Abstract

A front resonator for a speaker of a wireless device is provided, comprising: an enclosure mounted over the speaker and forming with an upper surface of the speaker a front volume for the front resonator; and a plate having an upper surface mounted to an inner surface of the enclosure, the upper surface of the plate having a trough with an opening formed therein, wherein the trough and the inner surface of the enclosure form a tube having at least one end to emit sound generated by the speaker through the front volume and tube from the wireless device.
