The literature that came with the K1EL keyer IC suggests Radio Shack
part number 273-073 "Piezo Transducer" - 1500-3000 Hz. The volume is
somewhat low but usable in a quiet location. This part is approximately
2 cm. in diameter and 0.75 cm. thickness with two wire leads. Another
source might be the sounder unit from a burglar alarm keypad assuming it
works as a transducer rather than producing a tone by applying a d.c.
voltage.
Good luck.
