Background
The vibration mode is a common reminding information mode in the current mobile terminal, and under some special conditions, for example, in a noisy environment or a loudspeaker is blocked, the vibration mode can play a more effective reminding effect compared with a sound reminding mode.
Specifically, in the method for currently starting the vibration mode, besides manual starting by a user, the environment where the mobile terminal is located can be judged by using the distance sensor and the light sensor, so that the vibration mode of the mobile terminal is automatically started when the environment where the mobile terminal is located is dark or is attached to an object.
However, the conventional means for turning on the vibration mode is too simple and the recognition is not accurate. For example, when a mobile terminal is placed on a desktop, the mobile terminal may turn on a vibration mode as long as something covers a distance sensor or a light sensor, and in this case, the vibration mode is not required to be turned on.

First embodiment
Referring to fig. 1, an embodiment of the present invention provides a method for starting a vibration mode, which is applied to a mobile terminal having a speaker, and includes steps 101 to 103, which are described in detail below.
Step 101: and acquiring the characteristic change information of the sound emitted by the loudspeaker.
In the embodiment of the present invention, the characteristic change information may be related information used for determining whether the sound emitted by the speaker can be normally transmitted outside the mobile terminal, or may be related information used for determining whether the mobile terminal is in a noisy environment, which is not limited to this.
The mobile terminal is, for example, a mobile phone with an intelligent power amplification function, an iPad and the like, and can perform information reminding by using a vibration mode.
Step 102: and judging whether the characteristic change information meets a preset condition for starting a vibration mode of the mobile terminal.
In the embodiment of the present invention, according to the characteristic change information obtained in step 101, it can be determined whether the sound emitted by the speaker can be transmitted out of the mobile terminal normally, or whether the mobile terminal is in a noisy environment, or the like, that is, whether the sound prompt of the mobile terminal is blocked is determined, so as to determine whether to start the vibration mode of the mobile terminal.
Specifically, when the sound that the speaker sent can not normally spread out outside the mobile terminal, perhaps the mobile terminal is in noisy environment, whether mobile terminal's sound is reminded and is blocked, characteristic change information satisfies and opens mobile terminal's vibration mode's preset condition.
Step 103: and if the characteristic change information meets the preset condition, starting a vibration mode of the mobile terminal.
That is to say, when the characteristic change information meets the preset condition for starting the vibration mode of the mobile terminal, the mobile terminal automatically starts the vibration mode so as to utilize vibration to remind information and enhance the reminding effect.
According to the method for starting the vibration mode, whether the characteristic change information meets the preset condition for starting the vibration mode of the mobile terminal is judged by acquiring the characteristic change information of the sound emitted by the loudspeaker, the vibration mode of the mobile terminal is started when the characteristic change information meets the preset condition, whether the vibration mode of the mobile terminal needs to be started can be determined by means of the sound emitted by the loudspeaker, a means for starting the vibration mode is added, the identification precision is improved, and the vibration mode of the mobile terminal can be started under the condition that the sound reminding is blocked.
Second embodiment
Referring to fig. 2A, an embodiment of the present invention further provides a method for starting a vibration mode, which is applied to a mobile terminal having a speaker, and includes steps 201 to 206, which are described in detail below.
Step 201: and acquiring frequency information of the sound emitted by the loudspeaker.
In the embodiment of the invention, when the mobile terminal has the incoming call, unread information or messages, the mobile terminal can send out sound to remind through the loudspeaker according to the terminal setting. The frequency information obtained in step 201 is the frequency information of the sound emitted by the speaker in the current state.
Step 202: and determining an impedance characteristic curve of the loudspeaker according to the frequency information.
Specifically, the voice coil of the loudspeaker is a coil formed by winding enameled wires, and the voice coil not only has certain direct current resistance, but also has inductance of the voice coil. The voice coil moves in the magnetic air gap, cuts magnetic lines of force, and is a generator, which induces an induced voltage opposite to the voice signal, and attenuates the voice signal current in the voice coil, so that the impedance of the voice coil increases, and the increase becomes larger and larger along with the increase of the frequency of the voice signal.
The impedance characteristic of the loudspeaker refers to a rule that the impedance of a loudspeaker system changes along with the frequency change of a sound signal, and an impedance-frequency coordinate graph describing the impedance characteristic of the loudspeaker is an impedance characteristic curve.
In the embodiment of the invention, after the frequency information of the sound emitted by the loudspeaker is acquired, the current impedance characteristic curve of the loudspeaker can be determined. A specific impedance characteristic curve can be seen in fig. 2B, for example.
Step 203: and determining the resonant frequency value of the loudspeaker according to the impedance characteristic curve.
Specifically, the loudspeaker has a natural resonant frequency point, FO for short, in a low frequency band, and the frequency value at the FO is the resonant frequency value of the loudspeaker. The resonant frequency value of the speaker can be obtained from the impedance characteristic curve of the speaker, and is a frequency value corresponding to the impedance value when the impedance value reaches a maximum value (i.e., an impedance peak) in the impedance characteristic curve for the first time.
Thus, after determining the current impedance characteristic of the loudspeaker in step 202, the value of the resonant frequency of the loudspeaker in the current state can be determined.
Step 204: and calculating a first difference value of the resonant frequency value and a preset resonant frequency value.
The resonant frequency values of the speakers are different due to different types of the speakers and different installation modes of the speakers in the mobile terminal. Moreover, if the loudspeaker is blocked, the sound pressure of the cavity of the loudspeaker is increased, so that the sound cannot be normally radiated, the impedance characteristic curve of the loudspeaker is influenced, and the resonant frequency value of the loudspeaker is increased.
In the embodiment of the present invention, the preset resonant frequency value is a frequency value corresponding to the maximum impedance value in the impedance characteristic curve when the speaker (the model and the installation mode are fixed) in the mobile terminal is not blocked in the normal state, for example, FO in fig. 2B0The corresponding frequency value.
The resonant frequency value determined in step 203 is, for example, the frequency value corresponding to FO' in fig. 2B, and is the corresponding resonant frequency value when the speaker is in the blocking state.
In an embodiment of the present invention, the characteristic change information is a difference value between the resonant frequency value and a preset resonant frequency value, that is, a first difference value.
Step 205: and judging whether the first difference value is larger than or equal to a preset threshold value.
In the embodiment of the present invention, the preset threshold value may be obtained through multiple tests, and is a maximum offset amount that the preset resonant frequency value is allowed to increase in order to ensure normal operation of the speaker when the speaker is in the blocking state, that is, an increase amount of the preset resonant frequency value cannot exceed the preset threshold value. Whether the vibration mode of the mobile terminal is to be started or not can be determined by judging whether the first difference value is larger than or equal to the preset threshold value or not.
That is to say, when the difference (i.e., the first difference) between the resonant frequency value and the preset resonant frequency value is greater than or equal to the preset threshold, it indicates that the speaker is in the blocking state and the sound cannot be normally emitted, and the vibration mode of the mobile terminal needs to be turned on.
Step 206: and if the first difference is larger than or equal to the preset threshold, starting a vibration mode of the mobile terminal.
In the embodiment of the present invention, the preset condition for starting the vibration mode of the mobile terminal is as follows: the first difference is greater than or equal to the preset threshold.
Thus, when the first difference is greater than or equal to the preset threshold, the vibration mode of the mobile terminal may be turned on. Otherwise, the vibration mode of the mobile terminal is not required to be started.
According to the method for starting the vibration mode, the frequency information of the sound emitted by the loudspeaker is obtained, the impedance characteristic curve of the loudspeaker is determined according to the frequency information, the resonant frequency value of the loudspeaker is determined according to the impedance characteristic curve, the first difference value between the resonant frequency value and the preset resonant frequency value is calculated, whether the first difference value is larger than or equal to a preset threshold value or not is judged, the vibration mode of the mobile terminal is started when the first difference value is larger than or equal to the preset threshold value, the vibration mode of the mobile terminal can be started when the loudspeaker is in a blocking state and the sound cannot be normally discharged, the means for starting the vibration mode is added, and the identification precision is improved.
Third embodiment
Referring to fig. 3A, an embodiment of the present invention further provides a method for starting a vibration mode, which is applied to a mobile terminal having a speaker, and includes steps 301 to 306, which are described in detail below.
Step 301: a first pulse code modulation value of a preset volume of sound emitted by the loudspeaker at a first moment is acquired.
Specifically, Pulse Code Modulation (PCM) is a technique for converting sound from an analog signal to a digital signal. Briefly, the principle of PCM is to sample an analog signal at a fixed frequency, the sampled signal looks like a series of consecutive pulses with different amplitudes on the waveform, the amplitudes of the pulses are quantized with a certain precision, and the quantized values are continuously output, transmitted, processed or recorded in a storage medium and converted into digital signals. These quantized values are pulse code modulation values, referred to as PCM values for short.
In this embodiment of the present invention, the first PCM value obtained in step 301 is a PCM value of a preset volume of a sound emitted by a speaker, and is only related to a terminal setting, and if the volume set by the terminal is changed, the corresponding PCM value is also changed.
Step 302: and recording the sound emitted by the loudspeaker through a microphone.
In the embodiment of the invention, the sound emitted by the loudspeaker needs to be recorded by a microphone to judge whether the sound emitted by the loudspeaker can be normally transmitted out of the mobile terminal or not, or whether the mobile terminal is in a noisy environment or not.
Step 303: a second pulse code modulation value of the volume of the recorded sound at a second time is obtained.
In the embodiment of the present invention, after the sound emitted from the speaker is recorded, PCM processing may be performed on the recorded sound to obtain a PCM value of the volume of the recorded sound.
Specifically, due to hardware delay, the recording time of the microphone is generally later than the emission time of the speaker for the same sound, and the time difference between the two is fixed and constant. In the embodiment of the present invention, the fixed time difference may be preset, for example, the fixed time difference is used as a preset time offset.
In this way, the difference between the second time and the first time is equal to the preset time offset, so as to ensure that the same sound is aimed at in the subsequent processing process.
Step 304: when the first pulse code modulation value is greater than the second pulse code modulation value, calculating a second difference value between the first pulse code modulation value and the second pulse code modulation value.
In this embodiment of the present invention, the characteristic change information is a difference between the first pulse code modulation value and the second pulse code modulation value, that is, a second difference, and is used to determine whether the speaker is in a blocking state and sound cannot be normally played.
Step 305: and judging whether the second difference value is greater than or equal to a first preset pulse code modulation value or not.
In an embodiment of the present invention, the first preset pulse code modulation value is obtained through a plurality of tests, and is a critical value of a difference between the first pulse code modulation value and the second pulse code modulation value, that is, the difference between the first pulse code modulation value and the second pulse code modulation value cannot exceed the first preset pulse code modulation value, in order to ensure normal operation of the speaker when the speaker is in a blocking state. Whether the vibration mode of the mobile terminal needs to be started or not can be determined by judging whether the second difference value is larger than or equal to the first preset pulse code modulation value or not.
For example, for the same sound, the first time t1Obtaining a first PCM value of a preset volume at a second time t2Recording the sound emitted by the loudspeaker through the microphone, wherein the corresponding PCM value is a second PCM value, and t2And t1Is equal to a predetermined time offset t0(i.e. t)2－t1﹦t0) (ii) a And when the difference value (second difference value) between the first PCM value and the second PCM value is greater than or equal to the first preset PCM value, it indicates that the speaker is in a blocking state and the sound cannot be normally played, and the vibration mode of the mobile terminal needs to be started.
Step 306: and if the second difference value is greater than or equal to the first preset pulse code modulation value, starting a vibration mode of the mobile terminal.
In the embodiment of the present invention, the preset condition for starting the vibration mode of the mobile terminal is as follows: the second difference is greater than or equal to the first preset pulse code modulation value.
In this way, when the second difference is greater than or equal to the first preset pulse code modulation value, the vibration mode of the mobile terminal may be turned on. Otherwise, the vibration mode of the mobile terminal is not required to be started.
In the embodiment of the present invention, referring to fig. 3B, on the basis of steps 301 to 303, the method for starting the vibration mode may further include steps 307 and 309, which are described in detail below.
Step 307: when the second pulse code modulation value is greater than the first pulse code modulation value, calculating a third difference value between the second pulse code modulation value and the first pulse code modulation value.
In the embodiment of the present invention, the characteristic change information is a difference between the second pulse code modulation value and the first pulse code modulation value, that is, a third difference, and is used to determine whether the speaker is in a noisy environment and a sound reminding effect is not obvious.
Step 308: and judging whether the third difference value is greater than or equal to a second preset pulse code modulation value.
In the embodiment of the present invention, the second preset pulse code modulation value may also be obtained through multiple tests, and in order to ensure normal operation of a speaker when the mobile terminal is in a noisy environment, a critical value of a difference between the second pulse code modulation value and the first pulse code modulation value is allowed, that is, the difference between the second pulse code modulation value and the first pulse code modulation value cannot exceed the second preset pulse code modulation value. And determining whether to start the vibration mode of the mobile terminal by judging whether the third difference value is greater than or equal to the second preset pulse code modulation value.
For example, for the same sound, the first time t1Obtaining a first PCM value of a preset volume at a second time t2Recording the sound emitted by the loudspeaker through the microphone, wherein the corresponding PCM value is a second PCM value, and t2And t1Is equal to a predetermined time offset t0(i.e. t)2－t1﹦t0) (ii) a And when the difference value (third difference value) between the second PCM value and the first PCM value is greater than or equal to the second preset PCM value, the mobile terminal is in a noisy environment, the sound reminding effect is not obvious, and the vibration mode of the mobile terminal needs to be started.
Step 309: and if the third difference is greater than or equal to the second preset pulse code modulation value, starting a vibration mode of the mobile terminal.
In the embodiment of the present invention, the preset condition for starting the vibration mode of the mobile terminal is as follows: the third difference is greater than or equal to the second preset pulse code modulation value.
In this way, when the third difference is greater than or equal to the second preset pulse code modulation value, the vibration mode of the mobile terminal may be turned on. Otherwise, the vibration mode of the mobile terminal is not required to be started.
The method for starting the vibration mode of the embodiment of the invention obtains the first pulse code modulation value of the preset volume of the sound emitted by the loudspeaker at the first moment, recording the sound emitted by the loudspeaker through a microphone, acquiring a second pulse code modulation value of the volume of the recorded sound at a second moment, when the first pulse code modulation value is larger than the second pulse code modulation value, calculating a second difference value between the first pulse code modulation value and the second pulse code modulation value, judging whether the second difference value is larger than or equal to a first preset pulse code modulation value or not, when the second difference value is greater than or equal to the first preset pulse code modulation value, the vibration mode of the mobile terminal is started, and when the loudspeaker is in a blocking state and sound cannot be normally played out, the vibration mode of the mobile terminal can be started; and simultaneously when the second pulse code modulation value is greater than the first pulse code modulation value, calculating the second pulse code modulation value and the third difference value of the first pulse code modulation value, judging whether the third difference value is greater than or equal to the second preset pulse code modulation value, and opening the vibration mode of the mobile terminal when the third difference value is greater than or equal to the second preset pulse code modulation value, so that the vibration mode of the mobile terminal can be opened when the loudspeaker is in a noisy environment and the sound reminding effect is not obvious, the means for starting the vibration mode is increased, and the identification precision is also improved.
