As shown in figure 1, the speaker voice giving hole plug detection method includes：
S101, obtains speaker system normal impedance value in normal state.
S102, real-time impedance value of the detection speaker system during sound is played.
Whether S103, block according to real-time impedance value and normal impedance value detection speaker voice giving hole.
It should be appreciated that loudspeaker has polytype, but the principle of groundwork is similar, is that one kind will
Electric signal is converted to the element that voice signal is reset, and knows loudspeaker according to impedance value in the present invention for convenience of description
Go out the principle whether acoustic aperture blocks, below by present it is most popular be dynamic speaker as a example by illustrate.
As shown in Fig. 2 (a), dynamic speaker is made up of vibrating membrane, voice coil loudspeaker voice coil, permanent magnet, support etc., when loudspeaker
After voice coil loudspeaker voice coil is passed through tone currents, alternating magnetic field, permanent magnet is produced also to produce a size and side simultaneously in the presence of electric current
To constant constant magnetic field, because the size and Orientation in the magnetic field produced by voice coil loudspeaker voice coil is constantly changing with the change of tone currents
Become, the interaction in two such magnetic field makes voice coil loudspeaker voice coil make the motion of the sense of current in voice coil loudspeaker voice coil, due to voice coil loudspeaker voice coil and vibrating membrane
It is connected, so as to drive vibrating membrane to produce vibration, the vibrations of air is caused by vibrating membrane and sound is sent.
Thus, the factor such as quality and air of offer sound of loudspeaker is related, wherein, open going out in the top of vibrating membrane
When acoustic aperture is blocked, due to have compressed the space of air vibration and increasing the resistance that vibrating membrane vibrates upwards, drop is equivalent to
Impedance value of the low speaker system when voice service is provided.
In an embodiment of the present invention, the real-time impedance value according to speaker system during sound is played, judges to raise
Sound device goes out whether acoustic aperture is blocked during sound is played.
Specifically, obtain speaker system normal impedance value in normal state, using the normal impedance value as
Judge the whether abnormal basis for estimation of the impedance value of speaker system, wherein, can be specific according to above-mentioned standard impedance value
One scope of impedance value, or impedance value, does not limit herein.
, wherein it is desired to explanation, obtain that the mode of normal impedance value is different and different with application scenarios, example is said
It is bright as follows：
The first example, can in advance obtain and store the speaker system pair of different model according to lot of experimental data
The normal impedance value answered, according to the model of loudspeaker in present terminal equipment, inquires about above-mentioned corresponding relation, obtains speaker system
Normal impedance value in normal state.
Second example, because terminal device is when initially use, goes out acoustic aperture and is in more clean state, so that,
In this example, record now speaker system play sound during impedance value as normal impedance value.
Further, real-time impedance value of the detection speaker system during sound is played.
It should be noted that under different application scenarios, the mode for obtaining above-mentioned real-time impedance value is different, in order to more
Clearly illustrate how to detect real-time impedance value of the speaker system during sound is played, be exemplified below.
The first example, can influence in the theory of input impedance curve at electricity end in hole plug of speaking, and continue with electronic
As a example by formula loudspeaker illustrate, in the operation principle of the dynamic speaker as shown in Fig. 2 (b), permanent magnet, upper conduction magnetic board, under
Magnetic conductive board constitutes a magnetic loop, and a uniform magnetic air gap for very little is formed between upper conduction magnetic board and lower magnetic conductive board pole piece,
When there is electric current to pass through in voice coil loudspeaker voice coil, voice coil loudspeaker voice coil will move up and down, so as to promote vibrating membrane to cause air vibration and send sound.
Wherein, the voice coil loudspeaker voice coil of loudspeaker is a coil by enamel-covered wire coiling, and it not only possesses certain direct current
Resistance, the inductance also with, voice coil loudspeaker voice coil itself is moved in magnetic air gap, the cutting magnetic induction line of force, and like being generator, it can be induced
One induced voltage reverse with audio signal, can weaken voice coil loudspeaker voice coil sound intermediate frequency signal code, so that the impedance in voice coil loudspeaker voice coil increases
Greatly.
However, when going out acoustic aperture and being blocked, vibration vibration of membrane is affected, so that, cause the voice coil loudspeaker voice coil cutting magnetic induction line of force
Motion it is hindered, now, the weakening of voice coil loudspeaker voice coil sound intermediate frequency signal code is reduced, the output of drive circuit in speaker system
Voltage and output current are all changed by generations is corresponding, and thus, the output voltage and output current of drive circuit can be anti-in loudspeaker
Reflect real-time impedance value of the speaker system during sound is played.
Thus, in the present embodiment, output voltage and output electric current measure speaker system according to drive circuit are being broadcast
Real-time impedance value during sound reproduction sound.
Second example, the real-time impedance of loudspeaker influences sound quality of the speaker system during sound is played,
The real-time impedance of different loudspeakers, the influence that the generations such as tone color, the volume of sound are played to speaker system is different, thus,
Speaker system can be gathered and play sound, be analyzed according to the sound, speaker system is stated in broadcasting sound process to obtain
In real-time impedance value.
Further, whether blocked according to real-time impedance value and normal impedance value detection speaker voice giving hole, such as fruit
When impedance value it is larger with the difference of normal impedance value, then it is assumed that the acoustic aperture that goes out of loudspeaker is blocked, if real-time impedance value with
The difference of normal impedance value is smaller, then it is assumed that the acoustic aperture that goes out of loudspeaker is not blocked.
It should be noted that under different application scenarios, real-time impedance and normal impedance can be judged using various ways
Whether the difference of value is larger.
As a kind of possible implementation, the difference that normal impedance value subtracts real-time impedance value is calculated, with according to the difference
What value judged loudspeaker goes out whether acoustic aperture is blocked, if difference is larger, then it is assumed that this goes out acoustic aperture and is blocked, if difference compared with
It is small, then it is assumed that this goes out acoustic aperture and is not blocked.
Certainly, in this example, if in actual applications, loudspeaker system may be caused due to some other
The real-time impedance value of system is undergone mutation, but is now gone out acoustic aperture and do not blocked, thus, in order to avoid only according to the big of difference
It is small to judge the whether blocked error brought of acoustic aperture, the difference for obtaining can also be determined whether, to ensure what is judged
Accuracy.
Thus, in this example, after the difference for obtaining real-time impedance value, the ratio of calculating difference and normal impedance value,
And compare the size of ratio and predetermined threshold value, so that, if compare knowing that ratio is more than predetermined threshold value, it is determined that speaker voice giving hole
Block, if compare knowing that ratio is less than or equal to predetermined threshold value, it is determined that speaker voice giving hole does not block.
Wherein, above-mentioned predetermined threshold value is demarcated according to lot of experimental data, can be used to accurately define speaking for loudspeaker
Whether hole blocks.
In sum, the speaker voice giving hole plug detection method of the embodiment of the present invention, obtains speaker system normal
Normal impedance value under state, and real-time impedance value of the speaker system during sound is played is detected, so that, according to real-time
Whether impedance value and normal impedance value detection speaker voice giving hole block.Thus, the resistance value detection according to speaker system is raised
Sound device goes out whether acoustic aperture blocks, and understands the stopping state that acoustic aperture in time in order to user and makes corresponding treatment, it is ensured that
Speaker system can normally provide voice service quality.
Based on above example, it should be appreciated that in actual applications, the blocking for going out acoustic aperture is likely due to user
The temporary transient blocking that causes of finger, such as, user plays out music, plays video or plays game in using terminal equipment
When, may due to needing, both hands are horizontal to hold terminal device, cause the acoustic aperture that of aperture very little to be blocked by finger, it is also possible to be ash
Blocked caused by dirt or fluid accumulation, thus, in order to be easy to user to take appropriate measures, fast quick-recovery loudspeaker system
The quality of the voice service of system, it is thus necessary to determine that the concrete reason of hole plug of speaking.

The real-time impedance value during sound is played, if now still determining speaker voice giving hole plug, shows to cause acoustic aperture to be blocked up
The reason for plug is not that user's finger is blocked, it may be possible to blocked caused by dust or liquid on dust-proof screen cloth, so as to point out
The dust-proof mesh clogging in user's speaker voice giving hole, clears up etc. dust-proof screen cloth in order to user.
Wherein, above-mentioned Preset Time is demarcated according to lot of experimental data, after the Preset Time after finger is removed, is led to
Normal influence of the finger to the real-time impedance value of speaker system can disappear, it is ensured that the now tool of the real-time impedance of speaker system
