This not only saves people's time for going to the hospital for detection, but also can improve the frequency of people's health detection, obtain the health index of the physical condition in time, and take corresponding measures in time. In the related art, since the open earphone does not extend into the user's ear canal and has less contact with the user's ear, there are great technical difficulties in realizing the function of health detection.

[0025] With the improvement of China's economic level, people's health awareness has gradually increased, and the frequency of health checks has also gradually increased. In order to meet people's health needs, various health diagnosis devices have emerged in an endless stream, enabling people to check their own health conditions without going to the hospital.

[0026] In addition, with the development of society, various electronic devices have emerged continuously, and headphones have become a necessity in people's lives, almost accompanying people's lives all the time. Therefore, using headphones to detect people's health index in real time will surely become a new development trend. This not only saves people's time for going to the hospital for detection, but also can increase the frequency of people's health detection, obtain the health index of the physical condition in a timely manner, and take corresponding measures in a timely manner.

[0027] However, current headphones detect information such as the human pulse and temperature through sensors and are generally used for automatic control of headphone volume and external electronic devices of the headphones, and are rarely used for health index detection. Some health detection headphones are used to detect the human condition, but generally they are designed for a single health index and detect the health index by measuring the temperature around the ears. These measurements of health indexes far from meet people's health detection needs. In order to check various health indexes and obtain a comprehensive physical condition, people often still need to go to the hospital for regular checks or purchase different detection devices for measuring health indexes, which is time-consuming and laborious.

[0028] In the related art, due to the design of open headphones, which do not extend into the user's ear canal, they are generally more comfortable than closed headphones because they allow air circulation, reducing heat and humidity in the ears. Therefore, open headphones are suitable for long-term wearing applications and can be used in many scenarios. However, since they do not extend into the user's ear canal and have less contact with the user's ears, open headphones lack the function of health detection.

[0029] To solve the above problems, please refer to Figures 1 to 3 , this application proposes an open headphone 1, which can include a clip-on headphone 100 and a hook-on headphone 200. The clip-on headphone 100 adopts a clip structure, and generates a clamping force through the deformation of the clip structure, so that the headphone can be worn on the user's ear in the form of clamping the user's ear. The hook-on headphone 200 is hung between the back side of the user's ear and the head through a hook structure to wear the headphone on the user's ear.

[0030] In the embodiment of this application, the open headphone 1 includes a sound generating component 10, a fixing component 20, and a sensor 30. The fixing component 20 is connected to the sound generating component 10. The fixing component 20 includes a detection area, which is located on the back of the user's auricle when the open headphone 1 is in a worn state; the sensor 30 is arranged on the fixing component 20 and located in the detection area. The sensor 30 is arranged close to the back of the user's auricle when the open headphone 1 is in a worn state, and is used for collecting the user's biological information.

[0031] In the worn state, the sound generating component 10 is located in the concha cavity or partially located in the concha cavity, and the fixing component 20 is located on the back of the auricle, such as behind the helix or behind the antitragus. The sound generating component 10 and the fixing component 20 cooperate with each other to clamp, so as to stably wear the open headphone 1 on the user's ear. By arranging the sensor 30 on the fixing component 20, during the wearing process, due to the joint clamping of the sound generating component 10 and the fixing component 20, it is ensured that the open headphone 1 does not loosen during wearing, thereby improving the reliability of the open headphone 1 for health detection of the user during wearing, and also avoiding the influence of the ear tip on the sound generating component 10 on the detection, effectively ensuring the usability of the sensor 30, and improving the accuracy of the sensor 30 for collecting the user's biological information. At the same time, the sensor 30 is arranged on the back of the user's auricle, that is, on the back side of the ear, and can be spaced from the sound generating component 10 worn on the front side of the ear, which can reduce the volume and weight of the sound generating component 10, thereby improving the wearing comfort, and can also avoid the sensor 30 being arranged on the sound generating component 10 and stacked with the components of the sound generating component 10, causing the shape of the front side of the ear to be bloated when the open headphone 1 is worn, thus achieving the effect of beautiful shape.

[0032] The detection area of the fixing component 20 is arranged opposite to the antitragus of the user when the open earphone 1 is in the wearing state. The sensor 30 is arranged on the fixing component 20 and located in the detection area, so that the contact area between the sensor 30 and the back of the user's auricle can be increased, so as to better realize the detection on the back of the user's auricle and improve the detection accuracy of the sensor 30. It can be understood that when the sensor 30 is in the wearing state, it may not be in contact with the back of the user's auricle, and the detection of the sensor 30 on the back of the user's auricle can still be realized. Moreover, the non-contact design can further improve the comfort of the user during wearing.

[0033] The sensor 30 is arranged close to the postauricular attachment point of the user. The postauricular attachment point generally refers to the part where the posterior side of the ear is connected to the skull, that is, the place where the posterior side of the ear is joined to the skull. Specifically, the ear is composed of three parts: the outer ear, the middle ear and the inner ear. Among them, the outer ear includes the auricle and the external auditory canal. The auricle is a cartilaginous structure protruding on both sides of the head, covered with skin and a small amount of muscle. Its main function is to collect sound waves and direct them to the ear canal. The base of the auricle is connected to the squamous part of the temporal bone of the skull, and this connection point is the postauricular attachment point. The postauricular attachment point specifically includes the mastoid area and the postauricular sulcus. The mastoid area is the convex part below the auricle, which is a part of the temporal bone and also the posterior wall of the middle ear tympanic cavity; the postauricular sulcus is the depression between the auricle and the skull, which is the boundary where the auricle is connected to the skin and soft tissues of the head. When the sensor 30 is arranged close to the back of the user's auricle in the wearing state, the biological information at the postauricular attachment point of the user can be collected, and corresponding health detection can be carried out to realize the health monitoring function.

[0034] Please refer to Figure 5 and Figure 6 , Figure 5 FIG. is a schematic diagram of the position of the earphone on the user's ear when the earphone is in the wearing state in the prior art. The earphone is worn on the front side of the ear and in contact with the front side of the ear. Then, the detection device on the earphone detects the meridians in the concha cavity. However, when the earphone is worn in the concha cavity and blocks the ear canal opening, it will cause discomfort to the user's ear after long-term use. Therefore, it is difficult to continuously collect the biological information of the user.

[0035] Figure 6This is a schematic diagram of the position where the open earphone 1 in the embodiment of the present application is in a worn state and contacts the back of the user's auricle. At this time, the sensor 30 of the open earphone 1 is arranged close to the back of the user's antitragus and close to the attachment point behind the user's ear. Thus, the sensor 30 can detect the corresponding health data of the posterior auricular artery through the contact detection with the attachment point behind the ear. The posterior auricular artery originates from the distal end of the external carotid artery near the end, at the distal end of the origin of the occipital artery, and runs backward. The posterior auricular artery mainly forms an anastomosis with the anterior auricular artery, a branch of the superficial temporal artery, at the auricle of the ear, jointly participating in the blood supply of the auricle, mainly supplying most of the auricle and the skin of the occipital region, and also giving off the stylomastoid artery to supply the middle ear and the facial nerve.

[0036] The biological information of the user collected by the sensor 30 includes at least one of heart rate, blood pressure, blood oxygen, and brain wave information, which are all important indicators of human health. And, one or more sensors 30 can be provided, and the sensor 30 can be at least one of an electrode type sensor, a PPG sensor, or an ECG sensor.

[0037] An electrode type sensor is a sensor that measures electrical signals, and its working principle is based on the potential difference between electrodes. Usually, an electrode type sensor consists of at least a pair of dry electrodes, and these dry electrodes can be in direct or indirect contact with the measurement object. A dry electrode refers to an electrode that does not need to be used in combination with a conductive paste, and is mainly used to measure bioelectric potential signals such as electrocardiogram, electroencephalogram, and electromyogram signals. Since skin preparation and application of conductive paste are not required, dry electrodes are very suitable for the needs of future health monitoring, rehabilitation, disease diagnosis and treatment, and brain-computer interface detection and human-computer interaction systems.

[0038] According to the contact method between the electrode and the organism, dry electrodes can be divided into capacitive dry electrodes and impedance dry electrodes. A capacitive dry electrode means that there is an insulating film isolating the conductor as the electrode and the organism, forming a capacitive coupling method.

[0039] The biggest advantage of a capacitive electrode is that it can record bioelectric potential signals through clothing. The disadvantage is that the signal-to-noise ratio is relatively small and it is easily interfered. Therefore, it often requires a relatively large electrode area to measure signals with relatively large intensities (such as the monitoring of electrocardiogram signals).

[0040] Like impedance-coupled and ordinary wet electrodes, it is necessary to attach the electrodes to the body surface to couple the bioelectric potential signal. According to the structure of the electrodes, impedance dry electrodes are mainly divided into microstructured surface dry electrodes and flat dry electrodes. Microstructured surface dry electrodes mainly refer to dry electrodes that contact the skin through their surface micro-nano structures. Usually, nano- or micro-scale pillar arrays can penetrate the stratum corneum of the skin and contact the inner skin tissue. Since the stratum corneum with the largest contact impedance is avoided, a lower electrode-skin interface impedance can be obtained. The millimeter- or centimeter-scale pillar array dry electrodes can effectively penetrate the hair due to their large size and can be used in the hairy area. Moreover, the millimeter- or centimeter-scale pillar array dry electrodes have the advantages of non-invasiveness and low preparation cost. For example, they can be processed and prepared by methods such as molding and 3D printing. The embodiments of the present application do not limit the type of dry electrodes used in the electrode-type sensor.

[0041] The PPG sensor uses photoplethysmography (PPG) based on Lambert-Beer's law to monitor the corresponding physical health index information. PPG is a non-invasive monitoring method for monitoring blood volume changes in living tissues by means of optoelectronics. When a light beam of a certain wavelength irradiates the skin surface on the back of the auricle, the light beam will be transmitted or reflected to the optoelectronic receiver. During this process, due to the absorption and attenuation of the light by the skin muscles and blood at the detection end, the light intensity detected by the detector will decrease. Among them, the absorption of light by the skin muscles, tissues, etc. remains constant throughout the blood circulation, while the blood volume in the skin changes pulsatively under the action of the heart. When the heart contracts, the peripheral blood volume is the largest, the light absorption is also the largest, and the detected light intensity is the smallest; while when the heart relaxes, it is just the opposite, and the detected light intensity is the largest. Therefore, the light intensity received by the optoelectronic receiver changes pulsatively. By converting this light intensity change signal into an electrical signal, the change in volumetric pulse blood flow can be obtained. It can be seen that the volumetric pulse blood flow contains many important physiological information of the cardiovascular system such as blood flow. At the same time, the volumetric pulse blood flow mainly exists in the microarteries, capillaries and other microvessels in the peripheral blood vessels. Therefore, the volumetric pulse blood flow also contains rich microcirculation physiological and pathological information, which is an important information source for us to study the human circulatory system.

[0042] The PPG signal contains many physiological and pathological information of the human circulatory system, respiratory system, etc. It has good application prospects in the non-invasive detection of parameters such as human blood pressure, blood flow, blood oxygen, cerebral oxygen, muscle oxygen, blood sugar, pulse rate, microcirculation, vascular resistance, respiratory rate, and respiratory volume.

[0043] The ECG sensor records the electrophysiological activities of the heart over time through the chest using electrocardiography (ECG) to monitor the heart rate, and the measured values can be transmitted to external electronic devices (such as mobile phones, tablets, etc.) via wireless connection. The external electronic devices then transmit them wirelessly to the cloud platform for processing, and the user's electrocardiogram information can be obtained through analysis.

[0044] In some embodiments, the open earphone 1 further includes a battery 40 and a control circuit board 50. The battery 40 and the sensor 30 are both electrically connected to the control circuit board 50, and the battery 40 is used to provide electrical energy for the control circuit board 50 and the sound - generating component 10.

[0045] When the open earphone 1 is a clip - on earphone 100, please refer to Figures 1 to 2 , the fixing component 20 includes a housing 21 and a connecting bridge 22. The connecting bridge 22 connects the housing 21 and the sound - generating component 10, and the housing 21 is opposite to the sound - generating component 10. The sensor 30 is arranged on the housing 21, the battery 40 is arranged inside the housing 21, and the control circuit board 50 is arranged inside the housing 21. Of course, the battery 40 and the control circuit board 50 can also be respectively arranged inside the housing 21 and inside the sound - generating component 10, or both the battery 40 and the control circuit board 50 are arranged inside the sound - generating component 10. In the wearing state, the housing 21 is located on the back of the user's auricle and cooperates with the sound - generating component 10 to clamp the user's...

[0046] When the clip - on earphone 100 is in the wearing state, the sensor 30 is arranged on the housing 21, and the housing 21 is located on the back of the user's auricle. Then the sensor 30 can be optionally arranged in the middle of the housing 21 to increase the contact area between the sensor 30 and the back of the user's auricle, better detect the attachment point behind the user's ear, and obtain more accurate health data.

[0047] When the open earphone 1 is a hook - type earphone 200, please refer to Figures 3 to 4 , the fixing component 20 includes a housing 21 and an ear hook 23. The ear hook 23 connects the housing 21 and the sound - generating component 10. The sensor 30 is arranged on the housing 21, the battery 40 is arranged inside the housing 21, and the control circuit board 50 is arranged inside the housing 21. Of course, the battery 40 and the control circuit board 50 can also be respectively arranged inside the housing 21 and inside the sound - generating component 10, or both the battery 40 and the control circuit board 50 are arranged inside the sound - generating component 10. The fixing component 20 is formed into an ear - hook structure for hanging between the back side of the user's ear and the head, and the sensor 30 is arranged on the ear hook 23. In the wearing state, the housing 21 is located on the back of the user's auricle, and the ear hook 23 is hung between the back side of the user's ear and the head.

[0048] When the ear-hook type earphone 200 is in a worn state, the sensor 30 is disposed on the housing 21, and the housing 21 is located on the back of the user's auricle. To facilitate the ear-hook 23 to be hung between the back side of the user's ear and the head, the external configuration of the housing 21 can be formed into an approximate cylindrical shape to form coherence in structure. At this time, the sensor 30 can be optionally disposed in the middle of the housing 21, which can increase the contact area between the sensor 30 and the back of the user's auricle and better perform alignment detection with the attachment point behind the user's ear; or the housing 21 can also be formed into other shapes such as a circular shape, and the sensor 30 can also be disposed in the middle of the housing 21, and the above effects can also be achieved.

[0049] In addition, an installation groove 211 is provided on the outer wall surface of the housing 21, and the sensor 30 is embedded in the installation groove 211, so that the sensor 30 can be stably installed on the housing 21; in another embodiment, the housing 21 is provided with a receiving cavity 212 and an installation hole 213. The installation hole 213 communicates the receiving cavity 212 with the outside. The battery 40 is disposed in the receiving cavity 212, and a part of the sensor 30 is located in the receiving cavity 212, and the other part blocks the installation hole 213, which can ensure the stable installation of the sensor 30 and prevent impurities such as dust and sewage from entering the inside of the housing 21. It can be understood that the form in which the sensor 30 is disposed on the housing 21 can also be in forms such as screwing and clamping, and the present application does not limit this.

[0050] Please refer to Figures 7 to 10 , the sound generating component 10 includes a first housing 11, a second housing 12 and a speaker assembly 13. The first housing 11 is connected to the fixing component 20. The second housing 12 has a sound outlet hole 121. The speaker assembly 13 is electrically connected to the battery 40 and the control circuit board 50. The speaker assembly 13 is installed on the first housing 11 or the second housing 12. The sound emitted by the speaker assembly 13 is transmitted into the user's ear canal through the sound outlet hole 121.

[0051] The materials of the first housing 11 and the second housing 12 can be plastic, silicone, etc., and the shapes of the first housing 11 and the second housing 12 can be the same or different, and their volumes can also be the same or different. For example, the first housing 11 can be an approximate cylindrical structure or an approximate spherical structure. And the second housing 12 can be an approximate cylindrical structure or an approximate rectangular structure, and the present application does not limit this.

[0052] Among them, the second housing 12 is movably connected to the first housing 11, so that the second housing 12 can be telescopic relative to the first housing 11, so that the distance between the sound outlet hole 121 and the user's ear canal opening can be adjusted when the open earphone 1 is worn. Therefore, when the user feels that the volume of the speaker assembly 13 is too small, the distance between the sound outlet hole 121 and the ear canal opening can be shortened by telescoping the second housing 12 to increase the sound. When the user feels discomfort caused by the unreasonable position of the second housing 12 in the ear canal opening area, the distance between the second housing 12 and the ear canal opening is increased by telescoping the second housing 12. With such a setting, the open earphone 1 of the present application can not only perform health detection on the user, but also be applicable to users with different ear sizes, further increasing the practical range of the open earphone 1.

[0053] There are various ways of movably connecting the second housing 12 to the first housing 11. In some embodiments of the present application, the second housing 12 is sleeved on the first housing 11, and the second housing 12 is slidable relative to the first housing 11. It can be understood that the second housing 12 can be sleeved outside the first housing 11, or the first housing 11 can be sleeved outside the second housing 12. Among them, the sleeved form enables the second housing 12 and the first housing 11 to conveniently adjust the position of the second housing 12 relative to the first housing 11. In some other embodiments, the second housing 12 and the first housing 11 can also be in the form of threaded connection, snap connection, etc. Here, the present application does not limit the specific connection method between the second housing 12 and the first housing 11.

[0054] In the solution where the second housing 12 is sleeved outside the first housing 11, the first housing 11 is provided with an installation cavity, and the installation cavity has an opening 111 on the side away from the fixing member 20. Among them, the speaker assembly 13 can be arranged in the installation cavity or in the second housing 12; the second housing 12 is slidably sleeved outside the first housing 11, and the sound outlet hole 121 communicates with the installation cavity through the opening 111. With such a setting, the user can adjust the position of the second housing 12 relative to the first housing 11 by sliding the second housing 12 according to his own needs, so as to adapt to the ear sizes and ear canal positions of different users, so as to obtain better wearing comfort and sound quality performance.

[0055] The second housing 12 is sleeved outside the first housing 11, making the product appearance more beautiful and compact. Moreover, the first housing 11 can be better integrated with the second housing 12, thus reducing protruding components and enhancing the overall aesthetic feeling. In addition, while the second housing 12 can protect the first housing 11, users can also easily remove the second housing 12 for cleaning. It can be understood that the form in which an open end 111 is formed at one end of the first housing 11 away from the fixing component 20 can make the assembly and maintenance of the speaker assembly 13 more convenient. In other structural forms, a wall body for covering the open end 111 can also be provided at one end of the first housing 11 away from the fixing component 20, and a sound emitting port is provided on the wall body.

[0056] To prevent the second housing 12 from rotating around the first housing 11, the shape of the connecting part between the first housing 11 and the second housing 12 is adapted to the inner hole shape of the second housing 12, and the first housing 11 and the second housing 12 are relatively fixed in the circumferential direction of the second housing 12. That is, the orthographic projection of the first housing 11 in the sliding direction of the second housing 12 is non-circular, such as an ellipse, a square circle, etc. The inner contour shape of the second housing 12 is adapted to the outer contour shape of the second housing. With such a setting, the first housing 11 can prevent the second housing 12 from rotating during sliding. In this way, even if the user makes head movements or activities, the second housing 12 will not accidentally rotate or shift around the first housing 11, ensuring the stability of the position of the second housing 12 and the headphone sound quality. Of course, in some other embodiments, a limiting surface can also be provided on the outer surface of the first housing 11, wherein at least part of the limiting surface is a plane. In this way, the second housing 12 can also be prevented from rotating around the first housing 11.

[0057] In the solution where the second housing 12 is sleeved inside the first housing 11, the second housing 12 is slidably nested inside the first housing 11 and can at least partially extend out of the first housing 11 from the open end 111. Among them, the speaker assembly 13 can be arranged in the installation cavity or in the second housing 12. With such a setting, the first housing 11 can play a role in protecting the second housing 12 and extending the service life of the second housing 12.

[0058] To improve the relative fixation between the second housing 12 and the first housing 11 during the sliding process, the sound generating component 10 in the embodiment of the present application further includes a damping member 14. The damping member 14 relatively fixes the first housing 11 and the second housing 12 after telescopic movement. The specific form of the damping member 14 can be block-shaped or ring-shaped. Here, the present application does not limit the specific installation form of the damping member 14. In addition, the material of the damping member 14 can include but is not limited to rubber, silica gel, polyurethane, etc.

[0059] In some embodiments, such as Figure 9 andFigure 10 As shown, the damping member 14 is located between the first housing 11 and the second housing 12. The damping member 14 can be a damping ring or a damping sheet clamped between the first housing 11 and the second housing 12. Alternatively, the damping member 14 is a damping ring or a damping sheet, and the damping member 14 is fixed to one of the first housing 11 and the second housing 12 and elastically abuts against the other of the first housing 11 and the second housing 12.

[0060] It can be understood that the damping ring and the damping sheet can be selectively provided or provided simultaneously. The damping ring and the damping sheet can provide a damping effect between the second housing 12 and the first housing 11, so that the second housing 12 can be relatively fixed at different positions of the first housing 11. Of course, in some other embodiments, the damping member 14 can also be a card slot provided at intervals on the outer wall of one of the second housing 12 or the first housing 11 and a buckle provided on the inner wall of the other of the first housing 11 or the second housing 12. By engaging the buckle with different card slots, the second housing 12 can be relatively fixed at different positions of the first housing 11.

[0061] In some embodiments, the sound generating component 10 further includes a metal mesh (not shown in the figure). The metal mesh is installed on the second housing 12 and covers the sound outlet hole 121. The metal mesh is mainly used to prevent external impurities from entering the earphone interior through the sound outlet hole 121, protect the internal sound generating unit and other components, and extend the service life of the device.

[0062] In some embodiments, please refer to again Figures 1 to 3 , in order to further achieve that the open earphone 1 has a relatively comfortable clamping force on the ear, the open earphone 1 further includes a shape memory wire 60. The shape memory wire 60 can be installed on the fixing component 20, specifically on the connection bridge 22 and the earhook 23. In this way, while ensuring the structural stability, it can also improve the user's wearing experience, and can ensure the fitting degree between the sensor 30 and the back of the user's auricle in the wearing state, thereby ensuring the accuracy of the sensor 30 for collecting the user's biological information.

[0063] It should be noted that the shape memory wire 60 is made of an alloy with memory performance, usually composed of materials such as nickel, titanium, platinum, copper, silver, etc. The shape memory wire 60 has high elasticity, wear resistance and stability, and it can maintain its original shape and performance in different temperature and humidity environments. Thus, during the wearing process, it can ensure that there is an appropriate pressure between both the housing 21 and the sound generating component 10 and the ear, making the open earphone 1 more firmly fixed around the ear and not easily loose or swing. Moreover, the shape memory wire 60 has high elasticity and durability, can better adapt to the ear sizes of different users to meet the usage requirements of different users, and can withstand long-term stretching and compression without being easily deformed or fatigued, extending the service life of the open earphone 1.

[0064] In some embodiments, the open earphone 1 further includes a conductive wire 70, and the conductive wire 70 is electrically connected to the battery 40, the control circuit board 50, and the speaker assembly 13. The conductive wire 70 is disposed through the connection bridge 22 and the earhook 23 and is bent, which is beneficial to the compactness of the overall structure and the aesthetic appearance. Of course, in some other embodiments, a wire groove may also be provided on the outer wall surfaces of the connection bridge 22 and the earhook 23, and the conductive wire 70 is respectively connected to the battery 40, the control circuit board 50, and the speaker assembly 13 through the wire groove. The present application is not limited thereto.

[0065] Further, the above-mentioned shape memory wire 60 is arranged in parallel with the conductive wire 70. It should be noted that the parallel arrangement means that the shape memory wire 60 and the conductive wire 70 extend in the same direction and have a gap between them. By setting it in this way, the distance between the shape memory wire 60 and the conductive wire 70 can be maintained, avoiding cross-winding between them, and making the spatial layout of the open earphone 1 more reasonable. In addition, while the shape memory wire 60 makes the connection bridge 22 and the earhook 23 elastic, it can also provide a certain supporting effect on the connection bridge 22 and the earhook 23. When the open earphone 1 is subjected to external force punching, the shape memory wire 60 can play a certain role in protecting the conductive wire 70, avoiding risks such as pulling and bending of the conductive wire 70.
