<p>An adapter (301) is receivable within a cassette player (304) mounted within a vehicle. The cassette player is configured to transmit audio signals to loudspeakers mounted within the vehicle. The adapter includes an amplifier, a first detection arrangement and a second detection arrangement. The first detection arrangement is configured to detect that the adapter has been placed within a cassette player and to thereby energise the second detecting arrangement. The second detecting arrangement is configured to interact with a cassette drive mechanism so as to present a mechanical interaction similar to that presented by an actual cassette and to energise the amplifier. In this way, power consumption is reduced substantially and the adapter is not rejected by sophisticated cassette mechanisms.</p> |
