Abstract
Abstract A buzzer for a watch has an electromagnet system attached to a support arm, one end of which can be fixed in the watch and the other, free end of which can be adjusted relative to a membrane with a first adjusting element which is in a contacting relationship with the watch. The buzzer has a tongue, clamped tightly on one side, which can be excited to oscillate by the electromagnet system and which strikes against the membrane either directly or indirectly. The location of the tongue relative to the electromagnet system is adjustable by means of a second adjusting element acting on it in the vicinity of the tightly clamped end of the tongue.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
135 words
In an electromagnetic buzzer for a watch, said buzzer of the type having a membrane with associated projecting pin means, an electromagnet system, a support arm carrying the electromagnet system, one end of which support arm is fixed to the watch and the other movable end of which can be adjusted relative to said pin means, and a tongue clamped on one end and arranged to be excited to oscillate by the electromagnet system and strike said pin means, the improvement comprising: first adjusting means on said movable end of the support arm opposite the electromagnet system for positioning said support arm relative to said pin means, second adjusting means acting near the clamped end of the tongue for positioning the tongue relative to the electromagnet system, said second adjusting means acting through reducation means.
Claim 2
Dependent Claim
135 words
In an electromagnetic buzzer for a watch, said buzzer of the type having a membrane with associated projecting pin means, an electromagnet system, a support arm carrying the electromagnet system, one end of which support arm is fixed to the watch and the other movable end of which can be adjusted relative to said pin means, and a tongue clamped on one end and arranged to be excited to oscillate by the electromagnet system and strike said pin means, the improvement comprising: first adjusting means on said movable end of the support arm opposite the electromagnet system for positioning said support arm relative to said pin means, second adjusting means acting near the clamped end of the tongue for positioning the tongue relative to the electromagnet system, said second adjusting means acting through reducation means.
Claim 3
Dependent Claim
25 words
The buzzer set forth in claim 1, wherein one pole of an electromagnet of said electromagnet system facing the tongue is covered with plastic film.
Claim 4
Dependent Claim
55 words
The buzzer set forth in claim 1, wherein an elastic element, especially in the form of an elastic block or a spring washer, is arranged between the movable end of the support arm and the watch, and in that the first adjusting element is a screw extending through the support arm and said elastic element.
Claim 5
Dependent Claim
67 words
The buzzer set forth in claim 1, wherein said reduction means comprises a lever, one end of which is fixed relative to the supporting arm in the area of the fixed end of the tongue and arranged so that the second adjusting means is in a contacting relationship with its other end and is in an operative connection with the tongue between the ends of the tongue.
Claim 6
Dependent Claim
123 words
The buzzer set forth in claim 4 further having a fixedly clamped block arranged between support arm and tongue on the opposite side of the electromagnet system from the movable end of the support arm, characterized in that the lever is located on the side of the support arm facing away from the electromagnet system, in that the second adjusting element is in a contacting relationship with the support arm between the first adjusting element and the electromagnet system, and including a pin slidably located in said block which extends at roughly right angles to said tongue and extends through the support arm, with one end of the pin in a contacting relationship with the lever and the other end with the tongue.
Claim 7
Dependent Claim
15 words
The buzzer set forth in claim 5, wherein the ends of said pin are spherical.
Claim 8
Dependent Claim
25 words
The buzzer set forth in claim 5, characterized in that said block is attached to the watch and supports the support arm and the tongue.
Claim 9
Dependent Claim
61 words
The buzzer set forth in claim 4, having a firmly clamped block arranged between support arm and tongue on the side of the electromagnet system facing away from the movable end of the support arm, wherein said lever is arranged between said tongue and said block and in that said second adjusting element is in a contacting relationship with said block.
Claim 10
Dependent Claim
30 words
The buzzer set forth in claim 8, wherein the fixed end of the support arm is attached to the watch and that the block is attached to the support arm.
Claim 11
Dependent Claim
21 words
The buzzer set forth in claim 8, wherein said lever is in a contacting relationship with the tongue along a line.
Claim 12
Dependent Claim
16 words
The buzzer set forth in claim 8, wherein said block defines a slot forming the lever.
Claim 13
Dependent Claim
19 words
The buzzer set forth in claim 8, wherein the lever is a section firmly clamped between block and tongue.
Claim 14
Dependent Claim
38 words
The buzzer set forth in claim 8, wherein the lever is a flat strip of sheet metal which is clamped between block and tongue together with a shorter strip of sheet metal located between it and the tongue.
Claim 15
Dependent Claim
39 words
The buzzer set forth in claim 8, wherein said second adjusting element is a screw for which said block has a thread, and in that the screw is accessible through a hole in the support arm or engages therethrough.
Claim 16
Dependent Claim
