Description

technical field [0001] The invention relates to the technical field of human daily necessities, in particular to a microphone audio conversion device. Background technique [0002] Existing microphones convert sound into electrical signals, and then input the electrical signals into audio equipment to output sound. In order to increase the sound effect, the existing microphone generally needs to add certain sound effects, such as background sound. However, there is no existing device that satisfies the mixing requirements of the microphone. Contents of the invention [0003] The purpose of the present invention is to provide a microphone audio conversion device to solve one or more technical problems in the prior art, and at least provide a beneficial option or create conditions. [0004] The solution of the present invention to solve its technical problem is: a microphone audio conversion device, comprising: a housing, a 12V battery pack and a mixing circuit board, the ...
