Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Fig. 1 is a schematic block diagram illustrating an audio output detection apparatus according to an exemplary embodiment, which may be applied to a terminal of a mobile phone or a tablet computer, and the following exemplary embodiment of the disclosure is mainly applied to a case where the apparatus is applied to a mobile phone. As shown in fig. 1, the apparatus includes:

the audio output module 11 is used for outputting audio signals and is arranged at one end of the terminal;

the audio receiving module 12 is configured to receive the audio signal, and is disposed at the same end of the terminal as the audio output module;

in one embodiment, the audio output module and the audio receiving module may be located at the same end of the terminal, so that the audio signal output by the audio output module can be received by the audio receiving module only by propagating for a short distance, thereby reducing the intensity lost in the propagation process, and facilitating the subsequent calculating module to accurately calculate the first difference value accordingly.

A calculating module 13, configured to calculate a first difference between a preset intensity and an intensity of the audio signal;

and the prompting module 14 is configured to generate a prompting message for prompting that the sound outlet of the audio output module is blocked, when the first difference is greater than 0.

In one embodiment, the prompt message may be a text prompt message or an audio prompt message.

In one embodiment, the user may trigger the calculation module to calculate the first difference value by inputting the detection instruction, and the calculation module and the prompt module may stop working when the user does not output the detection instruction.

In one embodiment, the preset intensity may be the measured intensity of the audio signal output by the audio output module when the sound outlet is blocked by a preset percentage (which may be set as required, and may be 10% for example) in advance. In the case that the first difference between the preset intensity and the intensity of the audio signal is greater than 0, it may be determined that the intensity of the audio signal is less than the preset intensity, that is, the percentage of the sound outlet being blocked is greater than the preset percentage. In the daily use process, the sound outlet cannot be kept completely unblocked, and blockage to a certain degree exists more or less, so that the blockage of the sound outlet can be judged under the condition that the blockage percentage of the sound outlet is greater than the preset percentage, the user listening is influenced, and then prompt information is generated.

Fig. 2 is a schematic diagram illustrating a sound outlet according to an exemplary embodiment. Fig. 3 is a schematic diagram illustrating an audio receiving module according to an example embodiment. Fig. 4 is a schematic diagram illustrating another audio receiving module according to an example embodiment.

In one embodiment, taking a mobile phone as an example, the audio output module and the audio receiving module may be located on the top of the mobile phone, for example, the audio output module is an earphone, and the sound outlet 10 of the audio output module may be as shown in fig. 2. In this case, the audio receiving module 12 may be a noise reduction microphone, which may be disposed at an upper rim of the cellular phone as shown in fig. 3, or may be disposed at the top of a rear cover of the cellular phone as shown in fig. 4.

It should be noted that the audio receiving module 12 shown in fig. 3 and 4 is actually a sound inlet of the noise reduction microphone, and in this embodiment, is only used to illustrate the approximate position of the noise reduction microphone.

In one embodiment, taking a mobile phone as an example, the audio output module and the audio receiving module may also be located at the bottom of the mobile phone, for example, the audio output module is a speaker, and then the sound outlet 10 of the audio output module may be as shown in fig. 5. In this case, the audio output module may be a speaker, and the audio receiving module may be a microphone.

In one embodiment, the audio receiving module receives the audio signal output by the audio output module, and compares the intensity of the audio output signal with the preset intensity, so that whether the sound outlet of the audio output module is blocked can be accurately determined according to the comparison result, and then prompt information is generated under the condition of blocking, so that a user can accurately and timely determine that the sound outlet is blocked. On the one hand, the accuracy of determining whether the sound hole is blocked can be improved, and on the other hand, the operation of determining whether the sound hole is blocked can be simplified.

In one embodiment, the third difference may be calculated directly from the preset intensity, the intensity of the audio signal, and the upper and lower limits of the fluctuation range, without calculating the first and second differences and then calculating the third difference.

In one embodiment, since the preset intensity is the measured intensity of the audio signal output by the audio output module under the condition of the preset percentage of the blocked sound outlet, the data measured for a plurality of times generally have a certain difference, that is, the preset intensities are within a fluctuation range, for example, the fluctuation range is 20 db to 25 db, and then the second difference is equal to 5 db. In this case, if the preset intensity for comparison with the intensity of the audio signal is 23 db and the intensity of the audio signal is 21 db, the first difference is equal to 2 db, and the third difference is equal to-3 db, which is less than 0, so that the prompt message is not generated.

When the preset intensity is selected as a large value in the fluctuation range, for example, 23 db, the proportion of the sound outlet blockage does not reach the preset percentage, and the intensity of the audio signal is large, for example, 21 db, then the first difference is 2 db and is greater than 0, and the sound outlet blockage can still be prompted based on the first difference, so that the misjudgment is generated.

However, according to the above-described embodiment, in the case where the first difference is larger than 0, the prompt information is not generated, but the prompt information is generated only in the case where it is determined that the third difference is larger than 0. Therefore, the phenomenon that the sound outlet is blocked by misjudgment can be avoided under the condition that the blockage proportion of the sound outlet does not reach the preset percentage.

FIG. 6 is a schematic block diagram illustrating another audio output detection device in accordance with an exemplary embodiment. As shown in fig. 6, on the basis of the embodiment shown in fig. 1, the apparatus further includes:

a query module 15, configured to query a blockage percentage corresponding to the first difference;

wherein, the prompt module 14 is configured to generate the prompt message according to the blockage percentage.

In one embodiment, since different users have different requirements for the degree of openness of the sound outlet, based on the fixed preset intensity, the correlation between the blocked area and the first difference value may be stored in advance, for example, in the case where the first difference value is-5, the blocked area is 0; under the condition that the first difference value is-4, the blocking area is 2 percent; under the condition that the first difference value is-3, the blocking area is 4 percent; under the condition that the first difference value is-2, the blocking area is 6 percent; under the condition that the first difference value is-1, the blocking area is 8 percent; when the first difference is 0, the blocking area is 10%; when the first difference is 1, the blocking area is 12%; in the case where the first difference is 2, the plugging area is 14%; in the case where the first difference is 3, the plugging area is 16%.

For example, in the case where the first difference is-1, although no prompt message is generated, the user can determine that the blocked area of the sound hole reaches 8%. That is, the present embodiment may display the corresponding blockage percentage for the user according to different first difference values, so that the user may determine whether to clean the sound outlet according to the requirement.

In one embodiment, the two embodiments described above may be combined, that is, the audio output module includes both an earphone and a speaker, and the audio receiving module includes both a noise reduction microphone and a microphone.

Then a first preset intensity may be set for the earpiece and the noise reducing microphone and a second preset intensity may be set for the speaker and the microphone. On one hand, the calculation module calculates a difference value between the first preset intensity and the intensity of the audio signal output by the receiver, and the prompt module generates first prompt information for prompting that the sound outlet of the receiver is blocked under the condition that the difference value is greater than 0. The calculation module calculates a difference value between the second preset intensity and the intensity of the audio signal output by the loudspeaker, and the prompt module generates second prompt information for prompting that the sound outlet of the loudspeaker is blocked under the condition that the difference value is greater than 0.

Therefore, different prompt messages can be generated under the condition that the sound outlet hole of the earphone is blocked or the sound outlet hole of the loudspeaker is blocked, so that a user can accurately determine the blocked sound outlet hole and further process the sound outlet hole.
