Abstract

PURPOSE:To suppress the damage due to earthquake to min. limit through automatically giving an alarm before the inversion of the main quake, by securing the automatic broadcast of the contents of output synthesized an reproduced by a voice synthesizing device when the initial microquakes are detected by a sensor. CONSTITUTION:When a sensor 6 detects the initial microquakes, the sensor 6 delivers a sense signal 7 to an amplifier 1 and a voice synthesizing device 5. Thus the amplifier 1 automatically applies the power source and gives the output according to the indicated value of volume which is previosly set to speakers SP1-SPn. On the other hand, the device 5 is automatically set under the reproduction mode with reception of the signal 7 and synthesizes and reproduces the contents recorded to a semiconductor memory to give the reproduced output to the amplifier 1. In such way, the information on the refuge and guidance is automatically broadcasted.
