ABSTRACT:
A device primarily for attachment to the spout of a teakettle for generating a musical signal in response to the vapor pressure of boiling water. A diaphragm distorts in response to the pressure and closes an electrical switch which applies battery voltage to a circuit in which a representation of a pre-selected tune is stored. The tune is applied to a piezoelectric speaker within a resonating housing to audibly signal the user that the water in the teakettle is boiling.
