Assignee:

Apple Inc. - Cupertino CA

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:

H04R 1/10

Abstract:

A housing has a bud portion abutting an elongated stem portion. The bud portion is to fit within an ear. The bud portion has a primary sound outlet at its far end that is to be inserted into an outer ear canal, and abuts the stem portion at its near end. A speaker driver is inside the bud portion. Electronic circuitry inside the housing includes a wireless communications interface to receive audio content over-the-air and in response provides an audio signal to the speaker driver. A rechargeable battery as a power source for the electronic circuitry is located inside a cavity of the stem portion. Other embodiments are also described and claimed.

International Classification:

H04R 1/10
H04R 1/28

Abstract:

Intra-concha earphones are disclosed. In an embodiment, an intra-concha earphone includes a housing having a rear space divided into a back volume, a bass duct, and a vent chamber between a driver and a rear wall. The vent chamber may be acoustically coupled with the back volume through both an acoustic port and the bass duct. Furthermore, the vent chamber may be acoustically coupled with a surrounding environment through a vent port, which may be a sole acoustic opening in the rear wall. Thus, sound emitted by the driver may propagate through the acoustic port and the bass duct to meet in the vent chamber before being discharged through the vent port to the surrounding environment. Other embodiments are also described and claimed.

International Classification:

H04R 1/40
H04R 5/02

Abstract:

A multi-way speaker array is disclosed that includes rings of transducers of different types. The rings of transducers may encircle the cabinet of the speaker array such that the speaker array is rotationally symmetric. The distance between rings of transducers may be based on a logarithmic scale. By separating rings of transducers using logarithmic spacing, denser transducer spacing at short wavelengths is achieved while limiting the number of transducers needed for longer wavelengths by spacing them in larger and larger logarithmic increments. Transducers with overlapping frequency ranges may be used in the speaker array to avoid initial dips or shortfalls in directivity for corresponding beam patterns.

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.
