The multifunctional earphone device 100 (hereinafter invention) comprises a housing 101, a plurality of earphones 102, a volume control 103, an audio source control 104, a charger 105, a USB cable plug 123, a first retractable spool 107, and a second retractable spool 108. The invention 100 is a multifunctional device adapted for use with personal data devices. Specifically, the invention 100 is a housing 101 that contains a plurality of earphones 102, a control system to remotely control the personal data device, and a power distribution system designed to charge personal data devices.
The housing 101 is a casing that is used to contain the invention 100. The housing 101 further comprises a rigid case 111, a key ring 112, a belt clip 113, a first flap 114, and a second flap 115. The belt clip 113 further comprises a pivot 116 and a spring clip 117. The rigid case 111 is a container made of a rigid material. The rigid case 111 contains, or has mounted on it, the remaining components of the invention 100. The key ring 112 is a loop that is formed in the rigid case 111. The key ring 112 allows users to attach fasteners, such as a carabiner, to the invention 100. The belt clip 113 further comprises a pivot 116 and a spring clip 117. The spring clip 117 is attached to the rigid case 111 using the pivot 116. The pivot 116 allows the spring clip 117 to rotate freely using the pivot 116 as a pivot point. The spring clip 117 allows the housing 101 to be secured a strap or other belt like object. The housing 101 further comprises a first earphone port 141, a second earphone port 142, a USB A port 122, a plug channel 143, and a jack port 144.
The first earphone port 141, the second earphone port 142, the USB A port 122, the plug channel 143, and the jack port 144 are all apertures that provide access to the functionality of the invention 100 that is contained within the housing 101. The first earphone port 141, the second earphone port 142, the USB A port 122, the plug channel 143, and the jack port 144 are all discussed elsewhere in this disclosure. The first flap 114 is a flexible cover that is used to close the first earphone port 141 when the first earphone 131 is stored within the housing 101. The second flap 115 is a flexible cover that is used to close the second earphone port 142 when the second earphone 132 is stored within the housing 101.
The charger 105 further comprises prongs 121 and a USB A port 122. The prongs 121 are two metal prongs that are NEMA 5-15 compliant electrical connectors that can be used to connect the invention 100 to the national electric grid. The prongs 121 are stored in the plug channel 143. The plug channel 143 is a cavity formed in the surface of the rigid case 111 that is sized to receive the prongs 121 when the prongs 121 are not in use. The prongs 121 are hinged such that the prongs 121 can be rotated away from the plug channel 143 such that the prongs 121 project perpendicularly away from the surface of the rigid case 111. In this position, the prongs 121 can be plugged into an electrical socket to draw power from the national electric grid. Electric power received from the national electric grid is then rectified, conditioned, and the voltage is adjusted such that the electric power can be used to power personal data devices. Methods to rectify, condition, and adjust the voltages of electric power are well known and documented in the electrical arts.
The USB A port 122 is a second power connection that allows the invention 100 draw electric power from electronic devices through the use of a USB A compatible cable and plug attached to an external electronic device. The USB A port 122 is mounted in the plug port 145 of the rigid case 111. The power provided to the invention 100 through the USB A compatible cable and plug is already suitable for use by personal data devices and needs no further conditioning. Methods to switch electric power distribution between two power sources are well known and documented in the electrical arts.
The housing 101 contains the first retractable spool 107 and the second retractable spool 108. The first retractable spool 107 is a commercially available spring loaded spool that is used to store the earphones 102. The earphone 102 further comprises a first earphone 131, a second earphone 132, an earphone cable 133, and an earphone jack 134. The earphone cable 133 is loaded onto the first retractable spool 107 such that both the first earphone 131, the second earphone 132, and the earphone jack 134 can be extended out of the housing 101 through the first earphone port 141, the second earphone port 142, and the jack port 144 respectively. The first retractable spool 107 is designed such that the spring of the first retractable spool 107 is placed under tension when the first earphone 131, the second earphone 132, and the earphone jack 134 are extended out of the housing 101.
When the first earphone 131, the second earphone 132, and the earphone jack 134 are to be retracted back into the housing 101, the spring will provide the motive force required to rewind the earphone cable 133 onto first retractable spool 107. Methods to feed a cable on a retractable spool such that both ends of the cable can be extended and retracted are well known and documented in the art. The second retractable spool 108 is a commercially available spring loaded spool that is used to store the USB cable plug 123. The USB cable plug 123 is a cable and plug that provides electrical power from the charger 105 to a personal data device. The USB cable plug 123 is stored on the second retractable spool 108 such that the USB cable plug 123 can be extended through the jack port 144. The second retractable spool 108 is designed such that the spring of the second retractable spool 108 is placed under tension when the USB cable plug 123 is extended out of the housing 101. When the USB cable plug 123 is to be retracted back into the housing 101, the spring will provide the motive force required to rewind the earphone cable 133 onto the second retractable spool 108.
The earphones 102 are associated with the operation of the volume control 103 and the audio source control 104. The volume control 103 further comprises a volume up button 135 and a volume down button 136. The volume up button 135 sends a signal to the personal data device over the earphone cable 133 to increase the audio volume of the audio file being processed. The volume down button 136 sends a signal to the personal data device over the earphone cable 133 to decrease the audio volume of the audio file being processed. The audio source control 104 further comprises a forward button 137 and a back button 138. The forward button 137 sends a signal to the personal data device over the earphone cable 133 to move to the next audio file. The back button 138 sends a signal to the personal data device over the earphone cable 133 to move to the prior audio source file. Methods to control the operation of personal data devices in this manner are well known and documented in the electrical arts.
To use the invention 100 to listen to an audio file, the earphone jack 134 is plugged into the personal data device and the first earphone 131 and the second earphone 132 are inserted into the ear canals of the wearer. The audio volume generated by the speaker in the first earphone 131 and the speaker in the second earphone 132 is controlled through the use of the volume control 103. The selection of the audio source processed by the personal data device is controlled through the audio source control 104. To use the invention 100 as a charger 105, the invention 100 is connected to either the national electric grid or a USB compatible power source at the user's discretion. The USB cable plug 123 is then plugged into the personal data device that is to be powered.
The rigid case 111 and the key ring 112 are formed as a single unit from molded plastic. Suitable plastics include, but are not limited to, polyethylene or polycarbonate. The remaining components are commercially available.
