Abstract: The present invention discloses an electronic device, including a device housing, a sound apparatus, and a screen. The screen covers the device housing and is provided with a first sound hole at a joint with the device housing. The sound apparatus is disposed in the device housing, and the sound apparatus includes an apparatus housing and an electroacoustic module. The electroacoustic module includes a first diaphragm and a second diaphragm, the apparatus housing is connected to the first diaphragm and the second diaphragm, and the device housing is provided with a second sound hole. When the electroacoustic module is in a first state, the first sound wave formed by the vibration of the first diaphragm and the second sound wave formed by the vibration of the second diaphragm are in opposite phases.

Abstract: An earphone includes a loudspeaker, a rear housing and a front housing. The loudspeaker is disposed in the rear housing, a sound output hole is disposed at a first end of the front housing, a second end of the front housing is rotatably connected to the rear housing, and the front housing is rotatable relative to the rear housing and between a first position and a second position. In a case that the front housing is rotated to the first position relative to the rear housing, the sound output hole faces a first direction, and the loudspeaker is configured to output a first channel audio signal. In a case that the front housing is rotated to the second position relative to the rear housing, the sound output hole faces a second direction, and the loudspeaker is configured to output a second channel audio signal.

Abstract: An electroacoustic module includes an installation member, first and second sounding devices. The installation member includes first and second installation cavities, first and second sound outlets, and a sound guide channel. The first sounding device in the first installation cavity divides the first installation cavity into a first front cavity connected to the first sound outlet and a first rear cavity. The second sounding device in the second installation cavity divides the second installation cavity into a second front cavity connected to the second sound outlet and a second rear cavity which is a closed cavity and which is connected to the first rear cavity through the sound guide channel. A phase of a first sound wave emitted by the first sounding device through the first sound outlet is different from a phase of a second sound wave emitted by the first sounding device through the second sound outlet.

Abstract: An electronic device includes a display module, a middle frame, a sound-emitting assembly, a first circuit board, a first structural member, and a back shell. The middle frame is provided with an accommodating groove. The display module is disposed in the accommodating groove. The sound-emitting assembly, the first circuit board, the first structural member, and the back shell are disposed on a side, away from the display module, of the middle frame. The sound-emitting assembly, the first circuit board, and the first structural member are located in an installation cavity formed by the back shell and the middle frame. The sound-emitting assembly includes a housing and a sound-emitting component. The housing is provided with a first cavity, and the sound-emitting component is located in the first cavity. The first structural member and the first circuit board form first space by enclosure.

Abstract: An electronic device is provided. The electronic device includes: a display module, a middle frame, a sounder, a first structural member, a first circuit board, and a rear cover, where the middle frame is provided with an accommodation groove, and the display module is disposed in the accommodation groove; a side of the middle frame away from the display module is provided with a mounting groove, and the sounder is at least partially disposed in the mounting groove; the first structural member and the rear cover are disposed at the side of the middle frame away from the display module, a first gap is present between the first structural member and the rear cover, and the first structural member and the middle frame enclose a first sound chamber of the sounder, or the first structural member and the first circuit board enclose a first sound chamber of the sounder.

Abstract: An earphone includes a loudspeaker, a rear housing and a front housing. The loudspeaker is disposed in the rear housing, a sound output hole is disposed at a first end of the front housing, a second end of the front housing is rotatably connected to the rear housing, and the front housing is rotatable relative to the rear housing and between a first position and a second position. In a case that the front housing is rotated to the first position relative to the rear housing, the sound output hole faces a first direction, and the loudspeaker is configured to output a first channel audio signal. In a case that the front housing is rotated to the second position relative to the rear housing, the sound output hole faces a second direction, and the loudspeaker is configured to output a second channel audio signal.

Abstract: Smart glasses are disclosed, including a glasses body (100) and temples (200), where the glasses body (100) and the temples (200) are rotatably connected, at least one of the glasses body (100) and the temples (200) is provided with a first electrical connector (300), and the smart glasses include a folded state and an unfolded state; in a case that the smart glasses are in the folded state, the first electrical connector (300) is exposed on the smart glasses; and in a case that the smart glasses are in the unfolded state, the first electrical connector (300) is covered by at least one of the glasses body (100) and the temples (200).
