The simplest form of transducer from an electric signal to sound waves is by way of a small electro-dynamic transducer - really a tiny loudspeaker. But of course any transducer between these energy types can be used. Piezoelectric, capacitance, and so on.
Your doctor's stethoscope does not have magnetic earpieces, nor do the earpieces used to communicate with the patient in CT or MRI scans.
In the latter case, the metal would seriously interfere with the diagnostic process, and the solution is to have the audio transducer remote, and to connect that to the patients earpiece with plastic tubing. Quite like the speaking tubes on older ships - simple but reliable.

What is the difference between a weakly magnetised nail and a strongly magnetised nail?
The strong magnetised nail will pick up more paper clips than the weak magnetised nail.That is because the strong magnetised nail is getting more strength and that means that the weak magnetised nail is getting less strength.in a steel nail there are these things called domains, in a weakly magnetised nail some of them will be pointing north, south, east and west, but however in a strongly magnetised nail all the domains will point to north.
Can iron be magnetised?

What does de-magnetised mean?

What happens when a magnetic material is magnetised?

Will a magnetized screwdriver attrat steel screws?

What is the difference between a weakly magnetised nail and a strongly magnetised nails?
A Weakly magnetised nail will pick up less paper clips then a highly magnetised nail, Hope That Helps:)
What can be magnetised?
ferro magnetic substances can be magnetised. but it is not necessary that all the Ferro magnetic substances can be permanently magnetised. it depends on the alignment of domains in the substance.for example wrought iron can be magnetised permanently but soft iron can only be magnetised temporarily(Electro Magnets).
Do bands wear earpieces while playing?
no，i think. Yes many performers wear earpieces when they play. Some just to limit the intense sound levels on stage some have active earpieces which give them a mix of the music.

Are there different sizes of cellphone earpieces?
No, they normally come one size fits all, however there are companies that offer custom molded earpieces.
In what direction should the earpieces of the stethoscope be pointed?
In the ear
How would you determine if a metal is magnetised?
You can put a magnet near the metal. If it gets attracted or repelled, then it is magnetised
Can wood be magnetised partially?
No.
What materials are nonmagnetized?
Diamagnetic substances are not magnetised. Example: water is a diamagnetic substance, so it cannot be magnetised by any means.
What is the diffrent between a magnetised steel nail and an unmagnetised steel nail?
