The invention provides a sounding device. The sounding device comprises a housing body with an accommodating space, a one-way inlet valve and a one-way outlet valve. A speaker unit partitions the accommodating space into a front cavity and a back cavity. The one-way inlet valve communicates the outside and the back cavity and is used for introducing air into the back cavity. The one-way outlet valve communicates the back cavity and the outside and is used for discharging the air in the back cavity outside. A first through hole communicating the outside and the back cavity is formed in the housing body. The invention also provides a mobile terminal. Compared with the related art, the sounding device and the mobile terminal of the invention have better reliability and better performance.

Aspects of the present disclosure provide an audio output mode adjustment structure that can include a sound output channel communicating an interior and an exterior of the electronic device and an adjusting unit. An opening of the sound output channel is located at the top of the electronic device. The adjustment unit moves relative to the opening of the sound output channel so that when the electronic device outputs audio in a loud-speaking mode, the adjustment unit does not cover the sound output channel, and sound waves propagate in a straight line through the opening of the sound output channel, and when the electronic device outputs audio in the handset mode, the adjustment unit covers the opening of the sound output channel, so that the sound waves propagate toward a display screen side of the electronic device through the opening of the sound output channel.

An antenna for a foldable electronic device which functions equally well in both folded and unfolded states includes a rotating shaft and a housing. The overall housing is made of metallic material and includes a first housing and a second housing. The first housing connects to the second housing through the rotating shaft. The housing further defines at least one group of slots to form at least one slot antenna. The at least one slot antenna crosses the rotating shaft and extends to the first housing and/or the second housing. By setting at least one slot antenna to correspond to the rotating shaft, the foldable electronic device achieves high radiation performance whether the first and second housing are folded or unfolded.

The objective of the present invention is to provide a mobile terminal in which a layout of execution screens of two or more applications displayed together can be automatically changed to be suited for a user's viewing. According to an aspect of the present invention, provided is a mobile terminal comprising: a body; a display coupled to the body such that a display area viewed from the front of the body can be changed according to the switching between an extension display mode and a contraction display mode; and a control unit for controlling such that a layout for two or more application execution screens displayed together on the display is changed in response to the switching from the extension display mode to the contraction display mode.

An electronic device, relating to the technical field of antennas. The electronic device includes a frame, a screen, and a circuit board assembly. A part of the frame forms a radiator of an antenna, or the radiator of the antenna is fixed on an inner side of the frame. The circuit board assembly is located on the inner side of the frame. The circuit board assembly includes a first conductive member, and a first board, an elevating board, and a second board sequentially stacked. The first board is located on one side of the second board away from the screen. The first board includes a first main body portion and a first extension portion connected to the first main body portion. The first main body portion is fixedly connected to the elevating board. The first extension portion protrudes relative to the elevating board and the second board, and is disposed close to the radiator.

A foldable electronic device is provided. The foldable electronic device includes a central body, a linkage unit, a plurality of operating mechanisms, and a plurality of panel bodies. The linkage unit includes a plurality of driving shafts. Each of the operating mechanism has a wing rod, a lifting plate, and a connecting rod. The wing rod is fixed to the lifting plate. The wing rod and the connecting rod pivotally connecting to the central body and the driving shaft respectively. When the panel bodies are in a folded status, a flexible screen is bent, and the wing rod, the lifting plate, and the central body collectively define a yielding space for accommodating a flexible section of the flexible section.

An electronic device of various embodiments of the disclosure may include: a housing, a wireless communication circuit disposed inside the housing and configured to transmit and/or receive a signal of a specified frequency by feeding to at least a part of the housing, and a display structure coupled to the housing. The display structure may include: a cover glass coupled to the housing and forming at least a part of a front surface of the electronic device, a display panel disposed adjacent to one surface of the cover glass, a first layer including a dielectric material disposed under the display panel, and having a first edge spaced apart from the first side surface by a first distance, and a second layer disposed under the first layer, wherein a second edge of the second layer corresponding to the first edge of the first layer is spaced apart from the first side surface by a second distance less than the first distance. An edge of the display panel corresponding to the first edge of the first layer may be spaced apart from the first side surface by a third distance greater than the second distance and less than the first distance.

An electronic device includes a camera module, wherein the camera module includes a lens assembly including lenses aligned along an optical axis, an actuator, a first magnet disposed on a first surface of the lens assembly, a first coil configured to move the lens assembly along the optical axis, a metal shield structure disposed on an outer surface of the actuator to face the first coil, and a fixing structure disposed on a third surface perpendicular to the first surface of the lens assembly, wherein at least a portion of the fixing structure has a magnetic property.
