Fig. 5 shows the location of the

charging post

24, 25 being a sound vent. The positioning area for the outside magnet to adsorb is correspondingly arranged below the sound leakage hole 25, and the positioning area is just selected at the hole opening position of the sound leakage hole, so that the sound leakage hole can be made into a plane, and the positioning effect is good.

Fig. 6a shows a horizontal cross-section of the loudspeaker 20 after mounting in the ear-piece 21, and fig. 6b schematically shows two ribs 211 on the inner wall of the housing 21 of the ear-piece (in practice, the number of ribs on the inner wall of the housing of the ear-piece is more than 2) for positioning the loudspeaker 20 against rotation. The enlarged area drawn at a in fig. 6a is shown in detail in fig. 7. Fig. 7 is an enlarged view of the rib and the groove 26 in the area a of fig. 6a, and 211 is a rib on the inner wall of the ear housing, which is not limited to the shape. Correspondingly, the loudspeaker support of the ear part is correspondingly protruded to avoid the groove 26, namely, the groove 26 with the shape and the position matched with the convex rib 211 is arranged on the loudspeaker support.

As seen in fig. 9, speaker 20 is located below speaker holder 27, speaker 20 is located by the inner periphery of housing 21 and ribs 211 on housing 21, speaker holder 27 is used to support speaker 20 and to seal speaker 20 together with housing 21.

In order to solve the technical problem that the rotation phenomenon of the loudspeaker is easy to occur to affect the acoustic sealing because the loudspeaker and the inner periphery of the ear entering shell are positioned only by the appearance, the loudspeaker support 27 and the shell 21 are jointly and fixedly provided with the loudspeaker 20, the shell 21, the loudspeaker support 27 and the loudspeaker 20 to form a sealing structure in the embodiment of the application, which is shown in fig. 4-9. The first member is partially provided on the inner wall of the housing 21. The first part is a rib 211, the rib 211 is arranged along the axial direction of the shell, and the second part is a groove 26 (see fig. 4, 6a and 7) matched with the rib in shape and position. The speaker is located below the speaker support, a groove avoiding the rib is arranged on the speaker support, the bottom surface of the groove is in contact with or has a gap with the side surface of the rib (such as the long-strip-shaped rib shown in fig. 6 b) located at the upper position, namely, the rib 211 is in clearance fit with the groove 26, and at least part of the rib 211 penetrates through the groove 26 and is in interference fit with the outer periphery ring of the speaker 20. The cooperation of the three sets of ribs 211 and grooves 26 is illustrated in fig. 6a, see the areas indicated by

reference numerals

211 and 26. Since the ribs can extend into the grooves (i.e., the side surfaces of the ribs contact the walls of the grooves), the ribs and grooves appear to coincide in a horizontal cross-sectional view. The rib and groove fit is more clearly illustrated in fig. 7, where the shape and configuration of the groove 26 and the shape and configuration of the rib 211 are more clearly seen in fig. 7.
