detailed description

The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given. It should be noted that a number of variations and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention.

Example 1:

The earphone front plug structure, as shown in FIG. 1 and FIG. 2, includes an earphone front plug 1; the outer shape of the earphone front plug 1 is matched with the shape of the outer ear canal mouth of the human ear; the earphone front plug 1 is a cavity The top and bottom of the earphone front plug 1 are respectively extended upward and downward in a wing shape; the front end of the earphone front plug 1 is provided with a sound outlet 3;

As shown in FIG. 3, the earphone front plug 1 is internally provided with a cylindrical through hole 4; the cylindrical through hole 4 is fixed inside the front surface of the earphone front plug 1 and the cylindrical through hole 4 is connected to the sound output port 3. The three-sided hollow structure inside the earphone front plug 1 can make the ear canal and the front plug of the earphone have a certain downward pressing space, so that the wearing is comfortable, adapts to more people, and plays a certain soundproofing effect. ;

As shown in FIG. 4, the earphone front plug 1 includes a front surface and a rear surface that are smoothly joined; the front surface is a recessed structure 6 in the middle; the shape and position of the recessed structure 6 are matched with the human outer ear door; The outer ear door is the intersection of the external auditory canal and the ear cavity; the concave structure 6 can be abstracted as two planes intersecting, the plane angle being an obtuse angle, the angle being 95° to 150°;

As shown in FIG. 5, a sound guiding tube 5 connected to the micro speaker is fixed inside the earphone body 2, and the earphone front plug 1 and the earphone body 2 are sleeved or adhered to the cylindrical through hole 4 through the sound guiding tube 5.
