EN 62458:2011 音响系统设备 电声换能器 大信号参数的测量

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.

IEC 60268-7:2010(E), is applicable to headphones, headsets, earphones and earsets, intended to be used on, or in, the human ear. It also applies to equipment, such as pre-amplifiers, passive networks and power supplies which form an integral part of the headphone system. It specifies the characteristics which should be included by the manufacturer in specifications, and relevant methods of measurement. It includes a classification of the different types of earphone, mainly characterized by the way in which the transducer is coupled acoustically to the ear, and a classification code which may also be used for marking. cancels and replaces the second edition published in 1996, and constitutes a technical revision. This edition contains the following changes: - clause/subclause renumbering in accordance with ISO/IEC Directives, Part 2; - addition of a measurement system using HATS; - addition of details on pinna simulators for high measurement reproducibility, see Annex A.

IEC 62537:2010(E) specifies the requirements for a digital loudspeaker interface based on the IEC 60958 series of standards and the MIDI specification. It maximizes flexibility and value by combining these previously separate standards. Together, the two standards provide a simple and flexible digital interface for loudspeakers. Examples for applications of the interface can be found in Annex C of this standard.

IEC 62459:2010 音响系统设备.电声变换器.悬架配件的测量

This International Standard applies to the suspension parts of electroacoustic transducers (for example@ loudspeakers). It defines the parameters and measurement method to determine the properties of suspension parts like spiders@ surrounds@ diaphragms or cones before being assembled in the transducer. The measurement results are needed for engineering design purposes and for quality control. Furthermore@ this method is intended to improve the correlation of measurements between suspension-part manufacturers and loudspeaker manufacturers. The measurement methods provide parameters based on linear and nonlinear modelling of the suspension part and uses both static and dynamic techniques.
