The object of the present invention is to provide a megaphone for solving at least one of the problems of the prior art mentioned above.

The utility model adopts the following technical scheme:

the megaphone comprises a horn cylinder body, wherein the horn cylinder body comprises a large horn cylinder, a middle horn cylinder and a round bottom, the large horn cylinder, the middle horn cylinder and the round bottom are of an integrally formed structure, the middle horn cylinder is a cylindrical cylinder, the diameter of the middle horn cylinder is the same as the minimum diameter of the large horn cylinder, the round bottom is arranged between the large horn cylinder and the middle horn cylinder, and a circular groove is formed in the middle of the round bottom; the megaphone also comprises a reflecting tube, wherein the reflecting tube comprises a small reflecting tube, a large reflecting tube and a connecting part which are integrally formed, the large reflecting tube is sleeved outside the small reflecting tube, the end parts of the large reflecting tube and the small reflecting tube are connected through the connecting part, and a fixing part extends outwards from the outer side wall of the large reflecting tube; one end of the small reflection tube is inserted into the groove, and the horn cylinder and the reflection tube are fixedly connected with the round bottom through the fixing portion.

Furthermore, the large reflecting tube and the small reflecting tube are both in a horn shape, and the end with the large diameter of the small reflecting tube is connected with the end with the small diameter of the large reflecting tube.

Furthermore, the connecting parts are a plurality of connecting sheets which are uniformly distributed in the circumferential direction.

Furthermore, a round trademark sheet is attached to one end, with a small diameter, of the large reflection tube.

The utility model has the advantages as follows:

1. the utility model discloses the big section of thick bamboo of well loudspeaker, a section of thick bamboo and round bottom are the integrated into one piece structure in the loudspeaker, consequently, there is not any gap between the big section of thick bamboo of loudspeaker and the round bottom, little reflecting tube, big reflecting tube and connecting portion are the integrated into one piece structure, only need insert circular recess with the tip of little reflecting tube during the equipment, can play limiting displacement, rethread fixed part fixed connection is to the round bottom, before adopt artifical mode with little reflecting tube and big reflecting tube to assemble respectively on the round bottom, need twice installation, present little reflecting tube and big reflecting tube integration only need assembly, save half assembly process and time, the cost of labor has been saved greatly, and the production efficiency is improved.

2. The utility model discloses well big reflecting tube and little reflecting tube are loudspeaker forms, and the one end that the diameter of little reflecting tube is big is connected with the little one end of diameter of big reflecting tube, and sound gets into and carries out the one-level through little reflecting tube after the megaphone and enlarge and make it get into big reflecting tube through the reflection of trade mark piece and carry out the second grade and enlarge, and enlarge and the reflection process is smooth, and sound wave energy loss is few, and the public address is effectual.
