Description

Thin horn structure Technical Field The utility model relates to the technical field of thin horns, in particular to a thin horn structure. Background The thin loudspeaker comprises a bracket, a voice coil and a magnetic return part, wherein the lower end of the voice coil stretches into a gap between the upper end of the U-shaped iron and an iron sheet, and a vibrating diaphragm is connected to the top of the voice coil. The inner magnetic thin horn has the characteristics of small volume, strong stability, long service life and the like. If a dustproof cap is added to the top of the traditional thin loudspeaker, the positioning difficulty is high, structural positioning deviation after assembly is easy to occur, and vibration membrane deformation is caused by uneven stress when the vibration membrane vibrates, so that harmonic distortion is generated. Disclosure of Invention In order to overcome the defects and shortcomings in the prior art, the utility model aims to provide a thin horn structure. The thin loudspeaker structure comprises a basin frame, a vibrating diaphragm and a dustproof cap covered on the top of the vibrating diaphragm, wherein the periphery of the vibrating diaphragm is annularly attached to the top of the basin frame, a first boss is annularly protruded at the bottom of the dustproof cap, a second boss is annularly protruded at the top of the vibrating diaphragm, and the first boss and the second boss are concentrically arranged and are buckled with each other. Preferably, the vibrating diaphragm is provided with an annular concave groove part, the thin horn structure further comprises an elastic wave which is annularly attached to the inside of the basin frame, and the groove part is propped against the elastic wave. Preferably, an annular limiting table is arranged in the basin frame, and the periphery of the elastic wave is attached to the annular limiting table in an annular mode. Preferably, the top surface of the dust cap is carved with CD lines. Preferably, the thin horn structure further comprises a U-shaped iron contained in the middle of the basin frame, a first magnet contained in an inner cavity of the U-shaped iron, a washer attached to the top of the first magnet, a second magnet attached to the top of the washer, and a voice coil movably extending into the inner cavity of the U-shaped iron, wherein a fixing hole is formed in the middle of the vibrating diaphragm, and the voice coil penetrates through and is attached to the fixing hole. Preferably, the bottom of the basin frame is provided with an embedded hole, the periphery of the bottom of the U-shaped iron is provided with an annular abdication groove which is propped against the inner side wall of the embedded hole, and the bottom of the U-shaped iron is fixedly connected with the embedded hole. Preferably, the periphery of the basin frame is provided with mounting holes. The thin loudspeaker structure has the beneficial effects that the basin frame, the vibrating diaphragm and the dustproof cap covered on the top of the vibrating diaphragm are adopted, the periphery of the vibrating diaphragm is annularly attached to the top of the basin frame, the bottom of the dustproof cap is annularly protruded and stretched with the first boss, the top of the vibrating diaphragm is annularly protruded and stretched with the second boss, the first boss and the second boss are concentrically arranged and buckled with each other, the dustproof cap is favorably and rapidly positioned and installed on the top of the vibrating diaphragm, the dustproof cap and the vibrating diaphragm are kept concentric after being installed, harmonic distortion caused by deformation of the vibrating diaphragm due to uneven stress when the vibrating diaphragm is caused by the eccentricity of the dustproof cap is avoided, and the assembly efficiency between the dustproof cap and the vibrating diaphragm is also favorably improved.
