The utility model is owing to be provided with the convex edge at the inner surface of audio amplifier upper casing and the inner surface of audio amplifier mesochite, and the phase clamping of described convex edge forms the button of checking card, thereby makes audio amplifier upper casing and audio amplifier mesochite convenient fixing, reliable.
Description of drawings
Fig. 1 is the schematic diagram of the utility model embodiment.
Wherein: 1, audio amplifier upper casing; 2, audio amplifier mesochite, 3, convex edge; 4 projections; 5, convex edge.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and preferred embodiment.
Miniature loudspeaker box with flexible resonator of the present utility model comprises audio amplifier upper casing, audio amplifier mesochite, audio amplifier lower casing and flexible resonator, and the inner surface of described audio amplifier upper casing and audio amplifier mesochite is provided with to check card to be buckled.
As shown in Figure 1, described audio amplifier upper casing 1 inner surface edge be provided with convex edge 3, the edge of the inner surface of described audio amplifier mesochite 2 is provided with projection 4, also is provided with outside convex edge 5 on the projection 4 of described audio amplifier mesochite 2 inner surfaces, and projection 4 and the convex edge 5 of described audio amplifier mesochite inner surface are perpendicular.The convex edge of audio amplifier mesochite inner surface can with the mutually clamping of convex edge of the inner surface of audio amplifier upper casing, form the button of checking card, thereby audio amplifier upper casing and audio amplifier mesochite fixed.
The button quantity of checking card in the present embodiment is 3, as long as the quantity of the button of certainly checking card is at least 2, fixing of audio amplifier upper casing and audio amplifier mesochite is just reliable.
Outer surface at voice box casing also is provided with a groove simultaneously, and described groove can be arranged on the outer surface of audio amplifier upper casing, audio amplifier mesochite or audio amplifier lower casing.When dismounting audio amplifier upper casing and audio amplifier mesochite, can will exert oneself described in the point set on the groove, thus for convenience detach, can also play beauty function.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that implementation of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
