  • I CLOCK PULSE GENERATOR Fig.6 x U M LLL in CLOCK PULSE GENERATOR lnven/or: Ila-m G ammvm-Sdwr ELECTRONIC ARRANGEMENT FOR SIMULATING ANIMAL SOUNDS BACKGROUND OF THE INVENTION
  • the electronic apparatus applies tone generators in the form of preferably astable multivibrators to synthesize animal calls in the form of luring calls, warning calls or scare-off calls.
  • the repetition of the calls is controlled through pulses derived from a clock pulse generator.
  • pulse control multivibrators it is possible to produce sound spectrums of varying frequency, with simple circuit elements.
  • a clock pulse generator produces clock pulses which may be either integrated or differentiated for a portion of the pulse. These pulses are then applied to multivibrators of the astable type and transmitted to loud speakers through the use of power amplifiers. By partially integrating and/or differentiating the pulses, any desirable combination of audio signals may be produced.
  • FIG. 1a to 1d shows the integration and/or differentiation of a pulse, and the resulting frequency function which may be derived from such processing of the pulse, in accordance with the present invention

  • control pulse I produces in a multivibrator a constant tone frequency corresponding to the curve 2.
  • the curve 3 shows a control pulse which is partially integrated. This pulse produces in the multivibrator a tone signal that decreases in frequency as shown by the curve 4 in FIG. lb.
  • FIG. 1c shows a control pulse 5 which is partially differentiated. This pulse produces the frequency function corresponding to curve 6 within the sound spectrum.
  • the pulse 7 shown in FIG. 1d, is partially differentiated in the first interval 7. This pulse 7 is also partially integrated in the interval 7".
  • the tone or audiofrequency resulting from the pulse 7 is shown by curve 8. It is seen from this representation of the curves, that an audiofrequency function of any desired shape may be derived from these pulses.
  • a clock pulse generator transmits to the multivibrators pulses which are partially differentiated and/or partially integrated.
  • the pulses thus transmitted are of the desired duration and have the desired interval between pulses.
  • a sound function is realized which corresponds to a rising or falling animal cry, as described in the'relation to FIGS. la to 1d.
  • the noise effects applied to humans is maintained at a minimum and not bothersome.

  • a clock pulse generator 9 transmits to a multivibrator 10 pulses II which are partially integrated.
  • a modulated pulse I2 which is transmitted to one or more loud speakers 14, by way of a low frequency amplifier 13.
  • the multivibrator 10 is provided with a variable integration network. This integration network is connected between ground and the emitter electrodes of the transistors within the multivibrator (not shown). As a result of this adjustable type of network 15, the required audio function may be corrected with ease.
  • FIG. 3 shows a block schematic diagram for producing a signal function which simulates electronically a complicated cry of a wild bird of prey.
  • a cry with a hoarse character may, for example, be associated with the cry of a falcon.
  • a number of periodic pulses 16 are partially integrated after being emitted from the clock pulse generator 17. These pulses are then applied to a combination of three multivibrators I8, 19 and 20.
  • the main portion of the required audio spectrum is realized through a percent amplitude modulation of the second multivibrator 19. This is accomplished in conjunction with the first multivibrator 18.

  • a frequency within the range of 1.0 to 4.0 kHz. is applicable to the multivibrator 19.
  • the preferred value for the pulse timing factor is H5, and for the frequency the preferred value is 2.5 kHz.
  • the hoarse characteristic of the sound is produced by a third multivibrator 20 which is connected in parallel with the multivibrators 18 and 19.
  • the pulse timing factor is within the range of l/S to H2, and the frequency is within the range of 100 to 500 Hz.
  • the pulse timing factor is preferably H2 and the frequency is preferably 200 Hz.

  • the resulting ultrasonic frequency which is rapidly variable, is applied in the conventional manner to a loud speaker 30.
  • An amplifier 29 serves to amplify the signal in the usual manner, while the loud speaker 30 is made of the proper physical and structural characteristics and dimensions.
  • FIG. shows in block form an embodiment for synthetically producing audio sounds in the form of luring signals and scareoff signals.
