Mechanical frequency division diaphragm and manufacturing method thereof

Abstract

The invention relates to a mechanical frequency division diaphragm, which is provided with at least one slit for dividing the mechanical frequency division diaphragm. An adhesive for softly connecting the divided parts of the mechanical frequency division diaphragm is filled in the slit. The invention also relates to a manufacturing method for the mechanical frequency division diaphragm. The manufacturing method comprises the following steps of: performing slitting machining on the mechanical frequency diaphragm to manufacture at least one slit for dividing the mechanical frequency division diaphragm; and filling the adhesive in the slit to softly connect the divided parts of the mechanical frequency division diaphragm. In the mechanical frequency division diaphragm and the manufacturing method thereof provided by the invention, own amplitude frequency response of the diaphragm is regulated to weaken an undesired high-frequency part by changing own vibration mode of the diaphragm of a loudspeaker, so that processing is not required to be performed on acoustical signals not arriving at the diaphragm to further avoid all possible distortions, simultaneously achieve a frequency division effect and overcome the shortcoming of influence on original sounds in conventional frequency division methods.

Description

technical field [0001] The invention relates to the field of audio, more specifically, to a mechanical frequency-dividing diaphragm and a manufacturing method thereof. Background technique [0002] The frequency range of the sound that can be heard by the human ear is 20 to 20KHZ, but often a speaker cannot reproduce the sound of such a wide frequency range, so in order to achieve better sound effects, we often use 2 or more One or more speakers are responsible for the high-frequency part, such a speaker is called a mid-range speaker; plus one or more speakers are responsible for the reproduction of the low-frequency part, such a speaker is called a mid-bass speaker. Of course, the replay of the sound realized by these two kinds of speakers overlaps in the middle frequency band. In order to prevent the sounds of these two kinds of speakers from affecting each other, frequency division is required, that is, the mid-bass speaker does not reproduce the high-frequency sound, so ...

AI Technical Summary

Problems solved by technology

Either method will have an impact on the original sound, especially the second one, which will cause a large phase shift, resulting in the amplitude-frequency response of the final speaker playback becoming unsmooth, resulting in larger and deeper valleys or deeper High peaks, so the heard sound will be very different from the original sound
