What you Should know about the working principle of the buzzer and the principle of parallel resistance
Buzzer News Center Home » Resources » Buzzer Knowledge What You Should Know about the Working principle of the Buzzer and the Principle of Parallel Resistance Rhere are two types of buzzers widely used in the market electromagnetic and piezoelectric. We will talk about the working principle of the buzzer today. The piezoelectric buzzer mainly consists of a multi-harmonic oscillator, a piezoelectric ceramic buzzer as shown in the figure below, an impedance matcher, a resonance box, and a housing. The piezoelectric buzzer consists of a multi-harmonic oscillator, a piezoelectric buzzer (mainly piezoelectric ceramics, as shown in the figure below), an impedance matching device, a resonance box, and a housing. The main principle is to use the piezoelectric effect of the piezoelectric ceramic to drive the vibration of the metal sheet and make a sound. Piezoelectric ceramics are actually functional ceramic materials that can convert ...
Common Quality Problems with SMD Buzzer Applications
Buzzer News Center Home » Resources » Buzzer Knowledge What Are the Common Quality Problems with SMD Buzzer Applications? SMD Buzzer The buzzer is a structured electronic device that emits the alarm tone "tick, tick, tick" and is widely used in cars, communications, white goods, medical treatment, intelligent security, and other electronic devices as a pronunciation device. The SMD buzzer is a piezoelectric buzzer with excellent BTL output and a dedicated optocoupler circuit, which has been upgraded with a new core concept and processing expertise. Active SMD buzzer Make the substance the same and all kinds of professional skills index value is a good improvement; The IC has positive frequency tracking and temperature compensation role so that the buzzer is not easy due to the transformation of the working voltage and condition temperature and cause frequency drift; Accept SOP-8 post chip package, can thoroughly ...

Unneglectable Details for Buzzer Selection and How to Increase a Buzzer Volume
Buzzer News Center Home » Resources » Buzzer Knowledge Unneglectable Details for Magnetic Transducer Selection The principle of the electromagnetic transducer is an electroacoustic device that relies on the electromagnetic effect to convert electrical energy into the vibration of the vibrating piece. When a certain frequency of electrical signal passes through the coil inside the buzzer, an alternating magnetic field is generated, and after strengthening the magnetic field through the core support in the middle of the coil, the vibrating piece on the magnet coil is pushed to vibrate. The key parameters of a general electromagnetic passive buzzer are coil resistance, rated voltage, SPL value, consumption current, voltage operating range, etc. It is very important for users to do the matching of parameters during the selection, the following is an example of how to do the matching of parameters. For example, such a buzzer ...
