Description

TITLE: EARPHONE

DESCRIPTION

The present invention relates to earphone apparatus (e.g. apparatus comprising at least one earphone), and particularly but not exclusively to earphone apparatus provided in the form of headphones.

Earphones (e.g. circumaural or supra-aural earphones of the type connected together by a headband to form headphones or in-ear/in-the-canal earphones configured to be placed at the entrance to or in the auditory canal of a user's ear) are well known in the art. Active earphone apparatus often feature in addition to a simple power on/off switch control inputs used to switch between different operating modes (such as enabling or disabling active noise reduction), adjust an operating parameter (such as an equaliser setting or volume control) or control other devices to which they are connected (e.g. to provide play/pause control, fast-forward control, track selection and the like).

Controls may be actuated by the wearer through operation of a mechanical switch on the body of the earphones or through electronic equivalents of a mechanical switch (hereinafter "sensor switch") in the form of a touch sensor switch (e.g. capacitive touch sensor switch) or a proximity detector switch. The provision of such sensor switches (and control electronics associated with them) allows the deployment of "gestural" control strategies, in which the wearer signals herihis intention through a moving gesture of the hand or finger on or near the switches. The gesture is recognised by electronics in the earphones and the appropriate control command is issued.

The present applicant has identified the need for an improved design for earphone apparatus comprising a sensor switch.

In accordance with a first aspect of the present invention, there is provided earphone apparatus comprising: an electro-acoustic driver; a housing for receiving the electro-acoustic driver, the housing defining a rear volume for receiving rearwardly radiated sound from the electro-acoustic driver;; and a sensor plate mounted on the housing for receiving an input from a user; wherein the rear volume is fully or partially capped by the sensor plate.

For example, in embodiment the earphone apparatus may comprising: an electroacoustic driver; a housing for receiving the electro-acoustic driver, the housing defining a rear chamber for receiving rearwardly radiated sound from the electro-acoustic driver; an elongate passageway (or "acoustic waveguide") extending from an opening in a wall of the rear chamber to an outlet on an outer surface of the housing (e.g. an exterior surface of the earphone); and a sensor plate mounted on the housing for receiving an input from a user; wherein the elongate passageway is formed by a channel in the outer surface of the housing and capped by the sensor plate.

In this way, vented earphone apparatus is provided in which an inner surface of the sensor plate forms one surface of an acoustic cavity. In the case of earphone apparatus including an elongate passageway configured to provide an improved frequency response, the inner surface of the sensor plate may form one surface of the elongate passageway (e.g. sealing the elongate passageway along its length). Advantageously, the solution of the present invention allows for a potential reduction in the complexity of tooling/reduction in the number of components by virtue of the dual role of the sensor plate.

In one embodiment, the sensor plate is a touch sensor plate or proximity detector sensor plate.

In one embodiment, the sensor plate is a capacitive sensor plate (e.g. capacitive touch sensor plate).

In one embodiment, the sensor plate includes a conductive layer (e g. a metallic layer). In one embodiment, the conductive layer forms an outermost layer of the sensor plate. The outermost layer of the sensor plate may form a part of the exterior surface of the earphone (e.g. 30 may provide part of the outer cosmetic finish of the earphone).

In one embodiment, the housing is formed from a plastics material.

In one embodiment, the elongate passageway extends substantially perpendicular to a drive axis of the electro-acoustic driver.

In one embodiment, the opening substantially faces the rear of electro-acoustic driver (e.g. is aligned with a part of the rear of the electro-acoustic driver).

In one embodiment, the sensor plate is provided in a recess provided in the housing. In one embodiment, the recess is configured to define a gap (e.g. peripheral gap extending fully or 5 substantially around the sensor plate) between the sensor plate and outermost surface of the housing. In one embodiment, the outlet is provided in the peripheral gap.

In one embodiment, the elongate passage extends relative to a drive axis of the electroacoustic driver from a radially inner point to a radially outer point.

In one embodiment, the casing defines a vertical casing axis (e.g. axis orientated vertically when the earphone apparatus is mounted on or in a user's ear when their head is in an upright position) and a horizontal casing axis (e.g. axis orientated horizontally when the earphone apparatus is mounted on or in a user's ear when their head is in an upright position). In one embodiment, the elongate passage extends at an angle to the vertical and horizontal axes. In one embodiment, the inlet is located rearwardly of the outlet relative to the vertical axis.

In one embodiment, the elongate passage defines a substantially linear path extending between the inlet and the outlet. In one embodiment, the substantially linear path extends substantially between the inlet and the outlet.

In accordance with a second aspect of the present invention, there is provided a pair of headphones (e.g. circumaural or supra-aural headphones) comprising earphone apparatus in 20 accordance with the first aspect of the present invention.

An embodiment of the present invention will now be described by way of example with reference to the accompanying drawings in which: Figure 1 is a schematic front view of headphone apparatus comprising a pair of earphones in accordance with an embodiment of the present invention; Figure 2 is a schematic side view of the headphone apparatus of Figure 1 depicting line "S-S"; and Figure 3 is a schematic cross-sectional view through one of the earphones of the headphone apparatus of Figure 1 along line "S-S".

Figure 1 shows ANR headphone apparatus 10 comprising a pair of circumaural 30 earphones 20 connected by an adjustable headband 30.

As illustrated in Figures 2-3, each circumaural earphone 20 comprises: an electroacoustic driver 40; a housing 50 formed from plastics material for receiving electro-acoustic driver 40; a brushed aluminium sensor plate 60 glued to housing 50 and forming part of a capacitive touch sensor (electronics not shown); and a circumaural ear pad 70.

Housing 50 defines a front volume 52 for receiving forwardly radiated sound from driver 40, a rear chamber 54 for receiving rearwardly radiated sound from driver 40, and an elongate linear passageway 56 extending substantially perpendicular to drive axis "A" of driver 40 from an inlet 56A in a wall 54A of rear chamber 54 facing a rear part 42 of driver 40 to an outlet 56B on an outer surface 50A of housing 50 forming an exterior surface of the earphone.

In accordance with the present invention, elongate passageway 56 is formed by a channel 58 in outer surface 50A of housing 50 and capped by sensor plate 60 received in a recess 50B formed housing 50. Recess 50B defines a gap 50C between sensor plate 60 and an outermost surface 50D of housing 50 extending around the periphery of sensor plate 60. As shown, outlet 56B is provided in the peripheral gap (with inlet 56A located rearwardly of outlet 56B relative to the vertical axis of the housing).
