DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an intercom extension speaker attached to an intercom master unit, a sub master unit, and the like, and more particularly, to a light emitting means that flashes or lights in response to a signal from the intercom master unit or a sub master unit. The present invention relates to an intercom extension speaker having

[0002]

2. Description of the Related Art Conventionally, an additional speaker has been used by being attached to an intercom master unit or a sub master unit provided in a dwelling unit.

[0003] Here, the function of the intercom master unit or the auxiliary master unit is to notify or alert a resident of the presence of a visitor and various alarms by sound or display, and an additional speaker is also provided for the intercom master unit. Alternatively, in response to an output from the sub master unit, a notification or an alarm is similarly given by sound or display.

As such an additional speaker, for example,
There is one described in Japanese Patent Application No. 9-201411 previously disclosed by the present inventors. FIG. 13 shows a block diagram of a main part configuration of this intercom extension speaker. The intercom extension speaker detects a transfer signal output from the intercom master unit or the sub master unit, and outputs a transfer signal detection circuit 1 that outputs the transfer signal, and a signal output from the transfer signal detection circuit 1. A speaker 2 that receives the transfer signal and outputs the transfer signal as an alarm or a notification sound, and a light emission control circuit 4 that blinks or turns on a light source 5 according to the transfer signal.
And a power supply circuit 3 for driving the intercom extension speaker E
, Is provided.

[0005] The speaker terminal 8 of the intercom extension speaker is connected to the speaker terminal 6 of the intercom master or sub-master, and a transfer signal output from the interphone master or sub-master is detected by the transfer signal detection circuit 1. I do. here,
As the transfer signal, there is a ringing sound output from the intercom master unit and an alarm sound from various sensors and an alarm sound output from the intercom master unit when a call is received from the intercom slave unit.

[0006] The transfer signal input to the intercom extension speaker is short in the case of a call notification sound of a visitor, but long in the case of an alarm sound. Is changing the blinking cycle of.
