Description

Earphone Technical Field The utility model relates to a sound generating device, in particular to an earphone. Background Headphones (Earphones/Headphones) are audio devices that convert electrical signals into sound waves, and audio devices (e.g., cell phones, computers, players, etc.) are converted into audible sound by speakers or vibration units that are positioned close to the ears. The key function of the audio system is to provide personalized audio experience, isolate external noise or keep environment perception, and the audio system is suitable for scenes such as music, conversation, office work, sports and the like. Headphones can be broadly divided into head-wearing, in-ear, earplug, ear-hanging, etc. according to different wearing modes. The ear-hanging earphone is designed into an auricle shape and can be hung on the auricle of a user for use. In order to make the ear-hanging earphone have a richer function, people often integrate a blood oxygen and heart rate monitoring unit on the earphone so that the user can monitor his own physical condition at any time. However, because of the difference in auricle shape of each person, auricle sizes are different, the distance from the acquisition component to the back of the ear is uncontrollable after different people wear the earphone, and the phenomenon that the distance from the acquisition component to the back of the ear exceeds the effective acquisition distance of the acquisition component finally results in incapability of acquiring blood oxygen and heart rate or inaccurate acquisition results. Disclosure of Invention Aiming at the defects in the prior art, the utility model aims to solve the technical problems that the blood oxygen and the heart rate cannot be acquired or the acquisition result is inaccurate due to the fact that the distance from an acquisition component of the earphone to the back of an ear is too large in the prior art. The utility model solves the technical problem that the technical proposal adopted is that the earphone is hung on the hanging part of auricle, and the earphone comprises: The ear rack comprises an ear hanging part, a first connecting part and a second connecting part which are respectively connected with two ends of the ear hanging part, wherein the first connecting part is provided with a sounding element for sounding; The hanging part is provided with a supporting section, and any point on the supporting section can be used as the highest supporting point and is abutted with the highest point of the hanging part; and defining a connecting line from any highest supporting point to the center of the sound generating element as a first connecting line, defining a connecting line from the center of the sound generating element to the center of the monitoring element as a second connecting line, and forming an included angle between the first connecting line and the second connecting line between 114.6-135.7 degrees. The utility model has at least the following beneficial effects: And the position of the monitoring element at the second connecting part is determined by taking the supporting section and the sounding element as references, so that when each highest supporting point on the supporting section is contacted with the highest point on the auricle, the monitoring element can be as close to or attached to the auricle as possible, and at least part of the area where the auricle exists is in an effective monitoring range covered by the monitoring element. Finally, on the premise of ensuring that blood oxygen and heart rate can be accurately monitored, the earphone can be worn on ears with different shapes and sizes, and the applicable crowd is wider. Further, when the length direction of the first connecting portion is perpendicular to the horizontal plane, the projection length of the first connecting line in the vertical plane is 19.1 mm-22.7 mm. Further, when the length direction of the first connecting portion is perpendicular to the horizontal plane, an included angle between any one of the first connecting lines and the horizontal plane is between 55 degrees and 76 degrees. Further, the monitoring element has a first transmitting region, a second transmitting region, a first receiving region, and a second receiving region, each of which is receptive to light beams from the first transmitting region and the second transmitting region; The minimum distance between the center of the first transmitting area and the center of the first receiving area is 4.5 mm-9 mm; And/or the minimum distance between the center of the first transmitting area and the center of the second receiving area is 4.5 mm-9 mm; And/or the minimum distance between the center of the second transmitting area and the center of the first receiving area is between 5mm and 11 mm. Further, the monitoring element has a first transmitting region, a second transmitting region, a first receiving region, and a second receiving region, each of
