- Common methods of repairing piezo buzzerWe have already done some simple analyses on the piezo buzzer, magnetic buzzer, and mechanical buzzer before. In fact, some basic knowledge about them has already been understood. It is essential for us to be damaged during use. If there is no suitable replacement and it is urgent, then could we rep
- India "hypoxia", emergency purchasing Chinese oxygen generators, full quantities of oxygen sensor to help fight epidemicIndia's epidemic prevention and control has failed, extremely "hypoxia"
- What is a mechanical buzzer ?What is a mechanical buzzer? The mechanical buzzer is a special sub-category of the electromagnetic buzzer, which consists of an oscillator, an electromagnetic coil, a magnet, a casing and etc.The mechanical buzzer is always with high impedance, DC resistance is infinite, AC impedance is also very l
- How to choose the right SMD piezo buzzer ManufacturerAre you looking to get an SMD piezo buzzer for yourself? If you are, then this article can play a role.The application of SMD buzzers is wide. If you have a demand of an SMD piezo buzzer, then you must choose the right manufacturer. This is especially important if you are buying from China.So how do
- Advantages and disadvantages of ultrasonic sensorsUltrasonic sensors have the characteristics of high measurement accuracy, stable operation, and temperature compensation. They are widely used in manufacturing, power, metallurgical measured building materials, chemicals, food, automobiles, warehousing, ships, ships, textiles, transportation, explor
- How to choose a right SMD buzzerIf you are designing various products (such as home appliances or reliable access control systems, etc.), you should choose a good quality SMD buzzer as the main way to interact with different users. As outlined by www.manorshi.com, you need to understand and master the parameters of the SMD buzzer
- Magnetic V.S. Piezo BuzzersThere are two main types of buzzers, namely magnetic buzzers and piezo buzzers. In general, magnetic buzzers are more traditional. Compared with piezo buzzers, their composition is more convenient. When a voltage is applied, the coil of the buzzer generates a viable magnetic field, which makes t
- Active buzzersAn active buzzer is a device that beeps at a preferred frequency. The device generates sound itself. This is usually the case even if no force or stable direct current is applied. If you want to buy a buzzer that emits sound without generating an oscillating signal, then this may be your best ch
- Loudness and pitch of soundLoudness and pitch of soundSound is a vibration of air.Sounder pressure level (dB) = loudness of soundAir pressure is called Sound Pressure when a sound is propagated through the air.Minimal loudness of sound perceived by a human is defined as 0dB (20μPa). Sound pressure that Manorshi’s sound compon
- Related issues about buzzer voltageActive BuzzerIf it is an active buzzer, that is, a buzzer with a drive circuit inside, the voltage used is the DC power supply. For example, the common type MSPS23A35P12 is directly driven by a 12VDC voltage.Passive BuzzerIf it is a passive buzzer, that is, an externally driven buzzer, the voltage u
