Piezo Audio Transducer VS Piezo Audio Buzzer

Audio Indicators vs. Audio Transducers

As mentioned earlier in the presentation, piezo and magnetic indicators have the driving circuitry built into the design, creating a plug and play solution. Because of this, engineers do not need to worry about building a complex circuit to drive the buzzer. The disadvantage, however, is that indicators operate on a fixed frequency, reducing the flexibility offered to achieve an alternate frequency as application requirements change. Transducers, on the other hand, do not have the driving circuit built-in, so engineers are offered a greater range of flexibility when designing their circuit. The downside comes in the fact that transducers do require an external driving signal to operate properly, potentially adding complexity and time to the design cycle.

What is Piezo Buzzer,Piezo audio indicator ?

The heart of piezo buzzers are a piezoelectric ceramic plate. Piezoelectric ceramics generate electricity when they experience mechanical force and, more important to a buzzer’s function, create force when exposed to an electric field. When the ceramic experiences an alternating voltage, the plate extends and shrinks. It is glued to a fixed metal plate so these forces cause the ceramic to flex, creating the buzzing sound.

What is magnetic buzzer ? Magnetic buzzer HCM1212X ,HCM1205X

Magnetic buzzers use a coil wrapped around a pole. A metal plate is mounted a short distance from one end of the pole. The coil creates a magnetic field in the pole which attracts the plate, but since the plate is fixed the center flexes towards the pole. As the electrical signal varies, the magnetic field varies and the plate vibrates.

Piezo buzzer Vs. Magnetic Buzzers

Buzzers are a simple and inexpensive way to allow your device to make simple sounds ranging from a click when a key is pressed to a warning tone when readings fall outside of safe ranges. We offer two technologies, piezo and magnetic buzzers, and

it’s important to understand the benefits of each before deciding on the right choice for your device.

How They Work

The heart of piezo buzzers are a piezoelectric ceramic plate. Piezoelectric ceramics generate electricity when they experience mechanical force and, more important to a buzzer’s function, create force when exposed to an electric field. When the ceramic experiences an alternating voltage, the plate extends and shrinks. It is glued to a fixed metal plate so these forces cause the ceramic to flex, creating the buzzing sound.

Magnetic buzzers use a coil wrapped around a pole. A metal plate is mounted a short distance from one end of the pole. The coil creates a magnetic field in the pole which attracts the plate, but since the plate is fixed the center flexes towards the pole. As the electrical signal varies, the magnetic field varies and the plate vibrates.

Which Is Better?

The preferred solution depends on your device’s needs. Piezo buzzers can operate at much higher voltages than magnetic buzzers can. For the same voltage piezo devices use less current. Finally, piezo buzzers put out higher sound pressure than magnetic buzzers. However magnetic buzzers have one big advantage important to manufacturers: size.

Magnetic buzzers have a much smaller footprint than equivalent piezo buzzers. This is a critical feature in mobile devices. Consumers demand smaller and smaller phones, tablets, and other electronics and many modern devices simply can’t spare the room a piezo buzzer needs. A microwave oven might work fine with a piezo buzzer but a device meant to go into a pocket is going to need a magnetic buzzer.

How the solar snake repeller works

During the day, the solar panel converts solar power into the rechargeable battery. At night, the repeller turns on automatically by the stored energy. How long the repeller lasts depends on its location, weather conditions and seasonal repellering availability.

How to use the Solar Snake Repeller

Push the Plug to top jack the set begin work ' position and put the repeller in a sunny location

If the repeller does not turn on automatically after a 6 hours charge please check the following:

1) Check the battery to ensure that they are making correct contact with the terminals.

2) Check that the repeller is placed in a sunny location and that the solar panels are facing the sun.

Replacing Battery

If the Solar Mole Repeller stops working after it has been used for a long time approx. 18 months), the battery may be beyond its lifespan. You may open the screws on the bottom of the head to change new rechargeable batteries.
