Call it the Heart of a Doll, because that’s what it was, once upon a toy store. Today it’s a red, heart-shaped plastic thingy, 2-1/2" wide x 7/8" thick, with a smaller heart-shaped button on top. And yeah, it’s a little creepy. Hold the button and it emits a soothing electronic heartbeat at a tad under 60bpm. Runs on (2) button cell batteries, included.

Our little solid-state buzzer is a diminutive 9/16" x 3/32" x 1-1/4" but it buzzes along at 8,000 hertz. Rated for 6VDC 20mA, but works fine with as little as 3V. Mounting brackets with holes on the back of the short sides, 4" wire leads. Lotta buzz for the buck.

It will if you buy this unused take-out sound device and speaker. Includes a printed circuit board and a 2” 1/4W speaker mounted inside a 2-1/4” square x 1-1/16” gray plastic box. Includes a (3) “AA” battery box (empty) and power switch on one pair of leads, and a photocell in a brass tube on another because it’s motion sensitive. The sound is officially a dinosaur growl, although some folks here maintain it is quite distinctly a dino belch. A dyspeptic dinosaur is an angry dinosaur, we always say, so it’s a fine line.
