FBELE Sound Emitters

Ningbo Best Group Co., Ltd. is a large Chinese company founded in 1997, producing products of the FBELE trademark. The company specializes in the manufacture of electromagnetic transducers, piezoelectric elements, microdynamics, transceivers and microphones, and has established itself as a reliable supplier for a long time.

Sound emitters create a clearly distinguishable sound signal of constant frequency and are used to provide signals in various applications: computer equipment, telecommunications equipment, communications equipment, weighing and cash register equipment, household and automotive electronics.

The defining parameters for the selection of sound emitters are:

• Overall dimensions. All sound emitters are devices for installation on a printed circuit board, the overall dimensions and the direction of sound output from the radiator are important factors for choosing a particular model in each use case.
• Power supply voltage – allows you to select an emitter for almost any rated voltage of the device, including for microcontroller devices with low power supply.
• The resonant frequency. The distinctness of different sound signals by the human ear is directly dependent on the frequency of the tone, respectively, making a choice in favor of one frequency or another, it is possible to determine the different accents of perception of the given sound signal and reaction to it.

FBELE sound emitters of various designs are widely represented in the assortment of our company:

FBMT series – electromagnetic radiators.
The most numerous and sought-after group of sound emitters. To use them, an external generator operating at the frequency of the radiator is required.

FBMB series - electromagnetic radiators with built-in generator.
To operate such a sound emitter, only a constant voltage source is required, which may be more convenient in some applications, for example, in analog circuits or devices with simplified circuitry.

FBPB and FBPT series are piezoelectric radiators.
They have a slightly different structure from electromagnetic radiators due to the use of a piezoelectric element in their composition. As a result, the current consumption of the radiator is significantly less than that of electromagnetic radiators, but the choice of resonant frequency is significantly narrowed.
FBPB models have a built-in generator, FBPT without a generator.
