Abstract
An acoustic block manufacturing method includes: mixing zeolite powder with water to form a mixed liquid; making the mixed liquid into an ice cube; providing a vacuum environment to make the ice cube undergo gas phase sublimation; and feeding parylene into the vacuum environment in a manner of chemical vapor deposition to form an acoustic block having a porous structure. The acoustic block can effectively reduce resonance frequency. An acoustic device with acoustic blocks is also provided and has the same effect.
