SMD buzzer refers to the buzzer of the plastic shell, appearance and size of smaller, roll tape packaging, the pin can be flat to the PCB, patch type package is relative to plug-in type is another form of packaging of the buzzer. The product has the advantages of small size, light weight, sound clar
From the perspective of the technological development trend of electronic components in the world, overall, chipping has become one of the important indicators to measure the development level of electronic components technology. Among them, chip capacitors, chip resistors and chip inductors are thr
A piezo buzzer is a sound producing device.The main working principle is based on the theory that, whenever an electric potential is applied across a piezoelectric material, a pressure variation is generated. A piezo buzzerconsists of piezo crystals in between two conductors.When a potential differe
If the user uses a passive piezoelectric buzzer or a passive electromagnetic buzzer, it is recommended to use 1/2 square wave in the input voltage and frequency conditions. Why use it? Because this condition can The buzzer (buzzer) inside the buzzer achieves the highest amplitude, which means that t
Bluetooth Anti-lost Device:Using bluetooth transmit distance to judge if the article is lost. Usually its valid distance is 10-25 meters. Its range is relative small.It is mainly used to anti lost.When the article with device is over valid distance,the device and mobile phone will both alarm.GPS tra
What is a Buzzer?A buzzer is a mechanical, electromechanical, magnetic, electromagnetic, electro-acoustic or piezoelectric audio signalling device. A piezo electric buzzer can be driven by an oscillating electronic circuit or other audio signal source. A click, beep or ring can indicate that a butto
An electronic component is any basic discrete device or physical entity in an electronic system used to affect electrons or their associated fields. Electronic components are mostly industrial products, available in a singular form and are not to be confused with electrical elements, which are conce
Buzzer classification:1, according to the principle of the drive mode, can be divided into: active buzzer (including drive lines) and passive buzzer (external drive);2, according to the different structure, can be divided into: electromagnetic buzzer and piezoelectric buzzer;3, according to the diff
When we go to the hospital, patients will be measured blood pressure and body temperature, but the data collected only once a year or two years, and often will be ignored.It will not attact attention until these results deviate from normal value.However, the thoughts and plan of biomedical researche
The global market for Electronic Components is projected to reach US$191.8 billion by 2022, driven by the increasing indipensability of electronics in modern life; continuous development of consumer,industrial,automotive and defense electronics; shorter product lifecycles and a parallel increase in
Most consumer electronics are built in China, due to maintenance cost, availability of materials, quality, and speed as opposed to other countries such as the United States. Cities such as Shenzhen have become important production centres for the industry, attracting many consumer electronics compan
Wireless Charging provides a convenient, safe, and reliable way to charge and power millions of electrical devices at home, in the workplace and in industry.By eliminating the use of physical connectors and cables, wireless charging provides a number of efficiency, cost and safety advantages over th
