alternative generation of ultrasound waves
Posted by: kostas papas , E-mail: lakourtis@hotmail.com, on December 17, 2004 at 23:43 :
The use of piezoelectric transducers is well spread for the generation and receive of ultrasound waves. The use of microphones is also an existing technique for receiving acoustic and ultrasonic waves.
However what about microphone-speaker technology to generate and transmit ultrasound waves through solid material?
Is mechanical coupling (efficiency coef) a problem when generating waves by means of speakers?
This is an academic question that was brought about after using piezoelectric transducers.
