Abstract: An earphone comprising an earphone housing having a wall comprising (1) a front side that joins (2) an end portion in which a primary sound output opening is formed, which joins (3) a face portion in which a secondary output opening is formed, which joins (4) a back side which joins the front side and encloses a driver, wherein the primary output opening is dimensioned to output sound generated by a diaphragm of the driver contained within the earphone housing into the ear and the secondary output opening is dimensioned to vent the ear to a surrounding environment, and wherein the primary output opening and the secondary output opening face different directions.

Abstract: An electronic device having an enclosure having a top panel and a bottom panel. An electromagnet is mounted within the enclosure, the electromagnet having a core portion attached to the top panel and a coil connected to the core portion. An attractor plate is attached to the bottom panel, the attractor plate forming part of a magnetic circuit of the electromagnet such that when an electrical audio signal is applied to the electromagnet, the bottom panel vibrates and produces a sound. A permanent magnet is further attached to the core portion, the permanent magnet is configured to create a bias in the magnetic circuit so as to modify a distortion in the sound.
