## Background
CROSS REFERENCE
This application claims priority from provisional application Ser. No. 61/573,866, filed Sep. 13, 2011, titled “Apparatus and Method for a Wireless Extension Collar for Use with Mobile and Fixed Wireless Devices” of Tara Chand Singhal. The application Ser. No. 61/573,866 is incorporated herein by reference.


FIELD OF THE INVENTION
Apparatus and method for a wireless extension collar device that is worn around a human neck in lieu of earphones and headphones, as a wireless extension of an end-user wireless device such as, a smart phone, a home and automobile-based device, and a command and control device, are described.
BACKGROUND
Headphones are used for private listening such as for music. They are also used for private communication as in telephone communication. These types of headphones are worn over the head. Office secretaries and order taking clerks use such headphone in a business environment.
A single ear piece that is plugged in the ear canal is also used in applications that include portable MP3 music playing devices. Bluetooth ear pieces are also plugged in the ear canal to communicate with a smart phone that is positioned in the vicinity of a person for hands free operation of the smart phones.
Use of such headphones, earphones, and Bluetooth® ear pieces make them uncomfortable for extended wearing as they are required to be plugged into the ear canal or cupped over the entire ear. This mode of use makes them both unsightly and uncomfortable to wear or use. They affect normal hearing while worn as they are intended to cut out ambient noise from the environment.
In communication devices, such as cell phones, the Bluetooth version of the earpiece that has become very popular lately to provide a hands free cell phone operation, also directs RF radiation in close vicinity to the brain.
Therefore, it is an objective of the embodiments herein to have headphone, earphones, and Bluetooth earphones that do not have the drawbacks of the prior art as summarized above. Yet another objective is to have more versatile and user-friendly music listening and wireless communication and command and control devices to work in conjunction with such end-user devices.
SUMMARY
The embodiments described herein use directional speakers and microphones in a collar worn around the human neck. Prior art related to directional speaker technology is illustrated with reference to FIG. 1. In this technology, an ultrasonic frequency carrier is used to radiate a directional ultrasound beam. The ultrasound beam signal is used as a carrier that is modulated with an audio signal. When the ultrasound beam is directed towards a human that is within the beam, only that human as a listener can hear the audio signal. Directional speakers based on this technology enable a highly directive audio signal to be radiated so that it can be targeted to an individual in a crowd.
This technology on directional speakers using ultrasound carrier waves was perfected by Dr. Joseph Pompei of Massachusetts Institute of Technology in the 1990's. Dr. Joseph Pompei founded a company named Holosonic Research Lab Inc., based in Watertown, Mass., USA that makes directional speakers based on this technology. Directional speakers are made in different sizes as provided on the company's website and the literature therein for different applications. Other companies such as American Technology Corporation also manufacture and market directional speakers.
See attached IDS form 8b that identifies and attaches literature from the Holosonic company website. As described on the website, the directional speakers based on this technology are being used in many applications, the chief application among them being for advertisement.
The embodiments described herein make use of such technology of directional speakers for a different application, that of a headphone. In the embodiments herein, a half-collar designed to be worn around a neck of a human, has two end-members where two directional speakers and microphones are placed that may radiate an audio signal directly towards the human ear without the need to wear a headphone over the ear or plug an ear piece in the ear canal. Thus, the embodiments herein are intended to and can be used in lieu of a headphone, ear piece, and Bluetooth ear piece, and it is believed provide many advantages over the prior art headphones and earpieces.
The benefits of such embodiments are that there is no ear plug in the ear and a headphone is not used over the head. That is, the embodiments herein provide a head free as well as a hands free operation. Since nothing is plugged in the ear canal or cupped over the ears, normal hearing is not affected. Hence, such a collar of the embodiments described herein may be worn for a better part of the day and used for a variety of applications including communication with and command and control of many end-user devices.
The collar may have a joint at the back that makes it easy to remove and put on around the human neck. The collar shape is angled vertically at back and changes to flat shape on the collarbone area enabling the two end-members of the collar with the directional speakers to lie flat on the collarbone area. The collar can be worn on top of clothing or under light clothing. Such a collar is not likely to affect wearing of jewelry, such as, either earrings or necklaces.
The collar is light-weight and may be on the order of a few ounces. The weight of the collar is distributed on the neck and the collarbone area. The collar is made of material that may come into contact with the body and may be made of a smooth material.
The directional speakers enable only the wearer to hear the audio. There are two built-in microphones for better sound pick-up along with the two directional speakers. The collar may have two independent audio systems, one each in each end-member of the collar, that can be used individually as either left or right side or both with a stereo effect based upon a user's preference.
The collar worn around the neck creates a distance between the collar antenna and the brain and thus keeps radiation away from the brain as compared to the Bluetooth ear pieces that are commonly used with smart phones.
These and other aspects of the embodiments herein are described and would become more clear with the help of the accompanying drawings and the accompanying description.

FIG. 4B illustrates the voice control commands via the collar 10 for use with end-user devices.
As illustrated in FIG. 5A, the wireless extension collar 10 may be used by a human 50 in different applications with different end-user devices. As illustrated in FIG. 5B, the collar 10 may work with many types of end-user devices that have their own voice control logic.
The collar 10 of the embodiments herein may be used in lieu of headphones, an earpiece, a Bluetooth earpiece, to wirelessly interface and connect to a variety of end-user devices that may include handheld, portable, fixed music systems, or audio-visual devices to hear music and audio. The collar 10 may also be used to communicate with these end-user devices to control their operation, where the collar 10 being worn around the neck provides for hands and head free operation. These and other features are illustrated where the headings are provided for reader convenience.
Wireless Extension Collar 10
As illustrated in FIG. 2A, the collar 10 has body 12 that may have join members 12A1 and 12A2 joined together by a joint 22. The body 12 has end-members 12B1 and 12B2 that house the directional speakers 14 along with battery 20, microphone 18, antenna 16, logic circuit 30 and controls 32. Each of the directional speakers 14 has a tilt mechanism 40 to fine tune the direction of the directional speakers toward the human ears.
As illustrated in FIG. 2A, the dimensions of the collar 10 are such that it when worn around the neck may have a width 36 of approximately 8 to 10 inches and a depth 38 of approximately 4 to 5 inches. Each end-member housing 12B1 and 12B2 has a width 34 of approximately two inches in diameter. These are notional size dimensions to illustrate the embodiments of the collar 10.
The housing 12B1 houses, directional speaker 14, control logic 30, user accessible controls 32, and microphone 18. The housing 12B1 is designed to lie flat on the collarbone and the joining member 12A1 is designed to be around the neck. The joining member 12A1 and the housing 12B1 may be made of material that is flexible and skin smooth.
FIG. 2B illustrates an elevation view and illustrates housing 12B1, joining member 12A1 joined with the help of hinge joint 24. A joint 22 joins the left and right side of the collar 10. The housing 12B1 may be approximately 1⁄4′′ inch high and it may be little less or a little more. The size of the housing 12B1 may be about a couple of inches. These are notional dimensions to illustrate the features of the collar 10 for making it suitable for wearing around the neck.
As illustrated in FIG. 2C, such a size of the collar provides for the collar 10 to be worn around the neck where the members 12B1 and 12B2 with the directional speakers 14 are positioned on the right and left collarbone areas 54A and 54B respectively of the human.
Use of Wireless Extension Collar 10 Around a Human Head 50
As illustrated in FIG. 2C, the collar 10 is shown placed around the human head 50 near the neck 58. The end-members 12B1 and 12B2 with directional speakers 14 of the collar 10 are positioned on the collarbone areas 54A and 54B. The collar 10 with the antenna 16 wirelessly communicates with an end-user handheld communication device 52 or a desk based communication device 52A.
The directional speakers 14 generate beams 56A and 56B directed towards the left and right ears respectively of the head 50. The diagonal distance 60 of the directional speaker 14 from the ear is estimated to be seven inches, the width of the ear 62 is estimated to be three inches, and the width of the beam 74 from the directional speaker to the human ear is estimated to be approximately 10 degrees to cover the human ear width 62.
It is believed that the movement of the head side ways or up and down within limits is not likely to affect the operation of the collar 10. As a simplified illustration, if the head is moved left or right as much as 45 degrees a minor change in the relative position and angle of the ears to the directional speakers is not likely to affect the operation of the collar. Similarly, if the head is tilted up or down from the straight position a minor change in relative position and angle of the ears to the directional speakers is not likely to affect the operation of the collar.
As illustrated in FIG. 3A, the directional speaker 14 has an ultrasound frequency signal generator 64, a modulator 70 and an audio logic 66 which produces the audio signal 68. The modulator 70 modulates the ultra sonic frequency carrier with the audio signal and feeds the modulated signal to a radiator 72. The radiator 72 may be in the form of a disk that radiates the ultrasonic signal based on the Piezo electric effect. The radiator 72 has tilt mechanism 78 that can be used to fine tune the tilt angle 76 of the radiator 72 to tilt the radiated beam 56A, with beam width 74, towards the center of the ear of the human head 50.
As illustrated in FIG. 3B, the end-members 12B1 and 12B2 house the directional speakers 14 and the associated collar functions. What are shown are user controls 32, collar logic 30, voice control logic 82, audio logic 66, Bluetooth interface logic 31, battery 20, microphone 18, and antenna 16. There may be memory and storage elements (not shown) as part of the collar functions that may be used to store programs and parameters relevant to the operation of the collar 10. There may also be external interface connector (not shown) that may be used to initialize, load and update new programs and parameters in the control logic.
Also shown are the elements of a directional speaker to include ultrasound frequency generator 64, modulator 70, radiator 72 and radiator direction adjustment mechanism 78. The tilt or direction adjustment mechanism 78 may use prior art arrangement of screws at 90 degree angle to each other.
There may be different embodiments, where the end-members 12B1 and 12B2 house the duplicate and mirror image of the entire system of FIG. 3B. Alternatively, the speaker elements, except the radiator element, may be housed in one end-member 12B2 and the collar logic and functions may be housed in the end-member 12B1. The radiator element 72 with the adjust mechanism 78 will be housed in both end-members 12B1 and 12B2.
The battery 20, antenna 16 and microphone 18 may also be housed in both housings 12B1 and 12B2. There may be other arrangements for housing the collar functions and the speaker functions and they are not ruled out.
Directional Speaker 14
Based on information obtained from the Holosonic Research Lab Inc., Watertown, Mass., the technology behind the directional speakers may be miniaturized and made in the form-factor that would be suitable for cell phones. The ultrasonic radiator uses piezo-electric technology and is in the form of a thin surface or membrane.
Therefore, it is believed, that a directional speaker along with associated electronics for use in collar 10 may be made in the form-factor of approximately two inches in diameter and approximately a quarter of an inch high. These dimensions may be a little less or little more and are notional dimensions for the specific use in the collar 10. The weight of the directional speaker along with the associated electronics in an end-member 12B1 or 12B2 may be of the order of a few ounces, making the weight of the collar 10 around a few ounces.
Therefore, the directional speaker 14 may be designed and manufactured in a form-factor suitable for the collar 10 application as has been described above. The radiator is based on the piezo effect and may be a few millimeters thick and around a few inches in diameter. The width of the ultrasonic beam emanating from the directional speaker is based on the size of the radiator. The energy of the beam is based on the energy in the ultrasonic frequency radiation. The power of the ultrasound energy in the beam determines the useful distance the beam can be projected.
Based on the specific application in the collar 10, the range of the directional speaker would be limited to a distance between the position of the directional speaker on the collar, which is worn around the human neck and the relative position of the human ear from the directional speaker on the collar. This distance is estimated to be around seven inches or so and may different for people with different physiques.
Based on data from Audio Spot Light® AS-16 Technical Specification of Holosonic Research Lab Inc., a speaker surface size of 15.75′′ square or about 245 sq. inch has listed a max power of 25 watts. Another Audio Spot Light® AS-24 with a speaker surface of 24 inches square has a listed maximum power of 65 watts. These are square dimensions but can also be circular dimensions as the speakers may be made in a disk form of various sizes.
From the information in the Audio Spotlight data sheet, Audio Spot Light systems are much less sensitive to listener distance than traditional loudspeakers. The optimum performance is attained at roughly 1-2 m (3-6 ft) from the speaker. Using this data as a guide, it is believed, the power needed for the ultrasound directional speaker as used in the collar 10 application would be around a couple of watts.
Based on prior art data on directional speakers from Holosonic Research Lab, the frequency of the ultrasonic wave may be of the order of 65 KHz and the audio signal that is modulated on this ultrasonic carrier wave may be 100 to 10 KHz making the collar suitable for most music listening in addition to audio speech listening.
Based on the information from Holosonic, the modulation that is used may be a proprietary modulation algorithm to minimize distortion in the audio and the audio is heard by the receiver or the human ear without any demodulation required.
The power of the audio signal that is modulated on the ultrasonic signal determines the volume of the audio signal, as the sound signal that is riding on the ultrasonic carrier wave is fed directly to the ear. Therefore the audio power requirements of the directional speakers as used in collar 10, it is believed, would be comparable to the power requirements of the prior art headphones.
It is believed, the desired audio power of the directional speakers based on similar headphone applications is likely to be of the order of tenth of a watt. It could be more or less but it is believed that a power output in the range of 100 Millie watts to 300 Millie watts would provide a required degree of audio volume control.
Considering the wattage, distance projection and speaker size of Audio Light Systems AS 16 of 25 watts, 6 feet of projection, with a radiator size of approximately 250 square inches, and scaling to the directional speakers as used in collar 10, it is believed, a speaker size of 2.25 square inches or a square of about 1.5 inch would be needed.
Hence the size of a directional speaker as used in collar 10, it is believed, would be about 1.5 inch square, a size suitable for placement in the end-members 12B1 and 12B2 of the collar 10. These are approximate and notional specifications to provide a perspective on the size and rating of the directional speakers and may be different than these based on actual use in the collar 10.
Microphones 18
Microphones are common in prior art and are used in a variety of applications that include headphones for secretaries, and Bluetooth earphones that work with cell phones and in cell phones themselves. Any of these microphones may be adapted for use in the wireless collar 10. No specific claim is made to microphone technology other than how they are used in the wireless collar 10.
Further, the collar 10 may have a single microphone or a dual microphone in each end-member of the collar 10. If dual microphones are used, they may be used as part of audio pick up technology to improve the quality of the audio pick up. These are considered prior art technologies and no specific claim is made for these microphones.
These microphones 18 in the collar 10 are positioned on the part of the collar, as illustrated, and thus would be in an optimum position to pick up human voice signals of the human wearing the collar 10 around the neck.
Antennas 16
There are two antennas in collar 10, one on each side of the collar and in each of the end-members. Alternatively, there may be a single antenna that traverses the entire length of the collar including inside the join members 12A1 and 12A2, behind the neck. The antennas may be positioned in a better part of the collar including the end-members and the joint member around the neck. Both of these antennas arrangements may be used for reception and transmission of RF signals between the wireless collar and the other end-user wireless devices.
A position of the antenna below the neck on the collarbone areas keeps the transmitted radiation away from the head area relative to Bluetooth ear pieces and cell phones held next to the head. That is, in the collar 10, there is approximately eight inches of physical separation from the antenna location to the physical location of the brain of a human wearing the collar.
Optionally and alternatively, one antenna may be used exclusively for transmission and one used for reception. To further alleviate this type of concern related to radiation, optionally the transmitting antenna may be made a directional antenna that directs the transmitted radiation to areas away from the head. The technology of directional antennas is prior art and no specific claim is made to such technology except how it is used in the collar 10.
As illustrated in FIG. 3C, a perspective view 84 and a side view 86 of the antenna 16 are shown that provides for such a directional transmitting antenna in the collar 10. The antenna in the form of a wire 76 may be placed inside or surrounded by a shield 78 with a radiation arc 79 that radiates in all the direction except an arc 80 for the head area of a user wearing the collar.
That is, the shield 78 may have a parabolic shape opening of approximately around 145 degrees and thus keep radiation away from a 225 degree angle that would keep radiation away from the head area. Such a directional transmitting antenna may be positioned on the better part of the length of collar 10 so that the no matter how the human is positioned relative to the other end-user wireless device, the communication between the collar 10 and the other end-user wireless device would not be hindered.
FIG. 3C illustrates the concept of such a directional antenna with a reflector or a shield 78 that keeps transmitted radiation away from the head area. The radiation can still spread and reach the end-user wireless devices that are paired with the wireless collar 10.
Any Bluetooth spectrum that is suitable for such personal wireless device may be used. Bluetooth protocols provide for pairing and security between two Bluetooth equipped devices. Such prior art technology may be used and would be equally applicable to the collar 10.
Voice Command Control
As illustrated in FIG. 4A, the collar 10 functions may be operated with a voice command. The voice control of the collar may be activated and work in conjunction with manual controls 32 on the collar as shown in FIG. 2A. As a simplified illustration, the manual controls 32 may be used to turn on and off the voice command features of the collar 10. The voice commands 80 for controlling the operation of the collar 10 may include, on/off, standby modes, left, right or stereo modes and volume control for either the left or right or both the directional speakers. There may be other voice commands that are not ruled out. Collar voice control logic 82 receives the voice commands 80 and outputs the control commands to the collar control logic 84.
As illustrated in FIG. 4B, a set of voice control commands 86 may be used to control the functions of the end-user device 52. These voice commands may include on/off, standby modes, volume up/down, play/pause, fast forward/rewind, and operation mode depending upon the end-user device. These commands are received by the logic 88 in the collar 10 and forwarded via the collar 10 to the end-user device 52. It is assumed that the end-user device 52 is equipped with a voice command control function 90.
As illustrated in FIG. 5A, the collar 10 working around the human head 50 may be used to receive audio from, and control, end-user devices such as a TV 94, cell phone 52, desk phone 52A, music system 96 or portable music device 92, assuming such devices provide features for voice control and are equipped with a wireless function to connect to the wireless collar 10.
As illustrated in FIG. 5B, the end-user device 52 would have a corresponding Bluetooth interface for pairing with the collar device 10 and would have voice control logic 90 that provides for functions that include, control of device status from on/off and standby, receive command, implement command, collect status, and send status.
