Reed switches and Reed sensors in Wireless Microphones and Radio transmitters
Wireless Microphones convert sound into electrical signal that can then be used by other sound equipment for amplification or mixing or other. They are used in various fields starting with live recordings and concerts, the movie and music making industry, smart phones and personal computers, and even in hearing devices. The problem with mechanical switches that power these devices is that they cause crackle.
To avoid crackle at the time of turning on or off, the microphones need to sieve out unnecessary signal transients. The best way to do away with crackle is to not use the standard mechanical switches for turning the microphone on or off. This is done by mounting a reed sensor on a PCB inside the microphone, having a sliding or push unit with a magnet fitted under it. This is sure to provide crackle free operation of microphones. Unlike conventional slide switches which wear out due to repeated mechanical movements of the slide contacts, the reed sensor is actuated when the magnet is slid into place, ensures that a good contact is made, and no wear out occurs.
The Reed Switches and Sensors used in such applications need to be robust, durable and efficient in meeting a high life expectancy. Our engineers work hard in life testing our products under various conditions, and we want to ensure that the the end product has a long working life. Although we wouldn’t want to restrict our products for use in only certain applications, the recommended products for use in Wireless Microphone and Radio transmitter applications are listed below.
