Abstract
Abstract An envelope of an electronic clinical thermometer has an inner wall on which is mounted a vibrating element adapted to produce an audible tone. The portion of the envelope at which the vibrating element is provided is formed to include a portion that vibrates together with the vibrating element, when the latter is set into operation. The mounting arrangement for the vibrating element is defined in part by a recess formed in the inner wall of the envelope.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
168 words
An electronic clinical thermometer, comprising: an integrally formed one piece envelope having a wall defining a hollow interior for accommodating circuit components for sensing, measuring and displaying temperature, said one piece envelope being sealed liquid-tightly; resonance means integrally formed in a portion of said wall defining said hollow interior of said envelope, said resonance means being defined by a wall section of said envelope wall which is thinner than the remainder of said envelope wall, thus forming a cavity in said envelope wall, which cavity opens to said hollow interior; and vibrating means which is energizable for producing an audible tone, said vibrating means being secured onto said wall section of said resonance means; said resonance means and said cavity formed thereby being dimensioned such that boundary portions of said wall section at its intersection with the remainder of said envelope wall define nodes of vibration, said, resonance means vibrating in resonance with said vibrating means when said vibrating means is energized to thereby produce said audible tone.
Claim 2
Dependent Claim
168 words
An electronic clinical thermometer, comprising: an integrally formed one piece envelope having a wall defining a hollow interior for accommodating circuit components for sensing, measuring and displaying temperature, said one piece envelope being sealed liquid-tightly; resonance means integrally formed in a portion of said wall defining said hollow interior of said envelope, said resonance means being defined by a wall section of said envelope wall which is thinner than the remainder of said envelope wall, thus forming a cavity in said envelope wall, which cavity opens to said hollow interior; and vibrating means which is energizable for producing an audible tone, said vibrating means being secured onto said wall section of said resonance means; said resonance means and said cavity formed thereby being dimensioned such that boundary portions of said wall section at its intersection with the remainder of said envelope wall define nodes of vibration, said, resonance means vibrating in resonance with said vibrating means when said vibrating means is energized to thereby produce said audible tone.
Claim 3
Dependent Claim
17 words
The electronic clinical thermometer according to claim 1, wherein said vibrating means comprises a piezoelectric vibrating element.
Claim 4
Dependent Claim
17 words
The electronic clinical thermometer according to claim 1, wherein said vibrating means is mounted in said cavity.
Claim 5
Dependent Claim
25 words
The electronic clinical thermometer according to claim 3, wherein only peripheral portions of said vibrating means are secured onto said boundary portions of said cavity.
