Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further:
With reference to Fig. 1, a kind of miniature loudspeaker box with flexible resonator described in the present embodiment, comprises housing 1 and is arranged on loudspeaker 2, circuit board 3, guidance set 4 and the flexible resonator 5 of housing 1 below.Described flexible resonator 5 is connected with guidance set 4, housing 1 respectively.Described loudspeaker 2 are fixed on guidance set 4, and loudspeaker 2 are electrically connected with circuit board 3.
Described housing comprises 1 one outer cover bodies 11, a guard 12 and for a mounting bracket 13 of described guard 12 is installed.It is planar that the outer surface of described outer cover body 11 is circular arc, and Qie Qi center offers the hole 14 that amplifies.The shape size in this hole 14 that amplifies is identical with described guard 12.
Described mounting bracket 13 inner hollow, and both ends open.Described guard 12 is fixed on one end of mounting bracket 13.The end that guard 12 is installed on mounting bracket 13 convexes with an annular wall 131 to surrounding.This annular wall 131 is fixedly connected with the inner surface of outer cover body 11.Described guard 12 will described in the hole 14 that amplifies cover completely.This guard 12 enters in housing 1 from the hole 14 that amplifies for preventing the impurity such as dust.
Guiding when described guidance set 4 carries out stretching motion for described flexible resonator 5.This guidance set 4 comprises a connection piece 41, some the first guides 42 and one second guide 43.Described the first guide 42 is fixed on connector 41, and described the second guide 43 is fixed on an end of flexible resonator 5, and this second guide 43 and the first guide 42 are slidably matched.
