Need a beeping device

[Richard]

Hi,
I am looking for a component to control from a microcontroller to make
a beeping noise, nothing to loud but to sound electronic and not like a
buzzer. I just need an audible alert that is not to irritating. Any ideas
would be great, I don't have a DAC on the microcontroller, and the
simpler the better.

Thanks

Go to the DigiKey website, type 'audio'
into the search box, and you'll get
a couple thousand beepers, buzzers,
sirens and speakers to choose from.

Go to a Radio Shack store if there are any in your area, they have beepers.

Define 'simple'. If your microcontroller has spare PWM or frequency
outputs,
a capacitor and a speaker (or even an earbud from a broken headset)
will do the job. Is size important (wristwatch-style piezoelectric
transducers are small), or parts count (there are sonic-output
functional modules), or mounting in a panel (things like Mallory
Sonalert come with mount hardware kits)?

In terms of simplicity of wiring, you could use a relay to control
your
doorbell (which might be a full four-second Westminster chime with
motorized sequencing), it'd STILL be 'simple' in some sense.
