Embodiment 1

[0023] figure 1 It is an implementation flowchart of the audio signal output method provided by the embodiment of the present invention, and is described in detail as follows:

[0024] In step S101, detect whether the intelligent mobile terminal accesses the audio data line;

[0025] Wherein, the optical fiber audio interface is installed in the intelligent mobile terminal.

[0026] Wherein, the optical fiber audio interface and the analog audio interface are separated or integrated together.

[0027] In step S102, when the smart mobile terminal accesses the audio data line, it is judged whether the audio data line accessed is an optical fiber data line;

[0028] In step S103, when the connected audio data line is an optical fiber data line, digital audio signals are provided to the external audio system through the optical fiber audio interface and the optical fiber data line on the smart mobile terminal.

[0029] Wherein, the optical fiber data cable is connected to the o...

Embodiment 2

[0041] The embodiment of the present invention describes the implementation process of judging whether the audio data line accessed is an optical fiber data line, and the details are as follows:

[0042] When the smart mobile terminal accesses the audio data line, it judges whether the audio data line accessed is an optical fiber data line according to the pre-configured audio data line type discrimination thread.

Embodiment 3

[0044] The embodiment of the present invention describes the implementation process of configuring the audio data line type discrimination thread, which is described in detail as follows:

[0045] When the smart mobile terminal accesses the audio data line, before judging whether the audio data line connected is an optical fiber data line, the audio signal output method also includes:

[0046] Configure the audio data line type identification thread.

Abstract

The invention is applicable to the field of intelligent mobile terminals, and provides an audio signal output method and device. The audio signal output method comprises the following steps: detecting whether an intelligent mobile terminal is accessed to an audio data line; when the intelligent mobile terminal is accessed to the audio data line, judging whether the accessed audio data line is an optical fiber data line; and when the accessed audio data line is the optical fiber data line, providing a digital audio signal for an external sound through an optical fiber audio interface on the intelligent mobile terminal and the optical fiber data line. The audio signal output method and device provided by the invention have the following beneficial effects in two aspect: the first aspect is that, the intelligent terminal can provide a better sound source for an enthusiast sound, so that the enthusiast sound can play a better role, and the user experience can be well improved; and the second aspect is that, by automatically distinguishing an optical fiber digital audio interface and a common analog audio interface, different types of audio signals can be accurately outputted and the need of playing music of different qualities can be satisfied.

Description

technical field [0001] The invention belongs to the field of intelligent mobile terminals, and in particular relates to an audio signal output method and device. Background technique [0002] With the advent of the intelligent era of smart mobile terminals, the configuration of smart mobile terminals is becoming more and more powerful, and the functions are becoming more and more complete. The programs suitable for smart mobile terminals are also varied and increasing. Users can download and play their own favorite music. [0003] However, existing smart terminals cannot output digital audio signals, cannot provide better digital audio sources for audiophiles, and are not conducive to improving audio playback effects. The reason is that, in the prior art, smart mobile terminals usually only have a 3.5mm audio interface, so it will not be possible to judge whether the audio data cable connected is an optical fiber data cable, and thus cannot output digital audio signals, and...
