1. A digital pen comprising:

  • an electric circuit;

    an acoustic transmitter, detached from said electric circuit, and configured to transmit acoustic signals, said acoustic transmitter being an ultrasound transmitter and said acoustic signals being ultrasound signals; and

    a resilient holder, configured to mechanically press said electric circuit into secured electrical contact with said transmitter upon application of mechanical pressure applied on said resilient holder to a pen body by a pen housing, said resilient holder comprising a base longitudinally extended along said pen, the resilient holder having elasticity to enable easy assembly by sliding the resilient holder into position, extensions rising perpendicularly from either side of said base to secure said resilient holder to said pen body, said acoustic transmitter comprising a cylindrical transmitter and a ribbon, said electrical circuit comprising a flexible PCB, the resilient holder comprising a U shaped cross section and being configured for confinement of a part of said flexible PCB and said ribbon within the pen housing.
