Description:
PRIORITY TO RELATED APPLICATIONS 
       [0001]    This is a U.S. Utility Application which claims the benefit of U.S. Provisional Application No. 61/252,096 filed Oct. 15, 2009, the entire contents of which are incorporated herein by reference. 
     
    
     BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The present invention generally relates to a wireless audio system. More specifically, the present invention relates to a wireless lanyard that wirelessly electronically couples an audio output device such as a headphone, earphones, an ear bud and the like to an electronic audio source. 
         [0004]    2. Background Information 
         [0005]    Many electronic devices and audio systems are equipped with a receptacle or jack adapted to receive a plug, a jack or another similar electrical connector for coupling an audio output apparatus such as headphones, earphones, ear buds or the like to the device. Many of these electronic devices such as radios, compact disc players, iPods, telephones and certain televisions are portable and intended for use while the user is mobile. Other electronic devices are stationary but are generally employed while the user is at a distance from the device, e.g., televisions or home stereo equipment. The wire or wires extending from the headphones or ear buds may present a problem to the user of either type of system. With the portable device, the wire or wires often restrict the user&#39;s mobility. With the stationary device, the wire or wires restrict the distance from the audio system that the user may utilize headphones or ear buds. 
         [0006]    U.S. Pat. Nos. 4,845,751, 5,771,441 and 5,974,304 disclose systems that provide a transmitter connected to an electronic device, thereby enabling the electronic device to communicate with headphones having an antenna. Other prior art systems, such as those disclosed in U.S. Pat. Nos. 4,369,521 and 7,558,607, convert the connector cable extending from the headphones into an antenna. However, these systems do not provide a means to support a connector and wireless receiver such that the user&#39;s mobility is not restricted. 
         [0007]    U.S. Pat. No. 4,430,757 discloses a support apparatus for a transmitter. However, the support apparatus is not connectable to headphones or ear buds and is incapable of providing a communication link to deliver an audio signal to headphones or ear buds. A belt for attaching a transceiver to the waist of a user is provided in U.S. Pat. No. 6,522,765. However, the belt along with the cable from the headset restrict the user&#39;s movement. 
         [0008]    In view of the foregoing, it will be apparent to those skilled in the art that a need exists for a wireless audio system having a lanyard that will provide the electronic coupling between an audio system and an audio output device and permit a wide range of mobility for the system user. This invention addresses this need as well as other needs, which will become apparent to those skilled in the art from this disclosure.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0013]    Preferred embodiments of the present invention will now be explained with reference to the drawings. It will be apparent to those skilled in the art from this disclosure that the following description of the embodiments of the present invention is provided for illustration only and not for the purpose of limiting the invention as defined by the appended claims and their equivalents. 
         [0014]    Referring initially to  FIGS. 1 and 2 , a wireless audio system is shown generally at  100 . The audio system  100  includes a wireless lanyard  1  adapted to be worn or otherwise carried by a user of the audio system. The wireless lanyard  1  includes a preferably thin, lightweight cable material having cable connectors  2  and sliding cable locks  4 . The cable connectors  2  together with the sliding cable locks  4  enable a user to adjust the size of the wireless lanyard  1 , but create enough resistance to lock the wireless lanyard  1  in place once the user adjusts it to a desired position. The wireless lanyard  1  further includes a connector or headphone plug, by way of example; a female electrical receptacle  6  structured and arranged to be releasably electronically connected to a jack  8  of an audio output device, which, for purposes of illustration, may be a pair of headphones  10 . It is to be understood that the audio output device may also be in the form of earphones, ear buds, audio earplugs and the like without departing from the scope of the present invention. The wireless lanyard  1  also includes a receiver  12  for wireless communication with an adapter  14  operatively connected to an electronic device or audio source, the operation of which will be described in greater detail below. 
         [0015]    The adapter  14  plugs into a connector in an electronic device such as a television, stereo system, radio, compact disc player (CD player), tape player, telephone, MP3 player, iPod or iPhone (not shown), for example, thereby enabling the electronic device to wirelessly communicate with the receiver  12 . Preferably, the adapter  14  includes a transmitter that provides wireless communication via a radio frequency (RF) signal and/or short wavelength radio transmissions such as those provided by Bluetooth communication devices. The receiver  12  is configured to receive wireless communication via RF and/or Bluetooth from the adapter. Upon receipt of an audio signal from the transmitter of the adapter  14 , the receiver  12  sends the signal to the headphones  10  via the jack  8  plugged into the headphone plug  6 . Preferably, an audio wire, which runs substantially coaxially through or is integral with the cable of the wireless lanyard  1 , connects the receiver  12  to the headphone plug  6 . 
         [0016]    Thus, the present invention provides a wireless lanyard system that is structured and arranged to enable wireless operation of an audio output device such as a headphone or headset  10 . The headphones  10  can be standard headphones with a standard cable or can be headphones  10  made especially for the wireless lanyard  1 . That is, the headphones  10  can include a shortened cable for running to the wireless lanyard  1 , which is preferably worn around the neck of the user. 
         [0017]      FIG. 3  illustrates another embodiment of a wireless lanyard  101 . In this embodiment, the lanyard includes two headphone plugs  106  for the user&#39;s convenience. 
         [0018]    In understanding the scope of the present invention, the term “comprising” and its derivatives, as used herein, are intended to be open-ended terms that specify the presence of the stated features, elements, components and/or groups, but do not exclude the presence of other unstated features, elements, components and/or groups. The foregoing also applies to words having similar meanings such as the terms, “including”, “having” and their derivatives. The terms of degree such as “substantially”, “about” and “approximate” as used herein mean a reasonable amount of deviation of the modified term such that the end result is not significantly changed. For example, these terms can be construed as including a deviation of at least±5% of the modified term if this deviation would not negate the meaning of the word it modifies. 
         [0019]    While only selected embodiments have been chosen to illustrate the present invention, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made herein without departing from the scope of the invention as defined in the appended claims. For example, the size, shape, location or orientation of the various components can be changed as needed and/or desired. Components that are shown directly connected or contacting each other can have intermediate structures disposed between them. The functions of one element can be performed by two, and vice versa. The structures and functions of one embodiment can be adopted in another embodiment. It is not necessary for all advantages to be present in a particular embodiment at the same time. Thus, the foregoing descriptions of the embodiments according to the present invention are provided for illustration only, and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.
