Do completely passive loudspeakers require a CE Mark? If yes, what standards
would be used to declare conformity?
My initial answer to this question was NO. Except for the recast RoHS
Directive now requiring a CE Mark.
The EMC Directive - Chapter 1, Article 1, Section 3 says:
3. This Directive shall not apply to equipment the inherent nature of
the
physical characteristics of which is such that:
(a) it is incapable of generating or contributing to electromagnetic
emissions which exceed a level allowing radio and telecommunication equipment
and other equipment to operate as intended; and
(b) it will operate without unacceptable degradation in the presence of
the
electromagnetic disturbance normally consequent upon its intended use.
So that would seem to be a no.
The Low Voltage Directive - Article 1 says:
For the purposes of this Directive, ‘electrical equipment’ means any
equipment designed for use with a voltage rating of between 50 and 1 000 V for
alternating current and between 75 and 1 500 V for direct current, other than
the equipment and phenomena listed in Annex II.
My initial thought here was that this would also not apply. But, some audio
amps can put out audio signals exceeding 50 V. The question here is - when
they use the term alternating current here, does that mean AC Mains only or
can that also include the varying audio signals a speaker would see? The DC
part is easy, most speakers do not work well with DC applied.
Hoping to either learn something or settle an argument, your input is
appreciated as always.

Scott
