Latest Patents

One of John Parkes' most recognized patents is for a sound generator. This invention features an open-ended can with a piezoelectric crystal attached to its closed end face. Inside the can, there is a battery supply and circuitry designed to cause the can to resonate. The open end of the can is connected to a backboard through a ring of closed-cell foamed synthetic plastics material, creating a waterproof enclosure for the battery and circuitry. The circuitry utilizes one or more CMOS integrated circuits, which are configured to form oscillators. One of these oscillators pulses the crystal through a transistor power amplifier and step-up transformer. The oscillator can be adjusted off the resonant frequency to reduce the output, or a feedback path can be provided to lock the oscillator onto a resonant frequency.
