Embodiment one

Referring to FIG. 1 , it shows a flow chart of steps of a method for detecting the state of a sound emitting device according to Embodiment 1 of the present invention.

The method for detecting the state of a sounding device provided in an embodiment of the present invention includes the following steps:

Step 101: Record and play the ultrasonic audio signal to generate a first recording file.

In the embodiment of the present invention, when detecting the state of the sounding device, the ultrasonic audio signal higher than 20kHz can be played through the sounding device, specifically, the ultrasonic audio signal of 23kHz, 24kHz or higher frequency can be played, and the played ultrasonic audio can be recorded. signal, determine the recorded audio file as the first recording file, and store the first recording file in the mobile terminal.

It should be noted that the sound-generating device may be a sound-generating device such as an earpiece or a speaker, and the specific type of the sound-generating device is not limited in the embodiment of the present invention.

Step 102: Obtain a first ultrasonic segment with a preset duration in the first recording file.

It should be noted that those skilled in the art can select the preset duration according to the actual situation. The preset duration can be 100ms, 200ms, 300ms, etc. The embodiment of the present invention does not specifically limit the preset duration.

Obtain the ultrasonic waves in the first recording file, and intercept the ultrasonic waves according to the preset time length to obtain the first ultrasonic segment, wherein the first ultrasonic segment corresponds to a peak, a trough, and a signal value corresponding to each moment.

Step 103: Calculate the energy value of the first ultrasonic segment.

Those skilled in the art can calculate the energy value of the first ultrasonic segment by any appropriate method; for example, when calculating the energy value of the ultrasonic segment, signal sampling can be performed from the ultrasonic segment, and the ultrasonic wave can be obtained by calculating the signal strength of each sampled signal. segment energy value. This is not specifically limited in the embodiments of the present invention.

Step 104: Compare the energy value of the first ultrasonic segment with a preset energy value, and output a state detection result of the sounding device according to the comparison result.

The energy value corresponding to the first ultrasonic segment is calculated according to the signal strength in the first ultrasonic segment, and the calculated energy value of the first ultrasonic segment is compared with a preset energy value calculated by using a normal sounding device. When the energy value of the first ultrasonic segment is less than the preset energy value, it indicates that there are foreign objects or dust in the sound outlet of the sounding device; when the energy value of the first ultrasonic segment is consistent with the preset energy value, it indicates that the sounding device is normal and there is no The problem of dust or foreign matter filling the sound outlet.

By judging the difference between the energy value of the first ultrasonic segment and the preset energy value, it is possible to judge the blocking of the sound outlet of the sound emitting device.

The method for detecting the state of the sounding device provided by the embodiment of the present invention compares the energy of the first ultrasonic segment in the first recording file obtained by recording the played ultrasonic audio signal with the preset energy value to detect the sounding device of the mobile terminal. Whether it is abnormal, because the ultrasonic wave is a high-frequency wave, if it is blocked in the transmission process, it will cause reflection. The energy value of the ultrasonic wave of the abnormal sounding device will be weaker than the normal ultrasonic energy value. Therefore, by comparing the energy value of the first ultrasonic segment. Weak, it is possible to determine the state of the sound emitting device of the mobile terminal, and only when a small amount of foreign matter or dust enters the sound outlet, the state of the sound emitting device can be detected in real time, thereby improving the user's listening experience.

The method for detecting the state of a sounding device provided in an embodiment of the present invention includes the following steps:

Step 201: Simultaneously play the audio file and the ultrasonic audio signal, and record to generate a recording file.

In the embodiment of the present invention, when the mobile terminal plays sound or music, the ultrasonic audio signal is played at the same time. Since the ultrasonic wave is a sound wave beyond the human audible range of 20-20kHz, and the frequency is above 20kHz, it does not affect the audio frequency during use. The user's sense of hearing, so the ultrasonic audio signal can be played while playing music, so as to detect the state of the sound-emitting device during use. Moreover, the ultrasonic wave interacts with the sound-generating device, so that the detection of the sound-generating device can be completed without damaging the sound-generating device.

Step 202: Filter the audio files in the recorded files to generate a first recorded file.

Wherein only ultrasonic audio signals exist in the first recording file.

Due to the presence of audio files or audio signals and ultrasonic signals in the recorded files, high-pass filtering is used to filter low-frequency signals, that is, audio files and audio signals. In the actual process, there may be noise in the recorded files due to the noisy recording environment. Noise can be filtered out by high-pass filtering, so that only ultrasonic audio signals exist in the first recording file.

Step 203: Obtain the first ultrasonic segment with a preset duration in the first recording file.

Acquiring the ultrasound in the first recording file, intercepting the ultrasound according to a preset time length, and intercepting a certain segment in the first recording file for subsequent algorithm calculation on the ultrasound segment.

It should be noted that those skilled in the art can select the preset duration according to the actual situation. The preset duration can be 100ms, 200ms, 300ms, etc. The embodiment of the present invention does not specifically limit the preset duration.

Step 204: Obtain the signal strength corresponding to each sampled signal in the first ultrasonic band.

The first ultrasonic segment is discretized into a plurality of sampling signals according to the sampling number, and signal strengths corresponding to these sampling signals are acquired.

The higher the sampling frequency and the shorter the sampling interval, the more sample data the computer can obtain per unit time, and the more accurate the representation of the signal waveform. There is a certain relationship between the sampling frequency and the original signal frequency. According to the Nyquist theory, only when the sampling frequency is higher than twice the highest frequency of the original signal can the signal represented by the digital signal be restored to the original signal. Therefore, an optimal The adopting method is to sample the first ultrasonic band signal according to twice the frequency of the ultrasonic signal.

Step 205: Calculate the sum of the squares of the signal strengths to obtain the energy value of the first ultrasonic segment.

By formula: Calculate the energy value of the first ultrasonic segment, where n is the number of samples, and x(n) is each sampled signal.

Step 206: Calculate the difference between the energy value of the first ultrasonic segment and a preset energy value.

Among them, the preset energy value is generated in the following way: using a mobile terminal with a normal sounding device, recording and playing the ultrasonic audio signal to generate a second recording file; obtaining the second ultrasonic segment with a preset duration in the second recording file; calculating the second The energy value of the ultrasonic segment, determining the energy value of the second ultrasonic segment as the preset energy value.

Calculate the difference between the energy value of the first ultrasonic segment and the preset energy value, and the difference can indicate the blocking degree of the sound-generating device.

Step 207: Compare the difference with a difference threshold.

Step 208: When the difference is less than or equal to the difference threshold, output first prompt information for indicating that the state of the sound generating device is normal.

Step 209: When the difference is greater than the difference threshold, output second prompt information for indicating that the state of the sound generating device is abnormal.

Those skilled in the art can set the difference threshold according to the actual situation, for example, the difference threshold can be set to 10, 20, 30, etc. The embodiment of the present invention does not specifically limit the setting of the difference threshold.

When the difference threshold is 20, and the calculated difference is 10, if 10 is less than 20, it indicates that the sound-emitting device is in normal state, and at the same time output a prompt message prompting that the state of the sound-emitting device is normal, which can be vibration, flashing text and pop-up Output the first prompt message in the form of a prompt box.

When the difference threshold is 20, when the calculated difference is 30, 30 is greater than 20, indicating that the state of the sounding device is abnormal; when the calculated difference is 40, and 40 is greater than 20, the state of the sounding device with a difference of 40 is abnormal The sound-generating device whose degree is higher than the difference of 30 can send out different second prompt information according to the level of the abnormality, so as to remind the user of the state of the sound-generating device.

The sound-emitting device state detection method provided by the embodiment of the present invention generates a recording file by recording the played audio file and the ultrasonic audio signal, and filters the recording file to obtain the first recording file.
