Abstract

The invention provides a card insertion type microphone. A play module is integrated on a circuit board of the microphone, a body of the microphone is provided with a card slot and a music play button, the card slot is connected with the internal circuit board, and the microphone is connected with an external loudspeaker box. According to the card insertion type microphone, the card slot capable of reading an SD card is arranged on the body of the microphone, the microphone is connected with the external loudspeaker box, the functions of playing music and amplifying sound are realized, the structure of the microphone is simple, the same functions are realized under the condition that the microphone does not depend on excessive equipment, and the dependency of the microphone is greatly reduced, thereby being favorable for the all-round popularization on the market.

Description

technical field [0001] The invention relates to a microphone, in particular to a card-insertable microphone. Background technique [0002] A microphone is a microphone, also known as a microphone, which is a transducer that converts sound into an electrical signal, and has the function of amplifying the sound. Microphones are used in many occasions, such as venues, stages, KTV rooms, etc. If the current microphone needs to realize the function of singing, it is generally connected to an external audio device through a connecting cable of the microphone. Audio equipment includes speakers, power amplifiers, CD / VCD / LD / DVD players, etc., which often cost a lot, have high requirements for purchasing power, and have a lot of equipment, which is complicated to operate, expensive to maintain, and takes up a lot of space. . The above-mentioned deficiencies make the microphone more dependent in use. Contents of the invention [0003] The purpose of the present invention is to pr...
