High-foam embedded voice diaphragm and loudspeaker

Abstract

The invention relates to the technical field of electroacoustic conversion, in particular to a high-foam embedded voice diaphragm and a loudspeaker. The invention comprises a frame body which comprises a high-foam folding ring part with a cavity in the middle, an attaching part connected to the outer ring of the high-foam folding ring part and a pressing and folding part connected to the inner ring of the high-foam folding ring part. A spherical top is arranged in a cavity in the middle of the high-foam folding ring part and embedded in the pressing and folding part, a spherical surface part protruding upwards or downwards to form an arc surface is arranged on the spherical top, auxiliary spherical surface parts protruding upwards or downwards to form arc surfaces are further arranged on the spherical top on the two sides of the spherical surface part, and the total height of the voice diaphragm is larger than the adjusting space of an original scheme. The strength of the globe roof isimproved by about 30-40% compared with that of the original scheme; the up-and-down amplitude of the loudspeaker is increased by 0.1-0.15 mm compared with the original scheme; and the high-frequencycurve of the loudspeaker is smoother than that of the original scheme without attenuation.

Description

technical field [0001] The invention relates to the technical field of electroacoustic conversion, in particular to a high-foam mosaic sound membrane and a loudspeaker. Background technique [0002] Loudspeaker, also known as "horn", is a common electro-acoustic transducer device, usually used as the sound source of the speaker, and it is the last level of sound reproduction. Its quality plays a decisive role in the restoration of sound. In recent years, with the development of sound-generating devices in the direction of miniaturization and high sound quality, the thickness of the diaphragm has gradually become thinner. Although this is conducive to improving the sensitivity and damping performance of the diaphragm, it will cause the overall strength of the diaphragm to decrease, such as flat balls. Thinning the top thickness will make the dome prone to weak strength and deformation, and will also make the flatness of the diaphragm worse, which will eventually affect the ac...

In recent years, with the development of sound-generating devices in the direction of miniaturization and high sound quality, the thickness of the diaphragm has gradually become thinner. Although this is conducive to improving the sensitivity and damping performance of the diaphragm, it will cause the overall strength of the diaphragm to decrease, such as flat balls. Thinning the top thickness will make the dome prone to weak strength and deformation, and will also make the flatness of the diaphragm worse, which will eventually affect the acoustic performance of the sounding device

Moreover, in the process of testing the performance of the diaphragm, if the strength of the dome is weak, it will lead to test failure
