A mobile terminal device and methods are disclosed. A casing has a plurality of surfaces. A display module is provided on a first surface of the casing and displays a screen including an object. A first detection module is provided to overlap at least part of the display module and detects an operation performed on the display module. A second detection module is provided on a second surface opposite to the first surface and detects a movement operation for moving the screen. A control module cuts out at least a partial region including the object from the screen and moves the cut region according to the movement operation, when the movement operation has been detected.

Mobile terminal device, screen control method, and non-transitory computer readable storage medium

Disclosed is a class-D amplifier including a first output circuit, a first capacitor, a pulse width modulator, and a slew rate limiting amplifier. The first output circuit includes first and second switching devices that are connected in series between first and second power supply lines. The first capacitor is connected between the first and second power supply lines. The pulse width modulator generates a pulse width modulated switching signal based on a triangular wave and an audio signal, and provides the switching signal to the first output circuit. The slew rate limiting amplifier is connected to an input part of the pulse width modulator to which the audio signal is provided, and limits a slew rate of output. The sound-producing device is connected in series to an inductor connected to a first output node of the first output circuit. The sound-producing device and the inductor constitute an LC filter.

Class-D amplifier and electronic apparatus

A mobile terminal device is disclosed. The device includes a display module, a communication module, a sound input module, a sound output module, a hold detection module and a control module. The communication module is configured to receive an incoming call. The sound input module is configured to receive sound from a user. The sound output module is configured to output sound of the call. The hold detection module is configured to detect that the mobile terminal device is held. The control module is configured to perform a process of notifying the caller that the user cannot take the call when the communication module receives an incoming call, the hold detection module detects that the mobile terminal device is held and then the hold detection module detects that the mobile terminal device is not held.

Mobile terminal device

A mobile terminal device and methods are disclosed. A display module is provided on a first surface of the casing. A first detection module is provided to cover the display module and detects a user's operation. A second detection module is provided on a second surface opposed to the first surface and detects a user's operation. A lock control module sets a lock function for preventing the user's wrong operation. The lock control module releases the setting of the lock function, if the lock function is set and if the first detection module has detected a first operation. The lock control module releases the setting of the lock function, if the lock function is set and if the second detection module has detected a second operation.
