Description:
FIELD OF THE INVENTION 
     The present invention pertains generally to earphones and more specifically to earphones that include an ear hook that assists in securing the earphone to a user&#39;s ear. 
     BACKGROUND 
     Traditional headphones are designed to be worn on or around a user&#39;s head and include left and right earcups (or earpads) connected to each other by a headband. The headband and earcups combine to secure the headphones to a user&#39;s head. Earphones, by way of contrast, do not include a headband or bulky ear cups or ear pads that press against a user&#39;s head. Instead, earphones include a small speaker that fits within a user&#39;s ear canal or rests inside the edge of a user&#39;s ear. 
     Some earphones include a partial loop (commonly referred to as an “ear hook”) that fits between a user&#39;s skull and outer ear and loops or hooks over the portion of the ear that is connected to the skull. Ear hooks can be used with both wired and wireless earphones and can provide improved wearing comfort while helping better secure the earphones to a user&#39;s ear. 
     While many different earphone and ear hook designs have been developed, new and improved designs are continuously being sought. 
     SUMMARY 
     Various embodiments of the invention pertain to an earphone that includes an ear hook that can provide improved wearing comfort and an improved user experience with the earphones. The ear hook can include a first end and a second end and a curved portion in between. A body of the ear hook can be made from a flexible material molded over a formable member and a plurality of wires. The formable member can extend within the ear hook from the first end along a portion of the ear hook length towards the second end and can enable the ear hook to be bent along a portion of its length while retaining its bent shape. The plurality of wires can also extend within the ear hook along its length from the first end to the second end exiting the ear hook at the second end. Some embodiments of earphones according to the invention can further include an attachment mechanism that secures an earbud to the ear hook in an efficient and attractive manner forming a water tight seal between the two components. 
     To better understand the nature and advantages of the present invention, reference should be made to the following description and the accompanying figures. It is to be understood, however, that each of the figures is provided for the purpose of illustration only and is not intended as a definition of the limits of the scope of the present invention.

     DETAILED DESCRIPTION 
     The present invention will now be described in detail with reference to certain embodiments thereof as illustrated in the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without some or all of these specific details. In other instances, well known details have not been described in detail in order not to unnecessarily obscure the present invention. 
     In order to better appreciate and understand the present invention, reference is first made to  FIG. 1 , which is a perspective view of a pair of wireless earphones  100  according to an embodiment of the invention. Wireless earphones  100  include left ear and right ear pieces  102 ,  104  coupled to each other by a flexible cable  106 . Each of the ear pieces  102 ,  104  includes an ear hook  110  and an earbud  120 . As used herein, the term “earbud” includes both in-ear earphones, sometimes referred to as canal phones, that are inserted in the ear canal itself such as earbud  120  as well as small earphones that fit within a user&#39;s outer ear facing the ear canal without being inserted into the ear canal. Each of the individual earbuds  120  depicted in  FIG. 1  is of the in-ear earphone type, but embodiments of the invention are not limited to such and can be used with any type of earbud as well as with hearing aids and other small listening devices that are designed to sit within a user&#39;s ear. 
     Each earbud  120  includes an earbud housing that includes a primary housing  122  and a speaker housing  124  that can be integrally formed together or separate housing components attached to each other. Each earbud also includes an earbud tip  126  that is configured to be inserted within a user&#39;s ear canal. A speaker, not shown in  FIG. 1 , can be positioned within the speaker housing  124  and aligned with an acoustic port (not shown) through the housing  124  that delivers sound from the speaker through an opening  128  of earbud tip  126  into a user&#39;s ear canal. 
     Cable  106  can include a plurality of wires (not shown in  FIG. 1 ) that transmit electrical signals between the left and right earbuds  120 . For example, in some embodiments a wireless receiver can be included in one of the ear pieces  102 ,  104  and configured to wirelessly receive an audio signal stream that can be played over earphones  100 . The audio stream can include audio signals for left and right audio channels with one of the channels being transmitted to the user through the earbud at which the wireless receiver is located and the other audio channel being transmitted to the other earbud via cable  106 . In some embodiments cable  106  can be sized to loop around the back of a user&#39;s neck so that one or both earpieces  102 ,  104  can be removed from a user&#39;s ear and hang from the user&#39;s neck as a matter of convenience. 
     Ear hook  110  can include a body made from an elastomeric or other flexible material that defines an outer shape of the ear hook and includes a curved or generally u-shaped form enabling the ear hook to be positioned or hooked over the portion of a user&#39;s ear that is connected to his or her skull. In this manner, each ear hook  110  can help secure the earbuds  120  to a user&#39;s ear. To further improve the comfort level and user experience of wireless earphones  100 , each ear hook  110  according to embodiments of the invention can be formable. That is, each ear hook  110  can include a portion that can be bent along its length to a desired shape and retain that shape to provide a better fit for individual users. 
       FIG. 2  is a simplified view of an ear hook  200  according to some embodiments that can be representative of ear hook  110  shown in  FIG. 1 . As shown, ear hook  200  includes a body  202  that can be made from flexible material, such as elastomeric or similar material, that is molded or otherwise formed over various inner components of the ear hook forming a unibody structure for the ear hook. In some embodiments, body  202  can be made from a thermoplastic elastomer (TPE) which is a combination of rubber and plastic. 
     Body  202  is shown in  FIG. 2  in transparent form with dotted lines so that the inner components of the ear hook can also be illustrated in the figure. Such inner components can include a cable  204  and a formable member  206 . Cable  204  can be representative of cable  106  and include a plurality of wires  205  surrounded by an insulating jacket. Cable  204  can be embedded within ear hook  200  along the entire length of the ear hook from a first end  210  at which the individual wires  205  can be electrically connected to an earbud to a second end  212  from which the cable exits at an angle generally parallel to the length of the ear hook at its second end. 
     Formable member  206  can extend from the first end  210  of the ear hook along a portion of the length of the ear hook. For example, in some embodiments formable member extends along approximately ½ to ¾ of the length of ear hook  210 , and in some embodiments formable member  206  can be between 2 to 6 inches in length. Formable member  206  provides structure to ear hook  210  and is bendable into different positions in which a portion of the ear hook will retain the general shape of the formable member. As would be understood by a person of ordinary skill in the art, the shape retention feature of the ear hook can be limited in some instances by the thickness and materials of components of and within the ear hook, such as body  202  and cable  204 . That is, while the ear hook can be bent a reasonable amount to better accommodate different ear sizes of various users, there will be a limit to the radius or angle of any such bends based on the materials and components used to form the ear hook. 
     In some embodiments, formable member  206  can be a formable wire, for example, a stainless steel wire of approximately 1 mm in diameter. Embodiments are not limited to any particular material or shape of formable member  206 , however, and in other embodiments materials other than stainless steel and components other than a bendable wire can be employed. 
     Formable member  206  can be attached to cable  204  by one or more strain relief fasteners  220  spaced apart along a portion of the length of the formable member. For example, in the embodiment shown in  FIG. 2 , three strain relief members  220  are spaced along the length of member  206  with one of the strain relief members positioned at an end point of formable member  206 . In some embodiments, the strain relief fasteners include a cutout  222  that faces the u-bend of the ear hook and enables the fasteners to flex inward to accommodate ear hook  200  being bent into various shapes to better conform the ear hook over a user&#39;s ear. Cutout  222  can be, for example, approximately half the diameter of each fastener. 
     Each strain relief fastener  220  can be made from a rigid material, such as polypropylene, and in some embodiments can be molded over cable  204  and formable member  206 . For example, reference is now made to  FIG. 3 , which is a cross-sectional view of a strain relief fastener  220  taken along lines A-A′ of  FIG. 2 . As shown in  FIG. 3 , formable member  206  can be located adjacent to cable  204  and in some embodiments can be positioned directly over the cable. Cable  204  can include multiple insulated wires  205  surrounded by an inner insulating jacket  230 , for example an extruded thermoplastic elastomer (TPE) jacket. The strain relief fastener  220  can be molded directly over formable member  206  and cable  204 , and the body  202  of ear hook  200  can then be molded over the assembly of the strain relief fastener, formable member and cable to provide a desired outer shape to the ear hook. 
     Reference is now made to  FIGS. 2, 4 and 5  where  FIG. 4  is a cross-sectional view of a portion of the ear hook shown in  FIG. 2  taken along lines B-B′ and  FIG. 5  is a cross-sectional view of flexible cable  204  extending out of the ear hook shown in  FIG. 2  taken along lines C-C′. As shown in  FIGS. 2 and 5 , the portion of cable  204  that exits the ear hook from second end  212  can include a protective outer cable jacket  232  formed over inner insulating jacket  230 . Outer jacket  232  can extend into a portion of ear hook  200  and can be, for example, formed from another layer of thermoplastic elastomer or similar material that provides added strength, environmental and insulation protection for wires  205 . An additional strain relief fastener  224  can be formed over cable  204  at the location at which outer jacket  232  ends as shown in  FIG. 4 . Similar to strain relief fasteners  220 , strain relief fastener  224  can also be made from a rigid material, such as polypropylene, and molded over cable  204 . And, since fastener  224  is near the end  212  of the ear hook which is beyond the portion of ear hook  200  that can be bent and retain the bent shape, in some embodiments fastener  224  does not include a cutout or similar feature that enables fasteners  220  to be bent with the ear hook. 
     Ear hook  200  can be part of an ear piece, such as one of the left-ear or right-ear earpieces  102 ,  104  discussed above with respect to  FIG. 1 , and thus can include an earbud coupled to the ear hook at first end  210 . In some embodiments an earbud can be attached to the ear hook by two attachment posts  226  (shown in  FIG. 2 ) that extend out of first end  210  and a clip (not shown in  FIG. 2 ). Further details on the attachment of an earbud to an ear hook according to embodiments of the invention are described below with respect to  FIGS. 6-9 . 
       FIG. 6  is a simplified exploded perspective view depicting components of an earbud  600  that can be attached to ear hook  200  in accordance with some embodiments of the invention.  FIG. 7  is a simplified perspective view of a portion of earbud  600  and ear hook  200  spaced apart from each other prior to being coupled together.  FIG. 8  is a simplified cross-sectional view of portions of the earbud and ear hook shown in  FIGS. 6 and 7  coupled together, and  FIG. 9  is a simplified enlarged view of portions of earbud  600  and ear hook  200  coupled together. In each of  FIGS. 6-9 , earbud  600  can be representative of earbuds  120  shown in  FIG. 1 . 
     As shown in  FIGS. 6-9 , earbud  600  includes an earbud housing that includes a primary housing  602  and a speaker housing  604  that extends away from the primary housing. In some embodiments primary housing  602  and speaker housing  604  can be integrally formed with each other and in other embodiments the two housings can be separate components connected to each other to form the earbud housing. Primary housing can include a cavity  606  into which a circuit board assembly  608  can be housed. Circuit board assembly  608  can include various electronic components and circuitry, including one or more integrated circuits, that control the operation of wireless earphones as would be known to those of skill in the art. Speaker housing  604  can include an acoustic port and a cavity (not shown) in which a speaker (also not shown) can be positioned within and aligned to emit sound through the acoustic port. In embodiments where earbud  600  is of the in-ear variety, the earbud can also include an earbud tip  612  that has an opening aligned with the acoustic port and can be made from a deformable material that allows the earbud tip to be inserted within a user&#39;s ear canal to form an acoustic seal within the ear canal. 
     Primary housing  602  can also include a lip  624  (most clearly shown in  FIG. 7 ) that protrudes from an end surface  625  to surround openings  720  and an opening  722 . Lip  624  can fit within a matching groove  612  formed at the first end  210  of the ear hook to facilitate alignment and connection between the two components. Openings  720  are sized and shaped to allow attachment posts  226  to be inserted into housing  602 . Opening  722  is aligned with a location at which cable  204  exits ear hook  200  and is sized and shaped to accept the cable into housing  602 . 
     When attachment posts  226  are fully inserted through openings  720 , a retention clip  610  can be slid over posts  226  to secure earbud  600  to ear hook  200  as shown in more detail in  FIGS. 8 and 9 . Retention clip  610  can be made from a metal or similar material and can include a pair of openings  620  that enable the retention clip to be slid over posts  226  and an additional opening  622  that enables cable  204  to pass through the retention clip. The retention clip can further include a spring portion  802  that engages an inner surface  804  of each attachment post  226  as shown in  FIG. 8 . Spring portion  802  imparts a force (F) against the retention clips  226  pulling first end  210  of ear hook  200  towards surface  625  of primary housing  602 . 
     Attachment posts  226  can include one or more anchors  902  that secure the posts to ear hook  200 . For example, as shown in  FIG. 9 , attachment posts  226  can include a groove around a base of each post that allows the elastomeric or similar material  202  from which the bulk of the ear hook is made to be molded within the anchor region securely anchoring posts  226  to the ear hook. Additionally, attachment posts  226  can further include a second groove  904  at a location of the post that protrudes from ear hook  200 . The second groove can house an o-ring  906  that, combined with lip  624  and the force imparted by retention clip  610  provides a strong water tight connection between ear hook  200  and housing  602 .

Additionally, spatially relative terms, such as “bottom or “top” and the like can be used to describe an element and/or feature&#39;s relationship to another element(s) and/or feature(s) as, for example, illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use and/or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as a “bottom” surface can then be oriented “above” other elements or features. The device can be otherwise oriented (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
