Method for making jadeized giant clam nacre nanopowder and loudspeaker diaphragm

Abstract

The present invention discloses fabricating methods of jade tridacna nacreous nano powder and speaker diaphragm, the fabricating method of the speaker diaphragm comprises the steps of preparing tridacna paper pulp, pouring the paper pulp onto a basin-shaped net-like mold, such that the tridacna paper pulp is deposited on the basin-shaped net-like mold, papermaking after the tridacna paper pulp is deposited with a thickness of 2 mm, drying the deposits after papermaking by warm air at 120 DEG C for 15-35 minutes and forming a speaker diaphragm after hot-pressing into the thickness of 20 micrometers by a titanium metal mold at 260 DEG C and curing for 120-160 minutes. The diaphragm of the present invention is made of a combination of jade tridacna nacreous nano powder and base paper pulp. The diaphragm can rapidly absorb the energy transversely transferred by voice and also can vibrate longitudinally to make sound rapidly. The cone breakup resonance caused by the high portion of audio frequency is sufficiently reduced and the cutoff band of roll-off also becomes smooth. The speaker made of the diaphragm is penetrating and mellow in sound, clear in details of music and good in fidelity.

Description

technical field [0001] The invention relates to the technical field of loudspeakers, in particular to a production method of jadeized giant clam nacre nanopowder and a loudspeaker diaphragm. Background technique [0002] Loudspeakers are electro-acoustic transducers that can convert electrical signals into acoustic signals and radiate them into the air. They are widely used in communication, broadcasting, education and daily life. The diaphragm is one of the most important components of the speaker, and its function is to radiate sound. The material of the diaphragm has a crucial impact on the radiation characteristics, sound quality, tone, and timbre of the speaker. The application of new materials will often fundamentally change the sound effect of the speaker. The basic requirements for the material of the speaker diaphragm are: 1) The density of the diaphragm material should be as low as possible to ensure that the speaker has a high sensitivity; 2) The specific elastic ...

AI Technical Summary

Problems solved by technology

Due to the advantages of a long history, mature and stable technology, low density, natural timbre, and large design freedom, paper diaphragm materials dominate among many diaphragm materials. Other diaphragm materials are difficult to form or immature and unstable due to processing technology, etc. so that its use has certain limitations

[0004] However, no matter the speaker made of the paper diaphragm or other materials on the market, there are defects such as the sound is not transparent enough, the sound is not round enough, the music details are not clear enough, and the fidelity is not ideal enough when playing music.
