Looking for a sound generator chip

T

Tim

Hi,
I'm looking for an IC to generate a simple pleasant tone to use in a medical
product.

The tone will be for a patient call button. A simple chime or pleasant gong
will do.

I cannot find anything like this out there.

Can anybody point me to a manufacturer of such chips?

Thanks,
Tim

What triggers it? what does it hook up to? Single switch closure for room
only?

Hi, Tim:-

Your easiest solution is probably the Siemens (Infineon) SAE 800.

If that doesn't meet your needs, you could consider rolling your own
with a micro+amplifier.

Siemens (now infineon) SAE800
In stock at digi-key
Does 1,2 or 3-tone 'bongs'
Sound is a little on the crunchy side - the steps in the decay are slightly noticeable.

You may be able to do better with a little microcontroller, PWMing the waveform and envelope from a
lookup table.

maybe a solid state square wave oscillator with a remote trigger, each
remote could have an led as well. no need to use a sledge hammer when a
fart will do.

Just have the patients call the nurse's cell phone. ;-)

Hey Rich,

What about using a voice recorder chip. Radio Shack sells them. You can
record any fancy sound you like. Can't tell you about audio quality
however.

Good luck.

ISD, now owned by the Taiwan-based company Winbond. Pretty crappy
sound quality, IMHO. They use EEPROM cells to store analog voltages.

Winbond also have polyphonic ringtone ICs that will do MIDI synthesis
as well as ADPCM.

Hey, why not hire a talented musician/composer to come up with a
custom MIDI gong composition that will wind up and drop-kick the
patients through the goal posts of good health?

I abused a greeting card once for that porpuse (the once with a

Hello Ryan,
I abused a greeting card once for that porpuse (the once with a
built-in tone generator)

We have a bottle opener that mumbles "Have a beer ... glug, glug,
glug...". But I doubt its chip would qualify in a medical product ;-)

I have a PIR-actuated battery-powered annunciator that I bought from
some place because it was just too cheap to pass buy. It records a few
seconds of fairly high quality sound for the message, and the message
plays whenever the PIR sensor sees someone passing nearby. I got an
amusing sound bite to greet visitors with a brief visit to the
bathroom.... it was pretty funny for a few days anyway.


Best regards,

Dear Tim,

We do have standard sound chip for your production. Can you pleased tell us
your operation voltage and QTY request ?

We do can send you simple for engineering approval !

Thanks !

Drum set functions too. Maybe he could get it to play some appropriate
Chopin if the EKG signal so indicates. ;-)

Or "Taps" if there is no EKG signal? ;-)

I had about 100 of those annoying musical greeting cards with dead
batteries. I thought about putting a 1N34 diode, cap and short wire
antenna on them, then leaving them scattered all over a AM radio station
to annoy the staff, but on second thought I decided that by the next day
they would either level the building, or rip out everything and throw it
in the parking lot till they found all of them.

A few years back, the company gave out alarm clocks (cheap ones, of
course) to all the employees for some reason or the other. One
enterprising employee 'borrowed' a few of them, and, after setting to
different times, hid them around the bosses office. I cabinents, taped
under tables, above the ceiling tiles, in the ventilation duct...

Was entertaining as he tore his office apart looking for all of them!

Back in the early '80s I worked for a large CATV systems operator. I
took care of the head end and repaired all their electronics while
trying to stay ahead of destructive customers and subcontractors who
constantly dropped equipment. The regular feild staff kept bragging
that they were going to pull an outragous stunt on the boss when he got
back from vaction, but as usual their plan was quite lame. I told them
they couldn't even plan a real stunt, let alone pull one off. They told
me I couldn't come up with anything better so i smiled and told them to
go to the lubmer yard to pick up two sheets of drywall and a 10 foot
piiece of baseboard that matched the existing baseboard, a gallon of
readymix drywall compound and paint to match the walls so they could
cover both doors to his office. Then we would get everyone to pretend
they had no idea who he was when he got back. You should have seen the
looks on their faces! ;-)

My next suggestion was to move all his office furniture and new color
TV into our warehose and bring a bunch of the empty and nearly empty
wood spools to replace the furniture, and put a decripet old 12 inch B&W
TV in his office. It turned out that they were all talk and no action.

I was a Broadcast engineer in the early '70s at a military TV station
in Alaska. The on air "Talent" had to wear their dress uniforms for the
newscasts, but they would sit behind the news desk in their boxers
because of the heat from the lights. When I had to run an "Actuality"
(A report recorded off the AFRN network and used with 35 mm slides) they
would jump up and shadow box or goof around. Quite often they were late
getting back in their seats so it looked like I couldn't switch cameras
on cue. After a week of their crap I rewired the studio monitors so
they didn't follow the on air signal. That night I got half way through
their first long "Actuality" and switched the video and audio monitors
to the preview circuits. They froze and looked at the dead speakers
first, and then at themselves on a coule video monitors that showed them
on air and out of uniform. They freaked out and ran behind the news desk
as I switched the monitors back to the on air signal. As soon as the
news was over they were in the control room screaming at me and calling
the station amanger about what they thought I had done to them. He had
no idea what they were talking about and assured them that he had
watched the entire newscast, and no, they were not seen in their boxers.
I was grinning when they turned back to me and told them that they had
recieved their one and only warning to stay seated during the newscast.
I wonder why people always told me that I wasn't very "GI"?

BTW, they reminded me of Les Nesman of WKRP, and Ted Baxter on the
Mary Tyler Moore shows.
