| 摘要 |
The system has a receiving antenna system (3) for digital audio broadcast (DAB) or digital multimedia broadcasting (DMB) and/or frequency modulation and/or coded reception of geolocation. Demodulators (11) are integrated in the antenna system. Data is transmitted from the antenna system to a car radio receiver terminal (12). Electromechanical speakers/transducers (10) produce sound from an electric signal. The demodulators are located after amplification-impedance matching. Adaptation-amplification-modulation or demodulation assembly is implanted within same antenna. |
