Recently the door phone for entrance is being the mainstream with camera like a mobile phone, though there is also a time when a chime was called as ping-pong before.
But in M's project of Nishio city, I will install a door bell which has been never seen now in Japan.
The sound is "RIRIRHHHHHIIIIIN", like at a platform in the old train station.
I had a request from the customer whether there isn't something of such feeling and searched and found it in Canada as a picture.
Small body made of steel which did silver plating. Dry cells was connected and rung on probation, but it's quite noisy then.
How do you think about such a retrospective item?
It seems to be my customer who eagers to put something fascinating.
