Abstract

The invention relates to a loudspeaker structure comprising a shell that comprises a front cavity and a rear cavity; a vibration component is arranged on at least one side of two opposite sides of thefront cavity; the vibration component comprises a membrane arranged in the front cavity and a permanent magnet array arranged in the rear cavity; the permanent magnet array comprises multiple first permanent magnets arranged at intervals, the polarities of each two adjacent first permanents are opposite and arranged in a staggered manner, and a driving space is formed between each two adjacent first permanents; the membrane comprises a FPC board provided with a driving circuit, the driving circuit and the driving space are correspondingly arranged, and the current directions of the two adjacent driving circuits are opposite. After alternating current is input into the loudspeaker structure, the FPC board vibrates up and down under the magnetic field effect of the permanent magnet array, so that air vibration is caused, and sound is generated; the structure is simple; only the shell, the permanent magnet array and the membrane are needed; the processing technology is simple, and meanwhile the thickness of the loudspeaker also can be reduced.

Description

technical field [0001] The present invention relates to the technical field of horns, and more specifically, relates to a horn structure. Background technique [0002] The horn is an electroacoustic component, also called a loudspeaker, whose function is to convert electrical signals into acoustic signals. With the current trend of thinning, the size requirements for speakers are also more stringent. The horns in the prior art all drive the unit diaphragm to vibrate through the driving rod to make it vibrate and sound, and the unit diaphragm is generally a layer of organic thin film. However, the horn with this structure has a complex structure and a thicker thickness. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an improved horn structure. [0004] The technical solution adopted by the present invention to solve the technical problem is to construct a loudspeaker structure, including a housing, the housing...
