ABSTRACT:
A microphone is provided for converting the impact force of a moving charged droplet into a corresponding electrical signal. A vertical support member supports a diaphragm in the path of the moving droplet. The diaphragm flexes or vibrates in response to a group of impinging droplets. A bimorph piezo-electric element is in contact with the diaphragm to move therewith and is fixedly secured at its opposite end to an adjacent housing member. The bimorph generates an electrical signal in response to bending stresses created when the bimorph is bent.
