<p>PURPOSE:To miniaturize a terminal device by providing an analog switch within the main body of a speech synthesizing outputting device to control the ON/OFF of connection between the main body and a terminal speaker and terefore outputting the sounds through a desired speaker. CONSTITUTION:A speaker switching part 23 consists of latches c(O)-c(m) for main speaker, analog switches d(O)-d(m), etc. and is connected to a CPU41 via a bus line. The latch corresponding to the signal is set at the part 23 by a signal for selection of terminal device sent from the CPU41 among those latches c(O)- c(m). Therefore the corresponding one of those switches d(O)-d(m) is turned on. Under such an ON state, the conduction is secured among a filter, an amplifier part 22 and a deisred speaker to deliver the sounds. This eliminates the need to provide a speech synthesizing/outputting circuit to a terminal device. Thus the terminal device is miniaturized.</p> |
