Abstract
The invention discloses a super sound wave sensor vibrating diaphragm manufacturing technology. The technology is used for manufacturing a sound wave sensor vibrating diaphragm which is super thin, super light, super sensitive and chemical corrosion resistant by using unique characteristics including super hardness, elasticity and chemical stability of amorphous alloy new materials and the good fluidity and filling performance thereof in a fusion state and further adopting a copper die with good heat conduction for die casting and moulding. The vibrating diaphragm makes the sensitivity of a sound wave sensor improved and meanwhile widens an audio frequency response range. Furthermore, the problem that the sound wave sensor sensitivity is decreased due to chemical corrosion is solved. The technology can be applied to manufacturing acoustic products such as sonar, high-end loudspeakers, microphones, etc.
Description
1. Technical field [0001] The present invention uses the unique super hardness, elasticity, chemical stability and good fluidity and filling property of the amorphous alloy new material, adopts a copper metal mold with good thermal conductivity to die-cast, and manufactures ultra-thin, ultra-light, ultra-sensitive , Chemical-resistant sonic sensor diaphragm. This vibrating membrane improves the sensitivity of the acoustic wave sensor, and at the same time broadens the audio response range, and solves the problem of the decrease in the sensitivity of the acoustic wave sensor caused by chemical corrosion. It can be applied to the manufacture of acoustic products such as sonar, high-end speakers and microphones. Its technical field belongs to acoustic materials. 2. Background technology [0002] Amorphous metals are also called liquid metals or glass metals. When the metal liquid in the molten state is cooled at an extremely fast rate (one millionth of a second), the atoms i...
