DETAILED DESCRIPTION

(20) Some embodiments of a human-ear-wearable apparatus may be described with reference to anatomical features of the human ear shown named in FIG. 1.

(21) Example Human-Ear-Wearable Apparatus (Physical Structure(s)) Example Exterior Configurations

(22) FIG. 2 is an exterior view of a proximate side (closest to the ear) of human-ear-wearable apparatus 200. In the illustrated embodiment, human-ear-wearable apparatus 200 includes a housing 202, which in the particular view of FIG. 2 includes a proximal-side cover 204. Apparatus 202 also includes a mounting system 206.

(23) Housing 202 contains system electronics, mechanical devices, audio components, speakers, transmitters, receivers, microphones, processor(s), code, power supplies, all shown in later figures. Housing 202 provides a framework for containing these devices in a compact device able to fit, fully or partially, within the Concha-cavity area of the ear.

(24) Proximal-side cover 204 serves as a retention cover, (i.e. a shell or cap) to the proximal-side of apparatus 200. Proximal-side cover 204 may be constructed of any suitable material that can withstand moisture, and remain comfortable near or against the skin of the ear. For instance, proximal-side cover 204 may be constructed of plastic, semi-rigid rubber, fiberglass, other suitable materials, or any combination thereof. In addition, fabric of any suitable color, texture, material, and shape can be made to fit over, or integrated as a surface of proximal-side cover 204.

(25) Proximal-side cover 204 may include openings 208 for expansion of elements associated with mounting system 206. Mounting system 206 is configured to secure housing 202 to a human ear (such as FIG. 1).

(26) In various embodiments, mounting system 206 includes an elastomeric bladder 210 configured to inflate into a customizable counterpart shape of areas of the Concha and Meatus of the human ear. As shown in FIG. 2, elastomeric bladder 210 is in a deflated configuration. Thus, bladder 210, is partially or fully retracted within housing 202.

(27) In some embodiments, mounting system 206 also includes a stalk 212 extending from housing 202. Stalk 212 is configured in a curved shape for general alignment with the Cymba area of the human ear when mounting system 206 is secured to the Concha area of the human ear. In one embodiment, stalk 212 may be constructed of an elastomeric material and include an inner wire or conduit 214. In other embodiments, stalk 212 may be constructed of other materials such as coaxial wire with a plastic or rubber sheathing, or a combination of the foregoing.

(28) Stalk 212 may include a microphone 216 disposed therein for receiving voice commands from a user wearing apparatus 200. One or more portions of stalk 212 are configured to rest against the skin of the ear in the Cymba area of the ear.

(29) FIG. 3 shows another view of apparatus 200 with elastomeric bladder 210 partially inflated.

(30) FIG. 4 is an exterior view of an opposite side of human-ear-wearable apparatus 200 than shown in FIGS. 2 and 3. That is, FIG. 4 shows a distal side (away from the ear). Distal side of apparatus 200 is generally planar with proximal side of apparatus 200. External skins or custom exterior shells, of any color, texture and shape may configured to fit over the outside of the distal-side of apparatus 200. Thus a user can customize the look of the device.

(31) In the illustrated embodiment of FIG. 4, apparatus 200 includes a pump 402, coupled either directly or indirectly, to housing 202. Pump 402 is configured to pass air through a passage (not shown in FIG. 4) inside housing 202 to elastomeric bladder 210 (FIG. 2), when it central area 404 is depressed by the user. In one embodiment, pump 402 includes intake valves 406 for loading the pump with air. In one example, pump 402 may work with a duckbill intake valve (to be described). Thus central area 404 is generally resiliently flexible to allow movement of pump 402 back and forth. Inflation of bladder 210 (FIGS. 2 and 3), via the pump 402, is controllable by a user to form a customized fit of bladder 210 to the Concha and Meatus areas of the user's ear.

(32) FIG. 5 is a front side view of human-ear-wearable apparatus 200 showing partial views of both proximal and distal sides of the apparatus described with reference to FIGS. 2-4. As appreciated by those skilled in the art, after having the benefit of this disclosure, although housing 202 is generally shown as circular, housing 202 may be of other sizes, and shapes, such as elliptical, square, or other configurations.

(33) Example Mounting System

(34) FIG. 6 illustrates a proximal-side view of an example human-ear-wearable apparatus 200 with bladder 210 in a deflated configuration.

(35) In contrast, FIG. 7 illustrates a partial-cross-sectional view of the proximal side of human-ear-wearable apparatus 200 with bladder 210 in an inflated configuration.

(36) Referring to FIG. 7, in one embodiment, when air is pumped into bladder 210, the air pressure expands a finger-like projectile 704 longitudinally along a length of finger-like projectile 704 and laterally across a width of the finger-like projectile 704 thereby increasing the length and width of finger-like projectile 704 to an inflated configuration.

(37) That is, when inflated, elastomeric bladder 210 has outer walls 702, which form finger-like projectile 704 that extends through an opening 208 in proximal-side cover in response to air pumped into bladder 210 by pump 402 (FIG. 4).

(38) So when proximal-side cover 204 is positioned against a human ear (such as shown in FIG. 1), and bladder 210 inflates in response to air pumped into bladder 210. That is, bladder 210 unfurls and transitions from a deflated configuration (FIG. 6) to an inflated configuration (FIG. 7), and finger-like projectile 704 forms, and extends lengthwise into the auditory meatus of the human ear, and also expands diametrically (widthwise) toward the walls of the ear canal to apply an expansive force against the walls of the ear canal.

(39) In one embodiment, as elastomeric bladder 210 inflates, finger-like projectile 704 unfurls, i.e., unrolls out of itself, coaxially into the ear canal. This motion may reduce friction experienced by a user as the bladder material is stretched along the surface of the ear's skin.

(40) Referring to FIG. 7, in one embodiment, mounting system 206 also includes a second location 706 to the ear when bladder 210 is inflated. Specifically, an arc-shaped outer wall 708 extends through an opening 208 in cover 204, and expands radially in a generally opposite direction (i.e., approximately 120 degrees in the opposite direction) of finger-like projectile 704 when the bladder 210 is inflated with air. As appreciated by those skilled in the art after having the benefit of this disclosure, the exact angle offset between arc-shaped outer wall 708 and finger-like projectile 704 may be less than or more than 120 degrees.

(41) Arc-shaped outer wall 708 is configured to align with a posterior-auricular-sulcus area (see FIG. 1) of the human ear.

(42) So when proximal-side cover 204 is positioned against the human ear, and bladder 210 inflates in response to air pumped into the bladder from pump 402 (FIG. 4), bladder 210 transitions from a deflated configuration (FIG. 6) to an inflated configuration (FIG. 7). During this transition arc-shaped outer wall 708 (FIG. 7) expands to apply a force against a posterior-auricular-sulcus area (FIG. 1) of the human ear.

(43) Thus, elastomeric bladder 210 forms two counter opposing mounting mechanisms (finger-like projectile 704 and arc-shaped outer wall 708) to secure housing 202 to a human ear. A user operating pump 402 can configure an optimal-outer dimension of these walls for an optimal fit that is customized to his or her specific ear configuration.

(44) In some embodiments, when elastomeric bladder 210 is inflated, it may also expand beyond a surface of proximal-side cover 204 in openings 710 (FIG. 7) around the periphery of cover 204. This provides padding against the skin of the ear, passive radiators for enhancing bass response, and aids in enhancing the transmission of sound into the surface of the Pinna.

(45) In some embodiments, these portions of expanded bladder 210 at openings 710 vibrate at approximately 180 degrees out of phase with a woofer cone's (to be described) primary proximal side, and provide a richer and more immersive audio experience.

(46) After bladder 210 is inflated, mounting system 206 may be decoupled from a human ear by deflating elastomeric bladder 210. In one embodiment, a valve pressure release mechanism 602 (FIGS. 6 and 7) is configured to allow a user to control and selectively release pressure from bladder 210. Release valve 602 will be described in more detail below.

(47) FIG. 8 shows a transparent view of portions of the proximal side of apparatus 200. In one embodiment, a resilient member 802 disposed in bladder 210, and specially finger-like projectile 704, is configured help retract finger-like projectile 704 to a substantially decreased length (such as shown in FIG. 6) when bladder 210 is deflated, and/or transitions to a deflated configuration.

(48) In the illustrated embodiment of FIG. 8, resilient member 802 is a coiled wire. However, as appreciated by those skilled in the relevant art, after having the benefit of this disclosure, resilient member 802, may be other devices which provide a retraction force to cause bladder to retract, such as a spring, and a stretched length elastomeric cord. In addition, portions of bladder 210, and finger-like projectile 704 may be sheathed in a coiled thermoplastic material that exhibits a spring behavior for retracting finger-like projectile 704.

(49) In sum, aspects of the present disclosure include attachment mechanisms that feature several improvements over current attachment mechanisms for attaching human-ear-wearable apparatuses to the ear.

(50) Exemplary Speaker Mounted in Finger-Like Projectile

(51) As shown in FIG. 8, a speaker 804 may be mounted at a distal end of finger-like projectile 704 inside walls 702 of elastomeric bladder 210. In one embodiment, speaker 804 is a balanced armature driver. as appreciated by those skilled in the relevant art, after having the benefit of this disclosure speaker 804 may be other types of speaker devices. Resilient member 802 (i.e., in the illustrated embodiment is a recoiling wire) provides an electrical conduit to speaker 804.

(52) Exemplary Midplane and Internal Configurations

(53) FIG. 9 shows an exploded view of human-ear-wearable apparatus 200. Referring to FIG. 9, as shown as part of housing 202, human-ear-wearable apparatus 200 includes a midplane 902 with an outer ring 904 along the periphery.

(54) In various embodiments, midplane 902 is a planar central component of apparatus 200 that provides overall structure for apparatus 200. Midplane 902 may also provide a mounting mechanism for various internal components, such as speakers, electrical components, air relief and passage valves, electronic pass-through vias, microphones for receiving ambient sound, and electronic boards.

(55) Elastomeric bladder 210, is configured to connect to outer ring 904. Elastomeric bladder 210 is generally coplanar to midplane 902. When connected, elastomeric bladder 210 and midplane 902 are generally spaced apart to form an enclosed-sealed chamber (referred to as the first chamber) (denoted at brackets A-A) for maintaining compressed air therein.

(56) Diaphragm (or pump) 402 is coupled to outer ring 904 on an opposite side of the midplane 902 from elastomeric bladder 210. So midplane 902 is sandwiched between diaphragm 402 and elastomeric bladder 210. Diaphragm 402 is generally coplanar to the midplane 904. Diaphragm and the midplane are generally spaced apart to form a second chamber (denoted as bracket B-B) in FIG. 9.

(57) In some embodiments, midplane 902 includes one or more one-way valve(s) 906 extending through midplane 902 between second chamber (B-B) and the enclosed-sealed chamber (A-A). Each one or more one-way valve(s) 906 are configured to permit air to flow from second chamber (B-B) into the first chamber (A-A), when diaphragm 402 is compressed.

(58) Thus, midplane 902 may be capped on both sides (sandwiched between) elastomeric bladder 210 and diaphragm (pump) 402.

(59) Still referring to FIG. 9, in some embodiments, human-ear-wearable apparatus 200 also includes a relief valve 602 positioned in an aperture 908 extending through outer ring 904 configured to allow pressurized air trapped in the first chamber (A-A) to escape the first chamber (A-A).

(60) In some embodiments, electronic and audio components, such as one or more speakers 910 may be located in the first chamber (A-A). For instance, in the illustrated embodiment of FIG. 9, a speaker 910 (such as a headphone-sized cone driver (woofer)) may be directly or indirectly mounted to midplane 902. Speaker 910 may provide the main volume of sound emanating through bladder 210 to a user's ear.

(61) In one embodiment, apparatus 200 may include dual speakers (cone and balanced armature) positioned in bladder 210. Specifically, both a large diameter cone-type speaker 910 in the main volume of bladder 210, as well as a small, balanced armature type speaker 804 (FIG. 8) deep (distal end) in the meatus area (finger-like projectile) of bladder 210.

(62) A power source, such as Li-ion battery 912 may be directly or indirectly mounted to midplane 902. In one embodiment, battery 912 may be shaped to the interior shape of midplane 902.

(63) An electronic circuit board (not shown in FIG. 9) may also be mounted, directly or indirectly, to midplane 902, either in first chamber (A-A), in the second chamber (B-B), and or on both sides of midplane 906. The electronic circuit board (not shown in FIG. 9) may consist of an embedded computer system (CPU and associated integrated circuits, memory, persistent storage, ADC/DAC, voice command ASIC, Bluetooth, other wireless devices, and capability, various other sensor capabilities, and USB storage).

(64) Likewise, a processor including circuitry may be coupled to the midplane and/or collocated in the enclosed-sealed chamber.

(65) Various example features, and elements shown and illustrated in FIGS. 2-9 will now be described in more detail as follows:

(66) FIG. 10 is a perspective view of an example elastomeric bladder 210, which is ear-cavity shaped configured to inflate and fit completely in the Concha, Meatus, and Cymba areas of the human ear, thereby providing a secure and comfortable mounting anchor to hold apparatus 200 in the ear. In the illustrated embodiment, bladder 210 is partially covered by proximal-side cover 204. As appreciated by those skilled in the art after having the benefit of this disclosure, bladder 210 and proximal-side cover 204 may be a discrete elastomeric-bladder and retention cover. That is, cover 204 and bladder (or multiple bladders, which are location specific) 210 may be co-molded into a single cover component using two or more elastomers of approximately differing characteristics.

(67) To enhance the control over the inflation geometry of bladder 210, various shapes and types of fabrics 1002 may be adhesively affixed or molded into various locations within bladder 210. These fabrics can be of any suitable material, and may be woven or nonwoven in structure. These fabrics may also be electrically conductive and work in concert with an embedded sensor(s) 1004.

(68) For instance, in various embodiments, integral to the skin of the bladder, a plethora of electromagnetic sensors 1004 may be embedded or adhesively affixed, providing human body metrics, such as temperature, heart rate, and/or biometric security information, such as blood vessel patterning analysis and verification, inter-embedded sensor data such as ear-dimensional data based on electromagnetic values of other related sensors when in place in an authorized ear.

(69) Still referring to FIG. 10, in various embodiments, the meatus tip area 1006 of bladder 210 may be fabricated of a stiffer elastomeric, film, fabric, or plasticized paper-like material membrane, either continuous, woven, or non-woven in structure, to enhance sound transmission. While the balanced armature radiates sound through the center section of this bladder tip 1006, the surrounding region is designed to aid sound transmission from the larger cone driver through the compressed air volume of the bladder, and first chamber (A-A) (shown in FIG. 9).

(70) Integrated into bladder tip 1006 is the small balanced armature elastomeric retention cup 1008 for holding the driver deep within the meatus area of the ear. The speaker mounts into, and is suspended at a center axis of the bladder meatus tip 1006.

(71) In various embodiments, as the bladder shape changes into the Cymba section of stalk 212, it becomes a solid material (shown as 1010), which may be a stiffer elastomeric co-molded with bladder 210 itself. In one embodiment, a coaxial wire 214 in stalk 212 which is retained inside bladder 210, makes it's electrical connection in a coaxial connector molded inside stalk 212 (see i.e. FIGS. 2 and 6). The connector distributes its connections to either two or three externally accessible simple connectors formed in a socket facing the proximal side of the device. Into this socket is plugged a waterproof mems microphone 216 which makes contact to the wearer's skin within the Cymba area of the ear for command and communication audio input.

(72) FIG. 11 shows an exterior perspective view of diaphragm (pump) 402 (see also FIG. 4). FIG. 12 shows an interior perspective view of diaphragm (pump) 402. With reference to FIGS. 11 and 12, in some embodiments, diaphragm 402 uses an integrated bellows for inflating the bladder through midplane 902 (FIG. 9). For instance, in one embodiment, diaphragm 402 has integrated duckbill-style elastomeric intake valves 1202 for loading the pump with air.

(73) To close and seal the diaphragm and secure the intake valves to make the system waterproof, the face of the pump (FIG. 11) presses in to tightly seal to the diaphragm cover, and then the face overcenters (e.g. presses in such that it passes through a planar orientation to a concave orientation) to lock into place. This leaves the face in a slightly concave orientation, whereby it's outer edge is compressed against and secured to the inside rim of the diaphragm cover.

(74) FIG. 13 shows a perspective view of midplane 902. As shown, midplane is the primary structural element of the system, and provides the physical separation of the compressor (e.g. air compressor) (second chamber) (B-B) (FIG. 9) and compressed regions (e.g., bladder side) (first chamber) (A-A) FIG. 9) of the pneumatic system. For instance, referring to FIG. 12, in one embodiment, midplane 902 provides mechanical mounting purchase to the speaker 910, battery 912, wire mic stalk 212, and electronic components of the system.

(75) FIG. 14 shows another perspective view of example midplane 902. In this illustrated embodiment, midplane 902 vis--vis outer ring 904 provides the mechanical connection and sealing interfaces for the bladder and diaphragm components. An elastomeric compression valve 1402, and relief valve 602 is mounted to midplane 902.

(76) In one embodiment, relief valve 602 provides a mechanism for the controlled and selective relief of pressure from/in the bladder by precisely lifting the sealing edge of an elastomeric umbrella relief valve. Leverages the stem of the valve as the provider of spring pressure against the relief button, negating the need for an additional spring device.

(77) FIG. 15 shows an exploded view of various example parts associated with the relief valve system, including an umbrella relief valve 602, and a relief button 1404. Referring to FIG. 15, other elements associated with packaging for apparatus 200 include a gasket 1402 for encircling outer ring 904 of midplane 902.

(78) FIG. 16 shows a perspective view of an example midplane 902 with an example circuit board 1602 integrated on a distal side of midplane 902 according to one embodiment of the present disclosure. In another embodiment, circuit board 1602 may be mounted on either side of midplane 1602.

(79) In various embodiments, circuit board 1602 may include small embedded computer system, such as a CPU and associated integrated circuits, memory, persistent storage, ADC/DAC, voice control ASIC, Bluetooth and USB interconnection circuitry. In addition, expansion boards may be added with additional plug-in capabilities, including, but not limited to: programmable logic (FPGAs), wireless networking, cellular and other radio capabilities, additional persistent storage, graphic screencast capabilities, graphical projection capabilities, sensors for detecting hand/body gestures, hardware encryption, various other sensor capabilities, and other desired features as would be appreciated by those skilled in the art after having the benefit of this disclosure. Multiple expansion boards may be connected and used simultaneously, depending on functionality, available space, and system requirements.

(80) For example, in various embodiments, apparatus 200 includes an integrated circuit board 1602 a small embedded computer system, (CPU and associated integrated circuits, memory, persistent storage, ADC/DAC, power control, battery, wireless battery charging circuitry, voice control ASIC or FPGA installed IP, Bluetooth, USB interconnection circuitry, etc.), multiple speakers and microphones, designed for the purpose of being an in-ear wearable, extendable, modular human/machine interface using voice commands and audio feedback as the primary method of interaction and control.

(81) Additional control is accessible via a secure graphical and/or textual interface running on the device(s) and available via Bluetooth, USB, or any additional networking expansion functionality that may be present on the system, to be accessed and manipulated from another, external device using a graphical or textual interface screen (e.g. such as a client application running on a phone or a computer).

(82) The base computer system mainboard utilizes a modular interconnect system to allow additional interconnect-compatible boards to plug into and extend it, increasing the base compute systems' functionality. The devices (one per ear) can communicate between each other and to other local or remote systems, to negotiate and synchronize their activities, transfer and receive data, and/or leverage provided services, using either and/or both wired or wireless methodologies. Each device (left and right) may contain left and right versions of the same expansion board type where that configuration is appropriate, or employ completely different expansion boards to maximize total wearable-system functionality.

(83) Thus, in various embodiments, the human-ear-wearable apparatus 200 provides an extensible base platform upon which various audio-based input/output methodologies can be integrated in software, firmware, and hardware.

(84) FIG. 17 shows a posterior view of apparatus 200.

(85) FIG. 18 shows a proximal-side view of apparatus 200 with an example elastic-comfort sock 1802 attached thereto. In one embodiment, sock 1802 is configured to attach to a gasket (such as the gasket above) at a midplane meridian and has elastic cuffs to allow the sound producing and receiving areas to be free from coverage, but help to keep the sock in place.

(86) Sock 1802 may be washable and reusable and/or disposable elastic fabric sock that is stretched over and affixed to proximal side. Sock 1802 may be constructed of any suitable fabric such an elastic material similar to that of yoga pants, nylon, stockings, or ballet tights that can be provided in a variety of fuzz densities to allow the user's ear skin surface to breathe, equalize pressure around the bladder, and aid in audio feedback control.

(87) In one embodiment, sock 1802 is reversible, so one shape fits both left and right ear covers. In one embodiment, this sock also has an exterior component that covers over the Pina of the ear, wrapping around the entire ear as a cuff to terminate behind the ear where the ear attaches to the head, acting as an additional device retention system by helping to hold the device securely to Pinna of the ear.

(88) Apparatus 200 may use a wireless charger that uses an ear device-shaped receptacles equipped with sealed electrical coils for the charging of the device batteries, as well as an internal steam generating system that steam-cleans the elastomeric ear bladder between wearing. The system uses a mix of distilled water and isopropyl alcohol as the cleaning agent.

(89) In operation apparatus 200 may be used as a soundspace. Soundspaces are shared virtual sound rooms. Similar to a conference call, yet fully three dimensional in perceived acoustics. Individuals occupy a position in the space that all members are aware of, and this positional relationship awareness is shared amongst all members of the space. Soundspaces are programmable; shapes, sizes, acoustics, positional data (individual's locations within the room), movement withinthese can be exaggerated for effect, and are used like audio emoticons. In fact, you can completely speak through these personas, or themesin character if you will. You can whisper to someone in the room and only they can hear it. You can zoom into someone and it sonically appears as if the person is flying right up to your ear as they speak. You can be a member of any number of soundspaces at any given time.

(90) Any user of a soundspace can share with the room any input or output they are receiving or outputting, allowing all members to hear the ambient sound of a particular location, or any other sounds the user is actively experiencing. Uses for these soundspaces are many, but a small sampling might include:

(91) (a) Construction workers maintaining hands-free real-time communication (crane operator and high-rise steel workers).

(92) (b) First responders able to stay in constant hands-free communication in visually impaired environments (fire, smoke, etc.).

(93) (C) Remote learning and training situations.

(94) (D) Military squad communications.

(95) (E) TV reports, broadcastors, and anchors.

(96) These spaces may be either centrally managed (e.g. a shared server provides connectivity) which is optimal for widely dispersed participants, or fully distributed (e.g. only the members of the room are part of the communication) which is optimal when proximity allows and/or security dictates
