## Background
CROSS-REFERENCE TO RELATED APPLICATION
The present application is a continuation-in-part of co-pending, commonly owned, U.S. patent application Ser. No. 13/794,782 filed Mar. 11, 2013, entitled “METHODS AND APPARATUS FOR HEAD-WEARABLE PERSONAL SOUND SPEAKER SYSTEMS” the entirety of which is hereby incorporated herein by reference for all purposes.


FIELD
The present invention generally relates to personal sound speaker systems, and more particularly is directed to methods and apparatus for wearable personal sound speaker systems.
BACKGROUND
With the proliferation of cell phones and portable music devices, many personal portable sound speaker systems (e.g., headphones, earphones, etc.) have been developed that allow the user to participate in relatively vigorous activities (e.g., sports) while listening to their devices and largely block out other environment noises. In some environments however, personal sound systems that exclude or otherwise prevent a user from clearly hearing surrounding sounds can be undesirable. For example, while riding a bicycle or jogging on a street, there may be safety issues with not being able to hear traffic. In fact, many organized road race events do not permit competitors to wear any kind of device that is inserted into, covers, or contacts the competitor's ears. For example, the Official Rules and Regulations for the “Reach the Beach Relay” held annually in New Hampshire includes Rule No. 11.13 which specifies “the use of any type of earphone in the ear of the runner” is not permitted at any time during the race. Thus, what is needed is a personal sound system that allows users to enjoy music or communicate on a cell phone while not blocking out other environment sounds.

DETAILED DESCRIPTION
The present invention provides methods and apparatus for a wearable personal sound speaker system and kits for the same. In some embodiments, a visor or baseball style cap that includes a bill or sun shade that extends from the front of the visor includes one or more integrally formed flexible speaker elements within the bill. In other words, the speaker elements may be used to form the bill or part thereof. The bill and/or the speaker elements are disposed to direct sound that emanates from the speaker elements toward the ears of the user. In some embodiments, the speaker elements may be embodied as low-power (e.g, <0.1 W), thin (e.g., <0.2 inches), light weight (e.g., <0.1 g/cm2) flexible speakers, for example such as those manufactured by Verisonix Corporation of Taipei, Taiwan or the model TLF type speakers manufactured by Yamaha Corporation of Tokyo, Japan. In some embodiments, the speaker elements maybe directional speakers that emit sound in parallel, directed waves such that the sound is limited to the line in which it is aimed. In some embodiments, small conventional speakers may be used.
In alternative embodiments, the system can include arms or wings for mounting speakers or earbud sound systems to eyeglasses, sunglasses, a hat, a headband or other neck or head-worn clothing, item, or device without any part of the system contacting the user's ears or preventing the user from hearing sound from other sources but still allowing sound from the system to reach the user's ears with acceptable fidelity and volume.
Turning to FIG. 1, a side view of an example wearable personal sound speaker system 100 is shown. In the example embodiments shown, the wearable personal sound speaker system 100 includes a bill 102 with one or more integrally formed speaker elements 104.

The panels 920 permit access to the interior of the sound guides 904 to allow a manufacturer or user to more easily install speakers 912 within the sound guides 904. The sound guides 904 may include fasteners 922 (e.g., snap fit or friction fit couplings) that allow the speakers 912 to be held securely within the sound guides 904 and to be positioned to optimally aim sound into the sound guides and/or the user's ears. The sound guides 904 may be shaped to provide a passageway that amplifies and/or directs sound from the speakers 912 to the user's ears. The sound guides 904 may further include material to also aid in directing desired frequencies to the user's ears.
In some embodiments, the wings 910 may be permanently or removeably attached to the electronics compartment 916. The electronics compartment 916 may include a control panel 924 for controlling the electronics 914.
Turning now to FIGS. 12 to 21B, in some embodiments, the invention can include a wearable personal sound speaker system kit for mounting the speakers of an existing audio device onto head or neck worn items such as headbands, glasses, googles, hair clips, barrettes, hair bands, hair claws, hair pins, bobby pins, bandanas, head wraps, scarfs, turbans, hats, caps, visors, tiaras, crowns, laurel wreath, braces, headgear, helmets, faceguards, facemasks, neck braces, eye guards, masks, or other items. The speakers can be any type of relatively small, lightweight speakers such as headphone speakers, ear-bud speakers, earphone speakers, electrostatic speakers, etc.
Embodiments of the wearable personal sound speaker system kit can include two housings for the speakers that are adjustably connected to two attachment mechanisms (i.e., one housing connected to one attachment mechanism) for coupling the kit to the worn/wearable item (e.g., the brim of a cap, the frame of glasses, etc.). The housings can be funnel or cup shaped to direct sound toward the user's ears. The housings can include a speaker mounting system to releasably hold the speakers within the housings and to allow the speakers to be aimed at the user's ear canals. The speaker mounting system can include clips or clamps configured to friction fit to the speakers. An adapter or collar with a moldable pad that closely contours to the speaker can be provided that friction fits into the clips or clamps of the mounting system. Such a moldable pad allows many different size speakers to be securely held by the speaker mounting system. The housings can also include a channel for securing and routing wires connecting to the speakers. In some embodiments, the housings can be made from acrylonitrile butadiene styrene (ABS), polyethylene, polypropylene, polystyrene, or polyvinyl chloride plastic or any other lightweight practicable materials.
In some embodiments, the housings can each include a removable access panel. The access panel can provide an opening in the housing to make it easier to install the speakers in the housings. The access panels can be adapted to snap fit into openings in the housing. The access panels can include decorative features such as a product logo or other graphic images. Different color access panels can be provided with different decorative features to change the look of the kit to suit individuals' preferences. In some embodiments, the access panels can be disc shaped, oval shaped, or have other shapes. In some embodiments, the access panels can include three dimensional designs or textures such as grooves, patterns, logos, or other shapes.
The housing can be coupled to the attachment mechanism via a connector. The connector can be adjustable and adapted to allow the housing to be positioned relative to the ear of the user as desired. An adjustable connector allows the housing to be moved away from or toward the ear or anywhere in between, above or below the ear or anywhere in between, in front of or behind the ear or anywhere in between, and rotated parallel to or perpendicular to the ear or anywhere in between. The adjustable connector can include a flexure bearing which can be embodied, for example, as a rubber coated or encased bendable metal wire that holds its position after being bent. The flexure bearing allows the housing to be moved up, down, laterally and rotationally relative to the user's ear when the kit is mounted on a worn item. The adjustable connector can also include a slide bearing which allows the housing to be translated toward or away from the attachment mechanism. The slide bearing can be embodied as a carriage or member constrained to move in a channel. Any practicable slide bearing made of any practicable material can be used however. The slide bearing can include stops (e.g., detents) to define discrete positions of extension so users can find a position adjustment that works best for them and easily return to the same position later.
The attachment mechanism can be embodied as a clip or clamp that is releasably attachable to a portion of the worn item. For example, the attachment mechanism can be a clip that snuggly fits on a hat brim or eyeglass frame. In embodiments using a clip, the clip can include a gap suitable to snuggly fit the brim of a cap. The gap can include, for example, a studded, barbed, or rubber liner to further enhance the griping ability of the clip. In addition, the clip can include a spring bias to grasp the worn item. The clip can be embodied as a metal fold attached to a plastic frame of the attachment mechanism or the clip can be integrally formed from the frame of the attachment mechanism.
In some embodiments, the attachment mechanism can include an adjustment to more securely attach the mechanism to the worn item. For example, a threaded clamp that can be tightened can be used. The attachment mechanism can be embodied as numerous alternative fastening means including velcro®, hook and loop, buttons, snaps, pins, rivets, friction fit devices, clasps, hook and eye, buckle, toggle, frog, clinch, tie, drawstring, zipper, laces, magnet, twist-tie, etc.
In some embodiments, the components of the wearable personal sound speaker system kit (e.g., the housing, the adjustable connector, and the attachment mechanism) can be coupled together using snap fit fittings, epoxy, welding, or any other practicable fastening means. In alternative embodiments, the kit may only include the housing with an integrally formed attachment mechanism. For example, the attachment mechanism can be a clip extending from the housing that attaches to a hat hem or headband. In some embodiments, instead of attaching to a worn item, the wearable personal sound speaker system kit can attach to the user. For example, the housing can include an attachment mechanism that loops over the users ear or clips to the user's hair (e.g., a braid or lock of hair).
Turning now to FIG. 12, a perspective view of one side of an alternative wearable personal sound speaker system kit 1200 installed on the brim 1202 of a cap 1204 (shown in phantom) and worn by a user 1206 is depicted. A mirror image of the kit 1200 shown can be worn on the other side of the user's head. A speaker wire 1208 is visible leading down from the speaker housing 1210 to a sound signal source (not shown) such as an MP3 player, iPod®, smartphone, radio, etc. or to a device such as the BackBeat® GO 2 Bluetooth® Wireless Stereo Earbuds® manufactured by Plantronics Inc. of Santa Cruz, Calif. In the example embodiment shown in FIG. 12, the speaker housing 1210 is coupled to an attachment mechanism 1212 by an adjustable connector 1214. The example speaker housing 1210 shown includes an access panel 1216 that includes decorative grooves 1218.
FIG. 13 depicts a similar perspective view of as that of FIG. 12 but with the wearable personal sound speaker system kit 1200 adjusted to direct sound towards the ear 1302 canal of the user 1206. Note that the adjustable connector 1214 has been elongated so that the speaker housing 1210 can be shifted back to better align the speaker (not visible but see FIG. 14) with the user's ear canal. FIG. 14 depicts a magnified transparent “wireframe” view of the example kit 1200 embodiment of FIG. 12. This transparent view depicts the speaker 1402 installed in the housing 1210 and the routing of the speaker wire 1208 within the housing 1210.
FIGS. 15A and 15B are top views of the wearable personal sound speaker system kit 1200 of FIG. 12. Relative to FIG. 15A, FIG. 15B illustrates that the adjustable connector 1214 allows the installed speaker 1402 to be adjusted away from the user's ear 1302 so that sounds from the surrounding environment can easily reach the user's ear 1302 without being blocked by the kit 1200. Note that the adjustable connector 1214 in FIG. 15B has been both elongated and bent to achieve the desired position relative to the user's ear 1302.
FIGS. 16A and 16B provide inner side views of the example embodiment of the wearable personal sound speaker system kit 1200 of FIG. 12. In addition to depicting further details of the features of the example embodiment, the two drawings also illustrate the system's adjustability relative to each other. For example, FIG. 16A depicts the kit 1200 compacted while FIG. 16B depicts the kit 1200 extended.
As shown, embodiments of the speaker housing 1210 can include a speaker mounting system 1602 to releasably hold the speaker 1402 within the housing 1210 and to allow the speaker 1402 to be aimed at the user's ear canals. The speaker mounting system 1602 can include a clip or a clamp configured to friction fit to the speaker 1402. Other alternative arrangements and fasteners can be used for the speaker mounting system 1602. For example, flexible (e.g., rubber) fingers or nubs can be used to secure the speaker 1402 to the housing 1210. Note that the speaker 1402 can be rotated within the speaker mounting system 1602 such that sound emanating from the speaker 1402 can be directed to the user's ear canal.
Embodiments of the speaker housing 1210 can also include a speaker wire channel 1604 to releasably hold the speaker wire 1208 within the housing 1210. As shown, the speaker wire channel 1604 can be embodied as a cable guide formed by a ridge or wall within the housing 1210 and an exterior wall of the speaker housing 1210. The speaker wire channel 1604 can also provide support for securing the speaker 1402 in the housing 1210 and also serve as a strain relief on the speaker wire 1208 connection to the speaker 1402. For example, if the speaker wire 1208 snags on something and pulls, instead of yanking the wire 1208 from the speaker 1402, the wire channel 1604 can be adapted to retain the wire 1208 to prevent any damage being done to the connection to the speaker 1402.
Embodiments of the adjustable connector 1214 can include a flexure bearing 1606 and a slide bearing 1608. As discussed above, the adjustable connector 1214 allows the housing 1210 to be moved away from or toward the ear or anywhere in between, above or below the ear or anywhere in between, in front of or behind the ear or anywhere in between, and rotated parallel to or perpendicular to the ear or anywhere in between. The adjustable connector 1214 includes a flexure bearing 1606 which can be embodied, for example, as a rubber coated or encased bendable metal wire that holds its position after being bent. The flexure bearing 1606 allows the housing 1210 to be moved up, down, laterally and rotationally relative to the user's ear when the kit 1200 is mounted on the worn item. The adjustable connector 1214 can also include a slide bearing 1608 which allows the housing 1210 to be translated toward (e.g., as shown in FIG. 16A) or away from (e.g., as shown in FIG. 16B) the attachment mechanism 1212. The slide bearing 1608 can be embodied as a carriage constrained to move in a channel. Any practicable slide bearing 1608 made of any practicable material can be used however. The slide bearing 1608 can include stops (e.g., detents) to define discrete positions of extension so users can find a position adjustment that works best for them and easily return to the same position later.
FIG. 17 illustrates an exploded view of the wearable personal sound speaker system kit 1200 of FIG. 12. The access panel 1216 is shown separated from the speaker housing 1210 and the speaker mounting system 1602 can more clearly be seen without the speaker installed. Details of the features of the adjustable connector 1214 are also clearly depicted in the exploded view of FIG. 17. Other embodiments are possible. The example embodiment of the flexure bearing 1606 includes a foam rubber block 1702 and a bendable wire 1704. The example embodiment of the slide bearing 1608 includes a beam 1706 constrained to move in a channel 1708. Details of the features of the attachment mechanism 1212 are also clearly depicted in the exploded view of FIG. 17. Other embodiments are possible. The example embodiment of the attachment mechanism 1212 depicted in FIG. 17 includes an attachment frame 1710 adapted to couple to and support a metal fold clip 1712 having a spring bias.
Turning now to FIGS. 18A and 18B, a second embodiment of a wearable personal sound speaker system kit 1800 is illustrated. FIGS. 18A and 18B provide perspective views of the two sides (e.g., left side 1800A in FIG. 18A and right side 1800B in FIG. 18B) of a wearable personal sound speaker system kit 1800 according to some embodiments. Note that the two sides 1800A, 1800B are mirror images of each other. The example embodiment of the kit 1800 includes a speaker housing 1802 coupled to an attachment mechanism 1804 via an adjustable connector 1806. The speaker housing 1802 includes a speaker mounting system 1808 and a speaker wire channel 1810. Note that the speaker mounting system 1808 of this embodiment is adapted to accommodate speakers of different sizes by including multiple griping fingers as well as a compliant adapter that will be described in more detail below. The attachment mechanism 1804 includes and integrally formed clip member 1812 that extends from the attachment frame 1814. The adjustable connector 1806 includes a flexure bearing 1816 and a slide bearing 1818.
FIG. 19A is a diagram depicting an exploded view of the left side 1800A of the wearable personal sound speaker system kit 1800 of FIG. 18A. Some of the details of the example embodiment are more clearly represented in the exploded view. Specifically, the speaker mounting system 1808 includes at least three griping fingers that will accommodate at least two different size speakers 1402. In addition, a collar 1902 made of a flexible and conforming material on the inside (such as foam rubber) and a ridge shell on the outside can be provided to adapt various differently sized and shaped speakers 1402 to be securely mounted within the speaker housing 1802. In some embodiments, the collar 1902 can be made entirely of flexible, conforming material without an outer shell. The collar 1902 is snap fit onto the speaker 1402 (e.g., on a stem or neck of the speaker) and then the collar 1902 with the speaker 1402, is snap fit between a pair of the griping fingers of the speaker mounting system 1808. As described above with respect to other embodiments, the speaker 1402 can be secured within the speaker housing 1802 in many different ways and any practicable method can be used.
In addition, the integrally formed clip member 1812 that extends from the attachment frame 1814 of the attachment mechanism 1804 includes a press fit barb 1904 that can be inserted into an opening 1906 in the clip member 1812. Upon press fitting the barb 1904 into the opening 1906 in the clip member 1812, the worn item (e.g., a hat brim) is secured within the attachment mechanism 1804. Further, the illustrative example flexure bearing 1816 of the adjustable connector 1806 can include a foam rubber block 1908 and a bendable wire 1910 as with other embodiments described above. Assembly of the various components can be by any practicable means such as epoxy, welding, snap fit fittings, etc. FIG. 19B depicts the assembled left side 1800A of the wearable personal sound speaker system kit 1800 with an ear-bud speaker 1402 installed using the collar 1902 and including the speaker wire 1208 routed through the speaker wire channel 1810 of the speaker housing 1802.
FIGS. 20A, 20B, and 20C depict two side views and one bottom view respectively of the left side 1800A of the wearable personal sound speaker system kit 1800 of FIG. 18A. These drawings illustrate the adjustability features of the kit. The solid arrow in FIG. 20A depicts the direction that the speaker housing 1802 can be extended away from the attachment mechanism 1804. The extended position is shown in phantom. The double ended arrow 2002 in FIG. 20B illustrates the direction of up and down position adjustments that can be made to the speaker housing 1802 relative to the attachment mechanism 1804. Higher (e.g., adjusted up) and lower (e.g., adjusted down) example positions of the speaker housing 1802 are indicated in phantom.
In addition, the arc arrows 2004 in FIG. 20B indicate the rotational adjustments that can be made to the orientation of the speaker housing 1802 relative to the attachment mechanism 1804. Note also that the speaker 1402 can be rotationally adjusted within the speaker housing 1802 as indicated by arc arrow 2006. These adjustability features insure that sound emanating from the speaker 1402 can be directed to the user's ear canal even when the speaker housing 1802 is positioned to not cover the user's ear. Thus, embodiments of the present invention allow a user to hear sound from the speakers with acceptable fidelity and volume and also allow the user to hear sounds from the surrounding environment.
The double ended arrow 2008 in FIG. 20C illustrates the direction of in and out position adjustments that can be made to the speaker housing 1802 relative to the attachment mechanism 1804. Wider (e.g., adjusted out) and closer (e.g., adjusted in) example positions of the speaker housing 1802 are indicated in phantom.
Turning now to FIGS. 21A and 21B, front perspective views of the wearable personal sound speaker system kit 1200 of FIG. 12 being worn in two different positions are illustrated. Note that the following description is equally applicable to the embodiment of the kit 1800 depicted in FIGS. 18A and 18B. In some instances, a user may prefer the improved fidelity and volume achievable by having the speakers 1402 relatively close to the user's ears 1302 while still enjoying the increased safety benefits of being able to hear sounds from the surrounding environment. In such instances, the embodiment depicted in FIG. 21A may be best suited to achieve the user's desires. The wearable personal sound speaker system kit 1200 as adjusted in FIG, 21A allows the user to clearly hear both sound from the speakers and the environment because neither the speaker 1402 nor the kit 1200 contacts the user's ears and no part of the system is in the user's ears.
In other instances however, the user may be required to not have anything blocking or covering their ears. For example, a running race may have rules that not only require the competitors to not use any device that is inserted in the ear or contacts the ear, the rules may specify that the competitor's ear must not be blocked or covered. In such circumstances, embodiments of the invention configured as depicted in FIG. 21B may be useful. In FIG. 21B, the speaker housings 1210 are adjusted (e.g., rotated) out and away from the user's ears at an approximately 30 degree angle so that the ears are not blocked or covered. In alternative embodiments, the speaker housings 1210 can be rotated out 45 degrees or up to 90 degrees or more. Note that the speakers 1402 can be angled to compensate for the position of the speaker housings 1210 and sound from the speakers can still be directed at the user's ear canal. More specifically, note that in both configurations depicted in FIGS. 21A and 21B, the face of the speakers 1402 are adjusted to direct sound at the user's ear canals even though the speaker housings 1210 are at different angles relative to the sides of the user's head.
Accordingly, while the present invention has been disclosed in connection with the preferred embodiments thereof, it should be understood that other embodiments may fall within the spirit and scope of the invention, as defined by the following claims.
