Extremely popular devices in the field of’home entertainment, Bluetooth speakers are able to reconcile a good degree of practicality and a qualitative rendering of audio reproduction consistent with the expectations related to the product.
Their clear affirmation on the market is due to the practicality of the exchange of digital data at a short distance with extremely low battery consumption compared to other technologies. Bluetooth speakers – rechargeable via PC or car, now able to connect to the various virtual assistants of a smart home – present themselves as an efficient audio choice on the market, combining power, cost, lightness and practicality.
The operation of Bluetooth speakers
Bluetooth speakers, or more precisely loudspeakers, receive the signal from the apparatus to which they are connected by radio waves – the Bluetooth system itself – amplifying it in relation to the power they can develop.
Bluetooth speakers can generally accommodate an analog audio input and various Hi-Fi components at the discretion of the model. Bluetooth operates in ISM band 2.45 GHz (2400-2483.5 Mhz), feature that connotes it as a technology with reduced interference, stable and ideal for transmitting low-range signals.
Technology Wi-Fi, main competitor in terms of audio choice, allows you to transport more data and in large spaces, but it needs theinstalling a local network to connect all affected devices.
Bluetooth speakers and CE marking
Like all electrical and electronic equipment, Bluetooth speakers – but also headphones and earphones that use the same technology – must bear the CE marking and comply with the standards defined by the various directives.
As it is known, CE marking guarantees the consumer the conformity of the product same to all the provisions of the European Community, in terms of health protection, safety and environmental protection. L’obtaining the CE marking for Bluetooth loudspeakers – which primarily involves the figure of the manufacturer, but at different levels the figures of authorized representative, importer and distributor – is divided into various phases.
It starts from the identification of the requirements necessary to comply with the directives of the European Community, to then proceed to their verification. L’application of harmonised standards comprehensively it is the easiest and least expensive route to assess product compliance and, once the verification phase has been completed, the technical file is prepared.
The technical file looks like a collector of all the documentation necessary to identify the product, in this case the Bluetooth speakers, and certify their compliance with the requirements of the applicable Directives. Once this phase is completed, the CE mark is placed, visibly, legible and indelible. At the end of the process there is the drafting of the EU Declaration of Conformity indicating that the product conforms to all legal requirements.
What obligations for MANUFACTURER, IMPORTER and DISTRIBUTOR
As mentioned, the figure of the manufacturer is the one most involved at an operational and bureaucratic level in the evaluation process, verification and control of product conformity. He will take care of making draw up the EU Declaration of Conformity, preparing the technical file and keeping all the documentation for 10 years. It is the obligation of the manufacturer affix the CE mark, but also the development of Corrective to ensure that the product complies with European directives throughout its life.
L’importer must verify that the product imported by him is equipped with CE Certificate of Conformity; has traceability documentation and must ensure that, the period of time when the product is under its responsibility, is not modified so that it can jeopardize its compliance, informing the manufacturer and the supervisory authorities if he accesses.
The distributor, analogously, has an obligation to ensure that the conformity of the products lasts over time and that there are no changes whatsoever, endeavouring to point out any inconsistencies.
