[0015] The technical solutions in the embodiments of the utility model will be described clearly and completely below, and obviously, the described embodiments are only some embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the utility model.
[0016] The embodiments of the utility model:
[0017] Please refer to Figure 1 and Figure 2 The four-horn loudspeaker structure of the utility model comprises a U-shaped iron 14 arranged centrally, first magnets 161 are arranged on the upper and lower sides of the U-shaped iron 14 respectively, second magnets 162 are arranged on the left and right sides of the U-shaped iron 14 respectively, first Halsil 151 are arranged on the first magnets 161, second Halsil 152 are arranged on the second magnets 162, first voice coils 131 are arranged outside the first magnets 161 and the first Halsil 151, second voice coils 132 are arranged outside the second magnets 162 and the second Halsil 152, first diaphragms 121 are arranged at the outer ends of the first voice coils 131, and second diaphragms 122 are arranged at the outer ends of the second voice coils 132.
[0018] Preferably, the first voice coil 131 is provided with a first yoke 111 outside, the second voice coil 132 is provided with a second yoke 122 outside, and the first yoke 111 and the second yoke 122 are fixed together with the U-shaped iron 14 to support and fix the first voice coil 131 and the first diaphragm 121, the second voice coil 132 and the second diaphragm 122.
