Abstract

A wireless microphone system includes a receiver device, a wireless microphone device, a transmitting unit operable to transmit an identification code and a frequency matching signal, and a reading unit. The reading unit is operable to receive the identification code and the frequency matching signal, determine whether or not the identification code corresponds to the reading unit, and enable frequency matching between the receiver device and the wireless microphone device according to the frequency matching signal when the identification code is determined to correspond to the reading unit.

Claims

1. A wireless microphone system comprising:

a receiver device;

a wireless microphone device;

a transmitting unit disposed in one of said receiver device and said wireless microphone device, and operable to transmit an identification code and a frequency matching signal; and

a reading unit disposed in the other one of said receiver device and said wireless microphone device, and operable to

receive the identification code and the frequency matching signal transmitted by said transmitting unit,

determine whether or not the identification code corresponds to said reading unit, and

enable the other one of said receiver device and said wireless microphone device to perform frequency matching with said one of said receiver device and said wireless microphone device according to the frequency matching signal when the identification code is determined to correspond to said reading unit.

2. The wireless microphone system as claimed in claim 1, wherein said transmitting unit is disposed in said receiver device, and said reading unit is disposed in said wireless microphone device.

3. The wireless microphone system as claimed in claim 2, wherein said reading unit is configured to change a microphone frequency of said wireless microphone device according to the frequency matching signal to perform frequency matching with said receiver device when the identification code is determined to correspond to said reading unit.

4. The wireless microphone system as claimed in claim 1, wherein said transmitting unit and said reading unit are configured to communicate with each other using radio frequency identification (RFID) technology.

5. A method for frequency matching in a wireless microphone system, the wireless microphone system including a wireless microphone device, a receiver device, a transmitting unit disposed in one of the wireless microphone device and the receiver device, and a reading unit disposed in the other one of the wireless microphone device and the receiver device, said method comprising the steps of:

a) transmitting an identification code and a frequency matching signal using the transmitting unit;

b) receiving the identification code and the frequency matching signal transmitted by the transmitting unit using the reading unit;

c) determining, using the reading unit, whether or not the identification code corresponds to the reading unit; and

d) enabling the other one of the receiver device and the wireless microphone device to perform frequency matching with said one of the receiver device and the wireless microphone device according to the frequency matching signal when the identification code is determined to correspond to the reading unit.

6. The method as claimed in claim 5, the transmitting unit being disposed in the receiver device, the reading unit being disposed in the wireless microphone device, wherein step d) includes:

configuring the reading unit to change a microphone frequency of the wireless microphone device according to the frequency matching signal to perform frequency matching with the receiver device when the identification code is determined to correspond to the reading unit.

7. The method as claimed in claim 5, wherein:

in step a), the transmitting unit is configured to transmit the identification code and the frequency matching signal using radio frequency identification (RFID) technology; and

in step b), the reading unit is configured to receive the identification code and the frequency matching signal transmitted by the transmitting unit using RFID technology.
