DETAILED DESCRIPTION

(12) The presently disclosed subject matter addresses problems encountered in communicating using conventional mouthguards, including systems and devices. These systems and devices are configured to allow for wireless audio communication between a remote data source and a user of the mouthguard, with the mouthguard inserted into the user's mouth and contacting the user's teeth. The mouthguard is configured to transmit an audio signal to a user, the audio signal being transmitted to the user via bone conduction through the user's teeth. The following example embodiments are provided for purposes of illustrating the subject matter and are not intended to be interpreted as in any way limiting the scope of the subject matter claimed.

(13) FIGS. 1 through 11 illustrate various views, aspects, and/or features associated with wirelessly communication configured mouthguard devices and systems. In some embodiments, the wireless communication configured mouthguard devices and systems set forth herein are configured to receive a data transmission, process the data transmission, and transmit the data transmission in an audio format to the user via bone conducting speakers.

(14) Referring to FIGS. 1 through 4, a first example embodiment of a mouthguard, generally designated 100, is shown. The mouthguard 100 is configured for wireless communication from a remote source (200, See FIGS. 10 and 11). The mouthguard 100 has an outer portion 110 configured to interface with an outer surface of the teeth of the user when in an installed position, an inner portion 114 configured to interface with an inner surface of the teeth of the user when in the installed position, and a bottom portion 112 configured to interface with a bottom surface of the teeth of the user when in the installed position.

(15) According to the first embodiment, the outer portion 110 has speaker protrusions 116 on the outside of each lateral end of outer portion 110. Speakers 120 configured to transmit sound to a user via bone conduction are located at least partially within each speaker protrusion 116. Speakers 120 are shown as being embedded within an inner layer outer portion 110 of mouthguard 100 and are therefore separated from direct contact with the user's teeth, however speakers 120 may be configured to make direct contact with the user's teeth in other embodiments. Speakers 120 can be connected to a controller, generally designated 130, by connecting wires 124.

(16) Controller 130 is configured to receive an audio signal from one or more wireless antennas either integrated within controller 130 or otherwise embedded within the mouthguard, to perform any necessary processing of the audio signal, and to send the processed audio signal to speakers 120 in a compatible format, preferably a digital format. Controller 130 can include or be in electrical communication with any suitable antenna, such as for example a BLUETOOTH antenna 140 and/or a WiFi antenna 138, both of which are preferably located at a front portion of outer portion 110. While BLUETOOTH antenna 140 and WiFi antenna 138 are shown as being integral with or mounted onto controller 130, they may be located remote from and connected to controller 130 in order to ensure their optimal placement for receiving incoming data signals. Controller 130 further has a System-on-Chip 134 (SoC), which has a processor and memory onboard the SoC, as well as an onboard storage device 136 and a power storage device 136.

(17) Mouthguard 100 can further include an external port 150, behind which can be an external port connector 154. External port 150 is configured to, in a closed position, seal external port connector from moisture and particulate intrusion during use. When external port is in an open position, external port connector 154 is connected to controller 130 and is configured to receive data and/or power from a wired source (e.g., wired source 180 shown in FIG. 9) via a wired connection (e.g., cable 160 shown in FIG. 9). External port connector 154 can be, for example, a micro-USB connector. Data and/or power received by mouthguard 100 by external port connector 154 can be transmitted and stored within an onboard storage device and a power storage device, respectively. External port 150 and external port connector 154 are shown as being offset from a central plane of symmetry in mouthguard 100, but any placement of external port 150 and external port connector 154 is envisioned.

(18) Power storage device can be an internal battery, a capacitor, or any other suitable device. Onboard storage device can be a flash memory device, or any other suitable storage device.

(19) The controller 130 is configured to transmit a same audio signal to both speakers 120 or to transmit a different audio signal to both speakers 120. Furthermore, controller 130 is configured to transmit different audio signals from different sources to each speaker 120. For example, controller 130 can be configured to send right speaker 120 a wirelessly transmitted signal while simultaneously sending left speaker 120 an audio signal stored in onboard storage device.

(20) Referring now to FIG. 5, a mouthguard, generally designated 101, according to a second embodiment with only a single speaker 120 is shown. Mouthguard 101 is similar to mouthguard 101 in structure and functionality, however only one speaker protrusion 116 is provided rather than two speaker protrusions 116 in the first embodiment. As such, mouthguard 101 is only capable of transmitting a single audio source to the user at any given time via speaker 120. Mouthguard 101 has a controller 130 configured to receive, process, and transmit a single audio signal to the user. Just as in the first embodiment, controller 130 of mouthguard 101 has an external port 150, with an external port connector 154 being located behind external port 150, a power storage device 132, an SoC 134, an onboard storage device 136, a WiFi antenna 138, and a BLUETOOTH antenna 140 which are shown as being mounted on controller 130. Unlike controller 130 of mouthguard 100, controller 130 of mouthguard 101 shows that BLUETOOTH antenna 140 is located adjacent to external port 150.

(21) Referring to FIG. 6, a mouthguard, generally designated 102, according to a third embodiment is shown. Mouthguard 102 has two speakers 120 which are embedded within an inner layer of bottom portion 112. As such, speakers 120 are configured to transmit an audio signal into the bottom surface of a user's teeth. Just as in the first embodiment, speakers 120 are connected to controller 130 by connecting wires 124. Controller 130 is connected to external port connector 154 by external port wire 152. External port connector 154 is covered by external port 150 when in a closed position. External port wire 152 is configured to transmit data and power from external port connector 154 to controller 130.

(22) Just as with mouthguard 100, controller 130 of mouthguard 102 is configured to receive a data transmission from one or more antennas, process the data signal into an audio signal, and transmit an audio signal to one or both of speakers 120. Controller 130 of mouthguard 102 is configured to transmit different audio signals to each of speakers 120. Controller 130 has a power storage device 132, an SoC 134, and an onboard storage device 136 integrated thereon. BLUETOOTH antenna 140 and WiFi antenna 138 are shown as being discrete components which are connected to controller 130, the antennas being molded into a front section of outer portion 110, adjacent to external port 150 to ensure optimal signal reception.

(23) Referring to FIG. 7, a mouthguard, generally designated 103, according to a fourth embodiment is shown. Mouthguard 103 is configured with a speaker 120 which is integral with controller 130, both of which are molded within bottom portion 112 of mouthguard 103. Controller 130 and speaker 120 are preferably disposed on one lateral portion of mouthguard 103, but can be located in any location where mouthguard 103 contacts the user's teeth. Controller 130 is configured to work as is described in the other embodiments and is connected to external port connector 154 by external port wire 152. Just as in mouthguard 102, controller 130 of mouthguard 103 has a power storage device 132, an SoC 134, and an onboard storage device 136 integrated thereon. Because of the location of controller 130 being located away from a front section of outer portion 110, it is preferable that BLUETOOTH antenna 140 and WiFi antenna 138 be located along the front section of outer portion 110 of mouthguard 103 to ensure satisfactory antenna performance. As such, just as external port connector 154 is connected to controller 130 via an embedded external port wire 152, both BLUETOOTH antenna 140 and WiFi antenna 138 are connected to controller 130 by embedded conductive wires. It is also contemplated that a single wire may be used to connect one or more of external port connector 154, BLUETOOTH antenna 140, and WiFi antenna 138 to controller 130. The integration of controller 130 and speaker 120 enable a simplified assembly process and also reduce the likelihood of failure from fracture of one of connecting wires 124 which are present in the other three embodiments.

(24) FIG. 8 shows an optional tether 170 removably but rigidly connected to external port 150 of a mouthguard 102. Tether 170 is configured to be attached to any of mouthguards 100-103, as well as any other embodiment of a mouthguard as enabled by the features discussed herein. Tether 170 is configured to attach to retention features of external port 150 in such a way as to not be dislodged without the retention features being deactivated such as, for example, by pressing a button to retract the retention features. Tether 170 may also be inserted and retained within mouthguard 102 via an interference fit. Tether 170 may be designed such that tether 170 will mechanically fail before the retention features of external port 150, thereby reducing the likelihood of mouthguard 102 being damaged when tether 170 is dislodged; by this feature, a new tether 170 can be attached to mouthguard 102 when an old tether 170 breaks rather than requiring replacement of the entire mouthguard 102. Tether 170 allows mouthguard 103 to be connected to a structure (e.g., a football helmet, not shown) in order to prevent the mouthguard from falling to the ground in case of being dislodged from the user's mouth, thereby reducing the chances of mouthguard 102 being damaged.

(25) FIG. 9 shows a cable 160, configured to communicate with wired source 180, transmitting data and/or power to mouthguard 103 from wired source 180 to be stored in onboard storage device and/or power storage device, respectively. Just as with tether 170, cable 160 is configured to be attached to any of mouthguards 100-103, as well as any other embodiment of a mouthguard as enabled by the features discussed herein. Cable 160 is configured to attach to retention features of external port 150 in such a way as to not be dislodged without the retention features being deactivated. Cable may also be configured with no retention features, such that cable 160 can be unplugged from external port connector 154 with only minimal extraction force being required.

(26) FIG. 10 shows an example system, including an external source 200 which transmits a data signal to mouthguard 100 via a wireless communication protocol (e.g., BLUETOOTH). FIG. 11 shows a further example system, including external source 200 being connected to an external network 300, which then wirelessly transmits the data signal to mouthguard 100. It should also be noted that external source may be configured to transmit a data signal to a plurality of mouthguards 100 and, furthermore, to select any of the plurality of mouthguards 100 to receive the data signal.

(27) Other embodiments of the current invention will be apparent to those skilled in the art from a consideration of this specification or practice of the invention disclosed herein. Thus, the foregoing specification is considered merely exemplary of the current invention with the true scope thereof being defined by the following claims.
