External KTV guiding/antiphonal singing switching device, system and communication protocol

Abstract

The invention discloses an external KTV guiding / antiphonal singing switching device, a system and a communication protocol, wherein the device comprises a first audio frequency detection circuit, a second audio frequency detection circuit, a microprocessor, a first audio frequency input interface which is used for connecting a first microphone, a second audio frequency input interface which is used for connecting a second microphone, and a serial port circuit which is used for connecting KTV entertainment equipment. The external KTV guiding / antiphonal singing switching device, the system and the communication protocol provided by the invention are capable of communicating with the existing low-level KTV entertainment equipment, so that the KTV equipment without a guiding / antiphonal singing switching function can have the guiding / antiphonal singing switching function, the guiding / antiphonal singing functions can be added at any time according to the demands of equipment manufacturers, and the waste of the replaced low-level KTV entertainment equipment during the upgrading of the low-level KTV entertainment equipment is avoided while the generality of the equipment is enhanced. Moreover, as general interfaces are used for plugging, the device has the advantages that the mounting is simple, convenient and reliable in practical use.

Description

technical field [0001] The invention relates to the field of electronics, in particular to an external KTV guide and antiphonal switching device, system and communication protocol. Background technique [0002] On KTV entertainment equipment, the function of "guiding and singing duet" is a special electronic audio technology, and many high-end KTV entertainment equipment support this function; , including accompaniment and vocals)" and "accompaniment (song accompaniment only, without vocals)" are two special terms, while "guide-singing duet" is a more intelligent and humanized version of the "original singing accompaniment" function. extension. [0003] The function of "guiding and singing duet" needs certain hardware support. For the KTV entertainment system without "guiding and singing duet" hardware equipment, it cannot support the function of "guiding and singing duet". However, due to the high price of the high-end KTV entertainment system with the function of guiding...

Problems solved by technology

[0003] The function of "guiding and singing duet" requires certain hardware support. For KTV entertainment systems without "guiding and singing duet" hardware equipment, it cannot support the function of "guiding and singing duet"

However, due to the high price of the high-end KTV entertainment system with the function of guiding and singing duet, when the low-end KTV entertainment system without hardware equipment supporting the function of guiding and singing duet needs to be upgraded in a KTV place, if the high-end KTV entertainment system is directly used to directly replace the original low-end equipment, then the replaced low-end KTV equipment will cause idle waste
