    Abstract: A microphone bed for receiving a microphone. The microphone bed including a first compressible portion and first and second non-compressible portions. The first compressible portion is formed to accommodate a first end of the microphone. The first non-compressible portion has the compressible portion coupled thereto, the non-compressible portion having a length that is over half a length of the microphone. The second non-compressible portion is coupled to the first non-compressible portion, which together form a cavity therebetween, the second non-compressible portion having a floor. There is a weighted feature extending upward from the floor of the second non-compressible portion.

    Abstract: An earphone and a mobile terminal is provided, in which the earphone includes a housing and a speaker assembly. The housing internally includes a front cavity and a rear cavity that are separated by the speaker assembly. The front cavity is located on a side that is of the speaker assembly and that is a sound output direction, and the rear cavity is located on an opposite side of the sound output direction of the speaker assembly. One or more sound guide channels are disposed in the housing, each sound guide channel is disposed in a sidewall of the housing, and each sound guide channel is configured to: when the earphone is normally worn, connect air inside an ear canal of a user to air outside the ear canal without connecting air in the front cavity to air in the rear cavity.

    Abstract: A speaker box includes a housing and a speaker unit accommodated in the housing. The speaker unit includes a diaphragm configured to vibrate and sound. The diaphragm is spaced from the housing to form a front sound cavity therebetween. The speaker box further includes a sound transmitting channel communicating the front sound cavity with outside. The front sound cavity and the sound transmitting channel cooperatively form a front cavity of the speaker box. A sound absorption layer is disposed at a portion of the housing facing the front cavity. The sound absorption layer includes a micro-porous structure. When the sound wave passes through the front cavity, the sound absorption layer is capable of absorbing the resonance vibration of the front cavity in high frequency, thus suppressing the amplification of the sound distortion due to the resonance vibration of the front cavity and improving the acoustic performance of the speaker box.

    Abstract: Wearable devices may include a housing including a first surface facing a first direction and having a speaker nozzle part, and a second surface facing a second direction opposite to the first direction and having at least one microphone hole. A speaker and a microphone are disposed in the housing, the microphone configured to collect an acoustic signal. A partition wall is positioned between the speaker and the microphone. A first space is defined between the speaker and the partition wall, a first path is provided for connecting the speaker and the speaker nozzle part, and a second path, separated from the first space by the partition wall, connects the microphone and the first path.
