CROSS-REFERENCE TO RELATED APPLICATIONS 
     This nonprovisional application is a continuation of and claims priority to provisional application No. 61/935,035, entitled “SHOUT STOPPER,” filed Feb. 3, 2014 by the same inventor. 
    
    
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates, generally, to an alerting device. More specifically, it relates to a headphone adapter designed to alert a headphone user or more than one headphone users when another individual is attempting to communicate with the headphone user(s). 
     2. Brief Description of the Prior Art 
     In this day and age, audio devices and headphones have become common accessories. While many benefits stem from headphones, issues have arisen in communicating with individuals using headphones. The party attempting to communicate with a headphone user is often unable to gain the attention of the headphone user due to headphones&#39; inherent ability to block out external noise by transmitting audio. Resultantly, the communicating party is forced to gain the user&#39;s attention through shouting, visual contact, or physical contact, which could easily annoy either party. 
     Currently, there exists technology to gain the attention of headphone users when they are receiving an incoming phone call, such as U.S. patent application Ser. No. 11/165,887 to Wainwright. However, this technology is designed to inform a headphone user when he/she is receiving a phone call. It does not enable an individual to gain the attention of a headphone user without calling the headphone user&#39;s cellular telephone. 
     Accordingly, what is needed is a simple and inexpensive system adapted to enable an individual to gain the attention of a headphone user without either party having to use a cell phone. However, in view of the art considered as a whole at the time the present invention was made, it was not obvious to those of ordinary skill in the field of this invention how the shortcomings of the prior art could be overcome. 
     All referenced publications are incorporated herein by reference in their entirety. Furthermore, where a definition or use of a term in a reference, which is incorporated by reference herein, is inconsistent or contrary to the definition of that term provided herein, the definition of that term provided herein applies and the definition of that term in the reference does not apply. 
     While certain aspects of conventional technologies have been discussed to facilitate disclosure of the invention, Applicants in no way disclaim these technical aspects, and it is contemplated that the claimed invention may encompass one or more of the conventional technical aspects discussed herein. 
     The present invention may address one or more of the problems and deficiencies of the prior art discussed above. However, it is contemplated that the invention may prove useful in addressing other problems and deficiencies in a number of technical areas. Therefore, the claimed invention should not necessarily be construed as limited to addressing any of the particular problems or deficiencies discussed herein. 
     In this specification, where a document, act or item of knowledge is referred to or discussed, this reference or discussion is not an admission that the document, act or item of knowledge or any combination thereof was at the priority date, publicly available, known to the public, part of common general knowledge, or otherwise constitutes prior art under the applicable statutory provisions; or is known to be relevant to an attempt to solve any problem with which this specification is concerned. 
     BRIEF SUMMARY OF THE INVENTION 
     The long-standing but heretofore unfulfilled need for a simple and inexpensive system adapted to enable an individual to gain the attention of a headphone user without either party having to use a cell phone is now met by a new, useful, and nonobvious invention. 
     The novel structure includes an alert receiver and an alert transmitter. The alert receiver having a female connection port adapted to mate with an audio output device and a male input adapted to mate with an audio source, such that an audio output path exists between the audio output device and the audio source. The alert receiver also includes a receiving module in communication with an alerting module. 
     The alert transmitter has a manually triggered activator that causes the transmission of a wireless signal, preferably through a predetermined radio frequency, when triggered. The receiving module is adapted to receive the wireless signal from the alert transmitter and communicates the receipt to the alerting module, which in turn alerts the user of the audio output device. 
     The audio output device is preferably a pair of headphones and the alerting module preferably alerts the user of the audio output device by temporarily cutting the connection of the audio output path between the audio output device and the audio source. In a certain embodiment, the alerting module alerts the user of the audio output device by passing a tone to the user through the audio output path. In another embodiment, the alert transmitter may be adapted to record voice input and relay a signal to the alert receiver containing the recorded voice input, such that the alert receiver alerts the headphone user with the recorded voice input. 
     These and other important objects, advantages, and features of the invention will become clear as this disclosure proceeds. 
     The invention accordingly comprises the features of construction, combination of elements, and arrangement of parts that will be exemplified in the disclosure set forth hereinafter and the scope of the invention will be indicated in the claims.

     DETAILED DESCRIPTION OF THE INVENTION 
     In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings, which form a part thereof, and within which are shown by way of illustration specific embodiments by which the invention may be practiced. It is to be understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the invention. 
     The present invention provides a system for alerting a user, listening to an audio output generated from an audio source, that another individual is attempting to get the user&#39;s attention. The present invention provides an alternative alerting system that can be used without a cell phone for situations such as a parent trying to get a child&#39;s attention when the child is listening to headphones in another room. This is a simple and inexpensive alternative to the existing technology requiring another individual to call the headphone user&#39;s phone before the technology sends an alert to the headphone user. The alert may include, but is not limited to, an interruption in the audio signal to the audio output, a reduction in the volume of the audio output, and/or a low-level tone that occurs over top the audio output or in place of the audio output. The audio source may include any device known to a person having ordinary skill in the art that transmits audio and the audio output may include any device known to a person having ordinary skill in the art capable of outputting audio. 
     The present invention includes an alert transmitter and an alert receiver adapted to communicate with one another. The alert receiver is designed to communicate with the audio output device, such as headphones, to alert the user of the audio output device that another individual is attempting to communicate with the user. 
     Example 
     As shown in  FIG. 1 , a certain embodiment includes alert receiver  102  having a female connection port or female jack  104  and a male input or male jack  106 . Female jack  104  is adapted to mate with male input or male jack  108  from headphones  110 . Male jack  106  of alert receiver  102  is adapted to mate with female jack  112  of audio source  114  as shown in  FIG. 2 . The abovementioned connections provide an audio output path starting at audio source  114 , passing through alert receiver  102 , and to headphones  110 . In a certain embodiment, female jack  104  and male jack  106  are each in a standard 3.5 mm headphone/stereo plug format. 
     Alert transmitter  116  includes activator  118  in the form of a button, which activates a wireless communication receivable by alert receiver  102 . As shown in  FIG. 3 , alert transmitter  116  is adapted to wirelessly communicate with alert receiver  102  when activator  118  is initiated. Activator  118  is a momentary switch designed to complete the circuit between power source  122  and radio frequency transmitter  124 . The completion of the circuit enables radio frequency transmitter  124  to emit the predetermined signal from transmitting antenna  126 . 
     Alert receiver  102  includes a receiving module  128  in communication with receiving antenna  120 . Receiving module  128  may include but is not limited to a radio receiver tuned to a specific frequency, a Bluetooth radio receiver, or an 802.11 radio receiver. Receiving module  128  is adapted to receive the particular signal sent via alert transmitter  116 . 
     Alert receiver  102  further includes alerting controller  130  that communicates with receiving module  128  and controls alerting module  132 . Alerting module  132  is adapted to interrupt the audio output path  134  and cut the sound from the audio source to headphones  110 . In a certain embodiment, alerting module  132  may include a circuit to generate a low-level tone. Alert receiver  102  also contains power source  136  and power-saving circuit  138  to trigger a sleep mode when headphones  110  are not receiving an audio signal from audio source  114 . In another embodiment, alert receiver  102  may rely on power received through the connection to audio source  114 . 
     Depending on the type of receiving module employed by alert receiver  102 , alert transmitter  116  communicates with alert receiver  102  through a corresponding signal via radio frequency, Bluetooth, or 802.11. In a certain embodiment, alert receiver  102  and/or alert transmitter  116  may include circuitry to enable LAN, WAN, or internet based communications. 
     Alert receiver  102  is an intermediate connection between audio source  114  and headphones  110 , maintaining the audio path connection  134 . When receiving module  120  receives a wireless signal from alert transmitter  116 , an electronic signal is sent to alerting module  130  and an alert is passed to headphones  110  user through audio output path  134 . In a certain embodiment, the alert receiver may connect with the headphones and/or the audio output device as an adjacent connection and not as a direct line through the audio output path. 
     In a certain embodiment, the alert may remain consistent during the time period in which the alert receiver  102  is receiving a transmission from the alert transmitter  116 . Thus, the operator of alert transmitter  116  can maintain the alert for a desired period of time by continuing to engage activator  118 . In another embodiment, the alerting module in the alert receiver  102  may include a component, known to a person having ordinary skill in the art, that is adapted to initiate the alert for a predetermined period of time after receiving a transmission from alert transmitter  116 . In a certain embodiment, alert transmitter  116  may include a component, known to a person having ordinary skill in the art, that enables alert transmitter  116  to continuously transmit the signal to alert receiver  102  for a predetermined amount of time after activator  118  has been triggered. 
     Such an embodiment would also include the alerting module in alert receiver  102  maintaining the alert while continuing to receive communications from alert transmitter  116 . 
     In a certain embodiment, a single alert transmitter may be adapted to alert a plurality of alert receivers all at once and/or one at a time. This embodiment would be particularly useful for situations such as a classroom teacher using one button to trigger an alert for multiple students&#39; headsets. In another embodiment, the alert transmitter may include several triggers wherein each trigger is adapted to communicate with a certain receiver or subset of receivers.
