    Abstract: An electronic device is provided. The electronic device includes a first body, a second body, a speaker cabinet and a link mechanism. The second body rotates relative to the first body by a hinge. The speaker cabinet, disposed in the first body, is selectively lengthened or shortened. The link mechanism connects the hinge with the speaker cabinet. When the second body is closed relative to the first body, the speaker cabinet is concealed in the first body, and when the second body is opened relative to the first body, the hinge drives the link mechanism to press the speaker cabinet, enabling the speaker to be lengthened or to be shortened.

    Abstract: The present invention provides an apparatus and method for noise cancellation of voice communication. The apparatus includes a main body, loudspeaker, in-ear microphone, speaking microphone and adaptive control system. The method includes an external noise microphone arranged externally onto the main and used to acquire the noise outside of the ear drum, which is taken as the reference noise signal of adaptive control system. The in-ear anti-noise is estimated, so that the noise disturbance can be reduced when the receiving end receives remote voices. After noises and near-end voices are separated from near-end voices subjecting to noise disturbance, so that the accuracy of estimating anti-noise and the applicability of active noise cancellation is increased.

    Abstract translation: 本发明提供了一种用于语音通信的噪声消除的装置和方法。 该装置包括主体,扬声器,入耳式麦克风,讲话麦克风和自适应控制系统。 该方法包括外部设置在主体上的外部噪声麦克风,用于获取耳鼓外部的噪声,作为自适应控制系统的参考噪声信号。 估计入耳式抗噪声,从而当接收端接收到远程语音时可以降低噪声干扰。 噪声和近端声音与噪声干扰的近端声音分离,从而提高了抗噪声的准确性和主动噪声消除的适用性。
