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.

Electronic device with display module capable of producing sound

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.

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.

Electronic device

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.

Electrical device with piezoelectric elements communicating haptically and audibly with user

A holder for supporting a portable electronic device and includes a pedestal and a supporting board. The supporting board includes a resisting portion and at least one resonator portion. The resisting portion is mounted on and has a predetermined angle with a top surface of the pedestal. The resonator portion is connected to an edge of the resisting portion and extends from the edge towards a side contrary to the resisting portion a predetermined distance and then extends towards the resisting portion. The resisting portion and the top surface of the pedestal cooperatively support the portable electronic device. The resonator portion is configured to resonate and guide sounds generated by the portable electronic device.
