Abstract
A dedicated wireless microphone of an all-in-one machine comprises a processor, a microphone head, a frequency selecting circuit, a transmitter, a display unit, a frequency locking circuit, a rechargeable battery and a button module connected with the processor. The button module comprises an automatic frequency searching button for searching frequencies automatically and a frequency locking button for locking the frequencies, the rechargeable battery supplies electricity to the wireless microphone. When the automatic frequency searching button is triggered, the processor controls the frequency selecting circuit to search the frequencies, and searched frequency bands are displayed in the display unit. When the frequency locking button is triggered, the processor selects one frequency band displayed on the display unit through the frequency locking circuit. The microphone head is used for receiving sound signals and generating corresponding electric signals, and the processor enables the electric signals from the microphone head to be transmitted to a corresponding microphone receiver through the frequency locking circuit and the transmitter. The dedicated wireless microphone of the all-in-one machine can be matched with receivers of electrified education platforms at any classroom to be used through automatic frequency selecting and locking.
