Abstract
The object of the invention is a particular accessory and an arrangement for a mobile phone (5) and its hands-free function, for instance in a car. Thanks to the accessory, such as a cradle (16), the characteristics of the mobile phone (5) are changed, preferably for the hands-free function, due a strip (17) which covers at least one of the at least two sound openings (7A, 7B) of the pressure gradient microphone (7) of the mobile phone. The sound opening can be covered also by a special flange of an accessory connector, or by a separate bridge mounted in the cradle. The covering can also be sealed with a rubber seal, for instance.
