Problems solved by technology

[0002] The paper cone, that is, the sound cone, is an important part of the speaker. In the speaker, the voice coil will vibrate strongly in the magnetic field after being connected to the audio signal. The voice coil is fixed on the paper cone, and the vibration of the voice coil drives the paper at the same time. The vibration of the basin, the vibration of the paper cone forces the air to vibrate, thereby making a sound, so the quality of the paper cone has an absolute impact on the sound quality of the speaker. In the prior art, most speakers have good bass sound quality, but poor treble sound quality, or The high-pitched sound quality is good, but the low-pitched sound quality is poor, and it cannot perfectly display various sounds. The paper cone has good fidelity and is expensive. The traditional paper cone structure has poor stability, low elastic rate, poor fatigue resistance and other factors. Poor fidelity, poor sound quality from speakers

Embodiment 1

[0022] Take out 40 parts of sisal pulp, 20 parts of flax pulp and 10 parts of fluff pulp according to the weight ratio of 4-2-1, remove the hard lumps and impurities, and carry out dust cleaning treatment, and soak them separately for 30 minutes. Permeability shall prevail. When dipping, the liquid level should exceed the pulp surface, and water shall be added in due course. Put hot water at 75°C in a clean tank, add 1 part of rosin while stirring the hot water, and add cold water to lower the solution temperature after emulsification. Lower the temperature to 30°C and set the volume to the specified concentration. Put an appropriate amount of water into the beater, turn on the power, shred the impregnated wood pulp, and put them into the beater one by one to decompose. After decomposing for about 5 minutes, stop the machine and dig out. Re-start the machine to defuse the pulp that has stopped at a dead corner, and then deflate again for 3 minutes, then take a small amount of t...

Embodiment 2

[0025] Take out 45 parts of sisal pulp, 22.5 parts of flax pulp and 11.3 parts of fluff pulp according to the weight ratio of 4-2-1, remove the hard lumps and impurities, and carry out dust cleaning treatment, respectively impregnated for 40 minutes, all impregnated with pulp When soaking, the liquid level should exceed the surface of the pulp, and water should be added in time. Put 80°C hot water in a clean tank, add 1 part of paraffin while stirring the hot water, and add cold water to lower the solution temperature after emulsification. Lower the temperature to 35°C and set the volume to the specified concentration. Put an appropriate amount of water into the beater, turn on the power, shred the impregnated wood pulp, and put them into the beater one by one to decompose. Stop the machine after decomposing for about 8 minutes. Re-start the machine to defuse the pulp that has stopped at a dead corner, and then deflate again for 4 minutes, then take a small amount of the deflat...

Embodiment 3

[0028]Take out 40 parts of sisal pulp, 20 parts of flax pulp and 10 parts of fluff pulp according to the weight ratio of 4-2-1, remove the hard lumps and impurities, and carry out dust cleaning treatment, and soak them separately for 50 minutes. Permeability shall prevail, the liquid level shall exceed the pulp surface during immersion, and water shall be added in time, and hot water at 85°C shall be put in a clean tank, and 2 parts of acrylic polyester waterproofing agent shall be added while stirring the hot water, and all emulsified before adding Lower the temperature of the solution to 40°C with cold water and set the volume to the specified concentration. Put an appropriate amount of water into the beater, turn on the power, shred the soaked wood pulp, and put them into the beater one by one for about 10 minutes. After that, stop the machine, dig out the pulp lumps that have stopped in the dead corner, and restart the machine to defuse it. After thawing again for 5 minutes...

Abstract

The invention discloses a high-fidelity loudspeaker cone and a production process thereof. The cone comprises components in parts by weight as follows: 30-45 parts of sisal pulp, 10-25 parts of flax pulp, 5-15 parts of fluff pulp and 0.5-2 parts of carbon fiber powder. The cone production process comprises following steps: S1), material preparation: the sisal pulp, flax pulp and fluff pulp are taken out in the weight ratio, lumps and impurities are removed, dust cleaning treatment is performed, and soaking is respectively performed for 30-50 min. According to the high-fidelity loudspeaker coneand the production process cone thereof, mixed pulp of the sisal pulp, flax pulp and fluff pulp is used as a main material of the cone to provide rigidity and toughness of the cone, so that the elasticity of the cone is improved; the carbon fiber, bulletproof fiber and glass fiber are used as compound ingredients to ensure the strength of the cone, so that the stability of the paper cone is improved; the edge of the cone is soaked with glue, solder alloy is used for attaching to avoid flaking, the elasticity and fatigue resistance of cone are improved, and the tone of a loudspeaker is better.

Description

technical field [0001] The invention relates to the technical field of paper cone and its production, in particular to a high-fidelity horn paper cone and its production process. Background technique [0002] The paper cone, that is, the sound cone, is an important part of the speaker. In the speaker, the voice coil will vibrate strongly in the magnetic field after being connected to the audio signal. The voice coil is fixed on the paper cone, and the vibration of the voice coil drives the paper at the same time.
