The present invention relates to an earphone, and more specifically to an adapter for an earphone that secures the earphone within a cavity or pocket of the ear of a user.
Conventional earphones that fit in a cavity or pocket proximate an acoustic meatus of an external ear such that the earphone remains in the ear are known. Some earphones, such as those that are bundled with Apple's iPod® and other media devices, rest in the pocket formed between the tragus, the antitragus and the acoustic meatus of the ear. However, because ears differ greatly in size and shape among different users and the earphones do not attach to the ear, such conventional earphones may unintentionally detach from a user's ear or may become displaced within the cavity of the user's ear.
U.S. Pat. No. 8,111,861 discloses an earphone having a base with adjustable tragus arms for securing the earphone to the tragus and anti-tragus of the ear and for attaching to differently sized ears. The base of the earphone of U.S. Pat. No. 8,111,861 prevents lateral (i.e., side to side) movement or displacement of the earphone and also prevents movement or displacement of the earphone in a downward direction toward the lobule of the ear.
In order to provide even greater security against movement of the earphone in either the upwards or longitudinal direction away from the lobule and toward the antihelix of the ear, it would be desirable to provide an earphone or an adapter for an earphone which remains secured in place within the cavity of a user's ear, such that upward movement or displacement of the earphone is prevented, and which is configured to be used with differently sized ears.
One aspect of the present invention is directed to an earphone device configured to be removably secured within an ear of a user. The earphone device comprises a main body having a base wall and a longitudinal axis; a first projection extending outwardly away from the base wall generally perpendicular to the longitudinal axis, the first projection having a first open end distal from the base wall and a second open end proximal the base wall; and a second projection formed at a position spaced apart from the first projection and extending outwardly away from the base wall generally parallel to the longitudinal axis. The second projection has a first end distal from the base wall, a second end proximal the base wall, a tearshaped body tapering from the first end toward the second end, and an opening formed through the tearshaped body. The second end defines a single connection point with the base wall. In a use position, the first projection extends inwardly toward the internal cavity of the ear and the second projection deforms to conform to the antihelix of the ear, such that movement of the earphone device relative to the internal cavity of the ear is limited.
The following detailed description of the invention, will be better understood when read in conjunction with the appended drawings. For the purpose of illustrating the invention, there are shown in the drawings embodiments which are presently preferred. It should be understood, however, that the invention is not limited to the precise arrangements and instrumentalities shown.

With reference to
In one embodiment, the earphone to which the adapter 10 is connected or with which the adapter 10 is integrally formed, preferably includes all of the components described in Auria's U.S. Pat. No. 8,111,861, specifically a speaker housing for enclosing a speaker and electrical components, a wire housing for housing electrical wiring extending from the speaker housing and encased in a protective sheath, and a base mounted to the speaker housing. As described in Auria's U.S. Pat. 8,111,861, the base preferably includes a projection and/or one or more tragus lobes for holding the earphone within the cavity of the ear and preventing lateral movement of the earphone therein.
With particular reference to
In one embodiment, the rim 18 of the adapter 10 may be press or snap fit onto an outer periphery of an earphone, such as one of the earphones described in Auria's U.S. Pat. No. 8,111,861, such that the earphone is removably received within interior cavity 20 of the adapter 10 through the access opening 22, with the speaker cover being proximate to or in contact with the interior surface 12b of the base wall 12 (see
The adapter 10 further includes a first projection 24 extending generally perpendicularly from the base wall 12. More particularly, the first projection 24 extends outwardly away from the base wall 12 in a direction that is generally perpendicular to a longitudinal axis L of the adapter 10 (see
Preferably, at least a first side or portion 26 of the proximal end 24b of the first projection 24 is integrally formed (and more preferably co-molded) with the base wall 12 and at least a second side or portion 28 of the proximal end 24b of the first projection 24 is preferably integrally formed (and more preferably co-molded) with the sidewall 16. As such, at one end of the adapter 10, the base wall 12 and the sidewall 16 transition into the first projection 24. More particularly, at the point of transition between the base wall 12 and the first portion 26 of the proximal end 24b of the first projection 24, the first portion 26 of the first projection 24 is generally sloped or angled, as shown in
At a position spaced apart from the first projection 24, the adapter 10 preferably further includes a second projection 30 extending generally perpendicularly from the base wall 12. Preferably, the second projection 30 is formed at a position approximately about 90° to 180°, more preferably approximately 120° to 135°, and most preferably approximately 90° relative to the first projection 24. However, it will be understood by those skilled in the art that the first and second projections 24, 30 may be formed at any positions relative to each other.
The second projection 30 preferably extends outwardly away from the base wall 12 in a direction that is generally parallel to the longitudinal axis L of the adapter 10 and generally perpendicular to the direction of extension of the first projection 24 (see
More particularly, a width Wa of the distal first end 30a of the second projection 30 is larger than a width Wb of the proximal second end 30b, such that the second projection has a body that tapers from the first end 30a toward the second end 30b which is preferably connected to the base wall 12 (see
The body of the second projection 30 also preferably includes an opening or aperture 32 extending therethrough. In one embodiment, the aperture 32 has a circular cross-sectional shape. The opening 32 allows the second projection 30 to be easily deformed in a variety of configurations, directions and the like. More particularly, the second projection 30 may be longitudinally deformed by bringing the first and second ends 30a, 30b toward each other and closing the opening 32.
When the adapter 10 is positioned on an earphone (i.e., such that the speaker cover is proximate to or in contact with the interior surface 12b of the base wall 12) and the earphone and adapter 10 assembly is positioned within a user's ear, the anatomy of the ear preferably at least slightly holds or compresses the adapter 10 therebetween to more securely mount the earphone within the user's ear and prevent the earphone from unintentionally disconnecting from or becoming displaced in the ear cavity or ear canal. More particularly, when the adapter 10 is positioned within a user's ear, the first projection 24 extends inwardly toward and possibly into the internal cavity (i.e., ear canal) of the user's ear and helps to limit movement or displacement, and more particularly any lateral movement or displacement, of the earphone within the user's ear. The second projection 30 extends upwardly toward the upper ridge, and more particularly, the antihelix of the user's ear and is positioned between the upper ridge (i.e., the antihelix) and the antitragus of the user's ear. More preferably, the second projection 30 directly contacts the upper ridge of the user's ear and may be deformed or moved in any direction, and more preferably in either the left or right direction, so as to conform to the antihelix of the user's ear. Accordingly, the adapter 10 can be accommodated within ears of differing sizes and contours.
More particularly, the second projection 30 may pivot at least slightly in either the left or right direction perpendicular to the longitudinal axis L of the adapter 10. As such, the second projection 30 (and more particularly the distal first end 30a of the second projection 30) contacts the antihelix of the ear, thereby limiting movement or displacement, and more particularly any longitudinal movement or displacement, of the adapter 10 within the user's ear. Specifically, the second projection 30 limits any upward longitudinal movement of the adapter 10 relative to the user's ear canal.
In addition to limiting upward longitudinal movement of the adapter 10, the first and/or second projections 24, 30 limit lateral movement of the adapter 10 relative to the user's ear canal. More particularly, in the use position, the first and/or second projections 24, 30 limit movement of the adapter 10 in a direction that is horizontal (e.g., approximately 90°) relative to the user's ear canal. The limiting of any lateral movement occurs because a component of the force transmitted to the adapter 10 when it is compressed within the anatomy of a user's ear serves to push the adapter 10 at least slightly backward toward or even into the ear canal. As such, the first and second projections 24, 30 ensure that the adapter 10 remains secured within the user's ear canal until it is manually removed by the user.
The adapter 10 is preferably constructed of an elastomeric, pliant and/or resilient material, such as a polymer (e.g., plastic) or rubber material, to alleviate pressure on the anatomy of the ear and to ensure that the adapter 10 is flexible and deformable as necessary to be accommodated within ears of different sizes and contours. In a preferred embodiment, the adapter 10 is constructed of a rubber material having a Shore A hardness of approximately 25. However, it will be understood that the adapter 10 may be constructed of any resilient material, such as foam, and may be integrally formed with a base of an earphone.
It will also be appreciated by those skilled in the art that changes could be made to the embodiments described above without departing from the broad inventive concept thereof. Also, based on this disclosure, a person of ordinary skill in the art would further recognize that the relative proportions of the components illustrated could be varied without departing from the spirit and scope of the invention. It is understood, therefore, that this invention is not limited to the particular embodiments disclosed, but it is intended to cover modifications within the spirit and scope of the present invention as defined by the appended claims.
