A retractable pen mechanism is mounted on the distal end of the pen body, and a microphone transducer and speaker transducer are mounted at the proximal end. The speaker transducer is transversely mounted across an open proximal end of the pen body so that the interior of the pen body acts as a resonator improving the sound quality of the speaker.
