Description

≪ Desc / Clms Page number 1 > System for wireless communication using microphone and speaker &

The present invention relates to a microphone and speaker wireless transmission / reception system, and a microphone and speaker wireless transmission / reception system having a microphone and a speaker.

Generally, a microphone is a device installed on a stage or stage of a room or outdoor, amplifies an input voice signal, and transmits the amplified voice signal to a wired or wirelessly connected acoustic device so that the audible person can hear the amplified voice through the speaker.

Wireless microphones are widely used in various event venues, lecture rooms, and karaoke rooms due to the convenience that users can freely use while moving their positions. When a wireless microphone is used in a karaoke room having several rooms, the wireless microphones used for each room are set in advance with different frequency channels.

Generally, a wireless microphone collects the voice of love into a dust collector, modulates it in the form of an FM signal, and sends out this signal through an RF transmitter. The signal transmitted through the wireless microphone transmitter recognizes the same frequency in the wireless microphone receiver and re-detects it as a voice signal from the FM signal. At this time, the detected voice signal is output through a speaker through an amplifier such as an amplifier. RF frequency wireless microphones can be communicated by setting the frequency channels of the wireless microphones and the receiving microphones in the range of 20MHz ~ 900MHz to 1: 1.

Therefore, in the case of a conventional wireless microphone, it is inconvenient to synchronize the frequencies of the transmitting end and the receiving end.

In addition, the pack type wireless microphone has a structure to be worn on the ear by using a wire. Therefore, a disconnection problem may occur and inconvenience may occur. In addition, there is an inconvenience in use because it must be used by hand.

The microphone device 100 converts an audio analog signal input from a microphone into a data format, converts the audio analog signal from the audio codec to digital data, and digitally transmits the audio analog signal through a microphone IR communication unit.

In the speaker device 200, the spatial aliasing problem is caused by a problem in the tone color because the listener moving in the listening space experiences a modulation effect with a rapid change of high frequency. Therefore, tweeter is added to the unit for loudspeaker array to solve this spatial alias. We developed a loudspeaker bar which is a disadvantage of the existing gigaphones, absorbing the loudspeaker waveform from the sponge of the loudspeaker itself, and improving the clarity of the sound and the clarity of the sound.

The speaker device 200 includes a speaker IR communication unit for performing IR communication with the microphone IR communication unit and an audio output unit for amplifying and outputting audio received through the microphone IR communication unit.
