Embodiment

[0022] The first step is to make gelatin. Put 5g of dried isinglass gel into clear water and soak for 24 hours. After soaking and softening, use a pulverizer to crush it to below 0.5cm. Add 500ml of water and heat to boil for 1 hour. During the heating period, according to the situation Add water one after another to keep the amount of water just enough to submerge the swim bladder, and stop heating when the broken pieces of the swim bladder are soft and sticky;

[0023] The second step is to smash the glue, take out the softened swim bladder together with the water, put it in a mortar, grind and smash until the pieces become a sticky paste;

[0024] The third step is to take the glue juice, wrap the viscous liquid obtained in the second step with 100-mesh gauze, and squeeze out the glue juice;

[0025] The fourth step is to concentrate, continue to heat the glue juice at 100°C for 20 minutes, and concentrate until the glue juice becomes viscous;

[0026] The fifth step is to...

Abstract

The invention discloses a method for preparing a biological vibrating diaphragm of an earphone through bladder glue, belongs to the technical field of earphone diaphragms, and can solve a problem thatconventional earphone diaphragm is liable to cause the distortion, is poor in detail resolution of sound, the types of the earphone vibrating diaphragms made of biological materials are limited and the price is high. The method comprises the five steps: glue preparing, glue hitting, glue liquid extraction, concentration and diaphragm forming. The method is simple in technology, and is low in cost.

Description

technical field [0001] The invention belongs to the technical field of earphone diaphragms, and in particular relates to a method for preparing an earphone bio-diaphragm by utilizing a natural biological material-isin bladder. Background technique [0002] The diaphragm is the key accessory of the speaker, and its quality and consistency directly affect the technical indicators and yield of the speaker. The main function of the diaphragm is to vibrate, one of which affects the dynamic performance of vibration is elasticity, and the other is inertia. A diaphragm with sufficient stiffness has a linear elastic performance, better vibration dynamics, and a balanced audio performance, which can reasonably restore and playback sound signals; while a light-weight diaphragm has a relatively small motion inertia, and the clarity and details of the sound are better. it is good. Therefore, the diaphragm material usually chooses a material with low density, good rigidity and moderate ...
