Abstract
Abstract An improved electronic alarm watch is disclosed having improvements in the structure and arrangement of the accoustically alarming vibrator employed in the alarm mechanism thereof. The improved watch of the above type comprises a watch casing, wherein is located a watch movement, alarm switch controlled thereby, alarm oscillator circuit and a battery source adapted for energization thereof. An oscillatory membrane is fixedly attached with a piezo-electric or electro-strictive element which is electrically connected through the switch with the oscillator circuit and the battery for being energized therefrom, the membrane being arranged in a space defined by and between a perforated back cover and the watch movement.

In a watch with an electronically driven alarm, the watch comprising in combination, a watch casing with a watch movement contained therein, an alarm switch controlled thereby, an electronic alarm oscillator circuit contained within said casing and a source battery adapted for energization of said oscillator circuit and contained within said casing, the alarm comprising an oscillatory membrane and a piezo-electric or electro-strictive element fixedly attached to said membrane and electrically connected through said switch with said oscillator circuit and said battery for being energized therefrom, said membrane being arranged in a space defined by and between a perforated back cover and the watch movement and tightly supported at its peripheral area on a membrane carrier which is arranged between said back cover and said watch movement.
Claim 2
Dependent Claim
127 words
In a watch with an electronically driven alarm, the watch comprising in combination, a watch casing with a watch movement contained therein, an alarm switch controlled thereby, an electronic alarm oscillator circuit contained within said casing and a source battery adapted for energization of said oscillator circuit and contained within said casing, the alarm comprising an oscillatory membrane and a piezo-electric or electro-strictive element fixedly attached to said membrane and electrically connected through said switch with said oscillator circuit and said battery for being energized therefrom, said membrane being arranged in a space defined by and between a perforated back cover and the watch movement and tightly supported at its peripheral area on a membrane carrier which is arranged between said back cover and said watch movement.
Claim 3
Dependent Claim
44 words
Alarm watch as set forth in claim 1 wherein said membrane, together with said piezo-electric or electro-strictive element and a membrane carrier, is electrically so connected with the alarm oscillator circuit as to be easily detachable therefrom, and thus equally from the watch unit.
Claim 4
Dependent Claim
18 words
Alarm watch as set forth in claim 1, wherein said membrane is made of a conductive metal foil.
Claim 5
Dependent Claim
23 words
