Problems solved by technology

In the 21st century, mobile phones have become an indispensable daily necessities in people's lives. Although mobile phones have their own microphones, the microphones of mobile phones are mainly for communication. The requirements for recording are not high, and the sound cannot be restored with high quality.
In order to be compatible with more devices, the microphone requires an additional adapter cable, which is very inconvenient and unintelligent

Embodiment Construction

[0027] In order to make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects obtained easy to understand, the specific implementation manners of the present invention will be further described below in conjunction with the specific drawings.

[0028] It should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0029] Such as Figure 3-5 As shown, there are three types of TS series plugs commonly used at present.

[0030] in, image 3 Shown is the TS plug, which has 2 signal terminals, L and G. When connecting to recording equipment, usually the L terminal is connected to the audio signal of the microphone, and the G terminal is grounded.

[0031] in, Figure 4 Shown is the TRS plug, which has 3 signal terminals, L, R and G terminals. When connecting a recording device, usually the L or R terminal is connected...

Abstract

The invention discloses a microphone with an intelligent conversion interface, which comprises a microphone body, a TRRS interface device and an intelligent conversion circuit, wherein the intelligentconversion circuit is used for identifying an interface type of voice recording equipment to automatically switch an audio signal channel of the microphone; the intelligent conversion circuit comprises a detection unit and a switching unit; the detection unit is used for detecting bias voltages of signal ends of the TRRS interface device; the switching unit is used for switching among the signalends of the TRRS interface device according to a detection result of the detection unit; and the TRRS interface device adopts a plug or a socket with four ports. The invention further provides an implementation method of the microphone with the intelligent conversion interface. According to the invention, by arranging the detection unit in the microphone body, the bias voltages on the signal endsof the TRRS plug are detected, and by the switching unit, switching on connection channels between an audio signal and the signal ends of the TRRS plug is implemented; the microphone is applicable tovarious types of interfaces, integrates multiple purposes into one machine, and is convenient for a user to use.

Description

technical field [0001] The invention relates to a microphone, more precisely, to a microphone with an intelligent conversion interface and a realization method. Background technique [0002] Microphone, scientifically called microphone, is an energy conversion device that converts sound signals into electrical signals. It is transliterated from the English word "Microphone", also known as microphone and microphone. Professional microphones are mainly used for high-quality recording equipment, mainly cameras, recording pens and other professional equipment. The interfaces used by these professional devices are generally male or female sockets of three-section TRS and four-section TRRS. In the 21st century, mobile phones have become an indispensable daily necessities in people's lives. Although mobile phones have built-in microphones, the microphones of mobile phones are mainly for communication. The requirements for recording are not high, and the sound cannot be restored wi...
