Method and system for assembling the digital pen.

A digital pen (1000) comprising: an electrical circuit (110); an acoustic transmitter (100) spaced from said electrical circuit (110), and configured to transmit acoustic signals, said acoustic transmitter (100) an ultrasonic transducer and acoustic signals being said ultrasonic signals; and characterized by a resilient support (120, 250), configured to mechanically press said electric circuit (110) for establishing an electrical connection with said transmitter upon applying a mechanical pressure applied to said resilient support (120, 250) on a body pen by a pen housing, comprising said resilient support (120, 250) a base extending longitudinally along said boom, presented the resilient support a stability that allows easy assembly by sliding position of the support resilient (120, 250), rising extensions perpendicularly from each side of said base for securing said resilient holder (120, 250) to a body of said digital pen (1000), said acoustic transmitter (100) comprising a cylindrical transmitter ( 100) and a tape comprising said electrical circuit (110) having a flexible PCB, comprising resilient support (120, 250) one section ng transverse U-shaped and configured to confine a portion of said flexible PCB (110) and said tape within the pen housing.
