摘要： An ultrasound transducer for an electronic device, including a housing and an ultrasonic transducer element integrated with the housing. The transducer element is capable of operating in at least one of a receiver mode and transmitter mode. In the receiver mode, the transducer element produces an electrical signal in response to an impinging acoustic signal. In the transmitter mode, the transducer element produces an acoustic signal in response to an electrical signal applied thereto. The housing has at least one surface which ensures mechanical stressing of the transducer element in a manner which causes the transducer element to produce the signals.

摘要： A piezoelectrically actuated liquid atomizer device which applies alternating voltages from an ordinary wall outlet to a piezoelectric actuator intermittently and at a high rate sufficient to cause an atomization plate which is vibrated by the actuator to form small droplets from liquid which is supplied to the plate. The intermittent application of voltages to the piezoelectric actuator is carried out according to a duty cycle in which the off times are adjustable. An override of the duty cycle is provided so that the piezoelectric actuator operates continuously for intervals which are manually or automatically controlled.
