Abstract: An earphone of adjustable size to fit the ears of different users includes a housing, a speaker, an air path, an inflatable earplug, and a control assembly. The speaker and at least one part of the air path are arranged in the housing. The inflatable earplug communicates with the air path and is detachably attached to the housing. The control assembly is arranged outside of the housing and configured to inflate and deflate the inflatable earplug through the air path.

Abstract: An electronic device includes a circuit board, a protective assembly, and a protective film. The protective assembly providing a cavity is arranged on one side of the circuit board. The protective assembly includes a first protective unit and a second protective unit. A third through hole communicating with the cavity is defined in the first protective unit. A supporting surface is defined on the second protective unit facing the third through hole. A projection of the third through hole is overlapped with a projection of the supporting surface along the first direction. The protective film is coupled to the protective assembly and arranged in the cavity to divide the cavity into a first cavity and a second cavity. The above-mentioned electronic device resists deformation of the protective film by setting the second protective unit between the circuit board and the protective film.

Abstract: A display module includes a middle frame, a display screen, a coil, and a magnet. The display screen is arranged on the middle frame. The display screen and the middle frame cooperatively define a receiving space. The coil defines an accommodation space. A portion of the magnet is accommodated in the accommodation space. The magnet and the coil are received in the receiving space. One of the magnet and the coil is arranged on the display screen, and the other one of the magnet and the coil is arranged on the middle frame.

Abstract: An electrical device providing audible and haptic communication with its user includes a touch screen, an array of piezoelectric elements, a memory, and a processor. The touch screen is divided into touch regions and each touch region carries one piezoelectric element. When receiving touch inputs from a user, the processor uses data and programs stored in the memory to (1) determine which touch region the touch input is located in, (2) determine which piezoelectric element corresponds to the determined touch region, and (3) vibrate the determined piezoelectric element at a predetermined frequency. The electrical device can output sound by (1) obtaining a signal of the sound to be output and (2) vibrating the piezoelectric element, or more than one at different predetermined frequencies, to output an audible sound.

Abstract: An electronic device with a full-screen display and L-shaped sound channel is disclosed. The device includes a display, a cover, a frame and a sound assembly. The frame includes bottom and side walls, and the sound assembly includes a sound output hole, a sound channel and a sound generating module. The sound output hole is defined between a notch of the cover and the side wall. The sound channel is formed in the frame and includes first and second channels. The first channel is formed by horizontal cutting and the second channel is formed by vertical cutting. The first and second channels are interconnected and communicate with the sound output hole. Sound generated by the sound generating module is transmitted to the sound output hole through the sound channel. A method for manufacturing the electronic device is also disclosed.

Abstract: A wearable electronic device includes a band, a gas inlet member, and a gas outlet member. The band defines a sound chamber. The gas inlet member and the gas outlet member are both positioned on the band and communicated with the sound chamber. When the gas inlet member is pressed, air enters into the sound chamber and the sound chamber expands to an expanded state. When the gas outlet member is pressed, the air is exhausted from the gas outlet member and the sound chamber restores to an original state.
