The utility model discloses a horn adopting double moving coil units. The horn comprises a low pitch unit and a high pitch unit. The low pitch unit and the high pitch unit are overlapped. The low pitch unit comprises a low pitch unit diaphragm. A central section of the low pitch unit diaphragm is set to be an approximately flat-topped type. Through integrating and arranging the low pitch unit and the high pitch unit, the sound emitted by the horn using the above structure is rich in a high frequency, a low frequency and an intermediate frequency. A relatively-individual all frequency unit effect is increased obviously. Simultaneously, the central section of the low pitch unit diaphragm is set to be the approximately flat-topped type. On one hand, an integral thickness of the low pitch unit can be reduced; on the other hand, through a concrete design parameter of the central section of the low pitch unit diaphragm, a high-frequency cutoff frequency of the low pitch unit can be adjusted so that an effect of mec
