This disclosure relates generally to waterproof electronic assemblies, such as earphones, earphone electronic controls, as well as waterproof connectors.
Portable headphone speakers for listening to sound, whether used alone, in combination with a microphone for use with a mobile communication device, e.g., a cell phone, or to amplify external sounds, as with a hearing aid, can have a variety of configurations. Small headphones that fit in the concha bowl of the ear and direct sound into the ear canal, such as earbuds and earmolds, are preferred by some users due to their smaller size and weight relative to larger headphones that fit over the concha and/or pinna of the ear. This “in ear” style of headphone is often desirable during exercise, such as running or biking, or other physical activity that may include sudden or forceful movements of the head. It is desirable to have an earpiece or earmold associated with the headphone that retains the headphone in the ear while moving, and is still comfortable to wear.
Furthermore, it is desirable to have earphones that are waterproof when using a mobile communication device during exercise. Athletes and others who train or exercise may expose the headphones to their own sweat, as well as outdoor elements such as rain and snow. Entry of liquids into non-waterproof earphones can partially or completely inhibit their operation. Earphones that can be utilized and controlled when connected to a mobile communication device, e.g., a phone or tablet, despite exposure to or submersion in water, are highly desirable.
Moreover, it is also desirable to have a waterproof connector that can be connected to an encasement or another connector by rotating only a portion of the connector to achieve a watertight connection. By rotating only a portion of the connector, a user does not need to rotate the entire connector and cable in order to create a waterproof seal, allowing one-handed attachment, as well as minimizing the possibility of creating loops and tangles in the cable itself.
This disclosure describes a connector assembly for providing a waterproof connection to a case for an electronic device at an aperture of the case and for providing an electrical connection to an electrical interface of the electronic device when the electronic device is installed in the case. The connector assembly includes a connector body, an electrical cable attached to the connector body, and an electrical conductor at least partially contained in the connector body. The electrical conductor is electrically connected to the electrical cable and electrically engages the electrical interface of the installed electronic device through the aperture of the case to convey at least one of data and power between the installed electronic device and the electrical cable when the connector assembly is removably connected to the case. The connector assembly also includes an outer sleeve surrounding at least a portion of the connector body where the outer sleeve is configured to freely rotate around the connector body when the connector assembly is being connected to the case and is further configured to removably connect the connector assembly to the case at the aperture. The outer sleeve includes a securing region on a first end of the outer sleeve to removably secure the connector assembly to the case when the outer sleeve is rotated around the connector body. The outer sleeve further includes an inner gasket positioned to seal an inner sealing interface of the outer sleeve with the connector body when the connector assembly is connected to the case. Finally, the outer sleeve also includes an outer gasket positioned to seal an outer sealing interface of the outer sleeve with the case when the connector assembly is connected to the case.

The summary of the technology described above is non-limiting and other features and advantages of the invention will be apparent from the following detailed description of the invention, and from the claims.
The present disclosure is directed to an apparatus for comfortably securing an earpiece in the concha of a user's ear, such that the earpiece is not easily shifted in position during use, especially during vigorous physical activity such as jogging or biking, in which the ear may be subjected to movement that may otherwise jostle the earpiece from the ear. It is desirable to have an earpiece or earmold associated with the headphone that is comfortable to wear, and can be used by users in a variety of differently shaped ears while remaining securely retained in the ear even when the ear experiences forceful movement.
The present disclosure is also directed to earphones that are waterproof and dustproof, or resistant to intrusion of liquids such as water and sweat. The earphones may be connected via a cable to a waterproof, dustproof multi-function input (MFI) that may include a microphone and buttons. The earphones may be connected to via a cable to a waterproof, dustproof audio connector that can form a waterproof seal when connected to a case that houses an electronic device or to an adapter that connects to such a case.
As used herein, the term “exterior side” refers to a portion of the earmold that faces outward, away from the ear, when mated with an earpiece and inserted into the concha bowl of a user's ear. Conversely, the term “interior side” refers to the portion of the earmold that faces inward, towards the ear, when mated with an earpiece and inserted into the concha bowl of the ear.
The term “about” as used herein in reference to quantitative measurements, refers to the indicated value plus or minus 10%.
The present disclosure is directed to an apparatus for more comfortably securing an earpiece in the concha of an ear, such that the earpiece is not easily shifted in position during use, especially during vigorous physical activity, such as jogging or biking, in which the ear may be subjected to movement that may otherwise jostle the earpiece from the ear. It is desirable to have an earpiece or earmold, associated with the headphone, that can be comfortably worn by users having a variety of outer ear shapes while remaining securely retained in the ear even when the ear experiences forceful movement.
At the bottom of the cavity 210 is a thinned region 212. The thinned region depicted in
The earmold also includes a sound channel output port 220 that is hollow and allows sound from the earpiece to be directed into the ear canal. When the earmold is inserted into the concha cavum, the sound channel at the anterior portion of the earmold points towards and is proximate the entrance of the ear canal, but does not enter the ear canal itself. In some embodiments, the sound channel may enter a portion of the ear canal. In some embodiments, the anerior portion of the earmold will press against the anterior concha cavum, the posterior portion of the earmold will press against the posterior concha cavum, and the inferior portion of the earmold will press against the inferior concha cavum of a user's ear to secure the earmold and provide a feeling of fullness within the concha cavum. In some embodiments, more force is exerted between the anterior concha cavum and the posterior concha cavum than is exerted downward against the inferior concha cavum.
The earmold of
In some embodiments of the present technology, the earmold does not have a fin or flange 236.
The earmold described above may be a molded cover made of an elastomeric material, or it may be overmolded directly on or to the surface of an earpiece.
Earphones that fit inside the concha cavum of an ear may include waterproof earphones that rest inside the concha cavum without additional support (e.g., earbuds), or may be attached to an additional support mechanism that aids in preventing slippage or movement of the earbuds within the concha cavum. Exemplary support mechanisms may include a headband that partially encircles the top, front, or rear of the head, or structures for individually securing each earphone to its respective ear, e.g. ear clips or in-ear tension/friction support mechanisms such as described above. Additional support mechanisms like these may be made of firm plastic or other polymer that flexes, and may incorporate cloth and elastic components. The support mechanisms may also include electronic components such as a multifunction input (described below), a microphone, and/or a BLUETOOTH transceiver.
An exemplary waterproof earphone 500 of the instant technology is depicted in the exploded perspective view of
Cable 530 extends through an aperture in strain relief cover 526 (not visible) and into rear member 520, extends through the tuning backing 535, and is electrically connected to the diaphragm assembly (for clarity,
In certain embodiments, the waterproof sound channel membrane 515 may be affixed to the sound funnel 512 with a cap.
In alternative embodiments of waterproof earphones, the earphone may include additional components such as compression arms, a compression wedge, and a crimp bead that aid in maintaining a waterproof seal where the cable enters the earphone housing.
Rear member 620 includes a strain relief cover 626 that houses cable 630, and includes one or more rear member vents 524a and 524b. The rear member vents 624a-b (624c not visible) are covered by a rear vent membrane 625 and membrane plate 628. Membrane plate 628 is configured to secure vent membrane 625 to the interior surface of the rear member 620 and seal it against intrusion by liquids and/or particles. Membrane plate may be secured using a waterproof adhesive and/or ultrasonic welding. In some embodiments, the membrane 625 and membrane plate 628 may be secured to the exterior of the rear member. Rear member 620 also includes protrusion 629 configured to interact with a notch and protrusion (not shown) on the perimeter edge of front member 610 and aid in preventing accidental separation of the front and rear members. It is appreciated by those of ordinary skill in the art that the secure vent membrane 625 may include a single piece to cover all of the rear member vents, or may include two or pieces each corresponding to one or more of the rear member vents. In some embodiments, an adhesive may be added to secure the front and rear members. In certain embodiments, the front and rear members may be configured to be press-fit together, with or without adhesive to aid in preventing the separation of the two members. Rear member 620 also includes a channel 622 where the seal 623 is positioned. In certain embodiments, the earbud 600 may also include a tuning backing (not shown), as described above.
The sound output characteristics of the earphone described herein are affected by several factors, including the surface area of the driver, the geometry of the driver within the earphone housing, the surface area of the front member vents (e.g. sound vent 616) and rear member vents (e.g. 624a-c), the acoustic and mechanical characteristics of the waterproof mesh covering the vents, the volume of the stem portion of the earphone (e.g. strain relief cover 626), and the geometry of the front member opening (e.g. sound funnel 612).
In some embodiments, the driver may be about 14.2 mm in diameter in order to produce a desired level of bass frequencies, while still maintaining an overall earphone size that is retained safely and comfortably in the ear. The driver in earphone 600 may also placed much closer to the front member 610 of the earphone housing, reducing the volume of air in front of the increasing the air volume of the earphone at the rear of the driver. In some embodiments, the volume of the cavity in front of driver 640 may be about 0.4 cm3, including the volume of the sound channel. In some embodiments, nozzle or sound channel 613 may have a truncated cone or funnel shape to aid in sound wave propagation out of the earbud and into a user's ear. In some embodiments of the sound channel, the opening of the sound channel is may be slanted to enlarge the surface area of the opening. In some embodiments, the surface area of the sound channel opening may be about 13 mm2 and the length of the sound channel may be about 6.6 mm.
Front member vent 616 may be used to attenuate decibel levels of a specific frequency range. For example, the front member vent may have a surface area of about 3.8 mm2 to attenuate mid-high frequencies, for example between about 2500 kHz and about 3500 kHz.
In some embodiments, the volume of the cavity behind driver 640 may be about 1 cm3, and may be shaped with a truncated cone or funnel-like shape to maximize back pressure amplification, with a widest point near the driver and narrowing some distance from the rear of the driver. In some embodiments, rear vents 624a-c may be sized differently to accentuate and attenuate different frequencies. For example, rear vent 624c may have a surface area of about 5 mm2, rear vent 624a may have a surface area of about 6 mm2, and rear vent 624b may have a surface area of about 6.5 mm2. The surface areas of vents 624a-c may be adjusted and varied, and more or fewer vents may be used in the earphones to achieve desired acoustic characteristics.
Additional volume may be added in the stem region of the earphones where the cable exits the earphone housing.
In some embodiments of earphones, a minimum response loss within about 35 dB (90-55) deviation across a frequency range of about 50 Hz to about 20 kHz can be achieved, as well as enhancement of frequencies between about 4 kHz to about 8 kHz, and a suppression of frequencies between about 2500 kHz to about 3500 kHz. For example, an earphone with such response loss parameters may be achieved using: a driver of about 14.2 mm2 diameter; a front member volume of about 0.4 cm3; a sound channel with a slanted opening with a surface area of about 13 mm2 and a length of about 6.6 mm; a front member vent with a surface area of about 3.8 mm2; a rear member with a funnel-like shape and a volume of about 1 cm3; three rear member vents with surface areas of about 5 mm2, about 6 mm2, and about 6.5 mm2; and no volume in the stem portion.
Cable 630 is excluded from
The width or thickness of rib 683 (the distance between the exterior side and interior side of the earmold) may also change across a given rib's length. For example, the width of rib 683 near posterior portion 681 may be less than (or greater than) the rib's width near the body of the earmold, changing the compliance of posterior region 681. In some embodiments, the width of the rib may vary in thickness between about 1.5 mm and about 2 mm.
Cavity 686 includes a securing cavity 687 and duct cavity 688. Earmold 680 may be attached to earbud 600 (see, e.g.,
A user may insert earphones having earmolds as described herein into his or her ear by inserting the sound channel portion so that it lies proximate the entrance of the user's ear canal, and adjusting the posterior region of the earmold within the user's concha cavum. In order to ensure that the earmold is secured, the earphone may be rotated in a backwards direction within the concha cavum (using the sound channel as a pivot) such that the posterior region of the earmold moves downward towards the earlobe and away from the tragus and ear canal. This compresses the compliant posterior region of the earmold against the posterior wall of the concha cavum. This is facilitated by the slanted angle of the rib (see, e.g., rib 683 in
In some embodiments of waterproof earphones disclosed herein, it may desirable to include a waterproof multi-function input (MFI) that includes buttons or other inputs for controlling functions of an electronic device (e.g., volume, power, play or pause, call pick-up), as well as a microphone input that allows sound input through the MFI into an attached electronic device. The MFI is in electrical communication with the electrical device. In some embodiments, the MFI may be attached inline to a cord or cable that conveys electrical audio or other signals from the electronic device to a waterproof earbud of this or other disclosures. In some embodiments, the MFI may be attached to or integrated in a frame that connects the earbuds and wrap around the top of a user's head or back of the user's neck. In certain embodiments, more than one multi-function input may be in electrical communication with the electronic device. For example, an earphone cord may include one MFI that has only a microphone, and a second MFI that is separated from the first MFI and includes volume buttons. Inputs included on an MFI may include one or more buttons (or other tactile or capacitive inputs) for volume increase and decrease, mute, play, pause, record, track skip forward and backward, fast forward, fast reverse, call control (pick up and/or hang up), and may include one or more microphones. In some embodiments the MFI may feature user inputs, such as buttons for controlling a wireless connection, such as BLUETOOTH or the like. The MFI may also include a wireless transceiver (e.g. BLUETOOTH).

In embodiments of the waterproof earphones described herein, it is also desirable to have a connector for plugging into the reciprocal connector of an electronic device encased in a waterproof case, and forming a waterproof seal between the connector and the waterproof encasement. While this can be securely accomplished with connection mechanism in which the connector assembly is rotated to establish a tight seal, rotating the entire connector and cable can be problematic, requiring using two hands and resulting in loops and tangles in the associated cable. The disclosed waterproof connector assembly can be rotated using only the fingers of one hand, allowing one-handed attachment, as well as minimizing the possibility of creating loops and tangles in the cable itself.
In certain embodiments of the waterproof earphones, the connector may be in data communication with a wireless transceiver (e.g. BLUETOOTH).
Bushing 920 also includes a threaded region 921, configured for threading into a threaded aperture in a waterproof case for an electronic device. Outer gasket 925 (e.g., an O-ring) surrounds the circumference of the bushing at the base of threaded region 921, and is positioned proximate an outer gasket seat 926. When bushing 920 is threaded into reciprocal threads of a waterproof case, outer gasket 925 is at least partially compressed against an outer sealing interface or outer gasket seat 926, forming a waterproof seal with the waterproof case. Outer gasket 925 also compresses against a sealing interface on the encasement. The encasement sealing interface may be proximate the exterior surface of the encasement or on the inner surface of a port or aperture of the encasement that receives the securing portion of the connector assembly. Inner gasket 908 is also partially compressed against an inner gasket seat or interior sealing interface (not visible in
In some embodiments, threaded region 921 may be replaced with another rotatable securing mechanism, such as a bayonet-style securing mechanism. For example, two or more bayonet arms may extend outward from the surface of bushing 920. The bayonet arms then fit into bayonet grooves positioned in the inner surface of a connection aperture in an encasement. The bayonet grooves receive the bayonet arms and allow rotation of the bushing to secure the connector assembly to the encasement. For example, each of the bayonet grooves may have a first portion that is substantially parallel to the central axis of the case aperture, and a second portion that turns to allow rotation and securing of the bushing and connector assembly to the case. In some embodiments, the aperture of the encasement may include two or more bayonet arms, and the securing region on the distal end of the connector may include reciprocal bayonet grooves on the outside surface of the securing region. In some embodiments, more than one securing mechanism may be used. For example, both threads and bayonet arms or both threads and bayonet grooves may be used together as part of a securing region.
The exterior surface of bushing 920 also includes one or more ridges 923 for providing frictional or otherwise grippable surfaces for a user's fingers, and facilitating rotation of the bushing when a user screws the waterproof connector assembly 900 into a threaded aperture. Ridges 923 may vary in number, thickness, and shape. For example, there may be 2, 3, 4, 5, 6, 7, 8 or more ridges. The ridges may be triangular, rectangular, pentagonal, hexagonal, or an irregular polygonal shape. The ridges may also be ovoid or circular. An alternative embodiment of ovoid ridges 923 is shown in
In some instances, a waterproof case for an electronic device may have a connection aperture that lacks threading configured for use with a waterproof connector assembly. In such instances, a threaded insert may be inserted into the aperture to allow a waterproof connector assembly to be threaded into the case and form a waterproof seal.
In some embodiments of the waterproof connector assembly, the central axis of the assembly may be offset from the cable, in order to facilitate rotation of the bushing with one hand.
In some embodiments, waterproof connector assembly may include a female connector or socket, instead of a male connector.
A threaded aperture in an encasement may include threads integral to the aperture, or a threaded adapter that is inserted into the aperture from either in the interior or exterior of the encasement.
In some embodiments of waterproof cases that utilize a threaded adapter for use with a waterproof connector assembly, it is desirable that the adapter does not rotate while the waterproof connector assembly is being screwed into the adapter. In such embodiments, the adapter may have a flange circumference shaped to prevent rotation.
It is desirable to combine an earmold, a waterproof earphone, waterproof MFI, and waterproof connector assembly into a combined waterproof earphone assembly or system.
Connector body 1204 holds a portion of male connector 1202. In some embodiments, the connector may be female. Inner sleeve 1210 is adhered to male connector 1202, and includes a flange or slide stop 1212. Outer sleeve 1220 is in contact with inner sleeve 1210 but can freely rotate. In some embodiments, the inner sleeve and outer sleeve may include one or more detent features. The detent features may include one or more protrusions on both the inner surface of the outer sleeve and the surface of the connector body. The protrusions provide some mechanical resistance against rotation of the outer sleeve, which can be overcome by a user exerting additional force on the outer sleeve, resulting in the protrusions moving past each other. In some embodiments, the detent features may include protrusions and reciprocal grooves.
Connector body 1204 includes a shoulder 1207 underneath outer sleeve 1220. The distance between shoulder 1207 and slide stop 1212 is greater than that of the portion of outer sleeve 1220 that lies between them, leaving a gap 1214. Thus, outer sleeve 1220 can both rotate around the circumference of the male connector 1202, as well as slide parallel to the central axis of male connector 1202, as shown by the double-headed arrow in
Connector body 1204 includes a groove or channel 1205 that contains an interior seal or interior gasket 1208. Channel 1205 and interior gasket 1208 circumscribe the outer surface of connector body 1204 and are configured such that interior gasket 1208 forms a seal with the inner surface of outer sleeve 1220, as well as with channel 1205 of connector body 1204. Interior gasket 1208 may be a separate unit or may be overmolded into channel 1205. The size and hardness of interior gasket 1208 may be adjusted to allow outer sleeve 1220 to rotate around inner sleeve 1210, while still providing a radial watertight seal between outer sleeve 1220 and connector body 1204. While channel 1205 has straight, non-perpendicular sides creating a wide opening at the top of the channel, in some embodiments, the sides of channel 1205 are perpendicular and configured to contact the sides of interior gasket 1208. This can prevent interior gasket 1208 from rolling out of channel 1205 when outer sleeve 1220 is slid back and forth along inner sleeve. In some embodiments, channel 1205 may have an opening that is slightly smaller than the width of the channel's interior. The gasket may be formed from an elastomeric material and pressed into channel 1205 so that it is maintained inside the channel but partially emerges from the channel to provide a seal against outer sleeve 1220. In some embodiments, the geometry of channel 1205 is shaped to match the curvature of gasket 1208 to maximize surface area contact with the gasket and minimize the possibility of water leakage between the channel and gasket.
Outer sleeve 1220 also includes a threaded region 1221 on its distal end that is used to partially or completely enter a case aperture having reciprocal threads. In some embodiments, the threaded region may be replaced with two or more bayonet arms that fit into reciprocal bayonet grooves on a case connection port, to allow removable attachment. Exterior gasket 1225 is positioned proximate threaded region 1221 to form a seal between outer sleeve 1220 and a case when the connector assembly is attached.
