Description

Technical Field

[0001] Exemplary embodiments of the present invention relate to the field of electronic devices such as smartphones, computers, televisions, handheld consoles, radios, etc. More specifically, exemplary embodiments of the present invention relate to headphones for audio broadcasting. Background Art

[0002] Traditional headphones, also known as earbuds or in-ear headphones, are small audio devices that can convert an electroacoustic signal or energy into sound frequencies or sound waves for audio output. A typical headphone can be designed to be applied inside the ear canal and can also be worn by a user and inserted into the ear. For example, generally, headphones are connected to an audio source, such as a smartphone, a tablet computer, a computer, or an MP3 player, either by wire or wireless Bluetooth.

[0003] Since headphones are usually compact, lightweight, and highly portable, they are a popular choice for eliminating noise and listening to various forms of media, including music, news, concerts, sports games, movies, and video games. Traditional headphones usually have various limitations or drawbacks, such as, but not limited to, lack of spatial audio, lack of surround sound audio, lack of bass, etc. In addition, people with hearing impairment or deafness usually cannot use traditional headphones.

[0004] Therefore, there is a need for a headphone that can provide an ultra-low audio effect and a 3D surround sound effect, and can also be used as a hearing aid for deaf people. Summary of the Invention

[0005] In one embodiment of the present invention, a multi-auditory pathway (“MAP”) headphone coupled to an external electronic system for receiving an audio input signal is disclosed. The MAP headphone includes earbuds, a first sound driver, and a second sound driver. On the one hand, the provided earbuds are inserted into the ear canal to provide audio sound. The first sound driver is operable to generate a vibration output, and the vibration output passes through a part of the sensitive position of the ear canal through a newly discovered auditory pathway (also known as a new auditory pathway) to promote the user's hearing. The provided second sound driver generates a sound output, and the sound output passes through the user's eardrum through another auditory pathway to promote the user's audio hearing. The first sound driver can generate an audio output, a mechanical output, and a vibration output, while the second sound driver can only generate an audio output. The vibration output passes through the newly discovered auditory pathway and transmits signals through a part of the sensitive position of the ear canal inside the ear. The audio output and the mechanical output pass through the user's eardrum and transmit audio through another auditory pathway.

[0023] Embodiments of the present invention disclose methods and / or apparatuses for providing three-dimensional ("3D") audio output and ultra-low sound effects through multi-auditory path ("MAP") headsets. The MAP headset can simultaneously generate different types of audio output and vibration output. When two auditory paths simultaneously receive different signals from the auditory reception center, the brain generates an auditory illusion of three-dimensional ("3D") audio output with ultra-low sound effects.

[0024] The purpose of the following detailed description is to provide an understanding of one or more embodiments of the present invention. Those of ordinary skill in the art will recognize that the following detailed description is merely illustrative and is not intended to limit in any way. Those skilled in the art who benefit from the present disclosure and / or description can easily think of other embodiments.

Additionally, those of ordinary skill in the art will recognize that less general-purpose devices, such as hardware devices, field-programmable gate arrays (FPGAs), application-specific integrated circuits (ASICs), etc., can also be used without departing from the scope and spirit of the inventive concepts disclosed in this specification. When implementing a method including a series of processing steps using a computer or machine, and these processing steps can be stored as a series of machine-readable instructions, these processing steps can be stored on a tangible medium, such as a computer storage device (e.g., ROM (read-only memory), PROM (programmable read-only memory), EEPROM (electrically erasable programmable read-only memory), FLASH memory, Jump Drive, etc.), magnetic storage media (e.g., magnetic tape, disk drive, etc.), optical storage media (e.g., CD-ROM, DVD-ROM, paper cards, and paper tapes, etc.), and other known types of program memories.

[0028] The term "system" or "device" is generally used herein to describe any number of components, elements, subsystems, devices, packet-switching elements, packet switches, access switches, routers, networks, computers, and / or communication devices or mechanisms, or combinations of their components. The term "computer" includes a processor, a memory, and a bus capable of executing instructions, where a computer refers to one or a group of computers, personal computers, workstations, mainframes, or combinations thereof.

[0029] One embodiment of the present invention discloses a multi-auditory pathway ("MAP") headphone that is coupled to an external electronic system for converting electroacoustic signals into various types of audio and outputting the signals to various auditory pathways simultaneously. The MAP headphone includes earbuds, a first sound driver, and a second sound driver. On the one hand, the provided earbuds are inserted into the ear canal to provide audio sounds. The first sound driver can generate audio output, mechanical output, and vibration output, while the second sound driver can only generate audio output. The vibration output transmits signals through a newly discovered auditory pathway via a sensitive part of the ear tube in the ear canal. The audio output and mechanical output are transmitted through the user's eardrum to deliver audio through another auditory pathway.

[0030] For example, the MAP headphones include a first sound driver and a second sound driver for promoting the generation of a 3D audio output with a sub - bass feeling through multiple auditory channels. On the one hand, the first sound driver generates an audio output, a mechanical output, and a vibration output. The second sound driver generates an audio output. In one embodiment, the vibration output promotes the user's audio hearing through a new auditory channel via a part of the sensitive bit of the ear canal. The audio output and the mechanical output facilitate the user's audio hearing via the user's eardrum through another auditory channel. To provide an ultra - low sound effect, the MAP headphones simultaneously generate different types of audio outputs and vibration outputs through multiple auditory channels. For example, when the two (2) auditory channels of a listener receive different signals simultaneously, the listener's brain may generate an auditory illusion, the effect of which is similar to a 3D audio output with a sub - bass feeling.

[0031] Figure 1 FIG. 100 is a schematic diagram of a set of wired and cordless MAP headphones 101 - 102 capable of transmitting auditory and vibration outputs in an exemplary embodiment of the present invention. MAP headphone 101 is a wired, cabled, or corded MAP headphone 101 capable of providing auditory and vibration outputs. MAP headphone 102 is functionally similar to a cordless or wireless MAP headphone 101. On the one hand, MAP headphone 101 includes a right earplug 105, a left earplug 106, wires or cables 121, and a plug 107. MAP headphone 102 includes a right earplug 105 and a left earplug 106. In another aspect, MAP headphone 102 has a built - in wireless communication circuit or component. It should be noted that if one or more components (circuits or elements) are added to or removed from Figure 1 add or from Figure 1 the basic concept of the exemplary embodiments of the present invention will not change.

[0032] The MAP headphones 101 or 102, also known as sub - bass Metaverse headphones, are capable of playing music, radio stations, playing the audio output of video broadcasts, television broadcasts, live sports events, interactive conversations, etc. The auditory and vibration outputs from the MAP headphones 101 or 102 to different auditory channels in the human brain produce a 3D surround sound effect, enhancing the auditory enjoyment. Referring to Figure 1 , MAP headphone 101 includes 2 earplugs, a left earplug 106 and a right earplug 105. MAP headphone 101 receives an electronic audio input through a plug 107, and the electronic audio input is connected to the earplugs 105 - 106 through a connecting cable 121. For example, the printed circuit board in MAP headphone 101 is used for signal transmission. On the one hand, MAP headphone 102 includes a wireless transmission component for processing wireless signal transmission. It should be noted that wireless transmission includes but is not limited to Bluetooth, Wi - Fi, Zigbee, microwave transmission, cellular transmission, etc.

[0033] In one example, the MAP earphones 101 or 102 are constructed of a multi-driver with a chamber effect, and the multi-driver generates a large number of sound effects, greatly enhancing hearing and / or auditory enjoyment. The advantage of using the MAP earphones 101 or 102 is that the auditory enjoyment is enhanced through the earphones, such as subwoofer and true bass performance, spatial and surround audio effects. It should be noted that the appearance and construction of the left earbud 106 of the MAP earphones 101 or 102 should be the same as that of the right earbud 105.

[0034] Figure 2A Schematic diagram 200 of an exemplary MAP earphone inserted into the ear for an embodiment of the present invention, showing the contact points related to the ear. Figure 200 shows a user's ear 270 and a MAP earphone 272, and the MAP earphone 272 is inserted between the sensitive position 260 of the ear canal and the ear canal 256 of the user's ear. The MAP earphone 272 includes a soft ear adapter 218, a housing 258, and a cable 121. It should be noted that if one or more components (circuits or elements) are added or deleted Figure 2A the basic concept of the exemplary embodiment of the present invention will not change.

[0035] The user's ear 270 shows the normal anatomical structure of the human ear, and the anatomical structure shows the auricle 276, the sensitive position 260 of the ear canal, the ear canal 256, the eardrum 252, the cochlea 278 of the inner ear, the middle ear bones 280, and the auditory nerve 282. When the MAP earphone 272 is coupled to the user's ear 270, the MAP earphone 272 can generate an audio sound 266 and a vibration sound 262. The audio sound 266 is transmitted through the user's inner ear cochlea 278 via the eardrum 252. At the same time, the vibration 250 of the sensitive position 260 of the ear canal transmits the signal directly from the cells of the sensitive position of the ear canal to the brain without passing through the normal auditory system. This new auditory system transmission can be used to generate additional information for auditory hallucinations.

[0036] In one embodiment, the MAP earphone 272 includes at least two sound drivers, and the sound drivers are capable of simultaneously generating different types of audio and vibration outputs in different auditory pathways reaching the brain to produce 3D surround sound and subwoofer effects. This is achieved through two sensory pathways (audio and vibration) stimulated by a single electronic audio signal source. For example, if one of the two sound drivers is used to generate vibrations with a predefined vibration direction to provide vibration sounds, then the other of the two sound drivers is set to provide audio sounds.

[0037] The MAP earphone 272 is designed for the human ear. When the user wears the MAP earphone 272, the MAP earphone 272 should be located at the entrance of the ear canal 256, near the auricle 276. The touch position or the wearing position is at the sensitive position 260 of the ear canal. The length of the human ear canal is typically about 1 inch ("in"). Starting from the outside of the ear, the first 2 / 5 of the ear canal is lined with soft tissues such as the sensitive position 260 of the ear canal. The remaining 3 / 5 extends from the end of the sensitive position 260 of the ear canal to the eardrum 252 and is entirely composed of bone. The expected wearing position or touch position is against the sensitive position of the ear canal. Therefore, when worn correctly, the MAP earphone 272 should be within the outer 2 / 5 of the ear canal, against the sensitive position 260 of the ear canal. Along the vibration direction 250, the MAP earphone 272 moves in and out of the ear canal 256, generating a "friction process" that vibrates the sensitive position 260 of the ear canal and transmits new auditory signals to the brain. When these two auditory pathways simultaneously transmit different signals to the auditory reception center, the brain produces an auditory illusion with three-dimensional ("3D") audio output and subwoofer effects.

[0038] The MAP earphone 272 includes two earbuds, each earbud including a MEV driver 230 and one or more audio drivers 240. On the one hand, MAP is set to combine the sound outputs from multiple audio drivers 240 to enhance and / or optimize the sound quality and sound effects.

[0039] The advantage of using the MAP earphone 272 is to produce audio with enhanced bass and improved 3D surround sound, thereby enhancing the virtual reproduction of the real-world soundscape.

[0040] Figure 2B is a schematic diagram showing an exemplary MAP earphone 202 containing various components (including at least two drivers) in an embodiment of the present invention. The MAP earphone 202 includes a back 222, a middle 226, and a soft ear adapter 228. The back 222 includes a mechanical electromagnetic vibration ("MEV") driver 230, and the middle 226 includes an audio driver 240. It should be noted that if Figure 2B add or remove one or more components (circuits or elements) from Figure 2B the basic concept of the exemplary embodiment of the present invention will not change.

[0041] In one example, the rear portion 222 includes a rear plastic cover 220, an MEV driver 230, and a cable connection 121. The rear plastic cover 220 is the rear cover of the MAP earphone and is configured to accommodate the MEV driver 230 and the cable connection 118 coupled to the cable 121. On one hand, the MEV driver 230 includes an electromagnetic sound generator and a mechanical sound generator. It should be noted that the provided electromagnetic sound generator generates an electromagnetic audio output, and the mechanical sound generator generates a mechanical audio output as well as a vibration output. The cable connection 118 is used to provide a connection between the MEV driver 230 and a telephone terminal ( Figure 2B not shown in the figure). The function of the telephone terminal or the plug is to transmit an electronic audio signal from an audio source to the MAP earphone.

[0042] The middle portion 226 includes a front plastic cover 210, a sound chamber 212, an audio driver 240, and an emission hole 211. One or more audio drivers 240 having resonance at the position of the sound chamber 212 are located on the front plastic cover 210. The function of the middle portion 226 is to generate an audio sound as shown by the air particle transfer 266 through the emission hole 211 and reach the listener through the eardrum 252.

[0043] The front plastic cover 210 is a plastic cover for protecting and / or accommodating the audio driver 240 that generates the resonance performance of the MAP earphone 202. The front plastic cover 210 also facilitates the connection between the MEV driver 230 and the audio driver 240. The emission hole 211 is located at the front of the MAP earphone 202. It should be noted that the length and size of the emission hole will affect the resonance performance of the MAP earphone 202. The sound chamber 212 is located inside the front plastic cover 210, providing a housing position for the audio driver 240 to generate resonance performance and emit sound from the earphone 228.

[0044] When the MAP earphone 202 is inserted into the user's ear, the audio driver or audio drivers 240 are located in front of the MEV driver 230 relative to the user's ear. Depending on the application, one or more audio drivers 240 can be installed in the middle portion 226. The number of audio devices used should affect the frequency response curve and / or output of the MAP earphone 202. The audio driver 240 can be manufactured by an electromagnetic type, piezoelectric type, dynamic type, mechanical type, armature type component, or a combination of electromagnetic, piezoelectric, dynamic, mechanical, and / or armature type components. In one example, an additional audio driver 240 can be employed to provide a full range of audio.

[0045] The soft ear adapter 218 is at or near the end of the MAP earphone 202 and is used to directly contact the sensitive part of the ear canal in the human ear. In one embodiment, the soft ear adapter 218 is composed of a thin plastic layer that transmits various vibration frequencies from the MEV driver 230 to the soft ear adapter 218. It should be noted that the size of the soft ear adapter 218 installed in the user's ear has a crucial impact on the performance of space and surround sound effects. For example, the user needs to select a soft ear adapter 218 with a suitable size based on the size of the user's ear canal. If the soft ear adapter 218 inserted into the user's ear is too tight, the audio output effect will be too strong. However, if the fit between the soft ear adapter 218 and the ear canal is too loose, the audio output effect will be too weak. In operation, the user needs to try to select a size suitable for their own ear to obtain the best performance.

[0046] After receiving an electronic audio signal, one or more audio drivers 240 at least partially generate a frequency response as a reaction stream. On the one hand, the audio driver 240 provides the sound output of the MAP earphone 202 for one channel or path. For example, the audio driver 240 can provide audio output from the mid-frequency to the high-frequency. The electronic audio input via the cable 121 to the MEV driver 230 and the audio driver 240 is the same or similar in the time domain and phase direction.

[0047] The audio driver 240 includes electromagnetic drivers, such as, but not limited to, electromagnetic speakers, electromagnetic receivers, dynamic speakers, dynamic receivers, micro speakers, and micro receivers. It should be noted that the audio driver 240 can use an armature type or a piezoelectric type sound generator. When the types and quantities of additional audio devices are different, the frequency response curve of the MAP earphone 202 is also different. Note that the resistance and / or impedance of the audio driver 240 can be adjusted to match the audio and vibration outputs of the MEV driver 230, thereby optimizing the audio output. It should be noted that the audio driver is set to generate an audio output for a conventional auditory system.

[0048] The MEV driver 230, also known as the DB-Koo subwoofer driver, includes an electromagnetic sound generator and a mechanical sound generator. In one embodiment, the electromagnetic sound generator and the mechanical sound generator share common components. In one example, the MEV driver 230 generates a vibration output in a series of vibrations that cause vibrations at one or more contact points of the user's ear to create a new auditory pathway. The vibration output generated by the MEV driver 230 is transmitted to the user's brain through the new auditory system to generate auditory illusions, such as 3D surround sound effects. It should be noted that the MEV driver 230 is provided in each earplug of the MAP earphone 202, plus one or more additional audio drivers 240.

[0049] In operation, after receiving an electronic audio input as an audio source through the connection cable 121, the MEV driver 230 and the audio driver 240 generate multiple audio outputs through multiple mechanisms derived from a single audio source. The multi-output or multiple audio outputs at least include an audio output and a vibration output. It should be noted that the MAP headset 202 can also receive an electronic audio input via wireless transmission through a wireless network.

[0050] In one example, the vibration output generates an amplitude range from a minimum amplitude and frequency to a maximum amplitude and frequency. The vibration output of the MAP headset 202 can vibrate and / or rub the sensitive parts of the user's ear canal, allowing the user to listen to the audio. In one embodiment, the vibration output emits or broadcasts an audio signal or sound to the user through a new auditory pathway of the human auditory or hearing system. The advantage of providing the vibration output is to stimulate the user's brain experience, enhance auditory enjoyment, and promote the generation of auditory hallucinations.

[0051] To provide an electronic audio input with multiple audio outputs, the MAP headset 202 employs at least one MEV driver 230 and at least one audio driver 240. In one embodiment, the provided MEV driver 230 generates three types of audio outputs based on a single audio input. The first type of audio output is an electromagnetic audio output, generated by an electromagnetic mechanism via an electromagnetic sound generator. The second type of audio output is a mechanical audio output, generated by a mechanical mechanism via a mechanical sound generator. The third type of mechanical output is a vibration output, generated by a vibrating mechanical mechanism via a mechanical sound generator. The vibration output creates a friction process in the sensitive parts of the user's ear canal, using the newly discovered auditory pathway to create a 3D surround sound effect.

[0052] The audio driver 240, also known as the second sound driver, is used to compensate for the additional audio output range not covered by the MEV driver 230. To provide a full range of audio performance, the MAP headset 202 employs at least one audio driver 240 to optimize the audio output. In one example, the audio driver 240 can be an electromagnetic, piezoelectric, dynamic, mechanical, or armature type audio device or component.

[0053] In one embodiment, the MAP headset 202 uses a soft ear adapter 228, a first sound driver or MEV driver 230, and a second sound driver or audio driver 240 to convert an electroacoustic signal into various audio and vibration outputs that synchronously stimulate different auditory pathways to achieve audio hallucination. In one example, the soft ear adapter 228 is made of a soft material, so when the soft ear adapter 228 is inserted into the user's ear canal, the soft ear adapter 228 can transmit the vibration output of the audio sound through the soft material. Examples of suitable soft materials include, but are not limited to: plastics, silicone, rubber, and / or combinations of plastics, silicone, metals, and / or rubber. In operation, the provided soft ear adapter 228 is installed in the ear canal, and for this purpose, the vibration generated by the soft ear adapter 228 against the sensitive position 260 of the ear canal allows the user to receive or hear the vibration sound or output.

[0054] In one embodiment, the first sound driver is a MEV driver 230 coupled to the soft ear adapter 228, which can generate a vibration output through operation. The vibration output enhances the user's audio hearing through the first auditory pathway 262 via at least a portion of the sensitive position 260 of the ear canal. On the one hand, the first sound driver includes an electromagnetic sound generator configured to generate electromagnetic audio and a mechanical sound generator configured to generate mechanical sound. In one example, the provided mechanical sound generator facilitates the generation of the vibration output.

[0055] In one embodiment, the second sound driver is an audio driver 240 coupled to the soft ear adapter 228, which can generate a sound output as shown by the air particle transfer 266 through operation and play the audio to the listener through the second auditory pathway or the typical auditory pathway via the tympanic membrane 252 of the user or listener.

[0056] In one embodiment, the MEV driver 230 includes various components, including but not limited to a yoke, 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 audio hallucination. For example, the yoke includes at least one pin armature, a magnet, and a weight unit to facilitate the generation of sound. The linear vertical vibrator includes at least one pin armature lock, a mechanical spring hole, a dust cover, and a yoke seat to facilitate the generation of sound.

[0057] In one embodiment, the MAP headset 202 further includes a player configured to receive an electronic audio input. Although the player can be configured to receive an electroacoustic signal through a cable, it can also be configured to receive an electroacoustic signal through a wireless network.

[0058] One advantage of using MAP headphones is that by creating different audio and vibration outputs, different auditory pathways can be stimulated simultaneously, resulting in auditory illusions with enhanced bass effects, improving audio reality or live performance. Another advantage of using MAP headphones is to provide spatial audio effects that can be used to create illusions of sound directionality, size, and movement. For example, it can be used to generate a 360-degree sound field or 3D surround sound effects.

[0059] Figure 3 is a schematic diagram showing the auditory pathway 300 associated with MAP headphones in an embodiment of the present invention. Figure 300 shows the MAP headphones 272, the ear anatomy 320, and the brain anatomy 322. In one embodiment, the ear anatomy 320 and the brain anatomy 322 are coupled through the first auditory pathway 308 and the second auditory pathway 310. It should be noted that if one or more anatomies (or elements) are added to Figure 3 or deleted from Figure 3 , the basic concept of the exemplary embodiments of the present invention will not change.

[0060] Figure 300 shows a novel auditory system 330 and a normal auditory system 332, where the novel auditory system 330 includes the first auditory pathway 308, and the normal auditory system 332 includes the second auditory pathway. The function of the MAP headphones 272 is to generate new listening or sound effects involving the two systems 330-332. In the human auditory system, one or more auditory systems receive sound waves and / or transmit sound waves to certain parts of the brain, such as the auditory reception centers 302-306, to distinguish patterns of neural activity. Subsequently, the identified patterns of neural activity are combined with inputs from other sensory systems to guide behavior, such as directional movement due to sound stimulation and intraspecific communication.

[0061] In one example, the normal auditory system includes the auricle, the ear canal 256, the eardrum 252, three inner ear bones 312, and the inner ear 316. On the one hand, the provided MAP headphones 272 stimulate the newly discovered auditory system 330, which can detect the vibration output of audio sounds through the friction or vibration elements of the sensitive position of the eustachian tube 260. During operation, signals are sent to the brain through the new auditory pathway during the vibration and friction process.

[0062] To enhance listening or hearing enjoyment through audio magic, in one embodiment, the MAP earphones 272 provide multiple different sound and vibration outputs to two (2) auditory pathways 308-310, allowing the user's brain (e.g., brain 322) to enjoy extraordinary sound effects. Note that small earbuds, such as MAP earphones, can achieve sound effects with true sub-bass performance. It should be noted that by using multiple sound outputs transmitted to multiple auditory pathways, the MAP earphones 272 can provide a wider and more complete harmonic audio range, creating a more realistic sound. It should be noted that the new hearing system 330 is used to enhance spatial audio effects.

[0063] One advantage of using MAP headphones is that they produce simulated audio. For example, the listener hears not only the sounds transmitted from the normal auditory system 332, but also the sounds transmitted from the novel auditory system 330 to the brain 322. This allows deaf or hearing-impaired people to experience sound effects through the alternative auditory system 330.

[0064] To provide 3D surround sound, the MAP earphones 272 use the necessary audio transmission to broadcast to or stimulate the normal auditory system 332 and the novel auditory system 330. In one example, auditory information is transmitted to the brain through two types of pathways, namely, a primary auditory pathway, such as the secondary auditory pathway 310 that carries information from the cochlea, and a non-primary pathway, such as the primary auditory pathway 308 and / or the reticular sensory pathway that carries sensory information.

[0065] The normal hearing system, also referred to as the normal auditory system 332, works like a conventional hearing system, allowing the listener to hear sounds by combining signals from the pinna, ear canal 256, and eardrum 252. Movement of the eardrum 252 causes movement of the middle ear bones 312, which in turn moves the inner ear 316, stimulating the auditory nerve to transmit the sound to the brain through the conventional auditory system 332.

[0066] The provided MAP headset 272 generates vibrations together with an audio signal source that forms two sound outputs to the brain. It should be noted that the linear movement against the sensitive part of the ear canal eustachian tube provides sound output to the user through the brand-new auditory system 330. Since the MAP headset 272 has multiple sound outputs, the second audio output will be transmitted to the brain through the normal auditory system 332, and the vibration output will be transmitted to the brain from the brand-new auditory system 330. The advantage of using the two auditory systems 330 - 332 is that it helps to improve the hearing of deaf and / or hearing-impaired people. Another advantage of using the MAP headset 272 that can play sounds through the two systems 330 - 332 is that it can create spatial audio or virtual reality audio in the application scenarios of music, movies, games, esports, virtual reality applications, live broadcast programs, and / or Metaverse-related programs. The MAP headset 272 can simultaneously generate different types of audio and vibration outputs, and these audio and vibration outputs combine signals to the brain through different auditory pathways, providing subwoofer effects, more audio reality, and / or live effects.

[0067] Figure 4A is a cross-sectional view showing the first driver 400 of the MAP headset containing various components in an embodiment of the present invention. The first driver, also known as the MEV driver 400, includes a yoke 4, a linear vertical vibrator 54, a housing 31, a diaphragm 32, and tuning paper 42. It should be noted that if Figure 4A add or remove one or more components (circuits or elements) from Figure 4A the basic concept of the exemplary embodiment of the present invention will not change.

[0068] In one embodiment, the MEV driver 400 includes an electromagnetic sound generator based on an electromagnetic mechanism. The electromagnetic sound generator is capable of generating a vibration output due to the movement of the diaphragm 32, and the diaphragm 32 moves air molecules for sound transmission. To fabricate or manufacture the MEV driver 400, the enameled voice coil 33 is rounded into a cylindrical tube, and the cylindrical tube is bonded or coupled to the symmetric position of the diaphragm 32. It is arranged that the diaphragm 32 affects the efficiency of the electromagnetic force induced on the diaphragm 32 to move air molecules to transmit sound. The material of the enameled voice coil 33 can be made of copper ("Cu"), silver ("Ag"), aluminum ("Al"), gold ("Au"), and / or made of a combination of Cu, Ag, Al, and / or alloyed with Au to obtain different acoustic effects of the electromagnetic sound generator. The length of the enameled voice coil 33 affects the DC resistance and / or impedance value.

[0069] The number of turns and thickness of the enameled voice coil 33 affect the resistance and impedance, which in turn affect the tonal balance and the frequency response curve between the electromagnetic sound generator and the mechanical sound generator. The enameled voice coil 33 is assembled at the central position, which helps to balance the diaphragm 32 of a cylindrical or any other shape. The diaphragm 32 is coupled or adhered at the housing 31 and is assembled or attached as a vibration node to the surround 44. The enameled voice coil 33 is located in the gap between the axis 36 and the weight unit 38. Note that the enameled voice coil 33 can affect the magnetic field generated by the magnet 35, which provides the induced electromagnetic force. The gap between the yoke 41 and the weight unit 38 is used to help the enameled voice coil 33 move up and down, affecting the induced electromagnetic force. According to the right-hand rule, the winding method and the number of turns of the enameled voice coil 33 can affect the electromagnetic force. The depth at which the enameled voice coil 33 enters the gap also affects the electromagnetic force. The thickness, shape, and material of the diaphragm 32 may also be important factors as it affects the resonance frequency and the frequency response curve, thus affecting the sound output.

[0070] In one embodiment, the MEV driver 400 is placed or configured near the back of the MPA earphone, and the audio driver is placed or configured near the sound-emitting hole of the MAP earphone. It should be noted that the distance between the MEV driver 400 and the audio driver is important as this distance affects the sound performance of the MEV driver 40. To provide multi-output surround sound, the MEV driver 400 includes a free yoke 4 and a linear vertical vibrator 54.

[0071] In one example, the configured MAP earphone incorporates different mechanisms into a single unit or earphone to save space. For example, first, the MAP earphone combines three different types of sound output mechanisms in one MEV driver 400, and subsequently, the combined sound is re-combined with the audio output from one or more audio drivers, and different audio and vibration outputs are sent simultaneously through different auditory pathways to obtain an audio illusion effect.

[0072] The configured mechanical sound generator activates the mechanical spring 50 of the vertical vibrator, generates a resonance frequency through vertical vibration, strikes or impacts the yoke 4 on the drum-shaped plate 39, generating mechanical audio. The linear vertical vibrator 54 is located at the bottom of the yoke 4, and the yoke 4 is fixed to the bottom of the yoke 41 by a pin armature lock 361. The linear vertical vibrator (54) consists of a yoke seat center plate 52 fixed to the yoke 4. The spring legs 53 are used to control the elasticity of the mechanical spring 50. It should be noted that the number, thickness, and design of the spring legs 53 affect the amplitude, response time, and damping performance of the vibration generated by the MEV driver 400. In one example, the spring legs 53 extend from the spring edge 55 fixed at the housing 31 to the central position of the mechanical spring hole 521.

[0073] The end of the spring leg (53) near the housing 31 is provided with a metal ring called the drum-shaped plate 39. A certain distance is provided between the lowest part of the bottom of the yoke 41, also called the pin armature lock 361, and the drum-shaped plate 39. In one example, the distance between the pin armature lock 361 and the drum-shaped plate 39 is fixed to ensure that the linear vertical vibrator 54 has an appropriate clearance so that the linear vertical vibrator 54 can reach the highest position correctly. The drum-shaped plate 39 is located below the bottom of the yoke 4. The printed circuit board 37 is used to connect the enameled voice coil 33 and the audio driver. The tuning paper 42 is located at the center of the printed circuit board 37 and is used to assist in tuning the frequency response of the MEV driver 400.

[0074] The advantage of using the MEV driver 400 that includes multiple different types of sound generators is to provide a compact headphone with extraordinary sound effects.

[0075] Figure 4B is a cross-sectional view showing various components of the electromagnetic sound generator in the first driver or MEV driver 402 of the MAP headphone in an embodiment of the present invention. Figure 402 shows the components of the electromagnetic sound generator 420. Figure 4C is a cross-sectional view showing the components of the mechanical sound generator 430 in the MEV driver 406 of the MAP headphone in an embodiment of the present invention. It should be noted that if Figure 4B or Figure 4C add or from Figure 4B or Figure 4C one or more components (circuits or elements) are deleted, the basic concept of the exemplary embodiment of the present invention will not change.

[0076] Figure 4D is a cross-sectional view showing the common components 450 used by the electromagnetic sound generator and the mechanical sound generator in the MEV driver of the MAP headphone in an embodiment of the present invention. In order to create an audio illusion in a compact MAP headphone, the MEV driver 408 uses various common parts or components 450 between the electromagnetic sound generator and the mechanical sound generator. In one embodiment, in response to an electronic audio input, the MEV driver 408 helps to generate at least one electromagnetic audio output, one mechanical audio output, and one vibration output simultaneously.

[0077] Refer to Figure 4A, in one example, the bottom of the yoke 4 is fixed through the mechanical spring hole 521, and the mechanical spring hole is locked by the pin armature lock 361 of the mechanical sound generator. At the central position of the yoke 41, the central axis 36 is surrounded by the magnet 35, and the magnet 35 provides a magnetic field for the electromagnetic acoustic generator. In one example, the central axis 36 is made of copper. One purpose of the central axis 36 is to support the magnet 35. The magnet 35 can be used together with a permanent magnet and includes a soft magnetic material that can effectively increase the magnetic force. At the bottom of the axis 36, the weight unit holder 34 of the extending structure holds the weight unit 38. An external weight unit 38 is added around the side of the central yoke 41 to enhance the momentum of the vibration force. The weight of the weight unit 38 is used to balance the elasticity and damping of the mechanical spring 50 to generate the momentum of the MEV driver 408. The function of the weight unit holder 34 is to extend the diameter of the yoke 4 so that the yoke 41 has a stable momentum vibration during vertical movement.

[0078] Figure 4E is a cross-sectional view showing the first driver or MEV driver 410 of the MAP earphone in a downward state during operation in an embodiment of the present invention. On the one hand, the MEV driver 410 generates three types of sound outputs. The first audio output is an electromagnetic audio output generated by the electromagnetic mechanism via the electromagnetic sound generator. The second audio output is a mechanical audio output generated by the mechanical mechanism via the mechanical sound generator. Refer to Figure 4A , the provided drum-shaped plate 39 impacts the rear of the yoke 4 to generate mechanical audio. The third mechanical output is a vibration output generated by the mechanical mechanism through the mechanical sound generator. In one example, the moving linear vertical vibrator 54 guides the movement of the housing 31 to generate a vibration output at the MEV driver 400. To generate the electromagnetic audio output, the mechanical audio output, and the vibration output, in one embodiment, the MEV driver 400 includes a yoke 4, a housing 31, a diaphragm 32, an enameled voice coil 33, a weight unit holder 34, a magnet 35, an axis 36, a pin armature lock 361, a printed circuit board 37, a weight unit 38, a drum-shaped plate 39, a yoke 41, a tuning paper 42, a terminal board 43, a hemming 44, a magnet cover 45, a mechanical spring 50, a dust cover 51, a yoke seat 52, a spring edge 55, a mechanical spring hole 521, a spring leg 53, and a linear vertical vibrator 54.

[0079] Refer to Figure 4A, the yoke 4 is located at the center of the MEV driver 400, and the MEV driver further includes a yoke 41 which comprises a shaft center 36, a magnet 35, a magnet cover 45, a pin armature lock 361, and an external weight unit holder 34 and a weight unit 38. The housing 31 is located at the plastic housing of the MEV driver 400 and is used to connect an electromagnetic sound generator and a mechanical sound generator so that the two generators work simultaneously. The diaphragm 32 is located at the top of the MEV driver 400 or 410 and is used to generate sound through molecular motion in response to the activity of the electromagnetic sound generator. The magnet wire voice coil 33 located below the diaphragm 32 can carry the current of the electroacoustic signal input from Figure 1 the connection cable 121 shown. The provided weight unit holder 34 extends from the yoke 41. It should be noted that the provided weight unit holder 34 holds and extends to the side of the yoke 41 and to the center of the yoke 4. The magnet 35 is located at the center of the shaft center 36 and / or around the shaft center 36. Based on the current generated by the electroacoustic signal input, the magnet 35 generates a magnetic field. The provided electromagnetic sound generator induces an electromagnetic force to help the diaphragm 32 move, thereby generating an electromagnetic audio output. The shaft center 36 is located at the central part of the yoke 4 and is used to support the magnet 35 fixing frame. The pin armature lock 361 is located at the bottom of the yoke 4 and is used to lock the yoke 4 in the yoke seat position 52 so as to generate vibration together with the linear vertical vibrator 54. The printed circuit board 37 is located at the bottom of the MEV driver 400 or 410 and is used to connect the electroacoustic signal input to the magnet wire voice coil 33 and the audio driver. The weight unit 38 is located at the end of the weight unit holder 34 and is used to provide weight around the center of the yoke 4. One function of the weight unit 38 is to increase momentum and stability when the yoke 4 moves up and down. The drum-shaped plate 39 is located at the side of the linear vertical vibrator 54 and is connected to the housing 31. One function of the drum-shaped plate 39 is to allow the bottom of the yoke ④ to hit an area to generate a mechanical audio output. The yoke 41 is located at the center of the MEV driver 410, and the yoke 41 includes a shaft center 36, a magnet 35, a magnet cover 45, and a pin armature lock 361. The tuning paper 42 is located at the bottom of the MEV driver 410 and is arranged to control the air flow entering the interior of the MEV driver 420 to adjust the audio characteristics. As Figure 5D shown, the terminal board 43 is located on the printed circuit board 37.

[0080] Figure 5A is a top view of a mechanical electromagnetic vibration ("MEV") driver 500 of a MAP headphone driver according to an embodiment of the present invention. Figure 5B is a top view of the yoke in the MEV driver 502 of the MAP headphone driver according to an embodiment of the present invention. Figure 5C is a top view of the linear vertical vibrator in the MEV driver 506 according to an embodiment of the present invention. It should be noted that if to Figure 5A , 5B, adding or removing one or more components (circuits or elements) to or from 5C will not change the basic concept of the exemplary embodiments of the present invention.

[0081] Figure 5A Shown is a bead 44 located on top of the MEV driver 500. The bead 44 surrounds the edge of the diaphragm 32 and is bonded at the housing 31. One function of the bead 44 is to protect the edge of the diaphragm 32. The magnet cover 45 is located on top of the magnet 35 at the center of the yoke 4. The magnet cover 45 is used to cover and protect the magnet 35. As Figure 5C shown, the mechanical spring 50 is located below the yoke 4 and is locked by the pin armature lock 361 and the mechanical spring hole 521. The mechanical spring 50 includes a yoke seat 52, spring legs 53, and a mechanical spring hole 521. The mechanical spring 50 has a drum-shaped plate 39, and the mechanical spring 50 is attached to the housing 31 at a relatively fixed position. One function of the mechanical spring 50 is to control the vertical vibration movement of the MAP earphone. As Figure 5D shown, the dust cover 51 is located at the bottom of the MEV driver 508 and is covered by the printed circuit board 37. The dust cover 51 is mounted on the side of the housing 31. The center hole is covered by the tuning paper 42. One function of the dust cover 51 is to prevent dust from entering the internal structure of the MEV driver 508. The yoke seat 52 is located on top of the linear vertical vibrator 54, which is the placement position of the yoke 4 and is locked by the pin armature lock 361 through the mechanical spring hole 521. The mechanical spring hole 521 is located at the center of the mechanical spring 50 and matches the size of the pin armature lock 361 for locking the yoke 4. The spring legs 53 are located at the mechanical spring 50 and extend to the yoke seat position 52, where the spring legs are used to extend the drum-shaped plate 39. One function of the spring legs 53 is to generate an elastic spring function for the yoke 4 and the linear vertical vibrator 54, promoting mechanical audio output and vibration output. The linear vertical vibrator 54 is located below the yoke 4, and the yoke 4 is locked by the pin armature lock 361 through the mechanical spring hole 521.

[0082] As Figure 4A shown, the linear vertical vibrator 54 is capable of generating two types of audio outputs. The first type of audio output is mechanical audio output, and the second type of audio output is vibration output. In one example, the linear vertical vibrator 54 strikes the drum-shaped plate 39 to produce mechanical sound, generating mechanical audio output. The movement of the yoke 4 generates vibration, promoting the movement of the linear vertical vibration 54 to form vibration output. It should be noted that the up and down vibration movement of the earplug will contact the sensitive part of the ear canal. The action of friction and / or contact with the sensitive part of the ear canal transmits signals to the brain, thus generating auditory hallucinations.

[0083] In one embodiment, the electromagnetic sound generator is coupled to the mechanical sound generator through the housing 31 and the yoke 4 as general components. It should be noted that it is important to let the two generators work simultaneously. To control theFigure 5C The number of spring legs 53 at an angle as shown is formed at the bottom of the mechanical spring hole 521. An external weight unit holder is used to fix the weight unit to increase the stability of the shaft 36 during vertical movement. As Figure 4A shown, the external weight unit holder 34 has a smaller diameter to provide clearance control during the vertical movement of the yoke 4. We will measure the measurable induced electromagnetic force generated by the electromagnetic acoustic generator (1). As Figure 5B shown, the elastic force of the mechanical spring 50 includes the mass of the yoke 4. Figure 5C shown, the elastic force of the mechanical spring 50 includes the mass of the yoke 4.

[0084] Figure 5D is a bottom view of an embodiment MEV driver 508 of the present invention. In operation, the electronic audio inputs of the left and right players of the MAP earphone are the same or substantially the same. When the electronic audio input is coupled to the terminal board 43 of the printed circuit board 37 in the MEV driver 508, the electronic audio input is fed to the enameled voice coil 33 and then transmitted to the audio driver. It should be noted that the frequency response after 1500 Hz can be tuned through the tuning paper 42.

[0085] As Figure 5A and Figure 5B shown, the diameter of the fixed weight unit 38 near the weight unit holder 34 is smaller than the diameter of the housing 31, thus forming a clearance for free movement in the vertical direction. It should be noted that non-vertical movement may result in energy loss. Figure 5C shows the thickness of the mechanical spring 50, the number of spring legs 53, the thickness of the spring legs 52, and the pattern of the mechanical spring 50 for controlling the spring force. It should be noted that longer and thinner spring legs 53 can provide additional elasticity for the MEV driver 506. The number of spring legs 53 also affects the balance of the shaft 36. In one example, the length of the spring legs 53 is configured to control the structural angle of the drum-shaped plate 39 as Figure 4A shown. Note that the distance between the spring legs 53 and the drum-shaped plate 39 will affect the sound output related to the mechanical hitting efficiency.

[0086] Figure 6A is a cross-sectional view showing the audio output generated by the electromagnetic sound generator in an embodiment MEV driver 600 of the present invention. The MEV driver 600 includes a diaphragm 32, an enameled voice coil 33, and a drum-shaped plate 39. The reaction flow shown by the dashed line 610 illustrates the movement of the diaphragm 32 during operation. It should be noted that if Figure 6A is added or removed from Figure 6AIf one or more components (circuits or elements) are removed from [the device], the basic concept of the exemplary embodiments of the present invention will not change. In one embodiment, an electronic audio input is fed to a printed circuit board 37, which in turn feeds the input signal to various components including one or more audio drivers.

[0087] Figure 6B is a cross-sectional view showing the audio output generated by the mechanical sound generator in a MEV driver 602 according to one embodiment of the present invention. The MEB driver 602 includes a diaphragm, an enameled voice coil, and a drum plate 39. The drum plate 39 is used to facilitate the generation of mechanical output. It should be noted that if one or more components (circuits or elements) are added to Figure 6B or removed from Figure 6B [the device], the basic concept of the exemplary embodiments of the present invention will not change.

[0088] Figure 7A is a schematic diagram showing the vibrational audio output generated by the mechanical sound generator in a MEV driver 700 according to one embodiment of the present invention. The MEV driver 700 includes a housing vibration member 710 and a mechanical spring member 712 for facilitating the generation of vibrational output. In one embodiment, the housing vibration member 710 includes Figure 4A the housing 31 and the bead 44 as shown. The mechanical spring member 712 includes the drum plate 39, Figure 4A the mechanical spring 50 as shown. It should be noted that if one or more components (circuits or elements) are added to Figure 7A or removed from Figure 7A [the device], the basic concept of the exemplary embodiments of the present invention will not change.

[0089] Figure 7B is a schematic diagram of a MEV driver 702 or 706 according to one embodiment of the present invention. The MEV driver 702 or 706 provides a reaction stream of electromagnetic audio output generated by an electromagnetic sound generator. The MEV driver 702 or 706 is capable of using any one of the three audio outputs generated by the electromagnetic mechanism produced by the electromagnetic sound generator. It should be noted that if one or more components (circuits or elements) are added to Figure 7B or removed from Figure 7B [the device], the basic concept of the exemplary embodiments of the present invention will not change.

[0090] In one embodiment, Figure 7BShows the movement of the diaphragm 32 as a reaction stream for electromagnetic audio output, as indicated by arrow 720. After the printed circuit board 37 receives an audio input signal, the magnetic field generated by the magnet guides the current in the same direction. The movement of the diaphragm 32 will move upward or downward according to the direction of the current. For example, when the current flows in the negative direction, the direction of the electromagnetic force may change to assist the direction of the current flow. It should be noted that the up and down movement of the diaphragm 32 can push air molecules to transmit sound as audio output. It should be noted that different frequencies of electronic audio input will generate different currents in the MAP earphone because different frequencies will generate different sound pressure levels.

[0091] Figure 8 is a schematic diagram showing the reaction stream of the mechanical sound generator in an embodiment of the present invention for generating mechanical audio output within the MEV driver 800 or 802 according to another embodiment of the present invention. Similar to Figure 6B the MEB driver 602 shown, the MEV driver 800 or 802 includes a diaphragm, an enameled voice coil, and a drum plate 39. The drum plate 39 is used to facilitate the generation of mechanical output. On the one hand, as Figure 4A shown, by hitting the drum plate 39 on the yoke 4, the movement of the housing 31 is pushed to generate mechanical output, and then mechanical and vibration sound outputs are generated. Note that the Motion of the diaphragm 32 causes vibration output and mechanical audio output. It should be noted that if one or more components (circuits or elements) are added to Figure 8 or deleted from Figure 8 , the basic concept of the exemplary embodiment of the present invention will not change.

[0092] Figure 9 is a cross-sectional view showing the reaction stream of the mechanical sound generator in an embodiment of the present invention for generating vibration audio output within the MEV driver 900 or 902 according to another embodiment of the present invention. It should be noted that the audio output starts from the movement of the diaphragm 32, and the movement causes an electromagnetic force to push the yoke 4, resulting in the vibration of the linear vertical vibrator 54, as Figure 4A shown. Mechanical audio output is generated until the falling yoke 4 hits the drum plate 39. It should be noted that if one or more components (circuits or elements) are added to Figure 9 or deleted from Figure 9 , the basic concept of the exemplary embodiment of the present invention will not change.

[0093] In one example, the MEV driver 900 or 902 uses a mechanical sound generator to facilitate the generation of vibration output. In operation, when the diaphragm 32 moves, an electromagnetic force is induced using an electromagnetic sound generator. For example, as Figure 4AAs shown, the movement of the diaphragm 32 will cause the enameled voice coil 33 to move under the magnetic field of the magnet 35, generating a reaction on the yoke 4. The yoke 4 is arranged as a free-floating mechanism, and the free-floating mechanism is locked to one side of the linear vertical vibrator 54 and the housing 31. When the diaphragm 32 vibrates up and down, it converts the movement of the yoke 4, the linear vertical vibrator 54, and the housing 31. The force acting on the housing 31 then provides the vibration output of the MAP earphone. It should be noted that the weight and structure of the yoke 4 are related to the response, vibration amplitude, and resonance frequency. The electromagnetic force causes the yoke 4 to rebound, counteracting the elasticity of the mechanical spring 50 in the linear vertical vibrator 54. The resonance frequency and vibration amplitude of the MAP earphone are related to the design and parameters of all components in the MAP earphone.

[0094] Figure 10A is a schematic diagram 1000 showing a single first MEV driver 1010 and a single audio device 1011 of the MAP earphone in an embodiment of the present invention. An embodiment of the present invention shows a single MEV driver 1010 and a MEV driver coupled to an audio driver 1011 in another embodiment of the present invention. It should be noted that if Figure 10A adding or deleting one or more components (circuits or elements) from Figure 10A , the basic concept of the exemplary embodiment of the present invention will not change.

[0095] The audio driver 1011, also known as the second audio device, can be constructed according to electromagnetic, piezoelectric, dynamic, mechanical, and / or armature-type audio devices. It should be noted that the MEV driver of the MAP earphone includes a free-floating yoke with an unfixed position, and during movement, some energy will be transferred to the mechanical spring. The frequency response curve of the MEV driver of the electromagnetic sound generator has a lower sound pressure level in the mid-frequency or high-frequency range. An important feature of the audio driver 1011 is to compensate for the lower sound pressure level in the mid-high frequency range.

[0096] Figure 10B is a schematic diagram 1002 showing multiple audio drivers 1012 of the MAP earphone according to another embodiment of the present invention in an embodiment of the present invention. Except for adding additional audio drivers to generate a full range of frequency characteristics to optimize the audio sound output, Figure 1002 is similar to Figure 1000, as Figure 10A shown. In one embodiment, the number of audio drivers used is a matching function related to the MEV driver and the application. It should be noted that the audio sound output by the audio driver occupies an important part or most of the total audio output. It should be noted that if Figure 10B adding or deleting one or more components (circuits or elements) from Figure 10B , the basic concept of the exemplary embodiment of the present invention will not change.

[0097] Figure 11 is a graph 1100 showing the amplitude curves of several vibration frequency bands of the audio output related to the MAP earphone according to another embodiment of the present invention in one embodiment of the present invention. Graph 1100 shows the amplitude curves of the vibration frequency bands of the MAP earphone, which contains information related to the response signal and tolerance. The amplitude curves of the vibration frequency bands combine the audio outputs of all drivers to form the audio frequency characteristics. As can be seen from Graph 1100, the frequency response curve shows an audio characteristic with a deep V-shaped sound pressure level drop around or before 200 Hertz ("Hz"). In one example, the deep V-shaped drop in the sound pressure level before 200 Hz comes from the energy transfer from the electromagnetic sound generator to the mechanical sound generator. The deep V-shaped drop frequency point below 200 Hz can be controlled according to the application and / or control requirements. It should be noted that the transferred energy causes the yoke and the linear vertical vibrator in the mechanical sound generator to move.

[0098] Figure 12 is a graph 1200 showing the vibration amplitude associated with the vibration audio output generated by the MAP earphone according to another embodiment of the present invention in one embodiment of the present invention. During operation, after the electronic audio input arrives, the electromagnetic sound system or the electromagnetic sound generator activates the diaphragm movement in response to the induced electromagnetic force. The movement of the diaphragm induces an electromagnetic force to be applied to the yoke, resulting in the movement of the linear vertical vibrator. Since the linear vertical vibrator is fixed to the housing, the movement causes the MAP earphone to produce a vibration output. Graph 1200 shows the total vibration energy of the MAP earphone around 80 - 200 Hz. It should be noted that when the input voltage is 0.126 Vrms, the minimum vibration amplitude is set at the resonance frequency of 20 mg. Fig. 1102 shows the minimum vibration amplitude of the MAP earphone, and the friction frequency should be between 80 - 200 Hz, as Figure 12 shown.

[0099] Figure 12is a graph showing the vibration response curve associated with the vibration audio output generated by the MAP earphone in accordance with another embodiment of the present invention in one embodiment of the present invention. FIG. 1200 shows the vibration frequency range between 80 - 200 Hz. FIG. 1200 also shows the maximum vibration amplitude of the MAP earphone at the resonance frequency (about 140 Hz). It should be noted that 140 Hz is approximately between 80 and 200 Hz. The vibration output is arranged to transmit the sound signal to the brain through the newly discovered auditory system using different frequencies and amplitudes. Different frequencies and amplitudes have different effects on the sensitive parts of the friction ear canal eustachian tube, transmitting audio of different frequencies. It should be noted that the vibration frequencies within 80 - 200 Hz include the subwoofer bass range, enhancing the bass effect. In one embodiment, the vibration amplitude is a factor in generating auditory hallucinations. For example, at an input of 0.126 root mean square voltage (“Vrms”), the minimum amplitude level of the vibration is 20 mg and varies according to different input voltages. The vibration will generate a friction process on the surface of the sensitive parts of the ear canal eustachian tube and transmit the auditory hallucination output (the effect of the vibration) of the audio signal to the brain, which is a secondary pathway of the auditory system.
