DETAILED DESCRIPTION

Embodiments of the present invention disclose methods and/or apparatuses for providing a three-dimensional (“3D”) audio output and ultra-bass effects through a multiple auditory-pathway (“MAP”) earphone. MAP earphones can produce different types of audio output and the vibration output at the same time. When 2 auditory pathways receive different signals to the auditory receiving centers at the same time, the brain will create a sound illusion of a three-dimensional (“3D”) audio output with ultra-bass effects.


The purpose of the following detailed description is to provide an understanding of one or more embodiments of the present invention. Those of ordinary skills in the art will realize that the following detailed description is illustrative only and is not intended to be in any way limiting. Other embodiments will readily suggest themselves to such skilled persons having the benefit of this disclosure and/or description.


In the interest of clarity, not all features or routines of the implementations described herein are shown and described. It will, of course, be understood that in the development of any such actual implementation, numerous implementation-specific decisions may be made in order to achieve the developer's specific goals, such as compliance with application- and business-related constraints, and that these specific goals will vary from one implementation to another and from one developer to another. Moreover, it will be understood that such a development effort might be complex and time-consuming but would nevertheless be a routine undertaking of engineering for those of ordinary skills in the art having the benefit of embodiment(s) of this disclosure.


Various embodiments of the present invention illustrated in the drawings may not be drawn to scale. Rather, the dimensions of the various features may be expanded or reduced for clarity. In addition, some of the drawings may be simplified for clarity. Thus, the drawings may not depict all components of a given apparatus (e.g., device) or method. The same reference indicators will be used throughout the drawings and the following detailed description to refer to the same or like parts.


In accordance with the embodiment(s) of present invention, the components, process steps, and/or data structures described herein may be implemented using various types of operating systems, computing platforms, computer programs, and/or general-purpose machines. In addition, those of ordinary skills in the art will recognize that devices of a less general-purpose nature, such as hardware devices, field programmable gate arrays (FPGAs), application specific integrated circuits (ASICs), or the like, may also be used without departing from the scope and spirit of the inventive concepts disclosed herein. Where a method comprising a series of process steps is implemented by a computer or a machine and those process steps can be stored as a series of instructions readable by the machine, they may be stored on a tangible medium such as a computer memory device (e.g., ROM (Read Only Memory), PROM (Programmable Read Only Memory), EEPROM (Electrically Erasable Programmable Read Only Memory), FLASH Memory, Jump Drive, and the like), magnetic storage medium (e.g., tape, magnetic disk drive, and the like), optical storage medium (e.g., CD-ROM, DVD-ROM, paper card and paper tape, and the like) and other known types of program memory.


The term “system” or “device” is used generically herein to describe any number of components, elements, sub-systems, devices, packet switch elements, packet switches, access switches, routers, networks, computer and/or communication devices or mechanisms, or combinations of components thereof. The term “computer” includes a processor, memory, and buses capable of executing instruction wherein the computer refers to one or a cluster of computers, personal computers, workstations, mainframes, or combinations of computers thereof.


One embodiment of the presently claimed invention discloses a multiple auditory-pathway (“MAP”) earphone which is coupled to an external electronic system for converting electrical signals into various types of audio and vibration outputs that signal to various auditory pathways at the same time. The MAP earphone includes an earpiece, a first sound driver, and a second sound driver. In one aspect, the earpiece is configured to be inserted into an ear canal for providing audio sound. The first sound driver can produce audio output, mechanical output, and vibration output, while the second sound driver can generate only audio output. The vibration output transmits a signal through the newly discovered auditory pathway via a portion of ear cartilage lining the ear canal. The audio output and the mechanical output relay audio through another auditory pathway via the user's ear drum.


For example, the MAP earphone includes a first sound driver and a second sound driver for facilitating generation of 3D audio output with ultra bass sensation through multiple auditory pathways. The first sound driver, in one aspect, produces audio output, mechanical output and the vibration output. The second sound driver generate the audio output. The vibration output, in one embodiment, facilitates audio hearing by a user through a new auditory pathway via a portion of ear cartilage. The audio output and the mechanical output facilitate generation of audio hearing by the user through another auditory pathway via user's ear drum. To provide ultra bass sound effect, the MAP earphone produces different types of audio outputs and vibration output concurrently via multiple auditory pathways. For example, when two (2) auditory pathways of a listener receive different signals simultaneously, the listener brain may likely create a sound illusion which have the effects of a 3D audio output with ultra-bass sensation.



FIG. 1 illustrates diagram 100 showing a corded and cordless set of MAP earphones 101-102 capable of delivering auditory and vibrational output in accordance with one embodiment of the present invention. MAP earphone 101 is a corded, cable, or wired MAP earphone 101 capable of providing auditory and vibrational output. MAP earphone 102 is functionally similar to the MAP earphone 101 that is cordless or wireless. In one aspect, MAP earphone 101 includes a right receiver 105, left receiver 106, cord or cable 121, and an electrical audio signal 107. MAP earphone 102 includes a right receiver 105 and a left receiver 106. In another aspect, MAP earphone 102 has a built-in wireless communication circuit or component. It should be noted that the underlying concept of the exemplary embodiment(s) of the present invention would not change if one or more components (circuit or elements) were added to or removed from FIG. 1.


MAP earphone 101 or 102, also known as ultra-bass Metaverse earphone, is able to play music, radio stations, audio output from video broadcastings, television broadcasting, real-time sport events, interactive conversation, et cetera. The auditory and vibrational output from MAP earphone 101 or 102 to different auditory pathways in the human brain results in a 3D surround-sound sensation which can enhance listening enjoyment. Referring to FIG. 1, MAP earphone 101 includes 2 pieces of right and left receivers 105-106. Electrical audio signals are received by MAP earphone 101 via an electrical audio input 107 which is coupled to receivers 105-106 via a connecting cable 121. For example, a printed circuit board in MAP earphone 101 is used for signal transmission. MAP earphone 102, in one aspect, includes a wireless transmission component for handling wireless signal transmission. It should be noted that wireless transmission includes, but is not limited to, Bluetooth, Wi-Fi, Zigbee, microwave transmission, cellular transmission, and the like.


MAP earphone 101 or 102, in one example, is constructed by combing multi-drivers with chamber effects which create a lot of sound effects that greatly enhance listening and/or hearing enjoyment. An advantage of employing MAP earphone 101 or 102 is to increase hearing enjoyment such as ultra-bass and real bass performance, spatial and surround audio effects through the earphone. It should be noted that left receiver 106 of MAP earphone 101 or 102 should be the same appearance and construction as right receiver 105.



FIG. 2A is a diagram 200 illustrating an exemplary MAP earphone inserted in an ear showing contacting points associated to an ear in accordance with one embodiment of the present invention. Diagram 200 illustrates a user ear 270 and MAP earphone 272 wherein MAP earphone 272 is plugged into the user's ear between the ear cartilage 260 and ear canal 256. MAP earphone 272 includes a soft ear adaptor 218, housing 258, and cable 121. It should be noted that the underlying concept for the exemplary embodiment(s) of the present invention would not change if one or more components (circuit or elements) were added to or removed from FIG. 2A.


User ear 270 illustrates a normal human ear anatomy showing pinna 276, cartilage 260, ear canal 256, ear drum 252, inner ear cochlea 278, middle ear bones 280, auditory nerve 282. Upon coupling MAP earphone 272 to the user ear 270, MAP earphone 272 can generate audio sound 266 and vibration sound 262. Audio sound 266 is transmitted through the user's inner ear cochlea 278 via ear drum 252. Simultaneously, vibration 250 of cartilage 260 transmits a signal directly from the cartilage cells to the brain without passing through the normal auditory hearing system. This new auditory hearing system relays additional information that can be used to create sound illusions.


MAP earphone 272, in one embodiment, includes at least two sound drivers capable of generating different types of the audio and vibration outputs at the same time in different auditory pathways to the brain to create the 3D surround-sound and ultra-bass sensation. This is accomplished through two sensory pathways (audio and vibration) stimulated by a single source of electronic audio signals. For example, if one of the two sound drivers is used to generate a vibration with a predefined vibration direction for providing vibration sound, then another one of the two sound drivers can be configured to provide audio sound.


MAP earphone 272 is designed for a human ear. When worn by a user, MAP earphone 272 should be located at the entrance of ear canal near 256 ear pinna 276. The touching position or wearing position is at cartilage 260. The length of a human ear canal is usually around 1 inch (“in”). Beginning from the exterior of the ear, the first 2/5 of the ear canal are lined with soft tissue such as cartilage 260. The latter 3/5, stretching from the end of the cartilage 260 to the ear drum 252, is constructed exclusively from bone. The intended wearing position or touching position is against the cartilage of the ear canal. Thus, when worn correctly, the MAP earphone 272 should be positioned within the external 2/5 of the ear canal, resting against cartilage 260. Following the vibration direction 250, the MAP earphone 272 moves in and out in ear canal 256, creating a “rubbing process” which vibrates the cartilage 260, transmitting a new auditory signal to the brain. When these two auditory pathways simultaneously relay different signals to the auditory receiving centers, the brain will create a sound illusion of three-dimensional (“3D”) audio output and ultra-bass effects.


MAP earphone 272 includes two receivers, each of which includes one MEV driver 230 and one or more audio drivers 240. In one aspect, MAP earphone is configured to combine sound outputs from multiple audio drivers 240 to enhance and/or optimize sound quality and sensation.


An advantage of employing MAP earphone 272 is the production of audio with enhanced bass and improved 3D surround sound that enhances virtual reproduction of real-world soundscapes.



FIG. 2B is a diagram illustrating an exemplary MAP earphone 202 containing various components including at least two drivers in accordance with one embodiment of the present invention. MAP earphone 202 includes a back part 222, middle part 226, and earpiece 228 wherein back part 222 includes a mechanical-electromagnetic-vibration (“MEV”) driver 230 and middle part 226 includes an audio driver 240. It should be noted that the underlying concept of the exemplary embodiment(s) of the present invention would not change if one or more components (circuit or elements) were added to or removed from FIG. 2B.


Back part 222, in one example, includes a back plastic cover 220, MEV driver 230, and cable connection 121. Back plastic cover 220 is a back cover of MAP earphone configured to house MEV driver 230 and cable connection 118 coupling to cable 121. In one aspect, MEV driver 230 includes an electromagnetic sound generator and mechanical sound generator. It should be noted that the electromagnetic sound generator is configured to produce an electromagnetic audio output and mechanical sound generator generates mechanical audio output as well as vibration output. Cable connection 118 is used to provide a connection between MEV driver 230 and a phone terminal, not shown in FIG. 2B. A function of phone terminal or plug is to transmit electrical audio signals from an audio source to MAP earphone.


Middle part 226 includes a front plastic cover 210, acoustic chamber 212, audio driver or device 240, and emission hole 211. Front plastic cover 210 is a seating place for a second audio device or devices 240 with resonation at acoustic chamber 212. A function of middle part 226 is to produce audio sound as indicated by numeral 266 through an emission hole 211 to reach listener through ear drum 252.


Front plastic cover 210 is a plastic cover used for protecting and/or housing second audio devices or driver 240 which produces resonant performance of MAP earphone 202. Front plastic cover 210 also facilitates a connection between MEV driver 230 and second audio devices 240. Emission hole 211 is located at the front portion of MAP earphone 202. It should be noted that emission hole's length and size will affect the resonant performance of MAP earphone 202. Acoustic chamber 212 is located inside of front plastic cover 210 and offers a seating place for second audio device or devices 240 for generation of resonant performance and sound production out of earpiece 228.


Audio driver or second audio device(s) 240 is positioned in front of MEV driver 230 with respect to a user ear when MAP earphone 202 is inserted into the user ear. Depending on the applications, one or more audio devices 240 can be installed in middle part 226. The number of audio devices used should affect frequency response curve and/or output of MAP earphone 202. Second audio device or audio driver 240 can be fabricated via electromagnetic type, piezoelectric type, dynamic type, mechanical type, armature type, or a combination of electromagnetic, piezoelectric, dynamic, mechanical, and/or armature type components. In one example, additional audio devices or drivers 240 can be employed to provide a full range of audio frequency.


Soft ear adaptor 218 is situated or located at the end of MAP earphone 202 and is used to directly contact the cartilage in a human ear canal. In one embodiment, soft ear adaptor 218 is constructed by a thin plastic layer allowing transmitting various vibration frequencies from MEV driver 230 to soft ear adaptor 218. It should be noted that size of soft ear adaptor 218 which is fitted in a user ear is critical in affecting performance of spatial and surround sound effects. For example, a user needs to select a suitable size of soft ear adaptor 218 based on dimension of user ear canal. If soft ear adaptor 218 plugging into user ear is too tight, the effects of audio output, for instance, would be too strong. If, however, the fitting between soft ear adaptor 218 and ear canal is too loose, the effects would be too weak. In operation, users need to try and select the right size for their ears to obtain the best performance.


Upon receipt of electrical audio signals, audio driver or drivers 240 generate at least in part frequency response as reaction flow. Audio driver 240, in one aspect, provides one channel or pathway of sound output of MAP earphone 202. For example, audio driver 240 is capable of providing audio output from mid to high range of audio frequency. The electrical audio input via cable 121 to MEV driver 230 and audio driver 240 are the same or similar with similar time domain and phase orientation.


Audio driver or drivers 240 include electromagnetic drivers, such as, but not limited to, electro-magnetic speakers, electro-magnetic receivers, dynamic speakers, dynamic receivers, miniature speakers, and miniature receivers. It should be noted that armature type or piezo type sound generators may be used by audio driver 240. Different types and numbers of additional audio devices will have different frequency response curves of MAP earphone 202. Note that audio driver 240 can be adjusted in resistance and/or impedance to match with audio and vibration outputs of MEV driver 230 to optimize audio output. It should be noted that the audio driver is configured to generate audio output to a usual auditory system.


MEV driver 230, also known as DB Koo ultra-bass driver, includes an electromagnetic sound generator and a mechanical sound generator. The electromagnetic sound generator and the mechanical sound generator, in one embodiment, share common parts. MEV driver 230, in one example, generates a vibration output from a series of vibration which leads vibrations at one or more contact points of user ear for creating a new auditory pathway. The vibration output generated by MEV driver 230 travels through a new auditory system to the user's brain to create sound illusions such as a 3D surround sound sensation. It should be noted that MEV driver 230 plus one or more additional audio drivers 240 are constructed in each receiver of MAP earphone 202.


In operation, upon receipt of an electrical audio input as audio source through a connecting cable 121, MEV driver 230 and audio driver 240 generate multiple audio outputs via multiple mechanisms originating from the single audio source. The multi-outputs or multiple audio outputs include at least an audio output and a vibration output. It should be noted that MAP earphone 202 can also receive electrical audio input via a wireless transmission through a wireless network.


The vibration output, in one example, generates a range of amplitude from minimum to maximum amplitudes and frequencies. The vibration output of MAP earphone 202 allows a user to listen audio sound through vibration and/or rubbing against the cartilage of a user ear. In one embodiment, the vibration output emits or broadcasts audio signals or sound to a user via a new auditory pathway of a human listening or hearing system. The advantage of providing vibration output is to stimulate user brain experiencing enhance hearing enjoyment and facilitate the generation of sound illusions.


To provide electrical audio input with multiple audio outputs, MAP earphone 202 employs at least one MEV driver 230 and at least one audio driver 240. MEV driver 230, in one embodiment, is configured to generate three (3) type of audio outputs in accordance with a single audio input. The first audio output is an electro-magnetic audio output generated through an electromagnetic mechanism using an electromagnetic sound generator. The second audio output is a mechanical audio output generated from a mechanical mechanism using a mechanical sound generator. The third mechanical output is a vibration output generated through a vibration mechanical mechanism using a mechanical sound generator. The vibration output produces the rubbing process in the user's ear canal cartilage, leveraging a newly discovered auditory pathway to create a 3D surround sound sensation.


Audio driver 240, also known as second audio device or devices, is used to compensate an additional range of audio output which MEV driver 230 does not cover. To provide a full-range audio performance, MAP earphone 202 employs at least one audio driver 240 to optimize audio output. Audio driver 240, in one example, can be electromagnetic type, piezoelectric type, dynamic type, mechanical type or armature type audio devices or components.


MAP earphone 202, in one embodiment, employs an earpiece 228, a first sound driver or MEV driver 230 and a second sound driver or audio driver 240 to convert electrical signals to various audio and vibration outputs that synchronously stimulate different auditory pathways to perform sound illusion. Earpiece 228, in one example, is fabricated with soft material so that when it is inserted into a user ear canal, earpiece 228 can transmit vibration output of audio sound via the soft material. Examples of suitable soft material include, but are not limited to: plastic, silicon, rubber, and/or a combination of plastic, silicon, metal, and/or rubber. In operation, soft ear adaptor 218 of earpiece 228 is configured to be fitted inside ear canal whereby the vibration of soft ear adaptor 218 against ear cartilage 260 allows the user to receive or hear vibration sound or output.


The first sound driver, in one embodiment, is MEV driver 230 coupled to earpiece 228 operable to generate a vibration output used for facilitating audio hearing by a user through a first auditory pathway 262 via at least a portion of ear cartilage 260. In one aspect, the first sound driver includes an electromagnetic sound generator configured to generate electromagnetic audio and a mechanical sound generator configured to generate mechanical sound. The mechanical sound generator, in one example, is configured to facilitate generation of the vibration output.


The second sound driver, in one embodiment, is audio driver 240 coupled earpiece 228 operable to generate a sound output as indicated by numeral 266 for facilitating broadcast of audio sound to listener through a second or typical auditory pathway via the user or listener's ear drum 252.


MEV driver 230, in one embodiment, includes various components including, but not limited to, a yoke component, a linear vertical vibrator, a moving diaphragm, and an audio calibration diaphragm for creating various audio and vibration outputs that utilize different auditory pathways to perform sound illusion. The yoke component, for example, includes at least one pin armature, magnet, and mass unit for facilitating sound generation. The linear vertical vibrator includes at least one pin armature lock, mechanical spring hole, dust cover, and yoke seating place for facilitating sound generation.


MAP earphone 202, in one embodiment, further includes a receiver configured to receive electrical audio input. While the receiver can be configured to receive electrical sound signals via a cable, it can also be configured to receive electrical signals via a wireless network.


An advantage of using MAP earphone is that through creating different audio and vibration outputs, different auditory pathways are simultaneously stimulated, resulting in sound illusion of enhanced bass effects that improve audio reality or on-site performance of content. Another advantage of using MAP earphone is to provide spatial audio effects which can be used to create illusions of direction, size, and movement of sound. This may be used, for instance, to generate the feel of a 360-sound field or 3D surround sound.



FIG. 3 is a diagram 300 illustrating auditory pathways associated to an MAP earphone in accordance with one embodiment of the present invention. Diagram 300 shows MAP earphone 272, ear anatomy 320, and brain anatomy 322. Ear anatomy 320 and brain anatomy 322, in one embodiment, are coupled by a first and a second auditory pathways 308-310. It should be noted that the underlying concept of the exemplary embodiment(s) of the present invention would not change if one or more anatomies (or elements) were added to or removed from FIG. 3.


Diagram 300 illustrates a new auditory system 330 and a normal auditory system 332 wherein new auditory system 330 includes first auditory pathway 308 and normal auditory system 332 contains second auditory pathway. A function of MAP earphone 272 is to involve both systems 330-332 to generate new listening or sound sensation(s). In the human hearing system, one or more auditory systems receive and/or transmit sound waves to parts of the brain such as the auditory receiving centers 302-306 for differentiating patterns of neural activity. The identified patterns of neural activities are subsequently integrated with inputs from other sensory systems to guide behavior such as orienting movements due to acoustic stimuli and intraspecies communication.


An auditory system, in one example, includes ear pinna, ear canal 256, ear drum 252, 3 inner ear bones 312, and inner ear 316. In one aspect, MAP earphone 272 is configured to stimulate newly discovered auditory system 330 which can detect vibration output of audio sound via rubbed or vibrating cells of cartilage 260. In operation, the vibration and rubbing process sends a signal to the brain through the new auditory pathway.


To enhance listening or hearing enjoyment with sound illusion, MAP earphone 272, in one embodiment, allows user's brain such as brain 322 to enjoy extraordinary sound sensation by providing multiple different sound outputs to two (2) auditory pathways 308-310. Note that generation of sound effect with real ultra-bass performance can be achieved via a small earpiece such as MAP earphone. It should be noted that through using multiple sound outputs to multiple auditory pathways, the MAP earphone 272 can achieve wider and fuller range of audio frequency with harmonics, creating more reality of sound. Note that new auditory system 330 is used to facilitate spatial audio effects.


An advantage of using MAP earphone is to produce analogue audio. For example, a listener hears sound which is not only transmitted from normal auditory system 332 but also from new auditory system 330 to reach brain 322. This may allow deaf or hearing-impaired people to experience the sound through an alternate auditory system 330.


To provide 3D surround sound, MAP earphone 272 employs necessary audio emissions to broadcast or stimulate both normal auditory system 332 and new auditory system 330. Auditory messages, in one example, are conveyed to the brain via two types of pathways, namely the primary auditory pathway such as second auditory pathway 310 which carries messages from the cochlea, and the non-primary pathway such as first auditory pathway 308 and/or reticular sensory pathway which carries sensory messages.


The normal auditory hearing system, also known as the normal auditory system 332, works as the usual hearing system wherein the listener can hear the sound through a collection of signals from the ear pinna, ear canal, 256, and ear drum 252. The movement of ear drum 252 leads to the movement of middle ear bones 312 which move the inner ear 316, stimulating the auditory nerve to transmit sound to brain via the normal auditory system 332.


MAP earphone 272 is configured to create vibration together with audio signal sources that form 2 sound outputs to brain. It should be noted that the linear movement against the ear canal cartilage provides a sound output to user via new auditory system 330. Due to multiple sound outputs by MAP earphone 272, the audio output will be transmitted to the brain via normal auditory system 332 and vibration output will be transmitted to the brain from new auditory system 330. An advantage of using both auditory systems 330-332 will assist deaf and/or hearing disable people for hearing. Another advantage of using MAP earphone 272 capable of broadcasting sound via both systems 330-332 is to create spatial audio or virtual reality audio in the applications of music, movie, game, e-sport, virtual reality application program, live program, and/or Metaverse related programs. The MAP earphone 272 can simultaneously produce different types of audio and vibration outputs that combine signals through different auditory pathways to the brain to provide ultra-bass effects, more audio reality, and/or onsite performance.



FIG. 4A is a block diagram illustrating first driver 400 of MAP earphone containing various components in accordance with one embodiment of the present invention. First driver, also known as MEV driver 400 includes a yoke 4, liner vertical vibrator 54, bridge 31, moving diaphragm 32, and audio calibration diaphragm 42. It should be noted that the underlying concept of the exemplary embodiment(s) of the present invention would not change if one or more components (circuit or elements) were added to or removed from FIG. 4A.


In one embodiment, MEV driver 400 includes an electromagnetic sound generator which is based on an electromagnetic mechanism. The electromagnetic sound generator is able to generate vibration output produced from movement of moving diaphragm 32 which moves the air molecules for sound transmission. To construct or fabricate MEV driver 400, an enameled voice coil 33 is rounded as a cylindrical tube which is glued or coupled to a symmetric placement of moving diaphragm 32. Moving diaphragm 32 is configured to affect the efficiency of induced electromagnetic force on moving diaphragm 32 for moving air molecules to transmit sound. The material of enameled voice coil 33 can be made by copper (“Cu”), silver (“Ag”), Aluminum (“Al”), gold (“Au”), and/or a combination of Cu, Ag, Al, and/or Au as alloys for distinct acoustic results of the electromagnetic sound generator. The length of enameled voice coil 33 can affect DC resistance and/or impedance value.


The number of turnings and thickness of enameled voice coil 33 will affect resistance and impedance, while the resistance and impedance affect tone balance as well as frequency response curve between the electromagnetic sound generator and mechanical sound generator. Enameled voice coil 33 is assembled at the center, facilitating a balance of moving diaphragm 32 in a round cylindrically shape or any other shapes. Moving diaphragm 32 is coupled or glued at bridge 31 and assembled or attached to power ring 44 as a node of vibration. Enameled voice coil 33 is located between the gap between pin armature 36 and mass 38. Note that enameled voice coil 33 can affect magnetic field generated from magnet 35, which provides induced electromagnetic force. A gap between yoke 41 and mass 38 is used to facilitate movement of enameled voice coil 33 up and down for affecting induced electromagnetic force. A winding method and number of turns of enameled voice coil 33 can affect electromagnetic force in accordance with a three-hand rule. The depth of enameled voice coil 33 into the gap for the movement of enameled voice coil 33 up and down also affects the electromagnetic force. The thickness, shape, and material of moving diaphragm 32 can also be important factor because it can affect the resonant frequency and frequency response curve which will affect the sound output.


MEV driver 400, in one embodiment, is placed or constructed near the back of MPA earphone while the audio driver or drivers are placed or constructed near the emission hole of MAP earphone. It should be noted that the distance between MEV driver 400 and audio driver can be important because the distance can affect the sound performance of MEV driver 400. To provide multi-output surround sound, MEV driver 400 contains a free-floating momentum yoke 4 and linear vertical vibrator 54.

Linear vertical vibrator (54) is composed from the center plate for yoke seating place 52 which is fixed to momentum yoke 4. Spring legs 53 are used to control the elasticity of mechanical spring 50. It should be noted that the number, thickness, and design of spring legs 53 can affect amplitude, response time, and damping performance of the vibration generated by MEV driver 400. Spring legs 53, in one example, extends from spring edge 55 which is fixed at bridge 31 to the center at the mechanical spring hole (521).


The end of the spring legs (53) near bridge 31 has a metal ring called drum plate 39. At the lowest part of yoke bottom 41, also known as pin armature lock (361), a distance is created with drum plate 39. The distance of pin armature lock (361) and drum plate 39, in one example, is fixed to ensure proper clearance of linear vertical vibrator 54 so that linear vertical vibrator 54 can properly hit at the highest position. The position of drum plate 39 is below the bottom of moment yoke 4. The printed circuit board 37 is used to connect enameled voice coil 33 and the audio driver. The center of printed circuit board 37 is audio calibration diaphragm 42 which is used to assist tuning of frequency response for MEV driver 400.

The movement of moving diaphragm 32 will move upward or downward depends on the direction of the current flow. For example, when the current flow is in a negative direction, direction of the electro-magnetic force may change to assist current flow direction. It should be noted that the up and down motion of moving diaphragm 32 can push air molecules to transmit sound as an audio output. It should be noted that different frequency of electric audio input can make different currents in the MAP earphone because different frequencies facilitate different sound pressure levels.

The mechanical audio output is generated until the falling momentum yoke 4 hitting on drum plate 39. It should be noted that the underlying concept of the exemplary embodiment(s) of the present invention would not change if one or more components (circuit or elements) were added to or removed from FIG. 9.


MEV driver 900 or 902, in one example, uses a mechanical sound generator to facilitate generation of vibration output. In operation, when moving diaphragm 32 is in motion, the electromagnetic sound generator is used to induce an electro-magnetic force. The motion of moving diaphragm 32, for example, will lead the movement of enameled voice coil 33 under the magnetic field from magnet 35 to react on momentum yoke 4, as illustrated in FIG. 4A. Momentum yoke 4 is configured to be a free-floating mechanism which is locked at linear vertical vibrator 54 and a side of bridge 31. When moving diaphragm 32 vibrates upwards and downwards, the motion translates motion of momentum yoke 4, linear vertical vibrator 54, and bridge 31. The force acting on bridge 31 will subsequently provide the vibration output of the MAP earphone. Note that the weight and construction of momentum yoke 4 is related to response, vibration amplitude, and resonant frequency.

Chart 1100 shows audio frequency response curve of MAP earphone containing information relating to response signal and tolerance(s). The frequency response curve combines audio outputs from all drivers to form the audio frequency characteristics. From chart 1100, the frequency response curve shows audio frequency characteristics having deep V-shape drops of sound pressure level around or before 200 hertz (“Hz”). The deep V-shape drop of the sound pressure level before 200 Hz, in one example, comes from an energy transfer from the electromagnetic sound generator to the mechanical sound generator. The deep V-shape drop frequency point below 200 Hz can be controlled based on the applications and/or control requirement. It should be noted that the transferred energy brings up the movement of the momentum yoke and the linear vertical vibrator in the mechanical sound generator.



FIG. 12 is a chart 1200 illustrating vibration amplitude associated to vibration audio output generated by the MAP earphone in accordance with one embodiment of the present invention in accordance with one embodiment of the present invention. In operation, after arrival of electrical audio input, the electro-magnetic sound system or electromagnetic sound generator activates a movement of the moving diaphragm in response to induce electro-magnetic force. The motion of the moving diaphragm induces the electro-magnetic force applied to the momentum yoke which leads to the motion of the linear vertical vibrator. Due to the fixture of the linear vertical vibrator at the bridge, the motion produces a vibration output from the MAP earphone. Chart 1200 shows total vibration energy of MAP earphone around 80-200 Hz. It should be noted that the minimum vibration amplitude is set up at the resonant frequency 20 mg when input voltage is 0.126 Vrms. Chart 1102 illustrates that minimum vibration amplitude of the MAP earphone and the rubbing frequency should be between 80-200 Hz as shown in FIG. 12.



FIG. 12 is a chart 1200 illustrating vibration response curve associated to vibration audio output generated by the MAP earphone in accordance with one embodiment of the present invention in accordance with one embodiment of the present invention. Chart 1200 illustrates a vibration frequency range between 80-200 Hz. Chart 1200 also shows the maximum vibration amplitude at the resonant frequency (around 140 Hz) for the MAP earphone. It should be noted that 140 Hz is approximately in the middle of 80 and 200 Hz. The vibration output is configured to transmit sound signals to the brain via a newly discovered auditory system using different frequencies and amplitudes. Different frequencies and amplitudes create different effects on rubbing the cartilage of the ear canal to transmit different frequencies of audio. It should be noted that a vibration frequency within 80-200 Hz includes the sub-woofer bass range, which enhances the bass feeling. In one embodiment, the vibration amplitude is a factor to generate sound illusion. For example, the minimum amplitude level of vibration is 20 mg under the input of 0.126 root mean square voltage (“Vrms”), and it varies based on different input voltages. The vibration will create the rubbing process on the surface of the cartilage in the ear canal and create the sound illusion output of the audio signal to the brain (the effect of the vibration) which is a secondary pathway of the auditory system.


The exemplary embodiment of the present invention includes various processing steps, which will be described below. The steps of the embodiment may be embodied in machine or computer-executable instructions. The instructions can be used to cause a general-purpose or special-purpose system, which is programmed with the instructions to perform the steps of the exemplary embodiment of the present invention.

Alternatively, the process can generate mechanical audio sound.


At block 1308, the process activates a second sound driver, also known as an audio driver, to generate a sound output in accordance with the electrical audio input for facilitating generation of the audio that may be perceived through a second auditory pathway via the user's ear drum.
