DE3815514A1 - Small timepiece - Google Patents

Abstract

Small timepieces having liquid-crystal displays are known. According to the invention, such a small timepiece is improved by accommodating in the housing a miniaturised radio receiver for receiving frequency- or amplitude-modulated signals, the output signals of which receiver can be fed to a headphone (ear piece). <IMAGE>

Description

The invention relates to the improvement of an electrical operated small clock with hands or liquid crystal Display.

"Small clocks" are generally used to refer to clocks which are to be worn on the body, here in particular arm watches, but also by means of a chain or a ban of pocket watches to attach to clothing as well stopwatches with a cord to hang around.

Wristwatches also have designs that in addition to the pure time display are also able to display more functions, especially as  Stopwatch can serve. The case of these watches is in general compared to pure time display clocks larger, especially the ones necessary to operate the watch To be able to attach control buttons on the edge.

Stopwatches are usually similar to a pocket watch housing. This form of housing has been chosen for the Ge tried and tested, as this makes the different ones on the outside Edge of the stopwatch arranged knobs, easy to be serve and the display of the stopwatch is also easy is to be read.

The improvement of such small clocks will be according to the inven seen in that within the case of the watch a radio receiver is housed, whose signals are over headphones can be heard. The radio receiver should both frequency modulated (FM signals) as also receive amplitude modulated (AM signals) signals or can process, both with mono and also with stereo sound. To choose the desired station serve as a small turntable integrated on the housing. In addition, an on / off switch should be provided on the housing be, like possibly another switch for small or large volume or another rotary knob for continuous adjustment of the desired one Volume.

In the drawing, the invention is shown schematically on a improved stopwatch shown, showing:

Fig. 1 is a front view of a stop watch,

Fig. 2 is a side view and

Fig. 3 is a bottom view;

Fig. 4 shows a circuit for receiving frequency modulated signals;

Fig. 5 and

Fig. 6 show printed circuits for using stopwatch chips.

A liquid crystal display ( 2 ) is provided in the housing ( 1 ) of a stopwatch, on which not only the stopped time, but also the normal time in 12 or 24 hour division, as well as the date, possibly with day of the week and month, can be read. In addition, an alarm function can be provided so that an alarm signal sounds after a certain time. As is known, the stopwatch is operated by adjusting buttons ( 3 , 4 , 5 ), an adjusting button ( 4 ) being pressed at the beginning of the stopping time, an adjusting button ( 5 ) at the end of the stopping time and an adjusting button ( 3 ) for resetting the stopping time becomes. Of course, the arrangement of several control buttons is also possible.

Integrated in or on the housing ( 1 ) of the stopwatch is a turntable ( 6 ) which is used to set the desired sensor. In a on the underside of the housing arranged mounting block ( 10 ) for a cord ( 9 ) is a combined switch ( 7 ) is housed, which serves both as an on / off switch, as well as volume switch, for setting the desired low or increase the volume. Also provided on the underside of the stopwatch housing ( 1 ) is a socket ( 8 ) for inserting a corresponding headphone plug.

The circuit shown in Fig. 4 is housed in a chip that fits into the housing ( 1 ) of the stopwatch, as well as one of the chips shown in Figs. 5 and 6, which serve the stopwatch function. Furthermore, in the housing ( 1 ) of the stopwatch, a recording space is also provided for a battery necessary for operating the stopwatch and the radio receiver.

By the stopwatch according to the invention is the union a sophisticated stopwatch given along with an equally sophisticated radio receiver.
