Abstract: The disclosure relates to an electronic device and a method thereof for managing an application menu structure. The application menu structure includes a main menu having a list of main options. The electronic device includes a display module, a calculation module, and a display module. The calculation module calculates usage frequency of each of the main options. The disposition module disposes one of the main options having greatest usage frequency at the center of the display module and disposes another one of the main options having a non-greatest usage frequency to surround the one of the main options of the greatest frequency on the display module.

Abstract: A loudspeaker module includes a hollow main body, two rotatable connecting portions, and two loudspeakers. The hollow main body includes two opposite sidewalls. Each of the opposite sidewall defines a first opening, an inner sidewall of the first opening defines an annular rotating slot. One end of the connecting portion extends an annular flange shaped corresponding to the rotating slot. The two rotatable connecting portions are respectively rotatably connected to the main body via the flange rotating about the rotating slot. Two loudspeakers are disposed in an end of the corresponding rotatable connecting portion away from the main body.

Abstract: A light source module includes a light source and housing. The housing includes a reflecting part, an installed part, and a stop. The reflecting part includes a paraboloidal surface configured for reflecting light beams from the light source. The light source is set in a focal point of the paraboloidal surface. The installed part is configured for installing the light source. The opening is configured for transmitting light beams reflected from the paraboloidal surface. The stop is perpendicularly connected with the installed part, and configured for preventing light beams from the light source from directly passing through the opening.

Abstract: A portable sound box includes a main body and a clip. The main body includes a battery for supplying power to the portable sound box. Thus, the portable sound box can supply power on its own. The clip is fixed to the main body and configured for clipping to an external object. Thus, the portable sound box can attached to the external object instead of standing on a surface.

Abstract: A keyboard includes a keypad portion, a base board, an illuminating device, and a circuit board. The keypad portion is mounted to the base board. The illuminating device is electrically connected to the circuit board and is further fixed to the base board surrounding the keypad portion. The circuit board is configured to supply the illuminating device with power. When powering the illuminating device, the keyboard can be used in a dark environment.

Abstract: An electronic device includes a memory storage device, a storing unit, and a voltage increasing unit. The storing unit is used for receiving the supply voltage to store energy and releasing energy to generate an standby voltage when the power supply stops providing the supply voltage. The voltage increasing unit is used for receiving the standby voltage, increasing the standby voltage, and providing the increased standby voltage to the memory storage device for preventing data loss in the memory storage device. A related method for preventing data loss in a memory storage device and an electronic device assembly are also provided.

Abstract: A receiving module, checking module, and a controller are provided. The receiving module is configured for receiving external wireless signals. The checking module is configured for checking whether a current wireless signal comprises checking codes of a control signal which is configured for controlling the electronic device and, if yes, generating an activation signal. The controller is configured for switching the electronic device into a power-saving mode if no external wireless signal is received after a predetermined time period and switching the electronic device into a normal mode if the activation signal is received.

Abstract: A device includes a main body and a table stand connected to the main body for supporting the main body. The main body comprises a receiving portion and a plurality of locking grooves. The table stand received in the receiving portion comprises a retaining board and a turning board. The retaining board is operable to be selectively inserted into one of the locking grooves, such that the retaining board and turning board are capable to form different angles to place the main body at different viewing angles.

Abstract: A portable electronic device includes a main body and a frame. The main body includes a front shell, a back shell engaging with the front shell, and a touch panel mounted on the back shell. The frame is mounted on the back shell. The touch panel is surrounded by the frame. The frame extends beyond the surface of the touch panel.

Abstract: A massage apparatus and a massage method are provided.

Abstract: An electronic device includes a main body and a table stand connected to the main body for supporting the main body. The main body comprises a positioning member. The table stand defines at least two positioning holes. The table stand is operable to rotate relative to the main body. The positioning member is operable to be selectively inserted into either one of the at least two positioning holes, such that the table stand is operable to form a corresponding predetermined angle with the main body.

Abstract: A touch control method for operating a touch screen includes: obtaining a to-be-operated object according to user's operations; detecting coordinates A(XA, YA) of a first touch point with respect to the to-be-operated object on the touch screen; detecting coordinates B(XB, YB) of an initial point of a second touch point; obtaining an operating center C(XC, YC) according to the coordinates A(XA, YA) and B(XB, YB); detecting coordinates B?(XB?, YB?) of the second touch point after the second touch point is moved; computing lengths of the two vectors CB and CB? according to the coordinates C(Xc, YC), B(XB, YB), and B?(XB?, YB?), and computing a zoom coefficient K according to the lengths of the two vectors CB and CB?; and zooming in or out the to-be-operated object according to the zoom coefficient K around the operating center C(XC, YC).

Abstract: An exemplary touch control method includes, first, obtaining a to-be-operated object according to a user's operation. A second step is detecting coordinates A(XA, YA) of a first touch point. A third step is detecting coordinates B(XB, YB) of an initial point of a second touch point. A fourth step is obtaining an operating center C(XC, YC) according to the coordinates A(XA, YA) and B(XB, YB). A fifth step is detecting coordinates B?(XB?, YB?) of the second touch point after the second touch point is moved. A sixth step is computing an angle ? between two vectors CB and CB? according to the coordinates C(XC, YC) and B(XB, YB). A seventh step is rotating the to-be-operated object by the angle ? around the operating center C(XC, YC).
