active buzzer we should pay attention to what the problem?

2022-03-14

For active buzzer, in the past, many designers only considered the buzzer type, working voltage, main frequency, and overall size of these main parameters, but ignored the sound pressure, current, use temperature, pressure-flow curve, supplier Experimental data and other important content, resulting in unstable sound after use.

What should be paid attention to when welding active buzzer?

What should be paid attention to when welding active buzzer? Buzzer is divided into active and passive two kinds, the working principle is different. Here we have a detailed look: 1. active buzzer, also known as piezoelectric buzzer, by the multi vibrator, piezoelectric buzzer, impedance matching box, resonator and shell composition. The most important of these is its piezoelectric buzzer, which is a piezoelectric ceramic that can stop the conversion of electrical and mechanical energy.

What is the difference between electromagnetic buzzer and piezoelectric buzzer

2022-02-28

The buzzer is a commonly used sounding element in the design of electronic products. According to the different working principle, can be divided into electromagnetic buzzer and piezoelectric buzzer. The buzzer commonly used in the development board and the experimental board is an electromagnetic buzzer, and the difference between them lies in the working principle.

electromagnetic buzzer drive design?

2022-02-11

The electromagnetic buzzer is composed of an oscillator, an electromagnetic coil, a magnet, a vibrating diaphragm and a housing. After being energized, the audio signal current generated by the oscillator passes through the electromagnetic coil, the electromagnetic coil generates a magnetic field, and the vibrating diaphragm vibrates periodically under the interaction of the electromagnetic coil and the magnet.

The dry goods are coming, and the truth of the sound from the speaker is here!

A "speaker" is often referred to as a "horn". At present, human technology needs to convert electricity into sound waves, the most mainstream technology or "electromagnetic" way, the current market speakers are mainly designed and manufactured by electromagnetic principles.

complete qualification of a electromagnetic buzzer manufacturers?
