Description:
CROSS REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application is related to, and claims the benefit of, U.S. Provisional Application No. 62/146,647, filed Apr. 13, 2015. The above-identified priority patent application is incorporated herein by reference in its entirety. 
     
    
     FIELD 
       [0002]    The present technology relates to a wireless, small, ergonomically designed, voice transmitting and attenuating device for fitting over a user&#39;s mouth. The device contains a microphone, two radios for simultaneously transmitting a user&#39;s voice to an earphone and to a communication device and a voice signal enhancement circuit for improving the communication signal. The structural design minimizes the escape of any sound from the device to the outside environment and reduces or minimizes the amount of ambient sound that reaches the microphones, thereby providing very clear, high fidelity voice transmission which can then be recorded. 
       BACKGROUND 
       [0003]    Various devices have been developed for damping and recording voice sound waves. For example, U.S. Pat. No. 3,114,802 discloses an early design that essentially provides a cup-like structure for fitting over the user&#39;s mouth, with a microphone housed therein. 
         [0004]    Similar devices have been used by court reporters. One such acoustic mask is disclosed in U.S. Pat. No. 3,193,624. This device has a cylindrical outer casing and a separate wall structure housed within the casing with a microphone mounted on this structure. The device includes a cylindrical air inhalation passageway extending outward from the face-masking structure for inhalation, with a diaphragm to restrict expulsion of air. One or more openings in the face-masking structure allow for exhaled air and sound to escape. The face-fitting part of the device is rubber and must be pressed to the user&#39;s face in order to reduce the amount of sound escaping to the ambient. The device is not designed to reduce leakage of ambient sound into the device, nor is it ergonomically designed. Further, there is no means for the user to hear the sound that they are producing in the device. 
         [0005]    Another acoustic mask is disclosed in U.S. Pat. No. 4,129,754. The device includes a barrel with a bell-shaped back, the latter preferably being set at an angle with respect to the barrel. A microphone is positioned at the end of the barrel remote from the bell-shaped back. The barrel portion and a portion of the bell-shaped back are lined with foam urethane to muffle noise and absorb moisture. The reporting device includes orifices located at the junction between the bell-shaped back (face piece) and the barrel for permitting pressurized air within the device to escape to the outside via an air communication channel from inside the device to the outside. Again, the face piece is a soft pliable material that requires it be pressed against the user&#39;s face in order to reduce escape of the user&#39;s voice from within the device. Further, there is no means for the user to hear the sound that they are producing in the device. 
         [0006]    In a related technology, U.S. Pat. No. 6,121,881 discloses a protective mask communication device including a housing constructed to be mounted on a protective mask. A microphone is located within the housing. The mask is contemplated to be a safety mask, such as that worn by firefighters. No attempts are made to restrict escape of sound into the ambient atmosphere or reduce ambient sound. 
         [0007]    U.S. Pat. No. 8,243,944 discloses a handheld foldable voice-muffling device using passive noise damping materials to decrease noise and a single microphonic transceiver to transmit a user&#39;s speech and receive incoming signals allowing him to wirelessly communicate with another person or other communication devices. The deformable materials used in the device do not adequately muffle the sound of the user nor ambient sound. Further, the device must be pressed to the user&#39;s face in order for the deformable material to form to the user&#39;s face. This is uncomfortable for the user, but is necessary to reduce the escape of sound between the face piece and the user&#39;s face. The device is not designed to record sound with the microphone and transmit the sound simultaneously to each of an ear piece and a phone. This makes communication difficult as the user is not experiencing the normal sounds that one experiences during a conversation. 
         [0008]    There is a need for a small voice attenuating device that provides very clear, high fidelity voice transmission simultaneously to both the user, by means of an ear piece, and to a wireless communication device such as a cell phone. Such a device would preferably overcome the challenges of recording or transmitting a user&#39;s voice while attenuating the sound of the user&#39;s voice. It would also preferably cancel or reduce ambient noise without the need for noise canceling microphones. 
       SUMMARY 
       [0009]    The present technology provides a small device for fitting generally over a user&#39;s mouth to provide very clear, high fidelity voice transmission. It functions as an intermediary between an ear piece and a cellular phone, computer or transmitter, by recording sound with the microphone and simultaneously transmitting the sound to each of the ear piece and the phone. This functional feature is achieved with a single microphone in communication with two radios positioned in specific orientations within the device. It overcomes the challenges of recording or transmitting a user&#39;s voice while attenuating the sound of the user&#39;s voice. It also cancels, minimizes or reduces any ambient noise without the need for noise canceling microphones. It provides the means to dictate without being overheard or to have confidential phone conversations in crowded environments such as restaurants. Both structural features and a voice signal enhancement circuit provide these advantages.

     DESCRIPTION 
       [0069]    In the context of the present technology, the term “fitting generally over a user&#39;s mouth” means that at least the user&#39;s mouth is covered, but can include, for example, but not limited to a user&#39;s mouth and nose, and a user&#39;s face. 
         [0070]    In the context of the present technology, the term “face-fitting” means fitting over the user&#39;s mouth, but may include a user&#39;s mouth and nose. 
         [0071]    In the context of the present technology, the term “dual double catenary” refers to a structure that has two inner catenaries and two outer catenaries, an inner catenary and an outer catenary forming a catenary pair, the two catenary pairs opposing one another to form a face piece to define an opening. 
         [0072]    In the context of the present technology, a radio receiving and/or transmitting short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz is referred to as a Bluetooth® radio. 
         [0073]    In the context of the present technology, a phone call or call is any sort of verbal communication over a wired or a processor controlled Bluetooth enabled communication device, such as, but not limited to a cellular phone, a laptop, a tablet, voice activated apps, recorders, transmitters, landline phones, computers or any device that uses speech and/or a microphone, including a telephone call, a Skype call and the like. 
         [0074]    In the context of the present technology, a phone is any sort of, processor controlled wired or Bluetooth enabled communication device, such as, but not limited to a cellular phone, a laptop, or a tablet computer, voice activated apps, recorders, transmitters, landline phones, computers or any device that uses speech and/or a microphone. 
         [0075]    Numerous features of the device were arrived at through testing and experimentation. These features, challenges and attributes that they impart on the technology are listed below, as follows: 
         [0076]    1. Two radios housed in the interior cavity of the device. Two Bluetooth radios are used to provide simultaneous wireless communication to an ear piece and a wireless communication device. The advantage of being able to do this is that it optimizes sound reconstruction for the user. Poor sound reconstruction or a lack of sound reconstruction is very distracting for a user. 
         [0077]    It was generally accepted by the industry that one cannot put two Bluetooth radios in close proximity because the signals will interfere with one another, causing noise, crosstalk and canceling each other out, or one may amplify the power going to the other antenna overloading the frontend. In fact, the manufacturer suggested that one cannot place two Bluetooth radios in close proximity, such as would occur in the device of the present technology. 
         [0078]    In order to overcome interference between the two simultaneous signals and to achieve the greatest efficiency, various orientations and distances were tested. It was found that the antennae of the radios should preferably have a linear horizontal center-to-center distance of not less than about 25 mm and not more than about 27.5 mm with a preferred distance of about 27 mm with a vertical offset of not less than about 3 mm and not more than about 4 mm. The radio antennae are best mirrored on a fiberglass-resin stack-up. The stack-up is preferably not less than about 1.57 mm thick and not more than about 3.7 mm thick, to provide the appropriate shielding and impedance. Using this configuration, simultaneous wireless transmission between the device and each of an ear piece in the user&#39;s ear and the wireless communication device (which is preferably a cellular phone) was achieved. 
         [0079]    2. Tapered air tube. The slim design that allows a user to easily slip the device into a pocket and to hold it comfortably in the hand results in a device with a small interior cavity. This limits the space for an air tube. The air tube is important for both air flow and for attenuation of sound emanating in the device. It was found that a wide tube allowed for sufficient air flow, but resulted in release of sound. A narrow tube reduced the air flow, but attenuated the sound better. An average adult speaking into the device is delivering about 1900 ml/second at peak air flow. 
         [0080]    It was found that the most efficient air flow and attenuation of sound could be obtained by tapering the air tube. A straight tube was found to have a set pressure release, therefore optimization of pressure release would necessitate customization of the exhaust tube to the user. It was also found that a tapered exhaust tube provided a variable pressure release which makes the device more suitable for use by a much broader range of people. 
         [0081]    3. Pressure buffer. While the tapered air tube provides good pressure control and sound attenuation, it was found that inclusion of a pressure buffer provided more even pressure control within the device and reduced both the intensity and number of pressure spikes. This makes the device more comfortable to use and helps to maintain voice transmission. Research has demonstrated that air pressure directly impacts sound attenuation. The greater the back or over pressure the greater the sound attenuation. However, user&#39;s have a limited tolerance for speaking in an over pressured environment. In fact, if the pressure is too high, the user may be unable to speak within that environment. 
         [0082]    4. Voice Signal Enhancement circuit (VSE circuit). In a small device that is pressurized, the noise to signal ratio is high. The usual approach to dealing with this is to use two microphones configured for noise cancellation. The VSE circuit was designed to overcome this requirement specifically in the voice sound range. The circuit creates a phase shift on the signal which is then added back into the original signal both widening the frequency and amplifying the frequency as the feedback loop nears its designed center frequency. This was found to increase the target frequencies and widen the other frequencies, making them more apparent and stronger. The VSE circuit therefore results in stronger and clearer signals and obviates the need for a second microphone. 
         [0083]    5. Dual double catenary face piece. This shape is best viewed in  FIGS. 12 and 20 . The face piece is the surface between each of the two dual catenary curves. Although pliable materials can be used to fit a wide range of face sizes and shapes, they must be pressed relatively hard against the user&#39;s face in order to form fit and significantly, in order to provide sufficient sound damping. Through testing on many user&#39;s, a dual double catenary shape was developed that fits a wide range of face sizes and shapes. As it fits a wide range of faces, it can be made of the same hard material as the remainder of the housing. This therefore provides better sound damping, both in terms of damping ambient sound and damping voice sound emanating from within the device. It is comfortable to use, as a user need not press to deform the face piece against the face in order for it to fit. 
         [0084]    6. Design of the housing. The housing allows for the user to speak downward into the device without the device having a right angled housing. This shape provides for a small, thin, ergonomic device that can be easily carried and stored by the user. 
         [0085]    Referring to  FIG. 1 , there is shown in general block diagram form, one embodiment of the technology. A body  10  houses a circuit board housing  12  with a circuit board  32  therein. The circuit board  32  is removable. The circuit board  32  has a processor  34  which is, without limitation, a microprocessor, and the following modules logically, electronically connected together: self-diagnostic and control module  30 ; audio capture module  33 ; power management module  36 ; listening output module  31 ; wireless radio  35 ; and data storage module  37 . 
         [0086]    As shown in  FIG. 2 , the physical attributes of the device  200  include an ergonomic design  38 , pressure management  39 , sound and noise silencing  40 , voice audio isolation  41  and air flow management  42 . In order to take advantage of advanced filtering, pressure management, and additional noise isolation, the processor  34  may handle floating point DSP (digital signal processing) algorithms. 
         [0087]    Audio Capture 
         [0088]    As shown in  FIG. 3 , the audio capture module  33  is logically controlled by the processor  34 . The audio capture module has one microphone  51  connected to Voice Signal Enhancement (VSETM) Circuitry  52 . The VSE circuitry allows the microphone to operate in a highly pressurized environment within the housing. The output from the VSE circuit  52  is received by an Analog-to-Digital (A/D) signal acquisition circuit  53  to acquire the voice signal which is subsequently processed by a stream processor  54 . 
         [0089]    The audio capture module  33  of the technology may or may not include a data encryption circuit  50  for enhanced security requirements. The data from the stream processor  54  and, optionally, the data encryption circuit  50  are received by a broadcast and recording processor  55 . The VSE circuitry  52 , A/D signal acquisition circuit  53 , the stream processor  54 , data encryption circuit  50  and broadcast and recording processor  55  are, without limitation, a part of the processor  34  rather than separate components. The processor  34  will, as directed by the user, determine if the data are to be recorded using a data storage module  57 , a recording or broadcast device, or other connection as would be known to one skilled in the art. The data are broadcast and processed using two wireless radios  35 , for example, but not limited to Bluetooth® modules/radios  35 , as shown in  FIG. 4A . 
         [0090]    Wireless Communications 
         [0091]    As shown in  FIG. 4A  the wireless radio  35  includes the broadcast and recording processor  55 . The broadcast and recording processor  55  receives audio stream data from the audio capture module  33  which is a direct feed through the data encryption circuit  50 . The broadcast and recording processor  55  controls the incoming and outgoing communications data streams by routing the data into or out of the communications interface  61  according to the settings retrieved from the configuration memory  62 . The communications interface  61  receives data from the broadcast and recording processor  55 . These data are converted to wireless audio for transmission. The configuration memory  62  stores the settings for all the wired and wireless communications in non-volatile storage and retrieval by the broadcast and recording processor  55  as needed. 
         [0092]    As shown in  FIG. 4B  the first wireless radio  35  communicates to a first wireless communication device, generally referred to as  60 , which in the preferred embodiment is a wireless earpiece  61  or a wireless headphone  63 . The other wireless radio  35  simultaneously communicates with any type of a second wireless communication device, generally referred to as  72 , for example, but not limited to a smart phone, a cell phone, a voice control system, a voice command system, a voice activation system, a voice authentication system, a voice recognition system, a dictation system, a second wireless earpiece  61  or a second wireless headphone  63  and a computer system. 
         [0093]    In another embodiment, shown in  FIG. 4C , the radios  35  have wired connections  56  that are used through a USB (Universal Serial Bus). In addition to communications, the USB connection  56  is the preferable method for charging the device. Both diagnostics and device updates are delivered through USB. 
         [0094]    In order to overcome interference between the two simultaneous signals and to achieve the greatest efficiency, specific selected proximity and orientations of the two transmitting antennae are used. The antennae are ceramic and have a frequency wavelength response of 31.25 mm when operating in the sub-¼ wavelength range. 
         [0095]    As shown in  FIG. 4D , the antennae  65  have a linear horizontal center-to-center distance of not less than about 25 mm and not more than about 27.5 mm with a preferred distance of about 27 mm with a vertical offset of not less than about 3 mm and not more than about 4 mm. They are mirrored on a fiberglass-resin stack-up  68 . The stack-up is preferably not less than about 1.57 mm thick and not more than about 3.7 mm thick. 
         [0096]    Listening Output 
         [0097]    As shown in  FIG. 5 , the listening output module  31  has a listening output processor  71  having input and output communications with the wireless radio  35 . The wireless radio  35  can be, for example, but not limited to, a Bluetooth module. The listening device can be, for example, but not limited to, a wireless earpiece  60 , or a wireless headphone  72 . In an alternative embodiment, the listening device can be a direct wired ear or headphone  63 . 
         [0098]    Power Management 
         [0099]    As shown in  FIG. 6 , the power management module  36  has a power source  80  which is, for example, but not limited to, one or more of a rechargeable DC battery  81 , a charge management module  82  or the USB connection  58 , which is connected and controllable by a power management processor  84 . The power management processor  84  configures power usage, configures or adjusts the charge management module  82 , and reports power and charge status back to the processor  34  which may or may not relay the information back to the user via an indicator  83 . If the power source  80  is a battery  81 , it can be recharged through the USB connection  58 . Alternatively, other contact or wireless charging methods, controlled by the charge management module  82  can be used to charge the battery. 
         [0100]    Data Storage 
         [0101]    As shown in  FIG. 7 , the data storage module  37  has a data storage processor  91  that controls the data in and out of the different storage devices including remote or plug-in storage  57 , USB connection  58 , and integrated data storage  92 . Non-limiting examples of storage devices include flash drives, thumb drives, micro-flash, trans-flash and USB drive storage devices. Through the USB connection  58 , a data stream can be, for example, but not limited to, transferred both by itself or recorded and transferred to a USB device such as, for example, but not limited to, a computer  90  or other suitable device. The data storage module  37  can also store configuration settings  62 . 
         [0102]    Diagnostics and Control 
         [0103]    As shown in  FIG. 8 , the self-diagnostic and control module  30  contains both software and hardware to test and assess the state of the device. The self-diagnostic and control hardware  100  interfaces with the processor  34  to send and accept data related to system analysis and reporting. The processor  34  is, for example, but not limited to, controlled through an interface and controller  101 , which is, for example, but not limited to a touch screen interface, a capacitive touch interface, a gesture interface, or a remote application that returns the result information and sends commands to the self-diagnostic and control hardware  100 . 
         [0104]    The Device 
         [0105]      FIG. 9  shows the audio capture and transmission device, generally referred to as  200 . A housing, generally referred to as  203  has an angled, curved back  201  and a generally planar base  206  to create a wedge shape terminating in a distal end  205 , a face piece  202  proximally and an access hatch  204  to a compartment in the rear of the housing  203 . The access hatch  204  is for access to the battery or assembly. The housing  203  has an ergonomic shape to fit either hand. The housing  203  is adapted for the attachment of an elastic type strap to fit around the neck or head of the user to allow for hands-free use for those persons with certain physical disabilities or for those simply wishing to have both hands free. 
         [0106]    The face piece  202  is located around the proximal end  220  of the housing  203  and is proximal to it. The face piece  202  defines a proximal opening  224  and is face-engaging. The user presses their face into the face-fitting rim  215  of the face piece  202 , such that the face piece  202  abuts the chin, upper lip and cheeks of the user to form a seal against the face. The face piece is hard and made from the same material as the housing for example, but not limited to a molded or printed plastic polymer, preferably 4 mm to 5 mm hard acrylonitrile butadiene styrene (ABS) plastic polymer. This has a Shore D durometer rating of about 70 to about 85. The face piece  202  and housing  203  may alternatively be a single unit. Whether one unit or two, they can generally be referred to as a face-fitting rim  215 . In an alternative embodiment, the face piece  202  is pliable, and made from, for example, but not limited to, hypo-allergenic rubber or hypo-allergenic plastic polymer. As noted above, the shape of the opening  224  allows the face piece to accept a wide range of face sizes and shapes. In an alternative embodiment, the face piece  202  covers both the mouth and nose to prevent further leakage of voice sounds but still should provide a tight seal against the face. 
         [0107]    As shown in  FIG. 10 , the housing  203  includes a full color Liquid Crystal Display (LCD) touch screen interface  214  to allow the user to monitor various device functions and statuses. At least one exhaust or relief port  212  is located at or in the vicinity of the distal end  205 , and a first side  208  and a second side  210  have indents  209 . The housing  203  is preferably a molded or printed plastic polymer, preferably 4 mm to 5 mm hard acrylonitrile butadiene styrene (ABS) plastic polymer. This has a Shore D durometer rating of at least about 70 to at least about 85. The material used in the housing promotes sound attenuation. 
         [0108]    As shown in  FIG. 11 , an interior cavity  218  is defined by the housing  203 . The inner surface  219  of the housing  203  is shaped to encourage reflection of sound waves within the housing  203  and is preferably concave, and more preferably rounded. A pair of air tubes  248  are located in the interior cavity  218  with the microphone  51  located in the interior cavity  218  between the air tubes  248 . 
         [0109]    As shown in  FIG. 12 , the face-fitting rim  215  of the face piece  202  has a concave dual double catenary shape. This shape has been found to provide the best tight seal against the face to prevent or reduce or minimize sound escaping as well as being very comfortable for the user. The face piece  215  has a bore  216  in the body  217  that extends from the opening  224  to the interior cavity  218  of the housing  203 . 
         [0110]    As shown in  FIG. 13 , the proximal end  220  of the housing  203  defines an angle  228  with the base  206  of about 40 to about 70 degrees, more preferably about 45 to about 60 degrees and most preferably about 55 degrees. The angle  228  allows the device to be thin enough to fit in the pocket of a user, while providing superior sound pickup, and it creates, along with the taper of the device, a user friendly, natural position for the user to hold it in their hand, when in use. 
         [0111]    Also shown in  FIG. 13 , a sound damping material  233  may line much or all of the inner surface  219  of the housing  203 . This material  233  is about 1 mm to about 8 mm thick, preferably about 2 mm to about 6 mm thick and most preferably about 3 to about 5 mm thick. Preferably, the sound damping material is also a moisture absorbing material such as acoustic or open cell foam. It is removably attached to the inner surface  219  by closures such as Velcro®. The sound damping material  233  may cover the microphone  51  shown in  FIG. 14  and may substantially, but not completely, fill the interior cavity  218 . The attenuation can be changed by a textured surface, such as, but not limited to, dimpling, waves, and curves. 
         [0112]    As shown in  FIG. 14 , the microphone  51 , which is, for example, but not limited to, an electret microphone or a Micro-Electrical-Mechanical System microphone, is housed in the circuit board housing  12  on the inner surface  219  of the housing  203  in the vicinity of the proximal end  220 , preferably about 15 mm to about 35 mm from the proximal end  220 , more preferably about 20 mm to about 30 mm, and most preferably about 25 mm. These distances have been found to provide for superior sound pickup. The air tubes  248  are located adjacent the circuit board housing  12 . 
         [0113]    As shown in  FIG. 15  at least one exhaust or relief port  212  is located at the distal end  205  of the device  10 . The exhaust system, generally referred to as  240 , is comprised of at least one exhaust port  212  and at least one air tube  248  which may be connected directly to the exhaust port  212 , but preferably is attached to a pressure buffer  241 . If present, the pressure buffer  241  is connected to the exhaust port  212  at one end and to the air tube or tubes  248  at the other end. All are housed within the housing  203  and result in gaseous communication between the interior cavity  218  and an ambient environment. The air tube  248  extends from the pressure buffer  241  terminating proximally in the vicinity of the proximal end  220 . The air tube  248  is preferably tapered or funnel shaped. If so, for one air tube  248 , the air tube interior diameter is approximately 15 mm at the air tube proximal end  249 , more preferably 10 mm interior diameter at the air tube proximal end  249  and most preferably 12 mm in interior diameter at the air tube proximal end  249 . The air tube distal end  245  is approximately 8 mm in interior diameter, more preferably 5 mm interior diameter and most preferably 6 mm in interior diameter. The diameter is adjusted to provide the same air flow from the housing for two or more tubes as is provided by one tube. In all cases, the taper is approximately 9.4 degrees, more preferably 5.9 degrees and most preferably 7.04 degrees. Without being bound to theory, the placement and taper of the air tube  248  reduces any restriction of the user&#39;s breathing by reducing air pressure and optimizing air flow while reducing loss of sound. In alternative embodiments, the air tube  248  could be one or more of oblong in cross section, have a bulb in it, and be located proximate the side  210  or back  201 . 
         [0114]    Still referring to  FIG. 15 , in one embodiment, the pressure buffer  241  has baffles  243 . In another embodiment, shown in  FIG. 16 , the pressure buffer  241  is a convoluted passageway  253 . In yet another embodiment, the baffles are adjustable. There are one or more pressure buffers  241 . 
         [0115]    The details of the VSE circuitry with an electret microphone are shown in  FIG. 17 . An input from the microphone  301  includes the positive terminal  401  and the negative terminal  402 . The VSE circuit  52 , which is on a circuit board, has a capacitor  305  and a resistor  306  (with a fixed capacitance), that may or may not be variable and that includes resistance part A  302  and resistance part B  304 . An audio output  303  is connected to the VSE circuit. The resistor  306  is connected between the positive  401  and negative poles  402  of the electret microphone capsule (which corresponds to the drain and the source of the JFET). If the resistor  306  is variable, it allows for tuning and controlling the drain current characteristics of the JFET. 
         [0116]    A sound wave, composed of frequencies within the range of human hearing, of oscillating pressure (SPL—Sound Pressure Level), impacts the capacitive transducer/transduction film within an electret (or other) microphone capsule  51  causing a capacitive difference that drives the gate of the JFET (Junction Field Effect Transistor) inside (or external if one is not contained within) the microphone capsule. The VSE circuit with a variable resistor allows for: reducing the output noise voltage; increasing the gate cutoff voltage sensitivity; increasing the saturation sensitivity; and controlling the voltage gain output for specific SPL requirements. The variable aspect of the resistor may be needed to adjust to the non-defined acquisition circuit/devices admittance, reactance and impedance characteristics but requires a fixed and stable bias voltage within a narrow range. 
         [0117]    The circuit creates a phase shift on the signal which is then added back into the original signal both widening the frequency and amplifying the frequency as the feedback loop nears its designed center frequency. The VSE circuit should be as close to the input as possible, taking the input and output component and junction parameters into consideration. In the case of Micro-Electrical-Mechanical System (MEMS) sensors, additional elements need to be added to the circuit, as described below. 
         [0118]    The use of VSE for audio has little perceptible effect at lower end frequencies of the voice spectrum and a significant effect at the higher end of the voice spectrum. This widening and amplification is very beneficial for algorithms that key on the higher frequencies for information such as the Hidden Markov Model algorithm commonly used in speech recognition. 
         [0119]      FIG. 18  shows the VSE circuit for a Micro-Electrical-Mechanical System microphone. The circuit, which is a circuit board, generally referred to as  52  includes capacitors  501 ,  502 ,  503 , and resistor  504 . The input MEMS sensor  301  includes the positive output  401 , the negative output  402  and the signal or digital ground  403 . An audio output  303  is connected to the VSE circuit. A power bias supply  500  provides power to the circuit board  52  and MEMS sensor  301 . 
         [0120]    There are various ways in which the device  10  can be used. The device may be held in the hand to capture and attenuate an audio signal from an audio source. The audio signal travels to the device from the audio source. A user can hold the device away from their mouth to capture and attenuate the audio signal from the user&#39;s mouth. The voice sound waves travel from the user&#39;s mouth to the device. The preferred embodiment is shown in  FIG. 19 . The user holds the device to their face and uses the wireless earpiece. The voice sound waves are emanated within the device. An ambient noise (noise from outside of the device and other than the user&#39;s voice) is reduced or minimized by the device. One radio provides the earpiece with a signal so that the user hears the voice emanated within the device, and simultaneously, a cellular phone is provided with a signal from the other radio so that a recipient hears the voice emanated within the device. 
         [0121]    The details of the dual double catenary, generally referred to as  600 , are shown in  FIG. 20A, 20B, 20C, 20D, 20E and 20F . As shown in  FIG. 20A , a first curve  602  and a second curve  604  create a tensioned area  606  therebetween. A cross section, as shown in  FIG. 20B , shows the tensioned area  606  between the two curves  602 ,  604 . As shown in  FIG. 20C , a tensioned flap curve  608  is located between and created by a third curve  610  and a fourth curve  612 . A cross section, as shown in  FIG. 20D , shows the tensioned flap curve  608  between the two curves  610 ,  612 .  FIG. 20E  is a schematic demonstrating how the tensioned area  606  and tensioned flap curve  608  are created.  FIG. 20F  is the equation for a catenary. 
         [0122]    Details of the touch screen interface  214  are shown in  FIG. 21 . Incoming calls are displayed on an incoming call display  702  and can be answered and ended using screen controls  704 ,  706  while leaving the associated communication device, which may be a phone, in a pocket or purse, thus significantly reducing the SAR (Specific Absorbed Radiation) to the user to about 0.01% of the typical mobile phone. The screen also shows information on the battery charge level on a battery charge level indicator  708 , Bluetooth pairing connections, Bluetooth signal strength on a signal strength indicator  710 , whether wired or Bluetooth headphones are attached on an attachment indicator  712 , microphone volume level on a volume indicator  714  and a mute button  716  for the microphone. Calls may also be placed using the screen&#39;s outgoing call function on a keypad  718  which mimics that of the phone. The configuration memory  62  stores instructions for the processor  34  to effect these activities.
