Specifically, the scheme that whether is blocked of sound outlet of loudspeaker mainly point two types are determined in the embodiment of the present invention, first kind scheme is the difference size between the waveform played according to the waveform and expectation of loudspeaker actual play, determines whether the sound outlet of loudspeaker is blocked.Such method does not need to do the extension of hardware aspect, using flexible.Whether the second class scheme is that sensor is arranged inside or around the sound chamber of loudspeaker, be blocked by the sound outlet of sensor measurement loudspeaker.Wherein, sensor may include at least one of lower sensor: sound pressure sensor, baroceptor, range sensor, ambient light sensor or pressure sensor.Sensor in the embodiment of the present invention also may include other kinds of sensor, and this is not limited by the present invention.It is hereinafter described in this step and determines loudspeaker sound exports the specific method whether being blocked.
A. determine whether speaker outlet is blocked according to the broadcasting waveform of audio.
Optionally, as an example, it determines whether the sound outlet of loudspeaker is blocked in 402 parts, can be, in the case where 401 parts determine that the currently used loudspeaker of mobile terminal plays the audio, the expectation for obtaining the audio plays waveform；Obtain the actual play waveform of the audio；Waveform and the actual play waveform are played according to the expectation, determines whether the sound outlet of the loudspeaker is blocked.Wherein, the embodiment of the present invention determines that mobile terminal is currently used only loudspeaker and plays the audio suitable for 401 parts, or determines the case where currently used loudspeaker of mobile terminal and earpiece play the audio simultaneously.
In the case where the sound openings of loudspeaker are blocked, the amplitude of the actual play waveform of audio will be less than the amplitude of expectation broadcasting waveform.The amplitude that waveform can be played by expectation is greater than the waveforms amplitude of actual play, and then determines that the sound outlet of loudspeaker is blocked.Alternatively, by determining that expectation plays waveform Amplitude is less than or equal to the amplitude of actual play waveform, and then determines that the sound outlet of loudspeaker is not blocked.Optionally, above-mentioned amplitude can be average amplitude.Alternatively, " Occlusion effect " can be generated in the case where the sound outlet of loudspeaker is blocked, the sound energy value of the low frequency region of the audio played is caused to improve, " Occlusion effect " is more serious, and what the sound energy value of low frequency region was promoted is just more obvious.The low frequency region energy of expectation broadcasting waveform can be greater than by determining the low frequency region energy of actual play waveform, and then determine that the sound outlet of loudspeaker is blocked, or the low frequency region energy by determining actual play waveform is less than or equal to expectation and plays the low frequency range energy of waveform, and then determines that the sound outlet of loudspeaker is not blocked.
Optionally, the expectation of the above-mentioned acquisition audio plays waveform, comprising: obtains the audio from the audio buffer of the mobile terminal and plays waveform in the expectation of target time section；The actual play waveform of the above-mentioned acquisition audio, comprising: the audio is obtained in the actual play waveform of the target time section by the microphone in the mobile terminal.
For example, obtain audio expectation play waveform, can be mobile terminal processor is obtained from the audio buffer of mobile terminal audio real-time waveform data copy, and combine current system sound volume rank, generate expectation broadcasting waveform Wave data.The actual play waveform of audio is obtained, the processor that can be mobile terminal picks up current ambient sound by microphone, and handles the ambient sound of pickup, to obtain the Wave data of the actual play waveform of audio.Above two Wave data is subjected to time synchronization, intercepts the Wave data of target time section respectively.
Such as, the amplitude of the expectation broadcasting waveform of above-mentioned acquisition and the Wave data of actual play waveform can be compared, if the amplitude of actual play waveform is less than the amplitude that expectation plays waveform, it can then determine that the sound outlet of the loudspeaker is blocked, if the amplitude of actual play waveform is more than or equal to the amplitude that expectation plays waveform, it can determine that the sound outlet of the loudspeaker is not blocked.
Optionally, above-mentioned that waveform and the actual play waveform are played according to the expectation, determine whether the sound outlet of the loudspeaker is blocked, comprising: determine that the expectation plays the low frequency region energy of waveform；Determine the low frequency region energy of the actual play waveform；The low frequency region energy of waveform and the low frequency region energy of the actual play waveform are played according to the expectation, determines whether the outlet of the loudspeaker is blocked.
For example, above-mentioned determining expectation plays the low frequency region energy of waveform, it can be and the Wave data that the expectation of above-mentioned acquisition plays waveform and actual play waveform is respectively converted into frequency spectrum data.And the low frequency region energy of the frequency spectrum data of two kinds of waveforms is calculated separately according to frequency spectrum data.
B. determine whether the sound outlet of loudspeaker is blocked by sensor.
Optionally, as an example, determine whether the sound outlet of loudspeaker is blocked in 402 parts, It may include: to pass through the atmospheric pressure value (or sound pressure level) that baroceptor (or sound pressure sensor) obtains the intracavitary portion of sound of the loudspeaker in the case where 401 parts determine that loudspeaker broadcasting audio is being currently used in mobile terminal；In the case where the atmospheric pressure value (or sound pressure level) is greater than air pressure threshold value (or acoustic pressure threshold value), determine that the sound outlet of the loudspeaker is blocked；In the case where the atmospheric pressure value (or sound pressure level) is less than or equal to the air pressure threshold value (or acoustic pressure threshold value), determine that the sound outlet of the loudspeaker is not blocked.Wherein, the present invention implements to determine that mobile terminal is currently used only loudspeaker and plays audio suitable for 401 parts, or determines the case where currently used loudspeaker of mobile terminal and earpiece play audio jointly.
Wherein, the baroceptor or the sound pressure sensor can be located at the intracavitary portion of sound of the loudspeaker.In the case where the sound outlet of loudspeaker is blocked, the acoustic pressure in the intracavitary portion of the sound of loudspeaker or air pressure will increase.So whether predetermined threshold can be greater than according to atmospheric pressure value or sound pressure level, determine whether the sound outlet of loudspeaker is blocked.Above-mentioned atmospheric pressure value (or sound pressure level) can be the average value of atmospheric pressure value (or sound pressure level).
Optionally, as an example, whether the sound outlet of above-mentioned determining loudspeaker is blocked, comprising: determines the target range between the object and the sound outlet of the loudspeaker by range sensor；In the case where the target range is less than distance threshold, determine that the sound outlet of the loudspeaker is blocked；In the case where the target is specifically greater than distance threshold, determine that the sound outlet of the loudspeaker is not blocked.
