[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0030] The purpose of this invention is to provide a smart Bluetooth headset suitable for health monitoring, which can monitor the wearer's exercise status and vital signs in real time during exercise, and issue a reminder signal to stop exercising when the wearer is no longer suitable to continue exercising, so as to avoid accidents during exercise.
[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0032] Example 1:
[0033] This embodiment provides a smart Bluetooth headset suitable for health monitoring, such as... Figure 1 As shown, the smart Bluetooth headset includes a headset body, an extension part, a processor 1, an accelerometer 2, an infrared temperature sensor 3, and a photoelectric sensor 4.
[0034] The earphone itself has a sound-generating device that transmits sound emitted by the earphone to the listener's ear. This earphone body and sound-generating device are standard features of existing Bluetooth earphones and will not be described in detail here.
[0035] The extension extends from the headphone body into the ear.
[0036] Accelerometer 2, installed on the earphone body, is used to collect acceleration information during the wearer's movement.
[0037] Infrared temperature sensor 3, installed on the extension, is used to collect the body temperature information of the headphone wearer during exercise.
[0038] Photoelectric sensor 4, mounted on the extension, is used to collect physiological information of the headphone wearer during exercise, including heart rate, blood pressure, and blood oxygen.
[0039] The processor 1 is connected to the accelerometer 2, the infrared temperature sensor 3, and the photoelectric sensor 4. It is used to determine the state of the headphone wearer based on acceleration information, body temperature information, and physiological information. When the headphone wearer's state is unsuitable for continued exercise, it controls the headphone body to issue a reminder signal to stop exercising.
[0040] In this embodiment, the infrared temperature sensor 3 can be a pyroelectric infrared sensor. Pyroelectric infrared sensors utilize the thermal effect of infrared radiation to cause temperature changes in the element itself, thereby detecting certain parameters. Alternatively, the infrared temperature sensor 3 can be an infrared thermopile temperature sensor. Infrared thermopile temperature sensors utilize the thermal effect of infrared radiation to measure the absorbed infrared radiation, indirectly measuring the temperature of the object radiating infrared light. Both of these sensors can acquire the ear canal temperature of the earphone wearer in real time. This is a non-contact temperature measurement method with advantages such as high accuracy, small size, fast response speed, and low power consumption. It should be noted that the above two sensors are merely examples, and the present invention is not limited to these two sensors.
[0041] Preferably, the smart Bluetooth headset in this embodiment further includes a signal amplifier 5, which is located between the infrared temperature sensor 3 and the processor 1. The signal amplifier 5 amplifies the body temperature information and transmits the amplified body temperature information to the processor 1. At this time, the output terminal of the infrared temperature sensor 3 is connected to the input terminal of the signal amplifier 5, and the output terminal of the signal amplifier 5 is connected to the infrared signal input terminal of the processor 1. During the movement of the headset wearer, the infrared temperature sensor 3 is used to collect the headset wearer's ear temperature (i.e., body temperature information) in real time and convert the body temperature information into an electrical signal. The signal amplifier 5 is used to amplify the electrical signal to obtain an amplified signal. The processor 1 is used to convert the amplified signal into body temperature data, so as to complete the function of collecting the headset wearer's body temperature using the Bluetooth headset. The headset wearer's body temperature can be monitored at any time to understand the headset wearer's health status.
[0042] Furthermore, the infrared temperature sensor 3 in this embodiment may also have a compensation voltage input terminal, which is connected to the compensation voltage output terminal of the processor 1. The processor 1 is used to output a compensation voltage to the infrared temperature sensor 3 through the compensation voltage output terminal and the compensation voltage input terminal. The infrared temperature sensor 3 is used to receive the compensation voltage output by the processor 1 to compensate for errors in the collected body temperature information, thereby collecting more accurate body temperature information.
[0043] The compensation voltage is determined based on the predetermined error value of the infrared temperature sensor 3. The error value is determined by acquiring the environmental measurement value of the infrared temperature sensor 3 in a preset temperature environment, calculating the absolute value of the difference between the environmental measurement value and the preset temperature, and obtaining the error value.
[0044] The light emitted by the photoelectric sensor 4 in this embodiment can illuminate the inner wall of the ear canal, and the photoelectric sensor 4 can receive the light reflected back from the inner wall of the ear canal. At this time, the photoelectric sensor 4 can determine the physiological information of the headphone wearer by detecting the change in the intensity of the received reflected light. The physiological information may include heart rate, blood pressure and blood oxygen.
[0045] Specifically, the photoelectric sensor 4 can include a light emitter and a photosensitive sensor. The light emitter emits detection light towards the inner wall of the ear canal, and the photosensitive sensor receives the reflected light from the inner wall of the ear canal. The reason physiological information can be determined based on changes in the intensity of the reflected light is that when the detection light emitted from the light emitter is reflected back to the photosensitive sensor after passing through the ear skin tissue, the absorption of the detection light by the skin tissue causes the reflected light received by the photosensitive sensor to be attenuated to a certain extent compared to the detection light emitted by the light emitter. Since the ear bones, skin, and other connecting tissues are static, the amount of detection light they absorb usually remains constant. Conversely, because the blood flow in arteries and capillaries varies at different times, their absorption of detection light also varies. After receiving the reflected light, the photosensitive sensor can convert the intensity of the reflected light into an electrical signal. Based on the received electrical signal, a basically constant DC signal and a changing AC signal can be extracted. Heart rate information can be calculated based on the changing AC signal. Similarly, the blood volume in the blood vessels of the ear changes pulsatilely under the contraction and relaxation of the heart. When the heart contracts, the blood volume in the blood vessels is at its maximum, and the absorption of detection light by the ear is also at its maximum, resulting in the minimum intensity of the detected reflected light. Conversely, when the heart relaxes, the blood volume in the blood vessels is at its minimum, and the absorption of detection light by the ear is also at its minimum, resulting in the maximum intensity of the detected reflected light. This pulsatile change in the intensity of the reflected light detected by the photoelectric sensor 4 allows for the determination of changes in blood flow within the blood vessels, which in turn helps in determining blood pressure. Furthermore, the degree of absorption of detection light by the blood vessels varies depending on the oxygen content within the blood vessels, allowing for the acquisition of blood oxygen levels based on changes in the intensity of the detected reflected light.
[0046] In this embodiment, by setting up an extension and a photoelectric sensor 4, physiological information such as heart rate, blood pressure and blood oxygen of the headphone wearer can be collected. The subsequent processor 1 can further generate physiological data based on this physiological information, thereby enabling real-time monitoring of the physiological data of the headphone wearer during exercise.
[0047] Preferably, the extension in this embodiment is suitable for insertion into the external auditory canal. At this time, the photoelectric sensor 4 can collect physiological information through the signal changes in the external auditory canal. Since the external auditory canal is located in a relatively deep position of the external ear, the external ambient light rarely enters the external auditory canal. Therefore, the influence of the external ambient light on the measurement results of physiological information is small and can be ignored, making the detected physiological information highly reliable.
[0048] Since the smart Bluetooth headset of this embodiment is used during exercise, the movement of the body will inevitably cause vibration of the auricle. This vibration will inevitably cause the Bluetooth headset to move, resulting in a shift in the position of the photoelectric sensor 4, which will interfere with the detection and analysis of physiological information. To solve this problem, the extension in this embodiment can be an electric push rod, also known as a linear actuator, used to convert the rotational motion of the motor into the linear reciprocating motion of the push rod. In this embodiment, one end of the electric push rod is fixedly installed on the headset body, and the other end extends into the ear, so that the movement of the electric push rod can drive the photoelectric sensor 4 to move, placing it in different positions inside the ear. At this time, the processor 1 is also connected to the electric push rod control, and the processor 1 is also used to drive the electric push rod according to the physiological information, so that the photoelectric sensor 4 is always in a preset position inside the ear, which is the position with the highest signal strength of the collected physiological information. Specifically, processor 1 is used to receive physiological information collected by photoelectric sensor 4 and output corresponding control signals according to the strength of physiological information. Specifically, it sends corresponding control signals based on the difference between the current strength of physiological information and the maximum strength (i.e., the strength value at the preset position). When the electric push rod receives the control signal, it drives photoelectric sensor 4 to move so that photoelectric sensor 4 is in the preset position, thereby ensuring that the highest intensity physiological information is always collected during the movement and avoiding external interference.
[0049] It should be noted that this embodiment also limits the maximum insertion depth of the electric actuator into the human ear to avoid causing danger to the human ear.
[0050] The processor 1 in this embodiment is used to determine the number of steps taken by the headphone wearer based on acceleration information. Counting steps based on acceleration is a well-established existing technology and will not be elaborated upon here. The processor determines the headphone wearer's body temperature data based on body temperature information and physiological data based on physiological information. The number of steps, body temperature data, and physiological data are then compared with their respective reference data to determine the headphone wearer's state. The headphone wearer's state can include whether they are suitable to continue exercising or not. If the number of steps, body temperature data, or physiological data exceeds their corresponding reference data, the headphone wearer's state is determined to be unsuitable for continuing exercise; otherwise, the headphone wearer's state is deemed suitable for continuing exercise.
[0051] Furthermore, the smart Bluetooth headset of this embodiment also includes a distance sensor 6 installed on the headset body. The distance sensor 6 is used to collect distance information between the headset wearer and various obstacles in the surrounding environment. The processor 1 is also communicatively connected to the distance sensor 6. The processor 1 is also used to determine the minimum distance between the headset wearer and the obstacle based on the distance information, and to control the headset body to issue a warning signal to avoid the obstacle when the minimum distance is less than a preset threshold. By setting the distance sensor 6, the minimum distance between the headset wearer and the obstacle can be detected in real time, and a warning signal can be issued when the minimum distance is less than the preset threshold, avoiding collisions between the headset wearer and the obstacle and improving safety during exercise.
[0052] The smart Bluetooth headset of this embodiment also includes a positioning chip 7 installed on the headset body. The positioning chip 7 is used to perform real-time positioning of the headset wearer and obtain positioning information. The processor 1 is also communicatively connected to the positioning chip 7, and the processor 1 is also used to generate the headset wearer's movement trajectory based on the positioning information. By setting the positioning chip 7, the headset wearer's movement trajectory can be generated and the headset wearer's movement route can be recorded.
[0053] Furthermore, the smart Bluetooth headset of this embodiment also includes a temperature sensor 8, a humidity sensor 9, and a gas detection probe 10 installed on the headset body. The temperature sensor 8 is used to collect ambient temperature information, the humidity sensor 9 is used to collect ambient humidity information, and the gas detection probe 10 is used to collect ambient gas information. The gas detection probe 10 can be a CO2 concentration sensor to collect the CO2 concentration in the environment. The processor 1 is also communicatively connected to the temperature sensor 8, humidity sensor 9, and gas detection probe 10. The processor 1 is also used to determine whether it is suitable for exercise based on the ambient temperature information, ambient humidity information, and ambient gas information, and to control the headset body to issue an alert signal indicating that exercise is not suitable when it is not suitable for exercise. By setting the temperature sensor 8, humidity sensor 9, and gas detection probe 10, it is possible to detect whether the external environment is suitable for exercise, further improving the safety of exercise.
[0054] The processor 1 in this embodiment is also used to send the number of steps, body temperature data, physiological data, movement trajectory, ambient temperature data, ambient humidity data and ambient gas data to a mobile terminal paired with the smart Bluetooth headset. The mobile terminal can monitor the wearer's physical condition and movement data as well as external environmental data in real time.

The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. Furthermore, those skilled in the art will recognize that, based on the ideas of the present invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of the present invention.
