ABSTRACT:
A hands-free kit for cell-phones combines the wireless capabilities of Bluetooth and the sound and visual functionalities of a tape player. A device that has a shape of a conventional magnetic cassette comprises a Bluetooth module. The module automatically detects a data communication initiated with the portable apparatus over a wireless network when the device is inserted in the tape player. Then the module automatically configures the apparatus to transmit to the device a low frequency signal representative of the communicated data. The device converts the received low frequency signal into a magnetic signal further communicated to the tape player for play out and/or display. Thus, when a cell-phone rings, a driver inserts the device in his tape player and the cell is picked up and the conversation played out loud on the loud speakers in the car.
