1. Check the piezoelectric diaphragm: Selecting a piezo diaphragm for buzzer with good appearance and no oxidized substrate for the substrate and silver plating.2. Piezo diaphragm with tin: First, the copper/steel substrate of the piezo alarm element is tinned. Because the copper/steel substrate dis

The sound source of the piezo element buzzer is mainly from the piezoelectric diaphragm. The piezoelectric vibrating plate is composed of a piezoelectric ceramic plate on which electrodes are printed on both sides, and a metal plate (brass or stainless steel, etc.). Using a bonding agent, the piezoe

Piezo ceramic elements buzzer is in an ionic crystal, positive and negative ions.which are regularly arranged alternately to form a crystal lattice. This creates an intrinsic electric moment, a polarized charge appears on the surface of the piezo crystal, and because the piezo crystal is exposed to

The piezo disc benders buzzer is mainly divided into dipolar piezo element ,tripolar piezo buzzer and double-side film. The dipolar and tripolar piezo alarm element are also the same. Let us first talk about the double-side of circular piezo disc benders.Piezoelectric double-sided diaphragm piezo e

We are a professional factory that develops, produces and sells various types of buzzer, unimorph piezo disc benders, piezoelectric transducer, piezoelectric atomizer and piezoelectric ultrasonic distance measuring sensor. Among them, the piezo disc benders is the company's main product, and the gen

1: Why is the design frequency of the piezo diaphragm at 1~~5KHz?2: What is the relationship between the design of the piezo ceramic piece and the diameter of the piezo disc benders?3: Why choose brass and stainless steel piezo bimorph as the substrate?4: Which self drive piezo element should be sel

The electronic thermometer consists of a temperature sensor, a liquid crystal display, a button battery, an ASIC and other electronic component piezo sounder ceramic element . It can quickly and accurately measure the body temperature of human body. Compared with the traditional mercury glass thermo

1.One-way Piezoelectric sensor The structure of the piezoelectric ceramic cylinder is usually a load washer type. The figure shows a one-way piezoelectric sensor structure, which is composed of a base, a force transmitting upper cover, a chip electrode, a quartz wafer, an insulating member

Barium titanate piezoelectric ceramics Barium titanate (BaTiO3) has a high dielectric constant and a large piezoelectric coefficient (about 50 times that of a quartz crystal). The disadvantage is that the curie temperature is low (120 ° C), temperature stability and mechanical strength are n

When the piezoelectric ceramic is polarized, there is a strong residual field polarization inside the ceramic material. When the ceramic material is subjected to an external force, the boundary of the domain moves is causing a change in the polarization intensity and resulting a piezoelectric effect

What’s piezoelectric sensor The piezoelectric ultrasonic sensor is based on the piezoelectric effect of some dielectric materials, and generates an electric charge on the surface of the dielectric under the action of an external force, thereby realizing non-electricity measurement. A piezoelectric s

Piezoelectric jet printer is also called high-resolution jet printer or high-resolution image jet printer. On the integrated nozzle, 128 or more piezoelectric crystals control multiple nozzle holes on the nozzle board respectively. Through CPU processing, a series of electrical signals are output to

The ultrasonic atomizer uses electronic high-frequency oscillation (oscillation frequency is 1.7MHz or 2.4MHz, which exceeds the human hearing range, the electronic oscillation is harmless to humans and animals), and the liquid water molecules are passed through the high-frequency resonance of the p
