A mobile computing device includes: a housing having a front face, an opposing back face, and side walls joining the front and back faces; a microphone supported within the housing; and an acoustic channel extending between the microphone and an exterior of the housing, the acoustic channel defined by: (i) a microphone port traversing one of the side walls; (ii) a membrane assembly affixed to a first inner housing surface around the microphone port; and (iii) an isolation plate affixed to a second inner housing surface surrounding at least a portion of the first inner housing surface, the isolation plate having a channel opening therethrough and configured to engage with the membrane assembly.

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.

Disclosed is an electronic device including a structure that stably supports a flexible printed circuit board on which a microphone module is disposed inside the electronic device, thereby improving the sealing between the microphone module and the camera housing.

The present disclosure relates to an acoustic output apparatus. The acoustic output apparatus comprising: at least one low-frequency acoustic driver that outputs sound from at least two first sound guiding holes; at least one high-frequency acoustic driver that outputs sound from at least two second sound guiding holes; and a controller configured to cause the low-frequency acoustic driver to output sound in a first frequency range, and cause the high-frequency acoustic driver to output sound in a second frequency range, wherein the second frequency range includes frequencies higher than the first frequency range.

A terminal device and a sound-emitting apparatus arranged in the terminal device, where the terminal device includes a housing, a display is arranged on a surface of the housing, a notch is formed at an end of the display, and a camera system is arranged inside the housing. The camera system is arranged opposite to the notch in a direction perpendicular to the display, and a camera of the camera system is located inside the notch. A through-hole is arranged opposite to an opening of the notch in the housing in a direction parallel to the display.

A height channel speaker with an integrated acoustic reflector to reflect sound off of a ceiling down to a listener. The acoustic reflector compensates for thin transducers by creating a virtual image of the real sound source outside the speaker enclosure. The focal point of the acoustic reflector is controlled by modifying the curvature of the reflector surface. The transducer is mounted on an inclined plane to radiate sound in a rear-upward inclined direction. The acoustic reflector is mounted on the same inclined plane so that the radiant axis of the transducer is directly incident on the acoustic reflector surface. The sound is projected towards the ceiling in a forward, upward-inclined direction to reflect off the ceiling and down to the listener. The speaker can be acoustically occluded from the listener by a panel to which the speaker is attached.

Disclosed is an electronic device including a sound output module. The sound output module includes a sound output housing and a motor unit positioned in an inner space and communicating with an inner space of the speaker unit to generate a vibration force. The motor unit may include a motor body forming a volume space communicating with the inner space of the speaker unit and a vibration body positioned in the motor body to generate a vibration force. A communication hole may be formed in an outer wall of the motor body for the inner space of the speaker unit and the volume space to communicate with each other.

An example device includes an imaging portion, an audio portion and at least one acoustic isolation feature. The audio portion is integrally coupled to the imaging portion. The audio portion is to provide an audio output. The at least one acoustic isolation feature is to facilitate acoustic separation of the imaging portion and the audio portion.

An exciter includes a first yoke having a first accommodation space with a first open end, a second yoke having a second accommodation space with a second open end which faces the first open end, the second open end being spaced from the first open end in a vibration direction. The exciter further includes a first magnetic member accommodated in the first accommodation space, a magnetic core and a coil accommodated in the second accommodation space, the coil wound around the magnetic core, a second magnetic member accommodated in the second accommodation space and located at outside of the coil, and a copper tube wound around the magnetic core and sandwiched between the magnetic core and the coil. The copper tube is capable of suppressing the high frequency impedance of the coil and therefore improves the high frequency performance and the reliability of the exciter.

This application provides a decorating assembly, a housing assembly, and an electronic device. Gas flows between the outside of the electronic device, the first gap, the first channel, the breathable space, the waterproof breathable film, and the first space to implement a quick balance between internal air pressure of the first space and external air pressure of the electronic device. In addition, the waterproof breathable film is installed on the base, and the waterproof breathable film covers the breathable space, to ensure that when the decorating assembly is applied to the electronic device, the waterproof breathable film can prevent external liquid of the electronic device from entering the first space through the breathable space, thereby ensuring that the electronic device has relatively good waterproof performance.
