Abstract: An in-vehicle multimedia device includes: an antenna module which has an antenna body arranged on the outer side surface of the roof of a vehicle, a first circuit substrate coupled to the antenna body, a connector part provided with through-holes therein formed to project downward from the lower surface of the antenna body, and first connection pins accommodated in the respective through-holes of the connector part and electrically connected with the first circuit substrate, a tuner part module which has a tuner part body arranged on the inner side surface of the roof of the vehicle, a second circuit substrate coupled to the tuner part body, and second connection pins provided in a coupling groove such that the connector part is inserted and coupled; and a coupling member that couples the antenna module and the tuner part module to each other.
Abstract: A car audio system having a tuner unit and an active antenna integrated into a single module, the car audio system being connected to an antenna for a vehicle and receiving broadcast signals, is provided. The car audio system includes an antenna-tuner integration module, in which the active antenna for receiving and amplifying the broadcast signals and the tuner unit for selecting a broadcast signal corresponding to a specific frequency among the received broadcast signals are formed as a single module; and a car audio device connected to the antenna-tuner integration module using a data cable of a certain length corresponding to a spaced distance for preventing effects of electrical noise generated by the vehicle.
