NEWS & INFORMATION
Main purpose:1. Sound converter: sound converter is one of the most common applications. Like pickup, microphone, earphone, buzzer, ultrasonic depth detector, sonar and ultrasonic flaw detector of materials, piezoelectric ceramics can be used as sound converter. For example, the buzzer on children's
The process flow chart is as follows: batching - mixed grinding - pre sintering - secondary grinding - granulation - forming - plastic discharge - sintering into porcelain - shape processing - electrode - high voltage polarization - aging test.1、 Ingredients: carry out material pretreatment, remove
Let's first look at a new type of bicycle damping controller. The general shock absorber is difficult to achieve a stable effect, and this ACX damping controller provides a continuously variable damping function for the first time by using piezoelectric materials. A sensor monitors the movement of t
Commonly used piezoelectric ceramics include barium titanate system, lead zirconate titanate binary system and ternary system composed of adding a third ABO3 (a represents divalent metal ions, B represents tetravalent metal ions or the sum of several ions is positive tetravalent) compounds to the bi
Piezoelectric ceramics is a kind of information functional ceramic material piezoelectric effect, which can convert mechanical energy and electrical energy into each other. Piezoelectric ceramics not only have piezoelectric, but also have dielectric and elasticity. They have been widely used in medi
Buzzer or Beeper is an audio signaling device which may be mechanical, electromagnetic, or piezoelectric. External-driven or Internal-driven, including through hole, surface mount, wire leads, panel mount and screw terminals.The size from as small as 3.2x3.2mm to 50mm and sound pressure levels (SPL)
