Audio optical signal path switching method and apparatus

Abstract

The invention provides an audio optical signal path switching method and apparatus. A button switch module I, a button switch module II, a microcomputer electro-optical switch, a ship-shaped rocker switching switch module, a single-side control circuit board, and two path indication lamps. When the button switch module I is started, the ship-shaped rocker switching switch module turns on the path indication lamp I; the single-side control circuit board controls the microcomputer electro-optical switch to carry out conduction of the path I. When the button switch module II is started, the ship-shaped rocker switching switch module turns on the path indication lamp II; and the single-side control circuit board controls the microcomputer electro-optical switch to carry out conduction of the path II. Therefore, random switching of dual paths is realized. According to the invention, for communication between audio devices using optical fibers for audio signal transmission, a path switching problem during two-to-one communication is solved; rapid and precise dual-path switching can be realized simply, conveniently, and rapidly only by pressing the buttons of the apparatus and the path conduction state is maintained after power off of the apparatus, so that energy conservation and environment protection can be ensured. The provided method and the apparatus have high practical values.

Description

Problems solved by technology

[0003] The technical problem solved by the present invention is to provide a method and device for switching audio and optical signal paths, aiming at communication between audio equipment using optical fiber to transmit audio signals, solving the problem of path switching during many-to-one communication, especially two-to-one communication, By pressing the button on the device, the two channels can be switched quickly and accurately, the operation is simple and convenient, and because the micro-electromechanical optical switch device used works in the locked state (that is, switch the channel when the power is turned on, and maintain the current path when the power is turned off), the device is energy-saving.
