Classroom-used wireless mic system for automatically paring

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.

Description

technical field [0001] The present invention relates to a wireless microphone system for classrooms that can be automatically paired, and in particular to a wireless microphone that transmits a pairing invitation signal when the pairing button is pressed to be automatically paired with an amplifier; the amplifier receives the pairing invitation signal from the wireless microphone, Then set the signal transmitting and receiving channels of the amplifier and the wireless microphone, so that the wireless microphone and the amplifier are paired with each other. Therefore, when the user presses the open button, the wireless microphone and the amplifier are automatically paired with each other, thereby providing the user with the possibility of convenience. Automatic pairing of wireless microphone systems for classroom use. Background technique [0002] The invention relates to an automatic matching wireless microphone system for classrooms. [0003] The wireless microphone syste...

Problems solved by technology

[0009] However, the previous method requires users to pair wireless devices one by one, which is inconvenient

For example, in a tutoring classroom with multiple classrooms, in order for the teacher to use his own microphone to give lectures in each classroom, he needs to pair with the wireless speakers installed in each classroom every time he lectures, which is inconvenient to use.

[0010] In addition, when the microphones installed in the classrooms transmit signals through wireless communication, there may be noise (noise)

In particular, the closer the distance between the microphone and the wireless speaker, the more severe the howling phenomenon will be. When howling occurs, low-frequency oscillation sounds similar to noise will be continuously generated, making it difficult to convey the sound.
