Abstract: An audio device comprises an acoustic transducer or speaker with a bidirectional vent coordinating between the front and back of the speaker. The bidirectional vent provides a balanced impedance in both the push/pull conditions of the speaker excursions while minimizing listener fatigue, without the need for a separate external vent or separate pressure management material. The audio device may include dual sound ports which have different dimensions, that may be selected to tune the response curve of the audio device, and to create smooth transitions of pneumatic pressure between the ear canal and the speaker.

Abstract: A head-worn sound reproduction device is provided in the form of left and right earphones, which can either be clipped to each ear or mounted on other headgear. The earphones deliver high fidelity audio to a user's eardrums from near-ear range, in a lightweight form factor that is fully “non-blocking” (allows coupling in and natural hearing of ambient sound). Each earphone has a woofer component that produces bass frequencies, and a tweeter component that produces treble frequencies. The woofer outputs the bass frequencies from a position close to the ear canal, while the tweeter outputs treble frequencies from a position that is either close to the ear canal or further away. In certain embodiments, the tweeter is significantly further from the ear canal than the woofer, leading to a more expansive perceived “sound stage”, but still with a “pure” listening experience.

Abstract: In an earpiece 10 of the present invention, mainly, a plug section 15 is fitted into a sound channel space 13A of a central tube section 13, and the plug section 15 is formed with a sound channel long hole 15B penetrating in a longitudinal direction thereof and sound channel short holes 15G penetrating in lateral directions thereof. With this structure, a very small part of sound transmitted from a stem section 12 is directly transmitted to the eardrum through an aperture 15A, but most of the sound transmitted from the stem section 12 is directly transmitted via an internal space 20 to the eardrum. Then, the user perceives the sound having detoured as indirect sound that comes from the front of himself/herself with a time difference, and thereby can feel out-of-head sound localization and sound spread, thereby experiencing a sense of direction from the front and realistic sensation.
