Definitions

  • the invention relates to an alarm device, in particular in an alarm clock or appointment clock, the alarm signal of which can be interrupted by an acoustic signal formed by the human voice either only for a period of time or can finally be switched off.
  • an acoustic signal formed by the human voice either only for a period of time or can finally be switched off.
  • Both the interruption of the alarm signal - in the case of alarm clocks, this process is controlled by a so-called wake-up device (English: snooze) - and the switching off of the same, takes place in the alarm device according to the invention independently of the information contained in the acoustic signal, for example a word or one Word order of a language.
  • Such an alarm device is known from US Pat. No. 3,855,574. It describes an alarm clock with a wake-up device in which the alarm signal emitted by the alarm device at intervals can be interrupted by an acoustic signal formed by the human voice for a definable period of time (snooze time).
  • the acoustic signal formed by the human voice is converted into an electrical signal by a microphone and fed via an amplifier and trigger circuit to one of the two inputs of a first timer, the switching time of which determines the snooze time.
  • the output signal of a second time switch is applied to the second input of the first time switch.
  • the alarm signal itself is generated by a loudspeaker, which is preceded by a tone oscillator and by a chopper, which in turn precedes it, and which makes the tonoscillator vibratable or non-vibratable for certain times (signal duration or pause duration).
  • the chopper controls these times itself.
  • the signal then occurring at the output of the amplifier and trigger circuit prevents further transmission of the alarm signal by the first time switch holding the chopper for the snooze time in the state in which the tone oscillator cannot oscillate.
  • a disadvantage of this known alarm device is that it is not possible to use a continuous tone for the alarm signal, since in this case the alarm device would switch itself off. Even if this disadvantage is not considered to be very important, further circuitry complexity results from the fact that the device for interrupting the alarm signal must be deactivated during the actual signal delivery and must be activated again during the signal pauses. If the user of the alarm device wants to interrupt it with a short sound, there is the possibility that he is only emitting this sound during the deactivated state, which means that the alarm signal cannot be interrupted at all and therefore continues to be transmitted.
  • the known alarm device installed in a mains-operated alarm clock or appointment clock also has the disadvantage that it is continuously switched on, although it is only required for a few minutes during 24 hours. Because of the associated, compared to that for the advancement of the display device, for example by a stepping motor in an analog alarm clock, relatively high power consumption, the known alarm device could hardly be used in a battery-operated device, in particular an alarm clock or appointment clock.
  • Another disadvantage of the known alarm device is that, despite the abovementioned shortcomings, it is relatively complex to build from discrete components and is therefore too expensive to be used in a device that is relatively cheap to produce by mass production, such as an alarm clock that costs only a few DM 10. can be installed.
  • a first output of a monostable multivibrator is placed on a control input controlling the alarm signal of an integrated circuit of the alarm device, that the output signal of a rectifier is given to an input of the monostable multivibrator, which is first a filter and amplifier unit and before that Another microphone is connected upstream that the output of the integrated circuit, on which an alarm signal can be output, to both Alarm signal converter is placed as well at the input of a switching element, the switching element only applying the microphone and the filter and amplifier unit to their supply voltage when an alarm signal coming from the output of the integrated circuit is present at its input and that an acoustic signal picked up by the microphone Via the filter and amplifier unit and the rectifier, the monostable multivibrator is set in its astable state and the signal present at the control input is thereby inverted.
  • An alarm signal can also be emitted from the alarm device, at least for a time, if there is already talk of the alarm signal being triggered.
  • the technical solution for this can be that the filter and amplifier unit can only give an output signal some time after application of the supply voltage, which can be achieved in that a capacitor must first be charged to a certain charge so that the operating point of a of the filter and amplifier unit contained amplifier.
  • the alarm device can be designed in such a way that extraneous noises with frequencies that lie outside the frequency range of the fundamental tone of the human voice cannot interrupt or finally switch off the alarm signal.
  • the technical solution for this can be that the filter and amplifier unit contains a low-pass filter or a high-pass filter, which acts above or below the frequency range of the fundamental tone of the human voice.
  • the monostable multivibrator can be designed in such a way that it has negligible energy consumption in its stable state.
  • the tech African solution for this may be that the monostable multivibrator has two transistors, which are both turned on only in the astable state of the monostable multivibrator, while in the stable state both transistors are not turned on.
  • the alarm device can also be equipped with a lighting device which then illuminates a display device for some time when the alarm signal emitted by the alarm device has been interrupted or finally switched off by the human voice.
  • the technical solution for this can be that a second output of the monostable multivibrator outputting a signal inverted to the first output is connected to a lighting device.
  • an alarm trigger switch 12 In front of the connection 4 of the IC 5 there is, on the one hand, an alarm trigger switch 12, the two positions of which are controlled by an alarm control device (not shown here), that is to say in the exemplary embodiment by an alarm clock or time clock.
  • the connection 4 is preceded by an alarm standby switch 20 which can be opened and closed manually by the user of the watch, the alarm device being ready for operation only in the closed switch position. If the alarm trigger switch 12 has also been closed by the alarm control device when the alarm standby switch 20 is closed, the signal present at an output 15 of a monostable multivibrator (monoflop) 7 is present at connection 4 of the IC 5.
  • the electroacoustic transducer 10 then emits, depending on whether the driver signal present at the output 6 of the IC 5 consists of an uninterrupted or an intermittent pulse sequence, a continuous or an intermittent acoustic alarm or wake-up signal with a specific alarm signal frequency.
  • the microphone 1 and the filter and amplifier unit 2 are only connected to the power supply during the alarm signal delivery, it contributes to further energy savings that the monoflop 7 due to its circuitry (FIG. 2) only then a non-negligible Power consumption when it is in its astable state.
  • the user can temporarily interrupt the alarm signal by amplifying acoustic vibrations in the filter and amplifier unit 2 and picked up by the microphone 1, generated by the human voice an output signal is emitted to a rectifier 3, which in turn is connected to an input 22 of the monoflop 7. If there is a sufficiently large signal at the input 22, the monoflop 7 switches to the astable state, that is to say an L signal at the output 15 and an H signal at the output 16. As a result, there is no driver signal for the electroacoustic transducer at terminal 6 of the IC more is pending, so the alarm signal is interrupted. At the same time, the L signal at the output 15 is given to a further input 14 of the switching element 9.
  • the switching element 9 is designed so that the connection of the voltage supply is interrupted immediately. Due to the H signal now present at connection 16, a lamp 8 connected between connection 16 and ground lights up, which serves to illuminate a display device, not shown.
  • the switching element 9 is designed so that the connection of the supply voltage to the microphone 1 and the filter and amplifier unit 2 remains longer, here for example about 10 seconds when the alarm signal pause of three seconds in the intermittent alarm signal continues. This ensures that the microphone 1 and the filter and amplifier unit 2 are functional and the alarm signal can be interrupted even during the signal pause, the intermittent alarm signal.
  • the filter and amplifier unit 2 is designed so that, with the supply voltage applied to it, it still takes a start-up time of a few seconds before a signal coming from the microphone 1 can be amplified at all. This ensures that the alarm device in any case emits an alarm signal for a few seconds, even if there is already talk, which is the case, for example, when an appointment clock containing the alarm device according to the invention is used during a meeting.
  • the filter and amplifier unit 2 is designed (Fig. 2 and 3) that both the frequency of the alarm signal of 2048 Hz completely and noises with a frequency below about 100 Hz are largely filtered out.
  • the time during which the monoflop 5 remains in its astable state when it changes state for the first time and during which the lamp 8 is on can be approximately 5 seconds. Subsequent changes of state of the monoflop 7 would be possible in significantly shorter time intervals due to its switching (see FIG. 2).
  • the immediate interruption of the power supply by the L signal at the input 14 of the switching element 9 ensures that the lamp 20 is not switched on and off a few times when the monoflop 7 returns to its stable position and 1 further acoustic signals are recorded by the microphone. Such switching on and off would be associated with an undesirably high power consumption.
  • the IC 5 can also be constructed in such a way that no wake-up process is carried out and the alarm signal can therefore only be finally switched off by the human voice.
  • a signal in the form of continuous or interrupted pulse trains is output at the output 6 only for a certain time, for example again for two minutes, if the breathing trigger switch 12 has been closed by the alarm clock or appointment clock and therefore an H at input 4 Signal is present. If the signal at input 4 changes from H to L during this time by an acoustic signal received by microphone 1 or by manually opening alarm standby switch 20, the signal at output 6 is switched off prematurely.
  • the alarm standby switch 20 is closed, pulse trains only appear again at the output 6 when the alarm trigger switch 12 has been opened again by the alarm clock or appointment clock and closed again. This happens after 12 or 24 hours with the usual alarm clocks or appointment clocks.
  • the lamp 8 for illuminating the display device can also be switched on during the time in which the monoflop 7 is in its stable position by manual actuation of the key switch 21.
  • an L signal is simultaneously applied to the input 4 of the IC 5. Therefore, the alarm signal can also be manually interrupted or finally switched off with the key switch 21.
  • a capacitor 64 is charged via a diode 63 and a zener diode 62.
  • An n-p-n transistor 69 is connected through two resistors 67 and 68 connected in parallel with the capacitor 64, which means that a transistor 72 is also connected through a further resistor 70.
  • a diode 65 connected to the terminal 18 and the positive electrode of the capacitor 64 limits the voltage to which the capacitor 64 can be charged.
  • a capacitor 73 is charged, with the result that the microphone 1 and the filter and amplifier unit 2 are supplied with voltage, that is to say that the output 17 and the Input 18 of the switching element 9 are interconnected.
  • the amplifier part of the filter and amplifier unit 2 consists of a three-stage transistor amplifier in an emitter circuit with three transistors 39, 41 and 43 and the collector resistors 40, 42 and 44, the collector of the upstream transistor being connected to the base of the downstream transistor.
  • the collector voltage of the transistor 43 is connected to the base of the transistor 39 via two resistors 47 and 38 connected in series, which leads to negative feedback.
  • a capacitor 45 and a resistor 46 are connected in series between the connection point of the resistors 47 and 38 and the ground of the DC voltage source.
  • the start-up time of the filter and amplifier unit 2 arises from the fact that after the voltage has been applied to the output 17 of the switching element 9, the capacitor 45 is first charged to this extent via the resistors 44, 47 and 46 must be that the operating point is set and thus the three-stage transistor amplifier is operational.
  • the microphone 1 for example an electret condenser microphone with built-in impedance converter, is connected with one connection to ground and with its other connection via a load resistor 32 to the output 17 of the switching element 9.
  • the AC voltage signal generated by the microphone 1 is fed to the base of the first transistor 39 of the amplifier via a filter, the components 33-37 and the effect of which will be described in connection with FIG. 3 below.
  • a capacitor 49 is used on the one hand positive Hall wave via a diode 50 in the rectifier 3 and the other with the negative Hall wave via the base emitter diode of a transistor 51.
  • the transistor 51 becomes conductive and therefore a capacitor 52 is charged in stages. At the same time, this capacitor 52 is discharged again via a resistor 53 in parallel with it. If, in the unit of time, more charge flows through the transistor 51 to the capacitor 52 than it emits through the resistor, then there is a sufficient voltage at the base of a transistor 55, which is connected via a resistor 54 to the positive electrode of the capacitor 52 so that transistor 55 turns on.
  • the monostable behavior of the monoflop 7 is achieved via a series circuit comprising a resistor 56 and a capacitor 57 based on the transistor 51.
  • the two transistors 51 and 55 are not turned on in the stable state of the monoflop 7, while both transistors are turned on in the astable state.
  • the monoflop 7 has an appreciable energy consumption only during the comparatively very short times of its unstable state.
  • the transistor 55 switches on, an L signal is applied to the input 4 of the IC 5 when the alarm standby switch 20 and alarm trigger switch 12 are closed, and the alarm signal is thus interrupted or finally switched off.
  • the capacitor 64 is discharged via a diode 66. This separates the filter and amplifier unit 2 and the microphone 1 from the supply voltage.
  • a transistor 60 is also turned on via a resistor 59, with the result that the lamp 8 lights up.
  • a resistor 61 which lies between the collector of transistor 60 and the base of transistor 55, improves the switching behavior of the monoflop 7 through feedback.
  • FIG. 3 schematically shows a spectrum 24 of the human voice with a spectrum 25 of the electroacoustic transducer 10 and a filter curve 23 with four areas I-IV. This filter curve is achieved by the filter part of the filter and amplifier unit 2.
  • a resistor 33 which is connected on the one hand to the connection point between the microphone 1 and the resistor 32, is on the other hand connected to the one connection of a resistor 35.
  • a capacitor 34 is connected to ground between the connection point of the resistors 33 and 35.
  • the other connection of the resistor 35 is connected both to the input 17 via a capacitor 36 and to the base of the transistor 39 via a capacitor 37.
  • Resistors 33 and 35 and capacitors 34 and 36 form a two-pole low-pass filter with a cut-off frequency of approximately 500 Hz, i.e. this low pass works in area III.
  • the capacitor 37 and the resistor 38 form a high-pass filter with a cut-off frequency of about 100 Hz, i.e. this high pass acts in area I.
  • area II which lies between areas I and III and corresponds to the frequency range of the human voice, there is no attenuation of signals. In contrast, disturbing noises outside this area II are attenuated.
  • a capacitor 48 which is connected to ground by the collector of transistor 43, in such a way that the capacitor 48 at a amplified AC voltage is quickly discharged via transistor 43 during the negative half-wave, but is charged relatively slowly via resistor 44 in the positive half-wave.
  • This sawtooth voltage is no longer sufficient above a frequency of about 1 KHz to control the rectifier 3.
  • Higher frequencies in the IV range such as the frequency of the electroacoustic transducer, cannot therefore interrupt the alarm signal or turn it off permanently.
  • the filter effect described with reference to FIG. 3 could also be achieved by a digital filter in the event that the block diagram shown in FIG. 1 is largely implemented in the form of an integrated circuit.
