A sound source intelligent switching device and switching method thereof

Abstract

The invention provides an intelligent sound source switching device and switching method. The intelligent sound source switching device comprises a digital signal interface, signal mixers, effective value calculation devices, a microcontroller and a sound source selector. The digital signal interface includes a plurality of sound source interfaces for connection of various sound sources. The signal mixers are used for mixing left sound channels and right sound channels of the sound source signals connected by the sound source interfaces and outputting sound signals obtained by mixing. The effective value calculation devices receive the sound signals sent by the signal mixers corresponding to the effective value calculation devices and carry out calculation to obtain effective values of the sound signals. The microcontroller receives the effective value sent by each effective value calculation device and thus determines whether the effective value calculation device is connected to the sound source channels corresponding to the sound signals. The sound source selector obtains the determination results and then switches the output of the intelligent sound source switching device to the corresponding sound source channels to connect the corresponding sound sources. Therefore, audio playing equipment can carry out sound source switching automatically, thereby substantially improving intelligence of the audio playing equipment and simplifying the operation process of the user.

Description

technical field [0001] The invention relates to the technical field of audio equipment, in particular to a sound source switching device and a switching method. Background technique [0002] With the improvement of people's living standards, audio playback equipment has become a necessity in people's daily life. Audio playback equipment is a general term for audio input and output equipment, and it includes many types of products, which can generally be divided into: power amplifiers, speakers, multimedia consoles, digital mixers, audio sampling cards, synthesizers, mid-high frequency speakers, Microphone, PC (Personal Computer, personal computer) sound card, earphones, etc., other peripheral audio equipment: professional microphone series, earphones, PA system, etc. [0003] At present, in traditional audio playback equipment, such as power amplifiers, speakers, etc., there are often several audio sources input at the same time. There are two main methods for switching the...

AI Technical Summary

Problems solved by technology

[0004] From the above description, we know that these ways of switching audio sources are effective, but manual intervention is required during use, which is very inconvenient; for example, people need to approach the device to complete the specified switching action, or need to find a remote control to perform operation to switch, etc.

With the continuous improvement of people's demand for simplification and intelligence in the use of equipment, and the continuous development of technology, it is obvious that this method of switching audio sources in traditional audio playback equipment can no longer meet people's needs.
