data source through an opening in the console, and a display attached to the console for displaying image using the data.
According to an embodiment of the present invention, a method for changing a switch assembly in a media device for a vehicle includes removing a first switch assembly having a backlight unit of a first color from a console of the media device, disposing a second switch assembly having a backlight unit of a second color to the console of the media device, and selecting the second color as an illuminating color of a light pipe formed around an opening in the console.
