Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a flowchart of a method for detecting an audio component, which is applicable to detecting a state of an audio component of a terminal device and determining a location of a bad audio component, and can be performed by a detection apparatus of the audio component according to an embodiment of the present invention. The terminal device may be a mobile phone, a tablet, a computer, etc., and the embodiment of the present invention is described by taking a mobile phone as an example. Illustratively, the audio component of the handset includes M microphones and N speakers, where M, N is a positive integer greater than or equal to 2. As shown in fig. 1, the method specifically includes the following steps:
and step 110, sequentially controlling the N loudspeakers to play sound wave detection signals.
Here, the sound wave detection signal refers to a sound source signal for detecting the state of the audio component. The sound source signal is stored in the handset in the form of "files", such as audio files like music and speech. Specifically, the acoustic detection signal is an electrical signal. When the relevant processor in the mobile phone executes the detection of the audio component, the sound wave detection signal can be sent to the loudspeaker, so that the loudspeaker converts the sound wave detection signal into an analog signal, namely, the sound is emitted in a wave form, and the loudspeaker plays the sound wave detection signal. Specifically, the processor controls the N speakers to work in sequence to play the sound wave detection signal.
And step 120, after the sound wave detection signals are played by each loudspeaker, sequentially acquiring the intensity of the sound wave detection signals received by the M microphones.
Wherein, the intensity of the sound wave detection signal is the loudness of the sound wave received by the microphone. After controlling a certain loudspeaker to play a sound wave detection signal, controlling M microphones to be started one by one, namely, only starting one microphone at a time, and acquiring the loudness of sound waves received by the microphone in the starting state until the loudness of sound waves received by all the microphones corresponding to each loudspeaker is acquired.
And step 130, determining the fault position of the audio component according to the strength of the sound wave detection signal received by the microphone.
Specifically, the standard intensity of the sound wave detection signal played by each speaker received by each microphone may be preset, after the intensity of the sound wave detection signal received by all microphones corresponding to each speaker is obtained, the intensity of the sound wave detection signal received by each microphone is compared with the corresponding standard intensity, and the fault position of the audio component is analyzed and determined by screening data that do not meet the standard intensity. For example, if more than 80% of the intensity data of the sound wave detection signals played by the first speaker received by the M microphones do not meet the corresponding standard intensity, it indicates that the first speaker may have a fault, and similarly, if more than 80% of the intensity data of the sound wave detection signals played by the N speakers received by the first microphone does not meet the corresponding standard intensity, it indicates that the first microphone may have a fault.
It should be noted that the method for analyzing the fault location of the audio component is only an exemplary method provided by the embodiment of the present invention, and the embodiment of the present invention does not limit this.
According to the embodiment of the invention, the N loudspeakers are controlled to play the sound wave detection signals in sequence, after each loudspeaker plays the sound wave detection signal, the intensity of the sound wave detection signal received by the M microphones is obtained in sequence, and the fault position of the audio component is determined according to the intensity of the sound wave detection signal received by the microphone, so that the problem that the up-and-down transmission effect of sound of the audio component is influenced due to long-term use is solved, automatic detection and accurate positioning of a bad audio component are realized, and user experience is improved.
On the basis of the foregoing embodiment, optionally, the method for determining the fault location of the audio component according to the strength of the sound wave detection signal received by the microphone may further include:
after the ith loudspeaker plays the sound wave detection signal, when the intensity of the sound wave detection signals received by the M microphones is not consistent with the preset intensity range, determining that the ith loudspeaker breaks down; after the N loudspeakers play the sound wave detection signals, when the intensity of the sound wave detection signals received by the jth microphone is not consistent with the preset intensity range, determining that the jth microphone has a fault; wherein i is more than or equal to 1 and less than or equal to N, and j is more than or equal to 1 and less than or equal to M; i and j are both positive integers.
The preset intensity range is the range of the standard intensity, and the fault tolerance rate can be improved by presetting the range of the standard intensity, so that the analysis result is more reasonable. For example, taking i-1 and j-1 as an example, if the intensity of the sound wave detection signal received by the M microphones and played by the first speaker exceeds the preset intensity range, it may be determined that the first speaker is faulty; similarly, if the intensities of the sound wave detection signals received by the first microphone and played by the N speakers all exceed the preset intensity range, it may be determined that the first microphone has a fault.
Fig. 2 is a flowchart of another audio component detection method according to an embodiment of the present invention, which is optimized. As shown in fig. 2, optionally, before controlling the N speakers to play the sound wave detection signal in sequence, the method further includes:
The environment feature of the audio component is the external environment state of the mobile phone. The mobile phone is internally integrated with various sensors, can detect the external environment where the mobile phone is located, and sends the detection result to the processor for analysis so as to judge whether the current state is suitable for detecting the audio component. The processor compares the received environmental characteristics with the preset conditions, and if the environmental characteristics meet the preset conditions, the detection of the audio component can be executed. For example, the noise of the environment where the mobile phone is located can be collected through a microphone, and whether the environment noise is small enough to meet the preset condition for executing the detection of the audio component is judged; detecting the placement position and the placement state of the mobile phone through a gravity sensor or a gyroscope and the like so as to judge whether the mobile phone is in a static and stable placement state; whether obstacles exist around the loudspeaker and the microphone is detected through the camera or the photoelectric detector, and the sound transmission is blocked. When the environmental characteristics of the audio component meet the preset conditions, the detection of the audio component is executed, so that the accuracy of the detection result can be improved, and invalid detection is avoided.
With continued reference to fig. 2, optionally, after determining the fault location of the audio component according to the strength of the sound wave detection signal received by the microphone in step 130, the method further includes:
The prompt information is used for prompting that the audio component of the user has the fault and the position of the audio component with the fault, and can prompt the user in a voice or message prompting mode so that the user can know the fault problem of the audio component and timely check and maintain the audio component.
In addition, the indication information may also be prompt information indicating that the user places the mobile phone in an environment meeting the preset condition. It can be understood that the environmental characteristics of the mobile phone are obtained by the internal sensor of the mobile phone, and there may be a case where the judgment result is incorrect. Therefore, when the detection result is that a fault audio component exists, the user can be prompted to place the mobile phone in an environment meeting the preset condition and detect the mobile phone again, so that the situation that the judgment of the detection result is wrong due to the judgment of the environmental characteristics is eliminated. If the audio component is detected again and the fault component still exists, the user can be prompted about the position of the fault audio component. Illustratively, the user can be reminded to clean the dust screen of the audio component with the fault, the audio component can be detected again after the cleaning, and if the audio component is still in the fault, the user is prompted to send the mobile phone to a maintenance point to detect the audio component.
Optionally, the acoustic detection signal is an ultrasonic wave.
Compared with voice or music, the ultrasonic wave is selected as the sound wave detection signal, so that a user cannot perceive that the system is executing the detection of the audio component, and the user experience of using the terminal equipment is not influenced.
Optionally, control N speakers in proper order to play sound wave detection signals, include: and sequentially controlling the N loudspeakers to play sound wave detection signals at preset time intervals.
The audio component is detected at intervals, so that bad experience brought to a user by bad audio components can be effectively prevented. The interval time can be set by itself, which is not limited in the embodiment of the present invention. Specifically, after a preset time interval, whether the environmental characteristics of the mobile phone meet preset conditions or not can be judged, and if yes, the detection of the audio component is executed; if the mobile phone is not satisfied, prompting the user to place the mobile phone in an environment satisfying a preset condition, and then detecting; or delaying for a certain time, detecting the environment of the mobile phone, if the environment of the mobile phone does not meet the preset condition for a long time, sending prompt information to the user, and judging whether to start the detection of the audio component according to the selection of the user.
