Reduced Friction Eartips, And Systems And Methods Therefore

FIELD OF THE APPLICATION

The present application relates to eartips and earplugs with reduced friction, and more particularly, though not exclusively, eartips that have been lubricant treated or coated.

BACKGROUND

Many devices have been developed over time to deliver acoustic content to a user. Many of these devices take the form of an earphone (a device to deliver audio content directly to the ear, e.g., muff, earbud, in-ear system, hearing aid), which can be connected either wired or wireless to a computational device which delivers content or standalone (e.g., hearing aid). Most designs of earphones have electrical components that are uniquely oriented for a particular form factor and not easily transferrable to other form factors. In essence the electronics are often forced into a form factor rather than a smallest electrical package developed and the form factor developed around the package. Additionally, when the earphone has a component that is at least partially inserted into the ear canal, comfort can be an issue in prolonged use. Besides the pressure exerted against the ear canal wall, the ease of insertion can have an impact on perceived comfort.

Also, hearing protection can take several forms such as earplugs and muffs. Such hearing protection devices attenuate acoustic energy before it reaches the eardrum (tympanum) by creating an insertion loss that is achieved by reflection of the sound waves, dissipation with the device's structure, impedance of the waves through tortuous paths, closing of acoustical valves, and other means. For a hearing protector, the amount of sound pressure level (SPL) reduced, usually measured in decibels (dB), is typically depicted graphically as a function of frequency. Comfort can additionally be an issue for earplugs, as can the eases of insertion.

Many eartips/earplugs are made from soft elastomers and polymers of low durometer for comfort, however soft materials have large coefficient of friction which can cause discomfort during insertion and removal.

SUMMARY

Devices, system and methods for saturation, coating and preparing eartips is disclosed.

In general eartips are composed of a contact outer portion and a stent portion. The outer portion of an eartip (e.g. outer bulb surface) contacts the ear canal wall when inserted into the ear canal. The inner portion contains a core or channel that can fit on a stent (earphone eartip), while a wider potion aids in insertion onto a stent, or if used as an earplug the core or channel will be at least partially filled in or blocked. Prior to insertion into an ear canal the outer portion and inner portion encapsulate or receive a structure (eartip membrane contacts a structure (e.g., stent part, ledge-movable or part of stent), when inserted or as presented (final form after folded from a negative mold)) a medium (e.g., gas, fluid) that can have an opening aiding molding. Note that the opening can be faced inward toward the ear canal or formed to face toward the ambient environment. Note that the eartip and stent can be fabricated from various materials (e.g., silicon, urethane, rubber) and can include internal channel (tubes). The stent can also be a multi-lumen (i.e., multi-passageway) stent where the channels/tubes are various lumens of the multi-lumen stent, or solid (e.g., earplug stent). Note that the material of the membrane can have different properties from the stent or membrane wall or channel wall. Upon insertion into an ear canal, the ear canal wall pressure on the outer portion of a ridge and the outer portion can move radially and axially to relieve the pressure pressing against the ear canal wall. This is in contrast to foam tips that will always press back radially dependent upon the amount of deformation of the foam. The combination of radial and axial movement of the outer section helps decrease pressure on the ear canal wall and increase contact area also decreasing pressure for a given retaining force.

In one embodiment, an eartip can have an outer portion, an inner portion, and an encapsulated volume formed by the inner and outer portion, wherein the outer portion is designed to contact the ear canal, and wherein the inner portion is designed to fit upon a stent. The eartip can also have a passage to an ambient environment, where the passage is decreased when the eartip is inserted upon a stent or inserted into an ear canal. Also, the encapsulated volume may be at a pressure that is reduced when pressure on the outer surface exceeds a threshold value. Although a specific example of an eartip has been described, embodiments herein should not be interpreted to be limited to any type of eartip.

In another embodiment, an eartip may have an inverted body, where when the inverted body is at least partially folded on itself the inverted body is arranged to a bulbous region sized for insertion in an ear canal, a cavity internal to the bulbous region that holds a gas or enclosed volume, where increasing pressure on the bulbous region releases a portion of the gas. As such and as disclosed herein, gas can escape from enclosed volume or cavity in the eartip to customize the pressure or force provided by the eartip to provide a snug and comfortable tip without the eartip causing user discomfort from excessive pressure or force. Also, the eartip may have a channel wall that forms the cavity with the bulbous region and that forms a core through a stent can be inserted and/or received.

In one embodiment, the eartip can have a plurality of bulbous regions. Likewise, the eartip can have a plurality of cavities, where each cavity of the plurality of cavities is formed by each bulbous region of the plurality of bulbous regions and the channel wall. The eartip can also include a transition region between the plurality of bulbous regions where the transition region has a concavity that is inverse to the convex surface of the bulbous regions. The eartip can also have a lip extending from the channel wall and a sealing section extending from the bulbous region.

In one embodiment, a sealing tip can be located on the sealing section can be provided. In some arrangements, the cavity is sealed by seating the sealing tip against the channel wall. Also, the sealing tip can have a material property between 2 Shore A to 90 Shore A. Also, the eartip can be an earplug with a U.S. Environmental Protection Agency (EPA) Noise Reduction Rating (NRR) rating of at least 3.

Methods of manufacturing an eartip and/or earplug are also disclosed. One method can include printing an eartip as an inverted body, such that when the inverted body is at least partially folded on itself the inverted body is arranged to include one or more of the features disclosed herein. For instance, the eartip can have a bulbous region sized for insertion in an ear canal, a cavity internal to the bulbous region that holds a gas, where increasing pressure on the bulbous region releases a portion of the gas. Further, the method can provide an inverted body eartip with a material property between 2 Shore A to 90 Shore A.

In another embodiment, an earphone system is disclosed. The earphone system can include an earphone and an eartip. The eartip can have structures and functionality described herein and include a reduced skin friction (e.g., less than 2) eartip as a result of methods described by embodiments. The friction of human skin varies, as described in Reference 1 “Tribology of Skin:review and Analysis of Experimental results for the Friction Coefficient of Human Skin” by S. Derler and L. C. Gerhardt, Tribol Lett (2012) 45:1-27, incorporated herein by reference in its entirety. Reference 1 states that friction (e.g., with textiles) actually increases in skin due to water moisture (section 2.4.1, Reference 1), hence a hydrophobic treatment solution (e.g., mineral oil, waxes, olive oil, vegetable oil, teflon coating) should aid in repelling molecular bonding with water, decreasing friction.

In another embodiment, a method of forming an eartip is disclosed. The method can include forming a mold of an unfolded shape of an eartip, providing or supplying a flexible material to the mold for a threshold time and temperature for curing to form a cured inverted eartip, removing the cured inverted eartip and folding at least a portion of the cured inverted eartip to form a final eartip. Forming a mold can be skipped if a mold already has been made. Also, folding at least a portion of cured inverted eartip is optional.

In another embodiment, an earphone is disclosed. The earphone can include a housing, where the housing includes a stent configured to accept or insert into various foam tips, flange tips, and eartips. The earphone can also include an electronics package unit, where the electronics package unit includes an electronic package, and an electronic package housing, wherein the electronics package unit is designed to be independent of the housing. The earphone can also include a key, where the key is part of the housing and is designed to fit with the electronic package unit, where the electronic package includes two microphones and a speaker.

In certain embodiments, the outer portion of an eartip (e.g. the outer surface of an eartip) contacts the ear canal wall when inserted into the ear canal. The inner portion contains a core that can fit on a stent, while a wider portion (inside funnel shape of a ridge) aids in insertion onto a stent. Prior to insertion into an ear canal the outer portion and inner portion encapsulates a medium (e.g., gas, fluid) that can have an opening aiding molding. Upon insertion onto a stent the inner portion can move flexibly outward decreasing the opening, and/or upon inserting into an ear canal, the ear canal wall can press inward on the outer surface toward the stent moving the outer portion of the ridge inward, decreasing the opening. Note that the opening can be faced inward toward the ear canal or formed to face toward the ambient environment. Note that the stent can be fabricated from various materials (e.g., silicon, urethane, rubber) and can include internal channel (tubes). The stent can also be a multi-lumen (i.e., multi-passageway) stent where the channels/tubes are various lumens of the multi-lumen stent. Upon insertion into an ear canal the ear canal wall pressure on the outer portion of a ridge and the outer portion can move radially and axially to relieve the pressure pressing against the ear canal wall. This is in contrast to foam tips that will always press back radially dependent upon the amount of deformation of the foam. The combination of radial and axial movement of the outer section helps decrease pressure on the ear canal wall and increase contact area also decreasing pressure for a given retaining force.

Although the non-limiting examples herein discuss AirTips™ embodiments discussed herein can be applied to eartips and earplugs in general.

These and other features of the eartip, earplug, earphone systems and methods are described in the following detailed description, drawings, and appended claims.

DETAILED DESCRIPTION OF THE INVENTION

Eartip often are made of soft materials that also have high coefficients of friction (e.g., silicone, high coefficient of friction, greater than 3 (unitless) measured per ASTM standard D1894). A higher coefficient of friction causes the eartip to grab the skin and prevent the ear tip from deforming smoothly and conforming to the ear contour as it is inserted. A surface or eartip material treatment as described below improves the comfort of ear tips and the quality of their fit.

Exemplary embodiments of eartips and earphone devices, and systems and methods therefore are disclosed. The eartips are self-adjusting for the variable sizes of user anatomy. In use, the eartip can adjust radially and/or linearly for maximum comfort with a maintenance force that is less than an insertion force. The structural configuration of the eartip provides such adjustability while providing a flatter high frequency attenuation profile that maintains audio quality in comparison to traditional ear buds. Further, such adjustability is provided for with improved manufacturing techniques

Exemplary embodiments are directed to or can be operatively used on various passive eartips for hearing protection or electronic wired or wireless earpiece devices (e.g., hearing aids, ear monitors, headphones, ear terminal, behind the ear devices or other acoustic devices as known by one of ordinary skill, and equivalents). For example, the earpieces can have one or more transducers (e.g. ambient sound microphone (ASM), ear canal microphone (ECM), ear canal receiver (ECR/SPKR)) for monitoring/providing sound. In all of the examples illustrated and discussed herein, any specific values should be interpreted to be illustrative only and non-limiting. Thus, other examples of the exemplary embodiments could have different values.

FIG. 1 illustrates various parts that fit within an earphone housing 1070 of a hearbud housing device 1100 that form an earphone device 1000. The parts that fit within the earphone housing 1070 can include an ASM 1120, an ECM 1130, an EPH 1050, a flexible circuit 1091 of an EP 1090, the EP 1090 itself, a SPKR 1080, and a cap 1060.

FIG. 2 illustrates an additional exploded view of a hearbud housing device 1100 with various components labelled and which are configured to be housed within the hearbud housing device 1100. For example, in certain embodiments, the components of the earphone device 1000 can include the hearbud housing device 1100, an earphone housing 1070, a cap 1060, and an electronic package housing 1050, which houses the electronics package (EP) 1090 that can include a speaker (SPKR or ECR) 1080, ambient sound microphone (ASM) 1120, an ear canal microphone (ECM) 1130, and supporting electronics that may form a part of the EP 1090. Note that any microphone that can be used in an earphone can be used for the ASM 1120 and ECM 1130. Additionally, any speaker that can be used in earphones can be used for the SPKR 1080 in the earphone device 1000.

FIG. 3 illustrates an eartip 300 with a cross sectional segment 310 showing a portion of the membrane 330 separating the inside 320 from the outside 340. The discussions that follow with regards to FIGS. 4 to 9 describe various levels of treatment solution (e.g., lubricant penetration, antibacterial solution) or coatings that can occur. For example FIG. 4 illustrates membrane 330 before treatment 450 surrounded by treatment solution 420, 440, where the treatment 450 results in a modified membrane 430 with embedded/absorbed solution. Methods of treatment are discussed in more detail with regards to FIGS. 12 and 16 below. With regards to FIG. 4, the molded eartip 300, can be dipped into treatment solution encompassing both sides (420, 440) for a period of time (e.g., 3-120 mins) at a particular temperature (e.g., room temp+1 C to 200 C). Placing the molded eartip 300 into a heated treatment solution, expands the eartip material, making it more susceptible to intake (absorption) of whatever solution the eartip 300 is in. Upon removal, when the eartip 300 reaches room temperature, the treatment solution will seep gradually from the eartip 300 due to the difference in absorption saturation at different temperatures of the eartip material. If the treatment solution is a lubricant, then the eartip 300 will be self lubricating for a period of time (e.g., 3 days to 6 months). Note that the treatment solution can also be an antibacterial, that helps keep the eartip 300 clean. The treatment solution (e.g., treatment of the eartip 300 material not a patient) can vary depending upon need, for example a lubricant (e.g., mineral oil), an antibacterial, an anti-viral, even medicines or vitamins that can be absorbed through the skin of the ear canal to treat a patient. Note that if a device having the eartip 300 on it has a biometric sensor(s) that needs better connection to the skin, the eartips 300 can secrete a substance that improve biometric pickup between the eartip 300 and the skin (e.g., one that improves the transmission of pickup signals such as infrared or acoustic energy). Another method of embedding treatment solution in the eartip material is to mix a very small portion with the resin before curing. For example, 0.02% to 25% by weight. For example, a 4-5% by weight of mineral oil mixed with High Strength 2 (Alumilite™) results in a cured eartip that reduces both kinetic and static friction coefficients. Note that the mixing can occur at elevated temperatures (e.g., room temp+1 C to 200 C) or even at room temperature, then allowed to cure. Note that various methods of curing, e.g., two or three part resin mixing, UV curing and other methods can also be used. Treated membrane 430 has been penetrated throughout to various levels based upon depth from the membranes 430 surface.

FIG. 5 illustrates membrane 330 before treatment 550 surrounded by treatment solution 520, 540, where the treatment 550 results in a modified membrane 530 with embedded/absorbed solution. The solution penetrates membrane 330 to a depth to form penetrated layers 560 and 570. The thickness of layers 560 and 570 depend on the concentrations of solutions 520, 540, on either side of membrane 330, as well as temperatures of 520 and 540. For example if the solution concentration (e.g., % (by weight or volume) mineral oil in solution) is greater in solution 520 than 540 (o vice versa), then over a period of time (e.g., 1 min to 24 hours) the thickness of penetration layer 560 will be greater than penetration layer 570.

FIG. 6 illustrates membrane 330 before treatment 650 surrounded by treatment solution 620, 640, where the treatment 650 results in a coating(s) 620, 640 on membrane 330. The solution coats membrane 330 a thickness to form coating layers 660 and 670. The thickness of layers 660 and 670 depend on the concentrations of solutions 620, 640, on either side of membrane 330, as well as temperatures of 620 and 640. Note that in addition to the coating layers 660 and 670, the solution may also penetrate a depth into membrane 330. Another method of coating the eartips 300 is to use a semi-conductive eartip 300 material and dip the eartip 300 into a solution with an applied voltage on the eartip 300 to combine with the electrode (e.g., in this case the eartip membrane 330). For example, suppose we wish to coat a layer of antibacterial copper on the outer surface of the eartip 300. Then solution 640 could be a 1.0 M (molar concentration) CuSO4 in 1.0 M H2SO4, where the eartip 300 (made of semi conductive to conductive material, e.g., copper nanoparticles mixed with precured resin) acts as the cathode. Application of a voltage between the eartip 300 and an anode (e.g., of copper) coats a thin layer of copper (e.g., 670 for solution 640, if both solutions 620, 640 contain electrolyte then 660 and 670). Note that if the eartip 300 is conductive it can connect with an antenna in an earphone to improve reception so that the head of a user acts as a counterpoise.

FIGS. 7-9 illustrate various types of coatings, saturations, with the treatment solution on one side (e.g., 740, 840, 940) of membrane 330. In FIG. 7 treatment 750 results in penetration of the treatment solution 740 into a depth of membrane 330 by a thickness 760, dependent on temperature of 330 and/or 740, pressure of 740 (e.g., 1 to 5 atmospheres), and treatment solution concentration. Treatment 850 results in the treatment solution on side 840 and not side 820, being roughly homogeneous throughout the membrane 860, also referred to as full penetration of membrane 330 with treatment solution. Note that another way to get a homogenous distribution (not necessarily fully saturated) of treatment solution within the membrane is to combine the treatment solution with the epoxy/resin before curing by weight or volume % as discussed above. Treatment 950 results in a layer 960 deposited upon membrane 330 where the treatment solution is on side 940 compared to side 920.

FIG. 10 illustrates 1200 a view of a molded eartip 1020 prior to folding. Molding the eartip unfolded enables molding, then folding the tip region results in a nearly closed cavity which is very difficult to mold outright. FIG. 11 illustrates 1300 the molded eartip of FIG. 10 folded to form a final or insertion arrangement eartip 1020. The material of the eartip 1020 is often stable to high temperatures (e.g., greater than 100 C), therefore to treat the outside surface (outside after folding) the treatment solution can be pooled into the cavity 1410 prior to folding, then heated (e.g., from about 40 C to 200 C) for a predetermined time (e.g., 1 min to 2 hours). FIG. 12 illustrates 1400 a view of a molded eartip 1020 prior to folding, with the inner membrane surface treated 1410. The treated eartip is then cleaned and folded 1500 (FIG. 12) so that the outside surface with the coating or penetrated surface 1510. FIG. 13 illustrates 1500 the molded eartip 1020 of FIG. 12 folded to form a final or insertion arrangement eartip, with the treated portion 1510 of the membrane facing outward.

FIGS. 14-15 illustrates (1600,1700) a view of a molded eartip 1020 prior to folding, with the inner membrane surface (becomes the inner surface when folded) treated to a selected length (1610, 1710, 1830), for example by dipping the untreated eartip 1020 into a heated treatment solution 1820 (FIG. 16). FIG. 16 illustrates 1800 a method of treating an eartip 1020 by dipping the eartip 1020 to a depth to a line 1830 into treatment solution 1820 in container 1810. FIG. 17 is an image of an eartip being submerged in a treatment solution. FIG. 18 is an image of an eartip being filled with a treatment solution.

FIG. 19 illustrates a method of treating an eartip 1020, where vapor coating 1900 is coated via vapor deposition 1910 onto the eartip 1020 forming a coated eartip 2000. FIG. 20 illustrates 2000 an eartip 1020 treated by the method shown in FIG. 19. Note that the eartip can be a polymer or elastomer (e.g. silicone, polyurethane, and thermoplastic) that is cured as discussed above and as known by one of ordinary skill in eartip design and manufacturing. Also note that any type of treatment solution (e.g., mineral oil, antibacterial solution) can be used.

An alternative method to reduce the friction of material used for the eartip is to use a very smooth mold surface so that the silicone or soft material touching the surface of the mold has very small variations across its surface., for example cover the mold surfaces with a Teflon spray that bonds to the mold surface prior to molding. Then when the mold material is inserted into the mold, the Teflon coated side will smooth out the mold material decreasing the skin friction of that side of the eartip.

In certain embodiments, the earphone device 2415 may include any number of ambient sound microphones that may be configured to capture and/or measure ambient sounds and/or audio content occurring in an environment that the earphone device 2415 is present in and/or is proximate to. In certain embodiments, the ambient sound microphones may be placed at a location or locations on the earphone device 2415 that are conducive to capturing and measuring ambient sounds occurring in the environment. For example, the ambient sound microphones may be positioned in proximity to a distal end (e.g. the end of the earphone device 2415 that is not inserted into the first user's 2401 ear) of the earphone device 2415 such that the ambient sound microphones are in an optimal position to capture ambient or other sounds occurring in the environment. In certain embodiments, the earphone device 2415 may include any number of ear canal microphones, which may be configured to capture and/or measure sounds occurring in an ear canal of the first user 2401 or other user wearing the earphone device 2415. In certain embodiments, the ear canal microphones may be positioned in proximity to a proximal end (e.g. the end of the earphone device 2415 that is inserted into the first user's 2401 ear) of the earphone device 2415 such that sounds occurring in the ear canal of the first user 2401 may be captured more readily.

The earphone device 2415 may also include any number of transceivers, which may be configured transmit signals to and/or receive signals from any of the devices in the system 2400. In certain embodiments, a transceiver of the earphone device 2415 may facilitate wireless connections and/or transmissions between the earphone device 2415 and any device in the system 2400, such as, but not limited to, the first user device 2402, the second user device 2406, the third user device 2410, the fourth user device 2421, the fifth user device 2425, the earphone device 2430, the servers 2440, 2445, 2450, 2460, and the database 2455. The earphone device 2415 may also include any number of memories for storing content and/or instructions, processors that execute the instructions from the memories to perform the operations for the earphone device 2415, and/or any type integrated circuit for facilitating the operation of the earphone device 2415. In certain embodiments, the processors may comprise, hardware, software, or a combination of hardware and software. The earphone device 2415 may also include one or more ear canal receivers, which may be speakers for outputting sound into the ear canal of the first user 2401. The ear canal receivers may output sounds obtained via the ear canal microphones, ambient sound microphones, any of the devices in the system 2400, from a storage device of the earphone device 2415, or any combination thereof.

The ear canal receivers, ear canal microphones, transceivers, memories, processors, integrated circuits, and/or ear canal receivers may be affixed to an electronics package that includes a flexible electronics board. The earphone device 2415 may include an electronics packaging housing that may house the ambient sound microphones, ear canal microphones, ear canal receivers (i.e. speakers), electronics supporting the functionality of the microphones and/or receivers, transceivers for receiving and/or transmitting signals, power sources (e.g. batteries and the like), any circuitry facilitating the operation of the earphone device 2415, or any combination thereof. The electronics package including the flexible electronics board may be housed within the electronics packaging housing to form an electronics packaging unit. The earphone device 2415 may further include an earphone housing, which may include receptacles, openings, and/or keyed recesses for connecting the earphone housing to the electronics packaging housing and/or the electronics package. For example, nozzles of the electronics packaging housing may be inserted into one or more keyed recesses of the earphone housing so as to connect and secure the earphone housing to the electronics packaging housing. When the earphone housing is connected to the electronics packaging housing, the combination of the earphone housing and the electronics packaging housing may form the earphone device 2415. The earphone device 2415 may further include a cap for securing the electronics packaging housing, the earphone housing, and the electronics package together to form the earphone device 2415.

In certain embodiments, the earphone device 2415 may be configured to have any number of changeable tips, which may be utilized to facilitate the insertion of the earphone device 2415 into an ear aperture of an ear of the first user 2401, secure the earphone device 2415 within the ear canal of an ear of the first user 2401, and/or to isolate sound within the ear canal of the first user 2401. The tips may be foam tips, which may be affixed onto an end of the earphone housing of the earphone device 2415, such as onto a stent and/or attachment mechanism of the earphone housing. In certain embodiments, the tips may be any type of eartip as disclosed and described in the present disclosure. The eartips as disclosed in the present disclosure may be configured to facilitate distributed reduced contact force, sound isolation for sound in the ear canal of the first user 2401 (i.e. between the ambient environment and the ear canal environment within an ear of the first user 2401), mold into a variety of forms and/or positions, encapsulate volumes upon insertion into an ear aperture of the first user 2401, have a pressure adjusting design, facilitate notched stent retention (i.e. on a stent of the earphone housing), facilitate stent insertion into an ear canal of the first user 2401 via an ear aperture of the first user 2401, or any combination thereof In certain embodiments, the eartip may be designed to provide sound isolation capability that is at least as effective as conventional foam and/or flange tips. Notably, the eartips may be manufactured and configured to be made in any desired size specifications and/or materials, and may be tailored to each individual user, such as first user 2401. In contrast to conventional foam or flange tips, an eartip according to the present disclosure may be adjusted for size without having to substitute the eartip with another eartip, may have an EPA NRR rating of NRR=18, may have a unique flatter high frequency attenuation profile so as to maintain audio quality, may have ease of manufacturability, and may be designed to distribute contact force and minimize radial force against a user's ear canal walls when positioned in a user's ear canal. Additionally, an eartip according to the present disclosure may be made of a non-porous material that is not closed cell foam or open cell foam.

In certain embodiments, the eartip may be designed so that the earphone device's 2415 retention force on the ear canal walls of the first user 2401 may be distributed over a larger area than traditional foam or flange tips allow, thereby reducing the pressure on the ear canal walls of the first user 2401. Unlike foam tips, which primarily provide a restoring radial force that exerts pressure against the ear canal walls of a user, the eartip is designed to move both radially and axially, which allows for more give and redistribution of contact over a larger area, and, thus, decreases the retention pressure. As a result, this allows for increased comfort for the user and allows the user to utilize the eartip for an extended period of time when compared to traditional foam and/or flange tips. In certain embodiments, the eartip utilized with the earphone device 2415 may be configured to encapsulate a volume of gas and/or liquid. In either case (i.e. gas or liquid), the bulk of sound isolation provided by the eartip is achieved through the reflection of ambient sound waves so that the encapsulated volume can be low mass. In certain embodiments, portions of the eartip may encapsulate a volume with the ability to release volume when pressed upon without having to incorporate complicated valves. The encapsulated volume may be achieved by the ear canal wall pressing radially and/or axially against the outer surfaces of the eartip, which may force the outer portion of the eartip to seal with the inner portion of the eartip. In certain embodiments, the inner portion of the eartip may be small than the outer diameter of the stent of the earphone housing upon which the eartip is placed so that upon insertion of the eartip on the stent, the inner portion stretches outward to meet the outer surface of the eartip, which further facilitates the sealing of the ear canal of the first user 2401.

In certain embodiments, the stent of the eartip, over which the eartip is placed, may be designed to have a smaller diameter front end and a larger diameter middle section to promote retention of the eartip on the stent itself. In certain embodiments, a portion of the eartip may have an inner core diameter that is smaller than the stent outer diameter so that the eartip provides radial compression upon the stent so as to enhance sealing and to add friction to prevent axial slippage within the ear canal of the first user 2401. In certain embodiments, an increased mid-section inner core diameter of the eartip may be utilized (i.e. larger than the smaller inner core diameter of the eartip), which may be configured to line up with the mid-section outer diameter of the stent of the earphone housing of the earphone device 2415. This may provide axial stability for the earphone device 2415, while simultaneously preventing axial slippage from the ear canal of the first user 2401. In certain embodiments, the eartip may have an insertion end that has a funnel shape, which aids in inserting the eartip onto the stent of the earphone housing of the earphone device 2415.

In certain embodiments, the eartip has a configuration that applies minimal force against the first user's 2401 ear canal. Additionally, the eartip can seal the first user's 2401 ear canal by providing at least 15 dB of attenuation across frequency. To facilitate manufacturability, the eartip may be molded inverted, thereby allowing inexpensive mass production. Lips of the eartip may then be folded to contact ledges to for the eartip that may be utilized by the first user 2401. Sealing and comfort depend upon an accurate fit within the first user's 2401 ear canal, and, as a result, eartips according to the present disclosure may be manufactured in several single sizes, and, because of the unique design of the eartips, a single eartip may be adjusted to fit multiple sizes, which minimizes manufacturing costs, while allowing for more flexibility, versatility, and for a greater number of sizes for the eartip. Notably, any of the features of any of the eartips described in the present disclosure may be combined and/or interchanged with any other eartips described in the present disclosure. Furthermore, the shape, size, features and/or functionality of any of the components of the earphone device and/or hearbud housing device described in the present disclosure may be modified for each particular user for the shape and size of each user's ear aperture and/or ear canal, or a combination thereof.

Notably, in experiments conducted using the eartip, the experiments have shown that the eartip allows for similar levels of sound isolation when compared to conventional foam and/or flange tips. For example, experiments have shown that the eartips provided in the present disclosure provided an NRR of 18 with a generally flat high frequency profile. A flat attenuation profile maintains an ambient environment's frequency profile when level reduced by the attenuation, which can be useful in maintaining the quality of ambient speech and music (or other audio content) during the level reduction process.

In further embodiments, the eartip may be configured to have an open configuration prior to insertion onto a stent of the earphone housing and/or the earphone device 2415 itself. By having an open configuration, the eartip may be mass produced using conventional molding techniques and/or by utilizing 3D commercial printers. The open configuration of the eartip also facilitates molding, and can be 3D printed, where the open configuration allows for resin removal. For example, resin removal may be achieved by utilizing commercial 3D printers that allow the use of lower durometer materials, such as Stratasys machines and the like. In certain embodiments, since the eartip has an open configuration, which is then sealed, any additional pressure can force encapsulated gas out of the eartip relieving the feedback pressure so as to keep the comfort level for the first user 2401 relatively stable.

In addition to the first user 2401, the system 2400 may include a second user 2420, who may utilize a fourth user device 2421 to access data, content, and applications, or to perform a variety of other tasks and functions. Much like the first user 2401, the second user 2420 may be may be any type of user that may potentially desire to listen to audio content, such as from, but not limited to, a storage device of the fourth user device 2421, a telephone call that the second user 2420 is participating in, audio content occurring in an environment in proximity to the second user 2420, any other type of audio content, or a combination thereof.

The fifth user device 2425 may also include an interface 2428 that may enable the second user 2420 to interact with various applications executing on the fifth user device 2425 and to interact with the system 2400. In certain embodiments, the fifth user device 2425 may include any number of transducers, such as, but not limited to, microphones, speakers, any type of audio-based transducer, any type of transducer, or a combination thereof.

Thus, although specific arrangements have been illustrated and described herein, it should be appreciated that any arrangement calculated to achieve the same purpose may be substituted for the specific arrangement shown. This disclosure is intended to cover any and all adaptations or variations of various embodiments and arrangements of the invention. Combinations of the above arrangements, and other arrangements not specifically described herein, will be apparent to those of skill in the art upon reviewing the above description. Therefore, it is intended that the disclosure not be limited to the particular arrangement(s) disclosed as the best mode contemplated for carrying out this invention, but that the invention will include all embodiments and arrangements falling within the scope of the appended claims.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. The scope of the following claims is to be accorded the broadest interpretation so as to encompass all modifications, equivalent structures and functions of the relevant exemplary embodiments. For example, if words such as “orthogonal”, “perpendicular” are used, the intended meaning is “substantially orthogonal” and “substantially perpendicular” respectively. Additionally, although specific numbers may be quoted in the claims, it is intended that a number close to the one stated is also within the intended scope, i.e. any stated number (e.g., 20 mils) should be interpreted to be “about” the value of the stated number (e.g., about 20 mils).

Thus, the description of the invention is merely exemplary in nature and, thus, variations that do not depart from the gist of the invention are intended to be within the scope of the exemplary embodiments of the present invention. Such variations are not to be regarded as a departure from the spirit and scope of the present invention.

Note that the durometer of the eartips can vary between 2 Shore A to 90 Shore A. Typical dimensions of the thickness of the membrane ending in the sealing section and lip or back ridge can be between approximately 0.001 mm to approximately 2 or more mm. The length (along the long axis) of an eartip can be from approximately 4 mm to approximately 25 mm or more depending upon the final usage. The outer diameter of contact portions of the eartip, such as sealing section 90, can vary from approximately 3 mm to approximately 50 or more mm, typically approximately 8 mm to approximately 18 mm. Note also that the thickness of the membrane of the body can be varied along the longitudinal length. For example the portion anticipated to contact the ear canal can be thinner, while the end of the membrane near the tip can be thicker to maintain restoring pressure.

The outer portion of an Eartip (e.g. a ridge) contacts the ear canal wall when inserted into the ear canal. The inner portion contains a core that can fit on a stent (earphone eartip), while a wider potion aids in insertion onto a stent, or if used as an earplug the core will be filled in. Prior to insertion into an ear canal the outer portion and inner portion encapsulate (Eartip membrane contacts a structure (e.g., stent part, ledge-movable or part of stent), when inserted or as presented (final form after folded from a negative mold)) a medium (e.g., gas, fluid) that can have an opening aiding molding. Note that the opening can be faced inward toward the ear canal or formed to face toward the ambient environment. Note that the stent can be fabricated from various materials (e.g., silicon, urethane, rubber) and can include internal

Methods of Manufacturing

The Eartip (eartip) can be fabricated by various means, for example injection molding, then sealed with various filler mediums (e.g. gas, liquid, gel), and inserted upon a stent, for example the eartip can have an extension portion that slides over the stent.

For example specific materials may not be listed for achieving each of the targeted properties discussed, however one of ordinary skill would be able, without undo experimentation, to determine the materials needed given the enabling disclosure herein. For example Elastosil™ 30A, 70A, High Strength 1, 2, 3, Moldmaking Rubber (Alumilite™ products), flexible 3D printable material, silicon, urethane, natural and synthetic rubber, high strength rubber, chloroprene rubber, EVA rubber, quartz fiber, can be used; however, any material that can be used within the ear canal can be used for eartips and any material that can be used for earphones (silicon, urethane, rubber, plastic, Elastosil, metal, wood, and the like) can be used in the earphone housing and components thereof. As discussed herein, the eartips can be printed on three dimensional printers while provided the Shore A hardiness discussed herein. Various material can also be used for the EPH, for example tough resin (FormLabs) if printed and any other materials, as mentioned if molded. Typical durometer for the in ear portions can be from shore A of 5-50.

The eartips can be formed as an inverted shape mold as discussed herein. As an example, the inverted mold can be formed as a partial cylindrical sleeve with the shapes and arrangements disclosed herein. Such manufacturing provides great advantages of reduced cost without sacrificing performance of the eartips. As disclosed, the inverted shape mold allows the user to folder over portions of the eartip to use the eartip. Such eartips can provide the performance disclosed herein while being designed to be disposable.

The foregoing is provided for purposes of illustrating, explaining, and describing embodiments of this invention. Modifications and adaptations to these embodiments will be apparent to those skilled in the art and may be made without departing from the scope or spirit of this invention. Upon reviewing the aforementioned embodiments, it would be evident to an artisan with ordinary skill in the art that said embodiments can be modified, reduced, or enhanced without departing from the scope and spirit of the claims described below.
