1. A receptacle for storage of an object, comprising:

  • a proximity sensor configured to detect an action by a user close to or in contact with a surface of the receptacle;

    a transducer;

    a control circuit coupled to the proximity sensor and to the transducer, the control circuit being configured to generate a control signal to the transducer when a user action is detected by the proximity sensor; and

    an unpacking detector coupled to the control circuit and configured to detect removal of the receptacle from a packaging,wherein upon detection of removal of the receptacle from the packaging by the unpacking detector, the control circuit is further configured to switch from a standby mode during which the control circuit periodically awakens to query the unpacking detector to a detection mode during which the control circuit periodically checks a state of the proximity sensor,in the standby mode, the control circuit changes a length of an awake period during which it awakens to query the unpacking detector, andwherein the control circuit is also configured to progressively reduce the awake period to query the unpacking detector, in the standby mode.
