The sound of a buzzer is a kind of sound wave that is produced by a vibrating device.Frequency refers to the number of continuous cycles per second, and the frequency of measurement units is Hertz Hertz (Hz). The frequency range of human ear hearing is about 20-20khz, lower than 20Hz for the second
How we express buzzer in circuit diagram?
There are several kinds of voltage symbols used in the electroacoustic industry.

Why some buzzers don't make sound before being assembled?
Sound device is various kinds of specifications, need to know several parameters (voltage, current, drive mode, size, connection/fixed way), of course, more importantly, want a voice (sound pressure size, frequency).Buzzer manufacturers of magnetic buzzer, from 1.5 to 24 v, piezoelectric from 3 v to
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
