Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It is to be noted that the terms "comprises" and "comprising" and any variations thereof in the embodiments and drawings of the present invention are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

The embodiment of the invention discloses a loudspeaker liquid drainage method based on gain adjustment and electronic equipment, which can improve the liquid drainage capability of a loudspeaker. The following are detailed below.

Example one

Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a speaker liquid discharging method based on gain adjustment according to an embodiment of the present invention. The method for draining liquid by using a speaker based on gain adjustment described in fig. 1 is suitable for electronic devices with speakers, such as mobile phones, smart watches, smart bracelets, tablet computers, and home education machines, and the embodiment of the present invention is not limited thereto. The operating system of the electronic device may include, but is not limited to, an Android operating system, an IOS operating system, a Symbian operating system, a blackberry operating system, a Windows Phone8 operating system, and the like. As shown in fig. 1, the speaker draining method based on gain adjustment may include the following steps:

101. after detecting a request for draining liquid to a loudspeaker of the electronic equipment, the electronic equipment adjusts a current signal gain value when the loudspeaker plays an audio signal to a first signal gain value. In the embodiment of the present invention, the request for discharging liquid from the speaker detected by the electronic device may be triggered by a user of the electronic device, or may be automatically triggered by the electronic device after detecting that the residual liquid exists in the speaker by using a humidity sensor, and the like, which is not limited in the embodiment of the present invention.

The signal gain when the speaker plays audio refers to the amplification factor of the audio signal, and under the condition that the input power of the audio signal is the same, the larger the signal gain is, the higher the output power of the audio signal is, the larger the energy generated when the speaker plays the audio is, and the higher the probability that water is discharged from the speaker through the vibration of the speaker is. Generally, a volume knob or a volume knob of a speaker can be adjusted only within a range of an output power of an audio signal. For example, assuming that the output power of an audio signal to a speaker is 80W, the volume adjustment button can only adjust the actual output power of the speaker when outputting sound finally within the range of 0-80W. Therefore, in the case where the output power of the audio signal to the speaker is low, even if the current volume level of the electronic device is set to the highest level, the vibration strength of the speaker may be insufficient to discharge the liquid from the speaker. In the embodiment of the invention, the first signal gain value can be higher than the current signal gain value, and if the volume level of the electronic equipment is kept unchanged, the output power is higher when the first audio is played according to the first signal gain value, so that liquid such as water and the like can be discharged from the loudspeaker. Further, when the user uses the speaker, there is less probability that the volume level of the electronic device is set to the highest level, and therefore, the actual output power of the speaker when playing audio is generally lower than the output power of the audio signal when outputting to the speaker. If the signal gain is not adjusted prior to playing the audio for draining, the user may need to manually adjust the current volume level of the electronic device to a maximum level in order to ensure that the actual output power of the speaker is sufficiently large (i.e., water can be drained from the speaker by vibration). In the embodiment of the invention, the electronic equipment adjusts the signal gain to the higher first signal gain value, so that the operation steps of manually adjusting the volume level by a user can be reduced, the operation process of the user is simplified, and the user experience is improved.

It should be noted that, in the embodiment of the present invention, the first signal gain value may also be equal to or lower than the current signal gain value, and the electronic device may calculate the first signal gain value by combining the input power of the first audio signal source signal, the current volume level of the speaker, the lowest output power of the speaker when the liquid is discharged from the speaker, and the like, which is not limited in the embodiment of the present invention. The electronic equipment can improve the liquid discharge capacity of the loudspeaker by adaptively adjusting the signal gain, can shorten the time for playing audio under the condition of overhigh gain, and reduces the probability of damage to the loudspeaker.

102. The electronic equipment controls the loudspeaker to play the first audio signal with a specific frequency according to the first signal gain value, so that the liquid is discharged from the loudspeaker through vibration when the loudspeaker plays the first audio signal.

In the embodiment of the present invention, the specific frequency may be a frequency outside the range of human ear hearing (e.g. lower than 20Hz, or higher than 20000 Hz); alternatively, the specific frequency can be found experimentally: when the specific frequency is a certain value, the drainage effect of the loudspeaker is optimal; the specific frequency can also be selected by the user, the user can select the frequency of the first audio signal to be played through a touch screen of the electronic device, and the frequency can also be selected through triggering of a key or a gesture.

In the embodiment of the present invention, the first audio signal may be any one of a plurality of sine waves coupled to form a sine wave, a square wave, a triangular wave, a sawtooth wave, or any other waveform. The first audio signal may in particular be a square wave signal; the square wave signal changes from high amplitude to low amplitude and from low amplitude to high amplitude suddenly, when the loudspeaker plays the square wave signal, the vibration of the diaphragm changes from minimum amplitude to maximum amplitude in a very short time, and the thrust generated by the vibration of the diaphragm is relatively large, so that the liquid is more favorably discharged from the loudspeaker.

It can be seen that in the method depicted in fig. 1, the electronic device automatically adjusts the current signal gain value to a first signal gain value upon detecting a liquid discharge request to the speaker; when the first signal gain value is higher than the current signal gain value, the liquid is discharged from the loudspeaker through the vibration of the loudspeaker during broadcasting, and the operation steps of manually adjusting the volume level by a user are reduced; when the first signal gain is lower than the current signal gain, it is advantageous to reduce the probability that the loudspeaker is damaged. Further, in the method described in fig. 1, the first audio signal may be a square wave signal, and when the square wave signal is played, the thrust generated by the loudspeaker due to the vibration of the diaphragm is relatively large, which is more favorable for discharging the liquid from the loudspeaker.

Example two

Referring to fig. 2, fig. 2 is a schematic flow chart illustrating another speaker liquid draining method based on gain adjustment according to an embodiment of the present invention. As shown in fig. 2, the speaker draining method based on gain adjustment includes the following steps:

201. after detecting a request for draining liquid to a loudspeaker of the electronic equipment, the electronic equipment adjusts a current signal gain value when the loudspeaker plays an audio signal to a first signal gain value.

202. The electronic equipment controls the loudspeaker to play the first audio signal with a specific frequency according to the first signal gain value, so that the liquid is discharged from the loudspeaker through vibration when the loudspeaker plays the first audio signal.

In the embodiment of the present invention, in the process of executing step 202, the electronic device may further execute the following steps:

the electronic equipment controls the microphone to record while the loudspeaker plays the first audio signal so as to obtain a second audio signal;

the electronic equipment determines the liquid residual quantity of the loudspeaker at the current moment by analyzing the volume of the second audio signal;

and the electronic equipment judges whether the signal gain value needs to be adjusted or not according to the liquid residual quantity, if so, a second signal gain value corresponding to the liquid residual quantity is obtained, and the second signal gain value is used as the first signal gain value. And after the electronic equipment takes the second signal gain value as the first signal gain value, continuing to play the first audio signal according to the adjusted first signal gain value.

In the embodiment of the present invention, in the process of executing step 202, the electronic device may detect the liquid residual amount of the speaker through the above steps at fixed time intervals, and accordingly, the manner of determining whether the signal gain value needs to be adjusted according to the liquid residual amount by the electronic device may include: the electronic equipment acquires the liquid residual quantity of the loudspeaker at the last moment before the current moment; the electronic equipment compares the liquid residual quantity at the previous moment with the liquid residual quantity at the current moment to determine the change value of the liquid residual quantity; the electronic equipment judges whether the change value of the residual liquid quantity is higher than a certain threshold value, if so, the judgment result of the electronic equipment is that the signal gain value does not need to be adjusted, and if not, the judgment result of the electronic equipment is that the signal gain value needs to be adjusted. When the vibration dynamics of speaker is not enough, the speed of discharge liquid slows down, and electronic equipment can monitor the speed of speaker discharge liquid through the change value of the liquid volume of remaining to can in time adjust the signal gain value when liquid discharge speed slows down, and then be favorable to improving flowing back efficiency.

In addition, the electronic device can play the first audio signal when the loudspeaker is dry, and control the microphone to receive the first audio signal to obtain a standard audio signal; the electronic device may set the volume level of the standard audio signal to a standard volume value. When the electronic device drains liquid from the speaker in step 202, the liquid residual amount of the speaker at the current time is determined according to the difference between the volume of the second audio signal received by the microphone and the standard volume value. Generally, the larger the volume difference, the larger the amount of liquid remaining at the current moment of the speaker due to the influence of the liquid on the diaphragm of the speaker or the influence of the liquid on the absorption of sound, and the like. The electronic equipment can inquire out the liquid residual quantity corresponding to the current volume difference value through the corresponding relation between the volume difference value and the liquid residual quantity, so that a second signal gain value corresponding to the current liquid residual quantity is determined.

Through executing the steps, the electronic equipment can dynamically adjust the signal gain according to the liquid residual quantity of the loudspeaker in the process of draining the liquid by playing the first audio signal through the loudspeaker, so that the duration time of playing the audio through the loudspeaker according to the high signal gain can be reduced, and the power consumption of the loudspeaker in the draining process is further reduced.

203. The electronics control the speaker to stop the draining operation.

In an embodiment of the present invention, the controlling, by the electronic device, the speaker to stop the liquid discharge operation may include: the electronic device controls the speaker to stop playing the first audio signal of the specific frequency.

204. The electronic device adjusts the first signal gain value to a regular signal gain value.

In the embodiment of the invention, the conventional signal gain value is a critical value for keeping the audio undistorted when the speaker plays the audio signal by presetting the highest audio level. When the loudspeaker performs liquid discharge operation, the signal gain of audio playing can be improved, and the probability of audio distortion is high. As an alternative embodiment, the frequency of the first audio signal may be outside the range of audible frequencies of the human ear, and the signal distortion when the first audio signal is played by the speaker is not noticeable to the user. After the liquid discharging operation of the speaker is finished, if the signal gain of the speaker is not adjusted, when the speaker plays audio with a frequency within the hearing range of human ears, a user may perceive the audio distortion, thereby affecting the hearing experience of the user.

Therefore, in the embodiment of the invention, after the liquid discharging operation of the loudspeaker is stopped, the electronic equipment adjusts the first signal gain value to the conventional signal gain value, so that the distortion condition of the loudspeaker when the loudspeaker plays the audio signal in the auditory range of human ears is reduced, and the influence on the conventional audio playing is reduced.

It can be seen that in the method described in fig. 2, after the speaker stops the liquid discharge operation, the electronic device restores the signal gain value to the normal signal gain value, so that the distortion of the speaker during playing the audio signal in the hearing range of human ears can be reduced, and the influence on normal audio playing can be reduced. Furthermore, the electronic equipment can dynamically adjust the signal gain according to the liquid residual quantity of the loudspeaker in the process of controlling the loudspeaker to play the first audio signal to drain liquid, so that the duration time of the loudspeaker to play audio according to the high signal gain can be reduced, and the power consumption of the loudspeaker in the draining process is further reduced.

EXAMPLE III

Referring to fig. 3, fig. 3 is a schematic flow chart of another speaker liquid draining method based on gain adjustment according to an embodiment of the present invention. As shown in fig. 3, the speaker draining method based on gain adjustment includes the following steps:

301. after detecting a request for draining liquid to a loudspeaker of the electronic equipment, the electronic equipment adjusts a current signal gain value when the loudspeaker plays an audio signal to a first signal gain value.

In this embodiment of the present invention, after the electronic device performs step 301 to adjust the current signal gain value to the first signal gain value, and before performing step 302, the electronic device may further perform the following steps:

the electronic device obtains the maximum output power of the speaker, and judges whether the output power of the first audio signal output to the speaker exceeds the maximum output power according to the input power of the first audio signal to be played and the first signal gain value, if not, the electronic device executes step 302; if the first audio signal exceeds the maximum output power, the electronic device decreases the signal gain value until the output power of the first audio signal output to the speaker does not exceed the maximum output power, and performs step 302 by using the signal gain value at this time as the first signal gain value. The electronic equipment executes the steps, so that the probability of damage to the loudspeaker caused by overlarge output power when the audio signal is output to the loudspeaker can be reduced.

302. The electronic equipment controls the loudspeaker to play the first audio signal with a specific frequency according to the first signal gain value, so that the liquid is discharged from the loudspeaker through vibration when the loudspeaker plays the first audio signal.

In an embodiment of the present invention, the first audio signal may be a square wave signal. In addition, in the process of executing step 202, the electronic device may further execute the following steps:

the electronic equipment controls the microphone to record while the loudspeaker plays the first audio signal so as to obtain a second audio signal; determining the liquid residual quantity of the loudspeaker at the current moment by analyzing the volume of the second audio signal; and judging whether the signal gain value needs to be adjusted or not according to the liquid residual quantity, if so, acquiring a second signal gain value corresponding to the liquid residual quantity, and taking the second signal gain value as a first signal gain value.

303. The electronic device determines whether a drainage end request triggered by a user of the electronic device is detected, if so, step 305 is executed, and if not, step 304 is executed.

In the embodiment of the present invention, the user may trigger the liquid discharge end request by clicking the touch screen, pressing a key, executing a specific action, and the like, which is not limited in the embodiment of the present invention. The electronic device executes the step 303, which allows the user to stop the liquid discharging operation of the speaker according to the user's own requirement, thereby improving the flexibility of the liquid discharging operation of the speaker.

304. The electronic device determines whether the playing time of the first audio signal played by the speaker exceeds a specified time threshold, if so, executes step 305, and if not, continues to execute step 302.

In the embodiment of the present invention, the electronic device executing step 305 is beneficial to reduce the duration of the audio played by the speaker under the condition of a high signal gain value, so as to be beneficial to reducing the risk of damage to the speaker.

305. The electronic device stops the liquid discharge operation of the speaker.

In the embodiment of the present invention, the electronic device performs steps 303 to 304, and determines whether the condition for stopping the liquid discharging operation of the speaker is satisfied, and if so, the electronic device performs step 305 to stop the liquid discharging operation of the speaker, so as to control the speaker to stop the liquid discharging operation. Wherein the electronic device stopping the liquid discharge operation of the speaker may include stopping the speaker from playing the first audio signal of the particular frequency.

306. The electronic device adjusts the first signal gain value to a regular signal gain value.

It can be seen that in the method described in fig. 3, the electronic device can improve the ability of the speaker to discharge liquid in the manner of playing audio by adjusting the signal gain value, and can also reduce the influence on other conventional audio plays that do not aim at discharging liquid. The electronic equipment can also improve the flexibility of the liquid discharging operation of the loudspeaker by detecting a liquid discharging finishing request triggered by a user, and reduce the risk of damage to the loudspeaker by monitoring the duration of the first audio signal played by the loudspeaker.

the determination unit 406 acquires the liquid remaining amount of the speaker at the previous time before the current time; the judgment unit 406 compares the liquid residual amount at the previous moment with the liquid residual amount at the current moment to determine a variation value of the liquid residual amount; the judging unit 406 judges whether the variation value of the residual amount of liquid is higher than a certain threshold, if so, the judging unit 406 judges that the signal gain value does not need to be adjusted, and if not, the judging unit 406 judges that the signal gain value needs to be adjusted.

Further, in the electronic apparatus shown in fig. 6:

the gain adjustment unit 401 is further configured to obtain a second signal gain value corresponding to the residual liquid amount when the determination unit 406 determines that the signal gain value needs to be adjusted, and use the second signal gain value as the first signal gain value.

That is to say, in the embodiment of the present invention, when the broadcasting unit 402 controls the speaker to play the first audio according to the first signal gain value, the gain adjusting unit 401 adjusts, in real time, the first signal gain value according to the determination of the determining unit 406: when the second determination unit 406 determines that the signal gain needs to be adjusted according to the liquid remaining amount of the speaker, the gain adjustment unit 401 adjusts the first signal gain value to a second signal gain value corresponding to the liquid remaining amount.

It can be seen that, with the electronic device shown in fig. 6, in the process of controlling the speaker to play the first audio signal for draining, the signal gain can be dynamically adjusted according to the liquid residual amount of the speaker, so that the duration of the speaker playing audio according to the high signal gain can be reduced, and the power consumption of the speaker in the draining process can be further reduced.
