Title: Electronic clinical thermometer

Abstract: An electronic thermometer contains inside its main body not only a temperature detecting device and a display device for displaying the measured body temperature but also a buzzer for outputting a warning sound. The buzzer is formed with a piezoelectric plate on an oscillating plate, having an elongated shape and being securely supported only at mutually opposite end parts in its longitudinal direction, and these end parts remain fixed in the primary mode of oscillation. A resonance chamber is formed between the buzzer and its support structure. A buzzer cover, which serves to secure the buzzer by contacting it only at its end parts, also contacts the main body in a direction opposite from the support structure so as to propagate the buzzer oscillations to the main body.
