What is BS EN IEC 63034 about?    BS EN IEC 63034 discusses micro speakers. Micro speakers are used in smart devices such as phones, tablets, headphones, and hearing aids. BS EN IEC 63034 specifies the characteristics of micro speakers as well as the relevant test methods for micro speakers 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.   Who is BS EN IEC 63034 for?   BS EN IEC 63034 on micro speakers is useful for:   Smartphone manufacturers    Bluetooth speaker manufacturers

What is BS EN IEC 60268-4 - Sound system equipment about?    BS EN IEC 60268-4 is the fourth part of the BS EN IEC 60268 multi-series that focuses on sound system equipment. BS EN IEC 60268-4 specifies methods of measurement for the electrical impedance, sensitivity, directional response pattern, dynamic range, and external influences of sound system microphones, and also details the characteristics to be specified by the manufacturer. BS EN IEC 60268-4 applies to sound system microphones for all applications for speech and music. BS EN IEC 60268-4 applies to each audio channel of microphones having more than one channel, for example for stereo or similar use.

NEW! IEC 60268-4:2018 is available as IEC 60268-4:2018 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60268-4:2018 specifies methods of measurement for the electrical impedance, sensitivity, directional response pattern, dynamic range and external influences of sound system microphones, and also details the characteristics to be specified by the manufacturer. It applies to sound system microphones for all applications for speech and music. It does not apply to measurement microphones, but it does apply to each audio channel of microphones having more than one channel, for example for stereo or similar use. It is also applicable to flush-mounted microphones and to the analogue characteristics of microphones with digital audio output. For the purposes of this International Standard, a microphone includes all such devices as transformers, pre-amplifiers, or other elements that form an integral part of the microphone, up to the output terminals specified by the manufacturer. The major characteristics of a microphone are considered in Clauses 6 to 21. Additional characteristics are considered in Annex A and Annex C. IEC 60268-4:2018 cancels and replaces the fifth edition published in 2014. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) subclause 19.4 on "pop" measurement replaces Annex C; b) new Annex D for noise measurements in the digital domain.

The major characteristics of a microphone are considered in Clauses 6 to 21. Additional characteristics are considered in Annex A and Annex C. NOTE The characteristics specified in this document do not describe the subjective response of the microphone. Further work is necessary to find new definitions and measurement procedures for a later introduction of objective characteristics for at least some of the subjective descriptions used to describe microphone performance.
