A type of sharp BCZ-16 cardioid microphone design is described which is worked within 100 ~ 10 000 Hz frequency band range,and the level difference between 90°and 0°gets 10 ~12 dB.SPL of 180 °and 0°reaches 10 ~ 12 dB.SPL of 110°,- 120°and 0°reaches 20 dB or higher.Directivity Di in the 100 ~ 10 000 Hz ranges up to- 6.7 dB above,and while using in PA system,it can ignificantly improve the acoustic gain of the system,and get good sound effects.
