Technical Field

[0001] The utility model relates to the technical field of heart rate detection earphones, in particular to a heart rate detection earphone. Background Art

[0002] With the development of communication technology, the functions of headphones are not limited to basic functions such as listening to music and making calls. For example, heart rate detection headphones can be used.

[0003] Heart rate detection earphones integrate human biological signal functions into the earphones, and give the heart rate detection function based on the original function of the earphones.

[0004] Currently, the sensor in the heart rate detection headset contacts the user's ear blade to detect the user's heart rate information.

[0005] Heart rate detection earphones with this structure have some defects: since the structure of the ear blade part of the human ear is an irregular structure such as a curved shape, and there are relatively few capillaries in the ear blade part, the accuracy of heart rate detection is reduced.

[0006] Later, in order to increase the wearing detection function of the headset, an additional wearing sensor was added to detect whether the headset was worn, which resulted in a complex internal structure of the headset and high cost. Utility Model Content

[0007] The utility model aims to overcome the deficiencies in the above-mentioned prior art and its main purpose is to provide a heart rate detection headset which can obtain information about whether the headset is being worn and the heart rate of the user. Compared with the traditional method of using separate sensors for wearing status detection and heart rate detection, it saves costs and simplifies the internal structure of the headset.

[0015] As a preferred solution, the horizontal distance between the highest points of the heart rate sensor and the ear hook in sagittal plane projection is between 10 and 20 mm, and the vertical distance is between 5 and 16 mm.

[0016] As a preferred solution, the sound-emitting part is provided with two symmetrically arranged charging terminals, and the heart rate sensor is closer to the ear hook than the charging terminals.

[0017] As a preferred solution, the earphone body is a clip-on earphone;

[0044] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0045] like Figures 1 to 7 As shown, the heart rate detection earphone in this embodiment includes an earphone body, a main control chip arranged on the earphone body, and a photoelectric heart rate sensor 13 for detecting the heart rate of the temporal artery 311 above the tragus 31 or the artery 321 of the tragus 32. Preferably, the heart rate sensor is a photoelectric heart rate sensor 13.

[0046] When the photoelectric heart rate sensor 13 is working, it emits a beam of light toward the tragus 31 or the antitragus 32. After the blood in the temporal artery 311 above the tragus 31 or the artery 321 of the antitragus 32 absorbs the green light and reflects the red light, the photoelectric heart rate sensor 13 detects the human heart rate through the reflected red light.

[0047] The photoelectric heart rate sensor 13 is configured so that when the user wears the headset body, the photoelectric heart rate sensor 13 can abut against the temporal artery 311 above the tragus 31 or the artery 321 of the antitragus 32;

[0048] The main control chip is electrically connected to the photoelectric heart rate sensor 13 to receive and analyze the signal sent by the photoelectric heart rate sensor 13 to learn that the user has worn the earphone body and the user's heart rate information.

[0049] As shown in the figure, in this embodiment, the earphone body is an earhook earphone 10, which includes a sound-emitting part 11 and an earhook 12; the sound-emitting part 11 has a built-in speaker and a sound outlet 121 is provided at the end away from the earhook 12. The sound-emitting part 11 has a sound outlet, and the heart rate sensor and the sound outlet are located on the same side.

[0050] The ear hook 12 is configured to allow the sound-emitting part 11 to be worn near the ear canal but not to block the ear canal opening, with at least a portion of the sound-emitting part 11 extending into the concha cavity 33; the photoelectric heart rate sensor 13 is located at one end of the sound-emitting part 11 close to the ear hook 12, so that when worn, the heart rate sensor can be against the artery above the tragus 31 and can then detect the user's heart rate.

[0051] The horizontal distance between the highest points of the heart rate sensor and the ear hook 12 in sagittal plane projection is between 10 and 20 mm, and the vertical distance is between 5 and 16 mm.

[0052] It should be noted that in the fields of medicine and anatomy, the sagittal plane of the human body can be defined. The sagittal plane refers to a section perpendicular to the ground along the front-back direction of the body, which divides the human body into left and right parts; the coronal plane refers to a section perpendicular to the ground along the left-right direction of the body, which divides the human body into front and back parts. Correspondingly, the sagittal axis refers to an axis along the front-back direction of the body and perpendicular to the coronal plane.

[0053] The sound-generating portion 11 is provided with two symmetrically arranged charging terminals 14 , and the photoelectric heart rate sensor 13 is closer to the ear hook 12 than the charging terminals.

[0054] As shown in the figure, in another embodiment, the earphone body is a clip-on earphone 20;

[0055] The ear-clip earphone 20 includes a first ear-clip portion 21, a second ear-clip portion 22 and a connecting arm 23 arranged therebetween, the first ear-clip portion 21 and the second ear-clip portion 22 being connected to form an ear-clip structure, respectively, the first ear-clip portion 21 and the second ear-clip portion 22 being arranged at an angle with the connecting arm 23 so that the ear-clip earphone 20 is clamped on the auricle, the heart rate sensor is arranged on the first ear-clip portion 21 and / or the second ear-clip portion 22, so that when worn, the heart rate sensor can be against the artery 321 of the antitragus 32 and then can detect the user's heart rate.

[0056] An installation area is formed between the center points of the narrowest points of the projections of the first ear portion 21 and the second ear portion 22, which are 5 mm away from the first ear portion 21 and the second ear portion 22, and the center points of the narrowest points of the projections of the first ear portion 21 and the second ear portion 22, which are 4 mm away from the upper and lower ends, respectively. The heart rate sensor is located in the installation area.

[0057] The first ear clip part 21 is used to extend into the concha cavity 33 but not block the position of the ear canal opening, and the second ear clip part 22 is located behind the ear. The first ear clip part 21 has a built-in speaker and a sound outlet 211 is provided at the end away from the connecting arm 23, a battery is provided in the second ear clip part 22, and two symmetrically arranged charging terminals 221 are provided on the second ear clip part 22.

[0058] The key point of the design of the utility model is that it mainly detects the heart rate of the temporal artery above the tragus through the heart rate sensor. After the main control chip receives and processes the information of the heart rate sensor, it can obtain the heart rate information of whether the earphone is worn and the user. Compared with the traditional method of using separate sensors for wearing status detection and heart rate detection, it saves costs and simplifies the internal structure of the earphone.

[0059] Secondly, the fingerprint recognition module is used to improve the safety of the headset. Combined with the light-guiding part of the ear hook, it can intuitively indicate through light after correct recognition.

[0060] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
