Ear return 3D printe

  There are many 3D printers that are expensive
Are there any 3D printers that give people the impression that they are very expensive a few years ago? Very powerful
What can I play? Practical? Not too clear
The z-axis layer thickness of Ningbo Zhizao digital technology's 3D printer reaches 5μ m
This is a layer thickness with high accuracy, which can be almost ignored, and the plane accuracy reaches 25-mu; m。
When the low-frequency horn propagates the low-frequency sound, factors such as filtering and sound condensation are the key to whether the low-frequency sound is true or not
Through research in the acoustic laboratory, it is found that when the low-frequency sound passes through the sound guide tube with different thickness, the sound change is very small, but when the radius of the sound guide tube is small to a certain extent, the low-frequency will have no change before
In addition, when the low-frequency sound passes through the spiral sound guide tube, snake sound guide tube, square sound guide tube, etc
, the frequency response curve will produce some functional or irregular changes, resulting in great differences in listening sensation

This experiment not only achieved results on the low-frequency sound guide tube, but also found many unimaginable discoveries on the medium-frequency and high-frequency sound guide tubes
I believe this is of great significance to the development of the whole audio industry

Headphone 3D printer is not only a private customization for the ear canal, but also a customization for the designer's appearance, but also a better internal practicability for the coordination of acoustic impression
3D printing headphones will be an important milestone for made in China to become created in China, not limited to mold, not limited to mass production, change the traditional high cost and low efficiency, and focus on the design of headphones
