Definitions
- the present invention relates generally to a resonator mounted in a housing, and more particularly to the incorporation into this housing of additional electronic components.
- Such resonators are used in many fields and more particularly in the fields of watchmaking and telephony.
- the electronic watches comprise a number of additional electronic elements requiring a second integrated circuit external to that of the oscillator incorporated in the housing of the piezoelectric resonator.
- the need to have two integrated circuits and therefore two substrates or equivalent to support these integrated circuits results in a significant occupation of the space available in the watch, which requires the volume of the latter to be excessive and therefore undesirable for reasons obvious aesthetics.
- an electronic watch with display analog includes a motor for driving the analog display, for example hands, so as to display a time information provided by the time base and transmitted to the motor by means of control of the latter. Therefore, these control means of the electric motor of the watch are in the context of the present invention advantageously integrated on the same circuit as the oscillator in the housing of the resonator.
- Such a solution also has the advantage of reducing the length of the connections between the electronic elements of the watch and thus reduces the sensitivity of the oscillator to the external disturbances. This reduction of disturbances thus makes it possible to work at high impedance, more sensitive to these disturbances, and thus to reduce the general consumption of the electronic circuits of the watch while preserving an immunity to acceptable disturbances.
- Advantageous embodiments are the subject of the dependent claims.
- FIG. 1 is a schematic view of an electronic watch with an analogue display according to one embodiment of the invention
- FIG. 2 is a top view of an open housing containing the time base and the motor control circuit;
- FIG. 3 is a view along section A-A of FIG. 2;
- FIG. 4 is a schematic view of an advantageous embodiment of the present invention.
- the invention relates to an electronic watch comprising a time base formed by a resonator, for example a piezoelectric resonator, such as a quartz resonator 1, or a resonator in MEMS type silicon connected to the terminals of an oscillator 2 whose output is connected to a frequency divider circuit 3 to obtain the desired operating frequency for the watch so as to indicate the exact time.
- the output of the frequency divider circuit 3 is connected to a control circuit 4 of an electric motor 5 for driving the wheels, not shown here, rotating the analog display means, such as needles 6 for providing the indication of the time, ie hours, minutes and possibly seconds.
- a stepping motor also called bipolar
- a stator with high magnetic permeability for looping the magnetic circuit
- at least one coil having the function when it is energized, to create a magnetic field in the stator which is thus transformed into a magnet whose polarity depends on the direction of the current in the coil.
- the control circuit 4 of the motor provides a current flowing in the coil.
- the motor is controlled by a succession of positive and negative pulses spaced from power failure.
- the oscillator 2, the frequency divider circuit 3 and the control circuit 4 of the electric motor are all integrated on a single integrated circuit 7 in order to save the space occupied by the electronic elements of the watch as well as to reduce the electromagnetic disturbances on these electronic elements due in large part to the length of the wired connections between elements. Note that this reduces the number of external connections to four only instead of eight in normal times. Indeed, it is normally provided two connection terminals for the excitation of the resonator, two others for the connection with the integrated circuit, two others for the power supply of the integrated circuit and finally two for the control of the motor. Here only four terminals are needed externally on the housing, the two power terminals of the integrated circuit and the two connection terminals of the integrated circuit which also serve as control terminals of the motor.
- the two excitation terminals between the resonator and the integrated circuit are arranged only internally of the housing. Nevertheless, it will be possible to use several integrated circuits arranged next to each other without however fully benefiting from the aforementioned advantages.
- the integrated circuit 7 is powered by a power source 8 of the watch.
- the main idea here is to further reduce the space occupied by the electronic elements of the watch.
- the integrated circuit 7, possibly the integrated circuits is cleverly arranged in the same housing 9 already used for fitting the piezoelectric resonator 1 inside the watch case.
- the arrangement of the integrated circuit 7 in the housing 9 of the resonator allows no only to optimize the space occupied by all these elements inside the watch case, but also increases the protection of the integrated circuits vis-à-vis external disturbances possible through the very short connection paths between the various elements inside the housing 9 of the resonator.
- An example of arrangement of these elements inside the housing 9 of the resonator is given in connection with FIGS. 2 and 3.
- FIGS. 1, 2 and 3 are identical.
- Figure 2 is a top view of the housing 9 containing the piezoelectric resonator 1 and an integrated circuit 7 comprising the electronic elements of the watch.
- the casing is generally made of parallelepiped-shaped ceramic comprising a main part with a bottom and sides and a cover, not shown, ensuring a hermetic closure of the casing 9, for example by vacuum welding or any other suitable means for obtaining a hermetic assembly.
- the cover is provided in glass so as to make it possible once to make the case hermetically closed a precise laser adjustment of the frequency of the resonator, which has the advantage of avoiding the difficult functions to be implemented.
- the piezoelectric resonator 1 and the integrated circuit 7 are mounted in the main part of the housing.
- the resonator is preferably a tuning-fork quartz resonator whose base 11 and vibrating arms comprise metallizations which form two groups of electrodes 12 and 13 which make it possible to subject them to electric fields in order to make them vibrate.
- the connections between the resonator 1 and the integrated circuit 7, are preferably made by means of holes 22 formed in the rungs 17 and filled with a conductive adhesive, or any other suitable conductive material, providing the connection with conductive tracks.
- connection terminals 14 and 15 connected on the one hand with the outside of the housing and on the other hand, with the inside of the housing. Inside the housing these four connection terminals are connected to the integrated circuit 7. Outside the housing, the two connection terminals 14 are connected to the power supply, shown in FIG. supplying the integrated circuit 7, and the other two connection terminals 15 are connected across the coil of the electric motor to provide positive and negative electrical pulses.
- the proposed connections are only as a non-limitative example, and that of the same as an alternative, it suffices that two terminals among the four terminals 14 and 15 are connected to the power source on the one hand, and that the other two remaining terminals are connected to the motor coil of other go.
- FIG. 3 is a view in median and longitudinal section along section AA of FIG. 2. As can be seen in this FIG. 3, the resonator 1 is mounted by welding or bonding with a conductive glue the connection pads of FIGS.
- connection between the connection pads located on the base of the resonator 1 and the integrated circuit 7 for effecting the excitation of the electrodes and ensuring the vibration of the resonator can be done as already mentioned in relation with FIG. through the conductive pads 16 connected to holes 22 formed in the rungs 17 and filled with a suitable conductive material, connected to the conductive tracks 23 (see Figure 2) themselves connected to the integrated circuit 7.
- connection pads 18 are advantageously located under the integrated circuit 7 connected to the terminals.
- connection 14 and 15 via tracks or conductive pads 19 (see Figure 2) and holes 20 through the bottom of the housing 9 and filled with a conductive adhesive 21 or any other suitable conductive material. These holes being located opposite the connection terminals 14 and 15, the conductive adhesive provides the electrical connection with the inside of the housing.
- Figure 4 shows a particularly advantageous embodiment according to the present invention.
- connection between the connection terminals MOT1 and MOT2 of the housing 9 is provided, corresponding to the output terminals of the motor control circuit, and the motor coil to allow the transmission of positive and negative electrical pulses via either one of the connection terminals, which ensures the proper the hands and therefore the time indication for the watch.
- connection terminals for example MOT1 enabling the positive pulse transmission
- a switch actuated by an external control member of the watch Actuation of this switch blocks motor control and thus interrupts the time indication. This interruption is necessary to allow the delivery on time of the watch.
- the external control member used is the crown rod.
- the user has only to pull the crown rod from the depressed position 1 to the pulled position 2 to interrupt the time indicating mechanism, the switch passing from its position open (position 1) to its closed position (position 2).
- One of the advantages is that when the crown is pulled out, the switch is then conductive and the motor pitches are stopped which makes it possible to share the connection terminal MOT1 without difficulty and to further reduce the connections.
- motor control on the one hand, and engine stop on the other hand exclude time.
- control member may be a push button or other two-position mechanism easily actuated by the user of the watch.
