Definitions
- the invention relates to a small one, in particular portable radio clock according to the preamble of Claim 1 or 3.
- Such a watch with an antenna is known from PAJ, vol. 6, no. 229 (P-155), November 16, 1982 to JP-A-57 132083.
- a core made of highly permeable material as Carrier provided for the antenna coil, which over an interface on the watch case ohmic with the Primary winding of a step-up transformer connected is, whose secondary winding over a variable capacity connected in parallel can be tuned is and on the also arranged in the watch case Receiver is connected.
- the antenna coil the core can be a laminate. It it is proposed to run the core either in parallel to the band of a wristwatch on one side of the to arrange the (digitally displaying) dial, or the housing and therefore its Dial area by means of a U-shaped core from three sides.
- the receiver circuit in total or at least one of their component blocks enclose in a plastic housing, which of a wide bandage made of thin-layer magnetic material that is surrounded as axial long, extremely thin hollow core one axially short thin-layer antenna coil.
- the receiver circuit board too to equip two loop antennas, their axes are oriented in parallel. At least one of them Loop antennas is with a ferrite core as a coil former equipped, and only one of the two antennas is connected to the receiver while the other, inductively coupled loop antenna is capacitively balanced.
- the one as a polarization transformer acting body of a person emits the magnetic component of a vertically polarized electromagnetic field in tangential direction and thus in an ideal orientation of the two individual antennas.
- the invention does not relate to a watch with an integrated clock Broadcast program receiver, but a small, especially portable, radio clock.
- a radio clock in of EP-B-0 180 155 described in more detail it is a autonomous clock, its current Time display from time to time based on a received Telegram about the current legal Time checked and corrected if necessary becomes.
- it is problematic in the low available Interior of the watch case also a long-wave antenna sufficient sensitivity to to accommodate the reception of the time transmitter. Even without considering this special antenna problem became a reality in the professional world a radio clock in the order of magnitude a watch is not considered realistic (see R. Bernbach and M. Lobjinski "New radio clocks from the Institute for Data Technology "in FUNKUHREN, published in 1983 by W. Hilberg, center there from page 170).
- the present invention has the object underlying a small (especially as Wristwatch configurable) radio clock in the above explained meaning with a sufficient Get the receiving antenna.
- the antenna is not after this solution more, as with the marketable wall and Table clocks, separately within the clock case next to the work capsule behind the dial attached. Rather, this solution becomes a Antenna included directly in the watch case. Particularly powerful Antennas arise when the antenna coil directly from one in accordance with the Housing design shaped core made of ferrite powder or soft magnetic particles is worn, the in its outer contour the design specifications is adjusted.
- the Watch case 14 itself as the Antenna core 16 is designed, for example made of pressed material with injected ferrite grains or Soft magnetic particles is formed.
- This housing core 16 can then in plan view 1 O-shaped or 2 as a flat pot, ie with a continuous floor 19 can be designed.
- the interior 20 takes the under Dial 18 located movement 13 on.
- a single one Coil 17 or a plurality thereof can one in the direction of the radio field component to be received 21 extending core extension 22 be wound, preferably let in into a core incision acting as a winding body 23.
- the coil 17 can also be coaxial one standing on the core floor 19 Wall 24 can be wound, as from the cross-sectional view 2 can be seen where the tubular core 16 with very much in relation to the diameter short piece of pipe on the side facing away from the dial Side of the watch case is.
