moving coil

In 1923 the first practical moving coil microphone was built.

Moving coil instruments respond only to the average value of the current through them.

A moving coil meter has a different and equally distinctive structure.

Separation of the two moving coils is usually from 10 to 30 metres.

The complexity and thus cost are both high compared to standard moving coil speakers.

It can be either of the moving coil or moving magnet type.

Other possible detectors could be moving coil or surface acoustic wave.

Its moving coils shocked my skin and, startled, I went back to the sticks for one more attempt.

These are all of the moving coil type, in order to keep mass, and thus access times, as low as possible.

These enjoyed brief success but were quickly eclipsed by moving coil speakers.

Many digital voltmeters and all moving coil meters are in this category.

In these systems, the projectile is accelerated by a moving coil "armature".

The phase angle varies most near resonance in moving coil loudspeakers.

However the quality of a moving coil equipped set can be pleasant, and mistakable for a modern portable radio.

The two moving coils, A and B, are connected in parallel with the circuit load.

The moving coil galvanometer is practically immune to ambient magnetic fields.

Moving coil phonograph cartridges produce a very small voltage.

1987, their first moving coil phono cartridge, the Shiraz, was launched.

A moving coil meter indicates the average (mean) of a varying current through it, which is zero for AC.

Introduced in 1963, the 3300 was a 300 line per minute drum printer that used a moving coil actuator for the print hammer.

Various models were made including ones with condensor diaphragms, ribbons, moving coils, and carbon buttons.

The better moving coil speakers were available from 1925, but like most new and better technologies they were relatively expensive.

Instruments with moving coils can be calibrated for direct current or power frequency currents up to a few hundred Hz.

In analog devices, three moving coil elements are mounted in an orthogonal arrangement within a single case.
