A speaker includes an upper housing; a lower housing assembled with the upper housing to define a receiving space; and a speaker unit received in the receiving space and including a diaphragm. The upper housing includes a top wall, a side wall extending from the top wall towards the lower housing, and a blocking wall extending from the top wall along a direction facing away from the top wall and spaced apart from the side wall. The blocking wall, side wall and top wall define a receiving portion receiving the speaker unit. A breathable spacer is provided at an end of the top wall and is spaced apart from the lower housing to form first sound absorbing cavity. A side of the blocking wall facing away from the speaker unit, the side wall and the lower housing define second sound absorbing sound cavity communicating with the second sound absorbing cavity.

Speaker

The present disclosure discloses a speaker box which includes an upper cover, a lower cover fixed to the upper cover in a covering manner and forming an accommodating space with the lower cover, and a sound unit accommodated in the accommodating space. The sound unit and the upper cover define a front cavity. The sound unit, the lower cover and the upper cover define a rear cavity together. The speaker box further includes a cover plate fixed to one side of the upper cover away from the lower cover, and an air-permeable isolating member. The cover plate and the upper cover are separated and define an auxiliary cavity which is filed with sound-absorbing particles. The air-permeable isolating member is fixed to the upper cover and completely covers the through hole, and the air-permeable isolating member encloses the sound-absorbing particles in the auxiliary cavity.

Speaker box

The disclosure provides a method for frequency reuse in a wireless relay scenario, wherein a center frequency spectrum, an edge frequency spectrum and a random access frequency spectrum are pre-allocated to a cell according to a scenario parameter in the cell; load conditions of all mobile stations (MSs) covered by each relay station (RS) in the cell is calculated and reported to a base station (BS); the BS allocates the random access frequency spectrum to an RS according to load conditions of all RSs and schedules MSs. The disclosure also provides a system for frequency reuse in a wireless relay scenario. With the method and system above, the frequency spectrum planning is configurable, the random access frequency spectrum is introduced, and both the load balancing and user fairness are taken into consideration, which improves the throughput at the edge of the cell, especially can increase the throughput for the users whose throughput ranks poorly.
