MP250-E

Crystals have long been used in the world of electronics and electrical engineering. From the first use of natural quartz crystals in radios to modern day semiconductors, crystals are essential components in various electrical devices. Low-Pressure Microphone MP250-E is an example of the essential role that crystals play in such devices. This article will discuss the application field and working principle of the MP250-E.

The MP250-E was designed by Moog Music, Inc. as a low-pressure microphone for a variety of electrical applications. It is used in many commercial and private applications, such as recording studios and live sound reinforcement. It is built with a special sound transducing membrane, made of quartz crystal, which is able to accurately capture sound vibrations up to 20 kHz. The MP250-E membrane is connected to an external amplifier, which amplifies the signals generated by the vibration before transmitting them to a recording device.

The working principle of the MP250-E is based on the piezoelectric effect of quartz. When an external force is applied to a quartz crystal, it produces an electrical charge which is proportional to the applied force. This electrical charge is then amplified and transmitted to a recording device. This is the same principle which is used in other piezoelectric devices, such as microphones and sounders, but the MP250-E is unique in its use of a quartz crystal membrane.

The MP250-E is extremely sensitive and can accurately capture sound vibrations up to 20 kHz. It also has a high signal-to-noise ratio, which allows it to capture sound details even at very low levels of sound pressure. This makes it ideal for recording studio and live sound reinforcement applications, where high sound pressure is not always possible. In addition, the MP250-E is relatively small, which makes it easy to integrate into other devices.

The MP250-E is an example of the important role that crystals play in the world of electronics. Its use of a quartz crystal membrane allows it to accurately capture sound vibrations while also having a high signal-to-noise ratio. It is an essential piece of equipment in many recording studios and live sound reinforcement applications. Its small size and durability make it ideal for integration into other devices.
