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: A new design of shoe sole that includes both a base portion and a base support portion, wherein the base support portion is a base support portion attached underneath to the center area of the base portion. The current design further includes an expansion portion that extends downwardly from the outside rim of the base portion, wherein the expansion portion is elastic, and the bottom surface of the base support portion is higher than the bottom surface of the expansion portion. Footwear made of this type of sole first touch a support surface (ground) with the expansion portion, which forms a first contact region. Further because the expansion portion is located at the outward rim of the base portion, it is easier for the expansion portion to extend to all directions when pressed.
