[0002] In the related art, noise reduction earphones can be divided into two categories: one is a headband that wraps around the ear, and the other is an in-ear earplug that is inserted into the ear. No matter the former or the latter, passive materials are used to absorb noise to create a sealed space, and then active noise reduction technology is used for noise reduction. However, the effect of both is weak. The headband has the advantage of reducing bone conduction, and has long battery life. The in-ear earplug has a small sound space, which is more conducive to active noise reduction. Currently, the noise reduction effects of in-ear earplugs and headbands are basically the same, but neither can achieve the mute effect that consumers understand. SUMMARY

[0027] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.
[0028] Headphones employing noise-canceling technology can deliver a more optimized sound experience. Current noise-canceling technologies include active and passive noise cancellation. Active noise cancellation works by generating a sound wave that is the opposite of the external noise, neutralizing it and achieving a noise reduction effect. Passive noise cancellation includes noise reduction at the sound source, noise reduction during propagation, and noise reduction at the ear. Passive noise cancellation at the ear primarily involves creating a closed space around the ear or using sound-insulating materials such as silicone earplugs to block external noise.
[0029] The working principle of noise reduction earphone, for passive noise reduction, due to the process of collection and operation, passive noise reduction earphone structure is simple and reliable, manufacturing threshold and technical content are relatively low; in addition, since the music itself is not disturbed, so the sound quality of passive noise reduction is better than that of active noise reduction earphone. Most importantly, passive noise reduction earphone does not need battery, can be used at any time. Therefore, this technology is widely applied to in-ear earphone, the current various in-ear earplug is a typical passive noise reduction earphone. Active noise reduction earphone requires higher, because of the most advanced electronic equipment to collect and process the noise around, so the noise reduction effect is better than that of passive noise reduction earphone. However, since the whole noise reduction process is an operation process, it may cause a certain degree of influence on the sound quality of earphone. In addition, active noise reduction earphone needs power supply.
[0030] According to the embodiments of the present disclosure, a kind of headset is provided, as shown in Figure 1 The headset includes: ear cover, cover is arranged at the outside of auricle;Ear cover microphone, for collecting ambient sound, is arranged at the outside of ear cover;First loudspeaker, for playing noise reduction sound corresponding to the ambient sound collected by ear cover microphone and / or playing audio, is arranged at the inside of ear cover;Wherein, when using, the inside of ear cover and auricle form containing space, for containing the part of in-ear earphone exposed to external auditory canal. Loudspeaker, also known as loudspeaker, is the electroacoustic device that converts electric energy into sound energy, and the principle of loudspeaker is that current passes through the coil in the magnetic circuit composed of magnet, generates driving force in up and down direction to make the vibration body vibrate, and then makes air vibrate to emit sound.
[0031] In one embodiment, the headset 20 includes an ear cover 21. Wherein, the ear cover 21 can cover the outside of the in-ear earphone 10. Specifically, the ear cover 21 is arranged at the auricle 51, and the ear cover 21 and the auricle 51 form a containing space for containing the part of the in-ear earphone 10 exposed to the external auditory canal 52. The ear cover 21 can cover the outside of the auricle 51 and be attached to the auricle 51. When the ear cover 21 is arranged at the auricle 51, the in-ear earphone 10 is covered inside.
[0032] The ear cover 21 of the headset 20 covers the outside of the in-ear earphone 10, which can play a role of keeping warm in winter, protecting the auricle 51 from cold and protecting the normal use of the in-ear earphone 10 in cold temperature. On the other hand, the ear cover 21 covers the outside of the in-ear earphone 10, which can also form the effect of sound box to improve the sound quality effect of the in-ear earphone 10. Finally, the ear cover 21 covers the outside of the in-ear earphone 10, which, by being attached to the auricle 51, forms a relatively closed environment from the auricle 51 to the entrance of the external auditory canal 52, reduces the interference of external noise and improves the effect of playing audio of the in-ear earphone 10.
[0033] In one embodiment, the headset 20 further comprises a first speaker 22, which is arranged inside the ear cover 21, i.e. the first speaker 22 is arranged at one end close to the auricle 51. The audio played through the first speaker 22 causes air vibration in the external auditory canal 52, reaches the tympanic membrane to cause mechanical movement of the auditory ossicles, the vibration of the stapes footplate causes movement of the vestibular window, and the energy is transmitted into the endolymph and perilymph in the cochlea, becomes liquid vibration, the hair cells on the basilar membrane move to produce bioelectric activity, the nerve impulse is transmitted through the auditory nerve, and the auditory cortex is reached to produce hearing.
[0034] In one embodiment, the headset 20 further comprises an ear cover microphone 23. The ear cover microphone 23 is arranged outside the ear cover 21 for collecting ambient sound. Specifically, an active noise reduction system must have a microphone, a processing chip and a speaker. The microphone is a device for collecting on-site ambient sound and transmitting it to the back-end equipment, which includes a microphone, a circuit board and a signal transmission cable, etc. The headset 20 is provided with the ear cover microphone 23, which is arranged outside the ear cover 21, so that the external environment sound can be collected. The microphone of the ear cover microphone 23 can sample the noise heard by the human ear, which is transmitted to the processing chip in the headset 20 through the circuit board and the signal transmission cable. The processing chip processes the noise collected by the ear cover microphone 23 through reverse and amplification, and then drives the first speaker 22 to play "anti-noise", wherein the played anti-noise is the noise reduction sound corresponding to the ambient sound collected by the ear cover microphone 23, which is used to eliminate the noise from the outside through the ear cover 21 into the human ear. As can be seen, the combination of the ear cover microphone 23 and the first speaker 22 of the headset 20 can make the headset 20 realize active noise reduction. It should be noted that when the headset 20 is used in combination with the in-ear earphone 10, the first speaker 22 of the headset 20 is only used to play the noise reduction sound corresponding to the ambient sound collected by the ear cover microphone 23, and no longer plays the audio selected by the user, and the audio selected by the user is played by the second speaker 11 of the in-ear earphone 10. When the headset 20 is used alone, the first speaker 22 of the headset 20 can play the noise reduction sound corresponding to the ambient sound collected by the ear cover microphone 23 and the audio selected by the user at the same time.
[0035] The headset 20 includes the first speaker 22 and the ear cover microphone 23, and the headset 20 is provided with the ear cover 21 which can cover the part of the in-ear earphone 10 exposed to the external ear canal 52. When the headset 20 is used alone, the first speaker 22 can play audio and noise reduction sound corresponding to the ambient sound collected by the ear cover microphone, forming active noise reduction. When the headset 20 is used in combination with the in-ear earphone 10, the first speaker 22 can play noise reduction sound corresponding to the ambient sound collected by the ear cover microphone. The in-ear earphone 10 is provided with an active noise reduction environment, reducing the interference of external noise. At the same time, the headset 20 can be detached, so that the in-ear earphone 10 is used alone or the headset 20 is used alone. When the headset 20 is used alone, the headset 20 has small pressure on the auricle 51. The headset 20 can be separated from the in-ear earphone 10 and used alone, so that the user can use different earphones in different environments. In a relatively noisy and irregular environment, the in-ear earphone 10 can be selected. The in-ear earphone 10 can partially block the medium and high frequency noise, but the noise reduction effect on low frequency noise is not obvious. In a relatively quiet and regular environment, the headset 20 can be selected. For example, active noise reduction can effectively reduce more than 80% of low frequency noise, and most of the noise in life is low frequency noise, such as the ambient noise in the scenes of buses, subways, high-speed rails, trains, cars, buses, airplanes, gyms, and bars.
[0036] In some embodiments, the headset 20 further includes an air inlet, an air blower 24, and an air pipe 30. The air inlet is arranged outside the ear cover 21; the air blower 24 is arranged in communication with the ear cover 21 and the air inlet; and the air pipe 30 is used to communicate the air blower 24 and the in-ear earphone 10. When the headset 20 is used in combination with the in-ear earphone 10, the air pipe 30 can make the air outside the ear cover 21 enter the in-ear earphone 10 and the external ear canal 52.
[0037] In some embodiments, the headset further includes a charging line 40. The charging line 40 is used to connect the battery 15 of the in-ear earphone 10 and the headset 20.
[0038] In the embodiment, the in-ear earphone 10 is provided with the battery 15, and the battery 15 can supply power to the in-ear earphone 10. When the in-ear earphone 10 is turned on in the active noise reduction mode, both the earphone microphone 12 and the processing chip need power supply.
[0039] The headset further comprises a charging wire 40, which can charge the battery 15 of the earphone 10. That is, one end of the charging wire 40 is connected to the earphone 10, and the other end of the charging wire 40 can be connected to a plug, or the other end of the charging wire 40 can be connected to the headset 20, that is, the earphone 10 can be charged by an external charging device, or when the earphone 10 is used in combination with the headset 20, the earphone 10 can be charged by the headset 20.
[0040] In addition, when the headset 20 charges the battery 15 of the earphone 10, the two ends of the charging wire 40 are respectively connected to the headset 20 and the battery 15 of the earphone 10, and the two ends of the charging wire 40 can be separated from the headset 20 and the earphone 10, which is convenient for the comfort and aesthetics when the headset 20 and the earphone 10 are used separately. At this time, the headset 20 can be a wireless headset or a wired headset. Further, when the earphone 10 is low in power, the headset 20 used in combination can be used as a power source to charge the earphone 10. After charging the earphone 10, the earphone 10 can be used alone, or the headset 20 can be used to charge the earphone 10 while the headset 20 and the earphone 10 are used in combination.
[0041] In some embodiments, the headset 20 further comprises a skeleton 25. The two ends of the skeleton 25 are respectively connected to one ear cover 21, and the side of the skeleton 25 facing the head is provided with a support body 26, which is used to avoid the contact between the skeleton 25 and the head.
[0042] As shown in FIG. 1, the earphone 10 comprises a battery 15, a sound collecting device 11, a sound processing device 12, a sound emitting device 13, and a sound guide device 14. Figure 2As shown, the two ear covers 21 of the headset 20 are often provided with a framework 25 for connection. The two ends of the framework 25 are connected to one ear cover 21 respectively. When wearing the headset 20, the framework 25 is in contact with the head 50 of the user. When not wearing the headset 20, the framework 25 can be placed on the neck of the user. Therefore, the framework 25 can prevent the ear cover 21 from falling off due to gravity and being damaged or lost, or prevent the ear cover 21 from falling off due to strong vibration during exercise. In addition, the framework 25 is in contact with the head 50 of the user, so the framework 25 is arc-shaped. The bending radius of the framework 25 corresponds to the radius of the head 50 or the radius of the neck, which can ensure the comfort of the user. The framework 25 can be provided in a flat structure, so that the contact area between the headset 20 and the head 50 is large and the pressure is small. The framework 25 can be made of polystyrene, polyvinyl chloride or polytetrafluoroethylene. At the same time, the framework 25 has elasticity and clamping force. When the user uses the headset 20, the clamping force of the framework 25 makes the ear cover 21 at both ends of the framework 25 fit the auricle 51 of the ear more closely, so that a more closed space is formed between the ear cover 21 and the auricle 51, the passive noise reduction effect is better, and the user's experience is improved.
[0043] As shown in the drawings, Figure 2 A support body 26 is provided on the side of the framework 25 facing the head 50 of the user. When the user wears the headset 20, the support body 26 can keep the framework 25 at a certain distance from the head 50 of the user without contacting. On the one hand, it can adapt to different head shapes of users, making it more fit and stable. On the other hand, the support body 26 keeps a certain distance between the framework 25 and the head 50, which can prevent the framework 25 from being pressed and collapsed when it is in contact with the head 50, solving the problem of damaging the hairstyle caused by the framework 25 pressing the hair. In addition, when the user exercises while wearing the headset 20, the spacing distance between the framework 25 and the head 50 can also help dissipate heat, and can also prevent the framework 25 from being eroded by sweat and the like from the head 50 of the user, effectively preventing sweat, thereby prolonging the service life of the framework 25.
[0044] In addition, the side of the support body 26 in contact with the head 50 can be arc-shaped and correspond to the radius of the head 50. The support body 26 can be fixedly provided on the framework 25 or detachably provided on the framework 25. The user can also adjust the length of the support body 26 according to the intensity of the exercise or the temperature of the use, that is, adjust the spacing distance between the framework 25 and the head 50 of the user. By adjusting the length of the support body 26, it can be suitable for different head 50 of the user. Specifically, the user adjusts the length of the support body 26 according to the size or length of the head 50, so that the head 50 can contact the headset 20 through three points, including two ear covers 21 and one support body 26, so that the headset 20 is more comfortable and stable to wear.
[0045] In some embodiments, the support body 26 comprises a plurality of support columns which are arrayed at intervals in the framework 25. As shown in Figure 5 each support column has one end arranged at the side of the framework 25 close to the head 50, and the other end is provided with an arc-shaped ball. When the arc-shaped ball is in contact with the head 50 of the user, it avoids the support column scratching the head 50 of the user. The support body 26 comprises a plurality of support columns which can increase the ventilation environment and save materials. In addition, a vibration motor can be arranged in each support column to vibrate the support column, and the vibration of the plurality of support columns in cooperation with the arc-shaped balls at the ends of the plurality of support columns in contact with the head 50 can massage the scalp of the user. In addition, as shown in Figure 4 the lengths of the plurality of support columns are not the same, and the ends of the plurality of support columns close to the head 50 form arc surfaces corresponding to the head 50. This can improve the comfort of the user.
[0046] In some embodiments, the headphone 20 further comprises an ear cover sealing ring 27 arranged at the end of the shell of the headphone 20 close to the ear. Specifically, as shown in Figure 1 and Figure 4 the ear cover sealing ring 27 has a filtering effect on sound. When the ear cover 21 is in contact with the auricle 51, there will be a gap between the ear cover 21 and the auricle 51 due to the fact that the auricle 51 of a human ear is not a flat surface, so that external noise enters the inside of the ear cover 21 through the gap. The ear cover sealing ring 27 arranged at the end of the headphone 20 close to the ear is soft and can be in contact with the skin of the auricle 51 to isolate a large amount of external noise and improve the sound quality experience.
[0047] According to embodiments of the present disclosure, a multi-layer noise reduction earphone assembly is provided, as shown in Figure 3 which comprises an in-ear earphone 10 and a headphone 20. The in-ear earphone 10 is located in the accommodating space formed by the headphone 20 and the auricle. As shown in Figure 3 the in-ear earphone 10 comprises a second speaker 11 arranged at the in-ear end of the in-ear earphone 10 for playing audio. When the headphone 20 is used in combination with the in-ear earphone 10, the ear cover 21 of the headphone 20 is in contact with the auricle 51 of the human ear, and has a physical noise reduction function, i.e. passive noise reduction. The speaker supports the in-ear earphone 10 to realize the audio output function. The second speaker 11 is inserted into the external auditory canal 52 of the user, and the audio played by the second speaker 11 causes the air in the external auditory canal 52 to vibrate, reaches the tympanic membrane to cause mechanical movement of the auditory ossicles, the vibration of the stapes footplate causes movement of the vestibular window, and the energy is transmitted into the endolymph and perilymph in the cochlea to become liquid vibration, the movement of the hair cells on the basilar membrane produces bioelectric activity, the nerve impulse is transmitted through the auditory nerve and the auditory nerve pathway to the auditory cortex center to produce hearing.
[0048] The ear cover microphone 23 of the headphone 20 can be combined with the first speaker 22 to have the function of active noise reduction. Therefore, the combination of the ear cover 21, the ear cover microphone 23 and the first speaker 22 of the headphone 20 can simultaneously realize passive noise reduction and active noise reduction. The passive noise reduction of the headphone 20 physically provides an enclosed environment for the in-ear earphone 10 and hinders the interference of external noise. The active noise reduction of the headphone 20 filters part of the noise in the environment in advance for the in-ear earphone 10. The passive noise reduction and the active noise reduction of the headphone 20 are combined with the passive noise reduction of the in-ear earphone 10 to solve the problem of insufficient noise reduction through multi-layer superposition, and the noise reduction effect is greatly improved. When the headphone 20 is used alone, the passive noise reduction and the active noise reduction of the headphone 20 itself can not only keep away from the disturbance of noise, but also adjust the mood through the earphone, and isolate the damage of noise to the ear drum and the eardrum.
[0049] In some embodiments, the in-ear earphone 10 further comprises an earphone microphone 12. Specifically, the working principle of the earphone microphone 12 is the same as that of the ear cover microphone 23. The earphone microphone 12 can be used to collect environmental sound; the second speaker 11 can also be used to play noise reduction sound corresponding to the environmental sound collected by the earphone microphone 12. The in-ear earphone 10 can include two modes, an active noise reduction mode and a passive noise reduction mode, when the in-ear earphone 10 is in the passive noise reduction mode, that is, the active noise reduction mode is closed. When the in-ear earphone 10 is in the active noise reduction mode, that is, the active noise reduction mode is opened. The earphone microphone 12 of the in-ear earphone 10 is located away from the in-ear end.
[0050] When the in-ear earphone 10 is used alone, the earphone microphone 12 of the in-ear earphone 10 can collect the sound of the external environment, and the microphone of the earphone microphone 12 can sample the noise heard by the human ear, and transmit it to the processing chip in the in-ear earphone 10 through the circuit board and signal transmission cable of the earphone microphone 12. The processing chip processes the noise collected by the earphone microphone 12 through reverse and amplification, and then drives the second speaker 11 to play "anti-noise". Playing anti-noise means playing noise reduction sound corresponding to the environmental sound collected by the ear cover microphone 23, which is used to eliminate the noise transmitted to the human ear through the ear cover 21. When the in-ear earphone 10 is used in combination with the headphone 20, the in-ear earphone 10 can open the active noise reduction mode, and the headphone 20 can also open the active noise reduction mode; or the in-ear earphone 10 opens the active noise reduction mode, and the headphone 20 adopts the passive noise reduction mode; or the in-ear earphone 10 adopts the passive noise reduction mode, and the headphone 20 opens the active noise reduction mode; or the in-ear earphone 10 and the headphone 20 simultaneously adopt the passive noise reduction mode.
[0051] When the in-ear earphone 10 and the headphone 20 are used in combination and both are turned on the active noise reduction mode, the working process of the headphone 20 and the in-ear earphone 10 is as follows:
[0052] The ear cover microphone 23 outside the ear cover 21 of the headphone 20 collects the sound of the external environment of the ear cover 21, and after being processed by the processing chip of the headphone 20, the sound opposite in phase to the noise collected by the ear cover microphone 23 is played by the first loudspeaker 22 to neutralize the noise of the external environment. The in-ear earphone 10 is wrapped in the closed space formed by the headphone 20 and the auricle 51, so the earphone microphone 12 is used to collect the sound in the closed space, wherein the sound in the closed space at this time is the sound after the active noise reduction system of the headphone 20 neutralizes the noise of the external environment, which is processed by the processing chip of the in-ear earphone 10, and the sound opposite in phase to the noise collected by the earphone microphone 12 is played by the second loudspeaker 11 to neutralize the sound in the external environment and the closed space. In addition, the second loudspeaker 11 also plays the audio sound selected by the user to be listened to. The in-ear earphone 10 and the headphone 20 both have passive noise reduction function, and after both are turned on the active noise reduction, the four-layer noise reduction of the active noise reduction and passive noise reduction of the headphone 20 and the active noise reduction and passive noise reduction of the in-ear earphone 10 is realized.
[0053] When the in-ear earphone 10 is turned on the active noise reduction and the headphone 20 adopts the passive noise reduction, the noise reduction process of the headphone 20 and the in-ear earphone 10 is as follows:
[0054] The noise in the closed space formed by the headphone 20 and the auricle 51 is filtered by the passive noise reduction material of the headphone 20, the earphone microphone 12 of the in-ear earphone 10 collects the sound in the closed space at this time, and after being processed by the processing chip of the in-ear earphone 10, the sound opposite in phase to the sound collected by the earphone microphone 12 is played by the second loudspeaker 11 of the in-ear earphone 10, and the second loudspeaker 11 also plays the audio sound selected by the user to be listened to. At this time, the three-layer noise reduction of the passive noise reduction of the headphone 20 and the active noise reduction and passive noise reduction of the in-ear earphone 10 is realized.
[0055] When the in-ear earphone 10 adopts the passive noise reduction and the headphone 20 is turned on the active noise reduction, the noise reduction process of the headphone 20 and the in-ear earphone 10 is as follows:
[0056] The ear cover sound pick-up 23 of the headphone 20 stimulates the sound of the external environment, and after processing by the processing chip of the headphone 20, the noise reduction sound corresponding to the environment sound collected by the ear cover sound pick-up 23 is played by the second sound pick-up, so as to eliminate the noise from the external environment entering the human ear through the ear cover 21. Then, passive noise reduction is realized by the passive material of the in-ear earphone 10, and the user-selected audio sound to be listened to is played by the second loudspeaker 11 of the in-ear earphone 10. At this time, three-layer noise reduction is realized by the passive noise reduction and the active noise reduction of the headphone 20 and the passive noise reduction of the in-ear earphone 10.
[0057] It should be noted that the in-ear earphone 10 adopts the active noise reduction mode or the passive noise reduction mode, and the headphone 20 adopts the active noise reduction mode or the passive noise reduction mode, which can be arbitrarily selected by the user according to the use environment, and both can realize multi-layer noise reduction, which is not limited here. The above is described by specific embodiments, and is not used to limit the protection scope of the present application.
[0058] In some embodiments, the in-ear earphone 10 and the headphone 20 are detachably connected. As known from the above, the in-ear earphone 10 can be a passive noise reduction earphone, or an earphone combining active noise reduction and passive noise reduction. The headphone 20 is the same, and can also be a passive noise reduction earphone, or an earphone combining active noise reduction and passive noise reduction. As mentioned above, the in-ear earphone 10 and the headphone 20 can be used as earphones alone, or can be used together. When used together, the headphone 20 has a skeleton, and one ear cover 21 can be connected to each end of the skeleton, and the friction force is generated by the skeleton and the clamping force of the two ear covers 21 on the auricle 51 to be fixed at the auricle 51; and the in-ear end of the in-ear earphone 10 is inserted into the external auditory canal 52 for fixation. Therefore, the in-ear earphone 10 and the headphone 20 can not have a connecting piece.
[0059] The detachable connection of the in-ear earphone 10 and the headphone 20 means that the in-ear earphone 10 and the headphone 20 can be connected together by a connecting piece. The connecting piece can be a soft connecting piece or a fixed connecting piece. The soft connecting piece can be a soft connecting line, and the fixed connecting piece can be a buckle connection. The connecting piece allows the in-ear earphone 10 and the headphone 20 to be detachably connected, so that when the in-ear earphone 10 and the headphone 20 are used together, they can be integrated, avoiding the loss of one of them affecting the noise reduction effect. In addition, the connecting piece is also convenient for storage and organization, and when the multi-layer noise reduction earphone assembly is not used, the two earphones can be stored together, so as not to be placed separately and cause the loss of the headphone 20 or the in-ear earphone 10.
[0060] In some embodiments, the earphone 10 further comprises an air inlet, an air duct and an air outlet 13. The air inlet is arranged at the rear end opposite to the ear insertion end, and the air outlet 13 is arranged at the ear insertion end, and the air duct is in communication with the air inlet and the air outlet 13.
[0061] The air inlet adjusts the air pressure in the external auditory canal 52. Sound is transmitted to the human ear by sound waves. When the earphone 10 is inserted into the external auditory canal 52, the environment in the external auditory canal 52 becomes a closed environment. The sound heard by the ear can be somewhat muffled, and the sound quality can be changed. A small hole (i.e. the air outlet 13) is opened on the side of the earphone 10, which can balance the air pressure inside and outside the external auditory canal 52, thereby ensuring the sound quality and protecting the hearing of the ear.
[0062] The earphone body of the earphone 10 is provided with the air inlet and the air outlet 13, and the air duct is in communication between the air inlet and the air outlet 13. The air inlet and the air outlet 13 are both located on the earphone body of the earphone 10. The air outlet 13 is located at the ear insertion end of the earphone 10, and when the earphone 10 is inserted into the external auditory canal 52, the air outlet 13 also enters the external auditory canal 52. The air outlet 13 is in communication with the external auditory canal 52, thereby adjusting the air pressure in the external auditory canal 52. The air inlet is located at the rear end of the earphone body of the earphone 10 away from the ear insertion end, and the air inlet is in communication with the air outside the earphone 10, thereby allowing the external air to enter the air inlet. The air duct for communication between the air inlet and the air outlet 13 is located in the earphone body of the earphone 10. As known from the above, the air inlet is in communication with the external air, the air outlet 13 is in communication with the air in the external auditory canal 52, and the air duct is in communication between the air inlet and the air outlet 13, thereby allowing the air in the external auditory canal 52 to be in communication with the air outside the earphone 10, and balancing the air pressure in the external auditory canal 52. When the earphone 10 is used alone, the air outside the earphone 10 enters the air inlet and is in communication with the air in the external auditory canal 52 through the air duct and the air outlet 13, thereby balancing the air pressure in the external auditory canal 52.
[0063] When the in-ear earphone 10 is used in combination with the headphone 20, the headphone 20 is provided with an air inlet, which is arranged outside the ear cover 21, so that the air outside the ear cover 21 enters the air inlet, and the air inlet is in communication with the air inlet of the in-ear earphone 10 through the air pipe 30, so that the air outside the ear cover 21 of the headphone 20 enters the air inlet, passes through the air pipe 30, and then enters the air inlet of the in-ear earphone 10, and then passes through the air duct and the air outlet 13 of the in-ear earphone 10 to communicate with the air in the external auditory canal 52, so as to balance the air pressure in the external auditory canal 52. In addition, when the in-ear earphone 10 is used in combination with the headphone 20, an air blower 24 can be arranged at the air inlet, so that the air outside the ear cover 21 of the headphone 20 is actively sent into the air inlet through the rotation of the air blower 24, which can avoid the problem that the air outside the ear cover 21 cannot communicate with the air in the external auditory canal 52 due to the length or pressure of the air pipe 30, and can also accelerate the air circulation between the air outside the ear cover 21 and the air in the external auditory canal 52, so as to actively send air and better solve the problem of heat in the in-ear earphone 10.
[0064] In addition, the air pipe 30 is detachably arranged between the air inlet and the air inlet. When the headphone 20 and the in-ear earphone 10 are separated and used independently, the two ends of the air pipe 30 can be detached from the air inlet of the headphone 20 and the air inlet of the in-ear earphone 10 respectively, so as to avoid affecting the appearance and comfort when the headphone 20 and the in-ear earphone 10 are used independently. In addition, the air pipe 30 can be made of soft material, or can be made of hard material. When the air pipe 30 is made of soft material, it can be arbitrarily bent in the closed space formed by the inside of the ear cover 21 and the auricle 51 according to the use environment. When the air pipe 30 is made of hard material, that is, the shape and structure of the air pipe 30 are fixed and cannot be bent or changed, the phenomenon that the air pipe 30 cannot be connected due to external force factors other than human force can be avoided.
[0065] In some embodiments, the in-ear earphone 10 further comprises an earplug skin 14. The earplug skin 14 is arranged at the in-ear end of the in-ear earphone 10; and the air outlet 13 is located at the second loudspeaker 11.
[0066] Specifically, the in-ear end of the in-ear earphone 10 is inserted into the external auditory canal 52 of the ear, and the second loudspeaker 11 is arranged at the in-ear end, so that the audio played by the second loudspeaker 11 can be received by the human ear. An air duct is arranged outside the in-ear end of the in-ear earphone 10 and surrounds the in-ear end, so that the air in the external auditory canal 52 can enter the air duct through the air outlet 13 of the in-ear earphone 10.
[0067] The earplug head 14 can be made of silicone material. Because the sound contact area of the in-ear earphone 10 is small, the pressure on the inner ear is large. The earplug head 14 arranged at the in-ear end of the in-ear earphone 10 can reduce part of the pressure. The earplug head 14 is designed according to ergonomics and is processed by mold pressing using environmentally friendly soft silicone material. The biggest feature of the earplug head 14 is that it is convenient and comfortable to wear, and it eliminates the damage of the in-ear end of the in-ear earphone 10 to the ear, solves the pain of long-term wearing of the earphone, and makes the movement more random. In addition, the earplug head 14 also has the function of preventing the earphone from falling off due to strong vibration during exercise, and can effectively protect the earphone wire from corrosion such as sweat, effectively prevent sweat, thereby prolonging the service life of the earphone.
[0068] From the above, it can be seen that the exhaust port 13 is arranged at the in-ear end, so that when the in-ear end of the in-ear earphone 10 is inserted into the external auditory canal 52, the exhaust port 13 is in communication with the external auditory canal 52. The second loudspeaker 11 is also arranged at the in-ear end, so the exhaust port 13 is also arranged at the second loudspeaker 11. The exhaust port 13 can balance the air pressure inside and outside the external auditory canal 52, thereby ensuring the sound quality and protecting the hearing of the ear.
[0069] In some embodiments, the in-ear earphone 10 is a wireless earphone, and / or the headphone 20 is a wireless earphone. In this embodiment, the in-ear earphone 10 is a wireless earphone, which can be connected with an electronic terminal device through a wireless connection mode such as Bluetooth or WiFi, and receive signals transmitted by the electronic terminal device. The headphone 20 can be a wired earphone or a wireless earphone. The working principle of the headphone 20 as a wireless earphone is the same as that of the in-ear earphone 10, which will not be described here.
[0070] In summary, the advantages of the present application include: 1. The problem of insufficient noise reduction is solved by multi-layer superimposed active noise reduction, and the noise reduction effect is greatly improved; 2. The internal stuffy problem caused by the sealing of the multi-layer noise reduction earphone assembly is solved by active air supply; 3. The problem of hair being pressed down by the earphone is solved by the three-dimensional contact support method, which does not affect the hairstyle; 4. The combination of the headphone 20 and the in-ear earphone 10 makes the in-ear earphone 10 have enough power to last longer, and improves the endurance of the in-ear earphone 10.
