Background
Nowadays, as the variety of mobile terminals (e.g., smart phones) is more and more abundant, the number of mobile terminal users is continuously increasing, and the application requirements of users for the mobile terminals are more and more, such as smart phones with waterproof function. Taking the smart phone with the waterproof function as an example, most of the current mainstream smart phones are full-touch screen phones, and most of the touch screens of the smart phones are capacitive screens. The capacitive screen relies on charge transfer to effect operation of the smartphone. Therefore, when the smartphone is in water, the touch screen of the mobile terminal may be disabled due to the conductivity of the water. Moreover, most smart phones are waterproof first mainly by being sleeved with a waterproof mobile phone case, and the capacitive screen realizes the operation of the smart phone by charge transfer, so that the operation of the smart phone cannot be realized by touching the touch screen through the waterproof mobile phone case.
Therefore, each existing large mobile phone manufacturer adds an underwater mode (for example, in the underwater mode, the smart phone controls the smart phone only through physical keys) option to the smart phone, and before the user places the smart phone in water, the user manually switches the mobile terminal from the working mode to the underwater mode, so that the smart phone operates normally. However, the whole process of this method requires manual switching by the user, the operation is cumbersome, and the switching speed is too slow.

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.
The terminal equipment in the embodiment of the invention is a mobile terminal with a waterproof function. Specifically, the mobile terminal may be a terminal device such as a smart phone, a tablet Computer, a notebook Computer, a super mobile Personal Computer (UMPC), a netbook, a Personal Digital Assistant (PDA), and the like, but is not limited thereto. The mobile terminal at least comprises a touch screen microphone and a loudspeaker, wherein the touch screen in the mobile terminal can be a capacitive screen or a resistive screen or other types of touchable screens, the microphone in the mobile terminal is used for receiving user voice and other audio signals, and the loudspeaker in the mobile terminal is used for outputting voice of a call partner and other audio signals. Typically, the microphone is typically on the left or right side of the speaker, or above the speaker.
The touch screen of the mobile terminal is used for controlling the mobile terminal in a normal state, and a user can realize the control of the mobile terminal by performing touch operation on the touch screen. And the normal state of the touch screen means that the user controls the mobile terminal using the touch screen in a general scene (for example, the mobile terminal is in the air and the touch screen of the mobile terminal is in an on state).
In addition, the mobile terminal described in this embodiment is underwater, which means that the mobile terminal is located below the water surface, and the mobile terminal is located below the water surface includes that the whole body of the mobile terminal is located below the water surface, or the body including the mobile terminal portion is located in water. Wherein the mobile terminal part body is located in water and the part of the touch screen including the mobile terminal is located in water.
The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
In the present embodiment, the words "first", "second", etc. are used for distinguishing them from each other unless the context clearly indicates that the order is to be construed.
An embodiment of the present invention provides a method for controlling a mobile terminal, as shown in fig. 1, the method includes the following steps:
101. when the mobile terminal detects a large-area conductor contact event through the touch screen, the mobile terminal controls the loudspeaker to output a first audio signal and acquires signal parameters of a second audio signal acquired by the microphone at the same time.
For example, when a mobile terminal (e.g., a mobile phone) is immersed in water, due to the conductivity of water, a touch event is reported to the mobile terminal after a plurality of ITO (conductive glass) electrodes of a capacitive touch screen sense a capacitance change, and a scenario in which a touch event is continuously triggered in a large area is defined as a large-area conductor contact event in the field of touch ICs (integrated circuits). Specifically, if there is simultaneous continuity in the sensor layer of the mobile terminal, the dense reporting contact event is regarded as a large-area conductor contact. Such continuous, dense and simultaneous contact events are unlikely to be triggered by a user finger touch (which can be demonstrated here in terms of the contact area of the finger and the underlying area of the Sensor electrodes).
Based on the above, in this embodiment, the mobile terminal determines whether to trigger the large-area conductor contact event by detecting the number of touch points reported by the touch screen, or the size of the area where the touch points are distributed, or the size of the density of the distribution of the touch points (that is, the ratio between the number of touch points and the area where the touch points are distributed). For example, the touch screen triggers a large area conductor contact event when the number of triggered touch points on the touch screen is greater than a second predetermined threshold and/or the area of the distribution of triggered touch points on the touch screen is greater than a third predetermined threshold.
And after the mobile terminal detects the large-area conductor contact event reported by the touch screen, the mobile terminal can disable the touch function of the touch screen of the mobile terminal and make further judgment. The user may have the screen and be stained with the condition such as water in the in-service use, and in order to distinguish the screen and be stained with the different condition that mobile terminal submerges completely, this application further confirms current mobile terminal's state through increasing the mode that mobile terminal control speaker sounded to detect the input of microphone.
102. The mobile terminal judges whether the signal parameter of the second audio signal meets a predetermined condition.
In the present embodiment, the signal parameters of the audio signal include parameter information such as frequency, amplitude, wavelength, and the like of the audio signal.
Specifically, when the signal parameters of all audio signals mentioned in this embodiment include the wavelength of the audio signal, step 103 specifically includes:
102b, the mobile terminal judges whether the wavelength of the second audio signal is larger than a first preset threshold value.
The first predetermined threshold is obtained by the wavelength of a third audio signal acquired by the microphone at the same time when the mobile terminal controls the loudspeaker to output the first audio signal according to the situation that the mobile terminal is in the air. Illustratively, when the mobile terminal is in the air, the mobile terminal is in a normal operation mode, and at this time, the third audio signal received by the microphone is the first audio signal output by the speaker of the mobile terminal in the air. Therefore, if the mobile terminal is in water, the second audio signal received by the microphone is the first audio signal output by the loudspeaker of the mobile terminal in water; if the mobile terminal is in the air, the second audio signal received by the microphone is the first audio signal output by the speaker of the mobile terminal in the air, which can be understood as a third audio signal.
Therefore, if the wavelength of the second audio signal is greater than the first predetermined threshold, it is determined that the second audio signal meets the predetermined condition, that is, the mobile terminal is in water; and if the wavelength of the second audio signal is less than or equal to a first preset threshold value, judging that the second audio signal is not in a preset condition, namely that the mobile terminal is in the air.
For example, when the mobile terminal detects a large-area conductor contact event through a touch screen, the mobile terminal emits a first audio signal with a frequency of 800hz through a Speaker, and collects a second audio signal at the frequency through a MIC (microphone).
By the acoustic formula, V ═ λ × f, it can be calculated that when the first audio signal is propagated in the air, the wavelength λ of the audio is 0.425m, and when the first audio signal is propagated under water, the wavelength λ of the audio is 1.688 m. Therefore, the mobile terminal judges whether the mobile terminal is in water or not by analyzing whether the audio wavelength acquired by the MIC is obviously increased or not. For the mobile phone with multiple MICs, the state of the mobile phone can be judged more accurately according to the audio data collected by the MIC at each position.
Since the wavelength of the audio is greatly different from the wavelength of the audio when the audio propagates through the air, the above-described method of determining whether or not the mobile terminal is located in water based on the wavelength of the audio is the most preferable method. However, the method of determining whether the mobile terminal is in water is not limited to this method, and for example, the mobile terminal may determine by determining the amplitude of the audio when it is propagated through the air and the amplitude when it is propagated through the water.
103. And if the signal parameter of the second audio signal meets a preset condition, the mobile terminal determines that the terminal equipment is positioned in water and controls the mobile terminal to start an underwater mode.
When the mobile phone is in the underwater mode, the mobile phone can be operated only through the entity keys, and when the mobile phone is in the underwater mode, the underwater mode is opened, and the mobile phone is operated by utilizing the entity keys. If the mobile phone is not completely located in the water (i.e., needs to exit the underwater mode), the mobile phone can prompt the user to exit the underwater mode in a mode of executing a specific user gesture (e.g., swinging the mobile phone). When the phone is taken out of the water, the user can exit the underwater mode by performing a specific user gesture, for example, by shaking the phone: on one hand, a user throws away water drops on the mobile phone, and on the other hand, the system can identify the throwing action of the user and quit the underwater mode.
Of course, after step 102, if the mobile terminal determines that the signal parameter of the second audio signal does not satisfy the predetermined condition, the mobile terminal determines that the terminal device is not completely located in the water, and controls the mobile terminal to close the underwater mode and automatically switch to the working mode, so that the function of the touch screen is restored to normal.
It should be noted that, because the audio signal is subjected to a large resistance when being transmitted underwater, the audio signal emitted by the speaker may be weak after reaching the microphone. Therefore, when the mobile terminal detects a large-area conductor contact event through the touch screen, the loudspeaker of the mobile phone is controlled to sound, and a signal returned by the microphone is detected, if no signal is returned by the microphone, the mobile phone is in a state of being immersed in water, at the moment, the predetermined condition is equivalent to that the second audio signal cannot be detected, namely when the microphone does not detect the second audio signal, the terminal device is determined to be located in water. Correspondingly, if the microphone can still collect the sound signal (i.e. when the microphone detects the second audio signal), it indicates that the mobile phone is not completely underwater, and is not switched to the underwater mode.
According to the control method of the mobile terminal provided by the embodiment of the invention, after the mobile terminal detects a large-area conductor contact event reported by a touch screen, the loudspeaker is controlled to output a first audio signal, signal parameters of a second audio signal acquired by the microphone at the same time are acquired, whether the signal parameters of the second audio signal meet preset conditions or not is judged, if the preset conditions are met, the terminal equipment is determined to be located in water, and the mobile terminal is controlled to start an underwater mode. Compared with the prior art that the mobile terminal is switched to the underwater mode from the working mode manually by the user, the method and the device for judging the underwater mobile terminal judge whether the current mobile terminal is in the water or not by analyzing the audio data of the audio signal received by the microphone of the mobile terminal in the water, if the mobile terminal is judged to be in the water, the user does not need to do any operation, the mobile terminal is automatically switched to the underwater mode, and therefore the user experience can be further improved while the false triggering caused by the fact that the screen is stained with the water is avoided.
