Embodiment 1

[0054] An electronic thermometer according to Example 1 of the present invention will be described with reference to FIGS. 1 to 9 . FIG. 1 is a plan view of an electronic thermometer according to Embodiment 1 of the present invention. Fig. 2 is a block diagram of an electronic thermometer according to Embodiment 1 of the present invention. 3 is a partially cutaway perspective view of the electronic thermometer according to Embodiment 1 of the present invention. Fig. 4 is a perspective view showing a state in which various components are assembled in the inner case according to the first embodiment of the present invention. 5 is a perspective view showing a state in which a buzzer and a buzzer cover (pressing member) are assembled in an inner case according to Embodiment 1 of the present invention. Fig. 6 is a six-sided view of the buzzer cover in Embodiment 1 of the present invention. Fig. 7 is a diagram showing a fixing structure of a buzzer according to Embodiment 1 of th...

Embodiment 2

[0078] Fig. 10 shows Embodiment 2 of the present invention. In this embodiment, a modified example of the buzzer cover as the pressing member is shown. Since other structures and functions are the same as those in Embodiment 1, the same symbols are assigned to the same structural parts, and their descriptions are omitted. Fig. 10 is a schematic diagram of a buzzer cover according to Embodiment 2 of the present invention. In addition, FIG. 10( a ) is its top view, and FIG. 10( b ) is its cross-sectional view (AA cross-sectional view in FIG. 10( a )).

[0079] The buzzer cover 70a of the present embodiment is also made of a material such as resin and has flexibility, as in the first embodiment. Moreover, this buzzer cover 70a has: a disc-shaped body portion 71a, a protruding portion 72a provided in the center of the body portion 71a, a substantially cylindrical pressing portion 73a provided along the edge of the body portion 71a, and a pressing portion 73a for pressing. A pai...

Embodiment 3

[0085] Fig. 11 shows Embodiment 3 of the present invention. In the cases shown in the first and second embodiments, the buzzer cover as the pressing member is provided with a protruding portion, and the buzzer cover bends when the protruding portion abuts against the inner wall surface of the outer case. In the case shown in this embodiment, a protruding portion is provided on the inner wall surface of the outer casing, and the buzzer cover is bent by the protruding portion. The other structures and functions are the same as those in Embodiment 1, so the same symbols are assigned to the same structural parts, and their descriptions are omitted. 11 is a part of a cross-sectional view in the longitudinal direction of an electronic thermometer according to Example 3 of the present invention. Furthermore, FIG. 11 shows a cross section at the same position as in FIG. 9 in the first embodiment.

[0086] The buzzer cover 70b of this embodiment differs only in that the buzzer cover ...

Abstract

The electronic thermometer of this invention includes a supporting portion which supports the vicinity of the periphery on one face of a vibration plate, and a buzzer cover having plasticity of pressing the vibration plate against the supporting portion by pressing the vicinity of the periphery of the other face of the vibration plate and further includes a mechanism which presses the vicinity of the center of the buzzer cover on an opposite side to a side provided with the vibration plate in the buzzer cover so as to flex the buzzer cover, thereby pressing the vicinity of the periphery on the other face of the vibration plate with elastic reaction force of the buzzer cover.

Description

technical field [0001] The invention relates to an electronic thermometer. Background technique [0002] Conventionally, there is known an electronic thermometer provided with a buzzer in order to let the user know when the measurement of the body temperature is completed or the like. In such an electronic thermometer, how to make the small buzzer generate a large volume has become a technical issue. [0003] As a method for making a small buzzer generate a loud volume, there are known techniques of forming a resonance space that resonates with the vibration sound of a vibrating plate included in the buzzer, or forming a resonance space in a case that supports the buzzer. A resonant part resonating with the vibration of the vibrating plate is provided in the center (refer to Patent Document 1). In order to effectively exhibit such resonance action and resonance action, it is essential to vibrate the vibrating plate included in the buzzer as set. Furthermore, in order to v...
