"Electroraechanical buzzer for watchers" *

The innovation concerns an electromechanical buzzer for Clocks and is particularly suitable for alarm clocks and the like.

It is known per se to add alarm clocks, but also other clocks, by means of an electric buzzer, which are in the form of a electronic magnetic relays are constructed. So these known buzzers have a coil with a coil core and a Anchor part that occurs when the coil is excited due to the Magnetic field is pulled in the direction of the coil part. The path covered by the armature is used, if necessary via a lever arrangement, to open a contact, which is arranged in the coil circuit. This causes the coil to be de-energized again, the armature drops out and the circuit will be closed again. These known buzzers are designed in an open design and without a sound membrane; how

already mentioned, they are similar to conventional relay arrangements, are ir. expensive to manufacture and require a high battery power to operate,
j

are also already purely electronically working Sumner with a sound serabran, which is known by a have a relatively modest power requirement, but the manufacturing costs are very high. In this way and V.'eise is also an economical use of this buzzer not possible.

The innovation has set itself the task of avoiding the disadvantages of the known arrangement and of creating an electronic mechanical Suisner which can be used in particular for counter clocks, which is economical to manufacture, is lightweight and compact and also has a very low battery power Auskostat.

The innovation, that of a sumr.er of the above-mentioned Art starts out, is to solve the problem in that an annular excitation coil is arranged in a pot-ready housing and above the Zrregerspule one with a vibrating armature loaded circular oscillating spring is provided and that the current ^ eg for the excitation coil via one of the Oscillating armature in rest position also contacted circular

The t-shaped housing T has a ring-shaped, horizontally running flanged edge T 7, on which a circular oscillating spring 5, which is shown in FIG. 5-is shown again in an enlarged version, with its outer parts connected to Tf ^ Jt- ^ it ^ier oscillating spring J, namely vorzttfsvreu-each through a central contact rivet 5 is a likewise circular "oscillating armature or anchor plate i + _m The oscillating spring 5 is retained on the umgebördel- th 3and the housing T lurch an attached from above retaining ring to, However, with the interposition of a spacer ring 9 of electrically insulating material. ■ in this case, the spacer ring is provided iu an internal shoulder 9 & ,, which the 3ördelrand T? of the housing for Heil attacks, so that the retaining ring To has no electrical contact with the housing at any point.
