Although any speaker has its strengths and weaknesses, especially in a limited budget, low-priced speakers are not easy to get perfect results, but regardless of the price and leve

The application of the inverse piezoelectric effect is mainly used in piezoelectric buzzers, such as music greeting cards, doorbells. Pager. Mobile phone ringing, etc.

Generally, it is an integrated package, using high-temperature resistant materials, which can be directly soldered by wave soldering

And the active buzzer already has a circuit inside, and with an oscillation source, giving him a working voltage will make a sound,The tone (frequency) is already fixed and cannot

Ultrasound has a great ability to penetrate liquids and solids, especially in opaque solids, which can penetrate to a depth of tens of meters.

Traditional loudspeakers are used to propagate sound over a wide area: audio electrical energy emits sound through electromagnetic, piezoelectric, or electrostatic effects that vib

The main performance indicators of the speaker are: sensitivity, frequency response, rated power, rated impedance, directivity and distortion and other parameters.

Customers cannot reuse the buzzer for secondary processing (such as: plugging holes, welding enameled wire, shearing shells, etc.).
