Time flies. 2023 Chinese New Year is coming soon. Thank you very much for your support to FBelec in the past year, FBELE Spring Festival holiday arrangement in 2023 is as follows:

1. Our engieer and salesteam will be on holiday from 2023, Jan, 21th---2023, Jan, 27th. but still one Salesman will be on Duty.so if you have something urgent, you can write E-mail to us During these days! we can still quota!!

2. Our workers will be Holiday 2023, Jan, 6th---2023, Feb,10. but from 2022, Dec.30th...there will be less full production capacity---Until---2023,Feb,20th.....then production will recover again little by little. but you can still request some urgent order. Maybe we can try or find other solution...or even we have stock for some products!

3. If you have order.please send it A.S.A.P to avoid any delay.

FBele looks forward to more cooperation with you~

  dia 21.5mm 4.0KHZ frequency double side piezo element with braided wire

  FT-21.5T-4.0ASL1

  FBelec has developed a new type of double-sided piezo element, including piezoelectric vibrating plate and sound film. A first power lead is welded on the metal plate part of the piezoelectric vibrating plate, and a short circuit is provided on one side of the piezoelectric vibrating plate. A copper sheet, the short-circuiting copper sheet includes a connecting portion provided with a mounting hole, a first crimping portion and a second crimping portion extending outward from one side of the connecting portion, and the first crimping portion and the second crimping portion The outer ends of the crimping part are respectively welded on the silver electrodes of the piezoelectric ceramic plate part on the corresponding side of the piezoelectric vibration plate, and the second power lead is welded on the connecting part. It solves the problem of "reducing the double-sided buzzing" It has a series of advantages such as low product failure rate, good product structure stability and long product service life.Best Piezo Round Bimorph in China.

  dia 23.5mm 2.7KHZ frequency double side piezo element with braided wire

  FT-23.5T-2.7ASL

  Fabrication method of piezoelectric bimorph: piezoelectric diaphragms is an electronic product that uses the piezoelectric effect of piezoelectric ceramics to work and sound. It has the advantages of low power consumption, low cost, high reliability, anti bad working environment and less vulnerable to electromagnetic interference. It is widely used in the fields of household appliances, mechanical equipment, automobile anti-theft, home security and so on. The structure of piezoelectric buzzer sheet is to paste piezoelectric ceramic sheet on metal substrate (generally copper sheet or stainless steel sheet), and silver paste is printed on both sides of piezo disc as electrode material. When the high-frequency AC signal is loaded on the buzzer, the piezoelectric ceramic sheet produces the corresponding regular geometric deformation due to the piezoelectric effect, which drives the metal substrate to vibrate and produce sound

  How to turn the piezo UNIMORPH to the maximum? piezoelectric plate is not about dB, but about frequency. There are several types of 35 copper chips. If the frequency of the acoustic element is consistent with the frequency required by your product, the sound will be louder. It can be said that you can play its performance only by taking your seat according to the number! The sound of the alarm mainly depends on the matching of inductance and Piezo Benders, and is considered from the aspects of inductance, capacity and frequency In addition, the colloid cover of the horn is also the key. The copper sheet used for Piezoelectric Ceramic Chips is divided into thick sheet and thin sheet. The sound of thick film will be thicker, and the sound of thin film will be sharper! So aside from other factors, it is meaningless to say the volume of Piezo-Electric Diaphragm alone!

  27mm 3.9KHZ brass piezo ceramic element with wire and connector

  FT-27T-3.9A1LC

  soldering method of Piezo Benders: As we all know, the piezoelectric ceramic plate can be welded. Let's summarize the welding method of the unimorph piezoelectric membrane. First, you need to apply a voltage to the Piezo-Electric Diaphragm using a wire. If using a soldering iron, the best temperature for soldering the wires to the sheet metal is 300°C for a few seconds.For ceramic electrodes, the same temperature value should be used, and the time should be 0.5 seconds or Shorter. The wire used should be as thin as possible, such as AWG32, because its function is to limit oscillation as the load of the piezoelectric ceramic . Secondly, the solder joint on the ceramic electrode should be as small as possible, and a thinner solder wire can be used, because more solder acts as the load of the piezoelectric ceramic buzzer, which will also affect the oscillation. FBelec's welding technology is unanimously recognized in the industry.

  FT-31.8T-3.2A1W

  About the three-pin boost inductance of the Piezo buzzer DiaphragmThe driving circuit of the piezoelectric ceramic buzzer is only 3V because it uses a button battery, and a three-pin boost inductor is used. The driving waveform is a 5.1Kz square waveThe questions as below: 1. What principles should the boost inductor work follow to design? Is it according to resonance?2. The parameters currently selected for the boost inductor. The driving current is fast 30mA during operation, and the button battery can not stand it. Is there any basis for parameter design? The number ratio of front and rear? Inductance ratio? Secondary inductance value?If you want to get the answer, please contact the engineers of FBelec

  35mm brass piezo ceramic element with 48mm PVC

  FT-35-3.0A1 with PVC

  How about the quality of the piezo element with PVC Diaphragm? FBelec supplies 35mm copper piezoelectric diaphragms pasted with 47mm PVC film welding wire, Piezo Ceramic Generator, tram alarm piece, high temperature resistant material or ordinary material, which can be made into conical or flat film. The length of welding wire can be customized, and the color of wire can be various colors, including red, blue, black, yellow, etc. Piezo Ceramic Bimorph can also be self excited or other excited. Glue dispensing at the welding position can prevent the welding wire from falling off! Quality assurance! If necessary, you can also apply green oil on the surface of the Piezo-Electric Diaphragm to prevent the oxidation of the piezo UNIMORPH after a long time and affect the use!

  35mm green internal piezo element with wire and connector

  FT-35S-32S8W75

  The working principle of the Piezoelectric Ceramic Chips:The sound source of the sound element of the Piezo Ceramic Bimorph mainly comes from the piezoelectric vibration plate. The piezoelectric vibration plate consists of a piezoelectric ceramic plate with electrodes printed on both sides and a metal plate (brass or stainless steel, etc.). Using adhesive, the piezoelectric vibration plate and the metal sheet are bonded together, which is what we commonly call the buzzer sheet. Typically, piezoelectric vibrating plates are installed in resonant chambers to generate high sound pressure. Most buzzer chips in China are produced by FBelec, FBelec will always be your first choice

  Sound capability of piezoelectric elements: Piezoelectric buzzer is designed to enable product manufacturers to produce sound in their own shell and shell design, FBelec has special professional knowledge and more than 20 years of production experience in the production of piezoelectric components, ranging from 10mm size for sensors to very large units for alarms. The specially formulated piezoelectric ceramic disc is suitable for various base disc materials to adapt to most applications. Piezoelectric disc is a low-cost and low-power solution, which can produce good sound output in specific medium and high frequency band. When combined with a plastic cone or layered in a bimorph structure, the piezoelectric sheet can become a very powerful sound generator.
