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 radiographic procedure employs high frequency sound waves to produce an image?
Are known as: Overtones
What is the name of the speaker that used Ultra sound?
You can't produce ultra-sound from a normal speaker. There would be no current to drive the coil due to the high frequency. It would have to be an ultrasound transducer.
What medical device uses echoes of high-frequency sound waves to produce images?
an ultrasound
What imaging technique uses high-frequency sound waves to produce an image of the liver gallbladder or pancreas?
Ultrasound imagery (or sonography).
High voltage by itself does not produce electric shock What does?
The amount of current passing through your body and the path of the current.
What are ultrasound?
Is cyclic sound pressure with a frequency greater than the upper limit of human hearing. Ultrasound imaging is a common diagnostic medical procedure that uses high-frequency sound waves to produce dynamic images (sonograms) of organs, tissues, or blood flow inside the body.
Do giraffes produce ultrasound to communitate?
Actually, Giraffes communicate using infrasonic sounds, i.e. sounds with a frequency BELOW the range of human hearing. Ultrasound would be ABOVE the human hearing range.Sources: Wikipedia
How are ultrasound waves produced?
this is not how they are made naturally but how they are made for diagnostic uses: ultrasound waves are made by applying a current that is similar to the natural frequency of the piezoelectric quartz crystal, when this is applied to the crystal they produce ultrasonic waves! ADDED: As a point of detail, quartz is rarely if ever used now, replaced by much more sensitive, artificial, piezoelectric ceramics.
Do wolves produce ultrasound?
no
What is Ultrasound Scan An ultrasound scan is a diagnostic imaging technique that uses high-frequency sound waves to produce images of the internal organs and tissues in the body. The sound waves are transmitted through a device called a transducer?
Yes. it’s called a probe.
What does an Endorectal ultrasound produce?
A sonogram
Why not ultrasonic be produced by passing high frequency alternating current through speaker?
The ability of a speaker to produce ultrasonic output when driven with high frequency AC depends on the design (intent) of the speaker. Typical audio speakers are not designed to go ultrasonic - the cone's mass and resonate frequency just won't support it. Also, the coil reactance is too high for ultrasonic waves so they cannot be produced.
