International Classification:

H04R 1/20
H04R 1/10

US Classification:

381380

Abstract:

An earphone comprising an earphone housing having a body portion acoustically coupled to a tube portion extending from the body portion, the body portion having an acoustic output opening to output sound from a driver positioned therein into an ear canal of a wearer. An acoustic tuning member is positioned within the body portion for acoustically coupling the driver to the tube portion. The acoustic tuning member defines a back volume chamber of the driver and includes an acoustic output port for outputting sound from the back volume chamber of the driver to the tube portion to improve an acoustic performance of the earphone.

International Classification:

H04R 1/10

US Classification:

381380

Abstract:

An earphone having an earphone housing including a tip portion dimensioned to be inserted into an ear canal of a wearer, a body portion extending outward from the tip portion, and a tube portion extending from the body portion. The body portion has a face portion that faces a pinna region of the ear when the tip portion is inserted into the ear canal. A primary output opening, that outputs sound from a driver in the housing to the ear canal, is formed in the tip portion. A secondary output opening, that outputs air from the ear canal to the surrounding environment, is formed in the face portion. The primary output opening and the secondary output opening are horizontally aligned when the tube portion is positioned vertically downward and an angle formed between the primary output opening, the tube portion and the secondary output opening is less than 90 degrees.

International Classification:

D04H 13/00
D04H 1/00

Abstract:

Embodiments described herein may take the form of a textile product having one or more regions of reduced density. These reduced density volumes may form one or more features in the product. For example, the reduced density volumes may have better acoustic transmission properties, optical transmission properties, flexibility, and the like. Sound transmission may be enhanced not only in terms of clarity, but also overall range. That is, certain audio frequencies that the textile may normally block when in an unaltered state may pass through a textile having reduced density or reduced density regions.
