A few of the Mallory Sonalert devices are rated within
that spec. Don't know your size, mounting or sound pressure
requirements, but e.g. the SC307N is a panel mount device
that will generate 80 dbA at two feet, on 3V with a 3mA
load. At 7V, it is rated for 90 dbA for a cost of 8mA.

No experience with it, I just happen to have one of their
brochures laying around. Check http://www.nacc-mallory.com.
