The present application relates to the technical field of audio device, and in particular discloses a speaker assembly, a microphone and a smart portable karaoke system. The speaker assembly includes an accommodating groove for storing a microphone. When the microphone is in the accommodating groove, the microphone has two states: a sunken state, in which the microphone is configured to slide downwards with respect to the accommodating groove and is locked in the accommodating groove when being pushed for the first time; and a lifted state, in which the microphone is released and is configured to slide upwards with respect to the accommodating groove when being pushed again. The speaker assembly provided by the present application can effectively solve the problem that the microphone is inconvenient to carry and accommodate.

The present invention is related to a water dispersible paper, particularly for use in packages in the construction area. The dispersibility of the paper of the present invention is achieved due to the low wet resistance and high capillary absorption and basically consists of an unbleached cellulose-based paper aiming at the reduction of ingredients conventionally used, adding only defoamers and drainage aids in the formulation thereof. The paper of the present invention consists in the elimination of the use of disintegration aids (such as surfactants), gluing agents and dry resistance agents (such as starch). There is further described a manufacturing process for dispersible paper which allows obtaining a paper having low wet tensile strength and high capillary rise without the need for the chemical agents usually known for the manufacture of this type of paper. The present invention further foresees a package containing said paper for use in construction such as in packages for, lime, sand, cellulosic or synthetic fibers or powder pigments, among others.
