electromagnetic transduction device (s) (noun), electromagnetic transduction devices (pl)
Instruments that consist of a magnet, generally rare earth (either samarium cobalt or neodymium iron boron), and an energizing coil.

The magnet is attached to the ossicular chain (any of certain small bones, as those of the middle ear), tympanic membrane, or the inner ear (round window or fenestra).

A fluctuating magnetic field is generated when the coil is energized by a signal, which corresponds to an acoustic input and this magnetic field causes the magnet to vibrate.

The vibrating magnet, in turn, causes movement of either the ossicular chain or the cochlear fluids directly.

The force generated is inversely proportional to the square of the distance between the coil and magnet (e.g., doubling the distance between the magnet and coil results in an output of one-fourth the force); therefore, these two components must be maintained in close proximity to one another to realize an efficient system.

electromechanical transduction (s) (noun), electromechanical transductions (pl)
A variation of electromagnetic transduction.

In electromagnetic devices, it is often difficult to control the spatial relationship of the magnet and coil.

Because the magnet is attached to one portion of the anatomy and the coil attached to another part, the patient may observe a wide variation in performance.

As the relationship between the coil and the magnet changes, it results in a variance of the frequency response and a significant fluctuation of output levels.

An electromechanical device has an energizing coil and a magnet that are housed within an assembly which optimizes spatial and geometric relationships in order to avoid variability.

The electromechanical transducer directly connects to the ossicular chain (any of certain small bones, as those of the middle ear) to transmit the mechanical energy that is produced.
