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. Environmental friendly

Embodiment Construction

[0032] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0033] see figure 1 , the figure shows a preferred embodiment of an audio-optical signal path switching device of the present invention. In this embodiment, the two audio-optical signal sources are respectively from the CD player 1 and the computer 2, and the audio-optical signal path switching device 3 can switch the two input audio-optical signals, and directly transmit the output audio-optical signal to a device equipped with The speaker device 4 with the optical fiber interface realizes the non-pluggable audio-optical signal channel switching. The audio and optical signal source may come from equipment such as DVD player, CD player, LCD TV or computer equipped with optical fiber interface, but is not limited thereto.

[0034] see figure 2 and image 3 , as shown in the figure, the audio-optical signal path switching device of the present inventi...

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

technical field [0001] The invention belongs to the technical field of audio signal switching, and in particular relates to a method and device for switching audio and optical signal paths. Background technique [0002] With the rapid development of science and technology, there are more and more types of technological consumer goods, and their functions are constantly updated, playing an increasingly important role in people's daily life, work and entertainment. Taking audio-visual entertainment as an example, it has occupied most of the leisure ways in modern people's life. Corresponding electronic consumer products, such as 3D TV, DVD player, high-definition LCD monitor, notebook computer, tablet, desktop computer, etc., are dazzling. It has been stationed on the best-selling lists of major supermarkets for a long time. Obviously, the increasingly perfect realistic audio output function of this kind of products is indispensable for this. At the same time, in order to cat...
