The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
Fig. 1 is a block diagram of a mobile terminal 100 according to an embodiment of the present invention. The mobile terminal 100 may be any mobile device having audio acquisition and audio playing functions, such as a mobile phone, a notebook computer, a PDA (Personal Digital Assistant), and the like.
The mobile terminal 100 includes a device failure detection apparatus 200, a memory 110, a processor 120, a sounding device 130, and an audio collecting device 140.
The memory 110, the processor 120, the sound generator 130 and the audio collector 140 are electrically connected directly or indirectly to realize data transmission or interaction. For example, the components may be electrically connected to each other via one or more communication buses or signal lines. The device failure detection apparatus 200 includes at least one software functional module that may be stored in the memory 110 in the form of software (software) or firmware (firmware) or solidified in an Operating System (OS) of the mobile terminal 100. The processor 120 is used for executing executable modules stored in the memory 110, such as software functional modules and computer programs included in the device failure detection apparatus 200.
The Memory 110 may be, but is not limited to, a Random Access Memory (RAM), a Read Only Memory (ROM), a Programmable Read-Only Memory (PROM), an Erasable Read-Only Memory (EPROM), an electrically Erasable Read-Only Memory (EEPROM), and the like.
The processor 120 may be an integrated circuit chip having signal processing capabilities. The processor may be a general-purpose processor, including a Central Processing Unit (CPU), a Network Processor (NP), and the like; but may also be a Digital Signal Processor (DSP)), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA) or other programmable logic device, discrete gate or transistor logic device, discrete hardware components. The various methods, steps and logic blocks disclosed in the embodiments of the present invention may be implemented or performed. A general purpose processor may be a microprocessor or the processor may be any conventional processor or the like.
The sound generating device 130 may be any device capable of generating sound, such as a speaker, a loudspeaker, etc. The audio acquisition device 140 may be a microphone.
In this embodiment, the sound generating device 130 and the audio capturing device 140 are electrically connected to the processor 120.
The inventor researches and finds that the user often quits the mobile terminal 100 because the call volume or the play volume of the mobile terminal 100 is small, but in practice, most of the mobile terminals 100 have small volume because the hole corresponding to the sound generating device 130 and/or the hole corresponding to the audio collecting device 140 are blocked by dust and the like. Only the blocked dust and other substances need to be cleaned, so that the volume of the mobile terminal 100 can be recovered to be normal. However, when the user actually uses the audio device 130 or the audio capturing device 140, the user experience is poor, and for manufacturers, the failure rate is high, which causes unnecessary loss.
Therefore, the inventor proposes a device failure detection method and apparatus, which can detect whether the sound generation device 130 and the audio acquisition device 140 have failed during the use of the mobile terminal 100, so as to provide a basis for measures that may be taken later (e.g., outputting a prompt message, etc.).
Fig. 2 is a schematic flow chart of a device failure detection method according to an embodiment of the present invention, where the device failure detection method is applied to the mobile terminal 100 shown in fig. 1. The specific process and steps shown in FIG. 1 are described in detail below.
Step S110, superimposing a test audio signal with a preset intensity in the to-be-output voice signal to obtain a first voice signal, and playing the first voice signal through the sound generating device 130, where the test audio signal includes preset identification information.
Wherein the preset identification information may be a preset fixed sequence code. And when a certain audio signal comprises the preset identification information, the audio signal is represented as a test audio signal. The preset strength is a predetermined strength of the test audio signal, and generally, the same type of mobile terminal 100 may perform a test using the test audio signal with the same preset strength.
The first voice signal is a voice signal obtained by superimposing the test audio signal on the voice signal to be output of the mobile terminal 100, that is, the first voice signal is a voice signal including the test audio signal. Since the test audio signal includes the preset identification information, the first voice signal also includes the preset identification information.
Step S120, the audio collecting device 140 collects the first voice signal played by the sound generating device 130, so as to obtain a second voice signal.
The second voice signal refers to the first voice signal acquired by the audio acquisition device 140, and correspondingly, the second voice signal also includes the preset identification information. The strength of the second speech signal will typically be lower than the strength of the first speech signal due to attenuation during signal transmission.
Step S130, analyzing the second voice signal, and determining whether the second voice signal has the identification information.
During normal use, the user may control the sound generating device 130 to play a corresponding voice signal, and thus, the sound generating device 130 may play other voice signals in addition to the voice signal (i.e., the first voice signal) including the test audio signal. Therefore, after the audio acquisition device 140 acquires the first voice signal played by the sound generation device 130 to obtain a second voice signal, the second voice signal needs to be detected to determine whether the second voice signal includes a signal for testing, and if so, further detection is needed.
Step S140, when the second voice signal has the identification information, comparing the strength of the second voice signal with a preset signal strength to detect whether the sound generating device 130 and the audio collecting device 140 are faulty.
Wherein the preset signal strength may be determined from the test audio signal. In detail, the determination may be made according to the strength of the test audio signal, that is, the preset strength.
For example, assuming that a large number of sound generating devices 130 and audio collecting devices 140 of the mobile terminal X are tested, the test result shows that if the sound generating devices 130 of the mobile terminal X play a test audio signal with a signal intensity a, and the lowest intensity of the test audio signal collected by the audio collecting devices 140 of the mobile terminal X is b, b may be taken as the preset signal intensity.
If the sound generating device 130 of the mobile terminal X plays the test audio signal with the signal intensity a, the average intensity of the test audio signal collected by the audio collecting device 140 of the mobile terminal X is c, and c may also be used as the preset signal intensity.
In this embodiment, the mobile terminal 100 may only include one audio capturing device 140, in which case, in step S140, the step of comparing the strength of the second voice signal with a preset signal strength to detect whether the sound generating device 130 and the audio capturing device 140 are faulty may be implemented by the following sub-steps:
and judging whether the intensity of the second voice signal reaches the preset signal intensity, and if not, determining that at least one of the sound production device 130 and the audio acquisition device 140 has a fault.
That is, when the mobile terminal 100 includes one audio capturing device 140, the device failure detection method provided in the embodiment of the present invention can determine whether the sound generating device 130 and the audio capturing device 140 are failed as a whole, so as to provide a basis for measures that may be taken later.
Optionally, in this embodiment, the mobile terminal 100 may include two audio capturing devices 140, namely a first audio capturing device and a second audio capturing device.
In this case, in the step S140, the step of comparing the strength of the second voice signal with a preset signal strength to detect whether the sound generating device 130 and the audio collecting device 140 are faulty may be implemented by the following sub-steps:
judging whether a second voice signal acquired by the first audio acquisition device reaches the preset signal intensity or not;
judging whether a second voice signal acquired by the second audio acquisition device reaches the preset signal intensity or not;
when the second voice signals acquired by the first audio acquisition device and the second audio acquisition device do not reach the preset signal intensity, determining that the sounding device 130 has a fault;
when the second voice signal collected by the first audio collection device does not reach the preset signal intensity and the second voice signal collected by the second audio collection device reaches the preset signal intensity, determining that the first audio collection device fails;
and when the second voice signal collected by the second audio collection device does not reach the preset signal intensity and the second voice signal collected by the first audio collection device reaches the preset signal intensity, determining that the second audio collection device breaks down.
The inventor has found that, in practical applications, when the mobile terminal 100 includes two or more audio capture devices 140, the two or more audio capture devices 140 are usually disposed at different positions of the mobile terminal 100, and the corresponding holes of the audio capture devices 140 face different directions. Taking the example that the mobile terminal 100 includes two audio capturing devices 140, typically, one of the two audio capturing devices 140 is disposed on the top of the mobile terminal 100, and the other is disposed on the back of the mobile terminal 100.
Therefore, the holes corresponding to the two audio acquisition devices 140 are less likely to be blocked by dust or the like. Moreover, when the device fault detection method and apparatus provided in this embodiment are used, the plugging of the hole corresponding to any one of the audio capture devices 140 is detected, and therefore, it is necessary to keep the plugging of the hole corresponding to one of the audio capture devices 140 until the plugging of the hole corresponding to another one of the audio capture devices 140 is performed, and finally, a state in which the holes corresponding to two audio capture devices 140 are plugged is achieved, which is less likely.
Based on the above analysis, the inventor designs that when neither of the second voice signals collected by the first audio collecting device and the second audio collecting device reaches the preset signal strength, it is determined that the sound generating device 130 is out of order. And when the intensity of the second voice signal acquired by only one of the first audio acquisition device and the second audio acquisition device does not reach the preset signal intensity, determining that the device has a fault. Thus, the fault detection of the sound generating device 130 and the audio collecting device 140 can be simultaneously realized.
Alternatively, when the mobile terminal 100 includes a plurality of audio capture devices 140, it may be implemented in a similar manner. In detail, in this case, in the step S140, the step of comparing the strength of the second voice signal with a preset signal strength to detect whether the sound generating device 130 and the audio collecting device 140 are faulty may be implemented by the following sub-steps:
counting the number of the audio acquisition devices 140 with the intensity of the second voice signal acquired in the mobile terminal 100 being smaller than the preset signal intensity, determining that the sound generation device 130 fails if the number of the audio acquisition devices 140 included in the mobile terminal 100 is equal to the number of the audio acquisition devices 140 included in the mobile terminal 100, otherwise determining that the audio acquisition device 140 with the intensity of the second voice signal acquired being smaller than the preset signal intensity fails.
Optionally, in this embodiment, the frequency of the test audio signal may be greater than 20KHZ, so that the test audio signal played by the sound generating device 130 cannot be heard by human ears, and thus the fault detection may be performed without disturbing the user, thereby improving the user experience.
Optionally, the method may further comprise the steps of:
when the fault of any one of the sounding device 130 and the audio collecting device 140 is detected, corresponding prompt information is output.
For example, when a problem is detected in the sound generating device 130, a prompt message such as "please check whether the hole of the sound generating device 130 is blocked" or "please clean up dust in the hole of the sound generating device 130" may be output. For another example, in the case of including the first audio capturing device and the second audio capturing device, if it is detected that the first audio capturing device fails, a prompt message "please clean the hole of the first audio capturing device" may be output; if the second audio acquisition device is detected to be out of order, prompt information of 'please clean the second audio acquisition device hole' can be output; if the sounding device is detected to be out of order, prompt information of 'please clean the sounding device hole' can be output.
Thus, the user can clean the mobile terminal in time to recover the volume of the mobile terminal 100, thereby avoiding the situation that the mobile terminal is taken off due to the small volume caused by the problems of dust blockage and the like.
In addition, in practical applications, the reason that the volume of the mobile terminal 100 is small may be the reason of the device itself, in addition to the reason of dust blockage, and therefore, the detected fault information may be fed back to the corresponding server for the manufacturer to analyze.
Thus, the device failure detection method may further include the steps of:
when any one of the sounding device 130 and the audio acquisition device 140 is detected to be out of order, recording corresponding failure information;
and sending the recorded fault information to the server while the mobile terminal 100 feeds back system fault information to the server.
The server refers to a server of a manufacturer of the mobile terminal 100, and the mobile terminal 100 may communicate with the server.
The inventor finds that a link for a user to feed back system fault information is usually provided in the mobile terminal 100, and the user can feed back the system fault information to the server by clicking the link.
In this embodiment, while the mobile terminal 100 feeds back system fault information to the server, the currently recorded fault information may be sent to the server. Therefore, the fault information collected without the operation of the user can be fed back to the server, so that the manufacturer can perform corresponding analysis according to the fault information.
Alternatively, the device failure detection method provided in the present embodiment may have different execution conditions.
For example, a test key may be provided in the mobile terminal 100, and a tester of a user or a manufacturer (including a manufacturer selling or manufacturing the mobile terminal 100) may trigger the mobile terminal 100 to perform step S110 through the test key. The test key may be a virtual key or a physical key, which is not limited in this embodiment.
For another example, the device failure detection method provided in this embodiment may be performed every preset time interval to detect the sound-producing device 130 and the audio capture device 140. In this case, there may be a case where there is no voice signal to be output in the mobile terminal 100, and at this time, the amplitude of the voice signal to be output may be defaulted to 0.
For another example, the device failure detection method provided by the present embodiment may be triggered and executed when the user answers a phone call or plays music. In this case, as an embodiment, before step S110, the method may further include the steps of:
detecting whether the mobile terminal 100 performs voice communication with an external device;
and when the mobile terminal 100 is detected to perform voice communication with an external device, the step of superimposing a test audio signal with a preset intensity on the voice signal to be output is performed.
The external device may be any device having a voice communication function. The voice communication includes voice communication realized by telephone communication, social software and the like.
As another embodiment, before step S110, the method may further include the steps of:
detecting whether the mobile terminal 100 receives an audio file playing instruction;
and when the mobile terminal 100 receives an audio file playing instruction, executing the step of superimposing the test audio signal with the preset intensity in the voice signal to be output.
The audio file playing instruction may be an instruction to play music or an instruction to play video, which is not limited in this embodiment.

Alternatively, the mobile terminal 100 may include a first audio capturing device and a second audio capturing device. The analysis module 230 may compare the intensity of the second voice signal with a preset signal intensity to detect whether the sound generating device 130 and the audio collecting device 140 are malfunctioning by:
judging whether a second voice signal acquired by the first audio acquisition device reaches the preset signal intensity or not;
judging whether a second voice signal acquired by the second audio acquisition device reaches the preset signal intensity or not;
when the second voice signals acquired by the first audio acquisition device and the second audio acquisition device do not reach the preset signal intensity, determining that the sounding device 130 has a fault;
when the second voice signal collected by the first audio collection device does not reach the preset signal intensity and the second voice signal collected by the second audio collection device reaches the preset signal intensity, determining that the first audio collection device fails;
and when the second voice signal collected by the second audio collection device does not reach the preset signal intensity and the second voice signal collected by the first audio collection device reaches the preset signal intensity, determining that the second audio collection device breaks down.
