发明名称 Device for achieving animal response
摘要 A device for achieving animal response that produces two output frequencies, one to soothe the animal and one to distress the animal. The frequency for distressing the animal is an oscillating frequency to cause further attention by the animal and to provide optimum operation of the sound-producing element. The oscillating frequency is created by producing a second frequency higher than the first frequency, and then oscillating this second frequency. Sound is produced by a piezoelectric element driven by these frequencies. Components are generally contained in an enclosure body, with push buttons for selecting a desired sound output penetrating this enclosure body for contact by a user of the device.
