Technical Field

[0001] This application relates to a bone conduction headphone that incorporates optical devices and can simultaneously perform multiple physiological monitoring functions. Background Technology

[0002] Headphones are a common wearable device in modern times. They reduce external interference and prevent disturbing others, and connect to communication devices wirelessly for communication and online conferencing. In recent years, many runners and swimmers have adopted the habit of wearing headphones during training, not only for music enjoyment but also to receive simultaneous training information. Currently, there are four types of headphones: in-ear, on-ear, over-ear, and bone conduction. Bone conduction headphones have gained popularity among athletes in recent years because they can simultaneously receive ambient sound, reducing the risk of accidents caused by unawareness of surroundings. However, both athletes and the general public have a need for physiological monitoring, and wearing devices for this purpose represent the future trend. Summary of the Invention

The overall structure includes an earphone body 2 and an ear hook device 3. The earphone body 2 and the ear hook device 3 can be integrated or connected by assembly, which is not limited here. The ear hook device 3 is hung on the back of the ear and must be in contact with the skin when worn.

[0031] Please see Figure 2 , Figure 2 yes Figure 1A rear view of the earphone 1 according to an embodiment of this application shows that this side is attached to the ear shell and surrounding tissue. The earphone body 2 has a shell 21, on which a vibration module 41, a first optoelectronic transceiver module 42, and a temperature sensing module 43 are provided. The shell 21 at the position of the temperature sensing module 43 is a conical structure 28. This conical structure 28 is inserted into the external ear canal when worn, allowing the front end of the temperature sensing module 43 to enter the external ear canal. In addition, a second optoelectronic transceiver module 32 is disposed on the ear hook device 3, which is the attachment side 31. The second optoelectronic transceiver module 32 is not limited to any position on the ear hook device.

[0032] Please see Figure 3 and Figure 4 , Figure 3 This is an exploded view of the headphone structure according to an embodiment of this application, showing the components and modules unfolded along the longitudinal axis of the housing. Figure 4 This is a cross-sectional view of the earphone body according to an embodiment of this application. The housing 21 contains two PCB boards, namely a control board 22 and a connection board 23. The two boards are electrically connected to each other for bidirectional signal transmission and power supply. The electrical connection can be a connecting wire, a flexible printed circuit board (FPCB), or a board-to-board connector, and is not limited thereto. In this embodiment, a controller 24 is disposed on the control board 22, which is the center of signal control and power control, and can be connected to an external device through a communication module 25. The external device determines the system operation. The external device can be a mobile phone, tablet computer, or any other device that can communicate bidirectionally with the communication module 25 of the earphone of this invention via wireless communication. The controller in this embodiment can be a microcontroller (MCU) or a system-on-a-chip (SoC), and is not limited thereto.

[0033] Please see Figure 5 , Figure 5 This is a side view of a connecting plate according to an embodiment of this application. The first side 27 of the connecting plate 23 is equipped with a vibration module 41, a first photoelectric transceiver module 42, and an infrared temperature sensing module 43. The vibration module 41 and the first photoelectric transceiver module 42 are on the same plane as the surface of the housing 21 and are attached to the skin surface when worn. The vibration module 41 is attached to the area in front of the ear and near the cheekbone, and provides sound through vibration. The sound is transmitted to the inner ear via bone conduction through the cheekbone (bone labyrinth). The vibration frequency of the vibration module 41 can be controlled by the controller 24 according to an external device.

[0034] Please refer to the following: Figure 5In one embodiment of this application, the vibration module 41 is placed on the first side 27 of the connecting plate 23. The vibration module 41 can be composed of a micro-electro-mechanical system (MEMS) speaker or other vibration components that can provide audio frequency bands. The vibration module of this embodiment of the invention preferentially uses a MEMS speaker due to size factors. MEMS components are small in size and convenient for users to wear.

[0035] Please see Figure 6 , Figure 6 This is a structural diagram of a first optoelectronic transceiver module according to an embodiment of this application. The first optoelectronic transceiver module 42 includes a light-emitting component and a sensing component. The light-emitting component includes at least a first light-emitting component 421 and a second light-emitting component 422. The sensing component is a first sensing component 423. The light-emitting components can be added according to algorithm requirements. The first light-emitting component 421 emits a light beam of a first wavelength, and the second light-emitting component 422 emits a light beam of a second wavelength. Both light beams are directed towards the skin of the contact surface of the first optoelectronic transceiver module 42. Photons in the light beams enter the skin, and some photons leave the skin surface through diffuse reflection and are received by the first sensing component 423 to measure the diffuse reflection result. The first light-emitting component 421 and the second light-emitting component 422 can emit light beams individually or alternately. In the alternating emission state, the emission time of the light beams must be asynchronous.

[0036] The first light-emitting component 421 in the first optoelectronic transceiver module 42 emits a first wavelength, which is visible light, with a wavelength range of 400-700 nanometers. The second light-emitting component 422 emits a second wavelength, which is near-infrared light (NIR), with a wavelength range of 700-1000 nanometers. In one embodiment of this application, the first transceiver module has two light-emitting components, and the number is not limited, but the center wavelength of any additional light-emitting component must be at least 30 nanometers away from both the first and second wavelengths. In another embodiment, a light-emitting block is established in the first optoelectronic transceiver module 42, and a filter is provided in the light-emitting block. This light-emitting block can be composed of a matrix of small blocks, each small block consisting of narrow-wave filters of different wavelengths. In this case, the light-emitting components and filters are not limited to 30 nanometers.

[0037] Please refer to the following: Figure 6The first sensing component 423 in the first optoelectronic transceiver module 42 receives photons emitted by the first light-emitting component 421 and the second light-emitting component 422 after diffuse reflection by the skin. The sensitive wavelength range of the first sensing component 423 is at least 500 to 850 nanometers, covering at least the first and second wavelengths. In another embodiment, if the first optoelectronic transceiver module 42 has other light-emitting components besides the first and second light-emitting components 421 and 422, then the wavelength range of the first sensing component 423 must cover all emitted wavelengths on the first optoelectronic transceiver module 42.

[0038] Please refer to the following: Figure 6 In the first optoelectronic transceiver module 42, the first light-emitting component 421 and the second light-emitting component 422 can be separately packaged LEDs or LEDs packaged on the same chip; there is no limitation on this. The first sensing component 423 consists of a single photodiode. Alternatively, the first light-emitting component 421, the second light-emitting component 422, and the first sensing component 423 can be packaged into a single module; there is no limitation on the form of construction.

[0039] Please refer to the following: Figure 3 The first optoelectronic transceiver module 42 and the controller 24 transmit signals bidirectionally. The controller 24 transmits operating signals to the first optoelectronic transceiver module 42, and the first optoelectronic transceiver module 42 sends data signals to the controller 24. This data signal is the photon count information detected by the first sensing component 423, which comes directly from the diffuse reflection signal of the skin. The controller 24 or an external device calculates the first physiological information, including blood oxygen concentration (SpO2) and heart rate.

[0040] Please refer to the following: Figure 5 In some embodiments of this application, the first side 27 also has a temperature sensing module 43, which includes a transmitting component and a receiving component (not shown here). The wavelength of the light beam emitted by the transmitting component is near-infrared light, and the receiving component may be a thermopile sensor (not limited thereto). After the emitted light beam enters the inner ear, it reflects infrared light through the principle of near-blackbody radiation and irradiates the thermopile to generate an electromotive force (voltage difference). The body temperature inside the ear is obtained by using the Seebeck coefficient of the thermopile material.

[0041] Please see Figure 7 , Figure 7In one embodiment of this application, a shielding member 44 is used to reduce signal interference between the vibration module 41, the first optoelectronic transceiver module 42, and the temperature sensing module 43 on the first side 27. Since the vibration module 41 generates high-frequency vibration waves when producing audio, and the MEMS speaker generates some electromagnetic waves during operation, a shielding member 44 is provided on the first side 27 in this embodiment. In addition to the outer shielding wall 441, the shielding member 44 has at least one shielding partition 442 between the modules, and a circular shielding ring structure around the vibration module. The shielding member 44 is made of metal. The height of the shielding member is only the height difference between the surface of the first side 27 and the surfaces of the vibration module 41, the first optoelectronic transceiver module 42, and the housing 21; the gaps between the shielding member and the modules and the first side 27 are filled with cured adhesive.

[0042] Please see Figure 8 , Figure 8 This is a structural diagram of a second optoelectronic transceiver module according to one embodiment of this application. The second optoelectronic transceiver module 32 includes a light-emitting component and a sensing component, and the light-emitting component includes at least a third light-emitting component 321. In another embodiment, light-emitting components with different emission wavelengths can be added, and the emission wavelengths of each light-emitting component are at least 50 nanometers apart. The sensing component in the second optoelectronic transceiver module 32 is a second sensing component 322. The center wavelengths of the light-emitting components of the second optoelectronic transceiver module must all be in the short-wave infrared range. In this embodiment, the center wavelengths of the light-emitting components used are between 1,000 and 1,600 nanometers. Furthermore, the second sensing component 322 consists of a single photodiode, and the range of light wavelengths it receives must cover the emission wavelengths of all the light-emitting components in the second optoelectronic transceiver module 32.

[0043] Please refer to the following: Figure 8 In one embodiment of this application, the third light-emitting component 321 emits a third wavelength for the purpose of detecting whether it is in a wearing state. After the third light-emitting component 321 emits a light beam, the diffuse reflection light is detected by the second sensing component 322. The type of the irradiated object is determined by the reflectivity. If the reflectivity is 0, it may be air or a black body, which is not a wearing state. If the reflectivity is >70%, it is a highly reflective material, which is also not a wearing state. The reflectivity in the wearing state depends on the wavelength. Different skin colors will cause slight differences in reflection, but this difference is much smaller in short-wave infrared light than in visible light. In the ear wearing state, the light intensity detected by the second sensing component 322 should be 20 to 50% of that of the third light-emitting component 321.

[0044] In one embodiment of this application, the second optoelectronic transceiver module 32 can be configured with two light-emitting components to improve the accuracy of determining the wearing status. Both light-emitting components emit wavelengths in the short-wave infrared band. The emission wavelengths of the two light-emitting components can both be specific absorption wavelengths of the skin, or one can be a specific absorption wavelength while the other is not. The two emission wavelengths can emit light beams individually or alternately. In the alternating emission state, the emission time of the light beams must be asynchronous.

[0045] Please refer to the following: Figure 3 In some embodiments of this application, the second optoelectronic transceiver module 32 and the third light-emitting component 321 emit third wavelengths of selectable wavelengths, including 1,200 nm, 1,450 nm, and 1,550 nm. Water molecules have a certain degree of absorption rate for different wavelengths in the short-wave infrared band, but they have a more obvious characteristic absorption wavelength at 1,450 nm. A wavelength of 1,200 nm is the characteristic absorption wavelength of lipids and can be used to detect lipids in the skin; a wavelength of 1,550 nm is the characteristic absorption wavelength of glucose and can be used to detect glucose molecules in the skin. These wavelengths can all be used to detect water molecules in the skin, and thus detect the wearing status. The detection of the wearing status is not limited to detecting water molecules in the skin, therefore no limitation is set.

[0046] Please also refer to Figure 3 and Figure 6 In one embodiment of this application, the control board 22 is provided with a communication module 25. This communication module 25 is used to receive signals from external devices and transmit them to the controller 24, and also to transmit data signals from the controller 24 to external devices. The communication module 25 in this embodiment can be a short-range communication module such as a Bluetooth module or a WiFi module, and is not limited thereto. In other embodiments, the communication module 25 can be located in other structural positions within the housing.

[0047] Please refer to the following: Figure 3 In one embodiment of this application, the control board 22 is provided with a power module 26, which provides the power required for the operation of the controller 24, communication module 25, vibration module 41, first optoelectronic transceiver module 42, temperature sensing module 43, and second optoelectronic transceiver module 32 of the earphone 1. In this embodiment, the power module 26 can be a rechargeable battery such as a lithium-ion battery or a lithium polymer battery, or it can generate electricity through the temperature difference between the skin and air using a series thermoelectric material (such as Bi2Te3) to extend the earphone's battery life; this is not a limitation. In other embodiments, the communication module 25 can be located in other structural positions within the housing.

[0048] Please refer to the following: Figure 3In one embodiment of this application, the housing 21 is composed of an inner housing 21a and an outer housing 21b. The inner housing 21a is the side that is close to the skin and has a conical structure 27 of the housing 21. The inner housing 21a and the outer housing 21b can be connected by a snap fastener.

[0049] In summary, the earphone 1 of this application combines a vibration module with a temperature sensing module, a first photoelectric transceiver module, and a second photoelectric transceiver module to simultaneously perform multiple physiological monitoring functions. Specifically, the vibration module 41 provides audio to the user through a MEMS speaker. While providing audio, the earphone 1 measures first physiological information via the diffuse reflection generated after the first photoelectric transceiver module 42, which uses a beam of light with visible and near-infrared wavelengths, irradiates the skin. The temperature sensing module 43, constructed using a thermopile sensor, accurately measures body temperature by inserting a conical structure 28 on the housing 21 into the external auditory canal. A second photoelectric transceiver module 32, located on the attachment side 31 of the ear hook device 3, uses a short-wave infrared LED as a light source, along with a corresponding photodiode, to measure second physiological information via diffuse reflection generated after irradiation of the skin.

[0050] Please refer to the following: Figure 3 In another embodiment of this application, the conical structure 28 on the housing 21 may be assembled with the housing 21, rather than being integrally formed. In the assembled state, its thickness may have its own component thickness.

[0051] Please also refer to Figure 6 and Figure 8 In another embodiment of this application, the first sensing component 423 of the first optoelectronic transceiver module 42 may use a full-spectrum silicon-based photodiode with a sensing range of 190 to 1,100 nanometers. Its sensing range can also be reduced by coating the encapsulation surface, but it must at least encompass the emission wavelengths of all light-emitting components of the first optoelectronic transceiver module 42. The center wavelengths of the light-emitting components of the second optoelectronic transceiver module 32 must all be in the short-wave infrared range, which is 1,000 to 2,500 nanometers. The second sensing component 322 uses a photodiode made of indium gallium arsenide (InGaAs) material, with a maximum sensing range encompassing the short-wave infrared range. Commonly used InGaAs photodiodes have a sensing range of 900 to 1,700 nanometers, covering the emission wavelengths of all light-emitting components on the second optoelectronic transceiver module 32. Because the first sensing component 423 and the second sensing component 322 are not adjacent in their configuration, their sensing wavelength ranges may overlap.

[0052] Please see Figure 9 , Figure 9This is a diagram showing the setup of the first optoelectronic transceiver module according to another embodiment of this application. Both the first optoelectronic transceiver module 42 and the second optoelectronic transceiver module 32 rely on diffuse reflection caused by a light beam irradiating the skin. The first sensing component 423 and the second sensing component 322 sense the photons after diffuse reflection. In this embodiment, both the first optoelectronic transceiver module 42 and the second optoelectronic transceiver module 32 are disposed on the ear-mount device 3, and the first optoelectronic transceiver module 42 and the second optoelectronic transceiver module 32 are mounted on the same FPCB (not shown) and connected to the connecting board 23.

[0053] refer to Figure 10 , Figure 10 This is a side view of the connecting plate 23 according to another embodiment of this application. The vibration module 41 is disposed on one outer side of the connecting plate 23 and is not fixed to the connecting plate 23. It can be connected to the control plate 22 by wires through the inner side of the shielding ring 443 attached to the shielding member 44. If the selected vibration module 41 is a large module, it can also be disposed on the control plate 22 (not shown).

[0054] Please refer to Figure 11 , Figure 11 This is a flowchart illustrating the operation of one embodiment of this application. When the user removes the earphone 1 from the charging device (not shown) (step S1), the connection with the external power source is terminated. The charging device can be an earphone case or other means that can charge the earphone 1. After the earphone 1 loses its external power source, the power module 26 of the earphone 1 immediately provides power to the controller 24 on the control board 22. The controller 24 determines to provide power to the second optoelectronic transceiver module 32 on the ear hook device 3, and specifies that the third light-emitting component 321 of the second optoelectronic transceiver module 32 emits a beam of light of the third wavelength (step S2). The beam of light of the third wavelength is emitted towards the skin. After the beam is diffusely reflected by the skin, the photons leave the skin. The diffusely reflected photons are sensed by the second sensing component 322 of the second optoelectronic transceiver module 32. Since the third light-emitting component 321 has a specific power for emitting the beam of the third wavelength, the number of photons sensed by the second sensing component 322 is used by the controller 24 to determine the ratio of the number of photons to the number of photons in the emitted wavelength beam, and to determine whether the earphone is in a wearing state (step S3).

[0055] After determining the wearing status, if it is not in a wearing status, the third wavelength beam is continuously emitted in a periodic manner, repeating step S3; if it is in a wearing status, the controller 24 connects with the external device through the communication module 25 to determine if there is an instruction from the external device (step S4). The earphone 1 has four modules: vibration module 41, first optoelectronic transceiver module 42, temperature sensing module 43, and second optoelectronic transceiver module 32. The external device can specify the functions provided by the four modules, and the controller 24 will provide power and signals to the modules whose functions are specified by the external device (step S5). After the first optoelectronic transceiver module 42, temperature sensing module 43, and second optoelectronic transceiver module 32 execute, they will provide the measured data to the controller 24 and transmit it to the external device through the communication module 25. If there is no instruction from an external device, the controller 24 will periodically instruct the three modules, namely the first optoelectronic transceiver module 42, the temperature sensing module 43 and the second optoelectronic transceiver module 32, to perform their functions. After execution, the modules will provide the measured data to the controller 24 and accumulate and store the data in the storage device (not shown) on the connection board. When the controller 24 communicates with the external device, it will actively provide the data to the external device and erase the data in the storage device after providing the data to the external device.

[0056] After performing its function, the vibration module 41 on the earphone body 2 provides audio to the user (step S61). The vibration module 41 only operates when actively given instructions by an external device and has no data feedback function. After performing its function, the first optoelectronic transceiver module 42 on the earphone body 2 provides real-time first physiological information (step S62). After performing its function, the temperature sensing module 42 on the earphone body 2 provides real-time body temperature (step S63). After performing its function, the second optoelectronic transceiver module 32 on the ear hook device 3 provides real-time second physiological information (step S64). The first physiological information includes at least values ​​such as heart rate and blood oxygen, and the second physiological information includes at least one of the values ​​of blood glucose concentration, blood lipid concentration, and uric acid concentration.

[0057] Please see Figure 12 , Figure 12This is a schematic diagram illustrating the emission wavelength time period of the first and second light-emitting components according to an embodiment of this application. In the physiological monitoring method of this embodiment, the first photoelectric transceiver module 42 and the second photoelectric transceiver module 32, upon receiving an instruction from an external device, enter an execution period 5. If no instruction is received from an external device, they will continuously and intermittently detect; the intermittent detection will be described later in this paragraph. In this embodiment, when the first photoelectric transceiver module is executed, the first light-emitting component 421 emits a light beam of a first wavelength in a first cycle, and the second light-emitting component 422 also emits a light beam of a second wavelength in a first cycle. There must be a time difference between the emission of the light beams by these two light-emitting components. This time difference must meet the recognition capability of the first sensing component 423. If the first photoelectric transceiver module has other added light-emitting components, they only activate upon receiving an instruction from an external device, and at least two light-emitting components are used in each execution. The execution time of each execution is the first execution period 51, in which the first light-emitting component 421 emits a light beam of the first wavelength and the second light-emitting component 422 emits a light beam of the second wavelength several times in the first cycle. The length of the first execution period 51 depends on the emission power of the first light-emitting component 421 and the second light-emitting component 422 and the requirements of the algorithm. The result of the algorithm provides the first physiological information.

[0058] Please refer to the following: Figure 12 When the controller 24 of the earphone 1 does not receive instructions from an external device, the first optoelectronic transceiver module 42 will continuously emit a first wavelength beam and a second wavelength beam using the first light-emitting component 421 and the second light-emitting component 422. The time point for emitting the beam is one first execution period 51 in the third cycle. In each first execution period 51, the first light-emitting component 421 and the second light-emitting component 422 emit the first wavelength beam and the second wavelength beam within a number of first cycles.

[0059] Please see Figure 13 , Figure 13This is a schematic diagram of the emission wavelength time period of the second optoelectronic transceiver module according to an embodiment of this application. If the controller 24 of the earphone 1 does not receive a command from an external device, the third light-emitting component 321 in the second optoelectronic transceiver module 32 emits a beam of light of the third wavelength in a second cycle. If the second optoelectronic transceiver module 32 has additional light-emitting components, such as a first additional light-emitting component and a second additional light-emitting component, the third light-emitting component 321 emits a beam of light of the third wavelength in a second cycle, the first additional light-emitting component also emits a beam of light of the first additional wavelength in a second cycle, and the second additional light-emitting component also emits a beam of light in a second cycle. There is a certain time difference between the emission of the three components. This time difference must meet the recognition capability of the second sensing component 322. Each execution is performed several times in a second execution period 52, which is performed in a fourth cycle. The length of the second execution period 51 depends on the emission power of the third light-emitting component 421, the first additional light-emitting component, and the second additional light-emitting component, and the algorithm requirements. The result of the algorithm provides second physiological information.

[0060] Please refer to the following: Figure 2 In one embodiment of this application, the first photoelectric transceiver module 42 provides first physiological information such as heart rate and blood oxygen, which changes rapidly. Whether it is real-time monitoring with external device instructions or anytime monitoring without external device instructions, it must transmit at a high frequency to provide the first physiological information. The second photoelectric transceiver module 32 is used to determine the wearing status and provides second physiological information such as blood glucose concentration, blood lipid concentration or uric acid concentration. The required monitoring does not need to be too high-frequency. In this example, the fourth cycle is greater than the third cycle.

[0061] Please refer to the following: Figure 2 In one embodiment of this application, the vibration module 41, the first optoelectronic transceiver module 42, the temperature sensing module 43, and the second optoelectronic transceiver module of the earphone 1 can perform specific functions upon receiving instructions from an external device, or all modules can perform these functions simultaneously. Furthermore, after the earphone 1 is removed from its charging device, and the second optoelectronic transceiver module 32 detects and the controller 24 determines that it is in a wearing state, at least the second optoelectronic transceiver module 32 and the first optoelectronic transceiver module 42 continuously perform physiological monitoring, providing first and second physiological information.

[0062] In summary, one embodiment of this application provides an earphone that provides audio information via bone conduction. This earphone also has the ability to simultaneously monitor heart rate, blood oxygen, and body temperature, and even monitor continuous blood glucose concentration, blood lipid concentration, and uric acid concentration using shortwave infrared light.
