Abstract

Disclosed is a wireless MIC system for automatically paring, which comprises a wireless MIC which includes a paring button at its one side and facilitates a connection mode as it is automatically paired with an amplifier by transmitting a paring request signal when the paring button is on, and initializes a connection related information stored in a storing part when the connection mode is cancelled and converts an acoustic signal into a digital audio signal and transmits to the paired amplifier; and an amplifier which facilitates a connection mode as the wireless MIC and the amplifier are paired by setting a transmission and receiving channel of the amplifier and the wireless MIC, and amplifies a digital audio signal from the wireless MIC and outputs in an acoustic form.

Claims

1. A wireless MIC (microphone) system for automatically paring, comprising:

a wireless MIC which includes a paring button at its one side and facilitates a connection mode as it is automatically paired with an amplifier by transmitting a paring request signal when the paring button is on, and initializes a connection related information stored in a storing part when the connection mode is cancelled and converts an acoustic signal into a digital audio signal and transmits to the paired amplifier; and

an amplifier which facilitates a connection mode as the wireless MIC and the amplifier are paired by setting a transmission and receiving channel of the amplifier and the wireless MIC, and amplifies a digital audio signal from the wireless MIC and outputs in an acoustic form.

2. The system of claim 1, wherein said amplifier comprises:

a plurality of wireless receiving chips which receive a paring request signal and a digital audio signal from the plurality of the wireless MICs; and

a channel process part which allows each wireless MIC to transmits a digital audio signal by using a transmission and receiving channel based on an advanced adaptive frequency hopping method when digital audio signals are transmitted from the plurality of the wireless MICs.

3. The system of claim 2, wherein said amplifier comprises:

a howling inhibition circuit which judges whether a howling has happened by detecting a change of a digital audio signal from a wireless MIC, and eliminates a howling by adjusting a gain value of a digital audio signal when it is judged that a howling has happened.

4. The system of claim 3, wherein said amplifier comprises:

a plurality of input terminals which are formed at one side of the amplifier and receive a digital audio signal or a digital image signal from an external input device.

5. The system of claim 4, wherein said amplifier comprises:

a tone adjustment input part which receives a command on a tone adjustment;

a volume adjustment part which receives a command on a volume adjustment;

a tone adjustment circuit which modulates a digital audio signal from the wireless MIC into a corresponding frequency for thereby adjusting to a certain tone value when a request for adjusting a tone is inputted from the tone adjustment input part; and

a volume adjustment circuit which adjusts a digital audio signal from the wireless MIC to a certain volume valve when a request for adjusting a volume is received from the volume adjustment input part.

6. The system of claim 1, wherein said wireless MIC comprises:

a paring button which receives a command on a paring with an amplifier;

a central processing unit in which a paring request signal is transmitted to an amplifier when an on signal is received from the paring button, and a pin code of a wireless MIC is transmitted for a paring between the devices when a paring approval signal and a pin code of an amplifier are received from the amplifier by transmitting a paring request signal to the amplifier, and an acoustic signal is converted into a digital audio signal in the connection mode as the devices are paired and, and is transmitted to a paired amplifier; and

an initialization circuit which initializes by deleting a pin code information exchanged between the devices when a connection mode with the amplifier paired with the wireless MIC is cancelled.

7. The system of claim 6, wherein said wireless MIC comprises:

a USB input terminal which is installed at one side of the wireless MIC and receives a DC voltage of a computer; and

a charge process part which charges with a DC voltage inputted via the USB input terminal.

8. The system of claim 7, wherein wireless MIC comprises:

a LED installed at one side of the wireless MIC;

a LCD installed at one side of the wireless MIC;

a charge state judgment part which judges a charge state of a charge battery of the wireless MIC;

a connection state judgment part which judges a connection state between the wireless MIC and the amplifier; and

an information provision part which allows a result of the judgment of the charge state judgment part and the connection state judgment part to be outputted via the LED or the LCD.

9. The system of claim 8, wherein said wireless MIC comprises:

an alarm part which process to output a charge suggestion message via the LED and the LCD when a charge level is below a previously set level as a result of the judgment of the charge state judgment part and processes to transmit a short message (SMS) informing a charge suggestion to a user of the wireless MIC.
