Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to earplugs, and more specifically to an earplug providing wireless communication with a mobile device and transmitting sounds through an integrated speaker

2. Discussion of the Related Art

Earplugs are plugs that are inserted into the outer ear canal to block ambient sound and environmental noise. Earplugs are available in various sizes, shapes and materials.

Earplugs are frequently used by people who must sleep in a noisy environment. For example, earplugs are often used by airplane and train passengers traveling on long trips, sometimes overnight, and want to sleep during the trip. Earplugs are also used by people whose sleep is disturbed by ambient noise or a snoring spouse. Ear plugs are also useful to provide protection against hearing loss in a noisy environment such as a construction site or a rock concert.

The noise reduction or cancellation provided by earplugs blocks ambient sounds non-discriminately, which can sometimes have unintended side effects. For instance, those who wear earplugs while sleeping often need to wake up at a certain time and would ideally use an alarm clock to wake up on time. However, the use of earplugs while sleeping would prevent a user from hearing the alarm. In addition, earplugs can block emergency or warning signals, such as generated by a fire or security alarm, and potentially imperil the user.

Solutions to this problem are common in the prior art, and include placing the alarm closer to the user, substituting a vibrating device for the sound alarm, increasing the sound of the alarm, and using a wireless signal to transmit an alarm to a speaker contained within an earplug.

Wireless earplugs are found in the prior art. U.S. Pat. No. 6,067,006 to O'Brien (2000) describes a self-contained alarm and earplug apparatus. However, since the controls for operating the alarm are included on the earplug, the device is bulky and limited in operation.

In U.S. Pat. No. 7,512,247 to Odinak et al. (2009), the inventors include a carrying case that is used to program the wireless earplug for alarm times and sounds. U.S. Patent Application No. 2010/0035648 to Huang (2010) also describes a wireless earplug with a separate control module.

Referring first to FIG. 1, a simplified section of an embodiment of a wireless earplug 100 is shown. Shown are an outside edge 102, an inside edge 104, an ear canal 106, a sound canal bore 108, a speaker 110, an earplug surface 112, a wireless receiver/transmitter module 114, a plurality of connecting circuits 116, an ear 118, an ear drum 120, a speaker grill 122, an on/off switch 124, a first on/off switch end 126, a second on/off switch end 128, an earplug casing 130 and a battery 132.

The wireless earplug 100 is shown wedgingly inserted into the ear canal 106. In the present embodiment, the shape of the wireless earplug 100 is an approximately frustoconical shape with rounded edges. Other shapes may be used for the wireless earplug 100, such as musicians' earplugs or custom-shaped earplugs. The outside edge 102 is the larger generally circular edge of the approximately frustoconical shape and is located distal to the ear canal 106 when inserted into the ear 118. The inside edge 104 is the smaller generally circular edge of the approximately frustoconical shape and is located proximate to the ear drum 120 when inserted into the ear 118. The approximate diameter of the inside edge 104 may vary, but is approximately 9 mm.

The earplug casing 130 comprises rubber, silicone or other material suitable for providing hearing protection and being wedgingly inserted into the ear 118.

The wireless earplug 100 includes the sound canal bore 108. The sound canal bore 108 is generally cylindrical and the center axis of the sound canal bore 108 is approximately the center axis of the wireless earplug 100. The sound canal bore 108 extends from the inside edge 104 of the earplug to a distance approximately one-third to one-half the distance from the inside edge 104 to the outside edge 102. The sound canal bore 108 terminates at the speaker 110. The sound canal bore 108 diameter is less than the diameter of the inside edge 104, by an amount so that enough earplug casing 130 surrounding the sound canal bore 108 remains in order to prevent collapse of the sound canal bore 108 when inserted into the ear 118.

Enclosed within the earplug casing 130 are the battery 132, the wireless receiver/transmitter module 114, the speaker 110, and the plurality of connecting circuits 116.

The wireless receiver/transmitter module 114 is embedded in the earplug casing 130 and is proximate to the outside edge 102. The wireless receiver/transmitter module 114 includes components for transmitting and receiving wireless signals 302, for example Bluetooth signals or short wave radio signals. In the preferred embodiment of the invention, the wireless transmission components of the invention conform to the Bluetooth specification, using a controller 304 (shown below in FIG. 3) as the master device and the wireless earplug 100 as a slave device.

At least one connecting circuit 116 electrically couples the wireless receiver/transmitter module 114 to the speaker 110. The wireless receiver/transmitter module 114 includes components for transmitting audio signals to the speaker 110. The wireless receiver/transmitter module 114 is electrically coupled to the battery with at least one connecting circuit 116. The wireless receiver/transmitter module 114 has an approximate broadcasting range of 10 meters.

The battery 132 is embedded in the earplug casing 130. In the present embodiment, the battery 132 is located proximate to the outside edge 102 when the wireless earplug 100 is inserted in the ear 118. The battery 132 may be rechargeable or non-rechargeable. For a rechargeable battery, the earplug 100 is modified to provide access for a charging device (not shown). If the battery 132 is non-rechargeable, a portion of the earplug casing 130 between the battery 132 and the earplug surface 112 is removable and replaceable in order to allow for replacement of the battery 132.

The battery 132 is of a type suitable for providing power to the electrical components 110, 114, 124, and suitable for enclosing within the wireless earplug 100 in addition to the other necessary components. In the present embodiment, the battery 132 conforms to the Bluetooth Class 2 specification, although other wireless specifications may be used.

The battery 132 is electrically coupled to the wireless receiver/transmitter module 114, the speaker 110, and the on/off switch 124 with at least one connecting circuit 116 to each component 110, 114, 124.

The speaker 110 is embedded in the wireless earplug 100 adjacent to the end of the sound canal bore 108 distal to the ear canal 106 when the wireless earplug 100 is inserted into the ear 118. The speaker grill 122 is located at the end of the sound canal bore 108 distal to the ear canal 106, when the wireless earplug 100 is inserted into the ear 118, so that sound from the speaker 110 is projected through the sound canal bore 108 and into the ear canal 106.

The speaker 110 is electrically coupled to the wireless receiver/transmitter module 114 as detailed above and includes components to electrically receive transmissions from the wireless receiver/transmitter module 114 and broadcast them as audio sounds.

The on/off switch 124 is located within the sound canal bore 108 and is approximately cylindrical in shape. The longitudinal axis of the on/off switch 124 is approximately parallel to the longitudinal axis of the sound canal bore 108. The diameter of the on/off switch 124 is smaller than the diameter of the sound canal bore 108 so that enough void remains to transmit the audio into the ear canal 106. In the embodiment shown, the on/off switch 124 is adjacent to the inside face of the sound canal bore 108.

The first on/off switch end 126 is approximately located at the end of the sound canal bore 108 distal to the ear canal 106 when the wireless earplug 100 is inserted into the ear 118. The second on/off switch end 128 is located inside the sound canal bore 108, and extends far enough into the sound canal bore 108 that the on/off switch 124 may be toggled by a thin wire such as an unbent paperclip, but does not extend past the inside edge 104 of the wireless earplug 100 into the ear canal 106.

The on/off switch 124 is electrically coupled to the battery, as previously described, so that power to the wireless receiver/transmitter module 114 and the speaker 110 is controlled by the on/off switch 124. In the present embodiment, the on/off switch 124 is a toggle switch. Those skilled in the art will note that additional on/off switch 124 configurations are suitable. For example, a tubular on/off switch 124 may be located within the sound canal bore 108 and toggled on/off by using an external implement to press the tubular switch 124 towards the outside edge 102 of the wireless earplug 100.

Referring again to FIG. 2, the wireless earplug 100 is shown in operation in the ear 118.

The wireless earplug 100 is wedgingly inserted into the ear canal 106 far enough to hold the wireless earplug 100 in place during normal activities, but not far enough to damage the ear canal 106. The outside edge 102 and a portion of the wireless earplug 100 adjacent to the outside edge 102 remains outside the ear canal 106.

The wireless earplug 100 thus provides hearing protection to the ear 118, while functioning to receive wireless signals 302 and transmit them to the speaker 110. A user is then able to hear certain sounds while maintaining the hearing protection. The operation of the wireless earplug system 300 is described further below.

Referring next to FIG. 2, a perspective view of the exterior of the wireless earplug 100 is shown. Shown are the wireless earplug 100, the sound canal bore 108, the on/off switch 124, the inside edge 104, the outside edge 102, and the first on/off switch end 126.

The wireless earplug 100 is shown in an uninserted state. As previously described in FIG. 1, the earplug is an approximate frustoconical shape. The earplug is shown with the outside edge 102 on the left-hand side and the inside edge 104 on the right-hand side.

As shown, the sound canal bore 108 is visible at the inside edge 104 of the wireless earplug 100. A portion of the on/off switch 124, including the first on/off switch end 126, is visible in the sound canal bore 108. The other wireless earplug 100 components 110, 114 are inside the wireless earplug 100 and thus are not visible in FIG. 2.

Referring next to FIG. 3, a simplified schematic diagram of a wireless earplug system 300 is shown. Shown are the wireless earplug 100, the wireless receiver/transmitter module 114, the speaker 110, a plurality of wireless signals 302, the controller 304, and a graphical user interface 306.

The wireless earplug 100 shown in FIG. 3 is a simplified diagram of the wireless earplug 100 previously shown in FIGS. 1 and 2. Shown are the wireless receiver/transmitter module 114 and the speaker 110. Other components are not shown in FIG. 3 for clarity.

The wireless receiver/transmitter module 114 is electrically coupled with and transmits audio signals to the speaker 110, as shown in FIG. 1. The wireless receiver/transmitter module 114 sends and receives wireless signals 302 to and from the controller 304.

The controller 304 may be any device with components for running computer programs and transmitting and receiving wireless signals 302 compatible with the wireless earplug 100. In the embodiment shown, the controller 304 is a smartphone, but many devices are currently available or may be adaptable for use with the wireless earplug 100. Additional adaptable devices include personal computers, baby monitors, music players, and tablet computers.

The controller 304 has an approximate range for wireless receiving and transmitting of about 10 meters. The controller 304 also includes means for limiting the volume of the transmitted audio below a certain decibel level in order to prevent any hearing damage when the wireless earplug 100 is inserted into the ear 118.

The wireless signals 302 sent to the wireless earplug 100 are controlled through the graphical user interface 306. The graphical user interface 306 may be configured for various embodiments. One embodiment as shown below in FIG. 5 is to transfer an audio alarm to the wireless earplug 100. Another embodiment would transmit controller audio output, for example audio files, streaming audio or audio phone calls. Yet another embodiment utilizes a controller 304 microphone to transmit ambient audio, for example, as an assistive listening device. An exemplary assistive listening device usage includes the controller microphone placed near a television speaker and transmitting the television audio to the wireless earplug 100. In this manner, the wireless earplug 100 user can adjust the television audio volume without changing the television settings. Yet another embodiment of the present invention includes using the controller 304 as a filtering device, transmitting audio based on certain criteria set using the graphical user interface 306 or as pre-determined settings. Criteria examples include filtering audio phone calls based on the identity of the caller, and allowing high-decibel ambient audio, such as a fire alarm, to be transmitted to the wireless earplug 100.

The user interacts with the graphical user interface 306 to set the requirements for audio transmissions. The requirements may include, for example, volume control, time of an alarm (as shown below in FIG. 5), phone call rings, phone call audio, and audio email notifications.

The controller 304 may also be configured for pairing the controller 304 with the wireless earplug 100, as in the case of Bluetooth devices.

In operation, the wireless earplug 100 is inserted into the ear 118. The user uses the graphical interface to set parameters for sound transmission, for example time and duration of sound. The controller 304 then sends the wireless signals 302 to the wireless earplug 100 according to the previously set parameters. The wireless receiver/transmitter module 114 receives the wireless signals 302 and transmits them to the speaker 110. The speaker 110 outputs the transmissions as audio sounds, which then travel through the sound canal bore 108 in to the ear canal 106, where they are heard by the user.

Referring next to FIG. 4, a schematic block diagram of the controller 304 is shown. Shown are the controller 304, the graphical user interface 306, a programmable logic controller (PLC) 400, an earplug program 402, a memory 404, and a wireless transmitter/receiver module 406.

The PLC 400 includes components necessary for operation of the controller 304 and running of the earplug program 402. The PLC 400 is electrically coupled to the earplug program 402, the graphical user interface 306, the memory 404, and the wireless transmitter/receiver module 406.

The controller 304 also includes the memory 404 for storing data. The memory 404 may be of any type as required for operation of the earplug program 402. The memory 404 also stores the earplug program 402. The memory 404 is electrically coupled to the PLC 400.

The earplug program 402 comprises a programming language compatible with the controller PLC 400, for example the Objective-C programming language for a PLC 400 with an iOS operating system. The earplug program 402 contains programming suitable for carrying out desired tasks, for example inputting and executing an alarm as shown in FIG. 5.

The wireless transmitter/receiver module 406 is electrically coupled to the PLC 400. The wireless transmitter/receiver module 406 receives audio signals from the PLC 400 as determined by the earplug program 402 and transmits them as wireless signals 302 to the wireless earplug 100 (shown in FIGS. 1-3).

Referring next to FIG. 5, a method for receiving a wireless earplug 100 audio alarm is shown. Shown are the alarm input step 500, the insert earplugs step 502, the alarm time step 504, the controller transmittal step 506, the wireless receiver/transmitter to speaker transmittal step 508, and the play alarm step 510.

During the initial alarm input step 500, the user interacts with the controller 304 (as shown in FIGS. 2-4) to input a future time for an alarm to be transmitted to the wireless earplug 100. The method then proceeds to the insert earplugs step 502.

The insert earplugs step 502 is shown following the alarm input step 500. During the insert earplugs step 502, the user inserts an earplug into each ear 118. The earplugs may both be wireless earplugs 100, or one earplug may be a wireless earplug 100 and the other a conventional earplug. The user now has hearing protection in both ears 118. The method then proceeds to the alarm time step 504.

The alarm time step 504 follows from the insert earplugs step 502. The alarm time step 504 is reached when the current time is equal to the alarm time set during the alarm input step 500. The method then proceeds to the controller transmittal step 506.

During the controller transmittal step 506, the controller 304 sends wireless signals 302 to the wireless receiver/transmitter module 114 (as shown in FIGS. 1-4). The method then proceeds to the wireless receiver/transmitter to speaker transmittal step 508.

The wireless receiver/transmitter to speaker transmittal step 508 follows the controller transmittal step 506. The wireless receiver/transmitter module 114 electrically transmits the wireless signals 302 received from the controller 304 to the speaker 110. The method then proceeds to the play alarm step 510.

During the play alarm step 510, the speaker 110 translates the audio signals into sounds and broadcasts them in to the sound canal. The user then hears the alarm.

Referring again to FIG. 5, a method for hearing an alarm while wearing earplugs for hearing protection is shown. There are many cases where it may be desired for the user to wear hearing protection, while still being able to hear certain sounds. One example of the method shown in FIG. 5 is wearing of hearing protection in a noisy environment in order to sleep, while still being able to hear a wake-up alarm.

As shown in FIG. 5, the first two steps in the method are to input an alarm time to the controller 304 and to insert at least one wireless earplug 100 into an ear 118. The other earplug may be a conventional earplug, a wireless earplug 100, or the user may choose to only wear the wireless earplug 100. The user may insert the wireless earplug 100 at any time prior to the alarm time.

During the alarm input step 500, the user may set parameters for the alarm, for example, volume, duration and type of sound. Default parameters may also be pre-set on the controller 304.

When the alarm time is reached, as in the alarm time step 504, the controller 304 sends the wireless signals 302 to the wireless earplug 100. The wireless signals 302 may be any sounds capable of being stored on the controller 304 and sent wirelessly to the wireless earplug 100, for example, a smartphone ringtone.

When the wireless receiver/transmitter module 114 receives the wireless signals 302, in the wireless receiver/transmitter to speaker transmittal step 508, the wireless receiver/transmitter module 114 electrically communicates the audio signal to the speaker 110.

Lastly, the speaker 110 receives the audio signal in the play alarm step 510, and the sound is played by the speaker 110. The user then hears the alarm. The alarm may be set to be a certain duration, or require the user to input a command to the controller 304 to cease the sound.

Many of the functional units described in this specification have been labeled as modules, in order to more particularly emphasize their implementation independence. For example, a module may be implemented as a hardware circuit comprising custom VLSI circuits or gate arrays, off-the-shelf semiconductors such as logic chips, transistors, or other discrete components. A module may also be implemented in programmable hardware devices such as field programmable gate arrays, programmable array logic, programmable logic devices or the like.

Modules may also be implemented in software for execution by various types of processors. An identified module of executable code may, for instance, comprise one or more physical or logical blocks of computer instructions that may, for instance, be organized as an object, procedure, or function. Nevertheless, the executables of an identified module need not be physically located together, but may comprise disparate instructions stored in different locations which, when joined logically together, comprise the module and achieve the stated purpose for the module.

Indeed, a module of executable code could be a single instruction, or many instructions, and may even be distributed over several different code segments, among different programs, and across several memory devices. Similarly, operational data may be identified and illustrated herein within modules, and may be embodied in any suitable form and organized within any suitable type of data structure. The operational data may be collected as a single data set, or may be distributed over different locations including over different storage devices, and may exist, at least partially, merely as electronic signals on a system or network.

While the invention herein disclosed has been described by means of specific embodiments, examples and applications thereof, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope of the invention set forth in the claims.
