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 some, not all, embodiments of the present invention. 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.
Referring to fig. 1, a flowchart of a method for acquiring geographic information according to an embodiment of the present invention is shown, and is applied to a mobile terminal, where the mobile terminal includes a player, and the method includes:
step S1: an input for obtaining geographic information is received.
If the user is in a certain environment and the user wants to view geographic information of the current environment, such as atmospheric pressure information, altitude information, and the like, input for acquiring the geographic information can be performed in the mobile terminal.
The method comprises the steps that the acquired geographic information exists in a terminal function mode, and a user inputs the acquired geographic information in the mobile terminal, namely the user starts the function; or, the acquired geographic information exists in a software form, and the user inputs the acquired geographic information in the mobile terminal, namely, the user clicks to enter a corresponding interface.
Step S2: in response to the input, the player is controlled to play the test sound signal.
In this step, in response to the input, the mobile terminal sends a test sound signal to the player and controls the player to play the test sound signal.
Preferably, the test sound signal is a digital test sound signal.
Further, before the player plays the test sound signal, the power amplifier may perform an amplification conversion process on the test sound signal, and then the test sound signal is played by the player to generate a sound loudness. In further embodiments, the player may include a power amplifier.
Step S3: and acquiring playing information generated by the player in playing the test sound signal.
When playing the test sound signal, the player will generate a series of information, and in this step, the playing information generated during playing is obtained.
The playing information comprises dynamic information generated in the playing process, such as voltage value information, current value information and the like; the playing information also includes fixed basic parameters, such as parameters related to the player itself.
Step S4: and obtaining the geographic information of the current position of the mobile terminal according to the playing information.
Because corresponding atmospheric pressure, air density and the like are different in different geographic environments, when the same sound signal is played by the player, the difficulty degree of pushing air is different, so that the vibrating diaphragm 3 in the player is pushed out by different amplitudes under the action of the same voltage, and playing information is different.
By using the characteristic of the player, the geographic information of the current position of the mobile terminal can be obtained according to the difference of the playing information of the player in different geographic environments.
In the embodiment of the invention, the user can input the operation of acquiring the geographic information of the current position in the mobile terminal, so that the mobile terminal receives the input of acquiring the geographic information and controls the player to play a section of test sound signal in response to the input. In the process of playing the test sound signal by the player, a series of playing information is generated so as to obtain the playing information, and the geographical information of the current position of the mobile terminal is finally obtained after a series of deduction calculation according to the currently generated playing information based on the difference of the playing information generated by different geographical information. Therefore, in the embodiment, based on the player of the mobile terminal, the geographic information of the current position, such as the atmospheric pressure information, the altitude information and other geographic information of the current position, can be obtained by using the principle characteristics of the player, so that expensive devices such as an air pressure sensor and a height sensor are prevented from being arranged in the mobile terminal, and meanwhile, the newly added devices are prevented from occupying the space of the mobile terminal, so that the material cost is reduced, the processing cost is also reduced, and the cost of the mobile terminal is reduced.
On the basis of the embodiment shown in fig. 1, fig. 2 shows a flowchart of a method for acquiring geographic information according to another embodiment of the present invention, in this embodiment, the player is a moving-coil speaker.
Generally, a mobile terminal includes a player for implementing basic communication functions, such as playing a voice in a call; and can also be used to implement entertainment functions such as playing music files, video files.
Referring to fig. 3 and 4, a conventional player includes a moving-coil speaker including a coil 1, a magnet 2, and a diaphragm 3, the coil 1 being wound around the magnet 2, and the diaphragm 3 being connected to the coil 1. Fig. 3 shows a non-vibrating state of the speaker, and fig. 4 shows a vibrating state of the speaker. The working principle is as follows: when an alternating audio current passes through the coil 1 of the loudspeaker, a corresponding magnetic field is generated in the coil 1, and the magnetic field generated by the magnet 2 of the loudspeaker generate an interaction force, the interaction force makes the coil 1 vibrate along with the audio current in the magnetic field generated by the magnet 2, and the coil 1 and the diaphragm 3 are connected together, so that the diaphragm 3 also vibrates (in a vibration state as shown in fig. 4), and the diaphragm 3 generates sound with the same waveform as the original audio signal.
On the basis of the above, as the environment changes, the atmospheric pressure in the corresponding environment may change. Under the same voltage, the corresponding atmospheric pressure changes, and the vibration amplitude of the diaphragm 3 also changes. In this embodiment, the vibration amplitude of the diaphragm 3 is normal based on the standard atmospheric pressure, that is, under the standard atmospheric pressure. When the atmospheric pressure is reduced, the density of the air is relatively small, the loudspeaker can push the air more easily, and the vibrating diaphragm 3 is pushed out to have larger amplitude under the same voltage; when the atmospheric pressure increases, the density of the air is relatively high, and the loudspeaker is difficult to push the air, and the diaphragm 3 is pushed out by a smaller amplitude under the same voltage.
In this embodiment, after the atmospheric pressure is changed, the amplitude of the diaphragm 3 is changed, so that the diaphragm 3 drives the coil 1 to generate a deformation characteristic different from the standard atmospheric pressure, and the current atmospheric pressure and altitude are obtained. Thus, the geographic information includes atmospheric pressure information and altitude information.
Preferably, step S4 includes:
step S41: and obtaining the abnormal deformation quantity of the coil generated in the playing test sound signal by the player according to the playing information.
In the step, when the test sound signal is played under the current atmospheric pressure, the abnormal deformation quantity of the coil is obtained.
The "coil abnormal deformation amount" herein refers to a deformation amount of the coil 1 which is different from the normal atmospheric pressure.
Step S42: and obtaining the atmospheric pressure information of the current position of the mobile terminal according to the coil abnormal deformation and the coil standard deformation.
The coil standard deformation is the coil deformation generated in the player playing the test sound signal under the standard atmospheric pressure.
If the standard deformation quantity of the coil generated in the test sound signal played by the player under the standard atmospheric pressure is zero, the variation quantity of the atmospheric pressure at the current position of the mobile terminal relative to the standard atmospheric pressure is obtained according to the abnormal deformation quantity of the coil.
Since the amplitude of the vibration of the diaphragm 3 is normal under the standard atmospheric pressure, the corresponding coil standard deformation amount is zero, and thus, in this step, the variation amount of the current atmospheric pressure with respect to the standard atmospheric pressure can be obtained based on the coil abnormal deformation amount obtained in step S42.
If the deformation of the coil 1 is increased compared with the normal deformation of the coil 1 due to the abnormal deformation of the coil 1, it indicates that the amplitude of the diaphragm 3 is increased, and the current atmospheric pressure is reduced compared with the standard atmospheric pressure, so that the atmospheric pressure at the current position of the mobile terminal can be obtained according to the reduced variation and the standard atmospheric pressure.
If the deformation of the coil 1 is reduced compared with the normal deformation of the coil 1 due to the abnormal deformation of the coil 1, it indicates that the amplitude of the diaphragm 3 is reduced, and the current atmospheric pressure is increased compared with the standard atmospheric pressure, so that the atmospheric pressure at the current position of the mobile terminal can be obtained according to the increased variation and the standard atmospheric pressure.
Step S43: and obtaining the altitude information of the current position of the mobile terminal according to the atmospheric pressure information.
According to the obtained atmospheric pressure information and the relationship between the atmospheric pressure information and the altitude information, the current altitude information can be obtained.
In this embodiment, the structural characteristics and the working principle of the moving-coil speaker are utilized to obtain the information and the generated signals of the speaker, so as to indirectly calculate the atmospheric pressure and the altitude, further replace an air pressure sensor and a height sensor applied in an intelligent mobile terminal, and save more cost and space of the mobile terminal. Therefore, on the premise of ensuring the cost, the embodiment of the invention reserves the novel function of acquiring the geographic information, conforms to the artificial intelligence concept, improves the value of the mobile terminal and enables the mobile terminal to be more intelligent.
In further embodiments, the player is not limited to moving coil speakers, but may be other types of speakers.
On the basis of the embodiment shown in fig. 2, fig. 5 is a flowchart illustrating a method for acquiring geographic information according to another embodiment of the present invention, where the playing information includes current value information and voltage value information, and step S41 includes:
step S411: and obtaining the corresponding instantaneous maximum impedance of the player in playing the test sound signal according to the current value information and the voltage value information.
After the atmospheric pressure changes, the amplitude changes, so that the diaphragm 3 drives the coil 1 to generate deformation different from the standard atmospheric pressure, and correspondingly, the impedance of the deformed coil 1 also changes. Therefore, in the present embodiment, the amount of coil abnormal deformation of the coil 1 is indirectly obtained by using the impedance of the coil 1.
In this step, current value information and voltage value information in the playback information are obtained, and according to a formula one: rmax is U/I, and instantaneous maximum impedance is obtained; wherein Rmax is the instantaneous maximum impedance, U is the voltage value information passing through the player, and I is the current value information passing through the player.
Step S412: and obtaining the impedance variation according to the corresponding standard maximum impedance and the instantaneous maximum impedance in the test sound signal played by the player under the standard atmospheric pressure.
In this step, according to formula two: obtaining an impedance change amount by taking the delta R as Rmax-Rnomal; where Δ R is the impedance variation and Rnormal is the standard maximum impedance.
The standard maximum impedance is the corresponding standard maximum impedance when the player plays the same test sound signal under the standard atmospheric pressure.
Step S413: and obtaining the abnormal deformation quantity of the coil generated in the playing test sound signal of the player according to the impedance variation quantity.
In this step, the following formula is given: r ═ p × L)/S, the formula four can be derived: obtaining the abnormal deformation quantity of the coil by L/S ═ DeltaR (S/p); wherein S is the cross-sectional area of the coil 1, p is the resistivity, L is the length of the coil 1, and L/S is taken as the abnormal deformation amount of the coil.
For a loudspeaker arranged on a mobile terminal, the cross section area of the coil 1 and the resistivity of the coil 1 are fixed parameters, so that the abnormal deformation quantity of the coil can be obtained according to the impedance change quantity calculated in the previous step.
On the basis of the embodiment shown in fig. 5, fig. 6 shows a flowchart of a method for acquiring geographic information according to another embodiment of the present invention, and after step S412, the method further includes:
step S414: and if the instantaneous maximum impedance is detected to be greater than the standard maximum impedance, determining that the atmospheric pressure at the current position of the mobile terminal is less than the standard atmospheric pressure.
Step S415: and if the instantaneous maximum impedance is detected to be smaller than the standard maximum impedance, determining that the atmospheric pressure of the current position of the mobile terminal is greater than the standard atmospheric pressure.
In this embodiment, the obtained instantaneous maximum impedance may be compared with the standard maximum impedance to determine whether the atmospheric pressure at the current location of the mobile terminal is increased or decreased relative to the standard atmospheric pressure, so that in the subsequent calculation: if the atmospheric pressure of the current position of the mobile terminal is reduced relative to the standard atmospheric pressure, the atmospheric pressure of the current position of the mobile terminal is obtained by subtracting the impedance variable quantity from the standard atmospheric pressure; and if the atmospheric pressure of the current position of the mobile terminal is increased relative to the standard atmospheric pressure, obtaining the atmospheric pressure of the current position of the mobile terminal by adding the impedance variable quantity to the standard atmospheric pressure.
The method is applied to the formula II: in the case that the delta R is greater than 0, the atmospheric pressure of the current position of the mobile terminal is reduced relative to the standard atmospheric pressure; if the delta R is less than 0, the atmospheric pressure of the current position of the mobile terminal is increased relative to the standard atmospheric pressure; and if the delta R is 0, the atmospheric pressure of the current position of the mobile terminal is the standard atmospheric pressure.
On the basis of the above embodiment, step S42 includes:
according to the formula five: obtaining the variation of the atmospheric pressure of the current position of the mobile terminal relative to the standard atmospheric pressure; where n is the variation and a is the fixed multiplier of coil 1.
In this step, according to experiments, when the coil abnormal deformation amount (L/S) is M meters, the corresponding atmospheric pressure variation amount is NKpa, so that a relationship between the coil abnormal deformation amount and the atmospheric pressure variation amount can be derived: L/S-n-a, where a is a fixed multiplier of coil 1, which value can be written into the mobile terminal.
Combining the second formula: Δ R ═ Rmax-Rnormal, formula five is variable as: when n is-L/(S × a), that is, Δ R >0, the atmospheric pressure decreases, and the corresponding variation n is a negative value.
Preferably, step S42 further includes:
according to the formula six: obtaining the atmospheric pressure when Pa is P + n; wherein Pa is atmospheric pressure, and P is standard atmospheric pressure.
Preferably, step S43 includes:
according to the formula seven:
obtaining the altitude; wherein Pa is atmospheric pressure, and H is altitude.
When the elevation increases, the atmospheric pressure can be reduced, the diaphragm 3 can generate deformation different from that under the standard atmospheric pressure, the loudspeaker coil 1 attached below the diaphragm 3 can also generate corresponding deformation, and the impedance of the loudspeaker coil 1 can also change at the moment. Therefore, the altitude in the same environment has a certain relationship with the atmospheric pressure.
In this step, after obtaining the local atmospheric pressure, the altitude can be indirectly calculated according to the relationship between the atmospheric pressure and the altitude (the empirical formula shown in formula seven), so as to achieve the effect of the atmospheric pressure and the altitude of the geographical location where the user needs to be located.
It should be noted that the atmospheric pressure appearing in the embodiment may be understood as the atmospheric pressure of the current location of the mobile terminal, in combination with the context.
Preferably, the player comprises a speaker or an earpiece.
The player can be a loudspeaker or a receiver arranged in the mobile terminal, and both can achieve the playing effect in all the embodiments of the invention.
With the popularization and common use of mobile terminals, it has become a habit for people to use mobile terminals. When users in various regions around the world use the mobile terminal, the use of a loudspeaker or a receiver cannot be avoided, and the use scenes of various regions exist. When a user is at a high altitude of ten thousand meters and at a deep sea of more than one thousand meters under water, anyone wants to take out the mobile phone to take a plurality of photos or share the mood with family and friends at the moment. Therefore, by combining the invention, the loudspeaker or the receiver can be used as basic equipment for acquiring the geographic information, thereby meeting more requirements of users.
