Extremely popular devices in the field ofhome entertainment, Bluetooth speakers are able to combine a good degree of practicality and a qualitative rendering of audio reproduction consistent with the expectations linked to the product.
Their clear success on the market is due to the convenience of exchanging digital data over short distances with extremely low battery consumption compared to other technologies. Bluetooth technology 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.
How Bluetooth speakers work
Bluetooth speakers, or more precisely speakers, receive the signal from the device to which they are connected radio waves – the Bluetooth system itself – amplifying it in relation to the power they can develop.
Bluetooth speakers are generally able to accommodate an analog audio input and various Hi-Fi components at the discretion of the model. Bluetooth works in ISM band 2.45 GHz (2400-2483.5 Mhz), a characteristic that characterizes it as a technology with reduced interference, stable and ideal for transmitting short-range signals.
Technology Wifi, the main competitor in terms of audio choice, allows you to transport a greater quantity of data and in large spaces, but requires theinstallation of a local network to connect all the 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 is known, the CE marking guarantees the consumer the conformity of the product itself 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.
We start from the identification of the requirements necessary to comply with the European Community directives, to then proceed with their verification. L'application of harmonized standards in a complete way it is the simplest and least expensive path to evaluate the conformity of the products and, once the verification phase is concluded, the technical file is prepared.
The technical file presents itself as a collector of all the documentation necessary to identify the product, in this case the Bluetooth speakers, and certify its compliance with the requirements of the applicable directives. Once this phase is completed, the CE mark is positioned in a visible, legible and indelible manner. At the end of the process there is the drafting of the EU Declaration of Conformity which indicates the conformity of the product with all legal requirements.
What obligations for MANUFACTURER, IMPORTER and DISTRIBUTOR
As mentioned, the figure of manufacturer it is the one most involved at an operational and bureaucratic level in the process of evaluating, verifying and controlling product conformity. He will take care of it draw up the EU Declaration of Conformity, preparing the technical file and keeping all the documentation for 10 years. It is the manufacturer's obligation affix the CE mark, but also the development of corrective actions 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 the documentation for traceability and must ensure that, during the period in which the product is under its responsibility, it is not modified in a way that could jeopardize its conformity, informing the manufacturer and the supervisory authorities if this happens .
The distributor, similarly, has the obligation to ensure that the conformity of the products lasts over time and that no changes of any kind occur, making every effort to report any inconsistencies.
