Described retainer ring is a copper ring.
Described shell upper end is provided with front sound mouth, and described T iron below is provided with a pcb board, and described T iron and pcb board centre position place are provided with rear sender.
The axial cross section of described T iron is T character contour.
The beneficial effects of the utility model are: a kind of earphone horn structure, comprise speaker body, speaker body comprises shell, voice coil loudspeaker voice coil, vibrating membrane, magnet ring, T iron, washer, retainer ring, voice coil loudspeaker voice coil is arranged on vibrating membrane below, vibrating membrane edge is fixed on retainer ring, magnet ring is arranged on the bottom of T iron and around lug boss, voice coil loudspeaker voice coil inserts the clearance space between magnet ring inwall and lug boss outer wall, be that magnet ring is arranged on voice coil loudspeaker voice coil outside, the end difference place magnet ring that retainer ring is arranged on outer casing inner wall is pressed on the bottom surface of retainer ring, washer is arranged on magnet ring top and is pressed on the inwall of retainer ring, locate respectively the vertical and horizontal level of retainer ring by magnet ring and washer, in washer and magnet ring joint, between outer casing inner wall and magnet ring outer wall, inject respectively sealing glue and form fluid sealant water layer, the structure of loudspeaker that the utility model has passed through external magnetic type design simplification, dwindle the diameter of loudspeaker, make loudspeaker diameter can accomplish 6mm or below 6mm, and by guaranteeing the sealing between vibrating membrane and magnetic circuit at washer and magnet ring joint injection sealing glue, between wall and magnet ring outer wall, inject in the enclosure sealing glue and guarantee the sealing between vibrating membrane and shell, avoid the phenomenon that leaks air, ensure the low frequency loudness of loudspeaker and reduce distortion.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is generalized section of the present utility model.
embodiment
With reference to Fig. 1, Fig. 1 is the axial section structural representation of a specific embodiment of the utility model, as shown in the figure, a kind of earphone horn structure, comprise speaker body, described speaker body comprises shell 1, voice coil loudspeaker voice coil 2, vibrating membrane, magnet ring 3, T iron 4, washer 7, described vibrating membrane comprises the first vibrating membrane 51 and the second vibrating membrane 52, described the first vibrating membrane 51 is arranged on voice coil loudspeaker voice coil 2, described the second vibrating membrane 52 inner sides are arranged on voice coil loudspeaker voice coil 2 edges, described the second vibrating membrane 52 arranged outside are on a retainer ring 6, in the present embodiment, this retainer ring 6 is a copper ring, described T iron 4 is for to be made up of electrical pure iron, its axial cross section is T character contour, it comprises a bottom 41 and a lug boss raising up 42, described magnet ring 3 is arranged on the bottom 41 of T iron 4 and around lug boss 42, between described magnet ring 3 inwalls and lug boss 42 outer walls, there is a clearance space, described voice coil loudspeaker voice coil 2 is inserted into this clearance space, be that magnet ring 3 is arranged on voice coil loudspeaker voice coil 2 outsides, for external magnetic type designs.
