[0011] Fig. 3 is an exploded view of the structure of the double-sided loudspeaker structure of the present application. DETAILED DESCRIPTION

[0012] The technical scheme in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0013] Embodiments of the present application:

[0014] Please refer to Figs. 1 to 3 The double-sided loudspeaker structure of the present application comprises an upper yoke 1 and a lower yoke 2. The upper yoke 1 is located above the lower yoke 2. A main magnet 3 is arranged between the upper yoke 1 and the lower yoke 2. A pair of auxiliary magnets 4 are arranged on the left and right sides of the main magnet 3. Main Hals 5 are arranged on the top and bottom of the main magnet 3. Auxiliary Hals 6 are arranged on the top and bottom of the auxiliary magnets 4. An upper voice coil 7 is arranged on the top outside of the auxiliary magnets 4. A lower voice coil 8 is arranged on the bottom outside of the auxiliary magnets 4. An upper diaphragm 9 is arranged above the upper voice coil 7. The edge of the upper diaphragm 9 is fixed on the upper yoke 1.

[0015] Preferably, a gasket 10 is arranged below the main Hals 5 on the bottom of the main magnet 3. The gasket 10 is used to connect the main magnet 3 and the main Hals 5.

[0016] Preferably, a metal sheet diaphragm 11 is arranged below the gasket 10. The edge of the metal sheet diaphragm 11 is fixed on the lower yoke 2.

[0017] Preferably, the upper yoke 1, the main magnet 3, the auxiliary magnet 4, the main magnet 3 top main voice coil 5, the auxiliary magnet 4 top auxiliary voice coil 6, the upper voice coil 7 and the upper diaphragm 9 form an upper horn, the lower yoke 2, the main magnet 3, the auxiliary magnet 4, the main magnet 3 bottom main voice coil 5, the auxiliary magnet 4 bottom auxiliary voice coil 6, the lower voice coil 8 and the metal sheet diaphragm 11 form a lower horn, the upper horn and the lower horn together form a double-sided horn. The double-sided horn structure of the utility model reduces the number of magnets compared with the conventional double-sided horn, so that the height of the horn can be made lower, meets the light and thin demand of modern consumer goods, reduces the assembly process, and reduces the production cost.

[0018] The above is only an embodiment of the utility model, and does not limit the patent range of the utility model, and equivalent structures or equivalent process transformations using the utility model specification content, or direct or indirect application in other related technical fields, are also included in the patent protection range of the utility model.
