Description
技术领域 technical field
本实用新型涉及耳机设计领域,尤其是一种智能蓝牙心率耳机。 The utility model relates to the field of earphone design, in particular to an intelligent bluetooth heart rate earphone.
背景技术 Background technique
蓝牙，是一种支持设备短距离通信(一般10m内)的无线电技术。能在包括移动电话、PDA、无线耳机、笔记本电脑、相关外设等之间进行无线信息交换。利用“蓝牙”技术，能够有效地简化移动通信终端设备之间的通信，也能够简化设备与因特网Internet之间的通信，从而数据传输变得更加迅速高效。蓝牙采用分散式网络结构以及快跳频和短包技术，支持点对点及点对多点通信，工作在全球通用的2.4GHzISM(即工业、科学、医学)频段。其数据速率为1Mbps。采用时分双工传输方案实现全双工传输。 Bluetooth is a radio technology that supports short-range communication (generally within 10m) of devices. It can carry out wireless information exchange between mobile phones, PDAs, wireless headsets, notebook computers, and related peripherals. The use of "Bluetooth" technology can effectively simplify the communication between mobile communication terminal devices, and also simplify the communication between devices and the Internet, so that data transmission becomes more rapid and efficient. Bluetooth adopts distributed network structure, fast frequency hopping and short packet technology, supports point-to-point and point-to-multipoint communication, and works in the globally common 2.4GHz ISM (ie industrial, scientific, medical) frequency band. Its data rate is 1Mbps. A time-division duplex transmission scheme is adopted to realize full-duplex transmission.
目前蓝牙技术在日常生活中应用最广的就是蓝牙耳机,蓝牙耳机最大的特点就是便携性和无线操作性。例如,戴上蓝牙耳机,用户可以边写邮件边讲电话、可以边开车边讲电话、可以边做家事边讲电话,而不受恼人电线的牵绊。由于蓝牙耳机的电磁波远比手机低,讲电话时只要将手机放在公文包内或是口袋里,戴上耳机轻松讲,既不用将手举得老高,还能够有效减少电磁波对人体的影响。 At present, the most widely used Bluetooth technology in daily life is the Bluetooth headset. The biggest feature of the Bluetooth headset is portability and wireless operability. For example, wearing a Bluetooth headset, users can talk on the phone while writing emails, talking on the phone while driving, or talking on the phone while doing housework, without being tied down by annoying wires. Since the electromagnetic waves of bluetooth earphones are far lower than those of mobile phones, when talking on the phone, just put the mobile phone in the briefcase or pocket, wear the earphones and talk easily, without raising your hands high, and can effectively reduce the impact of electromagnetic waves on the human body .
随着人们生活生活水平的提高,人们越来越关注自己的身体健康。现实生活中，往往会存在以下的问题：传统医疗检测费用昂贵，操作繁琐，等待时间长以及少有时间去医院的问题。随着智能产品技术领域的快速发展,智能手表、智能手环以及高性能医疗保健设备与智能穿戴产品呈现于人们面前，也为人们解决了生活上的诸多不便。对于智能蓝牙耳机,现有技术中,也开始考虑对其植入保健性功能应用,如体温、脉搏、紫外线以及脉搏等,但与智能手表和智能手环不同的之处在于,智能手表或手环采用腕带式接触,为其检测或侦测提供的便利条件。对于智能产品针对心率的侦测,主流的方式有两种:一种是利用光反射的测量、一种是利用电势的测量。前者主要为光电传感测量方式,后者为电极传感测量方式。光电测量方式目前主要能测量的是心率与血氧指标,而电极式测量的指标更全面一些，可以直接测量心电图。而电极式测量的不足之处在于：需要使用者有意识地去测量,而不能自动不间断测量并上传数字,更不能实现远程监控。 With the improvement of people's living standard, people pay more and more attention to their health. In real life, there are often the following problems: traditional medical testing is expensive, the operation is cumbersome, the waiting time is long, and there is little time to go to the hospital. With the rapid development of smart product technology, smart watches, smart bracelets, high-performance medical and health care equipment and smart wearable products have appeared in front of people, and they have also solved many inconveniences in people's lives. For smart bluetooth earphones, in the prior art, it has also begun to consider implanting health-care functional applications, such as body temperature, pulse, ultraviolet rays, and pulse, etc., but the difference from smart watches and smart bracelets is that smart watches or smart bracelets The ring adopts wristband contact, which provides convenient conditions for its detection or detection. For smart products to detect heart rate, there are two mainstream methods: one is to use the measurement of light reflection, and the other is to use the measurement of electric potential. The former is mainly a photoelectric sensing measurement method, and the latter is an electrode sensing measurement method. At present, the photoelectric measurement method can mainly measure the heart rate and blood oxygen indicators, while the electrode measurement indicators are more comprehensive, and can directly measure the electrocardiogram. The disadvantage of electrode measurement is that it requires the user to measure consciously, but cannot automatically and continuously measure and upload numbers, let alone realize remote monitoring.
现有的测心率产品中，相比于手表、手环，耳机测心率还是有天然的优势的，耳朵离心脏近血液新鲜，耳朵中又有颈内动脉系统和丰富的毛细血管，测量数据更为准确。现有的耳机测心率采用的方案为：耳机紧贴耳道形成封闭空间，由于耳膜的振动，耳道内会产生一定的压力，并且压力随着振动的改变而改变，利用麦克风采集耳道内压力的变化信息，从而达到检测心率，对于上述技术方案而言，该心率测量误差率大，设计复杂。同时，现有其他的技术方案有些光电型检测脉搏设备主要是使用红外光来测量血液，其设计在一定程度上受限。现有一种双绿色LED型反射式光电传感器，检测经过人体血液和组织吸收后的反射的光强度测心率，为可佩戴式智能电子产品以及新式测试方法大范围使用提供可能。 Among the existing heart rate measurement products, compared with watches and wristbands, earphones still have natural advantages in heart rate measurement. The ear is close to the heart and the blood is fresh. The ear has the internal carotid artery system and rich capillaries, and the measurement data is more accurate. to be accurate. The existing earphone heart rate measurement scheme is as follows: the earphone is close to the ear canal to form a closed space, due to the vibration of the eardrum, a certain pressure will be generated in the ear canal, and the pressure changes with the change of the vibration, and the microphone is used to collect the pressure in the ear canal. Change the information to achieve heart rate detection. For the above technical solution, the heart rate measurement error rate is large and the design is complicated. At the same time, some photoelectric pulse detection devices in other existing technical solutions mainly use infrared light to measure blood, and their design is limited to a certain extent. There is a dual-green LED reflective photoelectric sensor that detects the reflected light intensity absorbed by human blood and tissue to measure heart rate, which provides the possibility for a wide range of wearable smart electronic products and new testing methods.
