Description

MICROPHONE WITH CANCELLATION OF NOISE, FOR USE WITH SUPPORT OR TO BE USED IN THE EAR FIELD OF THE INVENTION This invention relates to a handset. The handset allows the user to execute multiple media (multimedia) recognition and speech recognition applications for telephone, computer, telephone by computer or dictation and the like. Preferably, the handset is lightweight. The handset is preferably self-sustaining. Preferably, the handset contains at least one microphone element for canceling the background noise and at least one receiving element for transmitting audio signals to the user's ear or ear. The handset is capable of being used in the ear (left or right) of the user, without a headset. Preferably, the handset is capable of being attached to a support to allow "hands-free" and / or "wireless" access to communication systems, for example, the handset may be a "hands-free" handset. More particularly, the invention relates to a handset, preferably that REF: 24672 comprises a housing having at least one receiving element for its placement on the left or right ear canal of the user. The handset also comprises an ear strap structure, attached to the housing, preferably by a spring element. The ear strap structure is placed behind the ear and preferably has an arched shape. Preferably, the belt structure for the ear has a belt element for the ear movable in a lower portion, towards or at the opposite end of attachment to the housing. Preferably, the belt element for the movable ear has a drop shape, for placement behind the ear. The handset further comprises a rotating pole microphone that contains at least one, preferably two microphones to allow the voice of the user, preferably to transmit the voice substantially free of background noise. The ear loop structure is also preferably contoured and adapted for better contact with the surfaces behind the ear, for example, the ear loop structure may have the shape on each side which is adjusted in a manner substantially engageable with the surfaces behind the ear (e.g., to engage attachably behind the atrial portion, e.g., behind the fossa or propeller and / or the anti-helix, and / or over the mastoid bone that protrudes from the skull behind the ear, that is, behind the back of the ear and the skull). The ear strap member can also serve to hold the handset in the holder so that the handset acts as a microphone system for speech and for remote field sound recorded by the installation of a simple electronic switching element in the handset .

BACKGROUND OF THE INVENTION Some handsets of the prior art have included various intermediate support structures for holding the handset in cooperative relationship with the ear and with the mouth of the user. Such structures have included tiaras and elements for attachment to the lens frame. The handsets of the prior art suffer from several disadvantages. One of the problems of the handsets of the prior art relates to the headbands per se, which are necessary with most designs of handsets to provide the necessary support. The diadems are inherently bulky, are added to the cost of the handset and must be maintained and stored. For some applications such as, for example, when another heavy garment is to be worn on the head, the headbands are often uncomfortable or inadequate. further, for a large number of operators aware of their hair arrangement, headbands of any kind are problematic due to their volume and the tendency to tighten and alter the hair. The handsets have advanced from bulky and uncomfortable headsets which were attached to the skull, to miniature lightweight handsets which are fixed on the ear or on the lenses. In the state of the art, the transducers are placed in a housing which is fastened behind the ear, with tubes leading from the transducers to the mouth and to the auditory meatus of the operator. Alternatively, the housing is held in the frame bar of a head clip which resembles a frame similar to eyeglasses, with the same kind of tubes used to conduct the sound to and from the transducers. Other methods of avoiding handset support include suspending a set of a loop placed around the ear, similar to eyeglass frames, or suspending the eyeglass frame assembly itself. However, the eyeglass clasp method tends to deflect the optical axis and is limited in any case to people who wear glasses. The curl on the ear lacks stability and also alters the optical axis if lenses are also used. These structures have turned out to be problematic. In practice, the bracket for the head of the eyeglass frame is cumbersome and not flexible. The housing placed behind the ear tends to hang on the helix of the ear in an unpleasant manner and the tube that extends into the meatus is also irritating. In both cases, handsets must be manufactured for left and right ear models. Other elements to avoid the headband support therein are ear molds to hold the handset from the inside of the ear. This needs the adjustment of the ear mold to the individual users. Handsets without the headset have not been adopted in any extensive commercial practice due mainly to the fact that such headset handsets do not adapt to average ear variations and, therefore, do not fit closely or appropriately and easily fall out of the ear. ear. A growing concern of the comfort of the operators as well as the operation of the equipment has prompted recent efforts to improve the radio and telephone handsets. Broadly, the two main causes of discomfort in users are the heavy and bulky equipment, and the distribution of any weight that is involved. Significant reductions in weight and size are obtained by replacing the heavy magnetic core receivers and the carbon type transmitters with miniature balanced frame transducers of the type commonly used in hearing aid devices. These transducers have been used with acoustic feedback tubes, and this antecedent has also been used in the technique of telephone handsets in order to reduce weight. Another general problem of the above handsets involves the support of suspension mechanisms for positioning the handset according to the geometry of the user's mouth and ear. One aspect of this problem is that conventional brackets in the handset designs use very complicated and bulky fitting features. Simplified support designs have sacrificed at least to some extent the ability to adjust. In addition, the above support designs do not adequately take into account certain user preferences, particularly of the telephone operators, which include the positioning of the support pressure, the way the handset is placed and removed, and the movement of the transmitter. , regardless of the receiver. An additional problem of the above handsets, mainly acoustics but which are based in an important way on the comfort of the operator, is related to the seal of the receiver with the ear. Seals are desirable from the transmission point of view, but are obtained in current handsets with a considerable sacrifice in operator comfort. Therefore, the prior art has not provided an adjustable communication handset. The prior art has also not provided a computer handset that has good fidelity in both transmission and reception in a noisy environment and that is not annoying or obstructive when used as a constituent that causes little or no impediment or distraction to the user. More particularly, the prior art has not provided a relatively low-cost, lightweight handset that can be used in any user's ear, which uses at least one microphone, or a telephone handset which can be used as a remote, self-sustaining field microphone system that allows the user to use a "wireless" environment.

DETAILED DESCRIPTION Figure 1 illustrates the noise canceling handset 10, temporarily fixed to the stand or pedestal 40 according to a preferred embodiment of the present invention. The manner of carrying out this mechanical connection of the handset 10 and the support 40 will be described later. As shown therein and with reference to all of Figs. 1-10, the noise canceling handset 10 includes a unique arched housing 20, having acoustic port holes 22 which fit snugly over the ear. outside to carry sound directly to the ear, as shown in Figure 2A. The housing 20 is connected by a spring element 90 to an arched ribbon structure 30 for the ear, which preferably has an ear strap element 40 attached to the ear strap element 30. The spring element 90 is preferably covered with a sleeve (not shown) preferably made of a first molded plastic or of any other support structure to assist with a more rigid support between the belt structure 20 for the band and the housing 20. The ribbon structure 30 for the arched band is preferably contoured to reflect the shape of the back of the ear or of the mastoid bone protruding from the skull behind the ear., to rest comfortably on the upper part of the ear and the ear lobe for stability of the handset 10. The flexibility and shape of the structure 30 of the ear strap ensures a comfortable fit. In the preferred embodiment, the ear strap element 40 is attached to the ear strap structure 30 by a spherical ball joint element, which provides an adjustable element for securing the handset to any user's ear. Either the ear strap structure or the ear strap element may have a male member which is engageable in a female member of the other (and consequently any of the ear loop or element structure). of ear strap may have a female member which is engageable with the male member of the other), 30, to form the preferred seal. The pivotal connection, the ear strap member of the ear loop structure simultaneously serves at least two purposes, specifically ensuring a precise and firm fit of the handset to the wearer's ear and mechanically holding the handset in a support, as shown in figure 1, by a male member to a female coupling member, connection which will be described later. A rotary pole microphone device 50 extends obliquely from the housing 20 having a microphone cover (not shown) at the distal end. The cover houses at least one microphone element, which is preferably covered by a protective means, for example by a weather vane 60. The pole microphone device preferably has a second sleeve 51 covering a portion of the pole 50 device. The sleeve 51 is mounted inside the housing 20 to constitute the ball and joint or ball-and-socket element 55. The pole microphone device 50 is adapted to carry sound preferably from the plurality of microphones located on the cover at the distal end of the receiver or the transducer element (not shown) contained within the housing 20. In Figures 1 and 2 , the pole microphone device 50 rotatably connects the ball-and-socket joint member 55 so that the sleeve 51 has a male member, the sphere and the housing has a female member, the receptacle, - but so that Alternatively, the male member may protrude from the housing and the female member is positioned at the end of the sleeve. This seal member 55 allows the pole microphone device 50 to rotate to be placed behind the left ear or right ear of a user. Therefore, when the user uses the handset in the left ear with the pole microphone 50 positioned on the left side of the head, the user can easily rotate the pole microphone device 50 from 0 * to 180 'to be at a right angle to the head, if the user chooses to switch the handset to the right ear. Towards the end of the microphone, the pole microphone is preferably tilted approximately 15 * to 45 ', more preferably approximately 30 *. Therefore, the adjustment before use of the handset 10 consists in positioning the rotary pole microphone device 50 preferably at a distance of about 6.4 to 25.4 mm (0.25 to 1.25 inches), preferably to about 19 mm ( 0.75 inches) of the user's lips, as shown in Figure 2B. The arched band structure 30 for the ear is then placed behind the ear, by rotating the band member 40 for the preferred ear to be held against the inner portion of the earlobe. The housing 20 is placed on the outer ear of the user to ensure a comfortable fit. The spring element 90 allows the ear strap structure 30 to flexibly rotate approximately 360"around the axis of the housing 20. This flexibility provides the user with the ability to position the ear strap structure with the ear member. favorite ear strap behind the ear and to place the housing with the receiving element on the outer ear, as shown in figure 2D. Accordingly, the handset preferably has features that help to position the pole microphone device 50 in the proper position for reliable voice recognition, which includes: an adjustable ear strap element 40, for securing the handset to the user's ear for stability; and a rotating pole microphone device (see Figures 2A-2D). As shown in Figure 1, the electrical connection element 80 extends from the lower portion of the housing 20. The housing 20 secures the incoming microphone electrode wires (not shown) from the pole microphone device 50 with the output wires from at least one receiving element (not shown) to a cover 85 of in-line module. The signals are transmitted from the wiring 80 of the cable to the electronic circuits contained in the module 85 preferably to cancel or reduce the acoustic background noise. The handset 10 of the invention is preferably designed to be sensitive to a distant sound source, especially when used in the stand as a desktop microphone system for uses such as speech dictation. The arbitrary sound fields which emanate more than a few centimeters away from the microphone cancel substantially up to 30 db (3200%). This is obtained by the preferred noise cancellation circuits contained in the electrical connection cover or in the in-line module cover 85. In Figure 2A-2C, the single housing 20 is constituted by a flat surface 25 and a surface 25a with an arched shape. From the lower portion of the flat surface of the housing 20 there is provided a receptacle (not shown) for housing a sphere (not shown), wherein the receptacle is part of the sleeve 51 of a rotary pole microphone device 50 to allow rotation . Alternatively, as mentioned above, the housing 20 can accommodate the sphere (not shown) and the receptacle (not shown) and would be in the sleeve 51, which provides the same rotational rotation of the pole microphone device. This ball-and-socket joint element 55 allows the pole microphone device 50 to rotate 360 * around the axis of the receiver housing 20, although 280 'of rotation is illustrated in FIG. 2A. Similarly, the pole microphone device can rotate 360 * about the axis of the sleeve 51. The pole microphone 50 is capable of moving perpendicular to the axis of the receiving housing 20 at the point of the joint or joint element 55, or towards and from the user's mouth when the handset is used in the user's ear, as shown in Figure 2C. It will be apparent to those skilled in the art that a simple reversal of the relative positions of the various rotating parts, specifically the pole microphone, will produce a handset especially suitable for any ear. Preferably, the distance from the mouth to the microphone should be in the range of about 6 to about 25 mm (1 / 4-1.0 inches), preferably about 13-19 mm (1/2 to 3/4 inches) ) or less. The most preferred distance of the microphone cover (not shown) from the mouth of the user is from about 10 to 30, preferably about 20 mm to allow proper acoustic transmission. The microphone cover (not shown) preferably has a white color or another color coded therein. indicates the side of the microphone voice which must be adjusted to face the mouth directly. Talking close on the sleeve-vane that protects the microphone cover of the present invention is useful for precise operation. The preferred position of the pole microphone device 50, when used in the left ear is with the vane sleeve 60 pointing towards the face or placed in a substantially L-shaped formation, parallel to the floor (note that the angle mentioned above towards the microphone end of the pole microphone). Alternatively, when the handset is used in the right ear, the preferred position of the Pole microphone device 50 is with the vane sleeve 60 pointing towards the face or placed in an L-shaped formation parallel to the floor (note again the angle of the pole microphone end). Figure 2C shows the rotation of the rotary pole microphone 50 parallel to the axis of the housing 20 for use when it is preferably placed in the holder 40 (not shown) to obtain the optimum speech recognition at a distance. The preferred embodiment is when the handset is inserted into the holder 40, as shown in Figure 1. The preferred placement of the pole microphone device 50 when the vane sleeve 60 is placed upwards at 90 * parallel to the plane of the support 40, as shown in Figures 1 and 2C ( note again the tip inclination of the pole microphone). This placement allows the opposite side of the microphone to face the user which allows for remote field speech and sound recording to be transmitted to the preferred directional microphone that is located on the microphone cover below the sleeve-vane 60 , and preferably only one microphone is in operation due to a switching system element (not shown). Figures 3A and 3B show plan views comprising the components of the handset. The housing 20 has a right side 20a and a left side 20b which are shown in Figure 3B. In Figure 3A, the housing 20 is comprised of at least one receiving element 21, although more than one receiving element such as miniature electromagnetic "button" transducers of the type known for use in listening aids can be used. The receiver element 21 converts the received electrical signals from any "multimedia" multi-media system into sound waves that are to be transported directly to the entrance of the user's ear canal by a plurality of acoustic port holes 22 located on both sides of the receiver. accommodation. This further facilitates reversible listening of the handset when used in either ear. The port holes 22 in the housing cover the other ear which allows the audio sound to be transmitted directly to the channel transmitted from the user's ear without the need for an acoustic tube. Therefore, as a result the housing 20 has a preferred arcuate shaped surface 25a that fits the outer ear of the user, without a tubular conduit for transporting the sound from the receiver or the transducer to the user's ear canal. The housing 20 can be shaped as a circle, rectangular or any geometric shape which sufficiently covers the outer ear. The cable wiring 80 of the handset preferably extends from the lower portion of the arcuate surface 25a of the housing 20. Alternatively, the wire wiring 80 may pass through the spring element and extend from an opening or any portion thereof. of the structure 30 of the tape for the ear. The wire wiring 80 leads to an electronic housing or a module cover 85 in line to an adapter 95 having two poles or ends 96, 97, respectively, which are shown in Figure 3A. The 96 pole, the microphone socket shows the microphone icon and plugs into the "mic in" receiver (microphone input) of any computer sound card \ Electrode 97 shows the sound icon and plugs into the "Speaker" receiver of any computer sound card. A converter plug (not shown) plugs into the microphone socket 96 for compatibility with other cards of other media, for example SoundBlaster computer cards. The handset cable wiring 80 connects the handset 10 to an external communication equipment. After the adapter 95 is plugged into the appropriate female plugs, feature 100 of the switch in the handset allows the user to execute multimedia (multi-media) and speech recognition applications, telecommunicate from his home or office by means of a computer telephone and use voice instructions for interactive games. Accordingly, the adapter 95 has the ability to be plugged into any sound card or communication network, similar telephone systems, computers, speech recognition monitors or the like. The cover 85 of the in-line module has a switch function system 100. This switch function determines the double function of the microphones located on the cover below the sleeve-vane 60, which will be discussed later. The microphone electrode wires 77 extend from the microphone cover (not shown) through the pole device 50 to the housing 20, which is attached to the wires 76 of the transducer to constitute the wire wiring 80. The wire wiring 80 protrudes from the arcuate surface 25a of the housing 20. The wire wiring 80 hangs down and has its weight acting on the housing 20 to provide a clockwise torque. The torque torque provided counterclockwise, by the pole microphone device extending obliquely from the housing 20 and the retention action of the preferred tape member 40 for the ear attached to the structure 30 of tape for the ear serves to compensate for the torque in the clockwise direction and provide additional stability to hold the handset in place. The pole microphone device 50 extends from the ball-and-socket joint 55 mounted on the flat surface 25 of the housing 20. The arcuate band element 30 for the ear is constituted by a left element, a right element, a first end and a second extreme. The first end of the ear strap member 30 is mounted by a spring element 90 to the top of the flat surface 25 of the housing 20. The spring element 90 provides tolerance to the ear strap structure 30 with flexibility to move up or down relative to the housing 20. This flexibility of the handset adapts to different sizes and shapes of the ear, behind the earlobe and behind the atrium, (i.e., behind the fossa or helix) and / or anti-helix, and / or over the mastoid bone protruding from the skull behind the ear, ie, between the back of the ear and the skull) behind the ear or ear. The second end of the structure 30 of the ear strap is mounted by a ball joint element 45 on the ear strap element 40, preferably formed as a drop, as shown in FIGS. 3, although any geometric shape can be used. The ear strap element 40 has an upper surface, a lower surface, a left side and a right side. The upper surface of the ear strap member 40 is mounted on the ear strap structure 30 by the ball-and-socket joint 45. This ear strap member 40 allows the user to adjust the element 40 to the position suitable against the lower back portion of the ear for tightly securing the handset 10 to any size of the ear lobe. The rotatable adjustment of the ear strap element 40 is from 0 to 180 ° towards the axis parallel to the plane of the side of the wearer's head or towards or away from the lower portion of the ear lobe. This oscillation of the band of the ear strap is pivotal or rotatable so that an adjustment of the handset to the ear of the user is obtained, as shown in Figure 2C. In addition, the spring element 90 allows the ear strap element 30 to move up or down, or to the left or right for a proper fit. The ear piece comprises the ear strap structure 30 and the ear strap element 40 is designed primarily for use with only one ear, as shown in Figure 2B, for the right ear. In Figure 3A, the housing 20 is constituted by a left arched housing 20b and a right arched housing 20a having a raised portion projecting from the middle portion of each arcuate housing (25a, 25b) to form a bubble. At least one receiving element 21 in Figure 3 is housed below the bubble, which has acoustic port holes 22 on both sides of the bubble to provide reversible utilization. The wire wiring 80 also contains a clothespin assembly 110 or a line cable clip which allows the user to secure the wire wiring over any article of clothing for easy mobility without the impediment of having to be entangled with wires. The user is able to speak on the handset 10 without being physically connected to any communication element, or to a chirally hand-held handset. Figure 4 clearly illustrates the support 10 with a female member 15 projecting from the cavity of the support 40. The support 10 comprises a base 41, a vertical element 42, preferably conical in shape, although any geometric shape may be suitable, for example a square, rectangle, triangle or similar. The female member 15 such as the raised bolt engages in the coupling recess with the male member of the ear strap element 40, such as a bolt hole, in order to secure the handset 10 to the belt 40. This is carried out by the female member located on the lower surface of the ear strap element 40, the male member 15 which is inserted and engages with the female member of the ear strap element 40, as it is assembled in the ear. Figure 1. This coupling allows the handset 10 to be held in the holder 40. Alternatively, the ear strap member 40 may contain a male member, and the holder 40 may be constituted of a female member to obtain the same coupling of the handset to the support 40. Other suitable coupling elements for fixing the handset 10 to the support 40 can be a hook and curl element, i.e. Velero or similar. When the handset is coupled to the base, the handset functions as a self-sustaining desktop microphone system when the switch 100 which is also shown in Figure 6B, preferably has a green button, and moves to the "A" position. "(not shown). This position activates only the "mic" receiver. Preferably, the decoupling of one of the two microphones shown in Figure 5 so that the double function microphone offers a high-fidelity handset for speech dictation; a desktop microphone for remote field speech and sound recording, - and most commonly used applications of speech and impulse or precise activation with speech. Figure 4B shows a side view of the support 40, in which the female member 15 extends vertically within a curved outer portion of the support 40 or cavity 12 as shown further in Figure 4C. The cavity 12 provides additional mechanical interlocking stability for the preferred ear strap member 40 to fit tightly into the holder 40. Various materials can be used to produce the housing 20, the ear strap structure 30, the element 40 of tape for the ear, the pole microphone device 50, the cover for the microphone, the support 10 among the various resins and synthetic plastics. The preferred plastic molding material of these components is made of type V ABS, per L-p-ll83 which has been found to be quite satisfactory from the point of view of weight, appearance, comfort and workability. Figure 5 illustrates the wiring diagram for noise cancellation housed within the in-line module 85, preferably to reduce and cancel the background noise. As shown herein, the handset 10 generally includes at least one microphone element, preferably a first microphone and a second microphone 52 and 54, respectively, and a speaker element or receiver element 22, as shown in FIG. Figure 5. Each of these components (52, 54, 22) has a positive and negative cable that connects to the in-line module 85, which then takes the signal from the microphones and the audio signal to be transmitted from the loudspeaker element and transmits the signals through the wire wires 80 to the adapter 95, which carries the connections 76-77 to external communication systems, for example, multi media (multimedia) applications and speech recognition, computer telephony. Preferably, the adapter plugs into sound cards in the back of a computer system. Figure 6A illustrates circuit board assembly 120 within in-line module cover 85, which is shown in Figures 3A-3B. The circuit board assembly 120 contains circuits which process the signals from the microphone element, preferably the first and second microphones 52 and 54, respectively, for delivery to the sound system of the receiver element 22. The circuit board assembly 120 is adapted to receive speech and background noise signals from the first microphone 52 and to subtract the background noise signal from the second microphone 54 so as to activate a signal which substantially represents speech . Such a signal is supplied to a transmission device (not shown) so as to convert it to an RF or IR signal and transmit it to a remote receiving device (not shown) by means of the adapter 95 in which the signal transmitted in the cable wiring 80 mainly comprises speech. The first and second preferred microphones 52 and 54, respectively, are preferably held in place by a support element (not shown) which, for example can be constructed of a foam-like material. Although in the above embodiments they have been preferably described in those in which there is only a first microphone 52 and a second microphone 54, the invention is not limited, and any number of microphones 52 can be used for the first microphone and / or the second microphone. The individual circuit components without reference designations shown in Figures 6A and 6B are connected as shown and will not be discussed further, since the members and values are obvious to those skilled in the art and are not necessary for an understanding of the present invention. Figure 7 shows a cross-sectional view of the left arched housing 20b comprising the housing 20. The description provided for the left arched housing 20b is the same as for the left arched housing 20a (not shown). As shown in this, the housing 20 generally includes the left arched housing 20b, the right arched housing 20a (not shown) as a first opening for receiving the spring element 91, a flat surface 25, a second opening which is the female receptacle for fixing the device 50 of the pole microphone by the spherical ball joint element 55 and a third opening 81 for the output cable wiring 80. The ball-and-socket joint element 55 rotatably connects the second end of the pole microphone device 50 to the housing 20. The first and second preferred microphones 52, 54 are placed at the distal end or at the first end of the device 50. of pole microphone covered by a preferred protective means, preferably a sleeve-vane 60 to protect against any possible overload of sound pressure. The acoustic port holes 22 are shown in the bubble area of the left arched housing 20b, with identical port holes and located in the bubble area of the right arched housing 20b for reversible use of the housing 20 in the right or left ear of the user . Figures 8A-8C illustrate different perspective views of the structure 30 of the tape for the arcuate band, preferably with an arched shape to fit the ear of the user when securely fastening itself to the atrium (e.g. , the fossa or the propeller and / or the antihelix and / or over the mastoid bone protruding from the skull in the back of the ear, that is, between the back of the ear and the skull) of the back of the the ear and toward the lower portion of the ear or the earlobe, preferably by the adjustable ear strap element 40. In Figure 8A, the arched shape of the member of the ear strap member 40 is shown. The inner surface section 30a of the ear strap element 30 follows the contour of the mastoid bone behind the ear or at the rear of the auricle and can be firmly attached to the mastoid bone behind the ear or to the back of the ear. the atrium. The preferred ear strap element 40 is attached to the lower portion of the earlobe to obtain the desired narrow fit in the ear. As a result, the outer surface of the section of the ear strap element 30 is urged closer against the back of the ear of the user, while simultaneously generating a more hermetic seal of the housing 20 covering the outer entrance of the ear canal. . This narrow adjustment provides stability so that the user can operate the handset without any hindrance or obstruction. In Figure 8B, the cover of the left side member and the cover of the right side member, 35a and 35b, respectively, are shown. Once the ball-and-socket joint element 45 of the preferred ear strap member 40 and the spring element 90 are placed on either side of the element 35a or the side element 35b and the remaining side is aligned, the covers 35a, 35b are preferably bonded together by welding. The tape element 45 for the ear must be free of any adhesive. Fig. 8C shows a cross-sectional view of the spherical ball point element 45 before fixing the components in place by fastening elements or by any other suitable fastening element. As shown herein, the ear strap member 40 is provided with a sphere (not shown) housed with a female plug 45 in the ear strap structure 30. Alternatively, the sphere of the joint member 45 may be part of an ear strap member 30, while the socket is located on the ear strap member 40 to obtain the same ball joint. for rotating or pivotal rotation. In figure 9, the interior components of the preferred embodiment, a noise-canceling handset, are shown without the outer structures, i.e., the housing 20 or the tape structure 30 for the ear. The loudspeaker or transducer element 200 is housed within the housing 20 (not shown). The pole microphone device 50 is shown and has at least one microphone element, preferably the first microphone 52 of a second microphone 54 placed therein in relatively close proximity to each other. The first preferred microphone and second microphone 52 and 54, respectively, are aligned side-by-side in the microphone cover 210, which is preferably covered by a protective element or preferably by the wind vane sleeve 60.

The microphone cover 210 in FIG. 9 is constituted by a top microphone cover 210a and a bottom cover 210b fixed by adhesive elements or preferably held together by sonic welding. The preferred microphone cover or the sleeve-vane 60 helps minimize acoustic distortions. The microphone cover 210, the loudspeaker 200, the module cover 85 in line with the circuit board assembly (not shown) the pole microphone device 50 has at least one microphone element, preferably the microphones 52 and 54 and the preferred sleeve-vane 60 from sub-assembly 240 in line. The first preferred microphone 52 includes a pressure sensitive surface 53 and the second preferred microphone 54 includes a second pressure sensitive surface 55. As set forth, the first and second microphones 52 and 54 are positioned so that the respective pressure sensitive surfaces 53 and 54 are substantially 180 degrees apart from each other. The preferred microphones 52 and 54 are additionally positioned to have a preferred structural baffle (not shown) between the microphones. Such a structural baffle may be constituted of a structural member adapted to provide an acoustic separation between the microphones. Alternatively, an acoustic deflection array can be used instead of a structural element. Such a deflector is adapted to minimize or prevent the user's speech from being received by the second preferred microphone 54. The first and second preferred microphones 52 and 54, respectively, which are preferably electret microphones or similar microphones. As a result of the arrangement of the first and second microphones as shown in Figure 9, the first microphone 52 receives both the speech from the transmitter and the acoustic background noise which is presented in the vicinity, and the second microphone 54 essentially receives only the same acoustic background noise which is received by the first microphone. The first microphone 52 is adapted to receive acoustic sound such as the speech of the user and convert the received acoustic speech into a signal corresponding to such speech. The first microphone 52 also receives background noise which may exist. As will be appreciated, the background noise is combined with the speech of the operator and, as such, the signal provided by the first microphone corresponds to both the user's speech and the background noise. On the other hand, the second microphone 54 is placed inside the pole microphone 50 so that it receives ly only the background noise.

As stated, these microphones can be placed or held in place or they can be fixed by a preferred fastener (not shown) which, for example can be constructed of a foam-like material and which, in turn, is fixed to the cover 210. The respective outputs of the first and second microphones 52 and 54 are placed through wires (77) to form the wire wiring 80, which is inserted into the cover 85 of electronic equipment, in which the assembly 120 of circuit board of figure 6 is contained therein. The circuit board assembly contains circuits used in the processing of acoustic signals as described. The cable of the in-line module cover 85 is then fed to an inner ring 95 to supply signals to and from the outside or the host equipment. The inner ring cable runs through channel 95 which has two female plugs 96 and 97 emerging from it. The first female plug 97 preferably has a sound icon on the outer surface and is inserted in the back of the sound card of a computer in the "speaker" receiver. The second socket 96 preferably has the icon of a microphone on its outer surface and is inserted into the "microphone insert" receiver.

Therefore, the noise canceling handset is compatible with larger sound cards in any computer system. The in-line module cover 85 is constituted by a left cover (not shown) and a right cover (not shown) which can be fixed together after the circuits are installed, for example, when being pressed together, adhered or soldiers. As discussed previously, the switch is housed in the in-line module cover 85. Preferably, a button is installed on the switch, which can be diverted to the left or to the right. For example, if the handset is attached to the stand, the switch can be diverted to the left to act as a desktop microphone system. Similarly, if the handset is used on the ear, the switch is diverted to the right so that it acts as an anti-noise handset to receive and transmit signals. The switch 100 allows the first and second preferred microphones located at the ends of the pole microphone of the handset 10 to act as near-field microphones when using posts on the ear. This allows background noise supplied to the first microphone is subtracted from the speech and noise signal supplied to the second microphone so that an electrical signal substantially represents the speech is transmitted to the intended receiver, telephone, computer recognition system voice or similar. When the handset is inserted into the holder or is not used in the ear of the user, the user diverts the switch 100 to the appropriate position, if there is more than one microphone element. Therefore, the first microphone is turned off and the second microphone functions as a standard or conventional bi-directional far-field microphone. It is the function of the switch 100 to choose the position of the first and second microphone and the function of the transmitted signal. As will be more fully described in the following, the circuit board 120 of FIG. 6 may contain additional circuit elements for processing the signals received from the first and second microphones and for amplifying signals for supply to the loudspeaker 200 in FIG. 9. Therefore, the present invention provides a computer handset assembly, anti-noise, which has no chirality. The handset of the present invention is adapted to reduce or eliminate background noise. The preferred embodiment uses a first and second microphones which act as a dipole array and which can be coupled by the manufacturer or can be tested after manufacture, so that they have a frequency response which is essentially flat over the range of anticipated operation. By placing the first and second microphones as previously described, a sound (in particular a background noise) that originates from a source which is located at a distance substantially greater than the distance between the microphones, allows the sound of such Sound source is received by both microphones simultaneously. As a result, there is no differential in the substantial phase between them. Furthermore, the present invention allows the amount of noise cancellation to be adjusted either during the manufacture of the present pole handset assembly or alternatively by an operator using such a mount. The noise canceling handset, for example, of Figures 1-10, can be based on the principles governing the directivity patterns of omnidirectional microphones in near and far fields and the correct placement of pressure sensitive surfaces. of the microphone. The physical design of the microphone as shown in Figure 9 is the determining factor in the increase of S / N. Examination of these drawings shows that the pressure sensitive surfaces of the microphone are preferably placed at 180 mechanical degrees to each other and provide the optimum separation of the signal traveling to the voice microphone and the noise microphone in the near field . This separation is a primary component in the determination of the signal in the S / N ratio. The present invention can be used with the noise cancellation system and the circuits as described in the North American patent No. 5, 381,473 and the application continuation in part 08 / 339,126 filed on November 14, 1994, both of which have a common transferee with respect to the present application, and which are hereby incorporated by reference; however, they are not considered as necessary for the invention. The pole microphone handset device of the invention (eg, Figures 1-10) can provide speech recognition by computer. The pole microphone handset provides superior rejection of unwanted background noise and excellent voice response. The pole microphone handset can be configured to be compatible with all IBM and SoundBlasterTM audio cards. For compatibility with SoundBlaster, a converter plug (not shown) is plugged into the microphone jack 97. All other audio card interfaces can also be easily adapted as a result of the versatile adapter 95 shown in FIG. 10. FIG. 10 illustrates sub-assembly 275 of the pole telephone. As shown herein, such a pole microphone assembly 275 generally includes an electronic connection element 85, an adapter 95 for connection to an external communication system, electronic wiring 83 for the receiver element, a device 50 of the device 50 of Pole microphone having at least microphone elements arranged as previously described. Such a pole microphone device 50 preferably includes first and second microphones 252 and 254 which are positioned in a manner as previously described with reference to FIG. 9. In addition, such a pole microphone assembly 440 includes a cover 210a of upper microphone, a lower microphone 210b, and at least microphones, preferably first and second microphones 50 and 54, and a preferred sleeve-vane 60 as described in Figure 9. Preferably, the handset is connected to a microphone. cable, preferably of a length of approximately 2 meters, which ends in a 3.5 mm miniature plug or adapter 95. To connect the adapter 95 to the sound card of any computer, the user simply inserts the miniature plug 95 into the microphone input jack of the sound card (not shown).

As used with the SoundBlasterTM, it is important to turn off the automatic gain control (AGC) in the sound card before using the present invention in noise cancellation applications. If AGC is on, it will eliminate the noise canceling properties of the microphone by automatically increasing the input audio volume when the user is not speaking. AGC must be inactivated on SoundBlaster cards "" 1 on SoundBlaster cards "" when running a Creative MixerMR and pressing on the control of programming elements (software) of AGC under record setting ... ". The input audio gain is easily adapted to the target application using the Creative Mixer ™ program.

Microphone handset tests of the invention can be easily performed by using recording and playback features of a program of Creative Labs ave StudioMR.

With the present invention, voice recognition is no longer confined to offices with closed and silent doors, but can be used in noisy real-world environments, such as hotel receptions, hospital emergency rooms, manufacturing facilities and areas noisy office Therefore, handset microphone pointer interfaces and with computers, telephones or other multimedia equipment in the real world or, with a pole microphone device, can be used in various voice recognition applications. The present invention is not limited in this way and can be used with many other proposed uses such as voice dictation, home-to-office telecommunications by computer telephony, and instructions by use of voice for interaction games and so on. In addition, the invention can be used in speech recognition and / or verification systems such as systems for access to physical facilities, computer programs, computers or automatic talking machines and the like. The noise-canceling handsets described in the above are simple in construction, light in weight and easily adjustable, allowing them to be used with maximum convenience and with minimal discomfort and fatigue. Therefore, it is noted that the present invention provides an ergonomically designed, lightweight handset, which is fully adjustable.
