A building-block system framework comprises a host device and a plurality of independently operable function devices, in which each device is provided with a conversion circuit (a codec and interface circuit, etc.) for converting signals into common standards (USB or IEEE1394, etc.), such that the signals can be transmitted to the host device and those function devices. The function devices could be a musical accompaniment, TV set, phonographic equipment (including an FM/AM receiver or amplifier), CD player, phone set, etc. The host device is supposed to run an indispensable operating software for controlling the function devices, by which a user could selectively operate the function devices according to the detection results showing whether a function device is existed or not. Since each function device is provided with a conversion circuit, signals can be transmitted in standard specifications, and no matter whichever a function device is added or deleted, the whole system can operate smoothly without being affected. Moreover, all the function devices can operate independently irrespective the operating state of the host device, no matter opened or closed.
