Why some buzzers don't make sound before being assembled?
There are some indexes to help choose buzzers.
1. LCP is applied as housing material with properties including heat resistance and acid-alkali resistance2. Well-chosen yellow grass is applied as lead pin material in order to provide best welding property to the product.3. Tiny size of the product adapts to more multiple PCB space design.It meets

What is the diffenence between a loudspeaker and a buzzer?
How to distinguish passive buzzer and active buzzer?
Decibel(Abbr.dB) is mainly used to measure the intensity of sound. In general, dB is used to express the sound pressure level, the sound pressure is doubled and the sound pressure is increased by 6 decibels.The "cent" refers to a tenth, the ones are "shellfish", but generally only use decibels.The s
Buzzer is mainly used as warning tone and alarm sound.
Following is the notes which are suitbale to both of the two kinds of piezo buzzer.
SMD Magnetic BuzzerAdvantages: 1.The volume of buzzer can be made very small.(Length and width can be made as 4MM). It can save lots of space. 2.Its sound is the highest in same volume product.Differences: 1.Current consumption is higher than SMD piezo buzzer(Common operating c
Bluetooth beacons are hardware transmitters - a class of Bluetooth low energy (LE) devices that broadcast their identifier to nearby portable electronic devices. The technology enables smartphones, tablets and other devices to perform actions when in close proximity to a beacon.Bluetooth beacons use
The piezo buzzer is uses the piezoelectric ceramics to trade for the sound electricity can the material acoustic component, is composed of the piezoelectric vibrator and the accompaniment shell. Piezoelectricity buzzer and the past commonly used each kind of mechanical type and the electromagnetism
