With the deepening of the acoustic market demand, the market demand for acoustic equipment is growing. Especially in the field of scientific research projects, noise detection, etc., the demand for simple operation and surface microphones has increased significantly. This kind of microphone has become the first choice of many users because of its efficient performance and convenient operation. In this context, Beijing Allinby as a long-term focus on the microphone field of national enterprises, with its years of research and development experience and technology accumulation, actively respond to market demand, invested a lot of resources for the surface microphone research and development work. Through the unremitting efforts and careful polishing of the R&D team, the development, trial production and mass production of surface microphone UVP47 have been successfully completed. At present, UVP47 has been officially listed after passing the metrology certification of the China Institute of Metrology.

Product overview

UVP47 surface microphone is a special microphone independently developed by our company. It adopts integrated design, built-in preamplifier, and adopts IEPE power supply mode without polarization voltage. It can be used in wind tunnel noise test, automobile and aircraft surface noise test and other scenarios. Its compact structure makes it easy to install on automotive or aircraft surfaces. The diaphragm of the microphone is flush with the housing, which can minimize the wind noise of the microphone. The microphone pressure equalization vent is located next to the vibrating film on the front of the microphone, and the static pressure can change rapidly depending on the location when the microphone is exposed to turbulent pressure fluctuations.
