High-pitch loudspeaker with improved glottal catch mounting structure

Abstract

The invention provides a high-pitch loudspeaker with an improved glottal catch mounting structure, which comprises a T iron, a magnet, a washer, a glottal catch and a vibrating diaphragm. The magnet is positioned between the T iron and the washer; the T iron is provided with a center hole; the glottal catch is inserted into the center hole to be fixedly connected onto the T iron; a flexible gasket is arranged at the plane joint of the glottal catch and the T iron; the vibrating diaphragm is positioned above the glottal catch and covers the glottal catch; and a sound conduction gap is reserved between the vibrating diaphragm and the glottal catch. According to the high-pitch loudspeaker with the improved glottal catch mounting structure, which is provided by the invention, by carrying out optimization and improvement on the structure of the loudspeaker, an integral glottal catch passage and a glottal outlet are designed on the same part, and the high-temperature flexible gasket is adopted between the glottal catch and the T iron, so that high stability of an acoustics path can be ensured, an SPL curve of the high-pitch vibrating diaphragm is smooth, and sound quality of the loudspeaker is ensured.

Description

technical field [0001] The invention relates to the technical field of loudspeaker manufacturing, in particular to a tweeter with an improved throat plug installation structure. Background technique [0002] Throat plug, also known as phase plug. As one of the core components of the tweeter, the throat plug can effectively improve the frequency response characteristics, prevent standing waves and crossover distortion, make the off-axis frequency response diffusion characteristics and the axial frequency response diffusion characteristics smoother, and avoid speaker mid-range Frequent off-axis frequency response peaks and valleys prevent sound distortion. [0003] In the structure of the compression tweeter, the positional relationship between the diaphragm and the throat plug and the gap range are very important. The gap between the diaphragm and the throat plug will directly affect the SPL curve and power performance of the compression tweeter. If the gap is not properly...

AI Technical Summary

Problems solved by technology

If the gap is not properly controlled, the SPL curve will fluctuate greatly in the high frequency band, resulting in sound distortion

[0004] In the existing compression tweeter, the gap is adjusted by adding gaskets when the throat plug is assembled, but there is a thickness tolerance in the size of the gaskets, and range deviation is likely to occur during the assembly process, which cannot meet the gap range requirements; and this The structure has high requirements for assemblers, which affects production efficiency
