Fig. 2 is the schematic appearance of the two passive basins of the utility model inverter type;
Fig. 3 is the vertical view of the two passive basins of the utility model inverter type;
Fig. 4 is the front view of the two passive basins of the utility model inverter type;
Fig. 5 is the fundamental diagram of the two passive basins of the utility model inverter type;
Fig. 6 is the utility model actual measurement frequency response curve comparison diagram.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
See also Fig. 1, Fig. 1 is the schematic appearance of the utility model audio amplifier, and is as shown in Figure 1; Audio amplifier comprises voice box casing and by its sealing audio amplifier cavity that constitutes, the upper surface of said voice box casing is provided with dismountable top cover, is provided with dividing plate in the said sealing audio amplifier cavity; The header board of said voice box casing is provided with 2 loud speakers, and the back plate of said voice box casing is provided with and 2 two passive basins of 2 inverter types that loud speaker is symmetrical, please combine to consult Fig. 2; Fig. 2 is the schematic appearance of the two passive basins of the utility model inverter type, and is as shown in Figure 2, and the size of the two passive basins of inverter type is made according to the size of audio amplifier; In audio amplifier that it is packed into, what deserves to be mentioned is that the number of the loud speaker in the present embodiment is identical with the number of the two passive basins of inverter type; In other embodiments; The number of the two passive basins of inverter type can be a plurality of, and those skilled in the art should understand, and repeats no more here.
See also Fig. 3 and Fig. 4; Wherein, Fig. 3 is the vertical view of the two passive basins of the utility model inverter type, and Fig. 4 is the front view of the two passive basins of the utility model inverter type, in the present embodiment; The two passive basins of said inverter type comprise the passive Caloris Basin of the first passive Caloris Basin 1, second 2, air slot 3 and in order to support the bracing frame 4 of the first passive Caloris Basin 1 and the second passive Caloris Basin 2; Should be noted that the said first passive Caloris Basin 1 and the said second passive Caloris Basin 2 all in the form of a ring, its surface is all with film.
