Product introduction.Piezoelectric Sounders / Buzzers are sound components prepared by incorporating a piezoelectric vibration plate in a plastic case (resonator). Conventional rated voltages are 3V, 5V, 12V, 24V.
Piezoelectric sounders are sound components which generate sound suitable for use as input signals (including multi-tone, melody and so forth) without built-in oscillation circuits.
This characteristic allows them to be used in a wide range of applications. They come as the SMD type, which is optimal for small, high-density mounting, and the pin type which can be used for general purposes.
Piezoelectric buzzers are sound components which generate a monotone using a built-in oscillation circuit.
These products are optimized for operation confirmation sounds and warning sounds in household appliances such as air conditioners, washers and refrigerators.
A larger size is capable of generating higher sound pressure (louder sound).
Smaller size,low current consumption, sound press level around 75dB - 85dB.
Optimized for small devices such as blood glucose meters, clinical thermometers, photoflashes for cameras, and portable terminals.
The electromagnetic buzzer is composed of an oscillator, an electromagnetic coil, a magnet, a vibrating diaphragm and a shell. After the power is turned on, the audio signal current generated by the oscillator passes through the electromagnetic coil, causing the electromagnetic coil to generate a magnetic field. The vibrating diaphragm periodically vibrates and produces sound under the interaction of the electromagnetic coil and the magnet. The electromagnetic transducer has the same working principle as the electromagnetic buzzer, but one less oscillating circuit.
Feature:
1. Low current consumption
2. High sound pressure
3. Easy assembly
4.High quality and low price
5. For automobile use
Services provided.
1. Free samples.
2.Products can be customized according to customer needs, and we have a strong R&D team.
3.The delivery time is stable. We have nearly 200 employees and a factory building of more than 10,000 square meters.
4.We promise that the quality of all products is equivalent to samples. A complete process system and quality inspection system can ensure fewer after-sales problems and reliable product quality.
FAQ
1. How to choose piezoelectric sounders / buzzer?
First of all, we need to know whether we need piezoelectric sounders or piezoelectric buzzers. This is very simple. If the driving voltage is DC, choose piezoelectric buzzer, and if the driving voltage is AC, choose piezoelectric sounders.
Secondly, we need to know their rated voltage, resonant frequency, SPL... The most important thing is the product size you need. With these parameters, our sales can recommend products that meet your requirements.
2. Is it necessary to distinguish the positive and negative poles when installing the buzzer / sounders?
Of course it is necessary. When installing the buzzer / sounders with the + sign, be sure to connect the positive pole. If it is not installed in accordance with the signs, the buzzer may be directly damaged or the sound emitted may not meet the requirements.
3. Are they compliant with RoHS directive?
All Sound Components (Piezoelectric / Electromagnetic Sounders, Piezoelectric Diaphragms, Piezoelectric / Electromagnetic Buzzers) on our Website are compliant with RoHS directive.
4. I would like to know procurement lead time
Please contact us when you need the latest lead time information because it will be changed depend on the market condition.
5. What about the Minimum Order Quantity?
Please confirm with the sales before placing the order. If there are raw materials in stock, 1,000 pieces of a single variety are acceptable.
6.Can you provide samples?
Of course, we can provide 5 free samples, and the sample delivery time is 7-10 days.
Notice
① The products must not be washed.
② Storage Condition:
The products should be stored in the room,where the temperature/humidity is stable.
And avoid such places where there are large temperature changes.
Please store the products at the following conditions:
Temperature:-10 to +40℃ Humidity: 15 to 85% R.H.
