Abstract

The invention discloses a manufacturing method and application of an insulating layer for an electrostatic ultrasonic transducer, and the manufacturing method comprises the steps: manufacturing a corresponding UV jet printing pattern according to a target parameter of a to-be-manufactured target insulating layer, configuring a corresponding UV jet printing machine parameter according to the target parameter of the to-be-manufactured target insulating layer, performing UV jet printing on a pre-manufactured conductive substrate based on the UV jet printing machine pattern and the UV jet printing machine parameters to obtain a target insulating layer; according to the manufacturing method, the UV jet printing pattern and the UV jet printing machine parameters are set based on the target parameters of the target insulating layer, UV jet printing is carried out to obtain the target insulating layer, and the obtained target insulating layer has high transparency and high breakdown-resistant voltage so as to be suitable for products with high requirements for the overall transparency of the electrostatic ultrasonic transducer; and the application field of the electrostatic ultrasonic transducer is effectively expanded.

Description

technical field [0001] The invention relates to the technical field of ultrasonic transducers, in particular to a manufacturing method and application of an insulating layer for electrostatic ultrasonic transducers. Background technique [0002] With the continuous development of display device technology, the requirements for the integration of the display panel and the sound generating device in the display device are getting higher and higher. However, the traditional MEMS (Micro-Electro-Mechanical System, Micro-Electro-Mechanical System) process structure is difficult to realize the integrated design with the display panel. In order to achieve a high degree of integration, current display devices usually use electrostatic ultrasonic transducers, and finally form ultrasonic directional screen products. [0003] Electrostatic ultrasonic transducer refers to "a transducer that uses electric field force to vibrate the diaphragm to emit ultrasound". It is a new type of ultra...
