Description

Speaker fault processing method and device

Technical field

The present application relates to, but is not limited to, the field of audio equipment, and in particular, to a speaker fault processing method and apparatus.

Background technique

Many mobile terminals are currently designed with multiple speakers. Taking two speakers as an example, in order to ensure the audible effect during the playing of music, the preset software will force the PCM (Pulse Code Modulation) audio data to be right and left according to the left and right fixed positions of the speaker. The channel is isolated from left and right, and then output separately to achieve stereo effects. For example, the speaker at the top of the screen represents the left channel, and the speaker at the bottom of the screen represents the right channel, then the upper speaker outputs the audio data of the left channel, and the lower speaker outputs the audio data of the right channel.

In addition, during the voice call, it is up to the manufacturer to use the speaker at the top of the screen or the speaker at the bottom of the screen. Because of the characteristics of the voice call mono, it is output in mono.

If a single speaker in two speakers is damaged due to a special cause (such as poor contact or burnout), a single channel will be silent, then the sound will be incomplete when playing video or audio, such as only the left channel or Only the right channel, this will bring great inconvenience to the user. In another case, if one of the speakers is used in the voice call and the speaker is damaged, the user will not be able to make a normal hands-free or hand-held call.

The structure of the mobile phone of this embodiment is as shown in FIG. 3. The mobile phone includes two speakers at the top and the bottom. The top speaker makes a handset during a voice call, and plays left channel PCM data while playing music; the bottom speaker plays when playing music. PCM data for the right channel.

When the mobile phone of this embodiment plays music, the process of processing the fault is as shown in FIG. 4, and includes the following steps:

S401. Use the app to play music or video. In this embodiment, the mobile phone uses a built-in music player to play music or a video player to play video, and also supports a third-party playing application. The multimedia processor in the mobile phone is responsible for decoding the audio or video file in the multimedia format into general PCM data; the data sending unit is responsible for converting the decoded PCM data into a DAC (Digital to Analog Convert) into a sound. signal. (1) For the case of a single speaker, the synthesis and switching audio output device is responsible for synthesizing the decoded stereo PCM into a mono PCM output to a single speaker; (2) for the case of two speakers, the synthesis and switching audio output device is responsible for The decoded stereo PCM left and right channel data are isolated and output to two separate speakers. This embodiment is the case of the (2)th case.

S402. Detect whether the speaker is faulty. In this embodiment, the fault detecting unit detects whether the speaker refers to a fault such as an overcurrent, a damage, an open circuit, or a short circuit. The fault detection unit contains two MICs (microphones), a top MIC and a bottom MIC. At present, the two MICs basically become the standard hardware design of mobile terminals. The top MIC is responsible for collecting the audio output sound data of the top speaker, and the bottom MIC is responsible for collecting the sound data of the bottom speaker. When the music player is started to play music or the video player plays the video, the two MICs are in a working state at regular time intervals, for example, 1 second, and the sound signals of the two speakers are collected. If the audio data amplitude signal collected by the top MIC is low or not at all, the top speaker is damaged. If the bottom MIC captures the audio If the data amplitude signal is low or not at all, the bottom speaker is damaged. Due to the location of the MIC and the phase principle of the sound transmission, it is entirely feasible to collect different speaker sound data from the top MIC and the bottom MIC, respectively.

S403. If the fault detecting unit detects that a single speaker has failed, converting the played audio data into mono audio data (combining the output stereo PCM data into mono data) and sending it to a good single speaker for playback. ;

S404. If it is detected that no fault occurs in the two speakers, the normally played PCM data is sent to the left and right speakers according to the left and right channel isolation to achieve a stereo effect;

S405. If it is detected that both speakers are faulty, the user is prompted to "the machine speaker is damaged".
