Abstract

A multifunctional Bluetooth microphone includes a handle having a microphone head formed at one end to receive a sound signal; a device mounting unit coupled to the handle to be adjacent to the microphone head, equipped with Bluetooth technology, and provided with a high-power speaker on one side; a digital signal processing unit provided in the device mounting unit to add an additional function of at least one type of echo mode or at least one type of voice modulation mode to a voice of a person by performing digital signal processing on the voice; a function input unit provided in the device mounting unit for operation of the digital signal processing unit; and a microphone controller for controlling operation of the digital signal processing unit on the basis of an input signal of the function input unit.

Claims (19)

1. A multifunctional Bluetooth microphone comprising:

a handle having a microphone head formed at one end to receive a sound signal;

a device mounting unit coupled to the handle to be adjacent to the microphone head, equipped with Bluetooth technology, and provided with a speaker on one side;

a digital signal processing unit provided in the device mounting unit to add an additional function of at least one echo mode or at least one voice modulation mode to a voice of a person by performing digital signal processing on the voice;

a function input unit provided in the device mounting unit for operation of the digital signal processing unit;

a microphone controller for controlling operation of the digital signal processing unit on the basis of an input signal of the function input unit;

an FM transmission function unit provided in the device mounting unit to mix a sound source transferred through Bluetooth with an input voice of the person for wireless expansion and then output the sound through a radio receiver by FM transmission, wherein an operation thereof is controlled by the microphone controller according to the input signal of the function input unit;

an MR removal function unit for emphasizing the voice of the person by removing chorus and accompaniment portions (MR) from the sound source transferred through Bluetooth, wherein an operation thereof is controlled by the microphone controller according to the input signal of the function input unit; and

a duet function unit for allowing, when any one multifunctional Bluetooth microphone is connected to a Bluetooth sound source in a state where two or more multifunctional Bluetooth microphones are connected through Bluetooth, all the multifunctional Bluetooth microphones to interwork and simultaneously play back the Bluetooth sound source, wherein an operation thereof is controlled by the microphone controller according to the input signal of the function input unit.

2. The microphone according to claim 1 , further comprising:

an LED display window provided on one side of the device mounting unit to output an input value of the function input unit;

an auxiliary (Aux) out terminal unit provided on a bottom of the device mounting unit for wired expansion;

a multi-USB port disposed around the Aux out terminal unit and capable of charging or data communication;

a memory card port provided on one side of the device mounting unit; and

an earphone jack provided on one side of the device mounting unit.

3. The microphone according to claim 1 , further comprising a USB light emitting lamp including a terminal coupling unit detachably coupled to the multi-USB port and emitting light when music is output, wherein

the microphone controller controls an operation of the USB light emitting lamp to be automatically turned on when the USB light emitting lamp is connected.

4. The microphone according to claim 1 , further comprising a USB light emitting rotation ball including a terminal coupling unit detachably coupled to the multi-USB port, a rotating lamp ball for emitting light while rotating, and a connection line for connecting the terminal coupling unit and the rotating lamp ball, and emitting light and rotating when music is output, wherein

when the USB light emitting rotation ball is connected, the microphone controller controls an operation of the USB light emitting rotation ball to be automatically turned on.
