Detailed Description

The present invention will be further described with reference to the following examples and accompanying drawings.

As shown in fig. 1, the device may be directly connected to an audio device or a microphone.

The utility model provides an equipment of pronunciation real-time conversion characters, includes audio input processing circuit, HUB circuit, the USB interface, remote controller control circuit, LED drive circuit, LED lamp. The signal of the external sound is simultaneously sent to the audio input processing circuit and the LED driving circuit; the audio input processing circuit performs signal processing and then sends the processed signal to the HUB circuit; the HUB circuit is connected with a computer through a USB interface; and after receiving the voice signal of the sound equipment, the LED driving circuit drives the LED lamp to work. The LED driving circuit is connected with the USB interface, and the USB interface supplies power to the LED lamp. The remote controller receiving circuit is in communication connection with the HUB circuit and the audio input processing circuit.

The LED pilot lamps have three, indicate respectively whether to connect successfully with the pickup equipment, whether equipment can normally work, whether equipment and computer connect successfully.

The circuit can be replaced with an audio signal level indicating circuit according to the actual scene requirement, and the amplitude and the variation of the input audio signal level can be synchronously indicated by using the on and off of a plurality of LED lamps, as shown in FIG. 5, the audio signal level indicating circuit is provided.

Specifically, as shown in fig. 4, the remote controller control circuit is a JYD8165 chip.

Specifically, as shown in fig. 2, the audio input processing circuit is a JYD851S chip.
