Today, with the rapid development of science and technology and society, people have more and more information in their daily life and work. Therefore, information exchange and communication between people become more and more frequent and important. The digital age has been integrated into our personal and professional lives. Audio is no exception, all this will not go backwards. As mentioned above, the market demand for digital wireless microphoneTidak diragukan lagi.
After 20 years of dedicated research and development of wireless microphone, Diesp has developed a series of digital wireless microphone products in recent years, including digital wireless microphone module, digital wireless instrument microphone, digital wireless conference microphone, and so on. Our products have attracted the attention of our peers and won the favor of many customers!
1. Apa itu digitalMikrofon nirkabel?
DigitalMikrofon nirkabel, as its name implies, is a microphone and electro-acoustic device that directly outputs digital pulse signals. Digital wireless microphone systemTerdiri dari komputer, digital, dan teknologi jaringan. Transmisi sinyal digital pada lini tidak hanya meningkatkan kualitas suara dan keandalan sistem, tetapi juga secara mendasar menghilangkan kerusakan interferensi, distorsi, frekuensi seri, dan ketidakstabilan sistem secara umumSistem mikrofon nirkabel. It makes the receiving of digital wireless microphoneLebih stabil dan pembersih suara.
2. Principle of Digital Wireless Microphone
Prinsip mikrofon nirkabel digital pada dasarnya terbentuk oleh transmisi dan menerima ".
Transmitted mainly through analog signal to digital, and then after encoding processing, then to analog signal, then through modulation, and finally through power amplification to send out.
Dan tautan penerima sedikit lebih rumit daripada itu. Terutama menerima melalui antena, kemudian memperkuat kebisingan rendah, dan menyarankan sinyal audio analog melalui pencampuran. Kemudian itu mengubah sinyal analog menjadi sinyal digital untuk meningkatkan sinyal. Setelah menyaring Kebisingan frekuensi tinggi, ia mengubah sinyal digital menjadi sinyal audio analog setelah decoding, dan akhirnya mengirimnya.
Therefore, compared with traditional wireless microphones, digital wireless microphonesAkan memiliki rasio signal-to-noise yang lebih tinggi, respons frekuensi audio yang lebih luas, ketepatan yang lebih tinggi dan kerahasiaan yang kuat.
