Published By Publication Date Number of Pages
JIS 2016-11-21 19
]]> This Standard specifies electrodynamic horn type loudspeakers, which are used for general voice amplifiers in telecommunications equipment (hereafter referred to as loudspeakers).

This Standard is not applicable to loudspeakers employing cone speakers as the driver.

NOTE: Loudspeaker means equipment composed of horn and drive unit (hereafter referred to as unit).

Loudspeakers integrated into one body are called combination type, and loudspeakers whose horn and units are separable are called separate type.

Published By Publication Date Number of Pages
IEC 2021-07-12 34
]]> IEC 63296-1:2021 specifies the methods for measuring the battery duration at defined sound pressure levels for continuous music playback of battery-powered loudspeaker equipment. A primary battery or secondary battery can be used as a power source for the loudspeaker and its composite equipment. In the case of composite equipment, this method for the measurement of battery duration can be applied under the condition of powered loudspeaker playback only.

IEC 2020-06-24 92
]]> IEC 63034:2020 specifies the characteristics of microspeakers as well as the relevant test methods on microspeakers using steady-state sinusoidal signals, sinusoidal chirp, multi-tone or noise. The main characteristics include, but are not limited to, impedance, displacement, amplitude frequency response, distortion, and power handling.

Published By Publication Date Number of Pages
IEC 2010-01-27 28
]]> IEC 62458:2010(E) applies to transducers such as loudspeaker drive units, loudspeaker systems, headphones, micro-speakers, shakers and other actuators using either an electro-dynamical or electro-magnetic motor coupled with a mechanical suspension. The large signal behaviour of the transducer is modelled by a lumped parameter model considering dominant nonlinearities such as force factor, stiffness and inductance. It defines the basic terms and parameters of the model, the methods of measurements and the way the results should be reported. It cancels and replaces IEC/PAS 62458 published in 2006. It constitutes a technical revision. The main changes are:
– descriptions of the methods of measurement are adjusted to the state of the technology;
– addition of Clauses 4 to 15;
– integration of Annex A in the main body of the standard;
– overall textual review.
