Title: Amplifying device
Inventor: NISHIHAMA YASUO
IPC: H04R27/00
Filed: 1981-10-29
Abstract: PURPOSE:To ensure an official announcement suited to the environmental conditions of  the place of installation of a loudspeaker amplifying device, etc. and to the life time  of the residents, by providing a controller to said amplifying device to change the  amplification factor of an amplifying circuit in response to a time signal which is delivered from a timepiece device at a prescribed time point. CONSTITUTION:For a loudspeaker amplifying device, etc., the sound signals supplied from a transmitting source 1 are sent to an amplifier 12 which is set along the flowing route of a river for example. The amplifier 12 amplifies the sound signals through an amplifying circuit 3 and transmits these signals to eastern and western loudspeakers 4 and 5 via controller 10 and 11 respectively. Thus an official announcement is transmitted to the correspondent residents. A timepiece device 9 transmits the time signal  which shows a prescribed time point to the controllers 10 and 11 at the set time. When  the time signals are received, the controllers 10 and 11 change the amplification factor  or the circuit 3 to increase or decrease the sound volume of the speakers 4 and 5  respectively. Thus the official announcement is transmitted to the residents with a level of sound volume which is suited to the environmental conditions of the corresponding  territory. This does not promote the noise pollution.
