Sealing structure of loudspeaker

Technical Field

The utility model relates to the technical field of speakers, in particular to a speaker sealing structure.

Background

The loudspeaker is a transducer for converting an electric signal into an acoustic signal, and the quality of the loudspeaker has great influence on the sound quality. The loudspeaker is the weakest component in the audio equipment, and is the most important component for the audio effect. Loudspeakers are of a wide variety and vary widely in price. The audio frequency electric energy makes the paper cone or the diaphragm vibrate and generate resonance (resonance) with the surrounding air through electromagnetic, piezoelectric or electrostatic effect to make sound.

The loudspeaker is a unit of electric sound conversion, and the practical product for realizing the related requirements of the optimal electric sound conversion divides the loudspeaker into a front part and a rear part by taking the outer edge of the vibrating diaphragm as a boundary, the two parts need absolute isolation and sealing to better realize the reduction of the loudspeaker to the original sound, if the two parts leak the sound, the sound is influenced.
