Why is ultrasound useful?

Can you produce ultrasound from a speaker by passing high frequency a.c. current through it?
Because at very high frequencies, the inductive effect of loud speaker coil is so high that practically no current passes through it. Further, the diaphragm of the loud speaker cannot respond for such high frequency. Hence ultrasonic waves cannot be produced using loud speaker.
What sounds bat produce?

How will a Doppler ultrasound reduce the need for caesarean section?

How does a stereo speaker use an electromagnet to produce sound?
An electromagnet drives the stereo speaker to provide the sound.
Do porpoises produce ultrasound?
Yes they do - in the form of high-pitched 'clicks'. Each "click" is a very short pulse or chirp of ultrasound. (A pure 'click' is merely a transient.)
