Portable multimedia equipment - Determination of battery duration - Part 3: Wearable powered loudspeaker equipment

IEC 63296-3:2025 specifies the method for measuring the battery duration at a defined sound pressure level for continuous music playback of battery-operated wearable powered loudspeaker equipment. A primary battery or secondary battery can be used as a power source for such a shoulder-carried or body-worn loudspeaker and its composite device. In addition, only equipment that can be placed on or hung from a head and torso simulator (HATS) is covered. Bone conduction speakers are excluded. Portable loudspeaker equipment also supporting video playback as the main function is not covered by this document.

Tragbare Multimedia Einrichtungen - Festlegung der Batterielebensdauer - Teil 3: Tragbare elektrisch angetriebene Lautsprecher Einrichtungen

Matériel multimédia portable - Détermination de la durée des batteries - Partie 3: Haut-parleurs portables alimentés par batteries

IEC 63296-3:2025 spécifie la méthode de mesure de la durée des batteries à un niveau de pression acoustique défini pour la lecture continue de fichiers musicaux par des haut-parleurs portables alimentés par batteries. Une pile ou une batterie d'accumulateurs peut être utilisée comme source d'énergie pour un tel haut-parleur porté sur l'épaule ou sur le corps et son dispositif d'interconnexion. De plus, seul le matériel qui peut être placé sur ou suspendu à un simulateur de tête et de torse (HATS - head and torso simulator en anglais) est couvert. Les haut-parleurs à conduction osseuse sont exclus. Les haut-parleurs portables dont la fonction principale est la lecture vidéo ne sont pas couverts par le présent document.

53 FOREWORD
54 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
55 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
56 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
57 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
58 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
59 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
60 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
61 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
62 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
63 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
64 consensus of opinion on the relevant subjects since each technical committee has representation from all
65 interested IEC National Committees.
66 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
67 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
68 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
69 misinterpretation by any end user.
70 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
71 transparently to the maximum extent possible in their national and regional publications. Any divergence between
72 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
73 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
74 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
75 services carried out by independent certification bodies.
76 6) All users should ensure that they have the latest edition of this publication.
77 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
78 members of its technical committees and IEC National Committees for any personal injury, property damage or
79 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
80 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
81 Publications.
82 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
83 indispensable for the correct application of this publication.
84 9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
85 patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
86 respect thereof. As of the date of publication of this document, IEC had not received notice of a patent, which
87 may be required to implement this document. However, implementers are cautioned that this may not represent
88 the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
89 shall not be held responsible for identifying any or all such patent rights.
90 IEC 63296-3 has been prepared by subcommittee TA19: Environmental and energy aspects for
91 multimedia systems and equipment, of IEC technical committee TC100: Audio, video and
92 multimedia systems and equipment. It is an International Standard.
93 The text of this International Standard is based on the following documents:

114 body and its composite device.
115 IEC 63296 series on ‘Portable multimedia equipment – Determination of battery duration’
116 currently consists of the following planned or published parts:
117 – Part 1: Powered loudspeaker equipment
118 – Part 2: Headphones and earphones with active noise-cancelling functions
