Description

Earphone Technical Field The embodiment of the application relates to the technical field of electronic equipment, in particular to an earphone. Background The earphone is an energy converter, which converts the energy into audible sound waves by using a loudspeaker close to an auditory canal, and is an indispensable accessory of portable electronic equipment such as a mobile phone, a walkman, a radio and the like. Particularly, bluetooth headphones such as a real wireless stereo (True Wireless Stereo, abbreviated as TWS) headphone have become necessary for people such as young people to go out of the street because of their advantages of portability and avoidance of winding of transmission lines. Generally, an earphone includes an ear cup (also called an earplug), and at least part of the ear cup is accommodated in a concha cavity in a wearing state of the earphone, for example, in an in-ear earphone, a sound outlet portion of the ear cup extends into an ear canal in a wearing state, and other portions of the ear cup than the sound outlet are accommodated in the concha cavity. The ear bag is fixed on the ear through the inner wall of the concha cavity and the inner wall of the ear canal, thereby realizing the wearing of the earphone. However, in the related art, the ear pack of the earphone has a circular structure, and when the circular ear pack is worn in the ear, the ear pack is very easy to move or even fall due to the size, the structure and the wearing habit of the human ear, so that the wearing stability of the earphone is affected. Disclosure of Invention The embodiment of the application provides an earphone, which can solve the problem that the earphone in the related art is extremely easy to move and even drop in the wearing process. The embodiment of the application provides an earphone, which comprises an ear bag, wherein the ear bag comprises a main body part and a sound outlet part which are sequentially arranged along the propagation direction of sound in the earphone, the sound outlet part is used for being close to or positioned in an ear canal of an ear when the earphone is worn on the ear of a user, and at least part of the main body part is used for being positioned in an concha cavity of the ear when the earphone is worn on the ear of the user; the main part has second part and the first part that sets gradually along the direction of propagation of sound, and first part is connected with play sound portion, and the cross-sectional shape of second part along the direction of propagation of perpendicular to sound is configured as triangle-shaped, and the side that the second part corresponds the triangle-shaped base is used for contradicting with the tragus, and the side that the second part corresponds the triangle-shaped apex angle is used for contradicting with the tragus. According to the earphone provided by the embodiment of the application, the cross section of the second part of the main body part is triangular, and the second part of the triangular structure can be matched with the concha cavity structure, so that the bottom edge part of the triangle corresponding to the second part can be abutted against the tragus, and the top corner part of the triangle corresponding to the second part is abutted against the antitragus, so that the main body part of the ear bag is stably clamped between the tragus and the antitragus. In addition, since the triangle has stability, by setting the cross-sectional shape of the second portion of the main body portion to be a triangle, the structural stability of the second portion is improved, so that the second portion will not damage the structure of the second portion when the second portion is pressed by an external pressure such as tragus or antitragus. In a possible implementation manner, at least part of the side surface of the second part facing the tragus is configured to be a first arc surface matched with the tragus, so that on one hand, the contact area of the main body part and the tragus is increased, and therefore, the supporting stability of the tragus to the main body part is further improved, the main body part is more stable between the tragus and the antitragus, and on the other hand, the fitting degree of the main body part and the tragus is higher by setting at least part of the side surface of the second part facing the tragus to be the first arc surface, and compared with the fact that the surface of the main body part facing the tragus is set to be a plane or the like, the surface of the main body part matched with the tragus is prevented from having a corner or the like, and therefore, excessive pressing of the tragus by the main body part is avoided, and the comfort degree of the earphone in the wearing process of the earphone is improved. In a feasible implementation mode, the outer contour dimension of the second part is larger than that of the first part, on one hand, the second part is ensured to be stably clamped
