A method for microphone selection, applied in a mobile device having at least two microphones, the method includes: transmitting, by using an ultrasonic transmitter of the mobile device, first ultrasonic waves within a testing box, wherein the first ultrasonic waves are transmitted with a predefined transmission strength and at different frequencies selected from a predefined frequency range; acquiring, by using each of the at least two microphones to receive second ultrasonic waves reflected from the first ultrasonic waves within the testing box, frequency response values of the second ultrasonic waves received by each of the at least two microphones; and determining one of the at least two microphones which has a highest frequency response value, as a microphone for receiving ultrasonic waves for the mobile device.

Methods, devices, and computer-readable medium for microphone selection

A method, an electronic device, and a medium for controlling a state of a touch screen are provided. The method includes: detecting whether the touch screen is in a first preset state; determining whether induction information of a suspended object reaches a first set of preset thresholds, if the touch screen is not in the first preset state; and controlling the touch screen to be switched from a current state to the first preset state, if the induction information reaches the first set of preset thresholds.

Method for controlling state of touch screen, and electronic device and medium for implementing the same

A method and a device for restraining edge touches are provided. The device acquires locations of one or more touch points sensed by a terminal at two edges of a screen of the terminal. The device determines a holding manner indicating how the terminal is held according to the locations of the one or more touch points. When the holding manner is a single-hand holding manner indicating that the terminal is held by a single hand, the device determines to trigger a touch restraining detection in a restraining region at one edge of the screen corresponding to the single-hand holding manner, such that touch points sensed within the restraining region do not trigger the terminal to respond to operations input by a user.

Method and device for restraining edge touches

Methods and devices are provided for waking up a screen in the field of application of electronic technologies. The method may be implemented by a device including a screen and a frame at least partially surrounding the screen. In the method, the device activates at least one temperature transducer according to a predetermined sequence when the screen is in an off state, where the at least one temperature transducer is disposed at least partially in the frame. The device may obtain a temperature measurement through the activated temperature transducer. When any one of the temperature measurement is within a preset range of temperature, the device may trigger the screen to be switched from the off state to an on state.

Methods and devices for waking up a screen

The present disclosure relates to a method, device and storage medium for controlling a screen state. The method includes: transmitting an ultrasonic transmission-signal for N times within a preset time period when detecting that an ultrasonic sensing function of the terminal is enabled, N being an integer greater than 1; receiving an ultrasonic receipt signal; generating N determination results of whether the terminal is covered, wherein each of the N determination results is based on one of the N times transmission of the ultrasonic transmission-signal and receipt of the corresponding ultrasonic receipt signal; and determining that the terminal is covered and switching the screen state of the terminal from a turn-on state to a turn-off state, when at least one of the N determination results indicates that the terminal is covered. In the technical solution, whether the terminal is covered is determined by obtaining a value of the determination result for successive multiple times within a certain time period. Thus, it may improve the accuracy of the determination, and overcome the defects in the related art where incorrect determination causes misjudgment operation such as a screen flickering. As a result, user experience can be improved.

Method, device and storage medium for controlling screen state

A mobile terminal and an antenna determining method are provided. The mobile terminal includes a housing, a processor, at least two antennas and at least two pressure sensors. The pressure sensors are configured to acquire values of pressures applied to a surface of the housing and send the acquired pressure values to the processor; the processor is configured to receive pressure values sent by the pressure sensors, to determine at least one contact position between a user and the mobile terminal based on pressure values sent by at least one of one or more first side pressure sensors and at least one of one or more second side pressure sensors, to determine an antenna to receive or send signals from the at least two antennas based on the at least one contact position.

Mobile terminal and method for determining antenna

A method for switching a screen state, a terminal, and computer-readable medium are provided. The method includes: transmitting a transmission sound wave when it is detected that the screen state of the terminal is in a light-on state during a voice communication session, the transmission sound wave being a sound wave of a pre-defined frequency; determining a target detection region when a target receiving sound wave is received through a plurality of pre-installed sound wave receiving devices, the target receiving sound wave being formed by reflecting the transmission sound wave by a target object; and switching the screen state of the terminal from the light-on state into a light-off state when it is determined that the target object is located in the target detection region.

Method for switching screen state of terminal, terminal thereof, and computer-readable medium thereof

A sound recording method and device are provided in the field of multimedia processing. The method is applied in a mobile terminal including three microphones, including: acquiring three channels of sound signals collected by the three microphones; calculating a central channel signal, a left channel signal, a right channel signal, a rear left channel signal and a rear right channel signal in a multi-channel surround audio system according to the three channels of sound signals; calculating a bass channel signal in the multi-channel surround audio system according to the three channels of sound signals; and combining the above signals to obtain a sound signal of the multi-channel surround audio system.
