Description

Technical Field

[0001] The invention relates to the technical field of wireless earphone accessories, and in particular to a conductive earplug with a physiological data collection function for a wireless earphone. Background Art

[0002] In today's era of rapid technological development, electronic devices play a vital role in people's lives and work. As a popular audio device, headphones have been used by a large number of users. However, the existing headphones have relatively single functions, mainly focusing on audio playback and calls, which are difficult to meet people's increasingly diverse needs.

[0003] As people pay more and more attention to their health, the collection and monitoring of physiological data has become increasingly critical. Although there are some specialized health monitoring devices on the market, they are often large in size, inconvenient to wear, and relatively complicated to operate, causing many troubles for users. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a conductive earplug with a physiological data collection function for a wireless headset, which solves the problems mentioned in the background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] A conductive earplug with a physiological data collection function for a wireless headset comprises a conductive plug body, the shape of the conductive plug body is adapted to the ear canal, and the conductive plug body is used to extend into the ear canal to collect brain electrical signals; the raw materials for preparing the conductive plug body include a silicone matrix, a conductive filler and a conductive polymer;

[0007] An outer protective coating is applied to the outside of the conductive plug body.

[0008] Furthermore, the conductive filler is selected from one or more of carbon black, silver nanowires, graphene and carbon nanotubes.

[0009] Furthermore, the conductive polymer is selected from any one of polypyrrole, polyaniline and PEDOT.

[0010] Furthermore, the outer protective coating is a metal coating, and the raw materials for preparing the metal coating include one or more of silver, gold and copper. The metal coating is coated on the outer wall of the conductive plug body by vacuum coating or sputtering.

[0011] Furthermore, the outer protective coating is a conductive hydrogel layer, which includes a hydrogel matrix doped with conductive particles to enhance the conductive properties of the conductive hydrogel layer.

[0012] Furthermore, the conductive plug body is in a cone shape as a whole, with the front end of the conductive plug body being a hemispherical portion and the rear end being a polygonal portion.

[0013] Furthermore, a biosensor is embedded inside the conductive plug.

[0014] Furthermore, the output end of the conductive plug is electrically connected to the headphone host, which includes a main control chip. The main control chip includes a preamplifier, a bandpass filter and an analog-to-digital converter. The preamplifier is used to amplify the collected bioelectric signals, the bandpass filter is used to remove high-frequency noise and motion artifacts, and the analog-to-digital converter is used to convert analog signals into digital signals.

[0015] Furthermore, the headset host also includes an alarm unit, which is connected to the user terminal via Bluetooth or Wi-Fi communication. The alarm unit is used to remind the user to take corresponding measures when the conductive earplug detects that the user's physiological state is abnormal.

[0016] Furthermore, the headset host also includes an audio processing module, which is used to match appropriate audio according to the EEG signal.

[0017] The present invention provides a conductive earplug with physiological data collection function for wireless earphones. Compared with the prior art, it has the following beneficial effects:

[0018] 1. Accurate physiological data collection: Through advanced conductive materials and high-precision sensors, the present invention can collect the user's heart rate, body temperature, brain waves and other physiological data in real time and accurately, providing users with comprehensive health monitoring; compared with existing health monitoring equipment, the data collection accuracy of the present invention has significant advantages. For the collection of brain waves, the present invention can accurately reflect the changes in different brain electrical states, such as the distinction between states of concentration and relaxation;

[0019] 2. Efficient data collection and transmission: The data transmission between the conductive earplugs and the headphones is stable and efficient, and can quickly transmit the collected physiological data to the main control chip of the headphones; at the same time, the headphones can transmit data to external devices in real time through Bluetooth technology, such as supporting applications on mobile phones, with fast transmission speeds to ensure the timeliness and integrity of the data; in contrast, some existing headphones that integrate simple monitoring functions have slower data transmission speeds and a higher probability of data loss or errors during transmission.

[0020] 3. Convenient wearing experience: The conductive earplugs are perfectly combined with headphones. While enjoying the audio function, users can realize physiological data collection and sound wave regulation without wearing other additional devices, which greatly improves the convenience of use. Compared with existing devices with monitoring functions, the present invention has significantly improved wearing comfort. For example, existing devices may cause obvious discomfort after long-term wearing due to their large size or complicated wearing methods. The conductive earplugs of the present invention are made of soft materials and are ergonomically designed. They can fit comfortably in the ears and will not cause discomfort even when worn for a long time. At the same time, the operation of the present invention is simpler, and users can realize various functions without complicated settings and operations.

[0021] 4. Real-time health warning: When the user's physiological state is detected to be abnormal, such as a fast heart rate, high body temperature or abnormal brain waves, the headset can issue an alarm in time to remind the user to take corresponding measures and provide real-time protection for the user's health; this real-time and accuracy is difficult to match with the existing technology. Some existing devices may have problems with delayed warnings or misjudgments due to inaccurate data. The present invention can issue warnings in a timely and accurate manner through precise data collection and an efficient processing system. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In order to solve the technical problems in the background technology, the following conductive earplug with physiological data collection function for wireless earphones is provided:

[0031] Embodiment 1

[0032] The conductive earplug with physiological data collection function for wireless earphone provided by the present invention comprises a conductive plug body 1, the shape of the conductive plug body is adapted to the ear canal, and the conductive plug body is used to extend into the ear canal to collect brain electric signals; the raw materials for preparing the conductive plug body include a silicone matrix, a conductive filler and a conductive polymer; an outer protective coating, which is applied to the outside of the conductive plug body; the outer protective coating is a metal coating 2, the raw materials for preparing the metal coating include one or more of silver, gold and copper, and the metal coating is coated on the outer wall of the conductive plug body by vacuum coating or sputtering; in order to further improve the conductive performance, the surface of the earphone rubber plug can be coated with an ultra-thin metal conductive layer (such as silver, gold, copper) to enhance the conductivity; this type of coating usually adopts vacuum coating or sputtering technology to ensure that the coating is uniform and stable. The advantage of the metal coating is that it has excellent conductive performance, which can effectively reduce the resistance of the earphone rubber plug when it contacts the skin and improve the signal quality.

[0033] In this embodiment, the conductive filler is selected from one or more of carbon black, silver nanowires, graphene and carbon nanotubes; the conductive filler can convert ordinary silicone into conductive silicone, which can not only maintain the softness of the silicone material, but also capture weak EEG signals through its internal conductive network; in addition, the silicone material has less irritation to human skin and is suitable for long-term wearing.

[0034] In this embodiment, the conductive polymer is selected from any one of polypyrrole, polyaniline and PEDOT; the conductive polymer is selected from a material with excellent conductive properties. When the raw materials for making the conductive plug are used, the conductive filler is first compounded with ordinary silicone to obtain conductive silicone, and then the conductive polymer is compounded with the conductive filler silicone. When the two are compounded, a conductive plug with high flexibility and excellent conductive properties can be obtained, so that the conductive plug can better adapt to the shape changes of the ear canal and ensure stable signal collection; in addition, the conductive polymer also has good biocompatibility and will not produce adverse reactions to the skin.

[0035] In this embodiment, the conductive plug body is cone-shaped as a whole, and the front end of the conductive plug body is a hemispherical portion 11 and the rear end is a polygonal portion 12; the conical design can adapt to ear canals of different sizes, and its conical structure provides good sealing; after the earphone is inserted into the ear canal, the outer surface of the conical rubber plug is in close contact with the inner wall of the ear canal, ensuring that the conductive material can be evenly distributed on the outer surface of the rubber plug, thereby forming a stable conductive contact; the design of the front end of the hemispherical rubber plug provides better comfort, while the polygonal rear end enhances friction and stability, preventing the earphone from falling off or sliding during wearing; the hemispherical design can reduce the local pressure in the ear canal, provide a more uniform contact area, and contribute to the stable collection of physiological signals.

[0036] In this embodiment, a biosensor is embedded inside the conductive plug body; the biosensor can monitor the user's heart rate, body temperature and other biological information, thereby increasing the signal collection range of the conductive earplug and realizing comprehensive monitoring of multiple physiological states.

[0037] Embodiment 2

[0038] The conductive earplug with physiological data collection function for wireless earphones provided by the present invention comprises a conductive plug body 1, the shape of the conductive plug body is adapted to the ear canal, and the conductive plug body is used to extend into the ear canal to collect brain electrical signals; the raw materials for preparing the conductive plug body include a silicone matrix, a conductive filler and a conductive polymer; an outer protective coating is applied to the outside of the conductive plug body; the outer protective coating is a conductive hydrogel layer 3, the conductive hydrogel layer includes a hydrogel matrix, and the hydrogel matrix is ​​doped with conductive particles, and the conductive particles are used to enhance the conductive performance of the conductive hydrogel layer; hydrogel is a kind of material with high water content and softness, which can form good contact with the skin surface and is suitable for sensitive people Group and long-term monitoring scenarios; conductive particles (such as silver / silver chloride particles) are doped into the hydrogel, so that a conductive hydrogel is obtained. The conductive hydrogel can not only reduce the electrode contact resistance, but also maintain good conductivity in a relatively humid environment, which can further enhance the collection capability of physiological signals of the conductive earplug; the conductive filler is selected from one or more of carbon black, silver nanowires, graphene and carbon nanotubes; the conductive polymer is selected from any one of polypyrrole, polyaniline and PEDOT; the conductive plug body is conical as a whole, the front end of the conductive plug body is a hemispherical part 11, and the rear end is a polygonal part 12; a biosensor is embedded in the conductive plug body.

[0039] Embodiment 3

[0040] like Figure 5 As shown, the EEG signals collected by the conductive earplugs are transmitted to the signal processing module of the headset. In order to analyze and process the EEG signals to achieve a high-quality audio experience, the following solution is given:

[0041] In this embodiment, the output end of the conductive plug is electrically connected to the headphone host, and the headphone host includes a main control chip. The main control chip includes a preamplifier, a bandpass filter and an analog-to-digital converter. The preamplifier is used to amplify the collected bioelectric signals, the bandpass filter is used to remove high-frequency noise and motion artifacts, and the analog-to-digital converter is used to convert analog signals into digital signals; the above-mentioned main control chip can perform denoising and amplification processing on the bioelectric signals collected by the conductive earplugs to facilitate subsequent further audio matching.

[0042] In this embodiment, the headset host also includes an alarm unit, which is connected to the user terminal via Bluetooth or Wi-Fi communication. The alarm unit is used to remind the user to take corresponding measures when the conductive earplug detects that the user's physiological state is abnormal; when the user's physiological state is detected to be abnormal, such as a fast heart rate, high body temperature or abnormal brain waves, the headset can issue an alarm in time to remind the user to take corresponding measures and provide real-time protection for the user's health; the conductive earplug is inserted into the ear canal, has no impact on the user's life, and fits tightly. Compared with other current biological monitoring devices, it can ensure the real-time and accuracy of biological signal collection. Some existing devices may have problems with early warning delays or misjudgment due to inaccurate data.

[0043] In this embodiment, the headphone host also includes an audio processing module, which is used to match appropriate audio according to the EEG signal; the audio processing module feeds back audio according to the EEG signal, so that the user can obtain music that matches the EEG signal. When the user's EEG signal is stable or needs sleep, hypnotic songs can be provided; when the user's EEG signal is active, music suitable for exercise can be played.

[0044] The present invention creatively proposes a design scheme that combines a conductive earplug with a headset. Conductive earplugs have unique advantages and can collect the user's physiological data very conveniently. By integrating conductive materials in the earplugs, when the user wears the earplugs, the earplugs can fit tightly against the user's ear skin, thereby accurately collecting important physiological data such as heart rate, body temperature, and brain waves.

[0045] At the same time, the "conductive earplug + earphone" of the present invention uses earphones as a carrier, and after collecting data, it also has a powerful function of sound wave regulation. This means that the user can be regulated through specific sound wave frequencies and patterns based on the collected physiological data. For example, when the user's heart rate is detected to be too fast, specific soothing sound waves can be emitted to help the user relax; when the user is in a state of fatigue, sound waves that help refresh the mind can be played.

[0046] Compared with traditional health monitoring equipment and ordinary headphones, the present invention has the following significant advantages:

[0047] 1. Easy to wear: While enjoying the audio function of the headphones, users can collect physiological data and control sound waves without wearing any additional equipment, which greatly improves the convenience of use.

[0048] 2. Real-time monitoring and regulation: Since the earplugs are always in contact with the user's ear skin, they can collect physiological data in real time and regulate sound waves in a timely manner based on the data, providing users with all-round health care.

[0049] 3. Accurate data and precise control: The conductive earplugs use advanced sensing technology to ensure that the collected physiological data is accurate and reliable, while the sound wave control function is based on scientific algorithms to achieve precise control effects.

[0050] 4. Multi-function integration: The present invention perfectly integrates the audio function, physiological data collection function and sound wave regulation function of the headset, bringing users a richer and unique user experience.
