Embodiment 1

[0014] Embodiment 1: A voice teaching assistant sound reinforcement system and method thereof with wake-up and refreshment functions. The microphone pickup in the neck-worn wireless transmitter can pick up the voice of the teacher during the speech and broadcast the signal; the auxiliary line input can be linked to the teacher's voice. The audio interface of computers, players and other teaching equipment is used to broadcast audio signals, and the three signal sources of voice storage module, microphone pickup and auxiliary line input are sent to the audio processing module for mixing processing, and the module performs infrared Transmit code, transmit infrared signal through the wireless signal transmitting module, transmit the mixed and processed audio signal to the sound reinforcement master station "B" in a wireless form, and then receive it by the ceiling wireless receiver / infrared wireless receiver in the sound reinforcement master station B The module is used to receive...

Embodiment 2

[0015] Embodiment 2: The difference between this embodiment and Embodiment 1 is: through the "wake up / refresh" function button in the transmitter, the audio storage module, the microphone pickup, and the auxiliary line input as the signal source, wherein the audio storage module can store in advance Voice, sound effects, music and other audio files, after being triggered by the "wake up / refresh" button, the audio signal will be broadcast, and the microphone pickup can pick up the teacher's voice for signal broadcast; the auxiliary line input can be connected to the teacher's computer, player and The audio interface of other teaching equipment is used to broadcast audio signals, and the AUX IN audio input module connects the audio signal of the neck-worn wireless transmitter "A" through the ceiling wireless receiving / sound reinforcement master station B, and sends it to the audio decoding and processing module ; After the module decodes the audio signal, it passes through the ch...

Abstract

The invention discloses a voice teaching-aided sound amplification system with wake-up and refreshing functions and a method thereof. The system comprises the following systems: a wireless transmitter, wherein the wireless transmitter is provided with a wake-up/refreshing function key; a ceiling wireless receiving/sound amplifying master station which comprises an infrared wireless receiving module; and a ceiling sound amplification auxiliary station C. The voice teaching assistance sound amplification system comprises the following steps: 1, wearing a wireless transmitter A on the neck of a teacher; 2, hoisting a signal receiving and ceiling wireless sound amplification (master station) B at the top of the classroom; 3, hoisting a signal receiving and ceiling sound amplification (auxiliary station) C at the top of the classroom; 4, using composition modes of the system are divided into A + B combination or A + B + C combination. The system solves the problems that an existing teaching sound amplification system is complex in composition, small in sound transmission range, tedious in wiring, low in stability and inconvenient to wake up trapped students quickly.

Description

technical field [0001] The invention relates to the technical field of infrared audio transmission and teaching sound reinforcement, in particular to a voice teaching assistant sound reinforcement system with wake-up and refreshment functions and a method thereof. Background technique [0002] Loudspeaker: Same as "loudspeaker". It means to amplify the sound and spread it farther. According to the use method, it can be divided into wired loudspeaker and wireless loudspeaker. At present, teachers usually use loudspeakers to assist teaching in the daily teaching process. Existing loudspeakers or sound reinforcement systems are mainly composed of loudspeakers, power amplifiers, mixers, and wireless / wired microphones, and the system is relatively complicated. The present invention fully integrates the above-mentioned devices into two types of devices, the transmitter and the receiver, and adopts infrared transmission, which saves the cumbersome wiring and greatly simplifies the...
