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
The terms “wearable technology“, “wearable devices“, and “wearables” all refer to electronic technologies or computers that are incorporated into items of clothing and accessories which can comfortably be worn on the body. These wearable devices can perform many of the same computing tasks as mobile
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
ElectromechanicalEarly devices were based on an electromechanical system identical to an electric bell without the metal gong. Similarly, a relay may be connected to interrupt its own actuating current, causing the contacts to buzz. Often these units were anchored to a wall or ceiling to use it as a
Buzzer selected pointsBuzzer"s type specification is many, must know first several parameters (voltage, electric current, drive type, size, connection/fixed way), certainly more importantly, the wish attains the sound (sound presses size, frequency height).Working Voltage:The electromagnetic buzzer,
In the electronic circuit board production in the initial stage, through-hole assembly to be completed entirely artificial. The first batch of the introduction of the automated machines, which can put a few simple components pin, but the complexity of the components still need to be placed by hand f
Surface-mount technology, known as the English Surface Mount Technology, referred to as SMT, which is affixed to the surface-mount components, solder to the printed circuit board provides the location on the surface of the circuit assembly technology, used in circuit board with responsibility Unprin
There can be several reasons that cause the damage of buzzer which result in soundless problem.And the following includes the most common and possible reasons.You can do an experiment and see if the following reasons will result in no sound problem.1. Cover the sound port of magnetic buzzer with adh
