Embodiment 1

[0041] A loudspeaker fault handling method according to the embodiment of the present invention is as follows: figure 1 As shown, the present embodiment is used for a device with multiple speakers. The method first detects whether a speaker fails; Play; and when the speaker fails, a speaker failure prompt is issued to the user. In this embodiment, at least one of the faulty speaker and the non-faulty speaker is:

[0042] (1) When there is only one speaker with a fault and one speaker without a fault, the data of the speaker with a fault is sent to the speaker without a fault for playback.

[0043] (2) When there are multiple faulty speakers and one non-faulty speaker, send the data of all faulty speakers to the non-faulty speaker for playback.

[0044] (3) When there is one loudspeaker that breaks down and there are multiple loudspeakers without trouble, the data of the loudspeaker that breaks down is sent to a certain loudspeaker without trouble to play. specified.

Embodiment 2

[0051] A loudspeaker failure processing device according to an embodiment of the present invention is as follows: figure 2 As shown, this embodiment is used for equipment with multiple speakers, and the device includes a fault detection unit 21, a data transmission unit 22 and a prompt unit 23, wherein the fault detection unit 21 is connected to the data transmission unit 22 and the prompt unit 23 respectively.

[0052] The fault detection unit 21 is used to detect whether the speaker is faulty. The fault detection unit 21 includes a signal collection sub-unit 211 and a fault judgment sub-unit 212 , wherein the signal collection sub-unit 211 and the fault judgment sub-unit 212 are connected. The signal collection subunit 211 is used to collect the sound signal output by the speaker when playing audio through the speaker; in this embodiment, the signal collection subunit 211 is a microphone close to the speaker. The fault judging subunit 212 is used to judge whether the ampli...

Embodiment 3

[0056] In this embodiment, a mobile phone is taken as an example to specifically describe a method for handling a speaker failure. In this embodiment, in addition to necessary communication, display, audio and other subsystems, the mobile phone also uses a dual-speaker design in hardware design. The structure of the mobile phone of the present embodiment is as image 3 As shown, the mobile phone includes two speakers at the top and the bottom. The top speaker is used as an earpiece during a voice call, and plays left channel PCM data when playing music; the bottom speaker plays PCM data with sound when playing music.

[0057] When the mobile phone of this embodiment is playing music, the process of handling the fault is as follows: Figure 4 shown, including the following steps:

[0058] 1. 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 videos, and also supports third-party playba...

Abstract

The invention discloses a loudspeaker fault processing method comprising the following steps: whether loudspeakers malfunction is detected; when a malfunctioning loudspeaker is detected, data of the malfunctioning loudspeaker is sent to a fault-free loudspeaker and played by the same. The invention also discloses a loudspeaker fault processing apparatus. The loudspeaker fault processing method andapparatus can be used for controlling different audio output modes by detecting whether the loudspeakers malfunction in equipment equipped with a plurality of loudspeakers, and a user is enabled to enjoy completeness of basic functions when only one loudspeaker is in a good condition.

Description

technical field [0001] The invention relates to the field of audio equipment, in particular to a method and device for troubleshooting a loudspeaker. Background technique [0002] At present, many mobile terminals are designed with a solution of multiple loudspeakers. Taking the use of two speakers as an example, in the process of playing music, in order to ensure the auditory effect, the preset software at the factory will force the PCM (Pulse Code Modulation, Pulse Code Modulation) audio data to be adjusted according to the left and right fixed positions of the speakers. The left and right channels are isolated, and then output separately to achieve a stereo effect. For example, the speaker above the screen represents the left channel, and the speaker below 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. [0003] In addition, during a voice call,...
