Detailed Description

In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention. The present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 to 4, the utility model provides a pair of slim loudspeaker, including casing 1, install in the loudspeaker subassembly 2 of casing 1 and the mechanism 3 that amplifies that is used for the bass effect of amplification, 1 inside hollow structure that is of casing, mechanism 3 that amplifies with loudspeaker subassembly 2 set up in the both sides of the same terminal surface of casing 1.

The utility model discloses at the during operation, loudspeaker subassembly 2 is because of the vibration sound production, and loudspeaker subassembly 2 is whole all takes place the vibration, and loudspeaker subassembly 2 is just directly can transmit to the external world to an end face in the external world because of the sound wave that the vibration produced this moment, and loudspeaker subassembly 2 is back to the sound wave warp of an external terminal surface casing 1 transmits extremely amplification mechanism 3 sends to the external world, has realized the amplification of sound wave through the mutual stack of sound wave to the utilization ratio of sound wave has been promoted, the low frequency sound that also can clearly send after making 1 thickness of casing reduce.

In this embodiment, the amplification mechanism 3 includes two acoustic wave radiation plates 31, and the two acoustic wave radiation plates 31 are arranged side by side in the housing 1.
