Abstract

See full text

A two-port air pump speaker that includes at least two active, phase-modulated, bi-directional shutters and an ultrasonic pumping chamber having at least two ports; a first port facing towards the listener, the forward port, and a second port facing another direction, the backward port which may be behind an acoustic baffle or inside a speaker enclosure. A two-port speaker with two active steering shutters can create continuous bi-directional airflow which leads to low distortion reproduction of low audio frequencies. The same improved design can be used also for other applications where acoustic modulation is required, especially in ultrasonic frequencies.
