Microphones

SPQ2410HR5H-PD Application Field and Working Principle

Microphones are special transducers used for converting sound waves into electrical signals. They are widely used in numerous applications such as telephones, headphones, hearing aids, and microphones for broadcasting and recording. The SPQ2410HR5H-PD is a condenser microphone among the several types of microphones in the market and this article will discuss its particular application field and working principle.The SPQ2410HR5H-PD is designed for high performance condenser microphone applications where a wide frequency response and high signal-to-noise ratio are needed. It is especially suitable for professional applications such as vocabulary synthesis, automatic speech recognition, voice-activated access control, voice-over-IP telephony, and music recording. It works in an omnidirectional polar pattern to capture sound from all directions, making it a great choice for recording and broadcast multiple voices.The SPQ2410HR5H-PD is a condenser microphone. It consists of two main components: a conductive metal plate and a diaphragm. The diaphragm is an ultra-thin membrane located between the two metal plates. When sound waves come into contact with the diaphragm, it vibrates and transfers vibration to the metal plates. This movement creates a varying electrical signal, which is then amplified and converted into an electrical signal.The key to the SPQ2410HR5H-PD\'s performance is its advanced low-noise preamplifier electronics. It offers improved noise performance and extended low frequency response to capture the most subtle details in the sound. Additionally, its low distortion allows it to accurately reproduce sound, as opposed to traditional microphones which are limited in their ability to capture low frequencies.The SPQ2410HR5H-PD is designed for easy integration into audio systems which can provide either phantom power or bias voltage to the microphone. Additionally, the electronics feature a power-on indicator and a 3-way on/off/mute switch to protect the microphone and ensure optimal performance.In conclusion, the SPQ2410HR5H-PD is an advanced condenser microphone designed for professional applications. It is carefully designed to deliver a clean and accurate signal with extended frequency response and low noise. Furthermore, it is easy to integrate with phantom power or bias voltage systems and comes with a power-on indicator and a 3-way on/off/mute switch for user convenience.
