Description
Technical Field
The invention belongs to the technical field of earphone diaphragms, and particularly relates to a method for preparing an earphone biological diaphragm by utilizing a natural biological material, namely fish glue.
Background
The diaphragm is a key accessory of the loudspeaker, and the quality and consistency of the diaphragm directly influence the technical index and the yield of the loudspeaker. The main function of the diaphragm is vibration, one influencing the dynamic performance of vibration is elasticity, and the other influencing the dynamic performance of vibration is inertia. The vibrating diaphragm with enough rigidity has linear elastic performance, better vibration dynamic performance and balanced audio performance, and can reasonably restore and play back sound signals; and the light vibrating diaphragm has smaller motion inertia and better sound definition and detail performance. Therefore, the material of the diaphragm is usually selected from a class of materials with low density, good rigidity and moderate damping. The vibrating diaphragm materials on the market at present comprise natural fiber materials such as paper, silk and the like, metal vibrating diaphragms and high-molecular synthetic fiber vibrating diaphragms such as polyamide, polyurethane and liquid crystal polymer, biological vibrating diaphragms and the like. The diaphragms made of different materials have the characteristics that if the polymer diaphragm is low in cost, the diaphragm is a bright spot, but the diaphragm is poor in rigidity, small in internal resistance and easy to distort; the paper diaphragm is easy to drive, has high restoration degree to sound, and has natural sound, but the sound effect is greatly influenced by the external environment; the metal diaphragm is excellent in rigidity, crisp in sound, accurate in timbre, and rich in details of high frequencies in particular, but the metal diaphragm is heavy relative to other materials and is not easy to drive the unit. The biological material diaphragm is generally light in weight and good in toughness, the earphone is good in transient and dynamic performances, and the sound is natural, soft and very resistant to hearing. However, the currently marketed biological diaphragms have limited types and higher prices, and the development of novel and various biological diaphragms can bring more various audio-visual enjoyment to people.
The application of the fish glue has been in China for thousands of years, and ancient people cohere the intelligence of ancient Chinese people by utilizing the high viscosity of the fish glue to adhere wood and furniture between one tenon and one mortise. The production process of the fish glue is well known, but the film forming property of the fish glue is not utilized all the time, the viscosity of the fish glue is very high, the adhesive strength exceeds that of the common glue, and therefore, the film after film forming has high strength and good elasticity and toughness. The main components of the health care product are collagen, gelatin, mucopolysaccharide, various vitamins and various trace elements such as calcium, zinc, iron, selenium and the like, and the components are close to the components of the human eardrum, so that the health care product is closer to the human eardrum in terms of sound reduction. Therefore, the diaphragm for the earphone must be a good choice.
Disclosure of Invention

Detailed Description
Examples
Firstly, preparing glue, namely soaking 5g of dried swimming bladder glue in clean water for 24h, crushing the dried swimming bladder glue to be less than 0.5cm by using a crusher after the soaking is softened, adding 500ml of water, heating and boiling for 1h, adding water continuously according to conditions during heating to keep water quantity to just submerge swimming bladder, and stopping heating after the swimming bladder fragments are glutinous and sticky;
secondly, smashing glue, taking out the softened swimming bladder and water, putting into a mortar, and grinding and smashing until the fragments are completely changed into viscous paste;
step three, taking the glue juice, wrapping the viscous liquid obtained in the step two with gauze of 100 meshes, and extruding the glue juice;
fourthly, concentrating, namely continuously heating the glue juice for 20min at the temperature of 100 ℃, and concentrating until the glue juice is viscous;
fifthly, forming the film, namely pouring the concentrated glue juice into a vibrating diaphragm mould with the diameter of 9.5mm while the glue juice is hot, fully contacting the mould wall, pouring out the redundant glue juice, putting the glue juice into an oven (the temperature is controlled below 55 ℃) or drying the glue juice at room temperature, taking out the dried film from the mould, and measuring the thickness to be 0.2mm and the diameter to be 9.5 mm.
The formed vibrating diaphragm is installed in the in-ear earphone, a frequency response curve is tested, the frequency response curve of background white noise and the frequency response curve of the biological vibrating diaphragm are compared, the high, middle and low audio frequency sections can be well restored by the local vibrating diaphragm, and distortion is small.
