I am doing a rewire at our local hospital where I work. Inside the walls disconnected and tucked away are the speakers used with a clear plastic tube to a plastic ear piece, so the patients can listen to radio.
The speaker mounts to a wall plate and has a coupling to attach a 1/4" plastic tube to. This tube is a few metres long and connects to a plastic cup shaped earpiece that sits on the pillow. There is a 4 position switch that allows you to choose 4 radio stations.
I am after any information on these, or even what they call them. The small speakers were made by MSP, that is the only info on them.
Pillow Speakers

So that's what they look like. I guess the only people who may have first hand info on them would be former AWA employees.

AWA made heaps of nurse call systems in their day, mainly under the Sedco brand though I would imagine that MSP loudspeakers ended up being used in the white handsets fitted to these systems.

The last hospital I worked at still had an ancient Sedco system in operation and it was a bit of a bitser, combined with modern Sedco microbases feeding electronic sounders and LED screens throughout the wards and Rauland MATV system. One ward had the oddball arrangement of both a Sedco handset for nurse-call and a Rauland handset for the telly. I merged all this mish mash through some wiring changes behind the bedhead panels so everything would feed from and to the Rauland handsets as it did allow for all patient functions whereas the Sedco handsets were a good 30 years old and only allowed for piped music (no longer used) and the nurse call buzzer.

With MATV systems being converted to digital over the past decade I would imagine that there are no longer any of the older nurse call systems operating.

I have also saved the front panels that all these parts mount to. There is a stainless steel panel, around 160mm x 200mm and on this panel is mounted two power points, the speaker outlet, the volume pot and the station selector switch. Also a 75ohm coax outlet and a weird looking Bakelite four pin socket, probably the nurse call. These were done away with many years ago and we now run a Rauland's system for nurse call. All the rooms now have TV's and no radios.
If anyone wants one of these set-ups let me know, they are free to the first half dozen that contact me, you just pay the postage.
You get speaker, switch, 100 ohm pot and transformer as per the picture link above here.
My email is always open.
